I testet one pair of this memory.

On Asus P5B Deluxe (bios 0714) I could run DDR2-964 with 4-4-3-8 and 2.25 volt (stable through superpi 32m).

On Foxconn C51XEM2AA I could run DDR2-1060 with 5-5-5-15 and 2.17 volt or DDR2-908 with 4-4-3-8 and 2.17 volt (stable through memtest).

On AM2-platform I canīt use 1t and/or could get better timings than 4-4-3-5 with 2.17 volt.
