Enthusiast calibre RAM usually only comes in one of two forms; high speed memory with lax timings or lower speed memory with tight timings. Making a decision at this crossroads will have a big impact on your PC's performance, and for most of us it's confusing as to which route is the best to follow.
PCSTATS has long been singing the performance praises of
low latency memory, but even modules that qualify have their limits. What's needed is more versatile memory, technology infused into DRAM so those little BGA chips run with tight timings at low latency speeds... allowing the holly grail of memory performance: Dual Channel DDR-2 RAM that cranks out the MHz while the timings are kept nice and relaxed.
This pair of Patriot's PDC22G8000ELK 1GB DDR-2
memory fits the bill, but these modules are so utterly new, so bleeding edge
that you can't have them. Sorry, this is a first glimpse at some very sweet
memory which is not quite yet available...
What sets this pair of PC2-8000 DDR2 memory apart from the
competition is that it's capable of three different frequency & timings settings.
Basically, these Patriot PDC22G8000ELK modules do it all; the
sticks clock to insane speeds for SiSoft Sandra folk and will also use
tight timings for those who want the absolute best performance out of their
PC rigs.
According to Patriot Memory, its
PDC22G8000ELK memory is rated for a CAS Latency of 3 at DDR2-667 speeds, CAS 4 at DDR2-800
speeds, and to reach DDR2-1000 speeds a CAS Latency of 5. Those numbers are good news
for AMD and its upcoming socket AM2 Athlon64 processor. The Athlon64 CPU traditionally reacts very
well with low latency memory, and on the other side of the fence Intel users can appreciate how
the memory clocks as high as the sky.
Have a look through the next couple pages of benchmarks, we'll be testing the
Patriot Memory PDC22G8000ELK 1GB modules at all three speed settings. Just
remember that these babies aren't quite ready for prime time yet, so there
are no MSRP details. When they launch shortly, expect the price to be competitive with
enthusiast memory of the same class.

Patriot equips its 1GB pair of PDC22G8000ELK memory with
grey aluminum heatspreaders which help protect the DIMMs from physical damage. In most
cases heatspreaders do little in terms of cooling. At modest speeds, memory
just doesn't get very hot. With increased voltages and clock speeds though,
enthusiasts do see some benefits from the added cooling so it's appreciated.
With Patriot Memory releasing the
multi-talented PDC22G8000ELK set, it's hopefully signaling a change to the other memory manufacturers as
well.
Enthusiasts are no longer fooled by high MHz ratings,
especially with DDR2. Timings have gone completely out the window, that negates
much of the benefits of running the memory at higher speeds. Other memory
manufacturers should follow Patriot's lead here and release memory that is
capable of reaching high speeds and running at tighter timings at slightly slower
speeds.
According to Patriot, it remarks and uses Elpida
PM64M8D2B-25AEL DDR-2 DRAM modules on its PDC22G8000ELK memory modules. Please
note that DDR2 DRAM modules are very fragile and if the memory you're using
comes with heatspreaders, it is not advisable to remove them! Doing so will void
the warranty and if you kill your memory you're on your own!
