Mushkin PC2-5300 DDR2
 

However, having the number of different speeds of DDR 2 coming from as
many of the memory manufacturers as they are, DDR 2 should be quite
refined by the time most people migrate to it. During my testing, I
noticed absolutely no problems with this memory. I am quite impressed with
the results that I was able to achieve when overclocking the memory as
well.
