Rambus question

[BUTCH1]

Hello all, I dumster-dived a comp. yesterday it's a P4 1.7 gig w/256mb RAM. Cleaned all sockets,
removed dust bunny the size of a throw rug from top of CPU heatsink and powered up..it works
perfect. I want to upgrade it's 256mb memory to 512K to be somewhat usable to give away, it
currently has non-ecc ram in it, if I put in ecc ram will it still work in non-ecc mode?? Thanks in
advance for any help..

Generally it should, but it depends on the motherboard. Some boards do not work with a mix.

If its RDRAM, you are best installing all the same. Depending on the board you can expect memory issues and unstable OS problems.

I do this in two different machines and have had no issues at all. In one machine (intel 815 motherboard gateway p4 1.7) I have a mix of ecc and non-ecc RDRAM. I just turn off ecc in the bios. My other machine which is a dual 2ghz xeon workstation I have mixed 50-50 1.5gb of RDRAM and no issues at all. I did make sure that all were the same timing 800-45 sticks.

Thanks for the help, it's a D850GB chipset, the Manuel states ECC function will only work if
all sticks are ECC but is unspecific as to if ECC sticks can be forced to run in non ECC mode.
Most of the sticks I see on E-bay are ECC, I'm trying to get this thing up too 512K as xp
w/256K is thrash-o-rama. Going to poke around the BIOS tonight, see if I can turn ECC off
there. Thanks again for the help..
