3570K @ 4.2 with 1.088v at load?

post #1 of 5
Thread Starter 
How is this possible? I've had many CPU's but this just seems unlikely. I'm prime95 Stable overnight for 8 hours using small FFT's, temps in the 60's. It's a TURBO overclock too, 42 multiplier all 4 cores.

I've gamed for hours playing BF3 and Crysis 3, no BSOD or system errors at all.

Specs:

3570k @ 4.2 with 1.088 at load 1.1v in bios
MSI Z77A-GD65
EVO Push only (I have an extra fan for pull but is it worth it?)

This is normal for Ivy Bridge.  ;)

 

Adding the other fan can be worth it, especially for Ivy Bridge.  What core temps are you getting in Prime95 according to Real Temp right now?

That's a fairly good OC, but not unresonable. I've got 4.0Ghz on my 3770k with only 1.060v. You didn't win the greatest of the silicon lottery, but you now know about the awesome power of ivy bridge to be power efficient.

Good to hear...the thing is, I haven't even tried to lower it. Who knows how far I can drop volts. I just figured 1.1 in the bios was shot in the dark voltage, maybe achievable for 4.2. Now I realize that it's normal lol.

Thanks for your replies smile.gif

Its not until you try and hit targets like 4.8ghz and up where you see the crazy voltage increases.
