My PC runs very well in games. About 80 FPS in most games maxed out on a 2k display.

The issue is that I get constant (3 times a minute or more) of what act like almost mini lockups.

On GPU monitor I see that when the lock ups happen, GPU load drops down to about 60% on both Titans (or just one of the Titan's) or sometimes even lower, and the FPS according to Fraps goes to hits 40 or lower.

What I have tried with a little bit of success finally is increasing the minimum voltage to 1000mv. I noticed that voltages dropped down with the above drops.

When forcing it's minimum to 1000mv, it will now stick at 1162mv without failure.

There are still a few drops but now it is better.

The drops seem to be worse on the second GPU not sure if that is yet relevant but I will test that one on it's own tonight.

Any advice for testing would be welcome.

Drops don't happen in furmark. IT will go down to 31FPS on the benchmark, at full settings but there are now random drops. (Seems to occur mostly on Crysis 3 and Titanfall.)

I have also posted this issue again with new findings to help anyone else with the same issues, so apologies to the moderators if I have been posting too much recently about the same subject.

I will do HWinfo ASAP.

Guess what though.

I was experiencing COM surrogate issues whilst going through folders on one of my drives.

I was thinking that doesn't seem right. So I downloaded a fresh ISO of Windows 8.1 and put it on USB with RUFUS.

I re-installed all games and graphics driver from fresh.

And the result shocked me (as this issue has followed me from Windows 7 64 bit to Windows 8.1 64bit) The mini hard locks have stopped.

I feel like such a noob. But as I said above this isn't the first time I have re-built this system to attempt to fix these issues.

I will still post HWINFO and I am only cautiously optimistic at the moment (Tested Crysis 3 and Titanfall and works flawlessly).

I am sorry that I wasted your times...

I'd start with looking at system sensors for basic info. Can you download and run HWinfo, run sensors and post screenshots here? It will take a couple of screenshots to get all the system sensors. If all looks good there, we can move forward to other diagnostics. Also, prior to that, I generally recommend a fresh install of the drivers after uninstalling using the Display driver uninstaller, even if you've uninstalled, reinstalled, installed sideways or otherwise tried various driver versions.

Run the DDU and then install the latest drivers.

Thank you so much for your advise. I will try this As soon as I can get to my PC.

Also I will of course try the drivers again, as I do not want to rule out something you said, but this issue has followed me from a Fresh build of Windows 7 64 ultimate to a Fresh build of Windows 8.1 64 bit, so I am pretty sure it is hardware specific.

To update as well, I tested cards individually on Crysis 3 and Titanfall:


GPU 1 in PCI Express slot 1: FPS Drops
GPU 1 in PCI Express slot 3 (the other x16 slot) : FPS Drops
GPU 2 in PCI Express slot 1: FPS Drops
GPU 2 in PCI express slot 3: FPS Drops

Tested on Firestrike Standard: Both cards no FPS drops. GPU 1 scored about 100 points higher
Tested on Firestrike Extreme: Both cards no FPS drops. GPU 1 scored about 100 points higher

I am wondering if it might be worth getting another rig with at least 1 - 16x PCI express slot to test if it drops with Crysis 3? If they don't experience drops in the other machine then it could suggest PSU/CPU/RAM issue?

Again really appreciate your time!

You might need to RMA the card or cards, call Asus @ 1-812-282-2787 and go through the trouble shooting steps with them.

I am sorry that I wasted your times. (But at least this way if someone else experiences these issues they can try this themselves and it might solve their issues as well)
