Today i used RBE1.13 to mod the bios, and flashed it succesfully to gpu=850, mem=1000. The flash worked, and after a reboot GPU-Z reported everything correctly, along with the increased bandwidth (128GB/s).

However, i ran 3dMark06 again, and now the score has dropped to 11k.
Nothing else was changed, the tests were run back-to-back (before and after flashing).

CPU is E8600@4GHz, the rest in my sig.

Anyone got any ideas as to why my score dropped so much???
You could decrease the vRAM clock and if that doesn't work decrease the GPU clock. GDDR5 has a very strong mechanism for correcting errors so it can clock very high but clocked too high it will be slower because packages have to be re-requested () and resend.
