Re: How can an on die memory controller be crippled by the MB?

Bad BIOS settings, for one. Also, QPI is a high bit-rate protocol. Retries in the protocol due to single bit errors on a badly laid out motherboard can slow down performance as well. Lastly, the CPU itself is an early pre-production stepping.

You can connect the dots, Pete. Anand's review is pretty clear that the newer boards greatly improve the memory performance.

Re: Which would mean they still have issues and need to respin again. Besides if the samples were that bad, imagine how poor the yields must be.

No kidding, Pete? Pre-production silicon might need a respin...?

Intel is doooooommmmeeedd!

You expect A2 silicon to be perfect?

Besides if the samples were that bad, imagine how poor the yields must be.

Why would early silicon have any impact on yield? 45nm is reaching maturity and defect density is already world class if Intel's claims are true. Please explain why DD would be any different for Nehalem than it would be for Penryn.
