I've run driver sweeper twice even did a fresh win 7 install. Issue is every time I try and load any game the driver crashes and crashes the game or crossfire crashes crashing the game. I apologize for the fanboy commet I'm just extremely frustrated.

You have major issues with your PC if this is true. And that's a big if.

Tell us more, how do you have 12gb. Is that 2-2gb and 2-4gb?

With just 2-2gb on my computer, I have to run the ram at 1.66v and 1.68v with faster speeds/timings. That is with 2, -smaller dimms.

Sometimes odd configurations, result in more stubborn tuning/stability.

yes that would be correct but they are coming out in favor of a pair of 2x4 2133 dims

I would be laughing my ass off but I can't believe people don't stability test their over clocks properly. I blame the reviewers going off and getting 5Ghz over clocks at 1.5 V on specially donated hardware when we all know that is not 24 hour stable nor is it likely the chip will survive long at that level of torture.

Why does GPU use affect your over clock? Because it uses different instructions, uses more memory bandwidth and the pci-e interface, none of which was tested by your benchmark program. What we actually need is a program designed to test all the x86 instructions in a variety of ways to teat the CPU stability. Intel must have such a thing actually.

"AMD drivers destabilized a CPU overclock" I'm not sure if I want to laugh, or if the OP really believes something this utterly ridiculous. Are you really this...I won't even say the word. This is perhaps the most hilarious thing i've read here yet, people don't do proper stability testing and then blame the hardware for not OCing as high as they would like. Especially a GPU driver which has no effect on the CPU overclock.. I guess laughing is the most appropriate response to the OP.

Thought it was more or less proven that your PSU is inadequate or that your cpu overclock wasn't stable when you added a beast of a video card to the sytem. You probably only had to add a little more juice to the cpu but apparently intellect isn't everyone's strong suit.

I was wondering what this thread was then I saw it's the same thread and the user has just decided to change to another false title.

Your fail at ocing doesn't have anything to do with drivers. Second fail of a title.

Learn to test for stability. It was hard enough to get it through to ease down the unstable oc for testing.

by fail of over clocking ability would u be talking about the 5.2 ghz daily stable oc i had with my nvidia card and 2500k combo?

A GPU has no effect on CPU overclock-ability. Whatsoever. You either have no idea what you're doing or no idea what you're talking about. Period.

You really should get rid of the 7990 and go back to nVidia. You've been too brainwashed about AMD drivers to ever be satisfied with your purchase. You insist on blaming the drivers. Just my opinion, of course.

> Why do amd drivers destableize previously stable OC

Answer: They don't. Your OC was not stable.

Jesus guys, lay off a bit okay, FFS, everyone having a go at the lad is not cool, no matter what he said....its no wonder this forum is going downhill when posters get sh*te like this....everybody makes mistakes, and not everyone is a technician.

I would think a 7990 at stock settings was fast enough just to keep at stock,at least for a while.

Did not overclock my 7850 for nearly 2 months after i bought it,enjoyed the performance it offered at stock and after a while i found the most stable overclock it can do being 1050/1450.

I used to hate amd drivers with a passion myself but i give amd credit lately for picking up the slack,rocking 13.1 and as stable as ever with zero issues anywhere as also with overclocking....Op spent to much money on this card to get this frustrated with something most likely not driver related.

The point here is that there's no need to jump to conclusions and blame something as cliché as AMD drivers suck. It's difficult to want to help someone that barely wants to help themself with fundamental troubleshooting. This is why the OP warrants such rash responses, not because they're human like everyone else.

Like said before by others, proper troubleshooting and stability testing is needed. Not ranting and raving about how AMD drivers are to blame for a faulty system.

Solmiester is correct, we are here to help, not to ridicule, and should remain civil at all times.

OP looks like you have solved the problem, at least for the most part. Good luck with the new OC's when you get the new PSU.

Yes I found the issue. I maxed out the 12 v rail with my previously stable 5.0 ghz oc and adding the 7990 causing the driver to crash when it was demanding a high power load. Thus the psu was the root not giving enough power to all components to appropriately operate. This confirmed by daisy chaining my ax 750 and tx 850 together running the 7990. On its own psu and the rest on the other an I was able to do 5.2 ghz and a 1150/1600 oc and run for 24 hours like this running benchmarks and games with 0 driver crashes. So the doves answer is I need a ax 1200 or seasonic x 1250

This noted as a 560ti needs a lot!!!!!! Less power than a 7990 do the drivers crashed due to lack of power. So now all is working fine at 4.0 and stock 7990 settings with the DVD drive in hooked while I save for the ax 1200

so just to summarize, its not amd drivers that destabilized your OC, but a lack of power? your thread title had me concerned.

We already tried to get him to change the thread title before but it ended up with an equally poor thread title. Who knows what we will get this time around.
