8gb 1600 corsair vengeance - windows showing 8gb (7.89 useable) - normal?

Thread Starter 
Just finished a new build and windows is showing that I have 8gb of ram installed, but only 7.89 is useable under system information. Is this normal?

Yep totally normal. Kinda like if a HDD is 1TB, technically there is like 998.4GB usable or something along those lines.

In most installations it's because either the BIOS or one of your other hardware devices has reserved the memory. As Evilsplashy said, it's totally normal behavior. I have 16GB in mine with only 15.9GB usable.

Here's the M$ article explaining it in more detail
