Waiting on a Water cool Heatkiller block or an Aquacomputer block. Have not figured out which one. Was gonna tri fire but honestly with the power consumption it is not worth it. My 290 is faster and uses near 150 watts less than the 6990. Unsure what a used 6990 and block may be worth. Hoping to get 150 plus ship
I sold my 6990 220€+post's with arctic accelero 6990

I still have this card running.

Anyone Had such problem with overclocking ?

When I raise Vcore then the gpu is more unstable. For example 1000mhz@1.25V will artifact like hell while 1000mhz@1.2V is pretty stable (except for the Fallout 3 which I game at 950mhz Core).
Putting the Vcore down to 1.175V will even make the Fallout 3 without artifacts but the computer may freeze.

I'm using AUSUM bios and the card is watercooled.
For voltage adjusting I use Msi afterburner 2.3.1 (newer versions don't really like HD6990).
