Hi! Great work. I have the same "problem" with my Ati 4850m that I have in my msi gt725. I can overclock to stable 530mhz and if i try higher i get random freeze for few seconds not bsod but it will freeze and after that will work ok. I think the reason for this is because we have low gpu voltage only 1.05v. Desktop cards have like 1.10v. What I did was extract my vbios using gpu-z and change gpu voltage with RBE. I tried bumping voltage to 1.06v or 1.07v and reflash my modded vbios. It flashed with success but I had to reinstall my ati drivers for changes to work. Unfortunately after that when I tried to use any 3d game i got random artefacts on the screen ( black random lines ). So I went back to my stock vbios. Maybe try rising gpu voltage in your vbios? In my case this did not work but maybe it will work with yours gpu?
