The GPU Power reporting mechanisms have been corrected in our latest drivers and is available for customers in new versions of 3rd party GPU monitoring applications like EVGA’s PrecisionX version 4.2 and latest MSI Afterburner BETA. In addition, we have added even more information about why a particular GPU is limited to a particular clock. This new information is also visualized though the same 3rd party applications. Last but not least, we have introduced a new fan speed algorithm for GK110 class GPUs which eliminates fan speed variations caused by fluctuating GPU temperatures.

I hope this does not mean algorithm change in power reporting and fan speed affects modified BIOS ?

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.

far327, good to see you here.

Interesting enough, my stability issues with Skyrim is gone after I started using this BIOS. I think fixed/constant voltage (and perhaps others things which I may not be aware) helps with stability in Skyrim. I'm going to test for a few more days until I can 100% confirm.

Let us know how things pan out with stability in Skyrim.

Indeed. That what svl7's comments suggest. However, I don't think "it has some tiny changes and is a bit newer" automatically means better.

I maybe mistaken but I thought svl7's BIOS is based on Asus (and EVGA SC BIOS) because his Titan is from Asus.

Also, EVGA SC version of his BIOS probably is based on the Asus BIOS with updated/changed subvendor ID in hexcode and default 3D clock difference (876 vs 928). If this is the case, this means they both are eventually identical.

Thanks for this detailed explanation! Now I know that using neutral nVidia BIOS has no benefits and it's better to choose ASUS branded BIOS.

How did you come to that conclusion ?

It's my understanding that all Titan BIOS are the same except for subvendor ID. (Just like GTX690 was) Some vendors such as Asus and EVGA choose to insert their ID (signature or brand tag however you want to name it) in their BIOS (eg. EVGA (3842) and ASUS (1043) etc) even though they are just the same reference PCB straight from NVIDIA. And there are many other vendors such as Zotac, Gigabyte, Galaxy etc who do not bother to insert their own subvendor ID to reference deign. Hence, subvendor ID = NVIDIA (10DE) remains the same.

Thank you svl7 for making and sharing this BIOS.

I've flashed and done some tests with games today. The BIOS is great. I have more control over my Titans, thanks to the removed GPU Boost 2.0

I purposely let GPU temps go over 80C to see if downclocking kicks in. And your BIOS keeps Titans at rock steady clocks. No throttle, no downclocking whatsoever.

And if GPU usage drops due to less demand on GPUs, it downclocks and this is a good thing.

Overclocking using NVidia Inspector works fine. (Creating overclocking shorcuts for my Titan SLI and putting them in Startup folder also works great.)

Overclocking using EVGA Precision X also works great.

Although I have not tested with MSI AfterBurner, I see a few posts in this thread that overclocking using MSI AfterBurner does not work with your BIOS for some reason. It was my understanding that EVGA Precision X and MSI AfterBurner are essentially the same program made by Unwinder ?

Anyway, thank you svl7, again for the great BIOS. This is the best BIOS for Titan.

Personally, I've experienced microstuttering with GTX580s and GTX690s. But for some reason, I have not experienced microstuttering with Titans, yet.

It's somewhat surprising that performance & stability issues with Nvidia is still not fixed. The latest patch for Tomb Raider still states "stability issues with Nvidia cards are not fixed, yet."

There's no memory temp sensor so its hard to say. Could take a laser temp gun to it I suppose but it still wouldn't really tell me if its running cooler or not.

I see. Well.. at least temp isn't higher with backplate. And it looks nice. Good enough for me. Heh

Nah... 3770K @ 4.5 is awesome. 4.5 is the sweetspot for 3770K in terms of power, heat and performance, IMHO.

Looks great! Any chance of lower temp? (even at least by 1C?)

I've been using Steelseries Sensei for almost a year now. Love it.
