Keep getting BSoD while gaming (Bad_Pool_Caller)

I recently built a new computer and after setting everything up, I overclocked my CPU, GPU, and set my RAM to 3200mHz (via XMP). I was getting repeated BSoD and after much frustration, I got rid of both OCs, yet was STILL getting the issue. I then reinstalled windows completely, and after an hour of gaming, got it yet again.

I was thinking the OC was the issue but now I feel like it has to be hardware, no? Also, I kept the RAM at 3200 via XMP, that shouldn't be a problem since that is what I bought, right? Do I have to return my GPU, RAM, CPU (got them all very recently)? Idk who is the culprit! :(

Specs:
MOBO: ASUS ROG Strix Z370-E Gaming
CPU: i7-8700k
RAM: CORSAIR Vengeance RGB Pro 32GB DDR4 3200 (PC4 25600)
GPU: MSI GeForce RTX 2080 GAMING X TRIO
PSU: RM1000x
SSD: Samsung 970 EVO 500GB - NVMe PCIe M.2 2280 SSD

After a system crash or bsod it will usually reset your OC's (not you CPU though). juicing your gpu with loads of power can often cause a crash. Right now the RTX 2080 is in a bad spot. If you want stability don't over clock it. Its already a beast. Just run your rtx at base settings. i'm sure CS GO will look great.

Nvidia had apparently released a 'bad batch' of rtx cards.

Best luck,
Harry

Yeah, unfortunately I've gotten rid of the OC on the card and I still got the BSoD. The error in my OP is with no CPU or GPU OC, just RAM set to 3200. Based on everything in my post, do you think I have a bad card? Is there a way to test it? It has previously passed a couple hour RealBench stress test

Edit: Also, I bought both my RAM and GPU from Newegg and it's within the return window. Is there any possibility at all that it could be my RAM or only GPU? Because I could return both

You can run a ram check to test your ram. I think you just need to stay ontop of driver updates for the rtx or return it. I think there was also a bug that would give you a blackscreen if you weren't using a display port for the rtx. I stopped reading about it because they stopped making them.

[strike]Hmm, I looked into returning my GPU and it is only eligible for replacement (newegg)...so I guess I have to try another of the same card and hope for the best? [/strike]Actually I was able to get a refund! What would be the best card to get instead? I've heard 1080Ti's are the way to go?

I'm thinking about returning my RAM (4x8GB 3200) just for good measure and getting 4x8GB 3000 C15 instead. Thoughts?

1080 TI's are monster gpu's. You can't go wrong with that choice. If you want to rtm you RAM go ahead, but I doubt it's the RAM.
It's like Dr.House says: "It's never lupus" I believe "It's never the RAM"

Haha alright sounds good :p I'm gonna replace the GPU and report back! Really appreciate the help :)
 
you could also provide the memory.dmp file and the minidump file and I can check for common problems.
ie put the files on a cloud server, share the files for public access and post a link.

(this assumes you have not all ready shipped your hardware back)
