so RD RAM kicks more butt than DDR RAM which kicks more butt than SD RAM which kicks more butt then RAM.

what about PC3200, PC2700, PC2100, PC1600, Non-EEC DDR.. what is up with those?

very clear to understand, thankyou NetRyder.

All of them are different types of RAM ... so to end your statement, it would be SDRAM kicks more butt than EDO RAM.

... FPM DRAM(don't ask its dead, so EDO for that matter) ...

The big downside to RDRAM however is that it's very expensive.

concerning the remark netryder had about ddr 266 being twice the speed... its actually a lot more marketing than anything else..
you will be hardpressed to see 2 times the speed difference in tests... though theoretically it is probably something like that
basically instead of having a read or a write every clock cycle (hence single data rate) you are able to do both (hence double data rate)
theoretical advantage not so much in clock speed of the memory but the amount of extra bandwidth afforded...
concerning bandwidth... rdram still kicks the pants off of ddr memory concerning bandwidth.. but with the advent of ddr II (operates like qddr internally) and qdr itself... we should see this move to sdram's favor by next year...
besides... rdram would not work with the current design of amd processors... intel has different length of data path (longer per se in leymans terms) and therefore NEEDS the higher latencies of rdram... but the extra speed and bandwidth help it overcome the drawbacks...

you also have to buy RDRAM in pairs just so you know can't just go out and buy a stick of 128 u have to buy two.

Hehe... i just sold 80 meg of EDO for $90 =P

I've read that it's all in theory too ... but I was just pointing out that the 266MHz DIMM was called DDR because it's theoretically supposed to be twice as fast as PC133 SDRAM.
