I have tried to overclock an e6300, however from the initial 266 fsb, i can only get the mobo stable up to 270.

Its not the memory, since i have tested it up to 355 mhz! (multiplier 3/4 and no errors in memtest).

What am i doing wrong? I believe this one is weaker than your version, but from 475fsb to only 270? Does it get THAT bad?

PS: Here's a fellow with same board as you, and also some problems: http://www.xtremesystems.org/forums/...hlight=945p-s3

Hope you or someone can help
The 945P-S3 is not the same as the 945PL-S3. The 945P-S3 does support a 1066 fsb. I was able to get a 945p-S3 up to 387Mhz stable......the 945P is very sensitive to PCi-E frequency. It seemed my FSB would not go beyond 3x the value of the PCI-E speed. That held true up to the point where Vmch / chipset cooling became an issue. I'm sure 400Mhz + on the fsb is possible with a Vmch mod......no settings for this in the bios.
