Memory BIOS settings?

I'll try to help.
First, shut down and unplug your pc; then remove and reinsert all the RAM sticks. Make sure they are installed properly and that they go all the way down into the slots and lock.
Re-boot and press 'delete' during boot screen to get into the UEFI.
If you haven't already selected the "Advanced" UEFI, find that and select it; you might have to reboot, I don't recall.
Once the UEFI opens in advanced mode ooohhhh hell. I'll be right back. I have to reboot and find the right tabs etc.
Back
UPDATE 1925hrs. PST. Back again.
I really shouldn't be on here after a days worth of work. Forgot the simplest thing. Before you read further, simply go into the UEFI, click on the last tab at the top "Exit", and then click on "Load defauts and exit" or something like that. That will set the BIOS to the default settings and the computer should boot. EVERYthing after this will help you set up your RAM to factory specs.
O.k., on the opening advanced screen click on "AI Tweeker". Your current memory frequency should be shown in yellow at the top, and also in the rt. hand box across from "Memory Frequency". You didn't tell us the speed of your RAM (1333, 1600, 1866 ??), but make sure that the freq. shown agrees with the manufacture's specifications; if it is higher, click on that box and select the correct speed. You can do that if it is lower also (On first boot my 1600 showed up as 1333 which is the boards default setting), but RAM should run at slower speeds just fine.
Do not worry about timing at this point, we are trying to get the PC up and running; you can deal with timings etc. later. Voltages too.
Next: Set your "Ai Overclock Tuner' to 'Auto'
Scroll down to "DRAM Timing Control" and DRAM Driving Control and make sure those are on Auto.
Next step; At top of UEFI click 'Advanced'. Click on the second item down, "North Bridge Config."
Set the first item, IOMMU, at "disabled"
Click on 'Memory Configuration'
There are six items; top-to-bottom make them, Auto, Auto, Disabled, Disabled, Enabled, Disabled.
Back out of there, and click on the top tab "Boot". Disable full Screen logo
Finally click Exit and select save and exit;
HOPEfully the computer will boot.
