Almost annually, we do a "round-robin" with computer systems in my family. I build a couple systems every couple years. this year, mom gets her D850MVL (PC800 Rambus) system replaced with a Prescott 3.4E system. My brother sixty miles away has a similar system (same mobo and RAM). He needs more memory -- using the system mostly as an HTPC.
Mom's Rambus system has 512MB with four 128MB modules (four slots, total), and Bro's system has 512MB (2 x 256MB) with two slots filled with "CRIMMs" -- ready for two additional modules to replace those CRIMMs.
Meanwhile, as if God was giving me help, I went to dinner at a friend's home, whereupon my friend offered me several boxes of cyber-junk, including two motherboards with Rambus PC800 128MB modules, and a pair of 256MB PC800 ECC modules. All the other modules -- those in the family and those conveyed to me by my friend -- are non-ECC.
If I can mix ECC with non-ECC, Bro can have 1GB of memory in his system. Otherwise -- the best we can do is 768MB using all non-ECC modules.
Since the Intel D850MVL boards are now archived at Intel with no further support, I could only confirm that all modules -- non-ECC and ECC in my possession -- will work with the motherboard.
I thought that I had read some years earlier, and with regard to the Rambus systems, that you could mix ECC and non-ECC memory so that the motherbaord would treat all the modules as non-ECC.
Does anyone have any further insight on this issue? I rather doubt that I'll damage anything by testing the ECC modules in my brother's (or mother's) system and running MEMTEST86+ against it to verify that it works.
