Many years ago I purchaced an Amaze HD3650 AGP Brand New on clearance from MSY Clayton (local parts chain shop). Australians will know MSY from their parts.pdf pricelist
I haven't ever used the card in a build, but decided to do a Fast AGP build with a Sempron 2800+ Socket 754.
After the AGP Hotfix drivers were installed, games would run, but crash shortly into the game, with the VPU Recover function detecting an error, including benchmarks like 3dMark2001.
I tried all the many variations of Hotfix drivers, but not could resolve the instibility. Tried disabling Fast Writes, AGP 8X, Calibration Cycle.... Nothing helped
Tried other systems like P4 3.2 etc, all wth the same results. I concluded that the video card was faulty.
I then was looking in the Catalyst drivers, and noteced that the card ID mentioned it was a 1GB model, when this was definately a 512MB version.
I then through about all those recent "Wish" fake flashed cards and the similar chashes they created....... I deceided to flash this card.
Found a Visiontek HD3650 512MB AGP BIOS on techpowerup, and flashed it....
Low and behold, the card now works flawlessly.
The Visiontek was clocked much lower than the Amaze, but Overdrive fixed that.
Who knows how it ended up with a 1GB filename in the ROM from the factory, or if it was just something flaky with the BIOS version, but all good now...
Spent many hours troubleshooting drivers when that wasn't the problem 🤣
