Nvidia GTX Titan - modified VBIOS for more control and better overclocking

Recommended Posts

I ran into an issue.

I tried the bios on page 1. Everything was fine. I tried playing WoT. It still wasn't running at the desired clock rate. I messed with power level 2 to change the clock rate and my computer froze. I keep getting bsod's. I've tried reflashing the card back to the stock vbios with a usb dos boot and I still get bsod's booting normal or safe mode.

Any advice?

Little update. I had to use the win7 disk to recover. Weird... Back to finding out why WoT won't stay at the desired GPU Clock?

Previously on stock bios the card would reach 1045mhz, but not stay there long and throttle way down. It was throttling down on the rev0.4.1 as well.

Alright.. downloaded the OC edition v02 (SC version). It's at 928Mhz. It stays there fairly well, but still throttles down. I'm unclear as to why?

It's going down to 758Mhz 55C and even down to 640Mhz with a temp of 53C and fan at 75%. The fan control is the only thing I have changed.

Any thoughts? This is driving me crazy.

Making some progress.....

According to GPU-Z the "PerfCap Reason" is due to "Limited by GPU Utilization". My GPU is in the 46-58% range.

How can this be fixed?

Yes, but do monitor temperatures and don't run with a heavy overclock 24/7. At maximum load with a factory-attainable overclock, the reference cooler already hovers around 65-70C. Most people have to go lower since GPU Boost 2.0 is enabled and causes instability. Without that, you can go higher, and I figure temperatures will hit about 75C tops. This is all assuming your room's around 20C, though.

I'd be able to give you more accurate numbers if I had a vbios for a TItan Black. (Hey, @svl7, read http://forum.techinferno.com/nvidia-video-cards/3454-nvidia-gtx-titan-modified-vbios-more-control-better-overclocking-46.html#post95654 for my adventures on that!)

Does anyone have a guide on overclocking the gtx 880m? And if so may i please have a link? Also, does this modded vbios fix the whole throttling issue with the card, or does it just allow better overclocking and whatnot? (And overall greater stability and eprformance?)

Hello there,

two questions:

Does this OC v4 Bios affect double precision clocks?

Is v4 generally preferable over v3? To me undervolting is important, so I want to make sure that I choose the correct bios and that double precision will still work.

Will this bios file / flash work  for the GTX Titan Z card?   I have tried to flash it without success with a different bios file. I also have had issues reverting back to the oem bios that I thought I saved........../sigh

 

If not, do you know anyone or where I might get one that works or where I can get a OEM version to reflash it back to the original bios?  

 

Any help will be greatly appreciated............

 

Thanks,

Both answers - the links were indeed broken but I've repaired them. You won't have access to them until your account reaches Promoted status as per our rules here: https://www.techinferno.com/index.php?/announcement/4-user-account-promotions-please-read/  However in the next few days we will be taking legacy files like the ones in this thread and moving them to our download section where they will be available to anyone.

Hi folk! I was very happie with my titan bios until I bought a new 4k monitor and I'm having too many issues,  I did a few custom bios with KeplerBiosTweaker but are not really great, any user with 4k monitor could give me a  feedback about  80.10.3E.00.01_-_GTX_Titan_'OC_edition'_rev04.1_Downsampling_Version?

Many thanks in advance  ; )
