Poking around the internet tonight, I happened to find a program called CrystalCPUID, which can change multiplier settings and voltages on the fly. I have a K8N Neo S754 motherboard and a newcastle 3000+ (CG stepping). Since the bios of the motherboard does not allow for 0.5x multiplier adjustments, only integer adjustments, I was shocked that the 0.5x multipliers actually worked!!! I have been running tests for a while using SANDRA, CPUID, and 3DMark to confirm that the 0.5x multipliers work. Below is some data:
Sandra
CPU Arithmetic Int/FPU - FPU/SSE2
5x200 - 4430/1579/2058
5.5x200 - 4732/1737/2265
6x200 - 5213/1895/2471
3DMark 2001 Car Chase Low/High
8.5x200 - 187.5/66.7
9x200 - 193.9/69.9
9.5x200 - 196.9/74.1
10x200 - 199.3/79.4
This program is great since it allows for much better tweaking. No more being confined to integer multipliers! Combine it with the nvidia system utility to control HTT speed and you have most of the overclocking options you'd need (aside from HTT and memory voltage tweaks). Post your results here if this helps you get a few more MHz out of your overclocks.
