Corsair H100i V2 240mm Liquid CPU cooler
Corsair RM850X 850W 80 Gold Plus
Zotac 1080 Amp Extreme

so have had 16 gigs of tridentz ram for a while now no problems, figured i would get 16 more because why not. so first i couldn't get it to boot with all 4 sticks in, i updated bios to latest version then i could get a first boot at 3200 with all 4 sticks off a complete cold boot. if i try to reboot from software or power button when it restarts my cpu cooler, vid card and most components only parshaly power up, no vid output at all so i did some tweaking i can get the system to run fine at 3000 on the ram. what can i do to get it running at the proper speed?

An answer you do not want to hear:

Sell your ram and buy a single 32gb kit.

Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this.
This is more difficult when 4 sticks are involved.
That is why ram vendors will NOT support ram that is not bought in one kit.

One thing you can try is to go into the bios and set the ram parameters yourself, do not use XMP.
Increase the ram voltage a notch; this may fix your problem.

Test with memtest86+.
You should be able to do a couple of full passes with NO errors.
