Unsure about supported memory frequency - HP ProBook 430 G5

[gasiho]

I want to upgrade the memory of my HP ProBook 430 G5 but reading the specs has left me uncertain of what memory speeds are actually supported.

 

The sticks I am looking at buying are these: CT2K16G4SFD824A

The current stick is called Micron 4GB 1Rx16 PC4-2666V-SC0-11 (can't find official specs)

 

Excerpt from BIOS:

Processor Type: Intel(R) Core(TM) i3-7100U CPU @ 2.40GHz

Processor Speed: 2400 MHz

Memory Speed: 2133 MHz

 

Interpreting the product name, it looks like the currently installed stick supports 2666 MHz (???) but when installed in the laptop they're forced to 2133 MHz.

 

But the HP specification states:

• Maximum | 32 GB DDR4 - 2400 SDRAM
• Standard | DDR4 PC4 - 2400
  • note: System runs at 2133 (Intel 8th Gen CPU runs at 2400). (2) SODIMM slots supporting dual-channel memory (both slots are customer accessible/upgradeable)

 

The CPU specification however says nothing about 2400 support:

• Memory Types | DDR4-2133, LPDDR3-1866, DDR3L-1600

 

Should I expect a pair of 2400 MHz sticks to be forced down to 2133 MHz as well?

Can I trust the HP specs that mention 2400 or should I listen to Intel specs and buy 2133 sticks instead?

 

Grateful for any advice.

I think you can trust HP...but then...i also think its better to stay on the safer side

 

I mostly think the mobo's bios will downclock the RAM after installation to get 2133mhz

Max supported memory speed is 2133MHz on 430 G5 with a 7th gen CPU, and 2400MHz with a 8th gen CPU. If you have a 7100u it will not run at any faster than 2133
