I need some good authoritative answer to memory density issue?

Question

I am in the market for DDR, I have a PC2100 256 megs already but I am confused as to its density and since both the original machine and assembled Dual Core took it in their stride I wonder if that Dual Core machine actually can take high density.

Upon visual inspection of the aforementioned memory module, it fits extreme high density chip to a tee; the stick has only 4 chips, one side only, no name, not even on the chips or PCB. That guy shoved me this 3 yrs ago knowing I wanted a 256 megs PC2100 for a mobo with KM400.

Answer 1

Older RAM may work OK on a newer PC, BUT it slows the whole system to a crawl. Only use add-in RAM that matches the existing RAM's specs.

Decide how much RAM you need FIRST. Then, go to:

Use their "Memory Advisor Tool" to identify your PC's RAM by make and model OR by Scanning your PC (Cool!).

Then, buy new RAM from them or Kensington, Ultra, etc. or buy locally.
