You could use it as a separate drive but you would not be able to use it to accelerate a hard drive as that requires Z270 chipset.

Apologize if this has been asked before, but is there a way to turn off dGPU and run on Intel iGPU to get more battery life?
Perhaps via BIOS option or Clevo software?

 

No, the IGP is not wired up.

 

new case: i need intel HD for only encode/decode H264 media project - no need any wired up.
can i enable intelHD ???

 

None LGA speced notebooks can enable Intel graphics. Neither the Msi Barbones or the Clevo’s.

 

The dGPU should be able to assist however.

 

love the bit about the curtains! mine squirted across the room and hit the cat!

 

It takes a minute amount of liquid metal, even if you put 3/4 of the smallest tube over the curtains there should be plenty left.

 

really think pcspecialist ought to be!

 

They have always been a play by numbers kind of reseller, they don't tend to make changes like that.

 

Hi,

I tried 2 heatsinks (First link and second link).

With the original heatsink I got 10°C difference between CPU and GPU at full throttle. With both I get same temp from idle to full throttle. Temp increasing is lower than before, up to 70°C CPU and GPU (Prime+furmark). The heatsink from the second link is bigger (17") than mine (15"), so I can't close my laptop casing. With first one it's OK.
I7 7700T and GTX1070

I have a question. My CPU is normaly runing 2.9Ghz 8 threads, 3.6Ghz 4 cores, 3.7Ghz 3/2 cores and 3.8Ghz one core.
With all my benchmarks I got 3.6Ghz one core, 3.45Ghz 2/3/4 cores, 2.4Ghz 8 threads. Someone knows why is it lower? Maybe somewhere in the bios there is something to check.

Thanks

 

This is an 35w locked down chips https://en.wikichip.org/wiki/intel/core_i7/i7-7700t
See if you can undervolt (Use Xtu or ThrottleStop) for lower power consumption to keep higher clocks. 2.4GHz is very low. You get this clock speed in Cpu benchmarks? Try whats suggested + put High Performance in Win power plan. Run Cinebench R15 benchmark before and after undervolt. Post pict with scores https://www.maxon.net/en/products/cinebench/

 

Hi Alfly, not sure what's going on there! i don't have that particular cpu ? but follow Papusans advice, he knows a lot more than i do! in these matters, sorry i couldn't be more helpful.

 

Hi guys.

Thanks for your answers.
It's a small CPU yeah. I chose that for some reasons. Impossible to overclock, I tried quickly just for fun.
I will follow advice and try to undervolt. I tell you the difference when it's done.

 

If you could play around with the TDP at all that would be the biggest factor, undervolting will help too.

 

Intel(R) Speed Shift Technology is good or not good ?
why clevo default disable and hidden this option on BIOS ?

 

Yes it's disable stock, I actived it. Checked in XTU, and it's OK.

I don't think I can change the TDP with that chip (eco I7 chip) My max TDP is 45W during 8s before falling to 35W. Maybe I can try to change "Turbo boost power max" from 35W to 40W for example.

Anyway, I can try all the ways. I will do that with Intel XTU.

I finish the OC and UnderV of my 1070 and I start to fix the CPU.

 

You could try ThrottlStop as well if XTU won't help. The settings for Power limits is in the TPL window. How to Lower Temperatures, Stop Throttling etc with ThrottleStop

FYI. You have also access to Speed-Shift in ThrottleStop.

 

If you can extend the turbo window you would be able to remain at max clocks longer.

 

Will Samsung 970 EVO 250GB NVMe work plug and play in this laptop or will I need to do something before?

 

It will work just fine, do you want it as a boot drive?

 

Yep, NVMe as OS drive, secondary regular SSD for games.

 

Hi !

So I did the underV. -150mV Core voltage Offset and Cache voltage Offset. The CPU can now go up to max frequencies. I have no temp gain or just 1 2°C.
My cinebench score: Here

 

+rep
Nice increase I don't know if you run Cinebench R15 with antivirus, Hwinfo + other software in the background. If you did, expect higher scores if you diasble it

 

You are right, I have a lot of apps in background and HWinfo.
I have to check if it's stable in game. I tried -160mV and it's working but I saw nothing really better, so I came back to -150.
I OC my ram also at 2666 in place of 2400. At 3000Mhz my laptop crashs and doesn't start.

I wanted to do by myself in the bios but nothing called "Ring" or "Cache" for the Cache core voltage. My premamod bios looks like differente than in Phoenix's videos. So I did all with XTU.

 

samsung EVO 970 will work ok, you may need to download samsung magician and update drivers

 

I am interested to know the boot time with that NVMe, and the difference in game (during loading).

It's one of the NVMe I would like in my Clevo (970evo or 960evo)

The booting time with my cheap Intel is good, but the loading time in game not. It seem my NVMe is idle in game, so maybe update to the Samsung will do nothing more.

 

The normal user like yourself wont notice the difference from SATA.

 

I owned 2 Sata. One Samsung 840Pro and one samsung MZ something in M.2 sata. The first ran to 540Mo/s (read and write) so I saw no difference with my Intel 600p nvme (1500 read, 600 write). But with the samsung MZ... M.2 (600 read, 150 write) I saw the difference in game and to start my computer.

But it's possible I feel any change between Intel 600p and 970evo.

Edit : Not a Samsung Sm, but MZ

 

Not the best NVMe ssd out there... The Intel SSD 600p (512GB) Review - AnandTech

 

Not really yes.

 

When looking at per cost you can usually get a pair of SATA drives, in Raid 0 the 850evo and my SM961, I really can't notice the difference.

 

So some days using that undervoltage. I tried to push more, -180mV crash directly as -170mV not enough stable, -160mV stable to work but not for gaming. I stay at -150mV that is not so bad for now .
My cpu is running all the frequencies except with 4cores which need 41W instead of the 35W of my CPU (Using Prime95 on Max consumption test) (45W for 8s).
Edited post.

I change my TDP to 41PL1 and 51.250PL2 (8secs). 30 minutes prime95 and furmark, all ok, temp 67CPU and 72GPU. I know it's not representative of games but it's my reference between each change for temp.

This is a "strange" CPU for a gaming/worstation laptop, but I wanted to try this configuration.

 

It is strange but there is always a niche and the socket gives you that choice.

 

If the T can keep "cool" my laptop without additionnal fans I am happy even if I haven't the power of the K. Same thing about my 1070 instead the 1080. The problem is : I find any real infos about this CPU, even on google. Laptop gamers want a powerfull PC, and desktop users don't care about heating, nobody wants this CPU.

 

Its meant more for small form factor media pcs and the like typically

 

Hello everyone!

I am new here as a user, but visited this site a lot, from here I first found these great laptops with desktop CPUs!
My model is P751DM2-G, i5 7400 and GTX 1060. Recently upgraded to 1080 and it is a huge improvement in performance but with higher temps though and nVidia drivers mod. I got this model as second hand in great condition and want to upgrade now the CPU to a Coffee Lake. It comes from PC Specialist UK (boot logo at least).

Has someone upgraded P751DM2 with a Coffee Lake CPU? I know that there a BIOS and EC update is required, at least this is one for P870 model and isolation of several CPU pins. Now I am standing in buying between the 7700K or the 8700K, if someone can help me I would be grateful, it is a important decision for me to make.

In the meanwhile, as I also like good sound from the speakers, I added the missing components in the sub-woofer circuit, built up a small sub-woofer of a size of the 2.5" hard drive and it is mounted on the hard drive itself (on a SSD actually). It now sounds much better, but still I have to make the laptop a little higher because the speaker is a little high, the hole for the speaker itself in the bottom cover. I will post some pictures later.

And, I want to integrate heatsinks from the P775TM model, add extra heatpipes and integrate watercooling if I succeed with the 8700K CPU
There also a little case mod will be required, but it is doable, at least I want to find both bottom covers to mod.

 

The 17 inch uses larger heatsinks, you will need to modify the chassis and have them sticking out. You are pushing with the 1080, the 8700k is going to add to the thermal/power load significantly.

 

I am aware of the chasis mod. What about the new heatsink used in P750TM model? Does this one peform better than the original one (3 heatpipes on the GPU instead of 2)? This one:

https://www.ebay.com/itm/new-for-Cl...237163?hash=item2857e3c6ab:g:nioAAOSw30Ja~pm~

Adding the 8700k is for extra cores and it's very amazing to have it inside this little machine, so if possible to mantain it at 80C under heavy load will be acceptable. The main reason for separate heatsinks is that I can add or remove a thermal bribge if necessary, some aluminium vapor chambers, though I don't know how these perform:

https://www.ebay.com/itm/100mm-Widt...2a:m:miuti89x6eIA-K1zWPQGGgA&var=690465762992

Adding a extra heatpipe on both heatsinks to be total of 4 might give a little advantage, I also thought about vapor chambers for both CPU and GPU, but did not found anything yet, desktop cards have them a little too big and mounting holes cannot fit.

Is there a way to change harware ID for the GPU to be able to install drivers without .inf mod? Also the GSync is gone because of that..

 

G-sync is not validated on the 8086k so that's what will be doing it.

The one you posted is a balanced design.

 

Which is the best place for a single NVMe drive? The upper one or the lower one (located near the two 2.5'' sata slots)? I'm asking this in terms on cooling.

Edit:

After some test looks like the upper one is clearly better place, like 10ºC less in that spot.

 

More airflow around there, so yes sounds right to me on the upper slot.

 

I also have noticed that I have no video output from mini DP after upgrade to GTX1080 and .inf driver mod. It does not detect any monitor, tried several dell monitors.
Is there a specific hardware ID which should be choosed from the list when moddig the .inf files?

 

Have you tried a pre-modified inf from laptopvideo2go.com? (go to the forum)

 

Not yet.
Which driver version I should use? 398.46 is OK?
I have installed 388.XX version for now.

Offtopic: can anyone point me to the asus rog laptop upgrades advanced forum? I have a g53s build entirely from pieces and got stuck with video card (gtx 670m and 560m standard MXM) not willing to boot into any OS. sorry for the offtopic

 

Not much going on these days but see the Asus subsection.

 

Spend a lot of time with this asus, many bios and vbios trials and all go failed.. not much tools and knowledge in this area.

What I learned is that changing HardwareID is a good option, might be useful for my GTX1080, but I am not sure to which ID I should set it.. probably to the one used in P750TM model just to be able to also have the gSync back? Panels also should match for this but mainly for the drivers to match a valid ID.

Is there any premamod BIOS and EC for P751DM2-G model? I haven't seen yet one to support as well the 8th core i series.

 

Yes there is but not publicly available.

 

As I like this laptop and the good sound, the lack of a subwoofer in it was too bad so I thought I can make one.
First of all found the schematics for this model, inspected it, found all the electronic components for it.

Before the motherboard was: ​

The last step, soldering the audio amplifier cip:​

The electronic part is reay, (also there was soldered a 2 pin connector for the subwoofer)​

The sobwoofer, made it to be mounted on the SSD case (the hard drive can't be used because of the vibrations) :​

And in action:​

All it's left now is to mount it in case and install a nice looking sieve, still looking for spare bottom cover for that...
It now sounds like much better, I don't know how a p775 sounds to compare both.

How can I get BIOS and EC firmwares latest premamodded for P751DM2-G model? I am not sure how to obtain them

 

Very cool mod, nice work The prema mod would have to be requested nicely from himself as it's not publicly available.
