Opteron 200-series can only be used in 2-socket motherboards. With dual-core CPUs, this gives you 4 CPU cores to use. Opteron 800-series can be used in 4-socket motherboards. With dual-core CPUs, this gives you 8 CPU cores to use. Both of the above are based on the same CPU architecture, and use the same RAM -- DDR-333 or DDR-400. The newer Opterons (1000-, 2000-, 8000-series) use DDR2-533, DDR2-667, or DDR2-800 RAM. So you can't use your RAM in newer motherboards with newer Opterons. Intel Xeon processors use FB-DIMM RAM, so you can't use your RAM with those. These can be used in 2-socket or 4-socket motherboards, with up to 4-cores per socket. These are also very expensive, run very hot, and require very specific chipsets and motherboards. Depending on the workload and RAM requirements, these are either a lot faster than Opterons or a lot slower. Intel Core2 processors use DDR2 RAM and only on 1-socket motherboards. The only way to save parts would be to get a 4-socket motherboard and AMD Opteron 800-series PCUs. Then you could re-use your RAM. Otherwise, you have to get new CPUs, new RAM, and a new motherboard. -- Freddie Cash [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
