Bilow... When you quote PriceWatch, why don't you give us this additional information? ... RDRAM Pricing on Pricewatch From YAHOO by: h0db (40/M/Tysons Corner, VA) 06/13/01 10:04 pm EDT Msg: 299914 of 299931 RDRAM pricing moves inexorably on pricewatch.
PW does list them yet, but there are now 2 pages of 512MB RDRAM modules, if you search for "RDRAM" and "512MB"-- almost twice as many as there are for PC2100 512MB. The lowest price is $612. Almost all of these are using 256/288Mbit chips; they are the only commodity DRAM using the densest chips in production. On an i850/P-4 with two RDRAM channels and 4 RIMM slots, you can install 2GBs of memory (without repeaters) and stay within the 32-devices per channel limit.
256MB RIMMs are up to 12 pages--more than PC2100 256MB modules. The price has fallen to $144.00 for PC800 from one vendor, and into the $150s from others--a steep drop, and all time low.
128MB RIMMS are up to 13 pages, another all time high. The lowest price is $68 for PC800--for the first time, denser RIMMs are costing less per MB than 64MB and 128MB RIMMs.
The other thing I notice is that 95% of the RDRAM being offered is PC800. PC700 is legacy--this bin-split does not officially exist anymore. PC600 is rare, and mostly uses old 64Mb chips.
A nice thing about RDRAM is that you can buy the cheapest PC800, even "generic" and know that what you are buying is just as fast and just as compatible as name brand. This is not true for PC133 and DDR-SDRAM-- you have to pay attention to the CAS Latency and the speed grade stamped on the chips, since each manufacturer is making it a little differently (thanks, JEDEC). The vast majority of PC2100 out there is CAS3 or CAS2.5; very little of it is CAS2, and most of that is binned as "PC2400", a meaningless distinction since there is no official speed grade as such---and it costs almost twice as much as "generic" PC2100. |
