[SOLVED] Windows doesn't see upgraded RAM

[bkvstar]

I have recently filled my RAM slot with a new 4GB RAM Card but Windows doesn't see it(it still reports only 1/4 slots filled and old amount of RAM). The weird part is that CPU-Z sees the new card and gives me all the info about it so I think it's not a hardware problem. I have updated my BIOS without any changes. Both cards run on same frequency. Any solutions or suggestions?

What's your motherboard and dimm slots used?

List PC specs including memory modules please.

Is this enough info?

Is this for a desktop or laptop? I assumed it was a desktop being that 4 slots was mentioned, but searching Lancer 5a5, can only see a motherboard belonging to a laptop.

Yeah it's a laptop. It says 4 slots but I think it has only 2 slots physically, at least I can't find more slots inside. I had that issue on multiple laptops, the number of slots it shows is connected to something else, not physical slots on the board.

What laptop model is it?

Ok think i see the problem. The laptop requires 1.35v DDR3 L ram. One stick is 1.35v and the other 1.5v in slot 1.

Cpuz will still register it's there but i believe the motherboard is restricting use of the dimm slot 1 to prevent damage to the cpu's memory controller running 1.5v ram and that's what Windows see's.

I see. I noticed the difference too but didn't know if that's the problem. I'll try to get DDD3L RAM and so if it works.
