Maybe one of the sticks is dead, try taking them out one by one (how many sticks of what capacity do you have? On what motherboard?)

Disable your iGPU in the BIOS, for starters.

What are your specs? Are the sticks of RAM you are using all the same?

I'am sorry but what does the iGPU has to do with the RAM Memory?

So I'm assuming it's special RAM, first of make absolutely sure all sticks are properly connected. Then test each individual stick and slot.

the igpu uses system ram as its graphics memory.

try pulling that one out and see if it stays the same; if it does that stick is incompatible with the others.

some of the system ram gets allocated to the igpu, so it may be the problem.

The iGPU uses RAM in place of dedicated VRAM.

1. Click Start, type msconfig in the Search programs and files box, and then click msconfig in the Programs list.

In the System Configuration window, click Advanced options on the Boot tab.

Click to clear the Maximum memory check box, and then click OK.

Restart the computer.

I had 16GB of same sticks before, last 2 days but the iGPU does not use it as it's Vram because i saw it was fully 15.9GB usable on the windows. how come now it is using it?

1. Click Start, type msconfig in the Search programs and files box, and then click msconfig in the Programs list.

It's fixed, turned out somehow it was on 0 memory, and even processors was 7.. i have unchecked "Number of Processors" and "Maximum Memory" now it's all fine. Thank you bro, And thanks to everyone here who tryed to help really awesome community ! love you all (NO HOMO) <3
