Max QPI is based on what?

508 Views 1 Reply 2 Participants Last post by  Blameless
I've seen 4.8 and 6.4 GT/s QPI speeds. Is the max speed based on the CPU, or the chipset/mobo? My mobo supports 6.4 GT/s; do I need one of the intel 975 EE to run QPI at that speed or can my i7 920 handle it?

The rated speed is a function of the CPU.

The max stable speed on most X58 setups is around 8GT/s, regardless of CPU.
