GTX 780 SC problem

havok2191 · June 13, 2013

Hey guys,

I'm testing my 2x 780s individually and I noticed a very annoying problem with just one of them. I am testing on my home rig (see below). I noticed that when I run this one specific card I bought (I have 2 SCs, and friends have 1 ACX SC and 1 normal SC) would keep BSODing when I was using my OC'd CPU clocks. All the other cards were perfectly (booting into OS/running benches) fine except this one.

I am running a slightly overclocked CPU at 4.2Ghz with 1.15V to the VCore and everything else auto. I did multiple Prime95 runs (each 10hrs) and AIDA64 runs (10hrs as well) to make sure the system is stable (using a GTX 680 SC and one of my other 780 that was booting properly).

I reverted my BIOS to stock settings and only then this card I was having problems with would boot into Windows properly. I ran Unigine Heaven and Furmark and saw 98-100% utilization with stock clocks but its a waste of money to buy a K and run stock.

I even ran higher voltage to VCCIN, VCore, DRAM Voltage, lowered Ring multiplier, etc [Did this all moving 1 variable at a time] with no results

I'm using the latest 320.18 drivers (installed them properly using manicVVV's way on eVGA forums) and I extracted this BIOS: GK110 - 80.10.37.00.80 (P2083-0020).rom from using GPU-Z. Any idea what the problem with this is?
