700mhz wall on HD4850 is smashed.

[Shocker003]

I'm using swiftech ram sinks on the chips and the vregs. Also got a 80mm pointed at them:



I'm experiencing a problem. Sometimes my screen will just go black and the system hangs, sometimes it gives me a BSOD of some atidag file.
It's totally random, most of the time during browsing in internet explorer.
this happens with 1.32v on the core doing 820MHz which is totally stable (passes 3dmark, crysis and atitool 10 minutes). any ideas? I get the idea it happens when the card is switching from low 2d to high 3D and the other way round.

Thanks DemonEyez, i have to order new ram cooler. Can´t you lock your card so that it will be in 3d mode, it may stop the crashing or BSOD
Sorry am high on for now we are losing to Spain 1:0 Germany
