INITIAL POST:

Currently running a Gigabyte Radeon 6850 with the following standard clocks:
2D Mode: GPU Core 100Mhz; Gpu Memory 300Mhz, VDC 0.945V
3D Mode: GPU Core 775Mhz; Gpu Memory 1000Mhz, VDC 0.945V

In 2D Mode experiencing artifacts in certain situations, when I move windows a lot or move mouse over dynamic elements such as windows/browser menu, buttons, etc.
Encountered particularly nasty crash (BSOD) while starting GPU-Z.0.4.9

I'm currently using the latest bios from the manufacturer, previous version had the same issues, I updated it recently because of a common noisy fan problem.
Not encountering any problems in Furmark after 10+ Min of punishment.

Is this a driver issue or are the 2d clocks set too low in the case of a handfull of video cards?
If so could anyone suggest a set of optimal 2D clocks for me to set with RBE?

Thanks in advance.


UPDATE 1 (2 Jan 2011):
Seems my card has a manufacturing defect
I will RMA-it. Using any clocks even in 2D mode will not permanently fix the issue. If at all it seems the card's state seems to be getting worse by the day.

UPDATE 2 (21 Feb 2011)
I've sent my card for a RMA, they found no hardware problem so I'm stuck with it...
Could it be a bios issue?, or the fact that I use the EX38 chipset variation? Maybe a bios feature like CPU EIST or C1E function is to blame? Any advice from someone that encountered a similar situation would be greatly appreciated at this point. :(

UPDATE 3 FIXED(25 Feb 2011)
Well I fixed it, as far as I can tell. I updated my motherboard BIOS from the latest to the latest beta (2009).
Everything works like a charm except... now I cant boot from usb drives using Grub4Dos MBR.:banghead: Oh well.

The problem
:banghead:

I reinstalled 3 times, all fresh installs, all with minimal drivers then slowly building up to pinpoint the problem. Hell the 3rd install was from another DVD used by a neighbor of mine, First two were MSDN untouched iso's . It's highly unlikely this is a software issue since it persisted over multiple installs, and every driver set used from the original driver bulk CD right up to the current Catalyst available.

There must be something I'm missing...
