MSI 660GTX TF wacky bios flash

post #1 of 5
Thread Starter 
To start off with I've been searching for 2 days for the right problem an have not found a scenario that fits so if someone has asked this question before please point me to the post and i will read. But here's my problem.
I was trying to unlock my bios with this guide here http://www.overclock.net/t/1330897/official-gtx-660-non-ti-owners-club . But when I tried retrived the bios from GPU-z it said it could not unlock so I went to the MSI site and downloaded the bios then unlocked it and flashed my cards(yes cards i flashed them while they was in 2-way SLI) in windows 7 64-bit Ultimate. Everything was fine until i rebooted, the cards were displaying messed up video(i have pics if u need to see). So i went to flash the stock bios from the MSI site with no avail the video was still messed up. So my next step I tried to flash the bios I pulled off the card with GPU-z and it says i need a newer version of nvflash. So I decided to follow this post and try this way http://www.overclock.net/t/593427/how-to-unbrick-your-bricked-graphics-card-fix-a-failed-bios-flash . Needless to say that did not fix my video problem either. The cards are not bricked(I don't think) and can be booted with the usb and safe mode in windows i just can't get the video anomalies fixed. Any help is appreciated.

As a fail safe...................

1. Make sure you are using the 100% correct VBIOS for your cards. If they are different cards (brand, model etc.) make sure you have the correct BIOS for both.

2. Remove one card and reflash BIOS on it.

3. Swap cards and reflash BIOS on it.

4. Boot into SAFE mode Windows

5. Clean uninstall of existing video drivers using Windows uninstaller + clean up tool like Driversweeper or Display Driver Uninstaller

6. Reboot when finished and install video drivers

As a note I always uninstall and then reinstall the video driver when I do a video card BIOS flash.

I have tried to flash 1 card and still the same result im not sure if i have the right bios or not because i can not find the exact match to the card i have. this is the card i have http://www.newegg.com/Product/Product.aspx?Item=N82E16814127756 and this is the bios i used http://us.msi.com/product/vga/N660Ti_PE_2GD5OC.html#/?div=BIOS. Here is some pics of what is going on with the video. I am also flashing with a usb stick with 98 boot files and nvflash.

Finally after much searching I was able to find the correct bios file for my cards and was able to flash them through NVFLASH usb stick. I believe the problem I had the first time is I was using a older version of NVFLASH. But any way since this bios is working on my cards can i unlock it without any problems and if so how I might do that with out ending up with the same results as last time.

Hard to say Waj.

All you can do is try. But at least now you have confirmed that you can successfully go back if there is a problem.
