The beta drivers did not have OCP on which is why the cards were blowing. This is exactly the same as what happened in the 570 thread. Furthermore, it happened UNDER WATER too. The issue is the huge current through the 4+1 (same as the 590) VRMs. Better cooling like water helps, but does not cure the problem...
Now the official drivers have OCP enabled, but people are already reporting throttling at clocks lower than the 580 (772Mhz). For example AnandTech was at 750 Mhz and they hit the limit...
Unusually—and had we not run this multiple times we would not have believed it—our overclocked GTX 590 underperforms the EVGA GTX 590 with its mild factory overclock. This is one of the reasons we believe we’re blindly triggering OCP, as even if Battleforge were largely memory bandwidth limited our overclock still has a nearly 5% increase in memory bandwidth. The fact that scores are going down means something is amiss.
If you read a few pages back some OCN members are also reporting hitting the wall. As I see it, if you want to go water then go the 6990
-- AMDs power limit can be raised to 540W (20% more than BIOS 1 stock) whereas Nvidia locks their limit at 450W. Plus the noise victory for Nvidia is negated under water.
tl;dr... OCP off (beta drivers)= explosion even under water (see 570 thread) & OCP on (official drivers)= performance wall before 580SLI clocks
EDIT: It seems like they will even blow with the official 267.71 drivers... what is going on here???Edited by JCPUser - 3/24/11 at 5:23pm
