Max memory supported HP Gaming Pavilion - 15-cx0051ns

[miguel84]

Hi

I have a Pavilion - 15-cx0051ns with Intel HM370 chipset, I currently have 2x4GB 2666Mhz CL19

Between 3200 CL22 vs 2666 CL15, which would be better performance?

Also, what's the maximum amount of GB supported?

Cheers

Hi:

I can't find any specs on that model.  What processor does it have?

i7-8750H

Hi:

The max memory is 2 x 16 GB for a total of 32 GB, and the fastest speed would be what you have in there now --  2666Mhz .

3200 MHz memory would just downclock to match the processor's FSB speed of 2666 Mhz.

You're very welcome.

 So I went and bought this

Crucial Ballistix Sport LT BLS2K16G4S26BFSD Laptop Gaming Memory Kit 2666 MHz DDR4 DRAM 32 GB 16 GB x 2 CL16

But the clock speed says 2400Mhz

Is that normal?

[Paul_Tikkanen]

According to chapter 1, page 1 of the service manual, the memory is supposed to run at 2666 Mhz with the processor your notebook has.

Two non-customer-accessible/upgradable memory module slots
DDR4-2666 dual channel support (8750H/8300H processors)
DDR4-2400 dual channel support (8550U/8250U processors)

Why is isn't unfortunately that I do not know.

Found this online:

"However this computer does not have the ability to run Intel XMP settings so it is down-clocked to 2400MHz instead of the advertised 2666MHz. "

Something I can do to overcome this?

[Paul_Tikkanen]

Unfortunately, that I wouldn't know.

Did the original 2666 MHz memory module run at 2666 MHz?

I suggest you start a new post regarding that subject.
