    Right, I flashed down to F7 and then up to F12. Heres the results

    F7:
    Normal - 1.888v
    [0.1v] - 1.744
    [0.2v] - 1.888
    [0.3v] - 1.888 (not typo)
    [0.4v] - 2.016
    [0.5v] - 2.032

    F12:
    Normal - 1.968v
    [0.1v] - 1.824
    [0.2v] - 1.888
    [0.3v] - 1.968
    [0.4v] - 2.032
    [0.5v] - 2.112

    Using [+0.5v] at the moment, Prime95 is failing within a minute. CPUID HM is reporting 2.13/2.08/2.14. SpeedFan 4.38 is reporting 2.13, and EZTune 6 is reporting 2.3v (this is read from the tuner tab, hitting advanced to open up the voltage tab and then its the value on the right) - No idea whats going on with EZTune 6.

    Regarding stability, I'm guessing I need to up the MCH setting. Any suggestions for that please?

    would be to increase MCH (northbridge voltage step by step to see if stability is reached.

    ok If your at 1.1 your target should be around 1.34 but lower with stability would be better
    OH and I also did not find easytune to be reliable.

    I'm not sure what this means, but I'm guessing you are refering to the MCH voltage. Can't find anything in the BIOS, nor CPUID HM that gives me a reading close to this except for the CPU vcore.

    With the DDR2/DDR3 voltage, I crashed 2 or 3 times when I tried to run Prime95 which used [+0.5v] on the DDR2/DDR3 setting and [+0.3v] on the MCH setting - which was as high as it would go. Decided to leave it for the night as I didn't have any more options.

    I returned to the computer to find that the previous [+0.5v] setting is now giving me only 1.96x volts instead of the 2.1ish volts it did 8 hrs ago. Rebooted a few times, going to FailSafe then Optimized modes. On the DDR2/DDR3 setting @ Normal, I also got 1.9ishv, @ [+0.1v] it was 1.7 v, @ [+0.5v] it was 1.9 and only the [+0.6v] setting gave me 2.1v

    I'm pretty sure after a crash, the DDR2/DDR3 voltage somehow changes, but I'd need more crashes to confirm. Does this point to a dodgy motherboard?

    Yes I don't believe a power supply would cause this, but you may want to try another power supply first.
    It looks like an RMA if I ever saw one with the bios misreading like that. They should repair it. That board or bios is bad. The way it increases in voltage means it is faulty. You may want to copy and print up the voltage details you performed. Send it to them so they will have something to work with. Communication is the free way to information. I am sorry for this inconvenience. Please let us know how that comes out.

    So, how exactly do I get hold of gigabyte tech support?
    I tried the link GIGABYTE - Support&Download - Technical Service Zone and filled out the forms etc etc. This was about 3 days ago now and the only status I have is:
    [X] the mail will be processed

    I know its not even been read, as there is a status icon to confirm that also.

    Any ideas how else I can contact them?

    Any ideas how else I can contact them?
    If you don't receive an answer soon from the place you contacted, or the contact details that artdrivers posted, I'd give Lsdmeasap a PM. He's extremely good at kicking tech support up the bum (getting them moving). I'm sure he'd be happy to help, bear in mind he's a busy chap, so you may have to wait a little for a response, depending on circumstances.

    They are all super busy right now with getting ready fro P55 release. Did they ever answer you at the tech support site yet? Normally that only take a few days 2-3, you should have for sure received a reply by now

    My contact for such things is out of the office until the 31st so I can't help too much until after that. They really dont offer help though with overclocking, but not sure what you are asking them in your email though.

    If you still do need help, sorry, please start over and give me your full settings you are trying and I can help

    Hey, yea still no reply. Message was posted 8/9/2009 19:05.

    It's not overclocking per se but I suppose some may try to get out of it claiming that DDR2 1066mhz RAM isn't an agreed standard (or whatever).

    Basically I wanted to run 4 modules of 1066Mhz rated DDR2 memory on the P35C DS3R. The mobo can handle 2 modules at this speed fine, but using 4 is unstable at best. I was under the impression the motherboard can indeed handle that, but perhaps I am misinformed?
