DDR3 Ram Slots STD VS BTM

[Froggyking1]

I'm trying to upgrade My DDR3 Ram from 4GB to 8GB. I only Have two slots on my motherboard, on one slot it says STD and the other slot it says BTM. When I put a Ram into The BTM slot it feels to tight, it does not fit in smoothly, the clips that hold the ram down looks a little larger too and the system will not boot with Any Ram in The BTM slot at all. I looked up my system ( Acer Axc-603G-uw15) it says it needs SODIMM but the ram that was in it from the factory says DIMM. Will a 4GB SODIMM fit into that BTM Slot. please help

Which make and model of the RAM are you trying to install?

To install SODIMM, you will have to grab the module and put it tightly in the slot at an angle of about 45 degrees, then push it down.

update the BIOS to get it compatible with newer memory modules, version P11.B4L is the latest:

As I could see in google, it uses 2 sodimm modules (notebook ram).

yes, it´s both SODIMM DDR3, but couldn´t verify the compatible voltage (DDR3"L" = low voltage = 1.35V or DDR3 1.5V)
This has to be labeled on the RAM itself. Post the complete model number of the one, which was installed in the system before.

Difference:
SODIMM 204Pins
and DIMM DDR3 240Pins

you can´t accidentally put a normal size DIMM into an SODIMM slot
