This dual channel kit from OCZ runs at some very impressive speeds.
The specification is DDR 533 (266mhz) at CAS 2.5. The EL in the product name
stands for Enhanced Latency, hence the CAS 2.5 specification. In practice, we
found it impossible to reach 266MHz with either a K8T800 Athlon 64 motherboard,
or an LGA755 board with an unlocked engineering sample Pentium 4. To fully exploit
this memory, you would need a K8T800 Pro or nForce 3 250GB motherboard with
PCI and AGP locks to reach a 266MHz Front Side Bus.
Before buying extremely high specification memory, you need to be sure of the
limits of your motherboard so you can buy DIMMs rated for speeds that your board
can achieve, potentially saving you a lot of money. As with all overclocking,
nothing is guaranteed. The price per megabyte of this kit is very high, and
the actual purchase price is approximately the same as a Gigabyte of Kingmax
RAM for example. However, if you are sure your board can make use of the high
speed, this kit could provide better performance than a Gigabyte of slower ram
in some circumstances.
The DIMMs themselves are covered with very ordinary copper heat spreaders,
which tarnish almost as soon as you look at them. In fact, our test samples
needed a quick going over with a little Brasso before taking the photograph.
