Overclocking noob - sense check needed

breathe3asy · 10 May 2014 at 18:48

I've had my 920 since 2009 & never really done it justice in the OC world. Well I finally woke up & bought a decent cooler yesterday, & after 5 years of use, this chip is doing me proud with a decent OC to 4.0Ghz.

BCLK 190
Multiplier 21
Turbo Mode Off
Speedstep On
HT On
CPU 1.35v
QPI 1.35v

I'm hitting 70-75 degrees in Crysis 3, will this be okay or am I running too hot? I'm using applications I use as a benchmark rather than stress testing programs just because that makes sense to me. & Crysis seems a demanding game to run

Appreciate any hints/tips on this.

Edit: Idle temps 35-40 degrees

Does that CPU and QPI really need 1.35v to stay stable ?

If so then you are at your limits and I wouldnt push anymore through it,

CPU + QPI are the only values that seem to make a difference with stability, but yes I can't go any lower on the CPU without BSOD in Crysis at some point. I may be able to get away with lower on the QPI but not by much, + QPI does not seem to affect temps a great deal.

4.0GHz through 190 x 21 (Turbo off) seems more stable than 3.8GHz 190 x 20/Auto (Turbo On) which is confusing.

Makes sense to me, mine preferred the odd multipliers to the even ones.
