*** Official Clevo Sager NP9155 / P750TM-G / P751TM-G Owner's Lounge! ***

I have the 1.07.28 version. I think it's unlocked because it Lets me change the board voltage. The EC version Is 1.07.16

 

hi everyone,

are there p751tm1-g owners that have done some dpc latency tests?
I would like to compare results as I'm having trouble with dpc spikes from acpi.sys (around 500us and occasionally higher)
and a few others wdf01000.sys ntoskrnl.exe etc.
tried every optimization possible updated all drivers and tried various bios settings.
im trying to get as low as possible audio latency from my system.
96khz with a 32buffer without dropouts( resulting in crackles pops etc)
curious to know if anyone with a premamod bios have lower dpc latencys.

 

Have you tried using windows timer tool and set the refresh to 0.5ms? Disabling spectre/meltdown with inSpectre? Fixing the windows QPC timers?

 

hi denton,

tried the timer tool but it seems it wont stay on 0.5 ms setting.
after seeing this video i know why.
gonna try these options right away.
thnx and ill post if that solved my problem.

 

So I've been on the hunt for clevo rtx 2060 cards and they are practically impossible to find I've tried everywhere, I'm very tempted to just buy one of the mxm to pcie adaptors and have an external graphics card but was wondering if anyone has tried this or not and if it's worth the effort?

Well there is one on Ebay Germany, used. U can give it a try and see.

What are you running now?

 

A gtx 1060 atm

So the above is the internal option at that point, it will be interesting to see if the 3060 is going to fit. You'll need a heatsink.

 

Should I get a new heatsink?

Also I mean 2060 right? Unless there is a 3060 mxm which I highly doubt at least yet

I am talking about both the linked 2060 and the 3060 in the post.

 

Sorry I have no clue where your post is mind linking me it?

The post about the 2060 you had asked about on German ebay.

 

Ahhhh my bad most likely gonna grab that one if I can I hope it works out fine

i assume next gen ampere cards will be compatible with the x-170 if thats the case then older p750tm1 p775tm1 could fit them aswell? lets hope they still use the 150w tdp

 

It depends on their physical layout mostly in case there are new vram layout requirements and that sort of thing. If it fits physically then chances are good it can be made to work.

 

Hi! I have a P751TM1-G, and i would like to know if it was really useful to delid my i7-8700K?
Thanks for this topic, and sorry if it was already asked here.

 

i just disable turbo boost and i still get smooth gaming experience without dips, temperature wise the laptop runs about 20 degrees cooler, i have ran the division 2 benchmark with and without turbo boost and FPS average remains the same on both , i dont care about synthetic benchmarks or productivity

 

I did it to my 8086K, with liquid metal all around and a taller heatspreader it made a big difference.

 

A taller heatspreader? Where we find this?
by the way, I think that i'll do this when I receive my DDM2, with Conductonaut/high temper silicon.

Also, i have an interrogation. I tryed to do an optimization (0.96mv override voltage, offset 0, and 4.3Ghz on alll cores. it was very nice, i winned 8-10°C in stress test without delid/lowering his performance) with my 8700K, based on this : https://overclocking.com/wp-content/uploads/2018/04/Core-i7-8700K-Overclocking.png, founded here : https://overclocking.com/test-intel-core-i7-8700k/15/?amp=1 (i'm french, so this website is in french, sorry)

But when I restart it, the start is looped. Thanksfully to the combo FN + D with power button (sometimes I had to do it several times, to access the BIOS and set the basic values), he dosen't have anything. ^^
I'm trying this tension optimization with the CPU overclocker of Control Center v5.0001.1.97. I don't know how to do the same directly on BIOS of my P751TM1-G... (bios version updated to 1.07.29)

Thanks, beforehand (and sorry if it was already posted a similar case of mine)

 

I had a silver shining IHS for the old cores that I modified to fit the new ones but I did see some bare copper taller ones iirc.

 

Send an email to Rockit cool or https://bartxstore.com/product-category/standard-cooling/

 

That's the one

 

Sadness, all the "Intel 8xxx series Custom Copper IHS for Clevo" from this website are out of stock

 

You can reach out to BartX and ask for for 4.37mm custom IHS, https://bartxstore.com/

 

Thanks, I'll check this.
And having an idea for how I can put my 8700K on @4.4Ghz, and set a good adaptative voltage with this?

 

Test it with something like cinebench r20/r15 or a stress utility to find where your chip bottoms out by lowering the offset gradually until it crashes. Usually by 5-10mV until instability arises and then set it 5-10mV above that threshold.

 

Thanks!
With 4,4Ghz, at 1.01v (1.25v with -240mV) all works fine, but at 0.95v it crashes. So I set it to 1,01v.

 

Adjust it upwards by 5mV until its solid, should it crash in games using AVX.

 

With that parameters, in idle the CPU temps are around 40-45°C, and in CPU-Z bench/Cinebench R15, so full load, temps are reaching 73°C, on maximum.
Its very okay! And that, without delid/repaste or nothing, with stock paste. Before that, when CPU was benched, it reached over 80°C on moments.

 

It's a nice amount of headroom that's for sure.

 

So, after delidding, repasting the die / IHS with Conductonaut, cleaning the fans (there were very few dust), setting the "mod" for the radiator with paper clips for the GPU and toothpicks for the CPU, and finally repast of my 1070 / 8700K with MX- 2 2019 edition; its the time for some results!

For the GPU, without any changes (stock, 40°C in idle) I reach 67°C at the FurMark 1440p preset (75/80°C before).
For the CPU, I overclocked him even more (@ 4.6Ghz, 1.08v, 40°C also in idle) and everything is stable (Cinebench R15, CPU-Z (with AVX or not) ...), and I reach 76°C maximum. Always less than with the original clocks, before (80°C).
It's not a huge change, but it's really good for me!

Now, it rest me my SSD (960 Pro M.2); i dont know how i can cold him... in stress test, it reaches easily his thermal throttle (70°C)... I put on him a thermal pad (without his rad), but it dosen't really change in fact. And I don't have a laptop cooling pad. :/

 

Then leave a little headroom.

 

It's all trial and error until you find that balance between stability and performance.

 

Samsung 960 pro and 970 pro run crazy hot. Do a CrystalDiskMark test with HWmonitor open and behold the furnace that is the controller chip.

 

Just keep in mind that with really tight headroom you will go slow chip degredation over time eating away at any margin.

 

Everything degrades, just a matter of how fast. Temperature, voltage and amps just speed up the process.

 

But with really tight tolerances even a little degradation could push you over.

 

Nothing lasts forever.

 

so question to all

@Meaker@Sager @Donald@zTecpc @Mr. Fox @Prema

would temps be better in my p751tm1-g if i change from a gtx 1080 to a rtx 2070 , is the much difference , in temps , in the fps , and all , i currently i am running with a i9 9900k delided ,and under volted -100 , any pointers as i have a chance to buy a new rtx 2070 at a nice discount currently please give any and all advice ...


also how do i tell if i have a desktop model of gpu or mobile 1080 , is the a model number i need to look for under gpuz????

 

The performance is a wash, but the 2070 has ray tracing and DLSS support. The 2070 runs much cooler due to a substantially lower amount of heat (115W vs. 190W) spread over a larger die area.

The 1080 is a "desktop version" mobile GPU.

 

but is the rtx 2070 a mobile or a desktop ?? for a clevo build? and the performace would be about same? not much of a upgrade???

how much does raytracing help , as well the temp change help alot?

i have p751tm-g system with a gtx 1080 would the rtx just slap in or do i need a different heath sink , as mine currently is a all in one heat spreader for gpu and cpu

 

Mobile. The desktop 2070 is 185W, the mobile 2070 is 115W. Unlike the Clevo 1080, which is 190W and matches performance of the desktop 1080, the mobile 2070 doesn't match desktop 2070. Like I said, the performance between the Clevo 1080 and 2070 is a wash. In some cases the 1080 is faster, in some cases the 2070 is faster. There's no point in sidegrading unless you care about ray tracing and/or DLSS. Temps on the 2070 will be significantly lower, after all you're talking 115W down from 190W, with a larger die (lower thermal density) to boot.

RTX uses a different heatsink, but afaik the GTX heatsink can be retrofitted to work with RTX card with some thermal pad changes.

 

Yeah. What he said.

Newer is often not better. This is especially true with version "updates" for Windows 10 and laptops. Unless your definition of better means newer. Newer is always... newer.

 

i can get a rtx 2070 for around 600 right now trying to decide weather to upgrade or not to the rtx 2070 from a gtx 1080, want to go 2080 but i dont have option at that cost , as those are 1300 to 1400 i believe

 

Absolutely not worth it, lol.

 

600 euro is to much for basically the same performance, imo maybe only because dsll when more and more games will use it and the implementation will be better. I am in the same boat as you but i decided to keep the 1080, its still rocking in Full HD and 1440 every game possible. The only upgrade that is worth is to go for the 2080 or the super one but that price...ouch. Will have to wait, ,maybe will get support for 30xx series then we can upgrade to that or the 2080 will become less expensive.

 

Newer is often better, especially for GPUs but don't jump in blind

 

Yes, quite often for GPUs. It depends on which GPU as well. It can be more hit and miss with laptop GPUs since they tend to neuter some generations more than others, and the degree of neutering can vary by OEM. Some seem to have less of an appetite for delivering a high-performance product than their competitors. In some cases, the product it is installed in can't support an equivalent level of performance in terms of thermal and power management.
