NEED HELP. My ram is running at 1800 MHz on a Hp all in one

[DHurtado714]

I just upgrade my HP pavilion all in one 24-r028la, with a DDR4 4GB stick at 2400 mhz (both sticks have the same speed and memory). However, both sticks are running at 1800 MHz and I can't change these settings in the BIOS. If anyone knows what to do, please tell me, I'm desperate.

What are the full specs of the machine? The issue is probably that one of your components (CPU or Motherboard) doesn't support 2400MHz RAM.

Having the same speed is not the only thing required in ram. The timings and the maker of the chips on the ram also affect. Using auto to set the speed won't work, you'd have to manually set to the timings of the slower ram stick./

These are the system specs.

 

It came with a 2400 MHz stick.

 

It also says that DDR4 Ram at 2400 Mhz are compatible.

There both the same speed. I can change the speed at BIOS. HP BIOS on All in one's is garbage

There are very very few all-in-ones that aren’t garbage.  They exist, but they’re rare. An all-in-one not infrequently is the equivalent  of a desktop replacement laptop glued to the back of a monitor.

What are the CAS timing specs for each stick?

What tool / program are you using that it is showing 1800 MHz?

As far as I know, DDR4 JEDEC standard is DDR4-2133 minimum, so I don't see how you are getting 1800 MHz (I'm assuming actually 1866 MHz).

 

I would say use something like CPU-Z, and check the MEMORY tab.

If your memory is running at 2400 MT/s, it will show up as ~1200 MHz in the DRAM Frequency box.

No idea

 

This is the ADATA stick on socket 1 am1p24hc4u1-b9rs

And this is the Samsung stick on socket 0 https://www.samsung.com/semiconductor/dram/module/M471A5244BB0-CRC/

I used task manager, BIOS and system diagnostic.

 

In CPU-Z is 931.4 MHZ

It says on CPU-z 13 clocks

[Aree Soothsayer]

Try checking with thaiphoon Ram checker.

 

Edit: I say this because it shows your current cas for it's 1800, not the boosted numbers. The program will read the embedded data for each ram stick allowing you to compare those values.

Are you able to provide the CPU-Z information for the two sticks of memory?

Post the screenshots here.

 

For example...

Slot #1  , Slot #2

  

 

If you have no control over the DRAM frequency setting in the BIOS, then HP has locked that setting out in their custom BIOS firmware.

It basically runs on auto, or under HP's own rules.

 

Has the memory EVER ran at 2400 MT/s, or you just noticed this now, when upgrading the memory?

 

 

EDIT:

Did a little bit more digging...

Certain models of APUs from the 7th Gen A9-series supports only UP TO 1866 MHz.

Not all of them does up to 2400 MHz.

Its a A9 9430

 

Is the first time I am concerned about the ram speed. I can select each module, but I tested individually and they both ran at 1866 MHz.

 

If you know to unlock this feature on the BIOS I will appreciate a lot

old AMD.  My memory is those were famous for being extremely persnickety about memory.  So much that the QVL list actually became important again.  I may be only thinking of first gen ryzen though which that predates.

No, unfortunately, that is nothing I know how to do.

I tried to find a way for an old Acer motherboard (AMD socket AM2 days), but no luck.

 

You basically need to "hack" the BIOS code, and re-enable it -- if it is hidden.

If HP completely removed the option, then...that's a little more difficult.
