Hi all, I received my new VTX7870 today & was just doing a quick 5 minute test of Far Cry 3 when I got a BSOD with the following:

dxgmms1.sys
Page fault in a non paged area...

So this looks like a direct x issue but I'm wondering if its possible that my overclock is not that stable. I'm running my i7 920 @ 3.8Ghz (but only since yesterday) so maybe that's the issue.

I was using the latest drivers & latest motherboard BIOS.

Anyone had this error? :(
 
I had been running the PC at 3.6Ghz for a while. I don't think it was as stable as it could have been - every now and then (although not that often) if would reset itself to defaults so there is obviously something I'm missing. I had been running at stock for quite a while more recently but when I bought the new GPU wanted to give the CPU a boost! I've tested the RAM (in fact about 18 months ago the RAM was replaced because it was faulty) & it tested fine.

Any suggestions much appreciated, I'd really like to get a little more from this CPU.

Added my rig in my sig but as its not showing up yet here it is:

Just to report back on progress. I upped QPI/VTT a little, ran OCCT for about 10 minutes and got a BSOD.

I was thinking it might be worth increasing the RAM voltage so changed that to 1.56 (from 1.5) & upped QPI/Vtt a little more. Ran OCCT again and this time it ran fine for 30 minutes. Need to test for longer though. My CPU temps were around the 65 mark during testing. (Max)

Here are my voltages. Do u think they look ok? Is the RAM voltage safe to run at 1.56? Also, is OCCT what I should be using to test - been out of the game for too long so not up to speed! :cool:

Ok, so I set CPU voltage to 'normal' and then went to PC Health Status (presumably this is where u mean to check the voltage) and it's saying Vcore is 1.284.
 
Cool. Running OCCT now and keeping an eye on CPU-Z voltage which is fluctuating between 1.248 and 1.264 (at the moment). Will leave it running for a while.

Core speed (presumably because of turbo boost is showing as 3.779.93Mhz)
 
At idle, core speed is jumping from 2160Mhz to 3779 and voltage is also jumping between 1.056 and 1.248. The only power saving left off in Bios is C1E.

Looking again at core speed its mostly running at 3779.
 
Great, many thanks. Might leave c1e off for now and see how it goes. Will try for 3.8 but it's so close now that should be fine all going well and as u say I can add a little more dvid if necessary.
