I've got one of those "fun" Rev A (ROM and mobo) beige G3s that happens to recognize 256MB low density PC133 DIMMs. I know that the beige G3 (of any motherboard or ROM revision) cannot recognize high density RAM chips... but there are a variety of low density 512MB chips out now that weren't around last year or the year before.
I've read at least one other poster on another forum claim that the 768MB max limit is something in the ROM and that even if one installed (supposedly recognizable - the poster was reluctant to recognize the existence of low density 512MB DIMMs) 3x 512MB DIMMs, the system would only address 768MB of it. Is that correct?
Or is it as xlr8yourmac.com explains it: The memory controller can only address chips as dense as 128Mbit, and there is some 16 chip limit to the number of 128Mbit chips per DIMM it can address... And since the beige G3 only has 3 slots, 768MB is the max RAM...
An actual hardware ROM block seems a little strange since the MPC/MPX (as in the B&W and Yikes G4) memory controller certainly ought to be able to address far more than 768MB of RAM.
Any thoughts?
