I have an old HP Workstation xw4600 (actually 2) that I am still using until I get a more stable living situation. These workstations use DDR2 memory (PC2 - 6400 ECC, Unbuffered 800mhz). It has been the most expensive memory combination for this class of memory I have ever seen. DDR2 has all but been classified as dinosaur memory, but still - in 2016, even after two generations of memory has surpassed it - I cannot find it for sale ANYWHERE without the prices just as high as it was when it was new. These prices that I see do not reflect the desirability of DDR2 - I don't know WHAT they reflect but they are way out of line! There has been discussion, in the past of why DDR2 prices skyrocketed (manufacturer fire) but how about NOW. Why is it in 2016 that DDR2 isn't dirt cheap, dig through the pile at the flea market price??? I'm seriously looking at just throwing my system out and buying another - would be cheaper than the 6 gigs of DDR2 that I've been waiting for to come down in price forever.
