wrong forum, go ahead and lock

http://www.utdallas.edu/~melvinc/ramback.jpg Back of stick

Picture of it - the stick in question is the one on top in the first picture (took a picture of it next to a regular stick of PC100). It's supposed to be a 128MB PC100 stick, I'm guessing from the looks of it a double sided stick, but I can't get it to work for the life of me. When I stick it into my P2/SE440BX-2 board, it beeps once, then beeps 3 times, then beeps 3 more times, then one more beep. (Refuses to boot/post) When I stick it into my BH6, it boots but if I have any other RAM in there it treats the other stick like it doesn't exist. (I have a 256MB PC100 stick and the bios doesn't even recognize it) The back of it has a Compaq sticker and a compaq barcode that says 49105. What's up with those two chips on the bottom of the row of 9? I was thinking possibly the stick is PC66? (The P2-400 is 100mhz FSB iirc, and the BH6 is running a C2-566 that has a 66mhz FSB - it works in the BH6 but not the P2-400)

Sorry I know this is kinda the wrong forum but I'm ready to throw my monitor out the window :| Hell I'd be willing to paypal someone if they can verify what type of stick this is (markings on the actual chips is MT 48LC16M4A2)

could be ecc... if only some memory is ecc, and others arent, sometimes the system wont post

 

[fatkorean]

is it ecc ram?

 

[Angrymarshmello]

I put ECC on in the BIOS of the P2 but it still didnt post...just kept beeping at me

 

[Angrymarshmello]

fk - no idea

 

[TheBoyBlunder]

Either what gobadgrs said or it's double sided and your boards don't like double sided. (I'm stretching, I know)

/obligatory wrong forum comment. (sorry, it was obligatory)

 

[fatkorean]

umm you could look up the beep codes for your bios and go from there

 

[Angrymarshmello]

Weird, I just ran a test program and the RAM came up as:

128 Mb (130 424 Kb) DIMM3: 128 Mb(Unknown,EDRAM,7 ns)

I've never even heard of EDRAM Thanks for the help guys

hrm, someone mailed me some 256mb instead of a 128 on accident once :-\ didn't think they'd be that hard to tell apart

That "R" at the end of the module code might mean it's registered (and from the number of discrete chips, ECC as well).

edit: Google groups for "PC100-322-620R" turns up a couple of entries for registered (buffered), ECC RAM.

Micron has MT48LC16M4A2 listed on their site as 64MB, if that helps.
