I'm running 242s at present, so they should be fairly similar. |
| 10 |
|
| 11 |
I plan on upgrading to dual-cores later this year or early next, when the |
| 12 |
prices seem to be down to a reasonable level as the new socket format |
| 13 |
takes over, and will run that for another couple years before I even think |
| 14 |
of upgrading mobo/cpu/memory again, at which point I'll have been running |
| 15 |
the same base mobo and platform for over five years(!!), and expect to |
| 16 |
upgrade to a single socket 8-core model as mid-grade. (Of course by then |
| 17 |
AMD's multi-socket co-processor model or a variation thereof may have |
| 18 |
taken the market by storm, and I might as a result be buying a two or more |
| 19 |
socket mobo with one for CPU and the other for GPU, or some such.) |
| 20 |
|
| 21 |
However, the only difference (CFLAGS wise) that I'm aware of for the AMD |
| 22 |
dual-cores is that they now incorporate SSE3, while my old 242s and I |
| 23 |
presume your 246s don't. The other changes I'll be making at the upgrade |
| 24 |
will be in terms of kernel config. Naturally, with dual Opterons, I'm |
| 25 |
already running SMP, but I have it set for two max, and with the |
| 26 |
dual-cores, that will of course change to four. Additionally, there's |
| 27 |
only one level of CPU/core zoning ATM, while there will be two levels |
| 28 |
then, as the pair of cores on the same CPU will cooperate even closer than |
| 29 |
the two in separate sockets but connected by hypertransport bus do. |
| 30 |
|
| 31 |
The big difference in CFLAGS at this point is between Intel and AMD |
| 32 |
products, and since we are both running AMD, that's not an issue. |
