Heat rises and you don't have sufficient cooling even if you think you do. I was amazed at how fan placement, not just airflow, makes a big difference.
2000 rpm is too low for the fans. You should have been over 3,000 rpm... define fan speed manually and set it to 100%.. what rpm does GPU-z report?
I must also remind you about Ghetto cool tech™

80mm fans. No larger
or it won't fit on the back plate.

Would it be viable (and safe) to bump the voltage up a little bit? I believe I saw earlier in the thread you had some max voltages at 1312 mV or so. It seems the max voltage you specified in the RC2 BIOS you linked me is 1287 mV. Possible to bump it up a bit to see if my core clock is 100% perfcap-free? Do I just shift all the sliders up by equal amounts, anything else I need to change in the other tabs of BIOS editor?
No.. a voltage increase won't help this issue. It appears that your PSU isn't up for the challenge.
Did you try putting the memory back to stock (+0 Mhz) to see if it helps? Overclocking ram increases power draw so it might "give back" enough power to remove the perfcap.
If not, I could create custom BIOS for you also with reduced power but you may get PWR perfcaps... it might be interesting to see if the perfcaps went away and then we'd know for 100% sure it is lack of power (which it pretty much has to be...IMO ).
