2500k wont boot past 4.5 help - Page 4

post #31 of 37
4.5 is a really good overclock...........
don't push your rig further..............4.6 vs 4.5 is just a 2.2% performance difference
---------------
that divide disappears too when you have a much slower(than the CPU) RAM, QPI etc. etc.
Just stay content with 4.5GHz and don't burn your rig for <1% performance gain....

That's just silly. He has great watercooling, I'm 99% sure temperatures and voltages aren't a problem. With a good chip/mobo he could do 5k, and that's quite the increase over 4,5 or whatever.

I Have a pretty good looking 4.8 overclock going just not stable yet getting the .5 rounding error in prime95. I'm also not sure about what kinda vcore I want to run 24/7. I'm also still on the fence about sending it back to newegg and getting a sabertooth or something.

The usb problem is if I boot in at these high clocks the first couple times my usb wont work right then in fixes it self but when I go back to stock I have the problem for a bit its really weird.

I would take those settings you used Hambone07si Or I will look for them in the post. I just don't know what vcore and all I really want to push for these higher clocks may not be worth it.

Rounding errors means you're almost stable. Try lowering your memory settings (or increase memory voltage) and run Prime95 again.

I'm running mine @ 1.6v (1.5v stock) 1600 ( 1333 stock).

So for an answer to your question, yes. Might need 1.6v but still test it.

_s3v3n_ it seems to be better now I am running prime95 at 4.8 right now with my ram volts at 1.545 and its doing better. My vcore in cpuz is 1.4 as that the max I feel safe pushing I want this chip to last. Hambone07si I tried your setting for 5.0 I can get in with more volts then you but I don't really want to push past 1.4 volts anything I can get under that will be as much as I go.
