Corsair showed us its latest achievement in memory speeds - we witnessed a pair of 1GB modules of DDR2 memory running at over 1250MHz with 5.0-5-5-18-2T timings on ASUS' M2N32-SLI Deluxe motherboard paired with an Athlon 64 FX-62 running at over 3.1GHz with Corsair's own Nautilus watercooler.
In order to achieve such clocks, it had to redesign the PCB, to allow for better cooling. There are a limited number of AM2 processors capable of such high memory speeds and Corsair themselves said that this was the only chip capable of such high memory frequencies. As many will know, AMD's latest chips have an embedded DDR2 memory controller, allowing for minimal latency when running at high memory bus speeds.
We managed to get an Everest readout from the chips, giving an idea of how these modules perform at such high speeds. Read speeds were in excess of 10000MB/sec, while write speeds approached 9000MB/sec. Memory latency was down to an incredible 36.7ns - that's considerably lower than our own measurements, which indicate that FX-62's memory controller has a latency of around 75ns according to the SiSoft Sandra 2007 memory latency test.

We spoke to a Corsair representative, who said that the company expects to ship these modules at some point in the near future. However, it is worth noting that you'll need a CPU capable of coping with high memory controller frequencies. We'll leave you with a few more pictures...
