Inno3D GeForce 8500 GT and BIOS flash to better performance? - 2008/09/03 20:16Hey everyone, I got an Inno3D GeForce 8500 GT iChiLL card with 512MB Memory. Can someone point me in the right direction on which BIOS file to use as I can't find one or I am just blind. I would love to up this cards performance. Thank you kindly.

Re:Inno3D GeForce 8500 GT and BIOS flash to better performance? - 2008/09/03 21:19Well if you are just looking to bump your clock speeds up a bit, it is best to find the highest most stable speeds your card will run at with RivaTuner, ATITool, etc. Then backup your original BIOS via NiBiTor or GPU-Z, and post it here or in the proper BIOS thread, open the BIOS and edit those clocks with NiBiTor, then with nvFlash on a bootable DOS media reflash with the new saved BIOS...

Re:Inno3D GeForce 8500 GT and BIOS flash to better performance? - 2008/09/03 22:36Okay, got the flash program and NiBiTor. Now I have found out the max my core and ram can get to. Do I put the max values in and save that file and flash or do I put in what I want to get out? Another thing once I have set the max values that is stable in NiBiTor and flash those values will become my default settings but can I then use RivaTuner to push it more? My stock clocks for my core and memory is 600/1000MHz. The max stable values I have been able to get via RivaTuner is 700/1100MHz.

Re:Inno3D GeForce 8500 GT and BIOS flash to better performance? - 2008/09/03 22:43Probably wise to set 10MHz or 20MHz from max, as reserve for warmer days, some dust build-up over time. And you do, still use overclock utilities to fine tune later, especially really cool days can play some more. And yup save and reflash with the new BIOS, good to go with new defaults. Just make sure to backup and save your original as, always things can go wrong...

Re:Inno3D GeForce 8500 GT and BIOS flash to better performance? - 2008/09/04 12:46Okay, I think I hit a problem that amazes me. I first tried to save my original BIOS by use of a floppy now when I boot up into the disk I run nvFlash to save the BIOS but it says error no NVIDIA display adapters found. Lol I didn't even get to flash yet. Any ideas on this? My PC does boot up with the NVIDIA BIOS screen before posting to BIOS. Using NiBiTor I can read my BIOS. Am I doing something daft?

Re:Inno3D GeForce 8500 GT and BIOS flash to better performance? - 2008/09/04 13:21I always name it specific, for the card I'm workin on. If you are in proper DOS with nvFlash on the bootable floppy this should work. Same when reflashing the new BIOS, keep it simple. No not daft, just have to get commands and the few steps right on. I found, in no time you be backing up, flashing like a mad man...
NiBiTor can backup, just have to read into NiBiTor or to file, then save, edit saved BIOS and save an rename then flash this new BIOS. With the "-4" option you will force the flash and you should be set. You can try the different commands.

Re:Inno3D GeForce 8500 GT and BIOS flash to better performance? - 2008/09/04 16:10Mohaha, I feel like a mad scientist. My lecturer thinks I'm nuts. I gona try your commands when I get home. Another thing my voltage right now is 1.32V and I have read from a dude that got a similar card and pushed his to 1.38V. Now I see the only way to set it is via the voltage table editor. Is this correct because I do not have the box that says expanded voltages well I do have the box but I can't click on it. Any ideas?

Re:Inno3D GeForce 8500 GT and BIOS flash to better performance? - 2008/09/04 16:31If you can't access the voltage table for higher voltage settings, this may be a limitation of your particular GeForce 8500 GT, a different BIOS may help, but somehow I think your card is voltage hardwired at that voltage and a voltage modification may be only option and is hardly worth it. Not gonna get much more from a GeForce 8500 GT anyway... Yes I'm nuts, ask Mavke, welcome to the club.
Well I looked at an XFX GeForce 8500 GT BIOS I submitted recently and no there is no extended voltages in Exact mode. In VID mode there are two extra voltages both unknown, so this may be where the extra voltages exist but only way is to enable each and check with the BIOS then with the card or with voltage tester when card is running, a little trickier. For what it is worth, not gonna get much more for the effort...

Re:Inno3D GeForce 8500 GT and BIOS flash to better performance? - 2008/09/04 17:22Okay dug a little deeper and with the BIOS open in NiBiTor in the tools drop down section there is the voltage table editor option where you can create an Extra mode of 1.38V if this is your desire, and apply to Exact mode save and reflash. As I don't have a card to test this, may or may not give extra voltage. Make sure to backup and have your original unedited BIOS in a safe place. The BIOS I attached is from my XFX GeForce 8500 GT, I don't have access to card to test. Has a VID added of 1.38V, this as an example I recommend you using your own BIOS and modding...

Re:Inno3D GeForce 8500 GT and BIOS flash to better performance? - 2008/09/04 17:26Here is the XFX GeForce 8500 GT BIOS with 1.38V applied needs to be tested. So try highest stable clocks with your BIOS of 1.32V then with the new BIOS of 1.38V and see what gives. Oh, just a reminder to all, BIOS flashing is always risky and there is risk of floppy failure, power outage, etc so flashing is at own risk...
