Ram stability problem after gpu upgrade

I recently upgraded my 2080 ti XC for a 3080 ti FTW3 ultra and did some benchmark to see if everything was running smoothly. I started having some crashes in games like rdr2 and cyberpunk and got worried my gpu was faulty but then while doing some more benchmarking, I realized something was wrong with my cpu score in time spy extreme. Looking at past result with the same cpu I saw that the score was way lower than it use to so first thing that got to mind was the memory speed got reset somehow ( I have a old threadriper 1950x ). Turns out I was right so I went in the bios and turned XMP back up and test the games again, still crashing. and when I rebooted my pc it would turn on and off itself 3 times before working sometimes and resetting my ram to normal. I originally had 4 sticks of 8gb tridentZ 3200mhz installed in the computer, but upgraded by adding two sticks of the same ram but 16gb each ( same frequency and timing and brand/model ) because I needed more when working in substance painter. I removed both 16gb rams sticks to see if it would make any difference and turns out the xmp profile is stable again now and the games don't crash anymore... Can the card pull to much from the board and make it unstable now with all 64gb of ram in? Is there a way I could make it more stable without having to remove the two 16gb stick or reducing the frequency? I know first gen ryzen isn't the most stable with ram, I want to upgrade but I'm waiting for zen 4 and ddr5.

 

here's what's inside:

Motherboard: GIGABYTE X399 AORUS Gaming 7

RAM: 64GB DDR4 G.SKILL TridentZ RGB 3200MHz (4x8gb + 2x16gb)

GPU: EVGA RTX 3080 Ti FTW3 ULTRA 12GB

Storage: WD BLACK NVMe m.2 SSD 1TB | Seagate Hybrid Drive 2TB | Seagate 4TB 7200 RPM

PSU: EVGA SuperNOVA P2 80+ PLATINUM 1000W

It's not the card, RTX 3080 Ti, pulling more power from the board.

It's is because adding more memory sticks puts more stress on the CPU's Integrated Memory Controller (IMC).

 

Kind of like...instead of looking at 4 kids at the same time, you are now looking after 6 kids.

You need to slow things down (i.e. lower frequency), otherwise you'll run into mistakes.

 

If you look at overclocking highscores, most run a 2-stick configuration, over 4-sticks or more.

Fewer sticks, less stress / load on the IMC, and higher XMP / DRAM overclock frequency.

It's not advised to mix memory kits like this because it can cause issues. You'll probably have to adjust timings manually.
