HD Mem vs LD Mem, help a brother out

First of all: Yes, I am six weeks from obtaining a four year degree in Computer Science. Yes, I do hate computer hardware and everything involved with it (we'll call it burn-out). Yes, I have tried to research this elsewhere on the web.

Ok, so I am building an at-home PC for my boss (he's giving me his old one which I am in turn giving to my sister... typically I would never do this for anyone outside my fam) and I order an ASUS V7A600-X motherboard and a gig of (what I thought) was mitsubishi PC2700 memory. It turns out that the scheisters at BuyAIB.com gave me the fine print workover and sold me some Mitsubishi (or major brand) memory. Fine, whatever, memory is memory anyway and we paid them an extra four bucks to actually test it before shipping.

I get all the parts, put the PC together, and boot up the machine to find that of the 1 GB stick in the board, all we're seeing is 128. Nice.

Well apparently this issue comes from ASUS boards and High Density memory. Question 1: Has anyone experience a similar problem/issue to this?

So my thoughts are, if this memory doesn't work in the ASUS board, I can just stick it in my ECS board at home, because I was meaning to put another gig of memory in there anyway for EQ2's soonish release. But now I'm thinking: (Question 2) "Is the 512 mb of memory I already have in there High or Low Density? Is there an easy way to tell?"

Any help, light shed, or direction in any of these areas is greatly appreciated.

The easiest way to tell is probably to look at the serial numbers that are on the DIMM''s memory chips. Go to the manufacturer''s website (manufacturer should also be printed on each chip) and search for the serial number(s). There should be info there telling you whether it is high-density or low-density.

As regards the motherboard not liking the memory:

Intel had similar issues with RAMBUS when they introduced RIMM 4200. These RIMMs had higher density memory chips (and didn''t need to be installed in pairs), but only worked in certain motherboards.

I''d say try the memory in your board (provided there aren''t voltage issues or similar things that can lead to you frying stuff) and see if it works.

If the Asus board doesn''t like the memory (and the memory isn''t faulty), it doesn''t like the memory. There''s nothing you can do but buy a different brand.
