can i buy ddr2 1333MHz?
"General Schvantzkopf" wrote in message . .. On Thu, 09 Oct 2008 14:23:01 +0100, Beemer wrote: I want to buy 2 x 2GB of DDR2 (not DDR3) 1333Mhz memory. Who makes this and can I buy it in the UK? regards, Beemer Why do you want 1333MHz memory? The bottleneck in a Core2 system is the FSB not the RAM. The FSB is only 64 bits wide which means that the fastest RAM the bus can handle is the FSB speed/2 (because each DIMM in the pair is also 64 bits wide). The fastest FSB speed available is 1600 which translates into DDR2 800. DDR2 1200 is widely available. 1200 is a 50% overclock of the FSB which is more than enough. BTW most motherboards have a maximum FSB of 1333 not 1600. Your reply is logical and I guess I was lured into 1:1 by Giga-Byte's recent 1333 bios release statement. Having used computers and programming before the "personal computer" and passing college courses including "solid-state electronic techniques" I do wonder whether I should try to keep up with you younger folks! thanks, Beemer |

I've been designing computers since the 1970s. Avoiding bottlenecks is rule #1 when designing any system. The principle is obvious, if you think of a six lane super highway that narrows down to a two lane country road, where would you spend your money if you wanted to increase traffic flow where would you spend your money? You could spend billions widening the super highway to 8, 10 or 12 lanes and not one more car would be able to flow through, but any money spent on the cow path would increase traffic flow significantly. In an Intel system the FSB is the cow path and the memory interface is the superhighway. They are doing away with the FSB in the next generation so faster memory will be useful then, but it's money down the drain on the current generation. |

I started with magnetic core memory on a Univac 1050 in 1965 B^) Phil Weldon WOW!!..........you are really old Phil........:-) The first core memory boards I worked with were on those Avis car rental "Wizard" terminals in the early-mid 70s (Some independent Avis dealers used them until the early 80s).......Think they were about 100-128k, about 2'x2' in size and probably cost in the area of $20,000-25,000 IIRC. They worked with old IBM Selectric I/O terminals on a nationwide polling network. Ed |
