Well boys it's official. My "overheating" issues causing my laptop to shut down is being caused by bad thermal temp inputs from the cpu side. cpu is fine and cool. gpu is fine and cool. you can watch the temp readings spiking all over on all cores and then the shutdown countdown starts..
Computer shop guy said new motherboard after tearing it down and rebuilding it for two weeks...
Anybody know whats going down??
What options I might have??
This machine was custom built by hid evolution with stickers on the mobo dating March 2018


thanks my dudes

 

new mobos are currently $415

 

Has it been tested with another CPU?

 

ill give the gentleman a call with this question tomorrow..

 

Best of luck.

 

Might be time to change thermalpaste or reapply liquid metal. If you could, post images of the mount and the temp spikes.

 

Hi,

What is the size of the CMOS battery? (Its 2032 ?)

 

I managed to get the DMG apart this evening at work. Flashed the BIOS with a CH341a and put it back together with nothing left over which is unusual...

With many thanks to @thewizzard1 for his gentle encouragement, I now have the Dsanke BIOS on the DMG. Might go for the pin mod on the 9900K while I wait to find a 2070 for the TM1 and see if the heat sink copes.....

 

Yes, fairly certain its the 3v cr2032.

Make sure the VRM thermals are within reasonable temps and baby them up with good pads.

 

Yes, I can confirm that as well.

 

I actually ordered a 2070 today so I'll hold off until it arrives. I've lost use of the mill which is a bit annoying for the heatsink mod but I have Dremels and die grinders so should be ok. I've also got the 2nd fan to fit and wire in for the CPU. I'm excited to see what the RTX does for my gaming. I'm guessing with the vapour chamber on a single card, thermal throttling shouldn't be an issue with OC?

 

With the vapor chamber, the 115W mobile 2070 will be ice cold.

 

Big core, not much power, should stay frosty as you say.

 

As mentioned above, it should run really cool when paired with the dual gpu vapor chamber.
I posted this in the other thread, but for reference I'll also post it here; even a power modded GTX1080 runs <60c after hours of use at high frequencies (max fans and lm). And that sucker pulls north of 200w.

I believe you need to cut some of the soldered on copper parts, but the die coldplate itself doesn't need any work. There are pictures for reference of the mod on the forums somewhere.

 

@TheLuddite Good work, and congrats on the necromancy!

 

Yeah, I managed to find them around the forum for what needs doing. Seems fairly simple and I should be able to rustle up some copper plate to make up the thicker parts. Thanks guys. I'll post up as I progress. Thank you all for the help and nudges in the right direction!

 

Good luck, will look forward to seeing your mod.

 

Good luck and share pics

 

I managed to get everything in today, unfortunately I can't get it to boot past the windows installer sign. The CPU feels like it's getting very hot so I installed the third fan straight away. I haven't done anything fancy with it, just screwed it in a d wired it in, minus the 2 middle cables. It would still shut itself down before getting anywhere. So I moved it to my server room (I look after the IT, comms and electrics on a ship) and tried to give it some serious cooling, it still kept shutting down before windows could install. The laptop is used but its had a new motherboard and looks very little used. Especially compared to my DMG. I am guessing it's probably more to do with the USB drive having been through the wash today... I'll try a new one soon. Anyway, hope you enjoy my cooling solution..... Could this go for /r/ratemysetup?

 

I was being stupid.... took the boot drive from the DMG, took out a ram, the other SSD and fired straight up. Going to make a copy of windows to the new SSD and try and skip the USB....
All working fine now.

 

You in a data centre there?

 

No, a ships server room. 4 racks here and then 3 other racks dotted around the place with AV equipment around. Large AC vent where the laptop is feeding lovely cold air to the racks..

 

Ah so borrowing a bit for your own machine i see

 

Why can computers be so frustrating? Seems to just drop dead when running GPU and CPU under load. I'm mid ensuring all drivers are ok and then it goes into a BSOD, after waiting for 30 minutes for the driver download zip... danger of second hand machines I suppose!

 

Old faithful is chugging on quite happily while I run tests!

 

Well, I think I have some success and found the issue is probably to do with an overclock sitting on the BIOS from the previous owner which was running it too hard and overheating it. I've got it stress testing now on my server cooling duct

 

Because especially when you tweak them they are a system of many interlocking parts.

 

Very true, it's all good practice as well and is becoming just us much a hobby in the evenings as the gaming is.

Great news is, I have now found the problem. The actual problem is the EC fan control doesn't seem to be working. The 3rd fan seems to be dealing with idle temperatures on it's own until I remember to turn on the proper fan control.

I have used 3 different fan control systems now and I have gone back to Obsidians Fan control as I know it doesn't have issues with using the EC if I don't want to. I tried the new fan control that is on these forums and it's too much of a hassle with admin privileges etc to use at the moment. I'll re purchase Obsidians for now.

I have also just managed to upload Dsanke BIOS first time. So as the saying goes, practice does make perfect.

I'm disappointed with the 2070, I didn't think to look at simple things when I purchased it like how much ram it has and it's really not much more capable than my MSI 1070, which iirc, has 16GB ram and the 2070 has 8Gb. Not to worry, it's an in between card until I can get hold of a 2080.

 

I don't think there was.a 1070 16GB only 8GB for the desktop. Same for the 2070.

So you are not limited any more than the desktop cards.

 

Hey.
I upgraded my clunky beast C: with delidded/lm i9 9900k P0 and 64GB of b-die memory. Then I managed to get quite decent ram oc and here's results and some tryhards photos.

I don't know where I got that from, I probably misread it when I was looking at Nvidia inspector.

I am really starting to get annoyed with this TM, latest issue is whiteSOD just after windows settles down from a startup. Managed to get it in to safe mode and it was ok then so I'm guessing driver rather than hardware. I had it running nicely last night in MSFS with VR and then it just goes in to another problem. The DMG however has been rock solid since I bought it, second hand 4 years ago...

 

I have finally got the PC to settle down. I think all the issues where down to the fact that the chokes didn't have thick enough heat pad on them to touch the heatsink and take away the heat! Just done an hour long stress test on the GPU and it's much better.

 

If you want to squeeze a little more perf out of that P0, and you don't care too much about security, you can disable Spectre & Meltdown patches with inSpectre.

 

Already done that. For better performance or more oc headroom I should repaste CPU with liquid metal rather than nanogrease extreme, but now for me performance is more than enough .

 

Full liquid metal is the final step usually. It certainly helps those peak temps.

 

Every little bit helps, as a few degrees here and there end up being significant in the end.

 

Quick question while I'm away from my computer. My purchase was with Sager, so I have their BIOS. I need to adjust my AVX offset. Can someone give me a quick walkthrough on doing that? Thanks for your time!

 

If its not available in the bios you should be able to do this with Intel XTU.

 

In the Control Center, under memory overclocking, I can only adjust the voltage, not any timings. Will pushing this up in turn raise the frequency? The bar graph shows a cap of 2800 and I'm at the stock 2400. Seems a bit simplified.

 

No, pushing the voltage wont do anything else. Have a look in the BIOS.

 

Thought so. I did look in the BIOS but the XMP profiles are blank and can't be selected. Any thoughts?

 

Select them and they should set.

 

Turns out my ram sticks aren't capable of XMP.

However I have another question. While playing Valorant, I've noticed my CPU will sometimes reach 90°C, no matter what my graphics settings are, though only briefly. Undervolting my CPU through the Control Center doesn't seem to work, I don't notice any change in power draw or clocks. Using Processor Power Management settings works, but it's strange. If I change it to 99%, my CPU clocks drop from 4300 GHz to 3550 GHz. Changing it to 75% gives me around 2600 GHz. Does changing the power this way disable to boost clock and determines the performance off the base clock? That's the only thing that makes sense to me. Keeps my temps from going above 60°C though, so it's done what I wanted.

 

Peaks of 90 are not an issue. Are the fans ramped at this point?

 

Yeah I set them to max whenever I game. My headphones are isolating enough that it doesn't bother me one bit. But thanks for the reply! With Valorant I still get about 165 fps average with the lower clock, and my monitor has a 144 Hz refresh rate, so I might as well take the lower temps lol but it's good to know that short peaks are not a concern.

 

Yep, well within spec.

 

Peaks are often the culprit of BSOD.

 

Peaks within spec should not be causing BSOD.

 

Should not, but they do

 

I've not seen that with mine.
