Hi Jdaasoc; Re the price ratio for PC800 vs PC133. Your figures (which show RDRAM 3x the price of SDRAM) are lower than the Smsperling data for a number of reasons:

(1) You are using 128MB sticks. It turns out that this is the cheapest variety of RDRAM in terms of dollars/MB, while SDRAM is relatively cheaper at larger sizes. Odd thing is that SDRAM is also relatively cheaper at the 64MB size, probably because of a combination of SDRAM volume with the RDRAM heat spreader costs.

(2) You are using Samsung memory store pricing, and these prices are considerably higher than average for SDRAM, while lower than average for RDRAM. As to why that is, I don't know. I'd love to do a long term chart of PC800 vs PC133 as priced at Samsung, but I don't have the data. In comparison, Smsperling has the data going back over a year.

If you decide to start charting the price of registered DDR DIMMs, I suggest that you start with a size considerably larger than 128MB. It would a bit nuts to use registered parts for anything other than testing in such a small size. 256MB registered sticks are nearly the same price as 128MB registered sticks, and would make a more rational choice for a PC server:

DDR 256MB 32X72 ECC REGISTERED 200MHZ PC1600 184 PIN SDRAM $439

By comparison, the cheapest PC600 ECC 256MB stick I saw on Price watch was $389. So DDR is still more expensive, but what did you expect? DDR hasn't been out very long has it.

P.S. Just for grins, I bought a small amoung of ETYS this morning. Not going to hold it longer than two weeks.
