The dual-channel memory format is the standard for high-end performance systems, and is the de facto packaging for most DDR memory. The "matched pair" format has become very popular, as these DDR module kits are perfectly suited for the requirements of high-end dual-channel DDR operation, and are a much safer buy than purchasing one module now and hoping to match it up later. The most popular configurations are currently the 2x512-MB and 2x1-GB kits (although 2x2-GB are emerging) and with few exceptions, vendors offer the same basic speeds in matched pair DDR kits, as with their single module DDR.
The situation was a bit different in the dual-channel DDR chart, and the level of activity increased noticeably. For example, three of the listings showed double-digit shifts, and there were twice the amount of price changes we saw in the single-module DDR chart. Unfortunately, all the significant activity took place at the wrong end of the chart, and $5 cuts to both G.SKILL PC3200 C2.5 2x1-GB and PNY Optima PC3200 2x1-GB kits were the largest in the chart. The trio of double-digit changes were all price increases, as Kingston HyperX PC3200 2x1-GB (+$12), pqi TURBO PC3200 2x1-GB (+$11) and OCZ PC3200 Platinum XTC 2x1-GB (+$10) all helped the chart show an aggregate increase of $32.
