Phenom II X2 555

[Betamax-]

Hi,

Its always good to get more for your money and ive heard that the above processor can sometimes allow you to unlock an extra 2 cores making it an x4 equivalent if you have the right chipset on your mobo...

Ive seen the proc going for around £60 these days so seems like a good cheapo way of upgrading..

Has anyone tried this on a crosshair 3 mobo? Ive googled this and seems that it may only work with 790GX chipset but the crosshair is 790FX..

Any ideas???

In general, make sure the motherboard has a SB710 or SB750 southbridge and ACC is supported before purchasing. However, there are exceptions, as some motherboard manufacturers have disabled ACC core unlocking features. Rumors were floating around that AMD discouraged theO unlocking of cores. Hopefully the following list will clarify which motherboards work and which ones don't. Keep in mind that the BIOS revision plays an important role in unlocking. For example, with the Biostar TA790GX 128M motherboard, only 78DEA113 bios unlocks cores. The 78DEA525 bios DOES NOT UNLOCK ANYTHING.

Yes you can unlock the extra cores with the crosshair iii.

Be careful with updating to the latest BIOS though, I heard some companies are removing the ACC function that unlocks the CPUs with some of the newer BIOS. I guess AMD doesn't want people to buy cheap unlocked quads for half the price of the real thing.
