Corsair PC2-6400C4

1. Introduction

Corsair is one of the best known memory manufacturers. Corsair has been producing products for all categories of users, from entry level to enthusiast. Today we will test an entry level DDR2 memory product that while keeping its retail price very low, is able to be provide much higher performance than you might have expected.

- Corsair PC2-6400C4 v2.1 Edition

The Twin2X1024-6400C4 is a 1GByte matched pair of DDR2 SDRAM DIMMs. They delivers outstanding performance in the latest generation of dual-channel DDR2-based motherboards and have been tested extensively on multiple DDR2 motherboards to ensure compatibility and performance at their rated speed. This memory has been verified to operate at 800MHz at the low latencies of 4-4-4-12. The Twin2X1024-6400C4 come with Enhanced Performance Profiles (EPP), the open standard for performance module SPDs jointly developed by Corsair and NVIDIA. EPP SPDs on Corsair modules allow users to automatically configure EPP enabled motherboards with aggressive memory performance settings, for maximum memory and system performance.

- Features

  • 1024 Megabytes of DDR2 memory
  • SPD includes Enhanced Performance Profiles (EPP) which automatically overclock to aggressive performance settings
  • Implemented using 64Mx8 DDR2 SDRAMS

  • Tested and packaged in pairs
  • Tested at EPP SPD settings (4-4-4-12) at 2.1V
  • SPD programmed at:

    • EPP standard 4-4-4-12-2T, 2.1V values at 800MH

- Retail package

Corsair provided us with the retail package of the XMS2 6400C4 with 2 GB (2x1GB), that cost around €150~190 (+shipping) as found at several online stores. The kit comes in the standard packaging for Corsair memory products.

After opening the retail package, we examined the modules more closely. On both sides there is the Corsair Logo, while on one side there are the product specs:

Let's zoom in on the product specs. We can see a variety of formation, like the full product code, revision (v2.1) and timings.

There are several revisions of 6400C4. If the revision is v1.x it should be based on Micron's D9 chips, a superb product for overclocking. While, if it's 2.x, it's probably Promos. If the revision is 5.x or 6.x, it's probably based on Infineon chipsets. More information about this topic can be found here.
