AK31 - High density or low???

[Melissa2008B]

I have a box that was built by Atlas Micro about 6-7 yrs ago when they were still in business.

It has a Shuttle Spacewalker AK31 mother board with AMD XP 1.6 CPU.

( I'm only an intermediate user but was formerly an electronics tech from the late 60's to early 90's )

I have 512 megs RAM in there now and need to add 1gb.

On ebay they have some that looks right but says it is high density and not compatible with everything.

Can anyone point me where to find out whether this mother uses high or low density RAM? It's not in the manual here, I looked.

6-7 years ago, that could even be as old as EDO ram which is more $$$ than upgrading the motherboard and CPU. Also it could be (though highly doubtful) RAMBUS RAM which is also very $$$. If it's 240 pin DDR then it's still available at decent prices. Interestingly enough Dell has a sale right now where you can get a Q6600 processor, 3GB of DDR2 667, i forget what size harddrive... anyway it's the whole computer minus the monitor for under $450. The only catch is that it has onboard graphics rather than a video card.

As far as finding out what memory your existing motherboard uses, are there any identifying marks on the memory itself?

Here's something more specific from the manual:

"The AK31 mainboard has four 184-pin DIMM slots that allow you to install from 64 mb up to 4GB of system memory.

Each 184-pin DIMM slot can accomodate 64MB, 128mb, 256mb, 512mb, and 1GB of PC1600/PC2100 compliant 2.5V single or double side 64 bit wide data path non-ECC DDR SDRAM modules."

Does that help?

I'd have to pop the case ( don't have time this morning ) to get the actual numbers off what's in there...

OK, I finally got the time to open the case and look. What I have in there now is: kvr266x64c25/256
