i am pretty sure i have a rev B iMac 233 as the video chip has an ATI 3D Rage Pro Turbo PCI stamp on it. this being the case i can have 2x256 144-pin PC66 SO-DIMMs correct? currently, i have the logic board torn down and the memory daughterboard has a 32MB DIMM (SEC KMM466S424BT-F0) on the underside; apparently someone has done a memory upgrade at some point as the top easily-accesible slot has a micron (i believe) 128MB SODIMM in it. now for the dumb-ass question: since this (i am pretty-sure rev B) model has a max capacity of 512MB then i will need two 256MB SODIMMs, can i purchase two of the same DIMMs?

also, apparently the video memory has been upgraded with a 4MB VRAM chip (KMM965G512BQN-G0) - this means the video memory is maxxed, correct?

thanx

wait, i just took a closer look at the logic board, by apple's logo and copyright there is a model #820-0980-A, does this mean it is a rev A?
