RIMMs (Rambus Inline Memory Modules) are typically available in various speeds, commonly classified as 800 MHz, 1066 MHz, and 1333 MHz. These speeds correspond to different data transfer rates, with higher frequencies allowing for increased bandwidth and improved performance in compatible systems. It's important to check compatibility with the motherboard and processor to ensure optimal functioning.
RIMMs operate at speeds of 600 MHZ (PC600) or 800 MHz (PC800). All installed RIMMs must operate at the same speed, and have the same ECC or non-ECC rating. The operating speed is different than the data path size. RIMMs are avilable in 16- or 32-bit data path.

You replace C- Rimms with Rimms.
because they're bad
RIMMs are traditionally faster and more expensive
You replace C- Rimms with Rimms
For RIMM modules, install the RIMMs beginning with bank 0 then 1 and so on.
