I'd also test the cards for stability (With only one card installed and connect to the card) using afterburner or Furmark just to see if one of them act different than the other, or one gets much hotter than the other, ect

    And don't forget the single stick cold boot memory testing, as one iffy stick can cause any number of random issues on a cold boot, so I'd actually get started on that each morning with all other testing aside or in the afternoon/warm booting.
    I'll start the memory testing tonight. Do you suggest one graphics card, both, or none? Would you suggest using the x16 slot or x8 slot when I leave the graphics card in the system for the night?

    I've tested each graphics card with Furmark extensively when I was pushing the overclocking. Normally I don't run them overclocked at all and their temperatures are perfectly fine, not that I can see how it would make a difference at POST. I kind of suspect right now that the BIOS POST gets a bit unstable when the x8 slot is occupied. Back in the day before I had my 2nd crossfire card I used to run my only card in the x8 slot for better cooling.

    I wonder if the gigabyte BIOS creators haven't been able to replicate this problem because they use the built-in graphics when they do their testing. Maybe the instability requires a high-end external card to be present in addition to other factors, such as an excess of RAM. I do think that the gigabyte BIOS defaults to a QPI/PTT voltage that is too low by default, 1.05v.

    If it turns out that the board is unstable with the x8 slot occupied I'll probably just sell my cards and get the GTX 680.

    I'd stick with one card for now, where ever it seems to not give you issues.

    QPI/Vtt, that all depends on what memory you have installed, I'd say if it's not budget 1066-1333Mhz then yes, you probably need to increase QPI

    It's been about two days now and when I'm using my Sapphire 6950 unlocked I've never had a problem, even cold booting and using 16GB of RAM, but when I've used my MSI 6950 unlocked I've had several problems. This seems to be graphics card related, which is exceptionally odd.

    Great to hear you've narrowed it down some now!

    So maybe the MSI card is somehow damaged, or their is a BIOS incompatibility. If it's a BIOS issue they'll need to know the exact card model so they can try to replicate and then correct.

    Do you know anyone close to you that has the same card? That way you could verify if it's your particular card that's causing this, or the model as a whole.

    I really doubt the MSI card is damaged as it runs perfectly fine in Windows, can game, can overclock, everything. It's not like the graphics card should even be involved in the POST process. Anyways, I've been running with just my Sapphire 6950 for the last few days and everything has been completely stable. The F7 BIOS must have done something because on my old board, even with my Sapphire 6950 I still had boot loops. When the F7 BIOS came out I was already Crossfired so I never tried F7 with just my Sapphire 6950 until now.

    Unfortunately, I know no one with a card that I can try.

    I will sell both of my graphics cards and move on to a 7970 or Nvidia 680 since I suspect this board just has crossfire issues and I would like a single card solution that can handle eyefinity.

    It's probably not as you mentioned, maybe a BIOS incompatibility? You can send in a report and ask them to try to test with the same exact card and see if they can fix it in the BIOS.

    Single card upgrade sounds like a good move if you already have the spare $$!

    Hi all,

    First off here are my hardware specs:

    - I7 2600k on a Z68-UD7 (CPU water)
    - gainward gtx 570 phantom (water)
    -2 x 4gb corsair vengeance 1866 @ 9-10-9-27-1T
    - 120gb vertex 3
    - 1 tb Samsung spin point F3
    - corsair Ax 850 psu
    - creative titanium hd sound card

    CPU temp after 1 day of folding = 60c
    Gpu temp = 43c

    I have this annoying boot issue when overclocked.

    When my CPU is @ 4.8ghz (2600k) it's fully stable for 48hours On prime 95 and can fold for days on end.

    Settings are 1.375 with LLC7 so on load I get 1.392vcore.

    It's all good when the rig is on. But when i switch the rig on (btw its still plugged in and has power running through it, the Rig is just switched off) it would get stuck on C1 (led poster) and flicker a few times then reboot, it does this a few times the. Eventually loads up with the OC settings still in place.

    The CPU is watercooled and on boot up it would sit at ~29c idle and 60c on load (after a few hours of stress).

    I have the F10 bios btw and on the backed up bios

    I have replaced all my previous corsair dominators===stil no fix

    Can anybody help me on this?

    It happens EVERY time I boot up and the OC never fails...

    Thanks

    Firat

    It's best to put your hardware list in your forum signature where we can quickly see exactly what we're dealing with.
    Keep in mind that most of the active members responding to your post are also assisting in many other threads where the OP has a somewhat similar hardware setup. This will help prevent possible mistakes.
