You may be able to unlock the 4th core IF your board supports "core unlocking". Also, the CPU has to be able to be unlocked (some can, some can't). And even if you are able to unlock it, there's no guarantee the system will be stable. Some cores are disabled because they're defective, some are disabled simply to create the X3. In other words, it's a crap shoot.

Motherboard is an Asus M2N68. The updated bios lets me overclock but I don't see a setting to try unlocking the 4th core.

Boards that are based on AMD chipsets & support ACC (Advanced Clock Calibration) can unlock the cores. Nvidia based boards need to support NCC (Nvidia Core Calibration). Check your motherboard manual or the ASUS website.

Just from looking around it doesn't look like that board supports ACC.

or just go buy a Athlon II X4 630 for about the same price you would buy a new motherboard.

i dont think the MB you have will unlock it to a X4, but if you go with the ASUS M4A88T-M LE, it will unlock it in unleash mode. but some 450 cpu's are unstable with all 4 cores. the first one i had was stable for about 4hrs, and then it burned up the 2nd and 4th core (leaving it unusable). the 2nd one i bought is not stable in unleash mode (all 4 cores), but it is stable at 10% OC DDR3 RAM and 12% OC CPU.

AMD's desktop processor line up comprises of three product names - Sempron, Athlon II, and Phenom II. These CPU's are derived from two sets of basic designs. Both families have that is The two designs used in Athlon II products are the quad core Propus and the dual core Regor. By disabling a core on these parts, AMD creates the triple core Athlon II X3 Rana and the single core Sempron Sargas product lines.

IT is not a crap shoot, they are four core processors from the factory.

That means unlocking those models are stable.

yes they are four cores from the factory but didnt u read the first response plus this is all computer logic. why would a company disable a core on a cpu while if they enable it they know they will get more buys than a triple core or dual core? they disable it bcz it was a bad core and for the market and business for competetion with other cpu makers like intel. some AMD processors can be enabled some cant. u speak of the Athlon Rana how can u be sure the fourth core can be enabled?did u try it b4?
think abt this a 9800gt has 112cores nvidia laser cuts extra cores on all cards now if they did not a 9800gt could be a 9800gtx with 128 cores its all computing and business.
