Hello,

So my set up is

Gigabyte ga-p55-usb3

I7 870

16gb ram

Gtx 960

Evga 750w psu

240g ssd

H100i gtx cooler

So, i was trying to oc the cpu and couldnt get it to work no matter the settings. Only thing i was able to do was turn on turbo boost and jump up the multipler to 24, Which took the cpu up to 3.2 ghz. Im sure im missing something simple any help would be greatly appreciated.

I have my i7 940 running at 4.3 Ghz on an EVGA x58 SLI board. I will post specs when I get home tonight. Hope that helps.

My settings may not work on your board, but at least it is a try.

Cool thank you

stock its 22x133. if you lock the multi to 24 and then increase the base clock to around 150 you should be able to run it at 3.5-3.7ghz and keep the cpu core voltage under 1.4v :)

AMD Threadripper 5990WX@4.8Ghz

I have my i5-750 @ 3.8ghz, 1.385V. I think it's set up as 20x190 with RAM running just under 1600 MHz. It might help you a bit. I will try for 4 GHz one bright day though. But for now I'm a little worried to go to 1.4V or higher. Has anyone here some experience with high voltage on those?

I think it really depends on motherboard vrms. My motherboard had a really weak vrm that was known to blow if vcore went over 1.25v or so.
