If you plan on building a computer system with the
idea of overclocking it to the next level, it's really the memory you
choose that determines if you're going to be successful. Good
quality enthusiast memory is like the key to unlocking the
potential of your computer. Of course, just increasing the frequency of the
system memory will only net a modest performance gain from overclocking. Modern computers are designed for a certain amount of memory-to-processor bandwidth, which happens to be just satisfied by the DDR2-800 standard. If memory bandwidth alone is increased, the computer just has more bandwidth than really needs.
The magic happens when you start to overclock the rest of the computer in line with the memory. With memory that can run at high speeds, it guarantees that your PC will never be bandwidth limited. If you remember back to the Pentium 4 days, running SDRAM or single channel DDR severely limited the processor's performance because the memory just couldn't keep up.
Now a days, when it comes to overclocking
the socket AM2 AMD Athlon64 or Intel Core 2 Duo processors, you're in luck
because there's a ton of enthusiast friendly DDR2 memory on the market. From super high speed memory to low latency DDR2, whatever the flavor you're looking for, you'll find. Of course you can find memory from the big enthusiast memory manufacturers like Corsair, Kingston, Crucial and OCZ. Others like MA Labs Supertalent are challenging the old guard with surprising set of enthusiast grade RAM. In this review, PCSTATS will be testing Supertalent' 2GB kit of T10000UX2G4 modules, paced at a friendly DDR2-1000 level.
SuperTalent 's latest memory, a pair of 1024MB T1000UX2G4 modules, has some pretty impressive specifications. The 2GB PC2-8000 memory kit is rated to run up to 1000 MHz with CAS Latency timings of 4-5-4-12. This 2GB SuperTalent T1000UX2G4 dual channel memory kit retails for about $464 CDN ($400US, £204 GBP), and that is pretty competitive for memory of this caliber.

The SuperTalent T1000UX2G4 modules are not as flashy as
some of the Corsair DOMINATOR DIMM's PCSTATS has seen recently, but then who
really cares... memory is memory, and it's the DRAM on the inside that actually matter. SuperTalent place two blue aluminum heatspreaders on either side of the DIMMs, these draw heat away from the DRAM and protect the stick from physical damage. With higher voltages being applied to overclocked memory, we found that the heatspreaders here performed well. At stock settings, they're really just for show.
The SuperTalent T1000UX2G4 dual channel DDR-2 2GB kit is rated to run at DDR2-1000 or PC2-8000 speeds with memory CAS Latency timings of 4-5-4-12, at a voltage of 2.2V. The SPD is set to JEDEC DDR2-800 standards, so don't forget to manually adjust the timings when tweaking and overclocking.
Please note the SuperTalent T1000UX2G4 does not support EPP. Not a big deal though, EPP is more of a newbie thing and if you're overclocking you're no doubt a vet. ;-)
PCSTATS Test Methodology: On Intel Socket 775 Core 2 Duo test systems, we're only interested
in seeing how high we can go with the DDR-2 memory running 1:1, as running
with other dividers puts the overclocking bottleneck elsewhere and not with
the system memory. The DDR-2 RAM latency must run at its lowest possible
setting, as quick access is more important to the CPU design. Just for arguments sake,
we will also be conducting overclocking tests to see how high the
memory will go with lax timings (5-5-5-15), although we will only benchmark the system with
the tight memory timings mentioned above. Let's get started and overclock these
