Can't seem to OC further?

post #1 of 19
Thread Starter 
So right now I have my computer overclocked and my specs are shown below


Now my problem right now is I can't seem to overclock to anything higher and reach a stable OC, I'm not sure why but I have tried to up the bus speeds a little and up the voltage a bit but prime95 tells me my OC is unstable, any suggestions or if any more info is needed please let me know

What are your other voltage settings (QPI/VTT, in particular)?
post #3 of 19
You're going to need a lot more voltage - try putting it at 1.35v - that should be good to the 4ish range

is there anything that might be to do with my ram? my ram voltages are at the standard defaults, they are not oc'd at all, I wasn't sure if I shuld go past 1.3 volts on my cpu but I can try that to see if I can get stable OCs at 3.8 and higher. I just find it weird that its unstable at 3.7 ish

I think your bus speed should be around 191 for a 4.0 oc

turn your ram multi down to x8 will give it alot more stability and for a 4.2 it will be around 183 with a multi of 23 if you still cant post time to start putting those voltages up qpi/vtt should be around 1.3 (depends on how good ur chip is) and around 1.28-1.37v core should do the trick just depends on your chip again

Try this
V core = 1.6V
V qpi/vtt = 1.6V
V dimm = 1.85V

Then u r able to go to 4GHz+
