Build log: storage-oriented SR-2

[Sam_oslo]

I've been playing with SR-2 for a short time, and it is very sensitive to IOH-voltage. Too little of it messes up the PCIe dramatically and reduces the 3D-performance a lot, even tho it seams stable and can run Prime95. The QPI of 5520 chipset is designed to talk to tow CPUs, and using one CPU may have some kind of negative effect on PCIe too?.

Is it possible that PCIe-settings/performance has been affecting the performance here?
