With the maturity of a market space, comes the increasing desire
to push the envelope. This is true no matter what sector of technology
you focus on. Apparently, DDR2 (or PC2) memory has reached a maturity
level that is allowing memory manufacturers to tweak more performance
out of them.
Case
in point, not long ago, a 2GB kit (2x1GB modules) of memory was
lacking in performance when compared to a 1GB kit (2x512MB modules).
The timings on such size of memory just could not match those
of its lesser sibling. I am going to be putting a pair of newly
acquired 1GB DDR2 modules through several tests.
SuperTalent
has provided VL with a pair of 1GB modules paced at PC2-6400,
a quick glance at the specifications and you quickly realize
these aren't your 1GB modules from yesterday, so lets look over
the specifications to see where they are pushing it.
In
the PC2 arena, these are some pretty tight timings, add to that
the simple fact these are 1GB modules.

SuperTalent
is a relative unknown in the enthusiast arena, formed just over
3 years ago from MaLabs (20+ years as an unbranded memory manufacturer)
with a focus on the memory/flash market. SuperTalent uses MaLabs
as their main distributor and enjoys a large facility in the San
Jose area, where they maintain strict quality control. Their memory
modules come with the defacto standard lifetime warranty, however
further information abut the modules is not readily available,
something that needs to be addressed on their website and the
packaging.
The
modules arrive with Aluminum Heat Spreaders, peaking inside was
not possible as whatever superglue they used, I was unable to
pry off without crossing that “safe pull apart” barrier,
so I trusted my research (oh, and the guys at SuperTalent who
responded to my email) that these are in fact the new Micron 2.5ns
DDR chips. DDR-II memory is identified using PC2 instead of just
PC in its speed rating. The SuperTalent modules I am testing today
are PC2-6400, you can take this as being equal to 800MHz (although,
once again the guys at SuperTalent had claims of 889MHz on their
test bed).
Unfortunately,
AMD has yet to release the M2 so I am forced to test these on
only an Intel based system. For comparison, I will be sampling
previously tested OCZ 1GB kit (2x512MB PC2-5400) at stock speeds,
yes I know its not exactly fair, but I want to see (and don't
you) how far these 1GB modules have come.
Test
System - Asus
P5WD2-E, HIS
Radeon X850XT IceQ II, WD
250GB 7200RPM SATA-II, Intel
640 (P4 3.2 EM64T LGA-775), Asus A55G 550W PSU
Memory
- SuperTalent (1.8V) (4-3-4-8), OCZ
EB Platinum Edition (2.1V) (4-2-2-8)
When
you set them next to each other (the CL values) you can see some
advantages going to OCZ, we will see if this plays out
through the testing phase.
Test
Suite
SiSoft
Sandra 2005.SR2 - Although
a synthetic benchmark, it's a popular one, freely available if
you wish to make comparison benchmarks. We will be testing the
memory speeds at stock 3.2GHz speeds as well as 4.0GHz OC'd
PiFast
- A
good indicator of CPU/Motherboard performance is PiFast
version 4.3, by Xavier Gourdon. We used a computation of 10000000
digits of Pi, Chudnovsky method, 1024 K FFT, and no disk memory.
Note that lower scores are better, and times are in seconds.
TMPGenc
Plus 2.5 - Video
encoding is a taxing chore, both on Memory and Processor, we will
be encoding a 150mb AVI file to MPEG2. For the AVI to MPEG2 I
used a bit rate of 5000k/Sec, as this is the midrange for a DVD,
which is typically between 1000k/Sec to 10,000k/Sec. I used a
frame size of 720x480 (DVD Std) and 16:9 NTSC. Note that lower
scores are better.
Quake
4 - Although
memory plays a role in game performance this was not the crux
of this test scenario. I wanted to see if a current game would
benefit from the extra memory, seeing as Quake4 appears to have
fixed their demo program, it had to be my game of choice for this
measurement.
SiSoft
Sandra 2005

The
results surprised me here, even with this being a synthetic benchmark,
SuperTalent performed much better then I would have anticipated
a 2GB memory kit to perform and in the end, outperformed OCZ.
PiFast

While it is close, SuperTalent does slightly outperform OCZ. I
know some of you are thinking, how is SuperTalent outperforming
OCZ when the timings on the OCZ modules are tighter? Maybe there
is a little something to this 2GB kit thing after all.
