I didn't find alot of stuff on your bios in the a7 manual, basically use the auto-overclock feature and set the recovery panel to "automatically restore default settings" or previously working speed if that is an option. I did see their warning about going over 110% but what I don't see is where you can control your HTT separately from the memory/databus/expansionbus/ frequency's or if you can lock your agp/pci/memory saparate from the cpu ht/htt. If you could decrease your memory to 166/333ddr, then set your htt up much higher, so you acheive a higher CPU internal fsb, once you find your stable internal fsb lower it so that the cpu speed is approximately 30% lower than your max stable overclock then start increasing your memory fsb, this should have a side result in higher cpu speed but you need to test and retest your memory fsb on the way up to 400ddr You should get close to your first highest acheivable cpu htt/mult but because this is increasing both the processing power and the total memory bandwidth you will have higher performance over-all than just setting the htt.
