*** Official Clevo P75xDM and P77xDM/Sager NP9758-G and NP9778-G "Batman 2.0" Owner's Lounge ***

I7 6700k, P770DM (eurocom sky x6). I delidded without reseal. Just delidding by itself with liquid metal under the IhS only ( with original TIM above ihs and GPU die) reduces temps by 15-20 deg c. I 3d printed a delid tool. Im at 4.6ghz, 50mV adaptive overvolt, temps are around 72 deg at load. But my bios only lets me adjust the basics - multipliers, voltages and power levels - its a Eurocom Bios, not the Prema BIOS

 

Thanks for the feedback! I was thinking about delidding, but not sure how much that is going to change in the end. If I then could go up to maybe 4,5Ghz it might be worth it. Then again I couldn't undervolt anymore which would also increase temps, so I might not even get up to 4,5Ghz?

imo 80°C and below should be fine, right? My old Dell XPS 15 ran at 99°C constantly for 5 years without dying, so 80° is pretty cool for my standards ^^

 

If you need to decrease temps, delidding is totally worth it - but only if you have liquid metal on hand. Dont bother with ceramic tim cause it wont change much.

 

delid for 6600k means -15C for sure, even more. One thing for sure good temp=delid

 

Delid with a new taller IHS works even better.

 

Yes,but I have had very bad experiences with copper IHS... and by the end of the day you could win 2-3C... so I think it is not worth the fuss...

 

It's the nickel plated one from bitspower, it also lets you use liquid metal which helps too.

 

Guys, my thermal pads are pretty used, I would like to buy new ones... what size do I need for thickness? thx for your help in advance

 

If you want to apply LM I suggest using 1.5mm thermal pads instead of the stock 2mm pads over the ram chips. It gives better contact.
Something like this - https://www.amazon.ca/100x100x1-5mm-Thermally-Conductivity-Silicone-Mainboard/dp/B077HNHWYL/
1.5mm worked better for me (p770dm)

 

Oh my Gosh! It seems this thread is pretty dead!

Anyway, I hope somebody can help me out. I recently got my hands on a P771DM-G (XMG U706). It turned out that this rig has some "faults". I'm not sure how to interpret these symptoms, nor how to remove them.

It started by having "glitches" occasionally when I turn on the rig: the "Pattern" is always the same!


If this occurs, it won't boot to WinGoofs and the screen turns black after that. It's no freeze because the SSD shows acitivity. By powering off and on again it mostly boots normally and I can use it all the day long, playing heavy duty games ond so on.
At first I thought it's a faulty 980m, but it only occurs periodically when booting into WinGoofs like shown above. So I'm not sure, if the card is really faulty. I disassembled the rig and found out this:


It might be that this card has been exposed to some heat like a heat gun or something similiar because it's only there. Or maybe it's something like a shorting? I'm not sure.

After that I took a look into the BIOS (no Prema-Bios ) and found this

When I compare this with the Download-Site from XMG, I find this

It seems that the EC is pretty damn old and the BIOS is not the newest one.

So I am at a loss how to proceed from that point on. Should I first flash the EC and newest BIOS? Should I flash the 2nd EC too? Can anyone give me a hand please to determine what these glitches might be and how to get rid of them?

@Meaker@Sager @Papusan

 

Whatever is causing it, the GPU looks dead.

 

Intrestingly the glitches disappeared after installing Win 10 in UEFI mode.

Did several Time Spy runs to see how it performs under load. Have still to do more testing, but so far so good!

one more thing concerning delidding. does anyone have experience using a delidded cpu on a notebook?
was wondering whether to reseal it with silicone or just leave it "floating" with just LM between IHS and die. since the notebook gets moved around a lot more than a pc it might be unstable without anything sticking it together? but from what i heard the biggest gain through delidding is attributed more to the removal of the thick silicone layer and less due to low-quality TIM.

and one more thing: anyone have experience upgrading their CPU on the p751dm-g? i.e. how would the i7-7700k behave heat wise (or even 8700k).

Delidding is a must nowadays! I sealed mine 6700k with a very fluid superglue. Worked like a charm! But honestly: I think it isn't even necessary! The CPU clamp is fixing the IHS super tight. But it's up to personal preference.

I wonder using a 8700k in the DM-Series requires the Prema-BIOS and at least a hard-Mod, right?

I never bother re-sealing my chips as it can lift the lid again.

 

Ask @jaybee83 he runs an i7 7700k on his same laptop,for me i would advise you to go with i5 8600k or the i7 8700k(Budget choice) but of course you will need the help of @Prema & @Mr. Fox and for that dream of GTX 1070 on P751DM-G !!! i can go further by waiting for atempts to put the new gen RTX20xx in old laptops the issues gonna be the TDPs because some leaks talk about 180w !!! for the RTX 2060 with perf = gtx 1080 !!!! of course the desktop versions

 

Just to check before I do something foolish. Is it true that Clevo locked the MXM 3.0b slots by requiring all cards to have EC compatibility built into the card? I'd like to drop a P5000m into my Mythlogic P750DM-G (since it is about the only compatible card actually produced) but I caught wind of this potential issue just before I was about to execute. If this is true wouldn't that make the MXM slots virtually worthless in these systems?

 

Every machine requires it can read sensor data from the MXM slot as it has to know what to do with the fans.

 

Ok. That makes sense. But considering Clevo doesn't update drivers - they certainly don't let us know what's compatible in GPUs. I've only heard of the MSI 1070 being EC compatible - but there is the IHS issue. The P5000m would work from a IHS standpoint but no idea about the EC.
It frankly appears that these laptops are almost as worthless as the BGA garbage that is out there (not quite, but close).

IHS? The nvidia GPUs don't have a heat spreader.

 

I dit it! Delidded my 6600k. Used just a pinch of silicone under the IHS because I was worried it might slip off the die when moving the whole thing from Dr Delid back into the notebook. Pretty sure I used to much LM, but at least covered the 4 gold thingies on the die with silicone so I hope it'll live.

Went @4GHZ small FFTs prime95 from 93°C to 70°C, ambient 21°. Though it probably helped that I removed a lot of dust while taking it all apart

Now off to see how far it will go. Everything below 80° at 100% is cool in my book.

 

Delid does make a MONSTER difference!
Enjoy

 

Probably half and half on the temp difference, nice work.

 

@Meaker@Sager. There's a CPU HS attached to a GPU HS and it's inside the computer. If that is not an Internal Heat Sink by all means please let me know.

That's just a heatsink, IHS stands for Integrated Heat Spreader, that's the metal CAP on the CPU>

 

Hi Guys,

I have issues starting up (stuck in bios loading) my P771DM-G.
Since I never updated my bios in the last years I was wondering if you can help me finding a correct bios for this configuration, as can't find a official one on the Clevo site.

Thanks in advance.

 

Normally your reseller would provide it, but without booting something you wont be able to flash it.

 

My P770DM has the Prema Bios, OC to 4.6 but still don't see the overclock fan option in CCC... how does it get activated?

 

Did someone tried GTX780m in the P751DM model? Is there a chance for this GPU to work in this machine?

 

I don't think anyone tried a step back, something like a 970m would do much better.

 

For now I have only 780m, just wondering if the machine is able to boot with it. If so then it is fine for me, and the card is MSI one, so I think first thing to do is to flash a clevo vbios.

 

Ive run a 780m in both a p87 & p75 for troubleshooting purposes. Units posted and booted into Windows fine. You will most likely need to look at thermal pad placement.

Edit: vbios was from svet/johnksss

 

It wont damage it to try.

 

That sounds great, thanks for the great news! I will give a shot with Clevo vbios first.

 

Just make sure vrms make good contact if you intend to 3d load the cards.

 

Has someone tried G3900, G4400 processors in P751DM model? Are these CPUs supported by default? Or the only ones supported are core i series?

 

They will work but g-sync can be unhappy.

 

gsync is overrated... eventhough I have it, I have never even switched on...

 

It can depend on the person and games being played.

 

So I have installed a Skylake CPU in the P751DM, and I found that it does not boot without a vga card just like P751DM2 does.
I have installed the MSI 780m card, it turns on and responds to NUM/CAPS lock, no image and after a while fans go max and beeps.

Can anyone please help me with a proper vBIOS for the 780m to work in this machine? I will program it with the CH314a programmer.

 

Have you looked at the techpowerup database?

 

Yes. Flashed latest vBIOS from Clevo with the external programmer. It boots with image, but still fans go max/beeps and shuts down. In BIOS, VGA card is listed as unknown. Maybe custom vBIOS is the only solution? as @ tranquil911 said that he had vBIOS from svet/johnksss.

 

It may have to be, I don't think another standard file will work.

 

The vbios I used was from tech inferno. Filename is/was Nvidia GTX 780m - 'OC edition' - rev02.zip

For what its worth the 780m was a dell card with the above vbios flashed with nvflash.

with @Johnksss blessings I can send you a copy

 

Thanks a lot! Waiting for @Johnksss response!

I have discovered a strange behavior of my p751DM, reinserted several times the 780m (with flashed clevo vbios from TechInferno, tried also with dell but has some other issues) and it worked fine for an hour or so (thought it was the vBIOS, because it worked fine after some reflash via nvflash), downloaded driver to mod and install and even did not run the installer and then it began again that thing with fan max with beeps, after 20-30 seconds it went back to normal for several minutes but after that the issue persisted again and now persists permanently.
Could this be a motherboard issue (VGA thermal maybe), or which are the causes when the laptop will behave with fans max/shut down after a while?

Any opinion is much appreciated

 

Sure. Go ahead. Thanks for asking. I hope it helps.

 

@Johnksss, thank you a lot for the help and approval!
Waiting for @tranquil911

 

Check the fan is behaving properly.

 

When CPU heats a bit, CPU fan spins. GPU fan sometimes might go max while CPU fan does not spin, but if the GPU gets warm GPU fan does not spin. That is why I think it could be a thermal sensor/circuitry issue.

Using Fn+1 max fans, changes nothing, it will have the same behavior.

 

It could be the gpu fan having issues.
