ATIKMPAG.SYS BSOD, Why?

Hello good people of TH, I'm back with another problem which seems to be related to ATI/AMD :pfff: 

So it all started a few days ago when 3DMark11 came out, I downloaded it and decided to run the benchmark with both my HD5850's at 1000/1200 @ 1.275V, The benchmark finished and there was peace in the world but I forgot to print screen the results :fou: 

So I re-ran the benchmark but this time received a BSOD :(  I then tried 980/1200 @ 1.299V but received another BSOD. I then tried 950/1150 @ 1.299V and received yet another BSOD.....

The next day I decided to play around with the Metro 2033 Benchmark, I first ran it with both cards at stock and it ran perfectly, I then tried 775/1125 @ stock volts but got another BSOD, Which is very strange as I know both cards are stable on stock volts upto 910/1220...

Oh BTW all these BSOD's have ATIKMPAG.SYS which I believe is related to the ATI Driver

It was suggested to me by a friend that I should check that my CPU overclock is stable, So I Ran OCCT @ my usual 4Ghz and 1.32500V, This produced a BSOD after about 25 minutes :heink:  I then ran it at 3.8Ghz with 1.32500V and received yet another BSOD this time after about 5 minutes...
Yesturday I ran OCCT for almost 7 Hours at 3.6Ghz and 1.32500V (1.294V in windows under load)

However during this OCCT run at about 6 hours the ATI driver stopped responding but then recovered... and 15 minutes after that MSN stopped responding, but also recovered.....

This morning I booted up my PC and after about 10 minutes of browsing the web I received a BSOD (fml) still containing the ATIKMPAG.SYS, I then reset my CPU overclock back to stock and rebooted but my PC wouldn't post... I pressed the restart button and it posted this time giving me a warning about my overclock not being stable (at stock??? :heink:  ) Oh BTW I put my RAM to its rated timings/voltage/speed when I reset my CPU's Overclock.

I haven't had a BSOD since resetting my CPU back to stock (lucky me)

I've done some research and this is what could cause a BSOD with ATIKMPAG.SYS:
* Insufficient power
* bad Memory module
* OverClocking
* Motherboard/Memory Compatibility
* Overheating
* Defective Motherboard
* Wrong Drivers
* Bad PCI-E Slot


Sorry about the ridiculously long post... :pt1cable:  All help will be rewarded with a ;)  :lol:

Maybe 3D Mark 11 was too difficult for the 5850s to handle. :) 
I would try running each of those card separately and also trying out different slots.

The 5850's managed to run it once at 1000/1200 @ 1.275V but failed at a lower overclock with more volts...Which doesn't seem logical at all.

3DMark11 won't push my cards any harder than any other benchmark or game that pushes my cards to 100%

It would be a real PITA to run the cards in different slots as both are watercooled and so would involve draining my waterloop, changing the cards position and then leak testing for atleast 8 hours. ;)

Does your card run fine at stock speeds ?

Don't know, I've had BSODs when both cards have been at stock but i'm unsure whether this was caused by a unstable CPU or by the cards or the ATI/AMD Driver.

EDIT: I haven't had a BSOD since I reest my CPU back to stock which would suggest the CPU has been causing the BSODs, but the BSOD always Contains ATIKMPAG.SYS which is ati driver related/

Hmmm.....

Are you sure that your water cooling is working properly?

I'm thinking its more to do with my CPU not being stable, Can't even get into windows at 3.4Ghz anymore.... I've created a new thread in the Overclocking section about this.

And yes my watercooling works fine, CPU didn't go over 57C under OCCT @ 4Ghz with 1.32500V and my cards stay under 34C under load.
