Hi guys, it's been a long time since we last met hasnt it? jk ;)

Well straight to the point. I've started oc my old 1090t cpu from amd and I've encountered some strange bugs. When I'm in the bios and set the cpu voltage to let’s say 1.49v with the core clocked at 4.(2-3)GHz the voltage increases to 1.55v when I'm running prime 95. I don’t know what causes this but I've turned off everything that can change the voltage automatically. Any idea why this happens? btw the mobo is an Asus Crosshair IV Formula.

And let’s say I want to set the voltage on the cpu close to 1.6v or more, would it be dangerous for the cpu?

No, 1.6v would be fine for that CPU, as long as you have decent cooling. Also, try AMD OverDrive software.

Depending, I've actually kicked that model up to 1.7 on client systems with no issues over heat generation. I DO NOT RECOMMEND running at a fixed 1.7v, though, as ANY cooling system can have issues, and we don't want a dust bunny to tale out the system. I tend to hit a safe maximum and work backwards to find the best combination for heavy overclocking. This was on a chilled watercooled rig.

Have fun, be safe! Sláinte!

are you using offset voltage and are you using LLC?

You dont know me but that's the way i like it!
