Hi hikerman, nice rig you've built.
Go to your motherboard support site and install all the drivers from there, the drivers on the CD are usually old versions.
G1.Sniper 3 Support - Drivers
With 32GB RAM you're going to have to make a few adjustments to get it stable.
Are the CPUZ tabs you posted taken from the system at idle or under a load?
I noticed something strange, your XMP setting on the CPUZ SPD tab (this is where the system gets the settings from) is 10-13-13-33 and the Memory tab (what you actually have) is 10-12-12-31. These should match the SPD tab information.
Go to your XMP profile setting in BIOS, picture #11 in your BIOS link, and select 'Profile 2'.
This should be the same as the CPUZ SPD tab XMP-2000, 1000MHz, 10-13-13-32.
Memory scaling for Ivy Bridge is very small at the top end, this means you won't notice the difference between 2400MHz and 2000MHz.
You should be running 1.50v RAM, it's the recommended RAM voltage. The 1.65v RAM with 32GB and the voltage adjustments will cause the CPU to run hotter.
Post the CPUZ Memory tab here after you make the change.
Weather in XMP Profile1 or Profile2 make the BIOS changes below.
Let's stay with the Profile2 settings for now.
The two voltages we need are on picture #7 in your BIOS link.
CPU VTT and IMC, these are the Integrated Memory Controller voltages.
Bump your CPU VTT to 1.2v and the IMC to 1.195v.
If this is stable we can back them down a little until they're unstable, then up a notch.
For a quick CPU/RAM stability test run CPU:OCCT
OCCT stability checking tool
Run the CPU:OCCT test for at least 30 minutes, be sure to monitor your CPU and GPU temps.
Set the time before you start.
When its done, pass or fail, it will make some graphs. Post these here as they are useful for analyses.
