RDRAM : ECC and non-ECC

[juanca]

I want to buy additionar RAM for my PC, which uses RDRAM (Rambus DRAM). I have seen it listed at different prices, being non-ECC RDRAM significantly less expensive. The RAM on my computer is ECC. One question is whether ECC and non-ECC RDRAM will work together. The second question is whether I will sacrifice a lot of performance by buying the less expensive memory.

Thanks for reading

Ecc ram means its parity. Non ecc is non parity. Some mainboards will run ecc even if they were generally designed to use non parity, but I don't think that works the other way around. I don't believe a mainboard that was designed to use ecc ram will work with non parity...it used to not. I had a 486 that was like that. It took parity ram, and would not run with non parity. At that time, (486 days) I was informed that a board that worked with non parity would also work with parity, but not the other way. So, find out what your board was designed to run, and go from there.
