Tools:

Bootable compact disk and drive

I resolve be via AtiTool in this guide; you are without charge to apply Riva tuner if you similar to it. To see extra information on over clocking Graphics cards see: Guide

Prerequisites:

NVIDIA is newest constant drivers at present 162.18 for 8x00 sequence cards; the BETA drivers do not work with Riva Tuner correctly yet Good GPU cooling.
Identify how to use Riva Tuner Having preceding data of GPU over clocking is recommended

Step 1:

I will not give any details how to create a bootable floppy here. If you don't know how to do it ask some one else for help, find it on the Web, or just don't bother continuing. Form a bootable DOS floppy. Reproduction the files named "cwsdpmi" and "nvflash" to the bootable floppy disk.

Run the program AtiTool. Toward enlarge the RAM speed to the in advanced stable levels. Run "Scan Artifacts" for at least 3 hours. Monitor GPU temperature; make sure the temperatures are within safe limits. If the tool finds artifacts in the 3-hour period, decrease the Core/RAM speeds so that the artifact scan will not show up any during the 3-hour period. Record the Core/RAM speeds. Minimize AtiTool.

Step 2:

Open up GPU-Z. Build up a note of the "Shader" clock. Click on "Save BIOS to file look at screenshot below. Save the file as "ORIGINAL. Bin" to the desktop. Copy this to the bootable floppy disk.

Undo the NiBiTor to make sure File type is set to .bin See screenshot below.
Once the file is opened check the Integrity of the file. Make sure the Integrity indicator is green see screenshot below.

Step 3:

Under "Clock rates" alter the ideals to those of that you obtain with AtiTool. Go through the "Shader" clock value you obtained from GPU-Z. Look at screen shot below. Due to differences in manufacturers and models not all options will be available to all users, you can also change other things such as fan speed, etc with NiBiTor, but I will not go in to those details here.

Save the new BIOS file Save the BIOS as "MOD.rom". Make sure it is a .room file to the desktop. Copy this file to the bootable floppy. Reboot the computer and boot from the floppy.

Step 4:

Once you are booted in to DOS. Type in "nvflash protect off" without quotes. once this is done type in "nvflash MOD.rom" This is the last chance to back out! Incorrect flashing will kill your card. Do NOT Reboot PC at any time during the flashing process. After that stays waiting you get the effectively flash massage. Once you get this message take the floppy disk out and reboot the PC.

Well done! If you have completed it this far you have effectively flashed your original BIOS. To twice make sure release up the GPUZ and observe the stock speed. It should be the same as the values you entered. Run a "Artifact Scan" from AtiTool just to be sure every thing is OK.

ATI BIOS Modding and Flashing Guide

This direction of deals through cutting of and flashing the VGA BIOS on ATI video cards. This guide does not incorporate how to find your card's max stable over clock. Go to cnumartyr's over clocking guide for that. If you have not made sure that your card is stable at the clocks you want to set then stop reading and go and do that! Setting unstable clocks in the VGA BIOS may cause your card to fail to output a signal and force you to do a "blind flash," which is not allotted for fun.

The flash system applies to all ATI video cards. The editing section applies to all ATI video cards except hard disk2 and hard disk3 cards as the software for editing the cards described in this article does not yet work with these cards. These cards will be added later as there are programs obtainable that hold just these cards.

Why would you wish for to edit your card's BIOS? A good question. Sick of having a million programs start up when loading windows and hogging all your resources? Well this will do away with the requirement for the programs that control your cards clock speeds etc, although you will need them to find stable clocks first. Also if you aren't running windows, this is the only way to over clock your card.

Important notes before you start:

If in attendance of there is an error for the period of the flash and the program did mark to the BIOS, Reflash the unique BIOS and make sure the new one is not dishonored. This will save you the hassles of a blind flash from dishonored BIOS. If the program gives an error, but no write occurred it should say if there was no write, it is safe to reboot.

If you flash BIOS by means of a dissimilar tool ID, you MUST reinstall your drivers. If you don't, you may knowledge of image treachery or worse. Keep in mind; as far as windows is concerned you have a different car in there.

Initial obsession you need to do before you are able to get stuck into editing your BIOS is to actually save it as an editable file. Both ATITool and RaBiT can do this.

Accept everyplace you want the file to go desktop is good and easy to find and name it impressive akin to unique. Bin or default. Bin or something like that so you know it’s your default BIOS file.

Editing your BIOS file:

Here’s where you get your hand unclean. Release the BIOS file in RaBiT by going Open. Verify that the program has correctly read your card's chip model in the Device tab.

For the after that few section on clock and memory settings, it is not recommended to enable the "Real-time" checkbox, as any changes you make will be automatically set straight away. I am unsure if this alters the BIOS in real-time or if it is similar to over clocking with ATITool and ATT, so I don't use it, but may in the future. If somebody could clarify this that would be great. If you do try to enable it, you will get a nice caution box so don’t worry if you by accident tick it.

At the present go to the Clocking tab and simply alter the Memory clocks to whatever you want, but make sure that you be acquainted with that’s its steady. Bump the VDDC if you need to, but make sure your card doesn't already run very hot. Note that some cards do not support altering the voltage even though the BIOS have a voltage table and the option to change the voltage is here. This is a hardware level issue and cannot be resolved by software. Several producers are just too lazy to eliminate the voltage table.

Anyhow, on to the Memory tab. Here you can play around with memory timings on the card. This is the easiest way to destroy your card thus requiring a blind flash as well as is NOT suggested for most citizens. You may or may not be capable to modify your memory bus as well as memory size, even though these should by now be fine as well as should not require changing unless you want to make your card slower

Preparation to Flash:

Now a day this is the part that everybody desires to do. Make a bootable floppy and extract ATIFlash files to the disc. Put your original BIOS and your new BIOS files on the disc and write down the names if you need to. Now make a second bootable disc and put the files on that as well, but not the new BIOS file, just the flash program and the original BIOS file. On the second disc create a text file called autoexec.txt as well as set this line into it.

The file extension is usually .room or .bin, it doesn't matter which one you use. Note that this is only for a single video card. If you have more than one video card, you must use a different adapter number. One BIOS can be flashed at a time, so if you want to have two emergencies flash discs, each one will need to specify an unusual adapter number. For a second video card, the code would be the following.

Yet again, the file name can be no matter which. As a replacement for of having two discs, you can simply edit this file in windows after you flash the first card, it's up to you. You might been be able to comprise both lines in one file get the BIOS file name correct for each, but that will without need flash a working card. Now rename the file and you have yourself an urgent situation reflash disc!

Flashing:

Attach your floppy in your work station. Go to the BIOS of your motherboard not your card of course and make sure you have your floppy as your first boot device. Reboot again and DOS will download from the floppy. After that, if you only have one video card, type in, you will use the file name of your new BIOS. If you are using a BIOS from one more card you may get errors, and you may need to add in the further switches to force the program to flash with a dissimilar Device. If you have these problems use the following

That will display lots of information about the adapters and should include the numbers that nvFlash will identify them with (0/1/2...). When you have determined which card is which, you can use the previous code to flash that card, remembering to change -p 0 according to which card you are flashing. Remember that if your flash goes wrong that your autoexec.bat file must include the correct adapter number or it won't fix your problem.

Formerly the flash is absolutely correct, reboot the computer. If you get no signal or amazing doesn't look right, just boot from your reflash card and go back and edit your settings to make sure everything is ok. Open up ATITool and verify that your settings have taken place most should have, but some like voltages and fan settings may not be possible to change.
