Stress testing then undervolting

michty_me · 24 Jul 2019 at 10:11

Hopefully this is posted in the right section.
I've just purchased a new laptop and interested to see what the temperatures it may hit under a fair bit of stress. This is mainly due to reports of poor pasting. What programs are recommended for doing this on a laptop?

I am also looking at undervolting it to help drop the temperatures a bit along with re-pasting with a decent paste like thermal grizzly. Are there any guides or tips on what software to use and how to do the undervolt?

All advice welcome!!

Prime95 using the small FFTs test is what I use (max power/cpu/heat) to do a max load test.

Ok thanks. I'll get that downloaded and see where I stand in terms of temps.
Any ideas on undervolting?

No experience in that area unfortunately.

Ok thanks anyway. I'll give prime a go!

I've done some digging and the undervolting looks quite simple using throttlestop or Xtu.
I've also read MSI afterburner can help set things for the GPU but not really looked at that much yet.

Usually at stock they are well above what they need to be in terms of voltage. If you plan to keep it at stock then just undervolt until you get instability with p95. Although you don't really need AVX when testing, if you use prime ensure to download ver 26.6 as this doesn't have avx included.

You can look in the bios or CPU-Z to see what the voltage actually is and just reduce a bit at a time. If its at say 1.2v then just drop it straight down to 1.1v and test and tune in with around .02v at a time.

On todays cpu's stock settings (inc turbo) run at around 1v.

Ok great. Thanks for the info. So essentially changing it in the bios is what throttlestop/Xtu would be doing in Windows and would require redoing after a reboot etc? It's an i7-7700HQ with a 1070 graphics card if that makes any difference.
