Hello,

I have a Latitude 7300 with 16gb of ram. Back in June I added an 8gb Crucial stick for a 24gb total.

For the first few months everything worked fine. However around a month ago the screen suddenly went black and the laptop stopped responding and could not reboot. After removing the extra stick it started working again.

I tried both ram sticks separately in each slot and they both work fine. But as soon as I put them both in, the PC doesn't boot and I get flashing led lights indicating incompatible ram.

I would really like to use dual channel memory.

How can I solve this ? Why did it work fine for almost four months?
