Ddr 266 ?

Is DDR 266 called PC-2100 ? n/m i found out

DDR266 = PC1600
DDR300 = PC2100
DDR333 = PC2700
DDR400 = PC3200
DDR433 = PC3500

Is this correct?

Erm, nope - not as far as I know.

133FSB->DDR266=PC2100 is what I'm using. I've seen the calculations of all the other's you've listed. To get the DDR FSB rating of the memory you want - eg PC3500 - divide 3500 by eight to give you the double the actual FSB frequency. This way PC3500 memory work out at running on a 437Mhz (read 433Mhz for this purpose) bus.
So, for your memory calcs,
DDR266 = PC1600 should be 2100
DDR300 = PC2100 should be 2400
DDR333 = PC2700
DDR400 = PC3200
DDR433 = PC3500

So for 1600 read a 200Mhz DDR fsb, or running at 100Mhz actual.
Sorry for raining on your parade cullam3n - I don't mean to be a pedant or anything Hope this helps anyway.

Yep that is it.

Notice I said "Is this correct" because I wasn't sure. But thanks for pointing out my mistakes. =)
