ASUS N56VZ bsod with 16 GB of ram.

After reading the 16gb ram thread on this forum, I purchased the Corsair 16GB Dual Channel DDR3 SODIMM Memory Kit (CMSO16GX3M2A1333C9) from Amazon. I didn't have any trouble booting the laptop, but I had frequent BSOD's related to ntoskrnl.exe. I ran MemTest86+ overnight for several passes and no issues were detected with the physical ram itself. I began using a single stick of 8GB from the kit instead of both sticks of ram. I haven't crashed since, but I was hoping someone would be able to identify the cause as to why. I spoke to ASUS support and was told that the laptop does support 16GB of ram, but I'm confused as it to why the laptop s itself when I run it with both sticks, rather than just one 8gb one. Thank you to anyone who reads this.

Edit: I'm running Windows 8.1 on my laptop, freshly installed on a Samsung 840 EVO SSD.

 

What brand of memory was in the laptop originally? It's generally not ideal to mix different manufacturers memory.

 

These were the original 4x2 of 8GB ram that I was running on my computer. These work fine, and right now I'm back to using these. I have not had any BSOD's or crashes since. I bought a pair of these, each 8 GB. I read the lengthy 16GB Ram thread, and thought this to be the best 16 GB ram kit to use for my laptop. Unfortunately it's causes me crash often. Thank you by the way for replying to me, I really could use the help.

 

Seems like the mixed of RAM caused a mix of different frequency and timing values together and caused the BSOD.
Corsair ValueSelect CMSO16GX3M2A1333C9 is 1333MHz, CL9, 1.5V.
Crucial CT51264BC160B is 1600MHz, CL11, 1.5V.
SKHynix HMT351S6CFR8C-PB is 1600MHz, CL11, 1.5V.

You should exchange your ValueSelect to 1600MHz/CL11 to allow the same speed/timing during operation.

 

I'm sorry but I don't understand. I'm not mixing the corsair kit with the other two ram. The Corsair Value Select is a kit of two 8GB. Are you saying that the laptop specifically needs 1600MHz CL11 ram?

 

Whether Asus or the supplier, you should not have received mixed modules in the first place. You can often get away with it, but for quality assurance sake, it's far and away considered better practice to match brands and models of memory modules.

As for the Corsair, if you're getting BSODs off running those two modules, then one or possibly both of them could be faulty.

 

I agree, try running each stick by itself to see if it has issues.

 

Try one at a time and use memtest from Memtest86+ - Advanced Memory Diagnostic Tool to verify integrity.
If both sticks are fine but not when used together then it's compatibility issue since CL9 might be too aggressive, then exchange to 1600 CL11 modules instead.
