Are you overclocking with the fsb, aka, CPU frequency - or with the multiplier? Does this CPU have an unlocked multiplier? Have you given the CPU any additional voltage?

 

[byrocro]

my multiplier is unlockt, oc with cpu host/htt clock and cpu host/htt boost up clock, cooln'n'quiet is off, didnt rase voltage since i dont know how but everything i need to oc is ulocked cpu,sb,memory, everything if need for some pictures of my bios just say

It will be much simpler to overclock with the multiplier rather than the CPU host frequency but to get very far you must increase the CPU core voltage. Monitor core temps with HWMonitor and stress test with Prime95 blend. Don't let your core temps exceed approximately 55 C.

ok but my max multiplier is 13.5 and i cant go higher then that and when i want to increase voltage i get numbers like 0.0457 does that add to my 1.36v or what that i didnt get how it works

 

[trents]

Then its locked. When we ask that question is it locked or unlocked we mean "can you make the multiplier go bigger". All CPUs are unlocked in the other direction.

oooo i get it now so i cant oc my cpu r there is another way to oc???

You got a link to the motherboard website where the manual for that motherboard can be looked at? Need it really. To see what they are calling FSB which when raised will raise cpu speed.

@RGone cant find any user manual but here is the link of my mbo
