To identify the CPU you need the code printed on it.
Both CPU versions of 965 are Black Edition they are both unlocked.
You can easily overclock them by rising the multiplier one notch.The problem with the 140W TDP one is that it s already at it s peak and so might be the motherboard.
If you are reaching 50-55 Celsius now ,stock , when in load , then yes you may be able to overclock ,but keep in mind :
-the CPU temperature must be below 65 Celsius at all times
-the motherboard CPU VRM may reach it s limit quite quickly (it s budged board) , this meaning either that it will not provide enough overclocking headroom either you will see sparks from it
-rising the clock will bring more noise from the stock cooler ,so you may hear some airplane engine sounds coming from the PC
So if the temperature is already at over 60 Celsius in load you should forget about overclocking just to be on the safe side.
