4.01GHz overclock: screenshot attached! - Page 2

post #11 of 17
If your still having trouble getting it to post between reboots try upping NB voltage .1v and bump the HT up .1v and then bump up the CPU-NB voltage .1 and that should help smooth out reboots.

I upped everything to get it stable at 4011mhz. It is running Prime95 as I type and I am getting a lot of throttle play from the mobo. Temps would reach 41 max on all four cores then drop the multiplier to 4 then to 16 again.

HT link @ 1.38volts
CPU Voltage @ 1.600 volts ( CPU-Z says 1.584 volts)
NB at 1.555 volts ( I think)
DRAM @ 1.650 volts


I know you guys said drop the north bridge volts, but I can't get it to post and restart/shutdown and post again if I set it lower.

Nice OC!
I'd recommend dropping the OC lower if you plan on it being a 24/7 overclock. Is the NB overclocked?
If your particular motherboard has a heatsink over the VRM's you can place a fan over it to keep the VRM's from throttling the multiplier.
Edit- I found that it does not,as the others said,you should reduce the voltage if you don't want to fry the VRM's.

Thanks guys. I figured out how to lower my NB voltage. I lowered it to 1.5 volts and set the NB frequency to 2000mhz, stock; 250 X 8=2000mhz.

Next up is to tighten my timing and set it to 1600mhz.

you can have the nb frequency higher, it helps stability, and for the throttling of the cpu, do you have asus cool and quiet on??? if so, turn the #$%^ off.

I have cool n quiet disabled. I liked the scores in cinebench, so I overclocked the northbridge to 2507mhz and set the NB: 1.40 volts and Chipset Voltage: 1.54 volts.

Thanks for the help y'all!
