Adrian's Rojak Pot have thrown up Rev. 2.0 of their flashing your Radeon 9800 Pro To Radeon 9800XT Mod Guide with a new Doing The ASUS Mod page! Here's a snip.
The 256MB ATI Radeon 9800 Pro is probably the least popular ATI graphics card. It is a lot more expensive than the 128MB variant and the extra 128MB of memory proved rather useless. But while you may think that it is a sheer waste of money, it may actually turn out to be a real steal! Why? Because Now, what is interesting is the new batches of 256MB Radeon 9800 Pro graphics cards are actually Radeon 9800XT cards! There is virtually no difference between the two cards, except for the BIOS. The 256MB Radeon 9800 Pro's BIOS restricts the card to its official clock speeds of 380MHz core and 350MHz memory. It also disables the OVERDRIVE and thermal diode features of the 9800XT.
But if you reflash the 256MB Radeon 9800 Pro with a Radeon 9800XT's BIOS, you unlock its hidden features and the card automatically runs at 412MHz core and 365MHz! Just like any other Radeon 9800XT.
