Is that straight multi OCing Xman...no bclk OCing (because as yopu know touch BCLK and you screw with RAM and PCIe frequency)?

Have you run SLI without a bridge...to eliminate bad bridge......tried a 314.xx series driver instead of the 320.xx ones which seem to give a lot of people headaches (though I must say I have not had a problem on any of them) there is a new beta out 326.41.

And finally we come to your CPU ...the IMC and PCIe handling are on the same bit of the CPU if I remember right....maybe, given your RAM OC experience and now PCIe not being able to take the strain....you should be first in line for IB-E 😉

OC your bike for a month mate and then come back with a CPU instead of a lemon in the socket 😄

Yes Arne, bclk at 100, untouched, and multi at 44. How can I run SLI without bridge? My memory is at a very mild speed, half-assed loose timings, and sufficient voltage. I had the memory at much higher speeds with same or less voltage running and passing RB. No OC on video cards whatsoever.

Next round of BF3, I will try 125 strap at 2133. Never really could get my mem anywhere at 100, 2240mhz tops. 2395mhz and passing RB using 125 strap. All my good RB scores were at 125 strap and then up.

Actually you can run your SLI without a bridge, the performance will not be as good but it will be in SLi.

The fact that RB is passed but a graphic intensive game is not certainly points to the issue being a video one, however memory (system that is) is key to how your VGA performs with your system.

I think you are correct with the sys memory theory. I am 99.9% sure my GTX680s are solid. Could it be not enough voltage to dramm for 2133/9-11-9-27-1 at 1.65v? I would think if 2400mhz is spec'd to run at 1.65v, 2133mhz with half-assed timings should be a breeze.

And also as I stated in 1st post, 680s are at stock speed. No overclock on mem or GPU. I was under the assumption that gaming benefits more so with higher sys mem speed than tighter latencies.

BF3 runs butter smooth with everything at stock and graphics at Ultra on this system. I was trying to see if it would run with RB stable overclocks. Strange. From what I seen messing with RB to the extent I have, any clocks that pass multiple runs of RB should shred any game. Apparently not.

Regardless, I still hold RB as one of my tools to establish system stability.

As far as posting a higher score than the 842, I hoping to post an 850 soon. That I believe, will be the limit,n my 3930K's IMC.

This is not true. Both matter and depending on the game engine, its settings and the amount of VRAM available on the video card you may see situations that benefit the latencies more. But in general there is a balance. High latencies can cause frame stuttering or driver timeouts.

I'll also second Arne's suggestion and test with Metro which is one very heavy beast as the issue may be game (or game+driver) specific that manifests easier on certain settings.
On a last sidenote you may also have residual effects after messing with BCLK, specially if you were playing with skew settings in order to stabilize an edgy BCLK setting (debug code 01 even after reverting to stock BCLK is such an example). In that case you should drain the board from all power.

EDIT: Also if a minidump gets created could you post it here so I can take a look in the debugger?

Turns out my oc wasn't quite as stable as I thought it was

OK, so what did you have to do make it stable for those "true stability benchmarks like IBT, Prime, LINX, etc." ?

Are you aware that those are not stressing the graphics together with the CPU and RAM too?
