[ale] Why is RAM is so expensive?!? Anyone know an inexpensive source?
I did some research on this about a year ago and also contacted some vendors for answers (mainly Dell and Cisco whom I was already dealing with), and the answer is somewhat simple - whatever is in production "now" will benefit from from the production improvements on previous generations and larger volume, and will be generally cheaper than what was in production "before", even if that "before" is still being produced. So if the standard being produced is DDR3, and even if DDR2 is still being produced, DDR2 in this case is more expensive to produce and in less quantity, and will thus be sold at a higher price point.
I don't have any white papers to back this up - it was research for upgrades of systems vs. replacements; but in most cases replacements were deemed cheaper than upgrading and I found the same to be true on my own systems as well. While not cheaper, per se, it was more cost effective to replace a system with 8gb ddr2 ram with a 32gb ddr3 ram motherboard and new cpu, than it would have been to upgrade the ram to 16gb of ddr2 ram.
In smaller quantities, it is probably better right now to build out a system with the maximum ram (say up to 128gb) as it will very likely be cost-prohibitive to upgrade it later. That said, it's definitely not worthwhile to invest in the 32gb dimms on server-class machines to get 2tb+ of ram from a machine when the cost of doubling the ram exceeds the cost of buying a second machine with the same amount of ram as the first.
Just my two cents though.
