i actually did a small test of comparing my SM951 m.2 NVME via my Sandisk Extreme Pro 2.5" SATA which i use for my main games. I did it with Guild Wars 2 cause @Omnomberry asked me if i could do a comparison. Used different characters cause they were parked at different locations.
I restarted the NB after every test to be sure everything is somehow wiped from cache which could lead to wrong values. I waited exactly 10 seconds in the character selection menu and pressed "enter" to login which of course started the countdown.
Sandisk Extreme Pro -> Warrior login to Lionsarch sec 10.48
SM951 -> Warrior login to Lionsarch sec 8.87
Sandisk Pro -> Necro Divinitys Reach sec 8.40
SM951 -> Necro Divinitys Reach sec 7.28
Sandisk Pro -> Ele Caledon Forest sec 7.06
SM951 -> Ele Caledon Forest sec 6.37
About 14% Difference
so as you can see in this MMO it was a very minor improvement about loading times, i think we need more 4k read performance to really load faster.

Looking at the service manual you can use both at once at full speed x4 i.e the lanes aren't split between the two M.2 slots.jpsm likes this. -
Also do you have any idea if the 230w power adapter for my system is enough? I read that the cpus power consumption is 83w and the gtx980m is at 122w. Total of 205 for both components alone. -

230W is fine for stock, I use a pair of 500GB EVO drives in my own system and they have been rock solid for me

Just for my own curiosity and understanding would you be able to explain a bit further? I'd love to have a firmer understanding on this. I had a reasonable grasp when it was northbridge/southbridge but I haven't got my head around this yet.
I can see that Skylakes DMI 3.0 operates at x4 with total link speed of 3.93GB/s so I am curious how this is split between these components.
It's stated that (at the very least!) using one M.2 PCIE slot it will operate at x4. I understand no SSD can saturate that link currently, it's fair to assume in the future they will though. With this hypothetical drive would that x4 link then cause slow downs on USB 3, Ethernet etc while it is being fully utilised?
I didn't think DMI channels could be shared simultaneously, or is there some kind of multiplexing involved or is there another intermediary interface that I'm oblivious to?
How does the 40Gbit/s (5GB/s) thunderbolt port fit into this when all 16x PCIE lanes are straight to the MXM slot?god1729 likes this. -
Anyone know whether HDMI port is 1.4 or 2.0?

The trick here is to think of the PCH almost like a completely separate system (imagine another motherboard). The Skylake PCH has 20 PCIE3.0 lanes to talk with everything.
In the case of Z170 and what we're looking for, PCIE lanes 9->12 are connected to M.2 port 1, lanes 17->20 are connected to M.2 port 2. PCIE 13, 14, 15, 16 are connected to WLAN, eSATA, SATA1 and SATA2 respectively. PCIE lanes 1->4 go to Alpine Ridge (ie USB3.1/TB3), 5/6 appear to be unused and 7+8 are for lan and card reader (aw yiss, PCIE card reader instead of USB...for reasons?)
http://www.samsung.com/semiconductor/products/flash-storage/enterprise-ssd/MZPLK6T4HCJL?ia=832
6000MB/s sequential reads and 1million random read IOPS means it has to be on a x8 card.
The fact that DMI bottlenecks things is already well known (many have already tried RAID0 with 3 NVME drives and found the sequential speeds cap out). However, I haven't found anybody who has tested what actually happens when you begin taxing other DMI attached hardware.
To be honest, I have no idea why all 16 CPU PCIE lanes are channeled into the MXM slot given that a modern GPU doesn't really even tax 8 lanes. This may be an Intel thing though as they describe the CPU lanes as specifically for "GPU" in desktop systems. The P7X0 is essentially a "desktop" as far as hardware is concerned after all. It may also be allowing for future GPU development. Particularly, HBM could have a rather large impact on how quickly you need to get textures from our now super-fast SSDs/RAM to the GPU.temp1147462323 and stonetrap like this. -
Hi everyone. I don't own this notebook but I'm seriously considering buying one. I intend to do a lot of gaming and video editing on it. I was wondering if anyone here has this model with the 4k screen and 970M and would recommend it for my purposes. I've read differing opinions that the 970M on this machine cannot handle gaming in 4K and people just scale down to 1080p to play their games. If this is true, should I just get a 1080p screen?

It seems I tripped up with knowing there's a total of 20 PCIE lanes, 16 of which are GPU, I couldn't envisage the remaining 4 being split, yet still being able to offer x4 to a single M.2 slot while having other lanes for WiFi, card readers etc. Your explanation of DMI has really cleared that up. Thank you; envisioning as an encapsulation route brings that together.
I have looked at the Cougar Point circuit diagrams in the service manual, it was those that made me believe x4 could be offered to both M.2 slots as electrically they are both configured that way, and there's no mention of in there of the capabilities of DMI in there.
Anyway I won't further derail this thread.
On an entirely unrelated note.
Does anyone have any experience with an RMA through Clevo Germany (GoldenStar Computers). They've had my laptop a couple of days and I've not heard anything, even as much as acknowledgment of receiving it. Just wondering what sort of time span is typical and if I should expect contact from them or my reseller (Eurocom)? -
I suspect Intel were completely taken by surprise with how quickly PCIE got flooded with fast devices. USB3.1, Thunderbotl3 and NVME SSDs pretty much all went to market in a single year.
The real test will be when egpu enclosures actually arrive. -

Quick question, what's the oc value s need on the 980m to match performance of the 970 desktop card. Should that be enough for VR on the 750dm?(titles tuned for the 970, not necessarily long term VR)
EDIT: can the 970m achieve this as well?(values?)

Is there some sort of guide or bible or glorious post about overclocking the P7x0DM?
I mean, most of us are rocking the same config: 6700K + 980m, are there a couple settings that have proven stability and performance?
Is Intel's XTU the way to go for all things overclocking? (For the CPU at least)
I've read a lot about undervolting and I think it's probably the way to go if you are not too serious about modding the heatsinks or IHS
Thanks!
By the way: I think I finnaly figured out what the hell was causing my random crashes on Windows start.
As I said a few pages ago in this thread, my P770DM-G was displaying nothing but a black screen and HDD activitiy when turning on. And because I had a new cooler base/USB hub (with keyboard and mouse connected) + USB DAC + Second monitor via DisplayPort I though that one of these would be the culprit.
I formated my PC and reinstalled Windows 10. I had a week with absolutely no issues. But sometimes when the PC woke up from sleeping a long time it would display a "Returning from Hibernation" message. I already have hybrid hibernation turned off thru the control panel so I figured I would input powercfg -h off into the console to fully disable it.
Boom! The crashes came back! PC wouldn't even turn on again without some major trouble....
powercfg -h on back in the console and everything is back to normal once more!
Turns out the P7x0DM really don't like anything to do with hybernation...
I'm on stock BIOS BTW, is this issue addressed in the new version?Last edited: Feb 26, 2016 -

Overclocking is a lottery, so there will be no magic figure for everyone (otherwise intel would set the clocks there).

Delid with liquid pro inside, gelid extreme outside.
My p750dm-g is rock stable and has proven to be by passing linx 0.6.4avx 20times with [email protected].
As meaker said, OC is lottery but now with stock bios you wont be able to OC well enough because power limit is locked at 53W.
This damn low power wont allow the CPU to hold the clock with heavy load when OCed. My p750dm-g with stock (but Korean Stock) bios has power limit lock too but luckily at 118w which allowed me to successfully OC 6700k at 4.5 with -75mv.jpsm likes this. -

Vbios has nothing to do with CPU. Vbios is just video-bios.
I am talking about BIOS for MOBO.
There are many BIOSes for p750dm. I've tested clevo stock, XMG stock and Korean Hansung stock.
Both clevo and XMG allowed memory OC but long power limit is locked at 53W which is very low for 6700k. At stock clock 6700k will be okay but if you are planning to OC, 53W is too little.
On the other hand, Korean stock bios doesn't allow memory OC but the power limit is capped at 118W which I dont like too but at least this power allows my CPU to be OCed at 4.5 successfully at -75mv.
I preferred to have a OCed CPU /w non-OCed memory rather than non-OCed CPU /w OCed memory. That's why I chose to use Korean stock Bios. -
@Meaker@Sager
I heard you work for Sager. That's cool!
Do you know the max power allowed on p750dm-g stock bios for Sager?
Is it also 53W or something?
And if you can, can you please tell me the version of HDMI? (1.4 or 2.0)
Thanks~!Last edited: Feb 27, 2016 -

Max power for what exactly?
HDMI 1.4b for the output. -

Hi guys i have got p751DM for testing and have one question
When i oc i5 6600K to 4.4 ghz it works good in xtu bench, stress test and cinebench r15 but after running 3d mark firestrike it locks itself on stock 3.5 ghz on 4 cores in xtu while profile is set to 4.4 ghz...
Am sure there is any thortling all 4 in xtu are on 0.
Owner demanded windows 10 for testing
Anyone suspects what is going on?
Also i have tried to dind multipliers in bios but stock clevo is sparseAttached Files:

Having the 6700K at 4.5Ghz with -75mV, how does the cooling system perform?
Thanks! -

Change Turbo Power Time Windows to 1 second
Set Processor Core ICC Max to 130A -
(Only Korean stock works that way, but capped at 118w and 123A)
We need prema! -

This is the link for the Bios.

This is "how to flash the bios" manual. As you can see in the picture, disable UEFI and boot to DOS mode with USB containing only the bios files.
Then press 1. Wait for some secs and the laptop will reboot. Press F7 to boot to DOS again and press 2.
Bios flashing is always with risk. No one is responsible for bricking so please do it at your own risk.steberg likes this. -
The temp will depends on several things.
Mine is delided with liquid pro inside and gelid extreme outside.
I've found the optimal lowest voltage by testing stability with linx 0.6.4avx and the voltage was -75mv for my 6700k.
The max CPU temp during 3dmark's "run primary tests" which also runs demos is about 83C with fan table "overclocked" and 77 with fan table "max".jpsm likes this. -
Thanks for the answer. Damn I thought it was 2.0 -
how much more battery time can you squeeze out of this system with undervolting the cpu and dgpu?

There are three fan tables (win10) which are automatic, overclocked and max.
I usually use "overclocked" fan table. -
with my i5 well xtu stress test 4.5 ghz is rock solid but during firestrike and later in xtu stress test cpu returns to stock frequencies while all settings are set to 4.5 ghz... without some korean or prema BIOS you probably will have same cpu behavior as me. -

I had similar problems.
I fixed it by not using XTU and using TS instead.
