The speed probably wouldn't work, but more than that, the 1950 requires Fully Buffered Registered ECC DIMM's.  Non FB DIMM's will not fit.
Hi all, I found some gigs of PC2-3200R DDR2 ECC REG Ram. But I've in mind, I can only use 4200 or 5300. Is that right? Or can I put my 3200 in (with a Little loss of performance)? If not, which ram can I use? Does it have to be ECC? Or will "normal" Desktop rams work? Thanks for help and sorry for silly questions in bad english ;)
PC2-3200R in PE1950 possible?
