has come once again to see who has the best and fastest memory on the block!
Corsair is laying it all on the line with their new XMS PC4400 memory. For those of you mathematically challenged, like I am without a calculator
at my fingertips, PC4400 means that this memory is certified to run at an
incredible bus speed of 275MHz, or 550MHz DDR. That is a screaming bus
speed, and only a few manufactures even make a motherboard that can actually run
stable at that speed. As for the CPU, only the P4 can guarantee you success, but
only with the lower end P4 "C" such as the 2.4C and 2.6C. Unfortunately, Intel has
already discontinued the 2.4C and it's only a matter of time before they work
their way up the ladder as they release faster CPUs. This means the days of
extreme bus speed overclocking is limited. Therefore, with only a select few
motherboards able to handle extreme overclocking along with processors that are nearly extinct,
PC4400 memory is going to be short lived at best. There is also no standard for
such memory, so in order for a company like Corsair to put their reputable label
on it, it has to be hand tested to ensure that it can handle such speeds. This
means only the best of the best memory is selected, and then only a small
percentage will every carry the PC4400 label. Sound like an expensive process?
You bet it is, so expect PC4400 to carry a hefty price tag. With that said,
let's take a look at this "premium" memory and see if it lives up to our
kit we received directly from Corsair is a perfectly matched pair of 512mb TWINX
PC4400 memory modules. Here are the official specs:
Tested at DDR550 (275MHz) on an Asus
Tested at JEDEC-standard latency
settings (3-4-4-8) for optimal memory bus speed
Optimum Canterwood performance
achieved at high bus speed and relaxed latency
Test voltage: 2.75V
That's pretty much it as far as specs
go. However I want to point out the bit about pre-testing. Corsair only uses
ASUS motherboards for testing their memory. In this case, an Intel 875 "Canterwood"
chipset based ASUS motherboard. This is very important to know because if you
own anything but a Canterwood based ASUS board, this memory may or may not work for you. Talk
about specialized memory!
