OCZ 2x1GB PC2-6400 DDR-2 SLi Ready Memory Review

OCZ is a respected memory manufacturer that markets most of their memory modules towards computer enthusiasts looking for high performance memory. Today, we look at their midrange PC6400 / DDR2-800 memory.  This particular model comes with 2GB (Dual Channel) of total memory, each stick offering 1GB.  This model is also SLi ready, meaning that it has the EPP profile that works well with nVIDIA SLi based motherboards.  The timings are great at stock speeds (4-4-4-15 @ 1T).

The short manual offers enough information to install these modules properly.

Here are some of the main features and specifications from OCZ's website

The Memory:

The memory's external appearance looks great, with its heat spreaders.  The heat spreaders are exclusive nVIDIA XTC heat spreaders, which dissipate heat efficiently and looks great at the same time. 

This image shows both sides of the modules, each side showing that these two modules are SLi ready. 

Removing the heat sink shows that the memory chips are OCZ branded.

Testing:

For this memory, the test system consists of the following:

-Antec Nine Hundred Case

-Seasonic M12 600 Watt Power Supply

-Intel Core 2 Duo E6420 Dual Core Processor @ 3.2 GHz

-ZeroTherm BTF90 Heatsink

-eVGA nForce 680i LT SLi Motherboard

-2GB (1GB x 2) of OCZ PC2-6400 DDRII-800 Memory

-320GB x 4 Western Digital 16MB Cache Hard Drives

-2x nVIDIA GeForce 8800GTS Video Cards @ 625MHz Core / 1000 MHz Memory

-Sound Blaster Live! 5.1 Digital Sound Card

-Sony 16x DVD-RAM / 18x Samsung DVD-RAM Drives

-4x 120MM fans, 1x 200mm fan

-2x CCFL Lights

*Overclocked, the modules were running at 2.2 Volts

The first test was to run using Lavalys' Everest 3.5, memory read.  The results of this memory is great and was even better when it was overclocked.  The 1T timing could not be used when overclocking, so I changed it to 2T.  The timings were also changed to 5-5-5-18 in order to overclock.  I could get a maximum of 500MHz/1000MHz DDR before it got unstable.

The memory writes also increased with the overclock, using the slower timings.

The stock memory timings produced a lower latency in this case

In SuperPi XS 1.5, it can be seen that the overclocking has also helped the calculation time on the SuperPi program.

The results were great for this dual channel set of memory, offering a decent amount of overclocking headroom.  I also found that the default EPP timings were discovered by my testing motherboard, which is great, since you are getting the best timings right out of the box.  The default timings were 4-4-4-15 @ 1T and overclocking forced me to put it at 5-5-5-18 @ 2T.  The overclocked results are great as well, offering a noticle performance boost in the benchmark results, with a slight increase in latency. It can be found in online shops for around ~$100.

Pros +

-Great Stock and Overclocked Performance

-Lifetime Warranty

-nVIDIA SLi Ready

-nVIDIA Heat Spreaders

-Good Value

Cons -

-None
