I just wanted to let everyone know that Scott and I worked together all last week (using GoToAssist) and we fixed both of our Titan Zs.
Scott had accidently flashed one GK110 with a Titan (2013) bios. I had bought a ‘for parts/not working’ Titan Z with driver issues off of eBay for $599.99 with free shipping. I must note that he had a 4 Dell OEM Titan Zs and the one I bought was also a Dell OEM part. The eBay seller claimed it was an EVGA part but when I got the Z I noticed it had a Dell part number. Also, GPU-Z showed both GK110s had an EVGA vBios meaning it most likely had a bad bios flash. Before contacting Scott, I had used all Titan Z bios on TechPowerUp’s Video Bios Collection with no luck mainly (IMO) because the vbios on TPU are either just for GPU1 or GPU2 and are from different subvenders.
At first we used the latest versions of Nvflash (Windows v5.227.0.1 and DOS v5.163) and GPU-Z v0.8.6 to save bios from one of Scott’s working Titan Zs, but none of these bios seemed to work despite flashing with either version of Nvflash. We did not have Nvidia drivers installed when we were trying to save bios and flash. Also, all of these tries were done while using windows 8.1 64-bit (Scott) and windows 10 64-bit (me).
Finally, Scott suggested we both install/use Windows 7 64-bit. We then used the earliest version of Nvflash Windows (v5.164) to come out right after the Titan Z. The newest version of windows nvflash, to my knowledge, doesn’t allow the old overrides of -4 and -5 (important for flashing Scott’s Titan Z) and older versions didn’t work with the Titan Z. Using just Nvflash v5.164 with administrative privileges, we made a bios copy of the PLX chip and both GK110s from one of Scott’s working Titan Zs. We then flashed Scott’s bad GK110 with the good bios copy and it worked! I then flashed the PLX chip (the bad flash on my card may have been from flashing the PLX chip) and both GK110s of my Titan Z. I was careful to flash GPU1 with the correct bios (80.80.5A.00.01) as well as GPU2 (80.80.5A.00.02).
Needless to say, my Titan Z is now working as well! I’ve tested it by looping Unigine Heaven 4.0 and playing Fallout 4, Assassin’s Creed Unity, GTA V, and the Witcher 3 over HDMI and DisplayPort on a 4k monitor. I’ve also tested it on another computer with Windows 10 Pro 64-bit with no problems.
Long story short, I have working vbios copies for a Titan Z as well as the PLX chip (it is an 8747h). Please, if anyone needs copies of the vbios just shoot me a PM and I’ll email them to you ASAP. I know I could upload the vbios to TPU but, as stated earlier, none of those vbios copied using GPU-Z v0.8.6 seemed to work and I’m not sure how to upload to TPU without using GPU-Z. Each rom is labeled accordingly; GPU1 = titan1.rom (80.80.5A.00.01), GPU2 = titan2.rom (80.80.5A.00.02), and PLX = plx.rom.
