Question 9x445 or 8x500

I wanted to get others to comment on overclocking a E8400. I have been runing 9x467 for months but am trying to see what my limit is and what is holding me back. My system will run above 500 mhz with a lower mult but not with the std 9x. I can get up to 525x8 with the same volts as 9x476. I do not want to raise my volts above 1.36 vcore. I think I should get more than 525 FSB if I can find my weak point. Anyone else try this? Oh this is the sys in my sig.

What do you mean better. Isn't a higher FSB better with the same speed? Well it might be very small. And it might be harder on the entire system at a higher FSB.

Using a higher multi is better as opposed to the higher FSB. By raising the FSB, not only does it increase the chances of hitting that wall but it also adds more stress to the Motherboard. Not to say it will not do it as you mentioned, but by increasing the multi to its max, you have a better chance to hit a higher Oc and being stable than you would at a higher FSB due to the stress and voltage requirements.

That's what is holding you back

took me 1.424v actual for 9 x 500 - 4500mhz (C0 stepping). 500mhz+ FSB will provide more overall performance, but make it more difficult to get stability, and probably require more voltage on the mobo, ram & cpu. I think to get over 4250mhz, you'll need more than 1.3625v actual, especially for an older C0. Lower temps will take less volts to get the same speeds, so lapping the IHS & HSF, or adding some more fans/fan speed may give you a little more out of the chip @ your 1.36v barrier. I take it your ram has no probs @ > 500mhz 2.1vdimm?

Jaredpace I have to agree. I will look at it this week a if I get time. Oh ya my dominators should be ok over 500 thats below their rating.

umm, holy shit.

you still have a lot of room dude. is 1.256 during load for 9 x 467? that's insane

I agree with jaredpace, 1.36v isn't enough for 4.5ghz. i'm surprised the CNPS8000 can cool this cpu so well at full load at over 4ghz speed. have you burnt with Linpack//LinX? I wonder what your temp is.
