Performance went up surprisingly, however I can easily see some issues during benchmark. Not artifacts or glitching but microstutter and high fps to low fps to high to low again. Definitely the effects of our performance limiting. Up until this point its been liquid smooth.

Yep thats right, performance tanked. Going to run it one more time, then try again with a little more voltage. Looks like this is past the PDL limit, but lets make sure. Only two of the tests dropped in performance, and to be honest, I would have expected all 4 Graphic tests to drop, not just the first two.

Okay, exact same run as before, the score is better, so it could be "score variation", but here we have less GPU usage that is actually a bit more stable. The first two tests are stable, the second two are better than 720 MHz. The overall performance still dropped, lower than 720 MHz, so now what I will do is re-do the test with another voltage increase to see maybe its just needing moar power.

If it gets worse, than definitely passed the Power Draw Limit... welcome to 590 overclocking

I appreciate it, they are not the best scores in the universe I am aware, but they are fairly decent, since essentially anyone can get these scores, not extreme overclockers or those on LN2. The worst case scenario is a water cooling loop (which everyone should have.)

I was really hoping my 590 Overclocking thread would have helped educate / help users submit some decent scores both on OCN and HWBot They are really intimidating cards to overclock, no doubt about it, both by press and by how they behave. Instead of a driver crash, a program/benchmark crash, or even a BSOD, the most common behavior is a hard freeze, or a hard power off. Its enough to weed out most people.

Also, if you look at my last few submissions, you can see the scores have already gone down. There is no benefit to overclocking after a certain point (only in some applications) due to the power draw limitation. You are probably more familiar with the concept of what happens when a 580 runs Furmark. Its that "issue" we have, just on almost every game and application.

Additional voltage tanked my score further. So really between 700~730 is crossing our threshold in 3DMark11, and going any further is not going to happen, at least performance wise. Notice that some of sub-scores are worse than stock? Thats okay, our "safety" mode takes us to 540 MHz, not whatever our BIOS has for stock. Awesome huh? Apparently even stock is not safe. I would really like to chastise whoever's idea this was.

Change in Uncore frequency, an extra 400 MHz, seems to have leveled out some of the GPU usage. You can tell by my imagery.... I really didn't want to go this route for points, I wanted in on the GPUs, but I rationalized it a little as it was minutely bottlenecking the Quad SLi. I know that 4.4GHz is more than enough to un-bottleneck the cards (by experience), but there is still a little overhead from the system communication. Seeing that it does indeed benefit from this. I will keep it in.

While in BIOS, I raised the PCI-E up another 10 MHz to see if there was any change... in actuality, my GPU scores went down. I may consider returning this back to 110 MHz.

This is my all time best
