Rdram question

A friend of mine wants to buy 1Gb rdram for his 5 year-old pc (he doesn´t want to buy a new one). His motherboard is the Intel D850GB series (dunno the exact model i.e GBL or GB or GBAL) which supports up to 2Gb. I´ve found the board´s specs (the manual refers to both GB and GBAL) and it says it has 4 168-pin slots.
The rimms already on the system are samsung pc800-45 and only have a serial number on them.

Isn´t rdram suposed to be 184pin or 232pin only?
Does anybody know the exact kind of memory this board gets?

Thanks!!!
 
RDRAM does come in 168, 184, and 242 pin format I believe.

But first, find out exactly which motherboard he has. Download and run CPU-Z to find out what mother board you have.
 
there were some i850(G) that supported reg SDRAM, but the markings you gave PC800-45 indicate RAMBUS PC800 45ns modules. the 168 pin count refers to SDRAM, RAMBUS only came in 184 and 232 pin outs

i850 = 184 pin RDRAM (PC800 or PC600)
i850E = 232 pin RDRAM (PC1066)

PC800/PC600 16-bit w/2 notches 184 pin

PC1066 32-bit w/single notch 232 pin
 
I've found that the board's modeel is D850GB. I believ it takes 184pin rimm since there isn't a 164pin rimm as the manual says
 
you know that could be a typo in the manual too lol

i know the i850G(B) could use standard 168 pin PC100/133 SDRAM as well, but Intel was moving/pushing to RDRAM and i dont recall any MoBo (retail) being available.

the 32-bit RDRAM were short lived and Intel kicked RAMBUS to the curb when they got sued by them.
