    Yeah, that's why I flashed with F10a.
    I'm having no luck with these sticks at 1066. I'm trying 800 now with loose timings, 5-5-5-18.
    I've tried different voltages, now I'm 1h 20 mins in memtest with 1.2 mch core and 2.1 on the ram. Not expecting much, I'm thinking of sending the sticks back and buy some Mushkins.

    Do memories work in dual channel mode (what slots did You put them in?). And what about the temps - when You touch CPU and NB cooler (if You can) - are they hot? If any of them is - this is the reason. /edit/: It is quite possible that any of coolers is not mounted correctly - then temperature of it is ok, but the device may be overwarmed (CoreTemp can easily show You operating temps of CPU). To check what's going on, try to lower CPU clock ratio to say 6 or 7 - does it make any difference in memtest?

    I tested both seperate and for now I have them in dual channel mode in slots 2 and 4.
    NB cooler is the larger one next to CPU right? I can touch it, it's a bit hot but I can hold my fingers on it with no problem.

    Heh, sorry to be so slow:) Just lower CPU clock ratio for trial and notice the changes. If this fails: does one stick of RAM work ok? What about 1st and 3rd slot?

    I've checked with Core Temp in Windows, showed cores at 35-37 idle. Around 49 at load. Im 2 hours into a memtest now, but if it will freeze I will try your suggestion and lower the clock ratio and try the "real" settings on the memory.
    1 and 3 might work, it's just that when I checked the sticks seperately I moved them around from slot to slot to see if anything changed and they just ended up there hehe.

    So all temperatures are normal: lowering CPU clock ratio won't help, I suppose. This seems to be a problem with RAMs. Any other MB You can check them with?

    Not really, but I'll probably just send them back if I can't get stable settings.
    I have to admit, it's a pretty good learning experience. Haven't done much in BIOS before this computer build.

    @ mv2devnull. Ya, I guess they should say a letter means beta specifically. As it DOES which you know correct? If not you do now.

    @ neshiren

    Did you ever look on your ram sticks to see the voltage specified on the sticker? If not you need to for sure.

    Try this, I see a few things you did not set which could likely be your issue.

    Please also disable Legacy USB Storage Detect in the Integrated Peripherals Page of the BIOS

    Update: Stable for 12 hours with following settings (on top of my head, at work now)

    To answer your questions, the sticker says 5-5-5-15 2.1V
    USB Legacy is off.

    I've started a run with
    System Memory Multiplier ..............: 3.20
    Memory Frequency (Mhz) ..............: 1066

    I think I can finally start using the computer now and start tweaking the settings lower until it starts to freeze and then tweak it up again.

    What settings in the Advanced Timing Control change the performance the most? I'm not doing any benchmarks, but it would be nice to know what the important settings are. I know lower is generally better but is there any of the settings I should concentrate on, as a start?

    Also what does these settings do?
    CPU Clock Skew (ps)....................: <<< 100-150ps
    MCH Clock Skew (ps)...................: <<< 200-250ps

    OK, So it looks like you just had timings to tight. Those loose timings above show that your ram is ok and works fine on that board then

    Well first thing I would work on lower is Static tRead Value, try for 7-8. Then slowly work on the rest as you have time

    As for the Skews. CPU and MCH also are known as CPU and NB PLL if you see anyone speaking of these anywhere.

    I am not exactly sure but I do know that trail and error with them are worth the time. Especially when using a quad. Here is a page I found with some mention to this >>>
    Everything you want to know about overclocking with a Gigabyte motherboard - Overclockers Forums

    And >>
    http://www.anandtech.com/mb/showdoc.aspx?i=3190&p=13

    I did have a page bookmarked that explained it more in depth (I Kow it is addressed in the Intel Chipset PDF), but I cannot find it in my 100 bookmarks. I will try to find later tonight for you
