Question I need help with my i7 overclocking

[Rodian_1]

Hi,

I'm trying to overclock my i7 3770k. My bios shows 4.6 ghz but when I go into windows and try to stress test cpuz only shows at 4.4 ghz, I have no clue what I'm doing wrong (photos of screen below). I did some research and checked the windows power options and made sure it was in balanced mode. I have only overclocked once before, my i5 3570k and looking back, the same thing happened there. Stuck on 4.4 in cpuz but not in bios.

I'm dubious about updating my bios because I've heard horror stories of it bricking the mobo. I daily upload to YouTube so cant have a PC that doesn't work.

Any help would be very much appreciated as I don't really know what I'm doing even after reading a bunch of articles about OC'ing I cant find an answer to my problem.

P.s. I know my system is old but I cant justify any upgrades at the moment. Just made a small upgrade from i5 3570k to i7 3770k (in case that makes any difference).

Thanks.

So what's wrong with 4.4Ghz instead of 4.6? It's hardly going to make any difference - maybe 1%

Whay version of prime 95 are you using? It could be an issue with avx offset.

I suggest not overclocking untill you fully understand what each setting change does and what parameters you have to stay within for the safety of your system.

Absolutely nothing wrong with 4.4 Ghz, very happy with that. I was just wondering why 4.5 or 4.6 wasn't working? If there was something wrong I don't want my cpu blowing up or anything like that.

it shouldn't blow up or melt - it has built in safety.

From what i can see its V 29.3, Build 1. I think ill leave it at 4.4 until I have read up more about how it works because i have no clue what an AVX offset is.

Try getting p95 version 26.6. More recent versions use avx instructions which tend to heat the cpu a lot. Because of this, the cpu slows a few hundred mhz to prevent the cpu from getting to throttling temperatures.

Try getting p95 version 26.7 i think. More recent versions use avx instructions which tend to heat the cpu a lot. Because of this, the cpu slows down.

26.6 is the one normally suggested. After that version, like you said it uses avx.

Thanks, I'll update prime and see if that helps.
