I have an ASRock X79-Extreme9 motherboard and i7-3930K CPU.
I've tried both a F3-12800CL9Q2-32GBZL (8x4GB) and F3-12800CL10Q-32GBZL (4x8GB) kits and I cannot get all memory to work.
With all DIMMs from either kit my machine will not POST. I've tried the standard BIOS and also the latest and neither works.
With the 8x4 kit, I can get 6 DIMMs working for 24 GB. I think 7 DIMMs do actually work and there is just one that doesn't reliably POST. (i.e. it has a couple of times but will not reboot).
With the 4x8 kit, I can only get 2 DIMMs working. If I swap these for the other two I get either a failure to POST or intermittent reboots on the way to the OS starting.
Have I just been really unlucky and got 2 kits that don't work or is there something else I'm missing?
