In operation

Our sample motherboard (Asus P5WD2 Premium) detected the memory without an issue and so we proceeded to perform the benchmarks and stability testing at various combinations of frequency, timings and voltages. During tests involving a high DDR2 voltage of 2.3V and dizzy operational frequencies (900MHz effective or higher), the memory was never overly warm hence there is no need for further cooling through the use of extra fans.

Test setup

Processor: Intel Pentium 4 Extreme Edition 3.46GHz ES (1066MHz FSB, using 12x multiplier)
Operating System: Windows XP Professional SP2 (32 bit)
Memory: 1GB (2 x 512MB) Crucial Ballistix PC2-6400 (default 4-4-4-12 at 2.1V)
Graphics card: BFG Technologies 7800 GTX 256MB, 81.85 version driver
Motherboard: Asus P5WD2 Premium (i955X chipset), 519 BIOS. PCB revision 1.02
Power Supply: Akasa PowerPlus 650W ATX 2.01

Software #1: RightMark Memory Analyzer version 3.6 (to test memory stability)
Software #2: Sisoft Sandra 2005 SP2a (to measure memory bandwidth)
Software #3: Lavalsys Everest Ultimate Edition 2005 version 2.20.405 (to measure memory latency)

Test methodology

Note: Yields of RAM will vary from sample to sample as does motherboard stability at high frequencies, for this reason the results displayed within this review should be used as an indication but not guarantee of the capability of this memory. All tests were performed until a highest stable overclock was achieved. Memory timings were never set higher than the defaults 4-4-4-12 in order sustain an improved level of performance.

Test 1: (stability):

We tested each of the memory configurations up to the highest stable speed and timings using RightMark Memory Analyzer version 3.6. In order for any given memory configuration to classify as stable it had to complete 1 hour of running this software. Unless a given configuration was proved to be 100% stable, tests 1 & 2 below were not executed.

Test 2: (memory bandwidth)

We tested the highest stable speed and timings obtained within test #1 using Sisoftware Sandra 2005 SP2.

Test 3: (memory latency)

We tested the highest stable speed and timings obtained within test #1 using Lavalsys Everest Ultimate Edition 2005 version 2.20.405.
