FSB hole with E6700 ES and lowered multiplier

[theraindog00]

I'm trying to push the front-side bus speed of various motherboards with an E6700 ES and have noticed that I'm not getting a post with much more than ~340-360MHz on a lot of boards. In the absence of exotic cooling, I'm having to lower the CPU multiplier to push the FSB, and am wondering if doing so might be contributing to the FSB holes I see mentioned here and there. I've tried a few shots in the dark at speeds above 400MHz to see if there is a hole, but none post.

Obviously, the E6700 isn't the CPU of choice for overclockers, but does anyone have any insight into whether lowering the CPU multiplier, or the fact that this chip is an ES, might interfere with higher FSB speeds?

:shrug: i can lower the multi on my E6700 ES chip and boot with the FSB at 500MHz+ no probs on the asus p5b dlx and the gigabyte ds3
