And, I'm back to this. Woohoo.
I think I have narrowed it down to GPU RAM (yes, I've said this before...). The reason I say this is that my system is now rock solid stable, except when attempting to run Collatz and/or upping my RAM clocks. I'm currently running at 825/600 on MW (stock being 725/1000). Stable as hell. Temps great, no hiccups or lags or anything. The second I crunch a Collatz WU, or just a few seconds after upping the GPU RAM clocks, I get this:
When I run the "Test Custom Clocks" function from CCC (even with stock settings this happens), I get this:
I have used ATI OverVolt to adjust RAM voltages, but that has a minimal effect, and resets itself after a computer restart anyway.
Any ideas, or should I continue punching myself in the nuts?
I hate to be a naysayer but it could be a PCI-E bus problem. Your MB might be at fault here.
Joker has a good point there. The bottom line is you need another system for testing or at least an equivalent GPU and PSU (Known to be good) to swap into your system for comparison. What about taking the funky system or one of the GPUs to work with you and use one of the lab boxes for a test bed?

Good news: It's not the motherboard/PCIe slots.
Bad news: It's the video cards.
I took the cards in to work, and tried them out there. Same error, same artifacts, same issues. Happened in combination and when I only put one card in at a time.
Harley has been a champ, and has been PMing me a ton of ideas on how to fix the cards, but I've had no luck so far. Am I at RMA stage, or are there other things I can try? It's weird to me, because these cards work great on MW, but freak out on Collatz.
This is now out of league. Good luck.
I'd take the RMA route if the option is there. I hope they're not Sapphire's, I had an awful time with them recently on an RMA. I think you would have the same problem with MW if their work units ran longer.
Oh yeah, I forgot. You've punched puppies, kicked children petting puppies, and punched yourself in the nuts, but have you kicked a kitten yet?

You might have to go to your local petting zoo and kick some goats and sheep in the nuts.
I think its time to grab the Bull by the horns, the Tiger by the tail and kick them both in the nuts.
