PC2100 DDR ECC 266Mhz

I often see on the auctions, Ram advertised as: "PC2100 DDR ECC Registered 266Mhz Cl 2.5. -for use on Compaq Server models XXXX."
But the specs seem to suggest they will work on any machine that can handle it. I mean, this is the sort of Ram I need for my Tyan Tiger MXP. But just because it says "for use on IBM server models xxxx", does that mean it won't work on any other EEC server aswell? I usually get all sorts of RAM working by messing with the memory voltage jumpers, but I'm not sure about this case.

It should work fine, but I'd just get new DDR400 ECC, as the price difference is usually not that much.

Manufacturers have a list of RAM makers that are recommended, and have been tested with their motherboards. Thus, you have SuperMicro certified RAM. Or whatever. If you go to your mobo makers website, they will have a list of recommended memory for your specific mobo. As far as if it will only work in one or another, no, so long as it is the right type. You still can't use unbuffered memory if it requires it, even though it very well may be PC2100 DDR ECC Registered".
Tas.

Yes I know, thanks for your comments anyway. But thats not really what I was asking. I know which memory is "recommended" for my mobo, but I can usually get any ram to work, even if it isn't on the recommended list (play around with the memory voltage jumpers usually works).

I was suspicious though, that some memory may be programmed in some way, like a key, to only work in some brands, regardless of the global specs.

I guess the best way to find out is try. But I am sure I remember reading someting about it somewhere... Something to do with a chip on the ram being hardwired to only respond to a particualr brand of mobo, like IBM for example.

No memory maker better hardwire their memory for specific brands. The possible problem would occur if the pc maker (IBM, Dell etc. put something in the bios to only recognize their proprietary memory spd's but I have never heard of that before.

This means that the memory is standard but the bios has special codes that check for a certain kind of memory (Micron etc.) but I have never heard of or seen that myself. I have had people confuse registered and ecc memory for their Opterons but nothing about proprietary memory
