Yesterday we had a first test with Classified E760 and our Xeon W3540 together with ln2. We could reach this:

Unfortunately efficiency isn't really good. But we have to deal with a horrible coldboot-bug at -27 degrees. Once the system is up and running we can reset and reboot normally. But once we change uclk, memory-timings and/or qpi-settings, the system shuts down completely and we only can boot again when the temperature is at -27 or less.

So we just set "safe" uclk and memory-timings and started to look for max frequency of our xeon. It passed cpu-test at 5,460 mhz but at full run it only reached frame 39 of cpu-test #2. So maybe with finetuning we can pass the whole benchmark at this frequency.
