Still can be done, the cooling is the same imo.

 

With our Grizzly Conductonaut + Fujipoly Extreme Thermal Pads upgrade, -100mV undervolt, Intel® Core™ i7-8700K OC'd to 4.8GHz on all 6 Cores with the Custom Prema BIOS, w/ nVIDIA GeForce GTX 1080:

EVOC High Performance Systems P750TM1
After AIDA64 stress test, several benchmarks and 2 hours of intense gaming at Ultimate settings...these are the highest temperature spikes we recorded:
GPU = 64C after benchmarks and AIDA64 Stress Test - 84C after 2 hours of intense gaming
CPU = 88C

 

You should be able to undevolt a great deal more than -100 on 3.7 GHz. Try about -150 and go -5 steps from there till you blue screen. Should tame those temps

 

I've been using Prema BIOS already.

As @Donald@HIDevolution stated, the temperatures they tested are well within what I was experiencing.

As others have also noted, the laptop is smaller which results in higher temperatures.

I guess, to reiterate, my main contention was finding a way of playing on high/ultra whilst being at a max temperature of about 80ºC.

Yes, I can OC the CPU up to 4.8 GHz safely, but I choose to use 3.7 GHz at the moment because I didn't know that there wasn't any other way to lower the temperatures while gaming on my desired settings.

That being said, I thank everyone here for your inputs.

 

All 8700K can run +4.8GHz. Is this a binned chips? The reaction come due you running it base clocks (3.7GHz). And You use ThrottleStop on top of Prema firmware. Easy to put up higher clocks with TS and test out how temperatures will be (I get that you search for lowest possible temp - but increase clocks a notch and still have decent temp shouldn’t push much higher Cpu temp). It’s about test and trial.

 

I am very exicited as I would like to use my TM1 @ 4,7Ghz + 1080 gtx... I am curious if it can make it on acceptable temps...

 

Same clocks and (voltage) ain’t the same as you get 100% equal temp for all chips even delidded. And you have variance in heatsink fits and the thermal paste application (even Liquid metal). It’s trial and error Post results when you get them.

 

I will definately, however I need to fix the 1080 vbios problem from dm3... If I am lucky, then I can start testing

If it works well and acceptable temp I think I will sell my F5 even though I love it... TM1 heavy as a rock comparing to it, however I do not need two 15' laptop...

 

If you end up with two it's best to have two different sizes, I have a 13.3" 1.2KG to pair with my 17.3" 5kg beast

 

Yes, 751tm1 and 775dm3. However my favorite is the MSI16L1X but I will keep the coffee lake one...

 

I'm running on base clocks because it's my default "Battery" setting in TS that I use for browsing. It's what I use to play games that aren't resource-intensive, but I use the profile that runs at 4.8 GHz while playing more demanding games. This goes back to my initial post on having extreme temperatures, albeit within testing range, while playing games like PUBG, Fortnite, Assassin's Creed: Origins, etc. where the fans just blast on full all the time.

 

What's your definition of extreme temperatures?

 

I thought that getting to 88~90ºC temperatures was extreme enough when playing for about 15 minutes in PUBG/Fortnite/etc. type of games.

It's clearly within the max temperatures tested by HIDevolution, but it does dampen one's resolve to play games when all you can hear is the fans blasting at full speed and your room gets a lot warmer because of the laptop's heat.

 

TBH that's not too shabby for an 8700K at 4.8. Quite a bit of heat and fan noise is to be expected when you pack such power inside a 15" chassis. Put on some headphones.

 

Any news mate?

 

That and an equivalent desktop would get warmer.

 

Hello again,

I'm having some issues trying to get Gsync to work. I have the Prema Bios, 1080, and 120hz panel installed on my P751TM-G. HID helpdesk said my laptop should support Gsync, but there's no option in the Nvidia control panel. I've tried reinstalling graphics driver, I've looked through the Prema bios but can't find any setting that would help, the Clevo Control Center doesn't have anything related to MSHybrid mode. I've reinstalled CCC and even went to the release version. Would anyone have any suggestions? One thing I did change, the laptop originally came with the 4K screen, but I had it swapped out for the 120Hz panel. Not sure if that affects anything in regards to bios options.

Thanks for the help!

 

@ Justin Tullos what is your CPU? Not all panels are compatible with GSync. What is your panel?

 

The panel is: B156HTN05.2, and my CPU is the i7 8700K.

 

@ Justin Tullos i think @Meaker@Sager can give an answer. But this panel and the processor is suitable, and with it the gsync should work

 

Your order shows you have the 4k screen, which does not support G-Sync. Did you change the screen?

 

If it came with a non 4k screen did he actually get a -G GPU?

 

Hey Donald. Yeah changed the screen out. Working with the fantastic help desk over there, Zoltan is great!

 

Unfortunately, when you got the 4K non-G-Sync screen, you also got a non-G-Sync GPU. The only way to get G-Sync now is with a new GPU that supports G-Sync.

Zoltan is working with Prema to see if he can help...but that is a long shot.

 

Nvidia put a LOT of protection mechanisms in.

 

Playing around with measuring temps/etc. during gameplay today on the Sager 9155. The screenshot is of selected sensors from HWInfo's sensors window during a little under 1 hour of GTA Online, with aggressive-style full-map gameplay (i.e. very active, intense driving - this was not a mild walkabout in the city). I have the following setup:

Hardware: 8086K CPU (basically a factory-overclocked 8700K), 1080 GTX GPU, 32Gb 3000-Mhz memory with "meh" timings, 1TB Samsung 970 Pro NVMe SSD, G-Sync-capable 144hz LCD panel

Software:

• Windows 10 Pro
• NVidia driver from Windows Update (23.21.13.8927 dated 4/17/2018) - *not* Nvidia's latest version, nor from Sager's driver downloads website) - no other NVidia driver has previously been installed on this Windows 10 build.
• Force-installed unsigned Dolby Digital Advanced Audio sound driver for the Realtec chipset, using Dolby "Gaming" sound preset
• NVidia Inspector using GTA V profile defaults, but with framerate limited to 74.6 fps to keep GPU temps under control
• Grand Theft Auto V from Steam, using "Very High" graphics settings @ 1920x1080, except for "High" settings for Grass, Borderless Window with Vsync disabled
• NVidia driver set to use G-Sync for fullscreen and windowed apps
• Windows 10's "Balanced" power plan with performance slider at maximum performance setting
• Sager/Clevo control panel's default "Entertainment" mode
• All CPU/Memory/GPU settings at default clocks, frequencies and voltages - no undervolt for this session

After almost 1 hour of gameplay including fast driving and flying over most of the GTA V map, with fans set to "Auto" (they were audible but not at all distracting, especially with the speaker volumes possible using the Dolby Advanced Audio preset - system volume of 70 is loud enough to be heard by the neighbors if my back door is left open), here are a set of selected temps/frequencies/etc. from HWInfo's sensor window:

 

Very nice

 

Guys,
Thanks for your help, just to report back after hard flash of vbios from TM1 model to the 1080GTX taken out from DM3 works like charm! The 1070 taken out from TM1 works perfectly with the original vbios in 775dm3, so the backward compatibility is OK!

Thx for your kind help and support especially Meaker, Papusan and yrekabakery for the vBIOS!

It is time to test the 8700k+1080

 

Whoa. Does this work with our system?

https://www.ebay.com/itm/new-for-Cl...750dm-HEATSINK-Upgraded-version-/173273237163

 

It should fit if you look at them side by side. Pad layout is the same

Very Interesting! This one has the potential to remove the conjoining heatpipe and snipping off the 2 connecting metal forms. Very nice to have non-unified cooling for many applications.

The old one has too much interconnection that is attached directly to grills to modify

New:



Old:

 

I'm gonna order one and see how it goes. If the upgraded version improves GPU cooling without impacting CPU thermals too much, it'll be a huge win because lord knows the GTX 1080 needs help in this system.

 

Hi all,
I was testing the machine a little, and dont get why the hack the 751tm1 gives so much voltage to the cpu... I have set to 4,5Ghz all cores, in intel xtu made -130mV offset, and even with this it gives 1,31-1,32V to the cores... If I go down with the offset it freezes (eg -150mv).... As I have read with 4,7Ghz almost all cpus can handle not more than 1,3V... the bios is pretty emtpy, I cannot set anything... thx in advance

 

Try ThrottleStop. As well statick voltage. Is this load voltage aka in full bench load?

 

Yes! Even If I set static in throttlestop it is going up and down... I have tried 4,7Ghz @1,3V, in hwinfo it is still 1,451,48V for 4,7Ghz!

 

Run Cinebench R15 + Hwinfo in the background. Take a few screenshoot in the 3/4 end of the benchmark (With info of the clocks, volt + Cpu Package Power). Reset min/max values on Hwinfo monitoring after the bench has started to run 100%.

 

lite browing...

cinebench...

do not get it...

 

browsing, almost zero load

full load under cinebench

result:


any idea what is going on?

 

IA AC DC loadline=1 ?

You know the drill by now.....

That screenshot is speaking "IA AC DC=2.10 mOhms (Auto, equals 210, 210=2.1 mOhms)"==voltage spike by 2.10 mOhms of resistance at full load.

Set it to 1 in Bios (= 0.01 mOhms) and this problem will stop.

 

Hi,
I know the drill, and i was looking for this in the bios, the only problem it is not there... the oc option of the bios is very limited these settings are not available...

I have stylenote notebook with their bios as i see.... does the stock bios has this option? Thx

 

Delete ThrottleStop ini file in TS folder, reboot and try once again. Put Default adaptive voltage and fiddle with undervolt. Put equal for Core and Cashe. Test and trial.

Post pictures of all bios settings (advanced).

 

Maybe this is what killed my CPU.

 

The core needs quite a voltage spike to do damage, other parts like the IMC are little more sensitive.

 

I did not push the cpu too much due to the voltage, however it never reached 90C, so Its likely to killed it, but of course who knows... I will check TS again and give feedback, thx for the help to everyone... clevo without proper bios is not fun....



Sorry that they are upside down no luck with throttlestop, no matter what I set, it does not change anything... I have tried override in bios (0, 0), black screen no boot, I needed to take out the bios battery So far I have no idea what I can set...

what is the current stock bios for 751tm1? I can change the bios, maybe it helps...

 

No CPU would boot at 0V.

For 4.6 try override 1200mV and move down/up in 25 mV increments from there.

Fn+D while pressing power button may also work for BIOS/NVRAM reset if your reseller didn't block it, easier than removing the CMOS battery.

I had the same stock BIOS 1.05.10, with an older EC than yours, 1.05.02 instead of 1.05.03.

 

Override 1200mV seems too much. Maybe try 1150 or defauld adaptive with -150mv offset (46). Then tweak voltage with TS. Use one of the 4 TS profiles for default Bios settings for startup while he test. He can put his tweaked settings after finished tweaking.

 

-150mV adaptive might be fine for stock clocks, not sure about OC. Not everyone has Silicon Lottery binned CPU like yourself.

 

Default volt is good for up to 50x on many chips. As long he can boot into windows with suggested settings all is good. The rest can be done with TS

 

I could only do 4.6 on default voltage, guess my CPU sucks.

 

Thx, I will try will 1200, and we will see... for daily use, it is not a problem that is gives constant 1,2V? even if the cpu is idling?

This one does not work, even if I give -150mV the voltage spikes like 0,2V! I will try and give feedback... prema bios is deperately needed....

fn+D did not work interesting but did not however you help how to remove the keyboard...

btw, you BIOS has this 'IA AC DC loadline' option?

 

IA AC/DC Loadline is not in the stock BIOS. I tested both set to 1 and while it kept the VID constant, it caused more instability and throttling under load than when left at default. I would not worry about the idle VID spikes.
