I've recently bought 4 new sticks of ram but I can't use all 4 together. I can use 1 or 2 but it usually pops up with a boot failure which I most of the time I skip over. But when I use all 4 sticks my pc fans don't light up and I get a couple of long beeps. I originally ran 128GB over 4 sticks and used 16GB over 2 sticks as a placeholder until my new ones came. I've got a Gigabyte Z690 Gaming X DDR4 motherboard if it helps.
