Hi all,
Received delivery of my new R9-280X Toxic yesterday. Since then I have seen severe artefact problems, regardless of what the card seems to be doing. It's happening in a web browser (I use Chrome), WoW, windows itself...while and while not mining. It's driving me fucking nuts.
Some specs:
- Board: Asus P8P67m Pro
- PSU: Corsair non-mod 750W Gold
- Processor: i5-2500K
- RAM: Kingston generic 4GB
- OS: Win 64
- GPU Drivers: Latest
- Overlocking: No
- Overvolting: Yes - the VDDC to 1256 - its default value when I hit "reset" - previously 825, and not (apparently) updating.
I downloaded a couple of utilities:
- Sapphire TRIXX (overclocking)
- GPU Z
- HWInfo 64
It seems it may be a voltage issue with VDDC. I've attempted to rectify it in TRIXX, and I get the following:

So Trixx and HWInfo don't seem to agree. GPUZ says the following: EDIT: Note the difference in min and max VDDC voltage!!! Is this a PSU prob???

So the VDDC seems to be approx 50% too low, and TRIXX is lying to me? Or it's correct and everything else is? Or this is an RMA job? (Please no, there is no stock of these to be gotten!)
I'd really truly appreciate any suggestions or pointers.
Thanks,
Rit.
