Hope you guys can help out with an issue on my friends PC that I built.

TLDR: Is there any way in the BIOS of this motherboard to increase the PCI voltage? I have seen the option on other boards before so I assume there has to be some way to do it.

Details:

Hey guys. I built a friend a new desktop a little over a month ago. ASRock Fatal1ty 990fx Killer motherboard with an Asus Radeon R9 280X 3GB refurbished graphics card. It was working great up until last week. Whenever he went to play FF XIV he would get really bad artifacting and eventually a striped or black unresponsive screen. It would run fine after a reset, so he was confused.

After taking a look at it it is definitely a GPU issue as it was repeated in my rig, and I run an R9 270x so the drivers are the same, and hisa runs fine with my GPU in it. When running Heaven Benchmark 4.0 it crashes/black/striped screen in about 30-45 sec just before hitting 60*C Great, and of course it's past the 30 day NewEgg return policy on refurb items.

So I read a review stating the card would be much more stable and perform as expected if the voltage is upped to 1.275v or so and power target to 110%. So I installed Asus GPU Tweak/monitor and set the voltage to the suggested numbers, but in HW Monitor after running HB 4.0 for about 10 seconds, it shows a max voltage of 1.200.

Thanks for any help guys! I don't want to have to tell my friend he has a $350 paper weight or can only browse the web with his $1300 PC lol.

Maybe try to use MSI afterburner http://event.msi.com/vga/afterburner/download.htm If it doesn't work out, the problem is from that refurbished card, because that means the card doesn't fix at all during the repairing the defected part.
For me one rule is that don't buy the refurbished PC components, you can buy the open box.
