    Default ga-h55-usb3 issue?

    not 100% its the mother board or the ram but i tried the ram 1 stick at a time and it ran fine. anyways, my computer has been running sluggish lately so i checked the basic stuff and saw that my ram was running in half, 4gig but (1.96 in use). also this, http://img198.imageshack.us/img198/2646/92413957.png , i went into bios and it shows dimm slot 1 and 3 at 2048, enabled slot 1 2048 enabled slot 3 -, total memory size 2048. so somehow my slot 3 is disabled? i dunno how..what do i have going on here lol im not that awesome at computers haha

    this isnt mine but looks pretty much the same minus the extra stick of ram:
    GA-X58-UD3R Won't Enable 3rd DIMM Slot - Gigabyte - Motherboards-Memory
    says something about a bent pin but i havent touched the inside of my computer since i built it or cleaning with air only and only lately ive been having this problem. thanks

    i just saw that there is an update for my bios from f6 to f7, the latest version for my board. should i go ahead and flash the bios with q-flash? it claims to, "Improve memory compatibility"

    You are using the white slots correct? Just checking to be sure.

    Can you boot with a single stick in either white slot? You should be able to, if not there is a problem and it's probably bent CPU socket pins.

    If you can't boot like that, then you'll need to remove your CPU and take some pictures of the socket for us to look at.

    If you do that, please take the images in a well lit room with no flash and Macro mode if you can. Take a few from different angles.

    yeah i have the ram in the white slots for dual channel.

    ive booted with 1 stick in each slot and ive ran memtest86 and its came back with no errors.

    whats weird is that ive had this setup since september, 600w ocz / i5 750 / gigabyte ga-h55-usb3 / ripjaw 12800 @ 1600mhz / 9600g and i havent had a single problem, but now all of the sudden its running my ram in half. when i bought my ram it came as 1333mhz and i had to set it to profile1 in bios to make it 1600mhz. i realized last night that by setting it back to 1333mhz, my computer runs it at 4gigs of ram.

    any idea why it was fine before then all the sudden it stopped? should i just get new ram? 1333mhz feels lil slow

    Well it could be the memory itself still, can you test with any others, or buy a new set easily to test with? If you can get a new set and don't mind doing so that would be great, then you could test and have new memory at the same time.

    Since you can boot with a stick in either channel your pins sound to be fine, maybe it's just you need to adjust your voltages in the BIOS?

    What QPI/Vtt and ram voltages are you using? Set 1.66 for ram, and try QPI/Vtt 1.25-1.35 and see if that helps.

    im actually shoooort on cash so i cant just buy new ram right now, i believe its life time warranty? havent checked since i bought it though.

    ive never messed with the voltage stuff, im a little scared with that haha. im not that good at computers or bios..i dont know what QPI/Vtt is but i think the ram is 1.5?

    What is the exact model of your memory and I'll check what voltage it needs to be set at.

    QPI/Vtt is the memory controller voltage, if this is set to low by auto that can cause you to be missing memory.

    f3-12800cl9d-4gbrl

    so theres a setting in bios under power management, "qpi/vtt", just set that to 1.25 - 1.35 and im good..after you find the correct setting for the ram of course.

    QPI/Vtt is in the MIT page, then voltage control, same page as memory voltage.

    You are right, that is 1.5V rated memory. So maybe set 1.52 memory voltage, then try 1.2-1.35 QPI/Vtt until you set the correct memory amount.

    hello back..changed the qpi/vtt to 1.210V. then i changed the DRAM to 1.560V, this was the next option above 1.500V. then i set the ram back to 1600mhz and for now its saying 4gigs of ram installed and in use yesssssssssssss haha i just hope it stays this way, before it would say this and change within a few hours so maybe ill be posting later but thanks for all your help mr. lsd!
