Wow very nice CPU!

Good score Digg. Did you test it on REX, what was your max 32m fsb with it?

[Eisbaer798]

Quad @Rex? I think that's not the best idea

Just to compare. I also think it's not a good idea to skip attempts to teach REX to OC quads:)

Thanks
Vcore is pretty low, but VTT is maxed out.. 1.70v. And that holding CPU back to run higher FSB i guess. I've got a better Score, but still 200ms to go for #1. Just 1MHz FSB more... AHH!  I will try barbonet xp.. maybe a bit faster than my simple XP.

@TerraRaptor
Because i want to know, i've tested a Q9550 on the P5E64 WS EVO.. 500 FSB 1:2 Strap 333 PL7. Passed 32m but freezes when i hit screenshot.exe. 
There are so much to test.. and i want to test it all. Maybe Rex can handle Quad better with only 1 Stick? Or with 2x1GB?

Think problem is cpu side. Highest I did with c2q and REX is 534mhz.

[Guest Digg_de]

I think 534 is good. What vnb for that?

I have compared the xp i used vs. barbonet xp.. at a total time of 12min36s babronet xp is 700ms faster.

Like mine standard 1.8v. Main problem for me was skews that time. I should retest it soon with all the new ideas I have.

highest i reach with a rex is 548mhz (Q6600) with a vNB @1,76 (watercooled)

What skews do you use?

And new ideas? Tell us! :-)

Make 3vsb mod feeding clockgen

Define optimum nbgtl

Several mchbar tweaks

There is one downside with the Rex i guess... no Xeon 771 Support.
