I'm running 242s at present, so they should be fairly similar. I plan on upgrading to dual-cores later this year or early next, when the prices seem to be down to a reasonable level as the new socket format takes over, and will run that for another couple years before I even think of upgrading mobo/cpu/memory again, at which point I'll have been running the same base mobo and platform for over five years(!!), and expect to upgrade to a single socket 8-core model as mid-grade. (Of course by then AMD's multi-socket co-processor model or a variation thereof may have taken the market by storm, and I might as a result be buying a two or more socket mobo with one for CPU and the other for GPU, or some such.) However, the only difference (CFLAGS wise) that I'm aware of for the AMD dual-cores is that they now incorporate SSE3, while my old 242s and I presume your 246s don't. The other changes I'll be making at the upgrade will be in terms of kernel config. Naturally, with dual Opterons, I'm already running SMP, but I have it set for two max, and with the dual-cores, that will of course change to four. Additionally, there's only one level of CPU/core zoning ATM, while there will be two levels then, as the pair of cores on the same CPU will cooperate even closer than the two in separate sockets but connected by hypertransport bus do. The big difference in CFLAGS at this point is between Intel and AMD products, and since we are both running AMD, that's not an issue. -- Duncan - List replies preferred. No HTML msgs.
