HP PROBOOK 450 - DDR3 MEMORY TYPE NOT SUPPORTED

[DucHuuNguyen]

I've bought a HP Probook 450 recently. And I upgraded the memory from 4GB to  8GB. I added a 4GB DDR3 Samsung 1600MHz PC12800. But when I start the laptop, it shows error "DDR3 memory type not supported. And it said I should remove the added RAM.

I don't know why I meet this issue although my new RAM has the same tech specs.

What type of RAM should I buy? Or what should I do in order to prevent that error when I startup my laptop?

Thanks for any help

It uses DDR3L (low voltage 1.35 volts) and you may have tried to install regular 1.5 volt DDR3. If this is not right then please provide us will as much information as you can (from the label) on the memory you have added.

Thanks for your response.

I don't think it's a DDR3L b/c my CPU is an Ivy Bridge one, not a Haswell. I heard that only Haswell uses DDR3L. Here's the original and added RAM of my laptop.

BTW, my another laptop has the same configuration: Slot#1 is 1.5V and Slot#2 is 1.35V but it works fine

It will take a while for your pictures to pass the censors. The Service Manual definitely shows it as DDR3L and a 3rd gen (Ivy Bridge) CPU:

See pages 1 and 2.

Yes, I see it. I think I need to find another RAM.

Thanks for your help 🙂
