Hello everyone, I wanted to ask for help here because I don't know what to do anymore. I have these two cards, which were modified in the bios, and corrupted everything. Both cards are 64mb 128 bits. I found some bios out there on these old sites or in the archive, but some bios work, some have a black screen, but they usually cause a lot of problems. I tried to edit these bios with the bios editor, and I even managed to leave the original clocks, but both of them can never get to 64mb. They read 32mb, sometimes 16mb, but they can never read 64mb. Sometimes 128bits doesn't even work, it only reads 64bits. I tried to use HXD to edit it too, and unfortunately I couldn't. Does anyone have the bios for these two cards or could make a dump? I have already reviewed the entire board, the chips are well soldered, both work and recognize the drivers, I can play normally with them, however the amount of memory never reaches 64MB
the first model is an
ASUS V9180 VIDEO SUITE 64MB (geforce 4 MX440)
and the second is a
CHAINTHECH 64MB (geforce 2 mx400)

So why did you flash these ROMs in the first place?

I bought them in a batch of used AGP cards; one came with the MX460 BIOS and the other with the 16 MB MX400 BIOS.
The original BIOSes are gone. In fact, I'm trying to recover the cards to use in my old PC with Windows 98, but if there's no solution, they'll go back to the trash.
The previous owner probably tried to overwrite the BIOS and screwed it up. If you search on Google, several old forums have people trying to make a BIOS mod on the MX440 to the MX460.
Unfortunately, I was unlucky enough to find a card that passed through these people's hands hahaha

I have asus V9180SE 64MB 64b laying around. That's obviously a different card with different configuration so likely would not work, but i can dump it if it is going to be of any use...

you asus card has bga memory chips, mx460 cards were with bga ddr chips, that's why it uses mx460 bios.

bios from tsop cards is not compatible with bga cards

I tested several of them, some work but do not recognize 128 bits or 64 MB, others work but only read 32 MB of 128 bits or even only read 16 MB, and in the last case the card has no image or is full of artifacts on the screen 😒

Do you think Asus could have used the modified mx460 bios to work on the mx440?

if the card does not detect full amount of memory then most likely you have to reflow/reball memory ic.
it is common issue with bga cards, especially from "the pile of .." -)

also look for damaged resistors on the back side.
check every resistor, it is something like 4x560 4x680 4x750 ohms resistor around memory chips
