I have a bunch of PowerEdge 2650's, most of them running at 2.4Ghz or less. I'd like to upgrade them to 3.06 and 3.20 GHz Xeons (at 533MHz FSB). HOwever, I notice that the 3.06 CPU's come with both 512KB L2 cache and 1MB L2 cache. all my boxes have 512KB cache. can i use the 1MB L2 cache chips in the 2650? It would seem that this wouldn't be a problem, but I had an issue with my 4350's, many years ago, not being able to run faster than 600MHz P3's because of a different cache size in the P3's between 650 and 1100. (my 4300's could go up to 1000MHz P3's without any problem). Hence the quandry - will a Xeon with 1MB of L2 cache work okay in a 2650 (dual proc)?
