Well, the process is pretty much the same, get yourself the Phenom II x2 555BE for around $99 (Rs 5000 on Indian shores) and a motherboard with either the SB710 or SB750 and you are good to go.


The process is same as before, just go into the BIOS and have a look at the ACC- advance clock calibration settings. Set the ACC to auto and EC firmware selection to hybrid and that’s it, you are good to go, save settings and reboot.



So what is new? It’s the same as the 550BE, but I feel that you have a better chance to get a Quad core from a 555BE than a 550BE. This is because, initially, when the Phenom II X4 was introduced, its yield were poor and so they had a chance to use those binned chips for the dual core version. Hence, only a few select batches of the 550BE could be made into a Quad core, but things have changed now. The yields of the quad are much better now. As AMD has already made a market for these products, they need to disable 2 cores of a quad and sell it cheaper than they like. So you could gamble on a 555BE and turn it into a quad and you have pretty good chances of doing so. But it could turn out that you get a Quad core processor, but it’s not 100% stable. You could face other minor issues such as the temperature diodes to malfunction. There is no guarantee but it’s worth a shot! You can get a 3.2GHz Quad core processor for $99 and the money you save (approx. $60) can be used for better graphics card or a better PSU.
