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

Recommended Posts

This once more proofs that boost will not give you the best performance :)

The evga bios is from an evga titan.

Indeed. Default BIOS svl7 used for modification looks like the following.

ASUS (1043) BIOS version = 80.10.2C.00.06 (Date compiled = 2013-02-04)

EVGA (3842) BIOS version = 80.10.2C.00.90 (Date compiled = 2013-02-23)

If anything, EVGA BIOS version seems to be newer.

If I understand correctly... ASUS BIOS is newer in code, EVGA BIOS has the same code as nVidia BIOS but higher default frequency.

No.

From what I've seen, default NVIDIA (10DE) neutral vendor BIOS is version = 80.10.2C.00.02 (Date compiled = 2013-01-23). This is older than both ASUS and EVGA BIOS. However, I very much doubt the difference brings anything to us end users.

Not like the good old days when a newer BIOS could bring higher performance...

Latest Metro Last Light Benchmark...

Res--1920x1080, Quality--Very High, SSAA--on

With OCN's bios --- 72.71 --- metroll01.jpg

With svl7 bios --- 85.03 --- metroll02.jpg --- increased by 16.9%

This benchmark was killing Titan SLI but svl7's BIOS saved my day.

Thanks for the feedback @vhco We'd also like more feedback from the rest of you: any issues you find, how it compares to other vbios you've tried etc. If you like this vbios, feel free to donate to svl7 or subscribe to TI Elite. Also, spread the word about T|I, we welcome all newcomers here.

I find it interesting that your minimum framerate did not improve with the BIOS change, but max framerate did. You really are noticing a smoothness improvement though?

There's a definite smoothness improvement with stable clocks. I can tell in bf3 right away.

New to the forum, and new owner of the EVGA TITAN not the OC version, what is the best bios for my card?

Either one will work fine.

@svl7 the only vBIOS with UEFI enabled is the one on the Titan EVGA the one I have my question is if modding the vBIOS doesn't disable UEFI compatibility? because on my asus z77 board with W8 UEFI when I disable CSM for fast boot I can't make it to windows but I think the video card is working on UEFI mode because when booting is on full resolution

I may need to reinstall W8 with CSM disabled

All Titan vbios are uefi capable, and I didn't touch the uefi part, so it should work fine unless nvidia messed up.

I just flashed to the SC bios... decided to settle at a core offset of +60 and mem offset of +100. Power adjusted 110% in MSI Afterburner.

Many thanks svl7!!!

You won't need to touch the power target slider with that vbios, it won't make a difference, the default value is already enough. ;)

OK, I did Metro Last Light Benchmark again with latest nVidia driver 320.14...

Res--1920x1080, Quality--Very High

With OCN's bios --- 110.64 --- metroll32014ocn01.jpg

With svl7 bios --- 119.98 --- metroll32014ti01.jpg

--- increased by 8.5%

Want to thank the maker of the TITAN Vbios it worked great had no issue was hitting over 1200MHZ, sent some money for beer.

I used opt33 and RR09SS. Naennon's bios will lock up my Titan. So this time I used RR09SS.

Hi svl7, do you think there is a difference between your vanilla custom vbios and the "SC" version?

Cos I'm only able to reach a maximum of 988MHz on my core clock and 1552MHz for my mem clock on stock voltages which people are telling me that these values are too low.

Then raise the voltage using nvidia inspector and you'll be able to clock much higher.

I don't comfortable raising the voltages as I'm on air and I'm living in a pretty hot area. Are my settings an average overclock?

Dude I live in Arizona (desert) and I have raised voltages. I think you'll be fine, try 1.175v and 1080 mhz.
