I have an ASUS A7V8X-X with an AMD XP 2500+. I have 512 Mb of DDR PC2700 and 512 Mb of DDR PC3200 RAM.
I have been experimenting with some filters in DVD Rebuilder. This process often takes a few hours hours to encode a DVD so in order to speed up the process I decided to check out the overclocking possibilities of this machine.
I can overclock in three different ways:
(1) increase the CPU multiplier -- For example changing the multiplier from 11.0 to 12.5 effectively increases the CPU speed from 1.8GHz to 2.0GHz. This does not change the FSB.
(2) increase the CPU external frequencies -- For example changing this from 166 to 182 increases CPU speed from 1.8GHz to 2.0GHz, changes the FSB to 182MHz and changes the memory frequency to 364MHz.
(3) increase both the CPU multiplier and the CPU external frequencies -- For example changing the CPU multiplier to 11.5 and the CPU external frequencies from 166 to 192 increases the CPU speed to 2.2GHz, the FSB to 192MHz, and the memory frequency to 384MHz
I ran tests using Sandra Lite 2007 benchmarks on these three examples and received the following scores:
(1) Multi-Media-39428 Memory-3899
(2) Multi-Media-37986 Memory-4219
(3) Multi-Media-42011 Memory-4471
Note that these tests I took out the PC 2700 because I overclocked beyond the capacity of this RAM. I can get 512Mb of PC 3200 pretty cheap ($26.00) if it turns out it would be worth it.
What is the best way to overclock this machine to improve the encoding times? The machine was stable when operated as shown in the three examples but I have not done a stress test in any of them. I did increase the core voltage at the higher overclocking frequencies and CPU temps hardly increased.
I realize the risk I'm taking but I'm willing to do it.
