Can I have 1 memory slot DDR3 and another DDR3L?

[jtsmartins]

Hi experts,

Can you tell me if it's possible to have one slot with 4GB DDR3 RAM and another with 8GB DDR3L RAM (same frequency)?

I've seen it working in my PC, but the DDR3 slot is with 1.5V and the other with 1.35V, so I removed the DDR3 and I'm only using the DDR3L memory, but it would be great to have 12 GB! 🙂

Whit best regards,

Yes you can add another 8gb memory on the unit as the unit supports upto 16GB of memory on it.

You can use the part number 670034-001 which is an 8GB memory module which is supported for this unit.

Hi @Zoan,

Thanks for your feedback.

Sorry but I think my question wasn't that clear.

What I would like to know is if I can have, for example:

Slot 1:

DDR3 4GB 1600MHz - 1.5V

Slot 2:

DDR3L 8GB 1600MHz - 1.35V

I already started the PC with this config and that was when I've seen the voltage difference. So I would like to know if DDR3 and DDR3L can be used at the same time or if the board can't handle this config and this can destroy one of the memories (or any other component).

Thanks and regards,

JT

Hi all,

My DDR3L is a dual voltage RAM so it will support 1.35V or 1.5V.

From my investigation mixing DDR3 with DDR3L should not cause any problem. What should happen is that the dual voltage RAM will work at 1.5V instead of the low voltage value. But if anyone wants to have the RAM working at 1.35V then both RAMs should be DDR3L and the motherboard should accept DDR3 and DDR3L.

I don't know how the tool that I've used works(CPU-Z), because from what I've found in my research both voltages should be 1.5V and I'm seeing one at 1.35V and the other at 1.5V... but this could be a problem from the tool that is only checking the lowest voltage from DDR3L RAM instead of the real used voltage.

Thanks you all for the support, I will close this topic now and hope this may help someone in the future.

With best regards,

JT
