View Full Version : iMac G5 revB GFX Chipset speed.

Just ran ATIcellerator II on my new iMac, looks like the chip runs at 324mhz and memory at 202.5 mhz. Rather disappointed in the memory speed, but we'll see what we can do later :)

Also, FYI, in order to get 128bit memory, you have to have 2 matched pairs, not only in size, but also in latency. i.e. 2x512MB dimm with 333 timing or something.
