Just to add a bit, (well, a lot
, actually), of info to MD's reply above...
Since all memory is 'backward compatible' I would suggest that you spend the few extra $ now and buy the faster PC3500 ( which can run at 100 MHz, 133 MHz, 166 MHz, 200 MHz, or it's rated 216), knowing that it will be 'good-to-go' on your next mobo upgrade.
Or, even better would be PC4000... and it is NOT that much more expensive.
You will also realize an immediate benefit with the faster memory now, because you will be able to run it in your current system with VERY
'aggressive' memory timings.
I have never regretted spending good money on good memory.
I have all-to-often regretted spending ANY money on on 'no-name' memory.
Don't skimp by buying 'no-name' bargain memory... it is very false economy.
Just in case you are not familiar with this new DDR thing, this little chart compares the new 'PC' rating system, to the 'DDR' rating, to the actual 'Maximum MHz' that the memory is 'rated' to run at....
But the same 166 MHz = 333 DDR applies to CPUs and mobos as well.
PC# vs. = DDR# vs. = MHz
PC1600 = DDR200 = 100Mhz
PC2100 = DDR266 = 133Mhz
PC2700 = DDR333 = 166Mhz
PC3200 = DDR400 = 200Mhz
PC3500 = DDR433 = 216Mhz
PC3600 = DDR450 = 225Mhz
PC3700 = DDR466 = 233Mhz
PC4000 = DDR500 = 250Mhz
PC4200 = DDR533 = 266Mhz
PC4400 = DDR550 = 275Mhz
PC4500 = DDR566 = 283Mhz
PC??00 = DDR600 = 300Mhz
please note that the 'DDR rating' is always exactly double the 'actual speed in MHz' that it was designed to run at.
DDR (or Double Data Rate) memory is also SDRAM memory, but DDR SDRAM is able to read info or 'data' on BOTH the rising and falling edge of a pulse...
Hence the name... "Double Data Rate, Synchronous Dynamic Random Access Memory" (or DDR SDRAM for short, or, usually, just DDR )...
SDRAM can only read it on one edge of the pulse.
But, DDR266 is still only running at an actual 133 MHz
The same thing applies to processors, and mobos, that are rated as 166/333 (or, to use the Marketing boys description, as a '333 CPU'
... a '333' processor is running at 166 MHz. Period. End of story.
Only on the very newest, fastest, mobos will you ever find any setting in your CMOS Setup that allows you to set it to '333'...
and that's because it ACTUALLY RUNS AT 166 MHz
I know that it's extremely confusing, and frustrating, and it certainly was to me at first, but I really DO HOPE that this helps SOMEBODY with understanding this VERY confusing nomenclature.
