Three out of the PC's in my house use AMD Processors. About 18 months ago I upgraded my sons system for his 2008 XMas gift. He got a Asus P5Q mobo with a E7300 CPU and 2 x 2GB of Corsair 6400 DDR2 memory.
Now that his PC is getting a bit older we'd like to O/C it a bit. Unfortunately, the settings are so very different then the AMD mobo's I am used to. I managed to drop his multiplier to 9x and then set his memory to a higher value (854 (427x2)). That increased his memory speed, but the total clock speed was slightly slower due to the 9x multiplier. When I reset the multiplier to 10x unfortunately, the motherboard decided to change the FSB : Memory divider to keep the CPU at the same 2.66Ghz speed (same as 10x400 with a 3:2 divider).
I still have the manual, but figured that I would ask here for some real world settings rather then figure it out from the owners manual myself.
Perhaps I should mention that I disabled both settings that throttled down the multiplier in BIOS already. For some reason, while he was gaming he'd get horrible sporadic drops in frame rate. Disabling the Speed Step settings seems to have fixed that problem (but I don't know if it is an indication of a failing Mobo).
Last but not least, he has a stock cooler and a case with very good ventilation. We don't expect miracles, but a modest bump in core speed might help us use this combo until we move him up to a quad (or hex) core in a year or three. Of course the other alternative would be to buy a Core2Quad CPU, but I'd rather not spend the money for one at the moment.
