Test Setup & Methodology
After my previous reviews, using 2x 1Gb modules, and looking for the compatibility issues I had with my barebone system, the thing that caught my eye, was a performance drop of 1-5% when using switching to 2x1Gb compared to 2x512Mb. Odd fact was, that Memtest86 mentioned a higher bandwidth for 2x 1Gb than the 2x 512Mb modules.
The larger modules showed a disadvantage using my old faithful DFI NF4-Ultra-D, and RDX200 CF-DR when using exactly the same timings in the same benchmarks, as long they don`t need more than 1Gb.
After talking to some technicians from DFI at Cebit, they confirmed this, although an explanation on this phenomenon was not given other than it having something to do with optimization issues. They told me they were working on a new bios, which will remove this last hurdle and make their boards fully optimized for both 2x 512Mb and 2x 1Gb modules.
Their latest motherboard, the CFX3200-DR, will be the base for this review as it is fully optimized for both using 2x 512Mb and 2x 1Gb modules. I used bios revision R5D-043C, as it was the only one which could run all modules without issues. Switching out my SATA Maxtor for a PATA model allowed for ~15Mhz increase in FSB.
