Test Setup

Here you can see the system we tested on.

Test System
CPU:AMD Athlon64 4000+ (S939; 1024KB; SanDiego)
Motherboard:DFI Lanparty nForce4 SLI-D
Memory:2x 512 MB Mushkin Redline XP4000
Video Card:2x Pine XFX 6800 GT SLI @ 450/1200
Harddisk:2x 74GB WD Raptor RAID 0
Power Supply:OCZ ADJ 520W
Software:Windows XP SP2, Forceware 77.60

All parts are selected with high performance and good overclockability in mind to reach high test results. We used BIOS 510-FIX2 (updated version of Mushkin's recommended 510-2) for the DFI LanParty nForce4 SLI-D.

All AlphaTimings in the Bios were set to auto, except for:
  • CPC - Enabled
  • DRAM bank Interleaving - Enabled
  • Idle Cycle Limit - 256
  • Dynamic Counter - Enabled
  • R/W Queue Bypass - 16x
  • Bypass Max - 07x.
  • TRAS - 5
  • TRC - 7
  • TRFC - 14
For JEDEC DDR400A Benchmarks all alpha timings were set to auto.

Very good results, but a motherboard with enough VDIMM is required.
Reduced latencies did not give much overclocking headroom. This shows, that this memory is designed for low latencies. Faster than DDR500 with tight timings is very fast, compared to 2.5-3-3-7.
In the factory, the SPD Timings were not set to the correct values of 2-2-2-5 for DDR500. They were set to 2-3-2-6 for DDR400. Those are the best possible timings for DDR400 using 2.6V. So it's not completely wrong.


265 MHz @ 2-2-2-5 (3.5V)

Benchmarks



For easier comparison with other modules, we set a maximum voltage of 3.1V und tested until we found the highest clock frequency and fastest timings for this memory. The Benchmarks Everest Read, Everest Write and Quake 3 were run. We then calculated the performance increase in percent compared to some standard DDR400 memory running at JEDEC DDR400A (2.5-3-3-8). The average percentage of the three benchmarks is listed in following table:
