Crysis 3, BF3, Tomb Raider etc.. i can play for hours same as Heaven and Valley.

So far, FC3 is the one that required the lowest clocks for me.

Since it looks like Nvidia is not going to actually do anything about the throttling but instead just have the next drivers report higher TDP's so that they are then technically "within spec" I may have to use these modded bios's after all...

Below are some bios that I made really quick. I tested half of them. Named in this order, Base Clock, Boost Clock, and Fixed Voltage (3D). Note that it does downclock when not in 3d. These can be more for gaming and not wanting to run at max. Some might need the higher volts for the same clocks so I made several. The fan can go up to 100%, if you are deaf. I like to keep my fan at 1:1 and stays in the low 70c range. One thing too I would like to mention is you can use the 875_1045_1150v and still use the Voltage & Tweaks option to raise the volts even higher than 1.150v. Just doing that will most likely raise your core mhz a notch or two, it did for me.

875_1045_1150v.doc 229k .doc file

Flash_Titan.zip 321k .zip file

STEPS:
1. If you have MSI AfterBurner or EVGA Precision, open this up and click DEFAULT first before proceeding. Each time you Flash, go back to default if this program opens at startup.
2. Unzip Flash_Titan folder
3. Copy the bios to the Flash_Titan folder and rename the bios you want, from .doc to .rom
4. Make a copy of your Stock bios, download and open the program called GPU-Z from Techpowerup
5. Hold the Shift Key and Right Click the unzipped (Extracted) Flash_Titan Folder. Select "Open command window here". Note: This folder should have your 3 nvflash files, Stock bios, and any custom bios you want to flash too. Remember the bios above need to have .rom in place of .doc
6. Flash the card with the following two commands:
nvflash --protectionoff
nvflash -4 -5 -6 (name of bios here with .rom, see example below)
nvflash -4 -5 -6 875_1150_1187v.rom

7. Reboot your computer. Driver may need to be reinstalled and the picture might be in like 800x600 or something at first. After the reinstalled the drivers(usually needed the first time you flash to a new bios, after that its not needed unless the vendor field is changed again from a different or original bios) restart.
8. Done!

If you are not comfortable, do not do this. I basically do what many do already and have just put in my own words on how to do this. There is risks, please dont blame me if something goes wrong. It is good to have a second card or an onboard gpu just in case you need to reflash from a bad flash.

I hope this help you all that wanted different volts. Remember you can still use the Voltage and Tweaks option to raise the volts and still use offsets. So, you can start with the low one end bios and find your OC and Stable Volts using Voltage and Tweaks that will let you go up 1.200v from the 1.150.

Notice your Power %, if this starts to hit 100% you might see a tic or two of core dropping (13mhz) or if you hit 79c, this might happen from my experience. You can raise the Power % if you want but really might like to leave it there for gaming until you learn the cards habits. I dont like to run over 80c for hours and the 1150mhz with 1.176v seems great for me with 1:1.

Feel free to point out mistakes in the process or bios. Its late here so I might have missed a step.

Have fun!!! thumb.gif

***Just want to mention that I only really tested these with the default settings and with the fan curve already set. Adding extra voltage or upping the Power Curve might make these bios behave differently. My intention was to have these for a set it and forget it in gaming***

Edit - some reported that on the high boost clock bios I made caused a boost up to nearly 1400 for a second or two would cause a crash. This is because the boost table was moved. I have since deleted some of these bios since I really dont want people to have issues.

Any one notice that Chrome will run at 800's and IE will run at 300's on the core? Even on my stock bios... Strange rolleyes.gif

Thanks SAN_NAS you forgot to add 1136mhz with lets say 1175v. that should cover thumb.gif

I just installed my second titan and flashed both 2 the custom bios. I think 1150 core is the most I can get in sli. Both stayed at 1150 the entire valley run. I think this is a good score.

These bios make my cards run funny in sli. I had to add - and + offsets to each and I was finally able to get them to run even speeds.

Without the custom bios's my cards boosted to about 1071 stock and didn't throttle at all when running heaven. I think that is pretty good for these powerful cards in sli.

Can anyone confirm if 1.21v is safe for gaming for extended periods? Not sure if I should risk it......
