Ok... my PC is stable, been running in Prime95, memtest, linx for 2 weeks now without one single hickup... so i can declare my new build with a light overclock to 4.0ghz on an air cooler. I had to run the memory timings manually instead of XMP, with EXACT SAME settings... i dunno why when i run XMP i get the 12x overclock failed msg, and i don't get that problem when i input the timings manually.... anyway... bottom line, it works and it's stable.
Now... the only left problem, is the video lost signal... and i ran down one last test, that seems to lead me to a problem with the OC Key. As i was running my benches with Prime95, linx, memtest and some gaming... i saw the video signal loss for 1-2 sec constantly, but randomly... could be without one single drop for over an hour, but then, 3-4 drops in like 5 min....
I then proceeded to remove the OC Key and plug in my DVI cable directly in the videocard, and... never saw a signal drop anymore...
I would like to remind that i was, since i build the rig, experiencing video signal loss on a random scheme...
I am now running 0018 bios like 2 weeks ago, and this is the one i am running with small 4.0ghz overclock... system is totaly stable, got like 2-3 runs of Prime95 for 8hours straight without any problem, i can do gaming as long as i want without problems and i can sleep or hibernate without problem... stable for a 24/7 rig... beside the video signal loss...
Now, it's a video signal loss, as the driver doesn't fail... it's only that the screen blacks out for like 1-2 sec, and when it blacks out, i get the picture of my DVI port on the top left of my Dell 27 inch monitor, leaving me informed that the monitor loss it's DVI input signal... (i did check with a remote destop with VNC and when the blackout occurs, only the monitor loses the signal, the remote VNC doesn't move a tad, and i don't get a video driver failed.
Needless to say, that the only thing that sits beside my crossfire setup of videocards and my monitor is the OC Key and my DVI cable... i did swap the video cards to see if it would change anything (as i am using crossfire)... to see if it was one of the videocards but the problem stays whatever the videocard is in the primary slot... so it couldn't be the videocards themselves... (since swapping them resulted in the same problem ans since i tested remote desktop to see if it's a driver issue)
Last thing i said i was testing was to remove the OC Key from the loop, and everytime the OC Key is out... i don't lose video signal anymore... Whenever i put it back... the video signal loss problem comes back...
What would be the next step? I can't test the OC Key on another computer as it woudn;t be plugged... so i think this is out of the loop... could i?
I flashed my OC Key with 1003 firmware, and i don';t think there is another one... so i am out of options here...
Should i RMA the OC Key? I would like to make sure it really is the OC Key that is acting up...
I am running my computer at 1920x1200 which is my native LCD monitor resolution (Dell 2709) and also happens to be the max resolution the OC Key supports... so it should work... but it seems to be the cause of my signal loss to my monitor... any idea?
