    hi yes sorry i should have said before, im overclocking these are the o/c settings

    i7 930 Bloomfield @ 4010mhz v-core 1.200 x 21 191mhz
    ram, Patriot Viper 1600LL series 6x 2gb tripple channel timings are set @ 8,8,8,24 DIMM 1.648 - not sure if thats the same as the dram voltage trying to read there in ADIA withing windows, (please say if its wrong) 12gb ram total

    i have tryed with out any o/c by loading fail safe in bios and also optimized all with the same resaults wich brout me to think its nothing to do with the o/c
    max temps im getting under full load is cpu never hits 70c gpu 1 71max and gpu 2 68 max

    it still could be not enough qpi/vtt,esp with 12gb of ram,for stock clocks on x58 i needed 1.3750v qpi with 12gb @1600mhz,and even at default settings auto doesnt always set the voltage right

    you might need between 1.3750-1.4v qpi/vtt,you can use upto 1.45v+ safely but im guessing youd only need around 1.4v mark

    any blue screens when it freezes? 124 error blue screen means not enough qpi/vtt voltage,101 error means not enough cpu voltage

    i have now set the qpi/vtt to 1.395v and it is now in pink, the v-core to 1.23750v and in UNIGINE heaven bench mark it is still freezing up the stsyem at random points, this morning i ran a total of 9 heaven bench marks with diffrent settings for the qpi/vtt and v-core none of the settings get it stable but i have installed 3d mark 11 and furmark and it isnt crashing or freezing (yet) in either of these two bench mark programs, it has froze once on the desktop today so far, i dont really know much about the programs but at a guess i would say that furmark is the most intensive out of the 3

    all the time its been doing this i havent yet had any blue screens just freezes iv tryed waiting incase it un freezes but always need to hit the reset switch.

    im very greatfull for all your help so far, thanks

    Your core voltage at 1.2v seems low for 4.0 oc, should be in the range 1.3-1.35volt.
    When stress testing your 6 dimms full of ram,that 1.648 volts may drop to about 1.61-1.63 stressing it(freeze)
    I would raise it to read 1.65-1.66volts in windows ( 1.66-1.68 in bios )
    vtt- 1.35-1.4v

    i have now ran 3d mark 11 loads of times cant chang the settings as only the free version but i have had no freez ups while running it, i have played ghost recon future soldier for well over an hour all settings maxed right out and again with no problems at all, Heaven benchmark is a totaly diffrent story, still freezing at any random point sometimes after a beboot i can ran 3 to 5 benches in heaven before it freezes other times after a reboot it will freez on the first, i changed all the settings in heaven to there max and it ran that 3 times in a row without freezing or crashing, very weird, also 3 times now in the past 5 days while opening GPU-Z the whole system will freez up not happend yet with any other programs, when i get a freez it will either turn the screen off like into power save mode or it will just freez with the picture still on the screen till i hit the reset button, no other screens, no blue ones and i know what you mean by random colors, no i havent had any of tham,
    about my o/c and v-core, i can run either prim95 or the intel burn test for how ever long with no problems at all.
    right now i have still left the settings for qpi/vtt @ 1.395 and v-core @ 1.23750 in bios
    this is just a thought but i was thinking maybe force both gpu's to the bios of the first card i had the GV-R685D5 rather than both on the newer ones bios the GV-R685OC

    try underclocking both gpu memory clocks by 150mhz,then test with heaven benchmark,could be gpu memory thats causing crashes

    thanks wazza300 i think thats it, i had to use msi afterburner to underclock the gpu memory as ccc doesnt allow for underclock only for the core, i took it down to 900 fist like you said - 150, it worked sevrel times without any problem at all so i started to add to the memory clock a little at a time till i got all the way back up to 1050 again, @ 1037 it is fine i ran 10 benches in a row with no problems then rebooted then another 10 benches in heaven and again no problems no freez ups, anything over 1037 i will freez within 5 benchmarks.

    one thing i dont understand at 820 core and 1050 memory my scores in heaven are (when it doesnt freez) FPS 93.9, SCORES 2366, Min FPS 41.0 Max FPS 181.2 but when set to 820 core 1037 memory i get FPS 97.9, SCORES 2466, Min FPS 34.5 Max FPS 181.7 as you will see lower memory clock higher score, thats just wrong to me, does this mean my problem has gone or is this the answear to what the problem was or is ? does this also mean its as far as my gpu's can go ? i have seen others that o/c there 2x hd 6850's to well over my clocks, like 950 core and 1150 memory

    thanks again for all your help getting me through this

    some cards throttle the memory to stop crashing,i know on my 7850 its the same,performance actually drops off once you pass a certain memory clock so its best to find the limit,i think it was your gpu memory causing the crashes,my old 5870 did the same till i reduced the mem clock,then it was rock solid,you can try setting cpu and qpi/vtt back to what you had before and see if its still stable
