- Low Latency Modules Surface
AMD users in particular will be glad to know Corsair have announced a new range of "XL" memory modules which run at their rated speed (400mhz) with ultra low latencies of 2-2-2-5. 2x512 TwinX products under the XL name come in three different flavours, the "XMS Pro Series", "standard black XMS", and "platinum XMS". Corsair have even fiddled with higher latencies knowing there's sure to be quite a lot of overclocking headroom on these (refer to comments below).
In addition to 2-2-2-5 performance at PC3200, the 3200XL family demonstrates excellent performance at higher clock frequencies. Typical results seen in the Corsair lab were 2.5-3-3-7 at XMS4000 (250 MHz) clock speeds.
These modules were designed specifically to give plenty of overclocking headroom for performance tweakers. At slightly higher latencies these modules can yield stable operation at speeds up to 500MHz. Corsair designed these modules with the unique ability to function both at 400MHz with extremely low latencies, and at very high clock speeds with looser latencies.
If interested, you can grab the spec sheets for both the single 512mb XL and TwinX 1024 XL modules. LegitReviews have already been fortunate enough to get their hands on some sticks and although the final review isn't completed yet, they've kindly posted up their first benchmarks and images for us.
Funnily (but not surprisingly) enough, OCZ Technology have also announced a similar range of modules, dubbed the "PC-3200 Platinum Rev 2 Dual Channel kit", operating at latencies of 2-2-2-8. More details on these within the press release over at their website.
"The trend has been to move to higher frequencies at the expense of latencies" said Dr. Michael Schuette, director of technology development at OCZ Technology. "However, given the fact that in most architectures the host bus cannot handle the Memory bandwidth, we need to refocus on what the real needs are. Seamless data flow can only be achieved in a low latency environment. This is where OCZ Technology, once again, takes a leading role in the industry".
