hi, have just bought a mobo and it uses rimm rambus rd ram, havent come across this type of memory before, wondering how fast it might be, would it be equivalent to sdram or ddr ram, any advice please , thanks
You'll have some trouble getting RD RAM now. Crucial.com says that it isn't making it due to lack of demand. It was something that was started when the P4 came out, but everyone uses DDR or DDR2 now.
To answer your question; from what I know about Rambus, it was considered very fast at the time, with a high bus speed, but with DDR2 clocking at up to 1ghz now, most motherboard manufacturers would not consider it to be worth the expense.
when you install it needs to be in matched pairs. In my old computer I have 2 x 128 in slots 1 and 2 and 2 x 64 in slots 3 and 4. If you are only installing 2 sticks you need blank pieces in the vacant slots as all slots need to be filled.
