very nice, that 32m is gettin low, just the memory holding you back. If you are testing just your memory, you should have your cpu on a low multiplier like 9. And have your memory divider at 200 (400) 1:1. So you know it's just the memory that could be unstable.
Try going with memtest86+ to test that memory, that's the quickest and best way to test stability quickly for memory....either way, you are running at my daily speed right now, i just run about 50mhz higher on the memory
