Finally got a motherboard that sees all the memory and all the SATA ports. The server is operational though I still have to do some configuring and stress testing to determine how fast the CPU will operate stable and within thermal limits. But it is basically operational at this point. I hope to place it back into service this coming Thursday.
I was asked by Mark Richards to take some photos of the build so I’ve taken some at very stages of cabling.
This was the initial install of the motherboard, before I had the CPU cooler in place or the video card and none of the wiring is connected yet.
This is the backside. You can see that the wiring is a completely disorganized mess. This is mainly the result of six previous motherboard replacements, many having the connectors located at different locations and I did not want to tie everything down until I knew it was working.
At this point, I’ve started to organize the wiring a bit. You can see I’ve got the power cables all wire tied together so they’re not spread out all over the place. Still not routed nice but at least neat bundles now.
The front side with CPU cooler and video card in place. I wanted to add an additional network card but turned out the intel card I bought off of amazon was defective and the dealer had a super short return interval which I felt was kind of slimy but oh well it only cost me $15 so not the end of the world..
Getting neater. The orientation is a bit weird in this photo as the computer is on it’s side at the moment as this was just the easiest way to work on it doing what I was doing at the moment.
This is the final backside wiring before I connected the drives. The backside cut-through holes were so stuffed, I had to place some of the disk cables through the space between the disk carrier and the case because there just wasn’t room for any more wiring in the pass through. The main thing that caused that was the excessively huge power supply cables. Unfortunately, when you have a CPU that draws 540 watts, that’s 108 ampers at 5v, and 16 or 18 gauge just does not cut it at those current levels.
This is the final backside wiring.
This is the final topside with CPU cooler and video card in place. Note that this is a Noctua 15D cooler, the stock 1500 RPM fans have been replaced with 3000 RPM fans and the thermal paste used is Kryonaut Extreme. The combination allows me to get away with 540 watts of dissipation while keeping the CPU temperature below 86C. Most water coolers won’t do as well. This is noisy as all hell but given the co-lo facility sounds like a 747 taking off and the fans only spin up to full noisy speed when the CPU is fully occupied which really only happens using a small FFT stress test program. Even compiling only results in about half the heat with all threads occupied.
So now to do some testing to find out how fast I can run the CPU while keeping it stable and under 86C (this CPU won’t be destroyed by going over that, Intel engineers tell me even 107C won’t destroy it but that it tends to become unstable and make errors above 86C so I set 86C as the throttle temperature on the motherboard to prevent that from happening. Under real world loads though this is not a real issue.
