New to oc/underclock, 2 quick questions

post #1 of 3
Thread Starter 
Hey guys. Since it's starting to get warmer and warmer outside my PC started to heat more, i have no problems with it winter time but come summer i always had problems with it - cpu heating that is.

Running a FX 8350 with a MSI 970 Gaming here, and i just started testing out underclocking and all that. I started with 1.352V and got it down to 1.256 atm and there's a ~22-23Celsius drop in my temp, kinda alot. Now my questions are..

Should i undervolt the northbridge aswell? Is that necessary in an undervolting session?

And how can i test out the stability to make sure? I'm running Prime95 for like 30 mins now and no freeze/bsod yet. I got a bsod before when i was on 1.230 or something, thought i can get it down to 1.2 or even lower seeing as some people did but this is still decent., i guess..or i did something wrong to make it crash at 1.2? Thanks!

Like overclocking, with underclocking you still want stable lower volts across the board.

If it is getting hot at stock voltages perhaps you might consider more and/or better case fans. It sounds like it is just recirculating the same old hot air instead of getting cool fresh air.
