Question BSODs after upgrading to 16 GB

[smmm]

Hello,

I recently upgraded my Dell XPS 8700 from 8 GB of RAM to 16 GB, and I have been experiencing frequent BSODs.

Here is the multiple things it has said the errors were:

Unexpected kernel mode trap

KMode exception not handled

Driver power state failiure

System_service_exception - What failed: win32full.sys

Driver irql not less or equal - What failed: nvlddmkm.sys

Those last ones are a bit more detailed because I took pictures of them. I first only had BSOD when using Google Chrome, but it has now occurred in games too.

The specs of the PC are:

Core i7 4790

EVGA GTX 960

16 GB RAM, DDR3 1600 for both kits in there. The stock is 1.5v and what I added was Crucial brand at 1.35v according to HWinfo. They are all running at 11-11-11-28 timings.
The stock sticks are SK Hynix HMT351U6CFR8C-PB and the new Crucial sticks are Crucial CT51264BD160B.C16F.

Corsair CX650 PSU

1TB hard drive

Any help to fix this is greatly appreciated!

Thanks.

I will try running the system with the original 8 GB and see if it goes away. I'll update with results.

Ok after a good amount of time in Chrome with the original 8 GB, no BSODs of any kind.

With only the new modules installed in the same slots as your originals, run memetest86 from a flash drive to test the modules for errors. If you get errors, you should return them for a refund or replacement. You may also want to consider getting a 2x8GB kit as your motherboard supports 32GB over 4 slots. https://www.memtest86.com/

Two other issues may be the problem. The first issue is that mixing your different voltage memory kits, while it should work fine, may be incompatible as they are not a single kit. The other issue could be you need to reseat the CPU by taking it out, checking for bent pins in the CPU socket and then placing the CPU back in and repasting it. Sometimes movement or the case getting hit can shift the CPU or socket pins and cause memory slots or the system to stop functioning properly.

Use of multiple kits of memory have no guarantee to be compatible together.

You can make any kind of combinations you want and do your own compatibility testing with no guarantees if thats what you chose to do.

I used Memtest on the new sticks and they seem fine. I've been running the PC with just the new sticks in, and it has had no problems. I think it's definitely an issue of mixing kits, so I'll probably end up ordering another 8 gb of the same stuff as the new sticks. Thanks for the help!
