    Default Unstable system with GA-Z68X-UD3-B3

    Hi friends! I need some help. This week I build my new system:

    CPU Intel Core i5 2500k
    Motherboard Gigabyte GA-Z68X-UD3-B3
    Memory 2 x 4Gb Geil Enhance Corsa
    VGA eVGA GTX570HD
    PSU Thermaltake Toughpower XT 775w

    I'm getting some BlueScreen at windows and freezes in some games like Bad Company 2 and Starcraft 2, so I made some tests to try find the problem:

    In all tests I used stock values with Load Opt in bios. In all tests I don't have any temperature issue, with max 56 celsius. Follow my tests:

    -Test 1: 2 x 4gb RAM in slot 1 and 3 (Dual channel) -> unstable in prime95
    -Test 2: 2 x 4gb RAM in slot 2 and 4 (Dual channel) -> unstable in prime95
    -Test 3: 1 x 4gb RAM in slot 1(modulo 1) -> unstable in prime95
    -Test 4: 1 x 4gb RAM in slot 2(modulo 1) -> stable in prime95 for 2 hours
    -Test 5: 1 x 4gb RAM in slot 3(modulo 1) -> unstable in prime95
    -Test 6: 1 x 4gb RAM in slot 4(modulo 1) -> unstable in prime95
    -Test 7: 1 x 4gb RAM in slot 1(modulo 2) -> unstable in prime95
    -Test 8: 1 x 4gb RAM in slot 2(modulo 2) -> unstable in prime95
    -Test 9: 1 x 4gb RAM in slot 3(modulo 2) -> unstable in prime95
    -Test 10: 1 x 4gb RAM in slot 4(modulo 2) -> unstable in prime95

    I done test with memtestx86+ with both modules for 3 hours with no erros.

    I really don't know what is happening. Maybe a incompatibility memory and motherboard?

    Please help me...I'm lost...

    Thanks in advance!

    What is the exact bosd stop error message? It would look something like 0x000000124 or 0x000000101. You may need to tell windows to not reboot on error if the system reboots before you can read the error.

    Most likely you may need to increase vtt voltage. Loading Optimized defaults is a good start but you still need to configure your memory settings and voltages.

    Please post your full bios settings that you are currently using that are failing. You can find a link in my sig for templates to use/follow. Also you will see a link for bsod error codes and their correction. You may want to print that out to help while getting the system stable/overclocking.

    Thanks for reply Acebmxer!

    About BSOD code I'm getting most of times 0x0000001a. But not always I gave BSOD, mostly I have problems of stability, detected with Prime95 tests.

    I will post my full bios settings here later when I go home but I believe most is default/auto.

    Yesterday I made some more tests with a DDR3 from computer friend. With this memory, I ran prime95 for 3 hours with no errors, so I concludes my RAM is the problem, not motherboard because my Geil memory in my friend system crashed prime95 after 2 minutes. I'll send it to RMA today.

    Thanks for help!!

    Hi guys, i have a Z68X-UD3-B3 with 4 gb A-DATA 2133 XPG gaming series v 2 and when i set from bios to the 2133, the sistem is booting but after 10 or half our i get a blue screen.
    I wanna know if the memory and mb are incopatible or i dont know how to set the memory for 2133.
    The blue screen looks like that: http://img98.imageshack.us/img98/1453/img0474im.jpg

    @softerist
    You need to set not the frequency, but also the timings and memory voltage as specified by the manufacturer (on the sticks or the package).
    If you still have problems try to increase VTT gradually from 1.08v to 1.2v.
    Can you please attache a CPU-Z text report(CPU-Z -> About tab -> Save Report (.TXT))

    Thank you for your quick response.

    I've tryed to set manually the timings from the memory manual but didnt work at all, the pc keep retarting with overclock errors, so i've done a video of the setting wich the windows boots but give me a BSOD after 10, 15, 20 minutes.

    So, I have UPLOAD the video of my BIOS settings wich i get the BSOD, and the txt file from CPU-Z.
    Olso in the video descripion are the details of the memory.
    Watch the video and the txt file and then tell me what sould i do.

    Thank you so much.

    P.S. I apologies for my bad english.
