New ram, pc doesn't boot

Hi,

I already had 2x4 gb dimm's from patriot and decided to upgrade it to 16gb so i bought another kit that is exactly the same.

I put it in and my cpu cooler lights up and my fans start spinning but i don't get display output.

I removed the new sticks and everything worked fine again. I restored my ram to stock settings and put the new dimms in again. Nothing. I removed the two old sticks and like magic everything works. The problem is that everytime i put more then 2 dimm's in my system i don't get display output. My motherboard is the msi x470 a pro and my processor a ryzen 5 2600x.

Frustrating, RAM can be finnicky. More frustrating how much people will tout "just fill up two slots so you have an upgrade path later"...unless the identical RAM sticks you buy later were updated by the company in some way making them incompatible.

I have 2x corsair LPX sticks in my intel rig, went to double the capacity and buy two identical sticks (same brand, mHz, everything). Plugged them in and at first would never boot. Finally after 4 attempts it worked but then was super unstable. Took out new sticks, reset everything to stock, disabled XMP, back to working. Tried the new sticks again and same issues, programs randomly crashing, BSODs, super annoying. The new sticks do work on their own. I ended up throwing them in my ryzen rig because that one could utilize them well and was an upgrade from what was in it. But very frustrating that it isn't just a plug and play situation. I will probably have to just replace the kit in there right now and get 4 DIMMS that come in the same pack
