Re: GUIDE: Reflow GPU fix - 56K WARNING!!!

It looks like GPU Medics don't want to talk. I've had a dam good search on the net but found nothing. Any ideas??
Its a T43p type 2668-AY5 and the board number is 39T0147. I just need to know the number of PCB layers. I'm surprised I can't find it!

Please help guys
