P750DM2: Project to keep it alive.

[anassa]

Hey all,

 

So I have a P750DM2 that I am going to update to last me a couple more years, and I thought I might as well post the tests and results to help others that might want to keep a 2016 laptop relevant!

 

When I first bought the P750DM2 (was an Origin Eon15? ) it had a 7700k and 1070 GTX. I will have to check if I have benchmarks from back then, but I am starting it with the following baseline specs:

 

CPU: 8700k delidded with copper IHS

GPU: 1060 GTX

RAM: 16GB Crucial 2400Mhz CL17

Drive: WD Black SN770

PSU: 330w

Heatsink: P750TM for CPU / P775TM oversized for GPU, not unified

Thermal Paste: Thermal Grizzly - Kryonaut

Nvidia Driver: 546.33

 

For fan control I am using RLECViewer with the following fan curve for both CPU and GPU:

40F/20%, 45F/25%, 50F/30%, 55F/35%, 60F/45%, 65F/50%, 70F/60%, 75F/75%, 80F/80%, 85F/90%

The "F" is the temp and the % is fan speed percentage.

 

I will run some really simple test between CPU differences, namely 8700k and 9900k, difference between HT on and off, cooling upgrades/changes, RAM, and of course different GPUs.

 

Some of the general performance for different combinations can be replicated in the P7XX and P870X models so it may be interesting for more than just P750DM / P750DM2 / P750TM / P751TM owners.

 

I only have Cyberpunk, Metro Exodus, Timespy, and Cinebench R20 for benchmarks to see what changes had what kind of differences.

The benchmark does 3 runs on a scene

At 1080p

Settings: Very High / SSA - ON / Texture Filtering AF 16x / Motion Blur - Off / Tesselation - Very High / Vsync - Off / Advanced PhysX - On

 

Timespy GPU Stress Test:

Frame Stability: 98.60%

Max GPU Temp:  77C

Max CPU Temp:  83C

 

GPU Setup: 1080 GTX , AliExpress heatsink, P775 fans both sides, repaste,  Undervolt Curve +75/ Mem +300

CPU Setup: 8700k / -100mV offset, 6core 4.4Ghz instead of 4.3Ghz / HT Off

 

 

 

*Max power consumption was used from HWinfo, not otherwise specifically measured.

*Sometimes I forgot or did not do a run on a setup so have I "------"

Green = Best Number

Orange = Worst Numner

 

Baseline settings:

• 8700k set with -100mv undervolt and 6 core Mhz set as 4.4 instead of 4.3.  So even at the start I have already undervolted the CPU.
• 73F ambient temp

 

GPU OC

• Same as above 8700k settings
• GPU had a simple +50 core and +350 memory.  Not a fined tuned OC, just a easy one that anyone could do.

 

RAM 3200 swap

• Same as baseline CPU 8700k settings
• Same GPU OC as above
• RAM was swapped from DDR4 2400Mhz CL17 to 3200Mhz CL16 and now 32G instead of 16G

 

HT Off

• Same 8700k settings / Same GPU OC / Same 3200 CL16 RAM as above
• Only Hyper Threading (HT) was turned off in the bios

 

1080 GTX swap

• 8700k 100mv undervolt and 6 core Mhz set as 4.4 instead of 4.3
• Aliexpress heatsink for P750
• P775 fans instead of P750, P775 has more fan blades
• Repaste obviously
• 1080 GTX stock curve

 

1080 GTX OC / HT Off

• 8700k same settings with HT turned off
• 1080 GTX had a +75 core for the curve with 0.925v set as undervolt and +300 memory - also not fine tuned, simple repeatable for most 1080 GTXs

Observations (so far):

• RAM speed upped my Timespy CPU score by ~700! I was surprised that going from 2400 to 3200 had such an impact.
  • But for the two games it didn't seem to make much of a difference, bottleneck is elsewhere?
• Turning off HT didn't really impact the FPS for either game.
  • This was for both GTX1060 and GTX1080 at 1080p
  • Obviously shows bottleneck is elsewhere? Otherwise there may be a difference?
• Swapping from 1060 to 1080 had an obviously noticeable jump in FPS
  • CB2077 went from avg FPS of 33 -> 76 (for high preset with no scaling at 1080p)
  • Metro went from avg FPS of 48 -> 80
• Aliexpress Powerups heatsink can manage a 180w GPU in a 15.6" clevo! (given a ~70F ambient temp)

Good work, a lot of time was spent to obtain this data!

Never got the 3070 working well - will get back to it eventually - but instead found a 2080 RTX for cheap.

 

The wonderful thing is that bios sees it, so no modified drivers are necessary.  The scores are also for basically default without any tweaks so I am looking forward to seeing what I can get out of it.  Cyberpunk already sees around a 12FPS gain which is very nice!

 

Best part of it is that P750DM2 came out late 2016, 8700k came out in late 2017, and 2080 RTX Mobile came out early 2019.  But it all works together with only a bios update (dsanke BIOS). That is the wonder of laptops with socketed parts!

 

[anassa]

Got the 8700k better dialed in:

• 4.4Ghz 6 core
• 4.6Ghz 4 core
• 4.8Ghz 2 core
• -140.6mV Core and Cache undervolt

For CineBench R20 was able to get my highest score so far: 3,468.

And for Timespy CPU score was able to get 8,008.

 

It is a bit toasty at around 85C with an aggressive fan curve. But not bad as it doesn't have a cooling pad or anything below the laptop to help keep it cool, just the P775 fans and Aliexpress heatsink.

 

Also overclocked the 2080 a bit +125Mhz Core and +450Mhz VRAM adding the cart below with new cyberpunk and metro benchmark numbers.

What I found interesting is that even with the GPU bump the AVG FPS in Cyberpunk stayed at 88FPS, but the MIN FPS went up from 70.56 -> 74.52.  On the GPU side with the mild overclock the graphics score on Timespy went from 9,656 -> 10,127 with it seeming to have more headroom but thermals not really allowing me to push it higher, this is also only pulling ~150w. With the 1080 previously I was able to pull ~190w without hitting the thermal limit, so I wonder if my contact between the heatsink and GPU die isn't as good.

 

But still - a RTX 2080 from 2019 can do 1080p on High graphics settings, on a game that is modern and amazing looking, at close to 90FPS average. Sooo . . . these "old" Clevo laptops are still very relevant!
