**Official Clevo P75xZM "Batman" / Sager NP9752 Owner´s Lounge** Welcome to the Batcave!

Alright people, since us prospective ZM owners are getting kinda impatient and are starting to suffer from claustrophobia in our little ZM thread, I decided to open up this Owner´s Lounge and welcome THE BATMAN into our midst!

Why "Batman" u ask? Look at those friggin bat-ears on the lid!

Before going into externals, internals and the detailed spec sheet, here are the most important highlights for this machine (and to make sure that people don´t start asking silly questions ):

DESKTOP CPU - up to Core i7-4790K with probable compatibility for 5th Gen Broadwell Core Models! (due to Z97 chipset)

MXM GPU - up to 980M with 8 GB GDDR5 (need I say more? none of that soldered, vRAM gimped crap)

PSU - Stock 230W upgradeable to 300/330W Clevo models (for that extra bit of overclocking juice )

DIMENSIONS - max. thickness of 35-36mm (putting it in perspective: that´s THINNER than current P150 series laptops at 43-47mm with MOBILE CPU!)

COOLING - A total of 7 (yes, that´s SEVEN!) heatpipes connected to both CPU & GPU with a two fan design

NO OPTIMUS - no driver installation hassles, no added display output delay, freedom for 3D capability, overclockable display refresh rate!

TWO M.2 PCIe PORTS - Breaking the SATA barrier and moving towards 2 GB/s throughput!

HIGH-RES SCREEN SUPPORT - up to 4K IPS (may vary depending on reseller/vendor)

VISUALS - Heck, who doesn´t like Batman?!
TWO USB 3.1 PORTS - damn straight, its got ASMedia´s ASM1142 chip integrated, supporting up to two USB 3.1 ports with 10Gbps bandwidth
--> unfortunately, this turned out to be false, even though the Clevo Service manual clearly lists the USB 3.1 capable ASMedia chip ASM1142. See this post for further info!

Nuff´said for now, I´ll let some nice images take care of the rest (courtesy of "the usual leaks", bluemobility, mySn and CEG, you guys rock!

Enjoy!!!

General Screen questions​

What screen options are available for the batman?

FHD Panels

LVDS

LG LP156WF4 - (78% sRGB/ 72% NTSC) 35ms

eDP
AUO B156HAN01.2 - (96% sRGB/ 74% NTSC) 25ms
LTN156HL01 - 96% sRGB/ 74% NTSC 16 ms'

3K Panel(s)
Panasonic VVX16T028J00 (72% NTSC)

4K Panel(s)
Sharp LQ156D1JW04 (72% NTSC)
Samsung (LTN156FL02-L01) (72% NTSC)

Which is better Matte or Gloss?
This is a personal preference and varies greatly depending on the type of environment you use your laptop in.

Is there a difference between LVDS and eDP?
Generally speaking: LVDS for FHD and eDP for high-res Displays
There are, however, also eDP FHD screens available. eDP is basically the "newer" LVDS version and should be considered as its successor in the long term.

IPS vs TN?
IPS: wide viewing angles, better color reproduction
TN: faster response times, cheaper

interesting article in this regard (thx to lunap for this link!): http://ift.tt/1KZHJXa

What is Gamut and what is acceptable?
Gamut is a term that generally describes the accuracy of color reproduction in a display. The higher the Gamut, the more colors a display can reproduce. Lower-Range Displays sport 60% Gamut, Standard is 72%, whereas High-End Displays start around 90% up to 95 or even 100% in rare cases. What is "acceptable" is up to you and your personal needs. Office work doesnt need anything above 60-72%, Gaming is totally fine with 72%, everything above is only REALLY important for image / video editing and creative work (or people with OCD )

Screen refresh (ms) and common myths?
General rule of thumb: the lower the refresh rate in ms, the less ghosting is discernible, especially in high-speed games such as FPS. Manufacturer info cant be trusted though, since 25 ms, even though regarded as comparably high / slow, does not show any ghosting on high-res IPS displays (based on user reports). Best to ask actual owners or check for yourself!

4K Screens​

Is there a difference between the Sharp and the Samsung 4k Panels?
Depends on how you define "difference". The underlying Panel tech is different (Sharp IGZO IPS RGB Stripe vs. Samsung LPS Pentile Matrix, Google is your friend!) and on paper and controlled testing environments, the Sharp panel beats the Samsung panel in pretty much all aspects. If you, the user, notice a difference side by side, however, is a completely different story and depends, as so many other things do, on your personal preference / sensibility to such things.

What are expected frame rates in games/performance loss?
Based on DSR reviews, one can expect about 50% performance loss on a 3K panel at identical Software and Hardware settings when comparing it with a FHD screen. With 4K, that number increased to about 70-80%.

Can I downscale?
Sure thing! And the scaling isnt even all that bad on 3K and 4K screens, its actually pretty crisp based on my own experience (see sig) and other user reports

3K Screens​

Which resolutions scale well with 2880x1620p?
1080p looks great on my 3K display and I´ve seen user reports saying that scaling down to 720p is fine, although more blurry than higher resolutions. So as long as u stay at 1080p or above, u should be fine even when downscaled.

Can I downscale?
Yes you can, see 4K Screens.

What frame rates would I be expecting?
See 4K Screens for reference.

What is the performance difference between 3k and 4k gaming wise?
Depending on the game / application I would say to expect a performance loss of around 40-60%.

Can I upgrade to a 4k screen later if want to?
Yes, since 3k and 4k screens both use the same connector this won't be an issue. Please see Screen options for a list of compatible screens. However, you cannot upgrade from a FHD screen to a 3K or 4K screen, since they use different cables and sometimes even different connectors! (see LVDS vs. eDP, for reference)

Can I downgrade to FHD if I don't like it?
Yes you can, just make sure its an eDP compatible panel! On the other hand, its impossible to upgrade from an FHD to a 3K/4K panel.

FHD(1080p) Screens​

Which Screen do you recommend?
Check the "MOD Section" on Luna´s summary of the best available 15.6" FHD displays.

Can I swap eDP to LVDS if I want to change to a higher gamut?
Suuuure, just grab a soldering iron, completely revamp your motherboard and youre good to go

Common CPU Questions​

What CPU's are offered?
Basically all CPU models compatible with the LGA1150 socket: http://ift.tt/20xAKAk

cool thing about this: future Broadwell CPUs will use the same socket

To K or not to K and why?
K CPUs are unlocked in every way possible. If you like to tweak and get the most out of your Hardware, then by all means go for a K model. If you just want to run your hardware out of the box and cannot bother spending time tweaking, then K is not for you! As easy as that

I only plan on gaming, which CPU would be best for me?
If you are simply gaming and nothing more and are on a budget then the i5 would be the best option, however if you are able then the i7 would be far more viable as it makes use of HT which many games these days can make use of especially if you're playing high end MMO's or multiplayer (BF4 etc) Video editing, and other tasks.

i5 vs i7
See Hyperthreading for more information.

i7 generally sports more CPU Cache.

I5 does not make use of HT, which i7 has.

Common misconception: I5 is the best chip for gaming because it is faster.. FALSE i5's are not better for gaming, they are more cost effective for gaming.

Hyperthreading on (BF3 Multiplayer)

Hyperthreading off (BF3 Multiplayer)

Understanding Hyperthreading
Please see http://ift.tt/1KZHJXe

4790K vs 4790S?
See section "To K or not to K and why?"

Does lower TDP = lower temps?
Yes and no. Generally, TDP describes the power envelope, in which the CPU is allowed to boost to its max. possible clocks. Depending on the CPU model, a lower TDP could mean lower clocks and thus lower peak temps. In other cases it does not make any difference whatsoever, because the voltages and clocks applied cannot saturate the given TDP envelope.

Things to keep in mind:
high Voltage = high Temps
high Clocks = higher Voltage necessary = higher Temps
high TDP = more room for the CPU to "stretch its legs" thermally and wattage/power-wise

GPU QUESTIONS​

Why is there no Optimus? Isn't Optimus good?
Depends on what your needs are. If youre primarily focused on battery life, then sure, Optimus is great! But check the benefits of NOT having Optimus below

Benefits of no Optimus.
- You can OC your internal/external display to 120hz or higher (if supported)
- You can drive higher resolutions on external displays
- You have no input lag when driving external displays or gadgets like the Oculus Rift
- You have the possibility to drive applications in 3D

970M vs 980M which is best for my needs?
How am I supposed to know what your needs are?!?!
But seriously, if you plan to upgrade every 1-2 years anyways, then the 970M is enough for you. Keeping your machine for 3 or more years, however, would probably shift the focus to the 980M for being more future-proof. It also depends on your everyday usage of the GPU. Are you always playing the latest games and NEED to have every settings maxxed out? As hinted before, the best judge of your needs is YOU! So be check reviews, be aware of the 30% performance gap between the two GPUs and check what u plan to do with the gpu, then the answer will present itself to you. Of course, dont forget your available budget

How much hotter does the 980M get?
"Hot" is a term that is completely misplaced when it comes to Maxwell chips. Personally, I cannot seem to get my 980M to even break 70C, no matter what I throw at it! Nuff said...

Can I overclock the 970M to be like the 980M?
It is indeed possible to push the 970M to 980M levels, as our resident Laptop reviewer and UBER-user HTWingnut has already shown in a Clevo P65x series notebook. If youre a tweaker on a tight budget, that would surely be an option for you Just dont cry like a baby, if 980M owners overclock THEIR cards accordingly and still leave you behind in a dustcloud

MEMORY RELATED QUESTIONS​

What is the Max memory this unit can take?
32GB, maybe more in the future, should DDR3 SO-DIMM modules with 16 GB capacity come widely available.

How much memory do I need?
If gaming only then 16GB will be fine, this will support games + multi tabbed browsers and 1-2 VM's. If doing more VM's and or require more processing for design/engineering level applications then 24-32gb is recommended. however we highly recommend 16gb at the minimum, as 8gb is easily capped, rendering you in a throttled state.

Memory speeds? Which is best for me / my usage?
If you're simply gaming and only using your laptop then 1600 is more than likely all you'll need. If you're doing major editing with video and other cpu intensive applications (engineering and more) then 1866/2133 may provide a slight bump. 2400 and higher is more for benchmark results as the difference is marginal. The higher the timings, the more vcore is required to run these, and if you plan on OC'ing your CPU then you will need to take this into account, else you will be dealing with higher than normal temperatures, however this is only if you plan to utilize 32gb or higher. 16gb will be fine @any speed.

Which brand is recommended?
Kingston/Corsair/G.Skill/Crucial/Samsung

HDD/SSD QUESTIONS​

M2 drives, are they worth getting right now?
As with every new tech, M.2 drives, especially the PCIe variety, still sport pretty bad bang for your buck and at this moment in time dont really kick SATA3 2.5" SSD butt. My suggestion (opinions may differ, as with all topics) would be to wait for the Samsung SM951, the Mushkin Hyperion series or similar specced drives that should hit the market this summer / fall. Until then, ull be more than just fine with high-tier 2.5" SSDs

Edit: Eurocom tested SATA / M.2 PCIe 2x / M.2 PCIe 4x in our Batman: http://ift.tt/18JvVxN

I saw the P941 gets temps up to 115C is that real?
This is real and applying a thermal pad may slightly reduce the temps, however those temps were given using insane tests, though the drive itself does get hot. We recommend holding off for the SM951 which will be replacing the XP941 and has nearly double the speeds.

Which SSD is recommended for long term / gaming?
Crucial M series provides great bang for your buck combined with high reliability and very fast performance. If it has to be the fastest, go for either Samsung Pro 850 or SanDisk Extreme Pro Series SSDs.
Also refer to this great article right here: http://ift.tt/1lREHNz

EVO vs PRO?
Ive seen lots of discussion on this topic and my point on this is: In the end, it comes down to personal preference! So check the reviews, ask the user base and build your own opinion I myself have had a great experience with my 850 Pro 1TB and wouldnt wanna go Evo at all, but other people might greatly differ from this stance.

Sandisk vs Samsung I hear a lot about the 2.
Based on performance and many tests, both are nearly equal, most recommend the Sandisk for cost effective reasons, however you will be fine with either.

THERMAL QUESTIONS​

I see that the 4790K gets pretty hot in reviews, is this normal?
Most reviewers use stock thermal paste which is normally applied poorly resulting in higher than normal temps, and also run multiple benchmarks which produce higher than normal real world results ( exaggerated in this case ) If pasted properly one would notice a reduction of at least 5-8C minimum. Please also refer to my overclocking / undervolting guide for more hard data on the 4790K in Batman used in worst-case scenarios (Prime95).

How hot does this unit get under load?
I would be surprised if my 4790K at 4 Ghz / 980M at Stock combo would exceed the low to mid 70s at ALL

How hot does this unit get under load? (normal use)
If by "normal use" u mean web browsing, Office work, Image Editing, etc. then I´d say anywhere in the 60s, not much more.

Does it throttle at high temps? If so how can I avoid this?
Every hardware component has a built-in throttle that kicks in once a specific temperature threshold is reached. Tackling high temperatures can involve lots of things, such as: Repasting / Using high-perf. Thermal Pastes and Thermals Pads / increasing fan speed / Propping up the back of the machine to increase air flow / Undervolting / Underclocking / restricting TDP envelope / regular maintenance and cleaning of heatsink fins and fans / making sure the machine is used in a well-aired and cool environment, etc.

Can I use this in my lap?
Of course you "can" and I´m also aware that this is a "Lap-Top", but seriously? Why would anyone use a DTR on his/her lap?!?!! Just leave the damn thing on the desk and use a frigging iPad or MBP for your lap...! I personally just dont get it... But oh well, everyone is entitled to their opinion

What Thermal paste is best?
Non-Metal based: IC Diamond and Gelid GC Extreme
Metal-Based: CL Liquid Ultra

Gelid GC Extreme vs CLU
GCE is non-metal based, thus doesnt require as much careful handling as CLU, which is metal-based and thus electrically conductive. On the other hand, CLU beats any non-metal TIM, including IC Diamond and GC Extreme, hands down. So in the end, its up to you to decide if youre up to the task or not!

SOUND/AUDIBLE QUESTIONS!​

I've read/used previous clevo's and the speakers were horrible, how does this unit compare to X unit?
Thus far, based on my own experience and other user reports, this machine sports one of the best speaker systems on the laptop market and definitely THE best among Clevo machines But dont take my word for it, ask other users as well!
The only "issue" I could find with the speakers is a slight sound tearing when the volume is cranked up and too much bass is used. Thus, just dial down the volume and bass, and you should be fine

Does this unit have a subwoofer?
No, only the 17 inch version of Batman sports a sub. Based on reviews, that sub doesnt really make much of a difference though...

I work in a quiet room, how loud do the fans get under load? Normal / idle use?
This laptop is DEAD. And I DO mean DEAD! Its unbelieveable, how friggin quite Batman is in idle / normal usage, even in a super quiet room (say, a library), its impossible to make out any fan noise. Even under stressier conditions when the fans finally DO ramp up, the noise they produce is not annoying whatsoever. Again, this is based on my own experience with this, other people more sensible to barely audible noises may differ from this opinion.

WIRELESS QUESTIONS​

Which card is better the Killer1525 or the Intel 7265?
Based on recent results and reviews from others we're highly recommending the Killer1525, HOWEVER if you use Linux then we highly recommend the Intel as linux does NOT support the Killer. In the end, both cards have received stellar and abysmal reviews, so results may vary in both cases!

I've read Killer has issues with connectivity is that still an issue?
Due to recent driver update the Killer wireless appears to be trumping the Intel 7265 as the 7265 has reported spikes in use. These spikes, however, are not reproducible on all configurations and may only pertain to certain applications.

I read that the Killer card is great on wireless but has issues w/ blue tooth?
This has been fixed via recent driver / EC firmware upgrade on Clevos.

BATTERY RELATED QUESTIONS​

How is the battery life?
With such a performance punch and lacking Optimus, dont expect too much in terms of battery life! I was able to eke out 3 hours via undervolting / underclocking / switching everything off / on minimum brightness. More realistic would be 2 hours of regular usage.

Can I game on battery?
You will not be able to play games on battery, it's not designed for that. At best you might get 30 minutes, also expect to have some throttling. Older / less demanding games are of course a different topic. In general, it is not recommended to game on battery, as it puts unnecessary stress on it and thus speeds up its demise!

230W vs 330W which do I need?
230W is sufficient for stock clocks / moderate overclocks on both CPU and GPU (+15-20%) or extreme OC on one of the two (30% and up, most likely the GPU in this case ). If youre planning to tweak EVERY component of your system to its maximum stable setting, then by all means go with the 330W PSU!

I'm Samuel Jackson from "Unbreakable", what does the battery weigh?
Um.....no idea, why does that even matter? Anyone feel free to chime in! *lol*

Can I still OC later if I have the 230W? If so what are my limits?
Since I havent checked it with my power-meter yet, I can only make an educated guess: My 4790K overclocked to its max. thermal limit at 4.5 Ghz pulls around 78W under load in undervolted conditions, so lets say 80W. The 980M is rated at around 100W, that makes a total of 180W. Depending on your configuration, the rest of the system (Mobo, IO, Display, Storage, Sound, etc.) may draw anywhere between 20 and 40W, so that would leave 10-30W of headroom for overclocking the GPU. Since overclocking without overvolting has a near linear dependency of clocks vs. power consumption, that would leave enough headroom for 10-30% OC on your GPU. However, at that level, you would be constantly maxing out your PSU, so I would then recommend switching to the 330W model.

What batteries brands are compatible w/ this unit?
I highly recommend only going with original Clevo parts!

General OC QUESTIONS​

What is undervolting? How do I do it?
Undervolting lowers the voltage input into a specific component, be it CPU, GPU, RAM, or whatever. Benefits are lower power consumption and thus lower temperature without the need to also lower clocks and thus performance. However, extensive testing is necessary to ensure system stability, since too little voltage can make it crash (no harm done though, as opposed to crashes caused by overvolting!)

HowTo: http://ift.tt/1IdGlQ6

Undervolting vs Overclocking? Which is right for me? Pro's/Con's:
Whatever is "right for you" depends on your everyday needs and wants. Best of both worlds would of course include overclocking while undervolting, thus getting more performance at less heat and power consumption! (see my overclocking 4790K overclocking guide, which is a nice example of parallel overclocking and undervolting )
Short overview:
- Overclocking gets you more performance and scales linearly with Wattage and Temps when no overvolt is involved
- Once you hit your Clock limit, but still have thermal headroom left, you can overvolt to get higher stability at higher clocks. But beware, overvolting scales exponentially with temps and power consumption! Thus, tedious testing and careful preparation is needed!
- Undervolting saves you temperature and power consumption without sacrificing performance. System stability might be affected by too much undervolting.
- Underclocking, like Undervolting, saves you temperature and power consumption, but at the cost of performance. This is a viable option for situations where noise and battery life are more crucial than performance.

Programs for testing stability

Overclocking BSOD codes *your best friend*​

BSOD codes for overclocking

0x101 = increase vcore
0x124 = increase/decrease VTT first, if not increase/decrease vcore...have to test
on i7 45nm, usually means too little VVT for the speed of Uncore
on i7 32nm SB, usually means too little vCore
0x0A = unstable RAM/IMC, increase VTT first, if that doesn't work increase vcore
0x1A = Memory management error. It usually means a bad stick of Ram. Test with Memtest or whatever you prefer. Try raising your Ram voltage
0x1E = increase vcore
0x3B = increase vcore
0x3D = increase vcore
0xD1 = VTT, increase/decrease as necessary, can also be unstable Ram, raise Ram voltage
0x9C = VTT most likely, but increasing vcore has helped in some instances
0x50 = RAM timings/Frequency or uncore multi unstable, increase RAM voltage or adjust VTT, or lower uncore if you're higher than 2x
0x109 = Not enough or too Much memory voltage
0x116 = Low IOH (NB) voltage, GPU issue (most common when running multi-GPU/overclocking GPU)
0x7E = Corrupted OS file, possibly from overclocking. Run sfc /scannow and chkdsk /r

DELID SECTION
WARNING this section is for advanced users ONLY! If you are unsure or have never touched your hardware before you should seek professional help (hardware personnel NOT Dr's!)as this could permanently destroy your CPU.​

What is Delidding?
Modern CPUs have a so-called IHS or Integrated Heatspreader on top of their CPU dies. As the name suggests, this heatspreader evenly spreads the heat onto a larger area for the respective CPU heatsink to suck up and get out of the system. In the "olden days", Intel soldered the CPU die to the IHS and thus heat transfer was very efficient. Starting with Ivy Bridge though, Intel cut costs and exchanged the solder for regular thermal interface material (TIM) / thermal paste. The idea of delidding is to remove that IHS, exchange the TIM with a high-performance paste and then either reinstall the IHS or run the CPU "bare die", thus with direct contact between the CPU die and the CPU heatsink.

Delidding Guide
See this link for more information:
http://ift.tt/20xAMYZ!

Why CLU?
Generally, Coollaboratory Liquid Ultra (CLU) is the preferred TIM for delidding projects, since it sports the very best thermal conductivity. Due to its metal-based nature and thus inherent electrical conductivity, handling CLU HAS to include the utmost care and tedious preparation!

Known issues / fixed etc​

Coil whine
Has been verified in various units, however does not cause any issues other than small noise in quiet rooms w/ no sound. Also affects units arbitrarily, some (like mine) have unnoticeable whining sounds, that ure only able to hear in a dead quiet room when you glue your ear onto the chassis. Other cases have been documented with far worse pitches / volumes. As with everything else though, it also highly depends on the sensitivity of the respective user to such noises. For videos and sound samples, please refer to the respective posts in this thread.
Additional info from mySn/Schenker rep:
"We have had a report through from the RMA department regarding coil whine in this model and the 17" version. As you may be aware, we have been working with Clevo on this to help them resolve the problem and have passed a lot of information to them as well as chassis for them to test. Now that the MB revision is available the issue should be fully resolved. The Nvidia GPU buzzing is a separate issue (which Nvidia do not acknoelwsge a problem with) and there is also a rare problem with buzzing through the speakers that we are also talking to Clevo about.
For now, I just wanted to pass on our official RMA rate of the P75xZM and P77xZM due to coil whine, which is 0.8%. I can't give you the number of chassis that we have sold for obvious reasons, but it is based on a rather large pool of data.
Our hope is that it will instil a bit more confidence in the laptop models; though there may be a handful of customers on nbr that have said they have issues the actual percentage of owners who have experienced coil whine is below 1 in 100!"

Flimsy / Wobbly screen
In order to make this machine so powerful, but at the same time comparably compact / thin, the screen lid was designed to be thinner than in previous Clevo performance models. Some users have expressed worries, especially concerning frequent travels with this machine in combination with packed suitcases / backpacks / etc. Although I myself have noticed that, compared to previous laptops Ive owned, I´m more careful on how I place my Batman and what I put on top of its lid, as with every expensive piece of tech equipment I suggest: Careful handling, regular maintenance and lots of luuuuuuv! I dont find the screen so delicate as for it having the risk to fall apart by just using it in a regular manner.
Following these simple rules will make you a happy camper indeed, just dont be surprised if it cant handle being packed in a maxed out suitcase / backpack being placed under tons of other stuff Absolutely NO laptop should find itself in such a situation!
