Well finally had enough parts to get my new beast going the other day. Everything except the GTX790 but I had an old 480 not doing anything so will use that till the budget allows.
Put the 32GB of memory in and the 2x3TB hard drives, plugged the power cable in and pushed the button.
Wow what a letdown
The cooling fans gave a kick, the corsair water pump ring light came on for an instant and the memory lights came on and stayed on. Could not get it past that point. No POST, nothing.
So stripped out the video card, memory, and unplugged the drives. If it was any of these it should at least start the fans and POST. Still no go. That left CPU, power supply or MB.
Took out the power supply and put in in my currently working PC and it fired up no problem so not power supply. CPU or MB. Emailed the place I got it from and they RMA'ed the MB back and said they had been having a few issues lately with Gigabyte MB's. Were going to test it themselves and send me a replacement but I decided to spend some extra and get a Asus P9X79 Deluxe instead.
I bought a Gigabyte board years ago and it was a dud right out of the box. I haven't touched another one since. I also replaced it with an ASUS board. My two desktops and my laptop are ASUS.
Well the new Asus board turned up and once I had everything in it booted fine so definitely the motherboard. This is the second dud I have had. The first was one with the cpu socket pins with a finger depression in it. Was a while ago now.
The new system is lovely. As a start point I cranked it up to 4.3Ghz and run Prime95 for about 30 minutes. Stable as and cpu temp topped out at 43 degrees. My other PC tops out at 4.1Ghz and would be running at about 87 degrees and would be unstable.
WEI says 8.1 which is the drive as the lowest score. CPU/Mem was 8.7
Simply loving it.
I gave it the extreme test with the Asus software and it took it out to 5.0Ghz before it crashed at 100% load all 6 cores. Said it was stable at 4.9 but it did not reboot properly so took it back to 4.8.
