It's great to
see how individual memory stacks up against the competition under stock
configurations, but we're also going to show how it compares when overclocked.
With performance in mind, we're going to compare the maximum overclocked results
of the various DDR-2 memory modules PCSTATS has tested in the past which are
listed below. Remember, just because memory is clocked fast doesn't mean it's
the best thing for a computer. Timings are also important, and getting the right
ratio of both is the real key to performance based overclocking!
Corsair Twin2X1024-8500 does
pretty well in the overclocking charts wouldn't you say? ;-) The
Twin2X1024-8500 C5 is not designed for low latencies, and this may explain why it
only hits 920 MHz with tighter CAS Latency timings of 4-4-4-12.
Does Corsair Redefine High Speed DDR-2?
It doesn't matter if you're a fan of DDR-2 memory or staunchly holding
onto those trust DDR sticks, it's the memory standard that will be with us for
the next few years and there is no changing that. Multi-core processors require
more bandwidth than conventional memory standards provide, thus DDR2 is a
The debate between low latency and memory bandwidth has been raging
almost since the dawn of computing, and the arguments are alive and well with
DDR2. There is no best memory, it really depends on what you want to do with
With dual core processors like the Intel Pentium D or Core 2 Duo, high speed DDR-2 memory
allows you to overclock much higher without the fear of bandwidth starving the
processor. With the Socket AM2 AMD Athlon64's wonky memory controller, high
speed memory is also easier to overclock. However, an Athlon64 core is still an
Athlon64 core, and it will always react positively to lower latency memory than
Corsair's 1GB Twin2X1024-8500 C5 DDR-2 memory kit is squarely designed for the
enthusiast at heart. With the ability to run at 1066 MHz by default, the
Twin2X1024-8500 memory is the definition of fast. To reach this speed though,
Corsair recommends a voltage of 2.2V which is pretty high, better to have good
case cooling 'cause this memory generates a fair amount of heat.
Even with the lax CAS latency timings of 5-5-5-15, the performance of the Corsair Twin2X1024-8500
memory kit at DDR2-800 speeds was decent, and it did not trail the low
latency memory by much. The Twin2X1024-8500 memory was able to run at 276 MHz
without any problems, yet I have the feeling it could have gone much higher if
the nForce 590 based motherboard had not maxed out first.
When we consider the benchmark and bandwidth figures for the Corsair Twin2X1024-8500 memory
running on a socket AM2 AMD Athlon64 FX-62 platform, at 276 MHz, it really
underscores what good enthusiast grade memory is capable of. Low latency timings
of 4-4-4-12 limited the memory to just 230 MHz however.
The Corsair Twin2X1024-8500 is highly specialized memory and if you're
looking for something that can reach insane clock speeds, look no further.
Hardcore overclocking is an expensive hobby and with a retail price of $264 CDN
($239 US, £125) for 2GB of DDR-2 it is priced at a premium, but it's about the
best you can get.
