XMP profiles not working

[Mando772004]

I just got 2x8 ddr4 hyper x fury 3733 cl19 memory and xmp profiles arent working. it says my first xmp profile is 3733 and my second is also 3733. firstly the second profile should be 3600 cl17 and when i try to boot onto the first profile it boots in with 2400mhz speed not 3733 as mentioned in the bios. whats causing this weird problem

What CPU are you running? Not all Ryzen CPU's can run this 1:1 with fclk...

how do you know that exactly? what does the SPD tab on cpu-z say?

what are you using to  see that exactly? use cpu-z or hwinfo and check.

i use cpu-z and i know because it states that on the page of hyper x

so it says 1200? if so then yes it's running at 2400.

you could try clearing the cmos, set the FCLK to 1866 (though not all zen 2 chips can do that) and try to enable xmp.

op is using this exact RAM

there should've been 2 XMP profiles, but only 1 appeared in the bios

it worked but it doesnt run on cl19 as mentioned in the bios xmp profile

what does it run at?

cl20 and the 2nd xmp profile is the same as the first though it should be 3600 cl17

alright then

i ran it and it booted on 3733 as well but i set the fclk freqency to 1800 thinking that the 2nd xmp profile is 3600 cl17 as mentioned

[Mando772004]

my xmp profiles are bugged

and at what timings? if they're cl19 then it should be fine, why it's not 3600? check the spd profiles on cpu-z and check what xmp-2 is.

can i just set them manually if so can you tell me which timings exactly do i set? it says 17-21-21 on the hyper x page what exactly do i set the 17 and the 2 21's to? like TCL or tcr or what

yea, you could try and set them to the advertised timings. also check the spd tab on the cpu-z.

i sat them manually only 3 of them cuz the last 2 didnt work they were above the maximum so basically i set CAS latency and RAS to CAS and RAS precharge last 2 were numbers above the max and it worked but im on 3600 cl18 not cl17 unfortunately. i feel like there is something in the bios wrong

you could try..setting the soc to 1.1 and dram to 1.35 and then try 3200 with xmp and then try 3600 with those values and then try 3733, also at 3733 set the FCLK to 1866 and check if that works.

i dont get what you mean by try 3200 with xmp? firstly i set soc to 1.1 and 1.35 then what do i do with the frequency and timings?

set the frequency to 3200 while xmp is enabled.

what about fclk? do i put it on auto or half the 3200? and also what about timings
