RD Ram

I'm toying with the idea of upgrading my amount of ram. I came aross this for my board>

MODULES MUST BE ORDERED AND INSTALLED IN PAIRS. This motherboard supports both ECC (X18) and non-ECC (X16) RDRAM. ALL RIMMs MUST be of the same type and installed IN PAIRS.

What does it mean by the same type? Is it talking about x18 & x16? Does manufactorer come into it? How do I tell if mine is x18 or x16?

When it says pairs,

it means that you are going to need to buy two sticks that are the same in every possible way. Speed, size, and probably brand also.

I used to use RD Ram, and made the mistake of just buying one stick :(

Your sytem wont run unless you have two sticks that are the same.

By the way, because it supports both ECC (X18) and non-ECC (X16), you would get a pair of one of the two types. not one of both.

Half true. When it talks about pairs you must have two sticks that are equal in MB (meaning two sticks of 128, 512, etc.). They can vary in speed (600MHz, 800MHz, etc.), however the speed will step down if you have one stick 600MHz and one stick 800MHz. Yes, it is recommended that you buy the same speed and manufacturer, although it is not a must.

ECC sets check for errors.
non-ECC doesn't.

800MHz is the speed of the RAM. Most SDRAM is ~133MHz. RDRAM is 600MHz, 800MHz, etc.

I have four 128MB cards of 800MHz RDRAM.

go into the bios of ur motherboard it will tell u if the ram is ECC or non-ECC from you buy the ram
they usually come in pairs...when they sell them...if not just pick up 2 of the same thing....

I'm not sure about RD ram, but I remember back in the day when putting together old 486 comps outta spare parts, pairs meant EXACTLY the same, brand and everything.

I hope not because when I get more it is going to be the cheapest I can find. Suppose I should make sure first though. Oh I took the stick out but it did not tell me whether it was ecc or non ecc.

if you can find the manufactuer and the part or seriel number on the stick then you should be able to find all the specs for it on the manu's web site
