Performance Test ConfigurationThe Mushkin Redline XP4000 was tested with the DFI LANParty nF4 SLI-DR Athlon 64 Socket 939 motherboard. The DFI nForce4 SLI and Ultra are the only current production boards that support the 3.3V to 3.5V rated voltages required for Redline DDR500 performance. An OCZ DDR Booster can be used with motherboards without support for high memory voltages. Other components remain the same as used in the memory setup in Athlon 64 Memory: Rewriting the Rules.
The A64 test bed includes components that have been proven in Socket 939 Athlon 64 benchmarking, such as the Socket 939 4000+, and the OCZ Power Stream 520 Power Supply. Since the Athlon 64 tests represent a new series of DDR testing, we have chosen the current generation NVIDIA 6800 Ultra video card for benchmarking. We have found the 6800 Ultra to be a particularly good performance match to NVIDIA motherboards.
All other basic test conditions attempted to mirror those used in our earlier Intel memory reviews. However, test results are not directly comparable to tests performed on the Intel test bed.

In past benchmarking, we have found performance of the nForce4 and nForce3 chipsets to be virtually identical, and we have found AGP and PCIe performance to be virtually the same in the benchmarks that we use for memory testing. Therefore, you can also generally compare these results to TCCD benchmarks in recent memory reviews.
With nForce3 motherboards, the fastest performance on AMD Athlon 64 was at a Cycle Time or tRAS of 10. However, the nForce4 behave a bit differently with memory. We ran a complete set of Memtest86 benchmarks with only tRAS varied to determine the best tRAS setting for these memories, and found the best bandwidth at tRAS settings ranging from 5 to 8. Therefore, a tRAS setting of 6 was used for testing.
Test SettingsAll AMD Athlon 64 processors are unlocked downward, and the FX CPUs are unlocked up and down. This feature allows a different approach to memory testing, which truly measures performance differences in memory speed alone. All tests were run with CPU speed as close to the specified 2.4GHz of the 4000+/FX53 as possible, with CPU speed/Memory Speed increased at lower multipliers to achieve 2.4Ghz. This approach allows the true measurement of the impact of higher memory speed and timings on performance, since CPU speed is fixed, thereby removing CPU speed as a factor in memory performance.
The following settings were tested with the Mushkin Redline XP4000 on the DFI nF4 test bed:
- 2.4GHz-12x200/DDR400 - the highest stock memory speed supported on VIA 939/nF3-4/SiS755-FX motherboards
- 2.4GHz-11x218/DDR436 - a ratio near the standard DDR433 speed
- 2.4GHz-10x240/DDR480 - a ratio near the standard rating of DDR466
- 2.4GHz -9x267/DDR533 - a memory speed achieved by only a few top memories on the Athlon 64
- Highest Memory Performance - the highest memory bandwidth and game performance that we could achieve with the memory being tested; this is rarely the highest memory speed that we could achieve. It is normally a lower speed with 1T Command Rate and tighter memory timings.
We ran our standard suite of memory performance benchmarks: Quake 3, Return to Castle Wolfenstein-Enemy Territory-Radar, Super Pi 2M, and Sandra 2004 Standard and UnBuffered. We also included Everest Home Edition memory tests, free at www.lavalys.com, for read speed, write speed, and Latency.
