View Single Post - Is low density RAM faster than high density RAM?

Higher density has more to do with capacity then speed depending on type. The first cd-rs were only 60min. in length for audio tracks. The next generation was the slightly higher 74min. cd-rs soon to be replaced by the 80min. disks commonly used.

A double density floppy was 2.88mb instead of 1.44mb. When selecting memory you have to go by the type or types supported. Again some boards won't support a 1gb dimm which is a higher density then a 512mb although they are the same size. Memory frequency speed and CAS latency controls which memory is faster. DDR400 at 400mhz is faster then DDR333 at 333mhz. DDR400 with a lower set of timings like 2-2-5-2 is faster then the typical 3-3-3-8.
