[SOLVED] Kingston HyperX 3200 on 2666 motherboard

[burim.baftijari]

I have Kingston HyperX 3200MHz memory (HX432C16FB4/16) . I want to use on Gigabyte B360M-DS3H motherboard that is 2666MHz. But the Kingston say that this memory can operate at 2400 MHz (JEDEC) and XMP at 3000MHz and 3200MHz. How can I set to operate at 2666 MHz?

By XMP.
The board limits it to 2666mhz.
The ram is capable of working on 3200mhz on motherboards that support 3200mhz speed.
The gigabyte one doesnt.
So the ram will work on 2400mhz as it will on any motherboard,and by turning on XMP you will only be able to set it to 2666mhz,since the board supports up to that speed.

Since you don't have an XMP setting for 2666 exposed in the bios, you can download HWInfo and get the hidden certified profile timing table or XMP timings table and then manually set 2666 and primary timings in the bios M.I.T menu. You will have to enable advanced timings mode or whatever it's called in the M.I.T menu, before you can change the memory timings.

Hello,
When I choose XMP Profile 1, automatically the memory multiplier jumps from the default 24.00 to 26.66, therefore the memory frequency to 2666 MHz even if Kingston don't mention 2666 MHz !!! Do I need to test the memory with overloading, even if this is downclock and not overclock?

When they meant that it goes to 3200mhz,they meant every speed between 2400mhz to 3200mhz will work.
That ussually includes 2400mhz>2666mhz>2933mhz>3000mhz>3200mhz.
So your ram speed is limited by the motherboard,but thats fine,since with intel you dont even get that big of a benefit,unlike ryzen who really uses fast ram.

Dear Djoza,

The question was why Kingston say this:

FACTORY TIMING PARAMETERS
• Default (JEDEC): DDR4-2400 CL17-17-17 @1.2V
• XMP Profile #1: DDR4-3200 CL16-20-20 @1.35V
• XMP Profile #2: DDR4-3000 CL16-19-19 @1.35V

https://www.kingston.com/dataSheets/HX432C16FB4_16.pdf

And their support say that better is to buy 2666 MHz memory for this MB, than 3200 MHz.

But the motherboard use at 2666 MHz.

Default (JEDEC): DDR4-2400 CL17-17-17 @1.2V means it will run at that speed and at that CAS latency,without you touching anything.
By turning on the XMP profile,you will get either XMP Profile #1: DDR4-3200 CL16-20-20 @1.35V or XMP Profile #2: DDR4-3000 CL16-19-19 @1.35V and i THINK that is depended on the motherboard.
They probably said that its better to buy 2666mhz since its probably cheaper,and if you went with 3200mhz,it will be more expensive without having the ability to run at advertised speed,which is 3200mhz on this motherboard.
