Just got my Winchester 3200+, with a GA-K8NSNXP-939, 4x512mb of Micron ram, and waiting on my BFG 6800GT OC.
Experimenting with the Winchester, as soon as computer booted, Dram ratio to CPU/12(166), cranked FSB to 250, HT multiplier down to 4x, Vdimm raised to 2.7, Commandrate 2T, No Vcore change. Save/exit, BOOTED!! and Superpi stable! 35 seconds for 1mb calculation. The new Winchesters does seem a bit warmer compare to the older Newcastle/Clawhammer chips.
I pushed Vcore a little higher, 1.5V, got to 2600mhz stable, 1.55 didn't help, 1.6 didn't do much either, finally 1.65 got me to 2700mhz. Somewhat stable, superpi stable, but not prime95 stable. Oh BTW 32 seconds for 1mb pi.
It seems these Winchester chips all do 2.5Ghz without any problem, you may need 1.5Vcore, anything higher doesn't do much.
The new chips seems to run a little warmer, if your load temps goes into the 50's you shouldn't be worried.
When i'm doing non-demanding apps, i only need about 1000mhz, so using clockgen, i downclocked the multiplier to 4x, using 250FSB, gives exact 1000mhz, i wanted to see how low i could push the voltage, and lowest i got that prime stable at 1000mhz is 0.825Vcore. At this Vcore it lowered my idle temp down to 26C and load to 32C. For people who has patience to use clockgen's ghost format to switch speed around to save power and reduce heat this info might be a little helpful. When you downclock to 1000mhz, try 0.900 first, then go lower bit by bit.
