i also got 128mb one out of that deal.
I took out the stock heatsink it came with, and put my monster

D) in it.
memory seem to be maxed out around 580mhz for me if i go higher, i see artifacts and snows.
im fooling around with core, but 300 locks up for me. odd thing is, it locks up in ut2k3 but i can go to desktop

maybe its because im running xp?
ill try 290 now
