There are currently no amd motherboards that support rambus nor are there any plans on making any. So no, you can't put rambus on an amd system.

so does it give major advantage over pc mem?
support rambus is right. intel basically gave the computer market to rambus on a silver platter, but rambus could not keep up its end and eventually intel cut ties with rambus and left them floundering.Dukemurmur said:
rdram had great performance for its mhz. it is still a capable performer, but there is no upgrade path for it. the i850 is the top of the line consumer rdram chipset. the i860 for xeon boards is the only workstation/server rdram chipset. both of which are several years old and cannot truly compete with current technology like dual channel ddr and DDRII.

When wil AMD support DDRII? I have been wondering this for quite sometime now.
the i850 was for pentium 4 processors. it was limited to a top range of approximately 185-190mhz. it offered much higher bandwidth per mhz than ddr, but its lack of ability to raise the mhz speed led to its downfall. ddr continued scaling while rdram was stuck. intel sensed this and moved along choosing to continue with ddr based chipsets.TheTick said:

This is an athlon 64 board yes as i think that i have heard that they arn't going to make any more socket A for a long long time to come.

What performance increases can we expect from DDRII over normal??
DDRII in and of itself will not provide a performance increase. the move to DDRII is to facilitate further speed increases in mhz, not efficiency. DDRII and DDRI at the same speed should result in approximately the same performance. we have reached the limit of DDRI's mhz capability, DDRII is just getting warmed up at this speed.

Acctually rdram had a much lower banwdth per mhz. It ran at whopping 300, 400, and 533mhz when it was used by intel. Like ddr it also gave off 2 transfers a tick. Plus it was run in dual channel while ddr was stuck in single channel. The reason for the llow bandwidth per mhz was because rdram had a 16bit bus while ddr has a 64bit bus. Its lack of ability to scale bandwidth fast enough upward along with high prices did lead to its downfall. By the time rdram started moving to a 32bit bus it was too late. Its bandwidth could not compete with dual channel ddr to power p4's 800 mhz system bus.Maxvla said:
