I do assume the 720 would work as well.
You can try, but like gurusan said in another thread.

Fair enough. I'm still debating getting the X3 anyway, especially since the 7750 went down to almost 60 bucks. It's so tempting for the cost.

Yesterday, a user posted an interesting piece of discovery in our forums and that had prompted enthusiasts to try for themselves. Till now, several users have reported success with the unlocking of the Phenom II X3 processors. To verify those claims, board makers too had done some internal testings and so far achieve some success as well. Above is test done on the DFI 790FX board and similar success stories are reported from the labs from Biostar, Gigabyte and others as well.

From what we know, only 0904 batches of Phenom II X3 can be unlocked. Basically, it just uses ACC core to trick the CPU to enable 4th core that has been classed unstable by AMD. However, not all unlocked Phenom II X3 will be stable so you will need some luck here.

Phenom II X3 processors are selling in the States for US$150 and if you wish to get locally in Singapore, the only place you can find them are in Cybermind, retailing for S$246. Last checked their batch is 0904BPMW.

Board Makers Confirmed Phenom II X3 Unlocking - News and Reviews

The success of this mod however, depends on a few factors:

* The disabled core AMD notes to be "unstable", should be fit-enough to be at least enabled and working
* The motherboard should support the Advanced Clock Calibration feature, which currently only motherboards with AMD's SB750 southbridge chip support
* The Phenom II X3 processor should belong to the 0904 manufacturing batch, these should be some of the initial batches of the processor, and may still be found with retailers
