"10 Compacs on a single 10 port A-300 hub" - can you run these (all 10) at 325 mhz on that hub?
Probably not.
If memory serves, that guy is 60W...so if running all 10 is the goal, you'd be looking at ~150MHz ea. And, that's only if you can get the Vcore dialed in near just right across all 10.
I think you'd be better of trying to get ~5 running at 250MHz ea. on that hub.
Good luck.
