Memtest shows slightly different memory access values between the two different steppings: Stepping 10 is slightly slower accessing RAM and a bit faster accessing L2 cache.
Maybe the memory timing has something to do with the nvidia driver. Has anyone else here the opportunity to test different chips? I will write to NVIDIA tomorrow to tell them about this. Maybe others can do too.
Where can I find out the stepping of my cpu?
I took a photo before installing it.
