Two Different Rams Incompatible || How to Fix?

[AdaAC]

Hello! I recently got my computer "fixed" cause my previous 8GB Corsair Vengeance RAM stopped working, or something like that.

So at a shop, I got it replaced by two modules of 8GB, poccessing now 16GB of RAM. However, even though they are both DDR3 and the same brand ADDON, one is smaller in height than the other. Why do I mention this? I have been having a LOT of crashes with a BSOD saying "Memory_Management" to which I proceeded to take 1 ram out and do my daily stuff with such, see which ram is the bad one. However, The computer works perfectly well with each one of them alone, which led me to believe the issue is they are not compatible together.

My question is, can I somehow fix that on my own, or do I have to return them and get 2 modules exactly the same to the dot?

Thank you for taking the time to help me.

Mixing RAM, even of the same size and manufacturer, sometimes does not work.

The 'shop' should have verified full working condition before they gave it back to you.

They need to be exactly the same, and the fact they gave this PC back to you with RAM like that speaks volumes about the "quality" of their work. Go back and demand they put matching memory modules in.

Alright, so I can't fix it, need to get them equally the same. I'll do that, what if they say that the warrant to change them is over? I think it was 7 days or 15, and it's been 7 days+

You did the work, troubleshooted, and found the answer. It sucks, but yeah, buy a matched pair. Maybe you'll get luck at "the shop" if nothing else he or his customers should know matched pairs have been standard for over 10 years.

You paid for a non-working system. They need to make it right.

Now...given their apparent lack of clue, I fully expect them to push back on fixing it properly.
How things go after that all depends on how hard YOU want to push them.

No matter what the outcome, never go there again. And tell your friends the same.

What are the model numbers - while best to have them 'fix' the problem they created - if they don't can try initially raising the DRAM voltage + 0.05 to try and stabilize. If no joy there also provide what CPU and mobo.
