High voltages to get stable i5-3570k

post #1 of 8
Thread Starter 
Hello everyone,

I am having trouble overclocking my i5-3570k. I've been reading alot here, used this guide for my overclocking guide. (Great guide btw).

I can't get my 4.3ghz OC stable at lower manual voltages than 1.285.(Manual setting : 1.285v in bios. CPUZ shows: 1.296v -1.304v) This is really frustrating to me because i see people running 4.4 with 1.208v or something lower 1.22v With 1.285v 4.4Ghz wont even boot for me. So i assume there might be a problem somewhere?

System specs:

Asus P8z77-LX motherboard (Running latest bios version)
I5-3570k ( Scythe kotetsu cooler)
8gb viper 1600mhz cl9 ram (rated at 1.35v)
asus gtx 660
In win 80plus Gold 600w power supply

Naturally with these voltages im getting rather high temperatures - Up to 83C running prime95 blend at 1.285v @4.3Ghz. Looks pretty stable but that just doesn't seem right looking at other people voltages.



Any thoughts?

1.285V isnt that high for a 3570K

Maybe yours is a crap overclocker like mine.
I need 1.3V for 4,4ghz and 1.35V for 4,5ghz

It is his mobo the Asus P8z77-LX.
LX version is very poor when it comes to OC.
Mobo is gutted, all mosfetts heatsink gone and only 4+1 phase.

Board works ok for me up to 1.32V after that some wierdness happens.
Its running 4,4ghz at 1.3V now for over 6 months.

Dont forget 6 months isnt a long time for a PC to run at all.

I also have put heatsinks on the VRM's myself.... If they help i dont know, i like to think so but there is no VRM temperature monitoring on this board.
