Hi which of these types of RAM are faster?

thanks

The manufacturer specifications will state the data transfer rate capabilities. The larger the number = faster.

That's too complicated. You have to know how to read and stuff.

<jk> rdram is the fastest with a Pentium 4 </jk>

oh, did you see what i did there

for the most part, DDR3 is faster, but doesn't have any real world benefit yet
(DDR2-1066 is faster than DDR3-800)

timings can also plan a big part in the overall speed of the RAM

As a rule of thumb (without getting too technical) you can look at frequency speed and CAS timing. DDR2 800 with CAS 4-4-4-10 will be the same as DDR3 1600 with a CAS of 8-8-8-20. The frequency is doubled, but so is the CAS timings. But where DDR3 starts to pull ahead is the DDR3 1800 and DDR3 2000 because the bandwidth is greater than low CAS DDR2 can make up for...But the most important thing to remember, is that at best this will only give you ~3% speed increase. you'll pick that up in synthetic benchmarks, but not in real world games. And high speed DDR3 is still expensive. better to spend your money on a videocard upgrade.

I think ddr3 mostly benefits am3 and socket 1366(i-7) set up for am2+( am2+cpu"s on ddr3 motheboards) or 775 the benefits are neglegible.
