Hello, I just bought 4 x 8 gb 3200 MHz Corsair DDR4 DRAM to replace my 2 x 8 gb 2666 MHz UDIMM.
I have an I-9700 CPU and that's why I expected my new ram to run at 2666 MHz. But it runs at 2133... I understood that I could change the speed in BIOS, but I can't click on most of the things there. Something I can change but amongst other things I can not click on or change my memory.
the BIOS is called American Megatrends Inc. R01-B2
I have a predator PO3-600
Does anyone know what I can do to increase my RAM speed?

Yeppoon, QLD, Australia.
the motherboard is the deciding factor in how memory pans out.
check the mobo's memory compatibility list for those memory chips.

I thought 3200Mhz was only achievable with the XMP over-clocking profile setup in BIOS. (but I admit, never OC'd before)

the things you can't click on now in BIOS, could you when you were using the old RAM?

Hello Bruce, I can't click on anything else with the old ram either.
this is how it looks like, I can only click on the the blue words, not the grey.

What is the make and model of the mother board?

Are talking about grey out like on this screen here correct? That is strictly information and not anything that can be changed.

You may need to refer to the manual to see if that can even be done with the BIOS you have. Look for something that is called XMP options like Bruce stated. You may need to refer to the manual which is why we are asking for the make and model.

Hello Rustys, i think i start to see the problem, i found the manual and it says i have to use Acer approved DIMM ram, i got corsair DRAM ram. And the BIOS looks pretty much like the picture, I cant do anything with the grey things. thank you for your help. Do you think that is what the problem is or something else? and i didnt find anything about XMP.

If you put back in the original RAM does the system run correctly and show in the BIOS?

With out knowing the make and model of the motherboard we can not say it that is the correct RAM or not.

I did put in the old ram, and the BIOS was the same, I am not sure exactly what the model of the motherboard is, but i found this:

Then lets run a speccy report to get the information

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s.


Include the make and model of the Power Supply Unit if this is a Desktop.

To publish a Speccy profile to the Web:

In Speccy, click File, and then click Publish Snapshot.

In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

If I am reading correctly manual states

To ensure data integrity, use only Acer-approved DDR4 2400 MHz or DDR4 2666 MHZ type memory modules.

You are running
I just bought 4 x 8 gb 3200 MHz Corsair DDR4 DRAM
Which is the incorrect RAM

Another issue is you are running both Norton antivirus and Windows Defender

@Bruce will have more.

Thanks for the picture

Your current PSU is under powered for the graphics card you have.


The Display card that you have requires a 550 WATT and that one can only put out 432 WATTS and rated to 500 WATTS which it will never put out.

It is and being an OEM system the BIOS is locked and XMP not an option, not unusual to find, Dell, HP and others do the exact same thing and it sucks, they advertise their crap as gaming PCs which sells the end user well short :mad:

Thank you for all your help, but do you think if I buy the same original ram I am using now, to go from 16-32gb will the speed be correct or do I have to change the speed in the BIOS? (which ofc can't do)
