    Basically; I set in BIOS 5-4-4-8; and tRFC to 35 cause I guess the DFI doesn't like this one to be tightened too much.

    What about yours?

    Great Results and great mobo and CPU youv'e got there .
    Can you Post SPI 1M ??
    Ok; I'll do one; but I rather prefer to test with 32M. It's much more interesting to assess high clocks stability.

    Thanks DDR3 version will be called T3R.

    Here's an improved 32M. Definitely this board is clocking both CPU and DRAM like a charm.

    great going bro... i've received this board yesterday, will try it with my E8500 and my cascade too
    5.5ghz stabilty test is nice... but times is not that good ... is it the board or you not tweak the pi run??

    I'm afraid the E8500 won't be pushed too high with this board. FSB limit is somewhere within 530 to 550FSB here.

    I haven't tweaked the Spi32M, but I guess times aren't too bad considering the FSB.

    Slight improvement. 9m49s might be expectable.

    Well done man Great board, look at that DDR2 going wild ... Excellent ram clocker as always

    I suppose you mean though 8m49s and not 9m49s ...

    Nice impressions...

    BUT everytime I watch one of your results I have to adore Lady Bertha!

    Dunno... Well maybe, but with 2v+ and -115C / -118C.

    So, I've removed the CPEV from 2nd stage of Petite Bertha Cascade, and try to get a good amount of R1150 in order to achieve some decent temperatures. First tries weren't very good cause without CPEV I've lost about 10C+, pressure for pressure, load for load.

    But today morning, before changing the captube lenght, I've decided to go for a bit less of R1150... and I finally got pretty nice loaded temperatures... at about 5.6GHz using 1.97vCORE for Spi 32M, top/'hotter' part of the evaporator shown -103.5C (evap pressure was 0.6bar that means -112C).

    Well, that's nearly the same than it was with the CPEV installed, that's damn good considering the load.

    Ok now, back on topic. I've ran a Spi 1M as requested earlier in this thread, and then improved the 32M. I definitely love this board, very reliable voltages, and clocks DRAM like a charm.
