Minecraft thinks I have 4GB of RAM, but I have 16.

So today I changed my case for my PC, upgraded to an NZXT H440. First of all, when I got it to post, the bios said I had 16GB of RAM which is correct, but it said it was 1333Mhz when my RAM is actually 1866MHz. I said whatever and booted into Windows 10. I then tested my system on Minecraft to make sure I was achieving the same performance. I used to get about 140fps on extreme render distance (using optifine) but now I get anywhere between 40-80 fps on the same settings. When I pressed F3 to check my fps I noticed that it said I have 4000MB RAM total and 1000MB allocated. I actually have 16GB and I have it setup with 4GB allocated.

I don't know if this is a RAM problem or a Minecraft problem... Anybody know how to fix this? preferably without buying new RAM. Also why did the bios say my RAM was running at 1333MHz instead of 1866MHz.

Nha 4 is fine xD, or if you want to have allot of exploding TNT you need 16, but if you want to see if your ram is installed correctly, look it up in task manager at ram usage if it displays 16.
