Vcore is correct in cpuz and that is the first one I have tried, looking forward to testing the remaining ones I will take the other five cold as well, just waiting for more juice to get here on Tuesday. I only have 20L or less so I think I am going to give the X5260 a spin for hwbot prime as well, should be interesting as there is not much data on these Xeon's.
I saw you got a 9600 PI kit, they're very nice and they should be good for 650 MHz CL5.
You could try the outer memory slots too, the inner ones might not be the best for achieving high memory clocks.

Did you try higher Vcore? 1.632V seems so low for Core 2, but the low power bin might not like higher Vcore. I'm curious what's the case here!
Can you run some other benchmarks ( like SPi etc ) on the two Xeons when you got some time?
