OC: E4300 on D975XBX2

Hi everyone.

I'm new to OC'ing and have some difficulties reaching the OC I wish for my setup.

When I first got the board I upgraded the bios to 2692, but wasn't able to get past 265 FSB, no matter what setting I pulled.

After reading on this forum, I recently managed to get the FSB to 320 with BIOS 2618, but now I changed the CPU cooler to a Noctua NH-U12F my computer won't post.

Tried to upgrade the bios to 2692 again, but no luck.. And then back to 2618 - but that didn't make any difference now..

Specs:
Board: D975XBX2
Cpu: E4300 (multiplier 9)
Mem: 2x OCZ DDR2-6400 (4-5-4-15@800)

Bios setting that used to work:
CPU: FSB 320
RAM: REF 266 - MEM 667 (5-5-5-15)
No voltage or other changes

Bios setting that work now:
CPU: FSB 265
RAM: REF 266 - MEM 667 (5-5-5-15)

When I pull the FSB up to 266 -> NO POST

Anyone has any suggestions on how to sort this out?
Could it be my power supply not keeping up?
It's an new Antec I pulled from my Fusion case

Have you moved the bios jumper to post? If not try that, reboot to bios, choose default settings, disable watchdog, reboot, move jumper back boot again and see if you can boot up at default settings. If it works, go back in and increase your clock speeds gradually. Be sure you're not OC'ing the memory along with the FSB. Use this link to help sort out the memory speeds.

I'll try to disable the watchdog later today, thanks!!

That seems to have done wonders for my OC!
I'm back on FSB 320, and hopefully can reach even higher..

Thank you very much!

Glad it helped you jarlehal . Watchdog caused me similar problems. Can't really see a need to run it.
