Enable Dual Channel Memory Support on HP X360 13"

[davipiero]

Hi.. Good Morning.

First of all here is my laptop information:

HP Pavilion 13-a048ca x360 Convertible PC
Serial Number     :   [Personal Information Removed]

Product Number:   G6S98UAR

I have installed a new 4 Gb memory with same spec and brand with the pre-installed one. By the way here is the complete information of my memory as taken from HP hardware check utility:

DIMM:                                    Device Locator         Bottom-Slot 1 (left)

(preinstalled)                     Manufacturer            Kingston

                                                Serial Number           [Moderator Edited Serial Number

                                                Memory size               4096 MB

                                                Memory Speed          1600 MHz

                                                Memory Type             DDR3

                                                Type Detail                  Synchronous Unbuffered (Unregistered)

DIMM:                                    Device Locator         Bottom-Slot 2 (right)

(new)                                     Manufacturer            Kingston

                                                Serial Number           [Moderator Edited Serial Number]

                                                Memory size               4096 MB

                                                Memory Speed          1600 MHz

                                                Memory Type             DDR3

                                                Type Detail                  Synchronous Unbuffered (Unregistered)

 A software called CPU-Z still tells me that #channel: single. In fact i have installed a new memory with same spec and same brand, haven't I?

Then, i browsed around and found the following documentation:

HP Pavilion x360 Convertible PC Maintenance and Service Guide

Looking through that document i found the following:

Memory: 2 SODIMM slots DDR3L-1600MHz

Support for DDR3L-1600MHz

Support for dual channel

Supports up to 8096-MB maximum on-board system memory

Back to my laptop, I'd like to know how to enable dual channel memory support in my laptop? Can it be done? And how to check accurately afterward to confirm it?

Looking forward to any solution available.

Thank you.

The memory modules have to be absolutely identical in every respect. The best way to make certain of that is by installing two identical guaranteed compatible memory modules.

The BIOS takes care of the dual channel configuration on its own. 

There are no settings available in the BIOS for you to do that on your own.

Here is the memory specs that i retrieve from CPU-Z, please take a look. Does it seem to be identical 2 pieces of 4 Gb Memory?

How do i enter BIOS in my laptop by the way? F2 when booting takes me to HP hardware check utility instead.

The part numbers shown in CPU-Z are different for the two memory modules. 

Press the power button and then  begin tapping the F1 key to invoke the BIOS.

Part number? hhhmm.. allright then, i guess i should buy it also from hp store to get the memory with part number started with HPxxxxxx.

Thank you very much..

F1 takes me to the system information only, not to BIOS

[erico]

To invoke  BIOS on HP desktop and laptop PCs the F10 key is what should be used. 

The F1 in my last post was a typographic error that I did not catch before posting.

Hi, here i am again with some updates.

So i have bought another kingston memory, this time i bought the identical twin of the previously i bought.

Check it out in the picture below, the RAM beside the packaging is the original RAM pre-installed inside the laptop.

Now, i have two exact same memories installed. 2 x 4 Gb

Here is the ss from CPU-Z, now the part number is also the same between those 2 memories:

But. the sad part is my laptop is still running in single channel memory mode 😞

Here is the ss from CPU-Z:

I'm running out of ideas why it is stil in single channel, is it the BIOS? is it the motherboard? or else?

The documentation said it supports dual channel memory.

Please, help me..

According to the Kingston Memory search that I did, It seems that only the following memory modules are guaranteed compatible to your notebook. Note the part numbers and the Important section to the upper right. Where did you find the part numbers for the ones that you bought?
