@ 2006/05/22These are also the first kits I know of that support the new EPP enhanced performance extension for the DIMM SPDs, as will most of the overclocker's memory in the future - EPP extends the SPD concept to include extra configuration info for highest-performance settings at higher voltages for automatic top-speed detection by the memory controller.
PC1066 is expected to be the last major DDR2 frequency milestone before DDR3 takes over the performance lead next year. But, is it on any use on the current boards, and how does it compare against its elder brethren? I ran the memory on two boards, one the Intel 975XBX, my standard Presler reference, with 4.26GHz dual-core setup, but limited to DDR2-800 memory speeds - it runs the Corsair 5400UL memory at DDR2-667 CL3-2-2-7 at 1.9 V, a very low latency ideal for in sync work with future Conroe XE 1333MHz FSB; the other one being ASUS P5WD2-E, also a 975X board but with memory overclocking capability to run in DDR2-1066 mode. It also ran Presler XE CPU, but only at 3.73GHz. The 4.26GHz operation was, for some reason, unstable on this board.
