Have you tried any of the really low end gigabyte p45 boards too? I wonder if they can get anywhere close to 700 as well...

I think UD3L board may have a chance, as long as it has the key BIOS options we can tweak. Still, we need to find good NB more than good CPU. Will try at next stage.

I had once gigaboom GA EP45 UD3LR. I have done 624 mhz fsb on my old old e8200 c0 stepping, all air. I was very proud, but have no validation, only screen. It was back in 2009 or 2010, when I was starting my fascination on OC. It was before I found hwbot (polish overclock site with only screenshot to validate)

 

Wytiwx, thanks for sharing the knowledge!

 

Edit:

I have found this! LINK
it was 1.7 Volt, stock NB AIR cooling

Good job, man, and nice to see you.

E8500 + EP45-UD3, CPU-Z 6.70GHz done!

can do SuperPi 1M @ 6.40GHz but low efficiency

711 fsb 1M kinda tells me there is much more to come, given that you already showed off 710 fsb booting... Excited for what is coming next...

the 710 air boot cpu is a E8600, not this E8500.

Gigabyte P45 is not about efficiency

I think you need MCHbar editing for speed. But this is what makes them clock nice.

I remember this thread from back in the day at XS, might be helpful 

 

Congratulations @wytiwx awesome results!

tried mchbar edition but saw littile progress on mem bandwith or super pi

THX, man. I will try this method.

I've been playing with my board the last two days, and I can say that the MCHBar is loose on the -UD3 boards as well as the -Extreme(s). So it is definitely doable to squeeze some efficiency out of them. Probably 4-5s at least in 32M. Might give is a spin on 32M 4GHz LCC for funsies.

Edit: not sure high fsb 1T is possible though, I set 1T at 640MHz and OS froze.

Perhaps I edited the HEX value at the wrong mchbar address, I need to study that topic about strap tweaks.
