Glad to see it's hashing. Now that it's doing that but only with three blades, I've only seen this under a few circumstances:
1) Powersupply is too weak, regardless of what the numbers say (some are sensitive to initial draw, etc)
2) Some blades aren't seated properly and/or are running too hot - if you haven't already, open it up, tighten the heatsink screws and reseat the blades solidly.
3) (rarely) Cube is simply "confused" and clicking on the Update button on bottom right can restart it
thanks.
Heatsinks are screwed tight, None of my blades were in the grooves of the case, two weren't seated properly. I think it might be the PSU - it's a 550w corsair, i just pulled one of the pci-e plugs that has a removable extra two prongs and used a p6(?) > pci-e adapter. Now have five out of six blades working, none of them running all chips or at full speed. Still only running 5ghs. I'm going to try with two psu's - unless of course someone tells me that is a bad idea...
