I have a Gigabyte GA-K8NS mobo. In the BIOS the CPU frequency is set at 200 and the multiplier at auto. This runs between 5 and 10, so 1000mhz to 2000mh. The cpu is a AMD64 3000+. Should I leave the multiplier at auto or set to 10 to get the maximum all the time?
I assume the system automatically ups the multiplier as more stress is placed on the cpu. The cpu temp runs at 27-35c. I have been thinking of overclocking too, by upping the cpu frequency to 210.
I think you'll find that the AMD 64 cpu's have a feature called "cool and quiet" which does the same trick as a laptop......it throttles back the cpu when demand is low to keep noise and power conssumption low.
If you are wanting to overclock the system you will need to disable this feature in the BIOS......ie you will need to set a manual multiplier rather than use Auto.
If you like I have an excellent write up on AMD overclocking posted by a member on the Custom Pc forums which I can send to you by the yellow envelope.
