After playing with my X6800, I decided to change my benching cpu, and got my hands on a Kentsfield 2.66GHz, as everybody know here, it's a quadcore (two conroe E6700 dies on the same package), so 2.66 / 8M /1066 to use the usual intel notation.
The only working (and with overclocking abilities) motherboard I have for now is an unmodded Intel D975XBX rev304, with the last official bios. Kenstfield is not officially supported (scheduled for Q1'07, so nothing weird here...) and the fsb crashes above ~270-275MHz. Fortunately my sample is fully unlocked, from 6x to ... i've tried 16x for now, and it works well, it seems that it's like the X6800 on this point.
