If I have 4 ram slots on my PC, and I fill 2 slots with 8 gigs each, and 2 slots with 4 gigs each, how much memory would show up on my PC?

The details are in the question. I'm wondering if my PC will think all the ram slots contain 4 gigs, or give me the total ram I've installed?

    It won't think 8gig modules are 4 gig, but the bios may or may not not accept mixed modules. I use the scanner at Crucible.com to check.

    24gb of RAM should show up

    The Slots should be color coded, but not always. 

    Typically you would install 4gb, 8gb, 4gb, 8gb. 

    Typically first 2 slots are Channel A and the second two slots are Channel B. So you want to mirror/match each channel.

    Depends on the motherboard, but usually, pairs need to match but not all 4.  Each set of pairs can be their own thing. So you should see (8 + 8 + 4 + 4 =) 24 GB total
