I have one rig with 2 5830s and just ordered my second with 4 of them... Smiley 

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. 

The two I have are sapphires, the ones from newegg...

with new difficulty i am running my sapphire 5830 at 950/400 with 73C right now... seems stable and gives 290MHashs... don't want to go higher 

I must be going something wrong.  Every time I use Afterburner or trixx to move the Memory clock at all (anything below its default) the whole system freezes and I have to hard reset.  Cry
