Overclocking
The X3 8750 made it up to 2.8GHz (well, OK, 2.796GHz, if you want to be exact) on a 233MHz HT clock without much fuss, at stock voltage, but then it hit a wall. I tried raising the core voltage as high as 1.432V, but was unable to get it to boot Windows when clocked at 2.88GHz. Dropping down to 2.82GHz wasn't any help, either. So I settled on 2.8GHz.

Notice that the north bridge is overclocked to 2.1GHz in the screenshot above. Our MSI K9A2 Platinum motherboard apparently had no facility for adjusting the north bridge multiplier or for locking down the PCI Express clock. Either one of these things may have been holding back my overclocking efforts, but it's hard to say. That's a true disappointment, because the K9A2 Platinum is one of the better, more reasonably priced Socket AM2+ motherboards around. Asus' 790FX board is more tweakable, but costs more than any Phenom, which is a little upside down. If you want to overclock a Phenom, you're better off getting the Phenom X4 9850 Black Edition, which has an unlocked multiplier.
