I have one rig with 2 5830s and just ordered my second with 4 of them... 
The two I have were unstable anytime I tried to clock above 970, or memory below its normal 1000... what gives... how are you guys able to OC them so high and they last for days. (shrug)

different brands overclock differently. Almost everyone posting the 300+ scores is using the Sapphire card that newegg had on sale for $99-109.
