So recently I got 2x4GB sticks of RAM. One of them is made by Corsair and the other one by A-RAM. I installed them on my dad's PC and it would fail to boot to Windows. Although the PC still picked up 12GB of RAM. It would tell me a recent software or hardware change might have caused this and it gives me 2 options: Fix the problem or Boot normally. Either one never works and just freezes and the PC would just re-boot. Then I tried installing it on my PC and the exact same error occurs. I went from 1x4GB stick + 2x2GB sticks to 3x4GB sticks. I tried swapping them around on both systems and it didn't work. I tried removing 1 stick and it still wouldn't work. IDK if this matters or not but my dad accidentally removed the stickers on both sides of the Corsair RAM and the Corsair RAM has chips on both sides of the RAM and the others only have chips on one side. Right, I just tried booting without the Corsair RAM and I successfully booted to Windows. I'll pop over to my dad's and pick up 2x2GB sticks of RAM and see if I can get 12GB going. If it does work, I'll return the Corsair stick.

Usually you have to be careful when matching up ram...same voltage spec...same cas and similar frequency. Mixing sizes and types can cause problems. Are they all 1.5 volt ram?

You also have to populate the dimms in pairs

You have 4 Mem slots you need to run them in pairs not the first 2 and the 3rd wonder it boots now I would keep the corsair ram I am sure the A-ram is probally the problem plus the timeing between all the mem sticks are probally off. Its always best to buy ram in pairs and the same or equal values that's why the windows error is popping up.
