[SOLVED] Question about RAM

So I've had 32GB of g.skill trident z rgb 3000mhz ram in my computer since I built it about 2 years ago (bought at 2 separate times). I've also had issues with trying to run DOCP on it and having my windows crash on me at random times but it runs completely fine with it disabled. I just took it as maybe I have a bad module and I'm just too lazy to test it since it doesn't crash with DOCP turned off. However I was playing around in CPU-Z and realized that I have two different P/N... Two modules are P/N F4-3000C15-8GTZR (slot 1-2) and the other two are P/N P/N: F4-3000C16-8GTZR (slot 3-4). Would this be the cause of my crashes I wonder when I enable DOCP? And would it benefit to move the my ram around so each different P/N would be in slots 1-3 and 2-4?
 
Solution
Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
The internal workings are designed for the capacity of the kit.
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.

Run memtest86.
It boots from a usb stick and does not use windows.
You can download the free edition here:

If you can run a full pass with NO errors, your ram should be ok.

I am not familiar with DOCP, but I understand it to be like XMP which is a set of settings to run at 3000 speed.
If you are running at 3000 speed, no need to do anything else...

speeds faster than 2400 @1.2v or so are achieved by overclocking the ram.
XMP has those settings, and I imagine that so does DOCP.

It may be that your ram mismatch is causing your issues.
One thing I can suggest is to make the ram settings yourself. In particular, a bit higher ram voltage can iron out some incompatible issues.
