The i7-920 cannot run memory at anything faster than DDR3-1066 speed with the CPU running at stock speed. That CPU must be overclocked in order to run memory at even DDR3-1333, let alone DDR3-1600, speed. |

Alright, I am trying to clear up some of the misconceptions made by myself and others:
It is true that the X58/ICH10R combo has a total of 36 PCI-e 2.0 lanes plus six PCI-e 1.0 lanes. It is also true that the P55 has eight PCI-e 2.0 lanes that are restricted to PCI-e 1.0 bandwidth - in addition to the 16 PCI-e lanes on the 1156 CPU's die. And I was wrong about the PCI-e 2.0 lanes being graphics-only. They can be used by any device. With 36 available PCI-e 2.0 lanes, any USB 3.0 and SATA 6 Gbps controllers on an X58 motherboard will still allow you to have one or two graphics cards running at the full PCI-e 2.0 x16 bandwidth without the need for a safety mode. The 1156 CPU has only 16 full-bandwidth PCI-e 2.0 lanes, forcing the need for a Safety Mode on the controllers which "steals" four of the eight bandwidth-restricted lanes on the P55's PCH (or a PCI-e bridge chip that provides four additional PCI-e 2.0 lanes) and a Turbo Mode which restricts the main 1156 CPU's PCI-e lanes to eight available lanes. |

After 10 weeks from last post it seems funny that this particular thread has been resurrected. The platforms each have their advantages. The practical differences are so slight they are almost not even worth a debate, IMO.
However, in this case the debate is between a person and themselves, which I suppose is interesting enough by itself. |
