Asus P6T motherboard won't detect my full ram

Hi,

I bought some years ago an Asus P6T motherboard. Now I tried to seat in 4 x 4gb (for a total of 16gb) of Corsair PC3-10700H (1600mhz), but the motherboard only sees 8gb, so just half of it.
I read the manual and chose the right configuration for the DIMM slots, so it's not a matter of wrong positioning anymore. I just updated the BIOS too, but it didn't do anything to help.
It's like the motherboard is reading my 4gb sticks as 2gb sticks. It should be 4 x 4 = 16gb, but right now is 2 x 4 = 8 gb.

I've tried to solve this problem to no avail for some days now and I really don't know what else I could do or try.

Any suggestions?

So starting from the CPU, going to the edge of the board it's

4gb
4gb
empty
4gb
empty
4gb

Right?

Is it just windows where it's not showing? Can you see all 4 sticks in BIOS?

Check under boot in msconfig, do you have 'maximum memory' ticked at all?

Asus boards are funny for ram, push the side in where the lever doesn't move first, then do the locking side.

- Yes, I inserted the ram just like that.

- My Windows 7 Enterprise (which has a 192gb memory limit or something like that, so I'm not memory-capped) shows 8gb; even BIOS and CPU-Z show a total of 8gb of ram.

- I checked under msconfig and I haven't the maximum memory ticked at all. Should I tick the box?

I've already tried reseating the ram multiple times: it's placed well, like the method you explained, locked and loaded and tight!
Hehe I'm starting to lose hope.

I'd like to trash this motherboard in the garbage bin right now, but my cpu—which still is quite decent—unfortunately uses a 1366 socket, and it's rare to find motherboards compatible with a 1366 socket in 2014.

It would be expensive trash, the mobo is worth more than your CPU right now lol. Besides, 8gb ram is enough for almost anything :) 

Don't tick the box in msconfig, leave it unticked.

Did you buy it as a 4 piece kit, or 2 packs of two?

Handle the ram carefully when you do this
- Test each stick individually in slot A1, one at a time
- if they all work successfully, take one stick and try it in every slot one at a time
- Assuming you've done this then you'll know that every stick and every slot is fully functional and shit gets a bit harder...

I also own a P6T but I'm only using 8gb, so I've not tried more than two sticks at a time.

Actually looking at the manual you can only try single stick boot in A1, B1, C1 - to test A2, B2, C2 you would have to try it in pairs (A1+A2, B1+B2, C1+C2)

I bought the RAM as a 4 piece of kit, if my memory serves right.

Heh, shit's getting harder by the way ;)  I tried and tested every stick and every slot yesterday. They all work, but each stick of ram gets recognised as a stick of 2gb—and that's the main problem, because my sticks are 4gb! :D 
I don't know if it matters, but on each stick there's written "2x2 4gb ram".

If I could get it to recognise each stick as a 4gb then my problem would be solved.

Hmm, maybe it's treating the double sided memory as single sided? curious, I'll do some digging...

can you give me the part number of the ram from cpu-z? (under 'SPD')

There's your answer. Each stick is actually 2gb, not 4. What you have is two 2x2gb kits, hence why 4gb is written on the labels.

Ahh! That explains a lot.
That label thing was quite misleading though!

Mystery solved: I need to learn how to read labels! :D 

Thank you for your time, Luco, you'll be my best man at my wedding!

It's a bit cheeky writing 4gb on the label really, I understand the confusion. Luckily 8gb is plenty :D 

The p6t overclocks like a boss, I currently have an i7-930 @ 3.8ghz and it will go further for sure, maybe one day i will test how far...
