Test Results : Patriot PC3200+XBLK
To be considered stable for test purposes, Quake3 benchmark, UT2003 Demo, Super PI, Aquamark 3, and Comanche 4 had to complete without incident. Any of these, and particularly Super PI, will crash a less-than stable memory configuration.Patriot PC3200+XBLK (DDR400/533) - 2 x 512Mb Double-Bank | |||||||

In rows 1 to 5, CPU speed is kept at 2.4GHZ and only the Memory Speed is varied. The performance differences you see in that range are a result of Memory Speed and memory timings only.
We have looked at Aida 32 results in the past, and found them very useful in examining read/write performance and memory latency. Aida 32 is now available as Everest Home Edition, a free download from www.lavalys.com.

While maintaining a constant CPU Speed of 2.4GHz, we measured the impact of increasing the Memory Speed from 200 to 300, a 50% increase. Memory Read performance increased about 29% with this 50% speed increase, while Memory Write performance improved by just 17%. Latency showed a reduction or speedup of about 12%. With any TCCD memory, Memory Read/Write/Latency benchmarks are also impacted by the slower memory timings required at higher speeds.

Does anyone know of the home page for the company that makes these brainpower pcb's?bupkus - Friday, April 8, 2005 - link
It would seem that at least DFI had planned for it.JoKeRr - Friday, April 8, 2005 - link
first READ!question: running VX continually at 3.3+V, will it damage the memory controller in the long term??
Great review, had a friend with this ram, and it's at DDR600 as well on a A8NSLI DLX.
