Possible to lock a PII 720 down to 2 cores for a better OC?

[Hard and Confused]

Does anyone know if the Phenom II 720 can have yet another core disabled do drop the TDP and hopefully allow a btter OC on the 2 remaining cores? It seems if I could lock down a 2nd core that I should have a low enough TDP with enough of a reduction in heat to easily break 4ghz+ if I only have 2 cores to contend with.

I have a DFI LanParty DK 790GX-M2RS and plan to get a PII 720 in 2 weeks and am just trying to get as much info as I can.

I believe you can do that with the AMD Overdrive utility, assuming your board works with it.

I don't know about locking it down completely but with AMD's Overdrive does something similar

Pretty much on certain programs you can create smart profiles. For those exes you can adjust how the processor works. For example oc certain cores but underclocking the remaining cores.

If you do that you could probably get away with lower voltage but I don't think the you could clock it much higher.

you wont get better overclocking by locking the cores down to 2 cores.. maybe 200 more mhz.. not worth it overall with 2 cores at say 4ghz when you can have 3 cores at 3.6ghz.. do the math.. especially with multi-core applications/games..

and as to date ive yet to see a chip locked to 1 core overclock any better then a chip using 3 cores.. look at most of the record overclocks for the phenom II.. they are overclocking all 4 cores(955BE)..
