Default Re: 5900xt with PCI-e bios

One would assume this wouldn't work but given the fact that the PCI-e version just has an AGP to PCI-e bridge chip, I'd assume the architecture would be the same. In my case, the card works but I have a few "weird" issues that I'd like to resolve by flashing to an AGP bios.

Firstly, the card shows temp, which is good. However, no overclocking is possible. I cannot even underclock actually! Anytime I "test" the new settings, it fails. I'm assuming this is because the wrong card is being detected by the driver.

Any of you bios modders out there have any ideas? I've attempted to reflash the bios but am getting some I/O errors when I try to save the old on or flash a new on (more details later when I'm home to copy them down).
Because the PCX5900xt and FX5900xt share the same gpu chip, you should have few problems flashing and using a 5900 agp bios !

Also, lots of nvidia vga cards have coolbits/rivatuner overclocking issues when using many of the newer drivers. Never appears as a problem when using overclocking tools like powerstrip.

And the problem is mainly resolved by enabling the "DisableInternalClockTest" from within rivatuner ----> At the lower left side of the Rivatuner "Power User" tab, select 'open database' and load the Rivatuner.rtd file. Now at the "Overclocking" sub section, you simply Enable the "DisableInternalClockTest" option by double clicking and entering a '1'
