Crucial 10th Anniversary 2GB Kit (2x1024MB) PC2-5300/DDR2-667 Memory Review


The introduction ...

The company Crucial should be well known by everyone who is interested in PC or Macintosh hardware and
already acquired some memory modules.
It's not only because of the high performance of the modules, but also because of the long existence of the company.
Crucial recently became 10 years old and they celebrated their 10th anniversary with special chocolate modules
(yes, memory modules can be tasty) and with special 10th Anniversary 1GB PC2-5300/DDR2-667 CL3 memory modules.
PC2-5300 does not sound very fast, but sometimes the test results differs from the first impression.

If you like to know more about the 10 years Crucial, you should take the time for their interactive Flash animation.



Thanks for the support ...

Many thanks for the support with the TY2KIT12864AA663 tenth Anniversary 2GB PC2-5300/DDR2-667 CL3 kit by Crucial.

The 2 GB kit contains two 1024 MB 10th Anniversary 240-pin DIMM DDR2-667 memory modules and
the current price is about 298 euro (11/2006).
They're available with the upper banner in the Crucial Shop and at our sponsors.



The supply of the two 1024MB PC2-5300 memory modules ...

In this small box are the two very well protected memory modules:



That is contained in the scope of delivery ...

Crucial supplies the two memory modules as well as a multilingual installation guide, which should make it possible
also for less experienced users to install them easily:

Characteristics and other features ...

The memory modules are provided on a black plate with an embossed silver logo on the blue aluminium passive heatsinks
(heatspreader) which are supposed to enhance the memory cooling also with higher frequencies and/or higher voltages.
Thus one achieves on the one hand better results with overclocking and on the other hand a longer life-time,
whereby Crucial by the way grants lifelong warranty (Limited Lifetime Warranty) for the buyer
(all informations to manufacturer conditions are of course without guarantee by

Benchmark values and test results ...

Let us begin with the most important part of the test report, because the optics is of course rather secondary and
the possible stable performance is the most important factor.
The test results are based on an ASRock AM2XLI eSATA2 SLI motherboard with an Athlon 64 Socket AM2 3000+
CPU on different frequencies depending on the reference clock for the different memory benchmarks.
Thus the multiplier adjustment remains on 9x with all frequencies, because an adjustment for the CPU in half multiplier
steps would be too inaccurate to get nearly the same CPU frequency for all tests.

Microsoft Windows XP Professional SP2 is used as operating system.
The stability was examined with the software Memtest86 and SiSoft Sandra Lite 2007.SP1 program is used for all
benchmarks, since it offers extensive adjustments and a fast result comparison.

First the maximum possible frequency of the memory module was determined.
The memory frequency was increased in small steps with a fixed memory timing of 4-4-4-10 2T and default memory voltage, as long as the detailed memory test with Memtest86 runs without any errors.
This quite long testing time ensured that this frequency works really stable with these modules.

The highest possible frequency with 4-4-4-10 (Tcl Trcd Tras Trp) timings was stable with amazing 451 MHz !

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 443 MHz with SPD values (these are given by the manufacturer in the SPD IC),
and on the other hand 200 MHz (x2) with SPD values.
Unfortunately the two modules could not be used with the highest possible frequency of 451 MHz with SPD values,
since those SPD EEPROM Timings were too fast with this very high frequency.
To that extent this benchmark value remains unfortunately empty.

By the way, the "Memory Bus Range" is no benchmark value, but this 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
451 MHz
fest (4-4-4-10 2T)
6309 MB/s
14432 MB/s
451 MHz
SPD (noboot)
200 MHz
SPD (4-3-3-9 2T)
4651 MB/s
6432 MB/s


Here's a diagram of the benchmark values:


Here is a direct benchmark result comparison of some DDR2 and DDR memory modules:


The result of the Crucial PC2-5300 CL3 memory is extraordinarily good, because in the direct compare to the
previously tested PC2-6400 CL4 modules they're clearly faster.
Despite lower frequency (PC2-5300 to PC2-6400) the modules achieve higher overclocking results due to the faster latency timings (CL3 to CL4).


Result and general impression ...

The Crucial 10th Anniversary 2GB PC2-5300 CL3 kit (TY2KIT12864AA663) is better overclockable than the PC2-6400 CL4
pendant and they are thereby very useful for a very high FSB and/or reference clock.
High-End overclocker should not only pay attention to the highest speed, but like always on the best combination of frequency and Timings.
10 years Crucial were in any case worthwhile.
