CPU stepping on a dual Xeon Nehalem Server build

HI

What do I need to know about dual Xeon 1366 Nehalem builds before I go and lay out for 2 of CPUs. Is stepping an issue I need to be aware of, or can I simply dunk two of the same CPUs on to a board? I haven't been able to find any good resources online about it, but if you have a link or experience of the same I'd like to hear about it.

Thanks

According to http://www.intel.com/Assets/PDF/specupdate/321324.pdf the only stepping is D-0 which is hardly surprising since they've only just been released publically. To check whether there is more than one stepping of a CPU you can check the spec updates at http://www.intel.com/p/en_US/products/server/processor/xeon5000/technical-documents

Does that mean ... I can pop 2 x D-0 CPUs in one board and there wouldn't (in theory) be a problem? Or would I need e.g. D-0 primary slot and D-1 secondary slot? I've never built a dual CPU system before and need to be certain.

Steppings should match so two D-0 stepping CPUs will be fine. Don't forget to balance the RAM across the pair of CPUs, memory population can be quite complicated but your motherboard manual probably has the recommended population order. ach CPU has 3 memory busses so we count RAM in 3s and 6s now.

Good stuff, thanks, I'm about to click "Buy" at a parts retailer in an attempt to save a thousand pounds, and gain some processing power to boot
