Hardware New RAM not detected

[antiNT]

Hello guys, so today I wanted to install a 4gb ram onto my asus laptop (x554l)
The RAM was bought here: http://www.cdiscount.com/informatiq...ProductsApi&InteractedPlacementId=Internal_SP and now my computer starts normally but when I check in Task Manager it only show 4gb.

What can I do?

Installs 4GB of ram and complains there's only 4GB???

I really don't understand.

Sorry i forgot to mention that i already had 4gb now it should be 8gb

 

[mechagouki]

I'm guessing you have added 4GB to an already installed 4GB ?

Are you running a 32bit (x86) version of Windows? it will fail to address >4GB. other than that, make sure it is installed correctly and try again, check the latency is the same.

Does it only has 1 ram slot.

I am running a 64 bit version of Windows 8 and yes i have added 4GB to an already installed 4GB.

I did not removed the default one and yes my laptop has 2 slots.

Look in the Bios (Uefi) if the Bios (Uefi) detects it.

Look in the Bios (Uefi) if the Bios (Uefi) detects it.

In addition, try memtest.

note: if this is a BIOS based system it may not detect the extra RAM like with one of my old laptops.

edit:

Have you tried swapping the RAM around to see if it might be the slot?

Look in the Bios (Uefi) if the Bios (Uefi) detects it.

How can I do that?

 

[DarkGabbz]

Look if the ram sticks are right in the slots because it detects only 1.

Can you post some more system information, e.g. model and CPU?

 

[Joe88]

I think it only takes ddr3l ram

Ok so it's an Asus x554l laptop Intel Core i5 5200U with 4gb ram and an NVIDIA GeForce 920m GPU

If it was the case my system won't boot right?

 

[GerbilSoft]

Not necessarily that it won't boot. In this case, it's entirely possible that the memory controller just "gives up" on the second module and continues booting with only one.

Can you get the model number of the working module?

 

[antiNT]

Sorry but what's the module? My laptop is special since the first ram is soldered to the mother board. I followed this video to install the RAM :
I just removed a little cover

 

[GerbilSoft]

So it isn't actually two slots; it's 4GB built-in, plus an extra slot.

I'd say the most likely issue is the fact that your laptop does need DDR3L (1.35V), but the module only supports 1.5V. See if you can get it tested with a known good DDR3L module to make sure that this is the problem instead of there being something wrong with the slot.

That's the only RAM i have, i just tried removing it and re insert it and that did'nt work. But, now that I know it don't work, should I leave it in the slot or remove it?

Did you even look at the BIOS and the RAM voltages? Asus probably hard coded the BIOS to only accept DDR3L RAM. It's pretty common in ultrabooks. In that case you bought the wrong RAM.

It's the first time i do this, can you please tell me how to check the BIOS?
