G.Skill F1-3200PHU1-512NT 512MB PC3200 / DDR400 Memory Review
The introduction ...
This Review of the G.Skill 512MB PC3200 DDR memory primarily shows if
high-quality memory modules can
reach higher overclocking results and if inexpensive PC-3200 modules satisfy
overclockers even with clearly
more than 200 MHz (DDR400).
Of course two 512 MB modules were tested in dual channel mode and compared
with different timings.
Thanks for the support ...
Many thanks for the support with the F1-3200PHU1-512NT 512MB PC3200
modules by the manufacturer G.Skill
One G.Skill F1-3200PHU1-512NT 512MB memory module has a current price
of 45 Euro (07/2006) and
is of course also available at our sponsors.
In this Review are used two G.Skill 512MB modules.
The supply of the 512MB PC3200 memory modules ...
In these plastic packages are the well protected memory
That is contained in the scope of delivery ...
G.Skill doesn't deliver the memory modules with any manual
(like e.g. Crucial), but there're a few tips on
the package how to handle them carefully.
Here's a picture of the unwrapped modules:

Benchmark values and test results ...
Let us begin with the maximum timings and the benchmark
ratings on different frequencies.
The test results are based on an EPoX 9NPA+ SLI nForce4 Motherboard with
an Athlon 64 3000+ CPU
running with a different frequency depending upon reference clock for
the different memory benchmarks.
Thus the multiplicator adjustment remains on 9x with all frequencies.
An adjustment for the CPU in half steps would be too inaccurate to get
nearly the same CPU frequency for all tests.
Microsoft Windows XP Professional SP2 is used as operating
The stability was examined with the software Memtest86
and the SiSoft Sandra
Lite 2005.SR3 program is used
for all benchmarks, since it offers extensive adjustments and a fast result
First the maximum possible frequency of the memory modules
was determined in dual channel mode.
Therfor the memory frequency was increased in small steps with a fixed
memory timing of 2.5-3-3-8 (2T) and
default memory voltage, as long as the detailed memory test with Memtest86
runs without errors.
This quite long testing time ensures that this frequency works really
stable on these modules.
The highest possible frequency with 2.5-3-3-8 (Tcl Trcd
Tras Trp) values was stable with 235 MHz.
For example, the Crucial
Ballistix Tracer PC4000 modules reached with the same timings up to
With increased voltages or lower timings it's possible to run clearly
higher frequencies, because the
frequency values and timings depends directly from each other.
This highest possible frequency was compared to two adjustments.
On the one hand 235 MHz with SPD values (these are given by the manufacturer
in the SPD IC) and on the
other hand 200 MHz with SPD values.
By the way, the "Memory Bus Range" is no benchmark value, but
the value is quite simple to calculate by the
frequency and is useful for the benchmark comparison.
Here're the benchmark results:
RAM Range Int Buff'd iSSE2
Memory Bus Range
fix (2.5-3-3-8 2T)
SPD (3.0-5-5-9 2T)
SPD (2.5-4-4-8 2T)
And here's a diagram of the benchmark values:
The result is quite good for PC3200 memory modules.
However, 235 MHz may be already insufficient to overclock processors with
locked multiplier and it would be
necessary to reduce the timings at the expense of performance to reach
To overclock newer AMD Socket A processors, AMD Athlon 64, or Intel CPUs
with fixed multi (see workshop
it's recommendable to use faster memory modules.
But without overclocking, the choice of PC3200 DDR modules is still resonable,
because there's nearly no noticeable
difference compared to High-End PC4000 modules running with 200MHz (internal
400MHz) and SPD autodetection.
Result and general impression ...
The G.Skill F1-3200PHU1-512NT 512MB memory modules are
resonably priced and offers good overclocking
results for PC3200 modules.
But high-end overclocker should pay a little bit more, to get more scope
for better timings at higher frequencies.
