Hello,

We're somewhat new to building dual processor systems. We have 4 dual processor systems in our office: 3 are Dell PIII and 1 is Athlon MP.

We built the Athlon MP system and performed the single CPU to dual CPU upgrade on two of the Dells ourselves, so we have some experience with building dual CPU systems.

I've looked all over on the AMD FAQ and tech specs for Opterons, but I was unable to answer the following question:

If we buy a single Opteron 244 now and plop it into a motherboard that supports dual cpu, but will run on a single CPU (Tyan S2882UG3NR) will we run into problems later when we add a second Opteron 244 due to differing chip revisions?

The reason I ask is because we had some trouble with upgrading a couple of single Intel PIII systems to dual CPU simply because of the differing stepping levels of CPUs manufactured at different dates.

I need to know if we'll run into similar trouble with the Opterons. If so, I'll just buy both CPUs at the same time, but I'd prefer to save the cash for the moment if I can since we won't need the second CPU for about a year.

Thanks in advance for any info.

No, you shouldn't run into any problems at all. Whatever revisions that may be made will be minor, so you shouldn't have any worries. What would be the point of making a SMP capable processor if the end-user has to worry about compatibility when it comes time to add a 2nd processor?

Exactly. Lets hope the competition doesn't learn this so AMD can continue to dominate this portion of the market.

Thanks for the info.

Like Ardrid said, there really shouldn't be any problems when adding a new processor. You should be able to slap it in and have it recognized and in working order.

But you have to have the same model processor for it to work right? Or not?

Yes, it's recommended that you use the same model. I'm pretty sure that you have to anyway. In any event, there would be no point in going higher or lower because if I'm correct an SMP system works much like a RAID system, it'll default to the lower of the two entities.
