pcstats test methodology
pcstats
tests ddr memory on amd athlon64 systems only because intel has effectively made
the transition to ddr2. enthusiasts usually keep to the bleeding edge, so fast
ddr memory is useless for the intel overclocker looking for more
juice.
on amd
test systems we're only interested in seeing how high we can go with the memory
running 1:1, as running with other dividers puts the overclocking bottleneck
elsewhere, not with the system memory. We usually run DDR RAM latency at
2-2-2-5, or the memory's tightest possible timings, as quick access is important
to the CPU design. However in cases where memory is built to run at high speeds
with lax memory timings, we will run the benchmark tests at the manufacturer
specified timings. Not doing so would put high speed DIMMs at a disadvantage
since the memory may not be designed to run at tighter memory timings.
As we
move into the benchmarks a quick explanation is in order as to why the results
will show minor performance gains due to the faster memory speeds we're testing.
With previous platforms, increasing memory speed often meant also increasing the
bus speed between the processor and memory. Since the memory controller is
integrated into the Athlon64 processor, overclocking memory does not increase
the speed of data moving to and from the processor any further, since there is
no bus. To really get the most from your memory overclocking, you must also
increase the CPU speed so it can handle the increased memory bandwidth. The
reason why we do not do this during testing is because CPU speed will affect the
benchmarks and that would not allow the results to be directly comparable to
previous tests. By keeping the processor at approximately the same speed for all
tests, we are seeing the real world benefit from the increased memory frequency
alone.
Overclocking Athlon64s is a bit different since there is
no more bus between the memory and CPU. On your system, make sure you increase
the speed of your processor so you can get the most out of both the memory and
CPUs!
With that out of the way, let's get started with the
benchmarks!

At stock speeds, the Crucial Ballistix PC4000
DIMMs perform the same as the competition. When overclocked we see a slight
boost in performance but not much.

It should
be no surprise that the memory bandwidth for all DIMMs at stock speeds is about
the same. All memory is running the same speed with the same
timings.
