>does the memory make a difference (64, 32)? Yes.
The Radeon 7000 PCI 64 MB DDR cards I've seen have contained slower VRAM chips than the Radeon 7000 PCI 32 MB DDR cards I've seen. There are four *theoretically possible* FLASHing combinations, at least for gen-u-wine ATI Radeon cards: 1) 166.67 MHz graphics processor and 166.67 MHz video RAM, 2) 166.67 MHz graphics processor and 188.33 MHz video RAM, 3) 188.33 MHz graphics processor and 166.67 MHz video RAM, and 4) 188.33 MHz graphics processor and 188.33 MHz video RAM, Of these, there are really only three *technically feasible* combinations, as (3) *must* be handled as (1), above. The old-fashioned way of FLSAHing the ATI Radeon 7000 family (the only real difference between ATI's cards is the presence or absence of certain external connectors and supporting passive components, the remainder of the card is otherwise identical) is to FLASH the card on a PC for the correct combination of GPU and VRAM speeds using a bootstrap ROM image which will ... later ... permit you to FLASH that card with the Mac firmware, using a Mac. The new-fangled way is to directly FLASH the card for the proper combination of GPU and VRAM speeds, simultaneously with FLASHing that card with the Mac firmware, all on a PC. As a general rule, 64 MB cards contain slower VRAM chips than 32 MB cards. The spec of the VRAM chips can be determined by inspection: 1) -6 or -60 means 6.0 nsec (this requires FLASHing as in case (1), above), 2) -5 or -50 means 5.0 nsec (this requires FLASHing as in case (4), above, *assuming* the GPU is also 188.33 MHz [ * ] ), 3) -4 or -40 means 4.0 nsec (this requires FLASHing as in case (4), above, *assuming* the GPU is also 188.33 MHz [ * ] ), and 4) -36 means 3.6 nsec (this requires FLASHing as in case (4), above, *assuming* the GPU is also 188.33 MHz [ * ] ). [ * ] If this doesn't work, it is possible the GPU is 166.67 MHz and not 183.33 MHz, in which case re-FLASH as in (1), above. -- G-List is sponsored by <http://lowendmac.com/> and...
