About four years ago now the company I work for were investing in some new servers for a project that we were working on and what turned up were quad LGA1366 socket Xeons with support for up to 192Gb of memory.In most cases two sockets were populated with Intel Xeon X5670 CPUs, hex core devices with 12Mb of cache memory. I looked around and noticed that HP were doing a very similar board with two sockets and, crucially, it was packaged up into what looked like a normal PC tower case.It swallows the Z800 motherboard as if it were designed for it. I mentioned before that the motherboard mounting holes do not match up with the corresponding holes in the case’s motherboard tray.I had to drill and tap new holes for enough screws to hold the board safely with its heavy load of up to two CPUs with large heatsink/fans attached. Before starting I fitted a small random PCI card into the motherboard and used it to work out exactly where the board needed to be so that the cards lined up with their fixing holes on the side of the case.The worst issues seem to be with dual-CPU configurations.Later on this article I’ll go through my own setup and experiences.
It shows the pinout of the power cable, taken as you hold the cable and look at the connector. Each of the pins in the connector is physically keyed with either a square or a slightly rounded socket and there are only 18 pins.We need to start with a case for this thing and like I said, even the largest ‘normal’ tower case will be too small. There aren’t many of these and the one I chose was the Nanoxia Deep Silence 6.I got it from Quiet PC in the UK and managed to grab a B-grade bargain at £139, that’s a £50 reduction on the full price and I couldn’t tell what made it B-grade because it looks perfect to me. I can confirm what the online reviews say when they describe this case as being massive. I expect that if it were hollowed out then I could fit my current Fractal Design tower case inside it.It’s very highly thought of and should be more than enough for this system.I mentioned before that some of the board power connectors are non-standard, in fact only the 8-pin EPS connector has a standard pinout and fitting.
