When I boot up into the bios it says RAM configuration is NON-ECC. This is a pre-built Gateway Preformance 1400, Rambus computer. I know it's PC800 Rambus, I've looked at the chips. I can tell on DIMMs and stuff, but how do you tell on RIMMS?

You can look up the chip model numbers online. Or you can post them here and we can look them up.

Another way is to use a SPD chip reading program. It will tell you what the memory is.

The one above is a DOS based program and you need to run it from a DOS prompt.

However you need to use one of the following commands after the filename:

all: Show all fields and descriptions
dump: Dump SPD Memory, [Bytes]
inf: DIMM general information
mft: Show manufacturers list
help: The command list screen



Most modern memory PCBs have a SPD chip on them. Some forms of SDRAM will not. Example. I am running PC133 on my laptop and the memory does not have a SPD chip on it.

So you would only get a disply like this:

On DIMM SPD Tools. Version 1.2 FREEWARE. (C) 2001 by Dmitry Poltavtsev.

DIMM number 0: Not Inserted or no SPD module
DIMM number 1: Not Inserted or no SPD module
DIMM number 2: Not Inserted or no SPD module
DIMM number 3: Not Inserted or no SPD module


But for your RDRAM it should work.

I have just tried using spd_tool on my gigabyte 7vrxp and was informed that spd_tool a) did not work b) it works only with specific chipsets. Any other ideas on a SPD chip reading program?
