If you remember, in the temporary forum I presented to you my new cruncher :
Dual Xeon Quad Core 5410. These are 45nm Pernryns with a FSB @ 1333Mhz (333x4).
My mobo (Asus DSEB-DG - chipset 5400) supports a 1600 FSB.
And a very easy pin mod make the motherboard detect the chip as 1600FSB CPU.
It' now running @ 2.8 Ghz .
