Now that AMD and Intel are both using unbuffered non-ECC DDR2 memory for mainstream products, our focus has shifted to testing high-performance DDR2 memory.

More and more enthusiasts opting are for 2 GB of RAM, especially now that many games require at least this much to run without a hitch. Keeping in mind that it is harder to get larger sized memory modules to be stable with lower timings, it's no wonder that memory module manufacturers are eager to release high-capacity 1 GB sticks with timings that will appeal to enthusiasts and gamers.

Today we are looking at Super Talent's 2 GB low-latency PC2-6400 dual channel kit. The T800UX2GC4 is rated to run at a very impressive 4-4-3-8 timings at an 800 MHz clock speed - which is pretty impressive as most other "low latency" PC2-6400 modules run at 4-4-4-12!

Our modules have a sliver finish, unlike the blue finish listed on their data sheet - however the modules have the same part number.

Kit Features:

• Two 240-pin DDR2 DIMMs
• Non-ECC, unbuffered
• 4-4-3-8 timings at DDR2-800
• Cast aliminum high efficiency heat spreader
• SPD programmed to DDR2-667 with 5-5-5-15 timings
• Lifetime Warranty

In recent DDR2 memory module reviews we found overclocking headroom to be excellent. For this review we decided to approach the memory from two different perspectives: take a look at the performance of the stock setup with the excellent timings, and then see how far we could really push the memory.

Software used during testing consisted of the following:

• Windows XP Professional with Service Pack 2
• NVIDIA ForceWare 84.21 drivers
• RightMark Memory Analyzer
• SiSoft Sandra
• WinRAR
• Doom 3

Hardware:

• Pentium D 930 3.0 GHz 2x 2 MB L2 cache processor
• Intel Pentium D 840 3.2 GHz 2x 1MB L2 cache processor
• ASUS P5WD2-Extreme motherboard
• 2 * 1 GB Super Talent PC6400 low latency memory
• 2 * 1 GB Crucial Ballistix PC6400
• 2 * 512 MBCorsair XMS2 PC8500 (we have also have a review of the 2x1GB XMS2 PC8500)
• XFX GeForce 7800 GT

We are presenting you with a FULL set of overclocked benchmarks - our test systems were all stable at the settings shown with air cooling. Please note that chart labels incorporate a lot of information about the test configuration. The first line shows the socket type and the model of the processor. Since all the processors shown are dual core devices, we did not specify that on the charts.

The second line shows the "FSB/HT clock rate" x "CPU multiplier" followed by the effective DDR memory speed.

The Questions:

1. "Do these modules meet their specifications?"

2. "Can we exceed the manufacturer's specifications?"

Let's find out....
