Review on 🔥 Corsair CMK32GX4M2A2666C16 32GB DDR4 Vengeance LPX Memory Kit - 2666MHz, PC4-21300, (2x16GB) - Black by Jamie Smith

I made the mistake of adding these two sticks to another set (same make/model) to install. Somehow it broke my machine so much that I had to reinstall Windows. I have no idea how my C: got corrupted by this, but I lost my SQL database and had to spend about 4 days reinstalling programs and then recovering my database. It happened that my mainboard only recognized 2 sticks at first. Then two more came along, but all of the RAM ran at a much slower speed than it should have. Profiles in the BIOS were not filled out correctly. Windows kept getting repaired on startup and eventually crashed completely. Generally, RAM is sold in kits that are factory tested to ensure they all work together. It is usually possible to add two more cards of the same make/model as they should have the same timings but this is not always guaranteed as I am sad to learn they come in factory tested kits. got them to work with my old sticks. I just had to update the bios. Asrock apparently recently released an update that increases RAM compatibility. I didn't think it would matter considering I already had two sticks of the same material, but it did. If you are thinking of purchasing them as an upgrade and you already have one, please update your BIOS before making the same mistake I did.
