Because our regular Pentium 4 memory testing equipment was not
available for this review, we tested the PC3700 DDR on a Pentium 4 3.0C platform which is
somewhat restrained in the overclocking arena.
Sticking the OCZ PC3700 DDR memory into the Albatron PX875P
Pro motherboard we first tightened the timings all the way to 2-2-2-5, but
unfortunately the memory wouldn't take that. After a bit of tinkering we were
able to get the memory to run at 2-2-3-6 at stock speeds which is pretty good
for high speed DIMM's.
We abandoned the thought of running tight timings after playing with
different settings for a while since the highest we run the memory at CAS2 was
a mere 210 MHz. At SPD (2.5-4-4-7) the memory was much more friendly, and we could finally
start to push it. Amazingly, we were able to hit 230 MHz FSB
with no problems, and did not have to increase the voltage past 2.7V! Unfortunately we could
go no further. I'll update this review a bit later when the Pentium
4 2.4C test system is available once more.
While Athlon64 sales are slowly ramping up, a large
percentage of the enthusiast market have already adopted it as their own, and that's
why we're now also conducting Athlon64 overclocking tests. Using an Athlon64
3200+ and the Asus K8V-DLX motherboard we were interested in seeing how tight
the memory could run at stock speeds. Like the Pentium 4 system, the tightest we
could run was also 2-2-3-6, definitely not bad for a high speed DIMM.
Unlike the Pentium 4 system, we had a lot
more luck overclocking the OCZ PC3700 DDR with the Athlon64. At 235 MHz, the memory ran into a
few stability problems, but upping the DDR voltage to 2.8V solved all those quirks. In
the end we hit a very respectable 243 MHz.
