Can't figure out this BSOD, keeps happening

First thing to do when changing the RAM settings is to run memtest86+, run 7 full tests (test #1 through #7), best to run overnight as it will take a while.
If you get any errors you can stop the test.
Let us know the results.
What is the QPI/Vtt voltage set at?
If it is still at 'Qpi/vtt 1.175' bump it to 1.220v.
The 'Command Rate' is on page 45 & 46 of your motherboard manual.

Seems to only happen when I have all 6 sticks in for the full 24 gigs. For the moment I have removed three of them.

Welcome back.
That is due to the voltage settings, the more RAM cards, more memory chips, they will need more voltage to run.
The fact that is runs stable with 3x4GB RAM cards confirms it's a voltage and settings issue.
If you run 3x2GB RAM and the Qpi/vtt (integrated memory controller) voltage is 1.10v, which is the default setting they are for 4-6 GB, then you change that to 6x4GB, all the RAM cards are going to get less than 1.10v.
They won't like that, and will let you know.
Go back a few posts for how to find it and change the 'Command Rate' to 2T.
Did you bump the QPI/Vtt voltage from 1.175, 1.220v?
If you want to try and get the RAM stable at 1600Mhz you're going to have to bump the DRAM voltage and the QPI/Vtt voltage.
Bump the DRAM voltage to 1.70v and the QPI/Vtt voltage to 1.220v, check with all six RAM cards if it boots up, then run memtest86+ for a full 7 passes.
Best to run overnight, if you get any errors you can stop the test.

I was running 1.65v. That's what is printed on the RAM. I don't think I bumped this up. I can't remember at the moment.Welcome back.

I did these two things.Go back a few posts for how to find it and change the 'Command Rate' to 2T.

I'll try setting the DRAM voltage a bit higher and check back in with the results. Thanks for the help.If you want to try and get the RAM stable at 1600Mhz you're going to have to bump the DRAM voltage and the QPI/Vtt voltage.

Went ahead and bumped up DRAM Voltage to 1.70. I don't see that change reflected in CPUz, though.

If your looking at the CPUZ SPD tab it won't show there, the SPD Tab voltage is the manufacturer tested voltage and is a recommended setting, and since they don't test every board these need adjusting sometimes.
You have to look in your BIOS for the RAM voltages, the only real time voltage displayed in CPUZ is the CPU voltage.
Did you run memtest86+ with all 6 RAM cards installed?

Not yet but I may not have to. Yesterday afternoon my computer randomly restarted. No error message, no crash, no blue screen. If I remember to run it tonight, I will. Brain is cluttered with flight school.

Did you have 3 RAM cards installed or all 6?
What PSU do you have?
Brand and wattage rating.
Make sure your minidump setting are correct, as in post #2.
A random restart is caused by a BSoD or a component fault, the PSU is the first thing to check.Then, follow the directions here to set your system for Minidumps (much smaller than the MEMORY.DMP file): Set MiniDump
