Jupiter:
You mentioned the "W83667HG sensor module". What is that for? What exactly did you do to set it up?
I was able to get the coretemp module to display temperatures with lm-sensors after I saw your mention that it works. It does indeed display (slightly different) temperatures for 8 virtual cores...weird, but the temperatures seem about right. I'm getting 29-32C now under low load. Earlier, I ran 8 processes that maxed out the virtual cores and did a lot of memory access and the temperatures rose to 63-66C.
I'm running a Gigabyte GA-EX58-UD5 motherboard (F4K BIOS), Core i7 965 at 3.2GHz with Noctua NH-U12P cooler, and 6x2GB G.Skill 1600 8-8-8-21 memory.
Memory latency is important to a lot of the work I do, so I was curious to measure it. It doesn't look like any of the Phoronix benchmarks deal with memory latency. Anyway, I used lmbench:
lat_mem_rd -t 32 256
"stride=256

It looks like L1 is about 1ns, L2 is 3-7ns (not sure why it rises before 256K), L3 is about 14ns, and RAM is 61ns.
The only issue I've had is that I cannot get the first LAN port to work with Ubuntu 8.10. I was originally using the r8169 module, but Realtek's website (and some posts on the web) indicate that r8168 is the correct driver. So I compiled and install r8168, and I still cannot access the first LAN port. The second LAN port works fine. I'm not sure if this is a BIOS issue or a linux driver issue.
