I'm new to conroe overclocking.
I just got my new setup with 2GB of mushkin enhanced DDR667 3-3-3-10 ram and an E6300.
I have it set to 325MHz FSB with the memory at 1:1
1.35v vcore
1.75v PCI-E voltage - is this the northbridge voltage?

I tried 333FSB with no success. 325MHz seem to run prime95 overnight with no hitches though. So it seems like there is some kind of FSB wall. The PCI-E voltage does not seem to really affect the FSB overclocking. I'm not sure if that's the northbridge voltage. How can I push this higher?

what version of the bios are you running?im using 7.15 beta right now ( 7.21 is out ) and Im using 375 stable with my NB at 1.7v ( yes the pcie voltage is the northbridge ) What im not sure what timeings ur using for the ram try loosing that and boosting the ram voltage some more. Im using 2.3v on my ocz plat 800mhz. also I noticed on my board the voltage set for the cpu seems to be .o5 off so if its set to 1.45 on the cpu Im only getting 1.4. theres a 34 page thread on xtremesystems with this board might want to read through that.

I was using 7.0
I just tried 7.1, and I was able to hit 350MHz FSB. I haven't tried higher yet.
Seems like 7.0 bios was holding me back.

ok I hit a wall at 365 with the NB at 1.75v.
should I get the 7.21?
Live update only took me to 7.1

I just tried the 7.21 bios.
It still won't overclock for shiet. It OC's to 325FSB with the stock 7.0 bios. After I switched to 7.1 and 7.21, it will reach 360FSB.. but it won't pass prime when overclocked. PERIOD. Even 300FSB won't pass prime.
WTF IS WRONG?!?!?!

many owners of this mobo are reporting diff experiences with this board using the various version of the f/w that have been released. why not try and post over the xtremesystem thread above to see if someone there could help you out?
