Windows 10: Tested all ram sticks and all slots but when I install all ram my pc crashes

I've been getting DPC_WATCHDOG_VIOLATION BSOD for a while now almost as soon as it starts. I've tested my gpu in another box and had it running stably. I replaced the PSU in the new machine with one I know works. I finally turned to thinking it's a RAM issue. I tested every stick of RAM I have one by one in slot 1 and things were stable when starting and using the PC, I then tested the stick I tested most thoroughly in each DIMM slot one by one. Finally, I tried putting all RAM back because I thought maybe I seated them improperly by mistake. That was finally what caused the crashing to come b

Looking for free app to test RAM sticks and slots

I am having issues resulting in the BSOD and after doing a number of things, I have come to the conclusion that my problem is either a RAM stick and/or a memory socket. Without going into EVERYTHING that I have already done and what else it might be, what I am doing here is simply asking for a free app to test RAM sticks and slots. I am hoping to identify specific sticks and/or slots. I am running a current version of Windows 11 Pro on a gamer computer (ASUS MB and G.SKILL RAM). The Windows Memory Diagnostics promises to tell me what it found after rebooting, but, it never does. Thanks.

 

pc crashing with two ram sticks .

I have just tested my pc with individual ram sticks and it is crashing only with one particular ram stick, ill rma that and see if the issue still occurs,

Thank you for the help.

 

 RAM TEST

I've had a few more BSODs, however when I went to create the usual dm log, I noticed it say there were no minidumps. My computer did recently update to Fall Creators, and I don't have the 'Disable automatic deletion of memory dumps when disk space is low' ticked, but the drive isn't even half full.

Anyways, I'm going to try some more troubleshooting steps and wanted to run them by the thread before actually doing them:
- Re-seat graphics card and memory. Already done today, will be doing a test (aka, normal nightly gaming) to see if it crashes.
- Move a crash-prone game to third hard drive and unplug current
- Swap out my 1080 for my old 750TI I still have lying around
- Buy a single 16GB DDR4 RAM stick and use that in a different slot. Unfortunately my cooler covers one of the memory slots, so I can have a max of 3 sticks. If nothing else, I'm upgrading to 32GB of RAM =P Probably last test b/c it involves spending money
- Reinstall Windows

Anyone have a suggested order I should attempt these in? I'm thinking next step is probably either install on third drive and unplug second, or swap graphics cards
