Pavilion - 15-cx0051ns

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:

 

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?

HP Recommended

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.

HP Recommended

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?

HP Recommended

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.
