OCZ PC2700 EL Dual Channel Memory 2x 256MB Kit
It was only
a matter of time before manufacturers and their marketing departments jumped all
over the "dual channel DDR" craze created by nVIDIA's nForce2 (Athlon) and
Intel's Granite Bay/Springdale/Canterwood (P4) chipsets. In all honesty I
understand why they did it, after all if you can charge more for DIMM's "tested"
to run properly together why not do it? Like everything else in life it always
all comes down to money.
we're going to be checking out OCZ's PC2700 EL (Enhanced Latency) memory kit
which consists of two 256MB modules intended for dual channel DDR
motherboards. OCZ equip this memory with black aluminum heatspreaders
which are supposed to help with passive cooling, but considering that there
are four DRAM's per side I don't think this is really all that necessary. The black
aluminum heat spreader looks sleek and at least offers some static protection to
the precious DRAM's below.
Of course, being our usual
curious selves we wanted to see what was under the hood on these PC2700
modules. With care and caution we pried the heatspreaders off and found four 256Mbit DRAM's per side with a OCZ 252US
X4W560840A-40 markings on them.
With a -40 (4ns) speed rating on it,
the DRAM modules are rated to run up to a maximum speed of 250
MHz! Of course as we have seen past, just because the memory has all the markings of a good overclocker doesn't make it
so. OCZ has been pretty good to us so far though, so we had some
pretty high hopes in store for overclocking this
Everybody loves Overclocking!!!
What review would be complete without an overclocking section? Using the Epox 8RDA+ as the
test motherboard, we lowered
the " Barton core" AMD AthlonXP 3000+'s multiplier to 10x and began raising the
At 173 MHz we ran into a few problems
and had to raise the DIMM voltage to 2.77V to maintain stability. We began to up
the FSB a bit more and at 185 MHz we hit another problem and had to give the
memory module 2.9V to keep the system from BSOD'ing when running PCMark2002.
The highest we were able to push the two
256MB OCZ PC2700 EL sticks of memory while keeping the most aggressive memory
timings was 190 MHz FSB with a DIMM voltage of 2.9V. With more conservative
2.5-3-3-7 timings we were able to hit the 200 MHz FSB mark, but obviously 190
MHz @ 2-2-2-5 is better then 200 MHz FSB with lousy timings.
