Hi,

I've little problem, that my 6x4GB (Corsair Vengeance) shows up as 16GB of ram for BIOS.

First I thought that maybe there's fault on my MB memoryslots, or in memories. But sometimes BIOS shows that it finds 24GB of ram, but mostly 16GB. Funny thing is, that even that BIOS detects 16GB of ram, CPU-Z finds 24GB of RAM?

I tried to search similar problems from forum, and maybe the closest was this:
http://www.tomshardware.co.uk/forum/308873-30-24gb-asus...

Couldn't find "Memory protect"-option from my BIOS, so could it be something else?

Operation system is 64-bit Win7 Ultimate, so it shouldn't cap it.

Thanks for answers!

Have you tried cleaning and rotating the positions of the modules? something similar happened to me not long ago and that fixed it...

Tried to swap all modules in new places 6->1, 5->2, 4->3, 3->4, 2->5, 1->6, and got now 20GB show up.

So maybe there's some dust or something in slots (that were open before memory upgrade). Have to buy some compressed air cans to blow slots clean from dust.

It's funny that BIOS doesn't detect 24GB memory, but CPU-Z does... How's that even possible?

Pick up can of contact cleaner along with your compressed air .
Spray the cleaner on the ram contacts ,wipe away any excess then seat into motherboard.

I think it seems to be one ram-slot broken, because event with lot of compressed air, whole bunch of contact cleaner in ram-slots and ram-modules contacts, getting 20GB visible memory. Looks like C2_Slot isn't working, because it doesn't matter is there ram-module installed or not...

Maybe I'll just update my whole setup, (as I've should done a year now), and send MB in to warrantyservice (still two months warranty left). Maybe I could get a new one! :)

Check the cpu contacts on your motherboard. Maybe they is corrupted
