    I just checked and mine was on auto, and auto defaults to x19..

    Would lowering it decrease performance?

    QPI PLL, often auto is fine many say but I have no luck with that at all. I find, depending on QPI/Vtt and overall speeds that 1.18-1.28 works better than auto which most always stays at stock. Try 1.20-1.24 QPI PLL and see if it help any before lowering your uncore.
    I played with the QPI Pll a bit yesterday, and I went up to a maximum of 1.4v, but it had no discernible impact on my stability.

    So you ram was at 1640-1650 right? If so, what main timings were set?
    Timings were 6-7-6-15 CR1. The memory is specced to run at 6-7-6-18 CR2, but I haven't had any issues running with more aggressive timings.

    I just tried different uncore multipliers, from x18 down to x16 and still, the same problem occurred..

    I've just about had my fill of this! There's hardly a setting that I haven't touched or altered and none of them had any impact.

    So I just turned on turbo mode, and I'm at 4.2ghz stable no problems. Increasing the bclk over 200 ends up with all sorts of stability issues however, regardless of what I do it seems.

    Like I said in my first post, I've heard some Gigabyte boards have issues (individual boards) running over 200 bclk, so I may have gotten the luck of the draw.

    So I'm done playing with this thing, and now I have to decide whether to exchange it for a UD7 or some other board, perhaps a ASUS P6X58D Premium.

    Both of those boards have USB 3.0 capability.

    I doubt auto Uncore is x19, it just looks that way in the BIOS (I know what you mean) CPU-Tweaker would show you different if you checked.

    So turbo is what helped? Odd to hear, as this always caused problems in older boards, but I did see this help as well with a P55 user the other day. So maybe this is becoming the norm for the new boards? I better keep an eye on suggesting this to standard, and maybe do some testing of my own which would be hard for me because I know what should be what HAHA.

    I always use Extreme on that setting myself, have never used anything less actually even at 5Ghz or 2100+ Ram speeds.

    I have never seen or heard of a board itself having 200+ Bclk issues, this is CPU Dependent as the boards will all do 222 Bclk with ease if you have the right CPU and 240+ if you mod the board.

    If you stick with UD7 you will have my support If you switch teams I doubt you will find as much help with things.

    All up to you though, good luck in deciding. I really think your board now is fine, you just need to find the right settings is all. Sorry I can't stop by and have a beer with you and fix it, that would make things so much easier on you

    I meant turbo mode, you know the feature that changes the multiplier, and not the turbo from the performance enhancement.

    For that, I always use Extreme

    Maybe you're right. Maybe it's not the board, and instead is the CPU. Of course, I have no true way of telling unless I put this CPU in another board.

    This is my first Core i7 platform, and if there's one thing I've learned, overclocking can be quite a bit trickier than the Core 2 family was.

    Ohh!

    Sorry about Turbo then, I also only use Extreme!

    Ya I do not think it is the board at all, maybe the CPU, but that is unlikely as well. Most can do 200+ easy, some of course take more work than others though. The boards are very strong though, I have a few and a few CPU's and they can all do 235+ Bclk.

    Yes, i7 is a new beast to learn. Right after learning how to tame the P45 Beast! :)
