− | For the 4D/30 and 4D/35 you need different modules. These memory modules were custom designed by Silicon Graphics and were second sourced by some third party memory manufacturers. These modules were easy to recognize since there was a custom chip on the back side of the module. They were used in both the R3000 based Personal IRISs and the R3000 based Indigos. They were available in capacities of 2, 4 and 8 MBytes. They would typically have a sticker on the backside denoting the size of the module. In the Personal IRIS these modules had to be installed in groups of 4 and there are totally 16 memory slots. | + | For the 4D/30 and 4D/35 you need different modules.

− | As you can see at the model section, there is a difference between the older models (4D/20 and 4D/25) and the newer models (4D/30 and 4D/35) concerning memory. Whereas the old models can use standard 30pin SIM modules with parity, the newer models need proprietary RAM which is identical to the RAM modules used in a R3000 Indigo. | + | As you can see at the model section, there is a difference between the older models (4D/20 and 4D/25) and the newer models (4D/30 and 4D/35) concerning memory.
