    With the advanced timings I found the numbers on the left (I guess the auto numbers?) were lower so I went with them after testing your recommendations. Thanks

    BIOS is not F9 as well.

    Bear in mind thet lower timings are tighter timings and may cause issues. As your modules SPD doesn't contain values for these, the board is guessing them.

    I would recommend while striving for stability and while still over clocking to use the higher timings of 4-4-8-68-6 however if you want to test the timings you have set, that's fine. Any instability and I'd definitely try the higher timings.

    Will do, thanks for your help so far.
    From reading around I get my next question, do you think it is worth pushing for 7 or lower on the Static tRead Value?

    I'm running the RC for Windows 7 on this at the moment and have to say this board is really quick. I had an ASUS P5WDH before but it wouldn't read 8GB properly, changing to this plus your tips has meant I can now run my test VMs much more easily, thanks again!

    You may possibly be able to get tRead=7 going. However if it won't even boot with 7 set, it might require fiddling a lot with reference voltages, maybe even clock skews.

    I'm certain lower than 7 would be next to impossible, given I can't go below 6 with a stock 333 FSB.
