yes. go to your computer shop and ask them for 2-3 choices of amd 720be processors. Then when you get them in hand, you can see the processor inside via transparent side. Read the batch no. and thats it!!!
BTW now a days new 0907 stock is coming and not the old 0904 so the nes stock doesn’t unlocks the 4th core no matter which board u get.
I 'm too got 0907cpmw batch which has no 4th core,
but who cares, 3 cores are still way better coz even 4th core is not guaranteed stable even at stock IMO.
