Normally I wouldn't bother messing with vga bios, but I have intermittent flicker problem with my fx5200 ultra, that I wrote in this thread
. It could be low quality components, or improper bios setting by the manufacturer. So I'm trying to solve it, in case it's the later.
Thank you again.
you can only find the voltage table when you know what volts you are looking for, by first measuring it on a card !
From my 5900 card I knew I was looking for 2D volts of 1.2, throttling volts of 1.3 and 3D volts of 1.4 ! Then it was just a matter of looking for a table with these volts, obviously allowing for volts being binary number ! If, for arguments sake, we assume your cards GPU volts in 2D is 1.3v and 3D is 1.4v then you are looking for a table which shows stepping options like in my guide with options, and 82 (for 1.3v), and 8C (for 1.4v), where these are just the hex representation of volts, as I show in the guide ! But that is the easy part, as finding important data in a bios is not usually that straightforward. Finding a lot of it is actually based on hunches determined by relationships to other known data locations ! If it was easy, then everybody would be modding every bios that ever existed !
so if you are not confident with finding and changing the right data, or accepting the consequencies of changing the wrong data, then I would leave it alone, and wait for someone else to eventually find the info you want ???
Obviously if we lived in an ideal world, then the easiest way to get the info would be to get your hands on the original bios software data that Nvidia gives to the OEM's. But thats unlikely to ever happen unless someone from Nvidia is personally known ??
and your flickering problem is an interesting one, and from what you listed in the post, you seem to have changed or checked just about everything possible ?? You don't however indicate if you checked anything monitor related ???
After every driver install, did you set OS refresh rates for given resolutions using something like RefreshForce, which is best program for winXP. All refresh rates must be within spec of monitor, regardless if running desktop or game !!
did you also always install your monitor with manufacturers own driver AND NOT either of the OS "default" or "plug and play" drivers ?
You did try with Vsync ON, but that only works as long as OS set refresh rates are meaningful to monitor ?
also, did you ever try another monitor, just in case, because of some fault condition, certain specific circumstancies simply cause its display to flicker ??
