Here are my specs
i7 9700k at 4.97Ghz
Gtx 1660ti SC ULTRA
16 GB DDR4 supposed to run 3200mhz but computer wants to run it at 2770
Z390-p
500w EVGA power suppply.


You can skip this background information if you already know the answer to the question I ask in the second paragraph, this is all just background information to help with diagnostics.

Everyone told me on here overclocking ram is a fools game, but im foolish enough to do it. It makes such a difference you would not believe it. So to start off with, yes the CPU runs stable at the insane overclock. Its a noticeable improvement, but in some locations in the specific game I am sacrificing my systems longevity for, its not enough to keep me over 50 FPS. I know that sounds high already but i need that solid 60 because dropping from 75 to 48 is extremely noticeable. Believe it or not, for whatever reason, when I moved my RAM up to 3200 mhz (which is what it is advertised at), it cured the disease that is FPS lag in that game. In locations I previously capped at 75 I was capping at 105. No idea why. Anyways, it eventually crashed. Upon reopening the game, it crashed again. So did my computer this time it gave me that blue screen that says were collecting data. I moved the overclock on the RAM down to 3051 and it was a noticeable decrease of about 5 FPS but made the game run well. Unfortunately, given enough time it wound up being the same story. I currently have the RAM at 2987 and just a random game I knew I could run crashed at some point over night (I left it running because it takes so long for RAM to crash). The computer did not crash.

That all being said, is it possible that because I have the cpu be overclocked so much, it is pulling too much voltage for my RAM to pull voltage for its overclock? I know I sound like a dummy but I dont know a way to monitor my voltage. Something interesting I did notice while looking through my BIOS just now is that, because I let my computer determine what my best stable OC for my CPU was, it set the voltage and all that for me. With my RAM I am enabling XMP I and just setting it manually. The voltage does not go up when I increase the clock. It sits at 1.2000 regardless. How do I know what I can safely increase this to? Everyone online just says put that at 3.5 but thats an insane jump and I figure I had better ask first. What other reasons do you guys know that would cause the crashing?

In my Bios, XMP is enabled, and under my AI tweaker I have it set to XMP I. Under my DRAM memory I am given the option of "auto" or I can manually set it to any frequency. I changed that frequency, but have not changed any voltage rates associated. With everything set to auto, the voltage is at 1.2000. It does not change if I manually change the clock rate. Do you think I can safely increase the voltage to 1.35v?

I notice in that specifically the RAM is running waaaaaay below where it should. It suggests turning on xmp but I already do have it on. This is likely because of the low voltage/using it at the clock rate my computer wants to instead of what it should be at. I want to...
How old is that 500w EVGA power supply?

Specs?

Past history of heavy use for gaming?
The PSU may not be able to keep up with the power demands/peaks of the host system.

The PSU is almost 10 years old. I have used this computer for gaming since the day I made it, but I have the mobo I had before did not support overclocking so Ive not been overclocked for very long, RAM just now being overclocked. Im not sure how to give you more specs on the PSU so I am just going to send you a picture of the info on it.

SO are you using XMP or manually setting the memory?

It should be 1.35 volts.

Run this and post a link to the results.
 
Very likely that a new PSU is needed.

A couple of suggestions:

1) Power down, unplug, open the case.

Clean out dust and debris. (Noticed what appears to be quite a bit of dust, fibers, hairs, etc. in the picture.)

Ensure that all connectors, cards, RAM, and jumpers are fully and firmly in place.

However, that is just an interim suggestion that might help keep the PSU going a bit longer.

2) PSU - Read the following link from this Forum:

https://www.tomshardware.com/reviews/best-psus,4229.html

Two objectives:

1) Use the calculators to properly size a PSU for your system.

2) Start considering what PSU (make, model) to purchase depending on price and availability in your area.

This is likely because of the low voltage/using it at the clock rate my computer wants to instead of what it should be at. I want to change the voltage to your reccomendation but I will wait until I hear back from you if you think that is the solution.

By that memory part number it's rated for 2666 not 3200.

Is your memory in the correct slots as per the motherboard manual?
Set it to 3200 then raise the volts to 1.35
