    Question GA-MA78GM-S2H / AMD Phenom X4 / Corsair Lockups

    Can anybody please help me? Iím having a nightmare building a new box with the following spec:
    Motherboard: Gigabyte GA-MA78GM-S2H
    Processor: AMD Phenom X4 9750 (2.4 GHz)
    Memory: 4GB Corsair TWIN2X4096-6400C5 G
    Hard disks: 2 x Samsung HD5021J Spinpoint 500GB SATAII
    DVD: Optiarc AD-5200A-0B
    and a Sony 3.5Ē floppy drive
    <o:p> </o:p>
    At first I had to clear the CMOS every time I rebooted but that seems to be less of a problem now (I updated the BIOS on the motherboard to F5 which may have helped). My main problem now is that I get lockups after a relatively short time of use - around 30minutes - and then subsequent reboot result in lockups before I can even login. Not sure if this is relevant (or helpful) but when it locks up I get a slight corruption of the image on the screen (short vertical lines) Ė looks a little like interference.
    Iíve run a memory check (memtest86+) which gave the memory a clean bill of health.
    <o:p> </o:p>
    Suggestions of things to try would be very welcome as Iíve run out of ideas (having spent a couple of days reading forums and experimenting).
    <o:p> </o:p>
    Thanks in advance

    I do not know much about AMD, but I can tell you with 4GB you need to add Memory controller Voltage and set Refresh to act delay (trfc) as high as your board will allow (54+ is needed, some allow this some do not). And be SURE your ram voltage it also set to 2.0-2.1V (Likely your ram spec on sticker right?)

    Here is OCZ not about this, Corsair I am not sure about if they will help you or not >>>
    The importance of tRFC and 4/8GB of memory - OCZ Forum

    If you do need me to get you a tool to change your SPD Value for trfc (If your board will not allow a high setting) let me know and I will provide you a link. WILL Invalidate your warranty

    Thanks for the advice, it is very much appreciated.
    I'm a little confused over the trfc setting. I've looked in the BIOS and I seem to have options of 75, 105, 127.5, 195 and 327.5 - I don't seem to have the values that you and others have quoted. Am I being a bit dumb here and am looking at the wrong thing?
    I've tried various combinations of trfc and voltage but have not found one that seems to improve matters. Some combinations result in either a complete failure to boot at all or they hang during the POST.
    Thanks for the offer of a tool to change the SDP (I'll have a read about what that is and get back to you if I decide to go down that route).
    I'll have a go at a few more permutations to try and narrow this down a bit.
    Thanks again for trying to help

    Ya, Intel and AMD are different, that is the correct setting. I just did not mention it that way because not all AMD boards have it written like that either.

    127 or less is the normal for 2x1, so I would think you should set 327.

    Good luck, and let me know how you get along. Hey, have you asked the RAMGUY, Corsair Support forum for settings? >>>
    The Corsair Support Forums - Powered by vBulletin

    You may be able to get some more direct answers there.

    Thanks once again. I'll try RAMGuy at Corsair and see if he can help out. I did try 2x1GB in the box and it ran all afternoon without skipping a beat.
    Cheers.

    Ya, it is just 2x2 needs some tweaking for sure. Let me know if the Ram guy is of now help, Ill look up your specific ram and find some others settings for you

    Great, if you find anything out do let me know.
    I've started a thread over on the Corsair site (with RAMGuy), if that leads to a solution I'll post it back here as well.
    Thanks

    I did find you a 100 Page thread about your board >>>
    The Official Gigabyte GA-MA78GM-S2H RS780 mATX Thread - AVS Forum

    Maybe that will help, I would imagine you can find tons of settings in it

    I did just see he suggested just that to you! I suggest you ask him directly what trfc setting you should use, this is the issue most of the time.

    Aside from the above link, here is a Few forums that have AMD Specific sections where you should get a more clear answer about general AMD 2x2 trfc and other settings >>>

    Overclock.net - Overclocking.net

    Thumbs up Re: GA-MA78GM-S2H / AMD Phenom X4 / Corsair Lockups

    Thanks once more for the reply and the links - I'll take a look at them tomorrow when I have more time. It's really funny that you are following the thread on the Corair site and that you predicted that they'd suggest running the memory more slowly (i.e. at 667). The setting they provided have left me with a working machine for which I'm grateful (I'll list their suggestion here too for completeness) and you are right that it is disappointing. After all, if you bought a Ferrari you'd not expect to be told to keep it under 100mph when the marketing blurb says it will do more!

    The suggestion (which worked) from RamGuy:

    MB Intellegent Tweaker

    DRAM Configuration = Enter

    tCL (CAS Latency) = 5T
    tRCD (RAS to CAS R/W Delay) = 5T
    tRP (Row Precharge Time) = 5T
    tRAS (Minimum RAS Active Time) = 15T
    1T/2T Command Timing = 2T

    Leave all other Memory Timings to Auto

    CPU Clock Ratio = 12X
    CPU Host Clock Control = Manual
    CPU Frequency (MHz) = Set to 200
    Set Memory Clock = DDR 667

    System Voltage Control = Auto
    CPU Voltage Control = Auto
    DDR2 Voltage Control = +.2v
    CPU Spread Spectrum : Enabled (I didn't find this setting)</pre>
    Thanks

    Spread Spectrum, do you have the latest BIOS for your board? If so, then on the MAIN page of the BIOS hit Ctrl + F1 and the screen will flash, then go into MIT and see if you can see it as it may be a hidden setting.
