Question XMP not working ?

[Isma.PKNM]

I tried enabling XMP and using 2933 MHz for my RAM but when I save settings and my PC restarts, when I check my RAM, it still in default speed: 2133MHz.
When I check back the BIOS, the XMP is enabled and saved at 2933 MHz but doesn't apply for some reason.

Why doesn't it apply the changes?

RAM: Corsair LPX 32GB DRAM 3000MHz
Motherboard: Gigabyte AB350M-Gaming 3-CF

Is there any compatibilty issue?

how do you read the settings outside the bios?

Maybe is a rookie way to check it but in task manager, performance and memory.

try CPU-Z, at the memory tab should be written ~1467MHz

did you really set XMP in BIOS? Are you eventually using the gigabyte software in windows to edit it?

if you don´t have a AMD 7th Gen A-series/ Athlon™ X4 series APU, update the motherboard´s BIOS to the latest F51h using Q-flash in BIOS, not windows
try XMP afterwards again. Eventually try a different XMP profile if available

if you have a AMD 7th Gen A-series/ Athlon™ X4 series APU, update the the BIOS version F25

Here you have all my info in CPU-Z. In memory tab is written 1064.1MHz.

I have no idea about BIOS so I posted everything in the link before. I've never tried any gigabyte software, I just tried to enable XMP like this.

Why it doesn't apply the changes?

Probably doing something wrong.
Can you show screenshots from CPU-Z - memory and spd sections?

Show BIOS settings, you're using.

Here you have the SPD section screenshot , memory section and here is my BIOS settings.

Update the BIOS to F51h, currently it´s F50a and outdated

why did you set it manually to 29.33?

 

[SkyNetRising]

It looks like you have loaded XMP profile and then changed some settings afterwards.
Disable XMP, then load Profile1 again and save.

I've heard to some people that set to 30 got some crashes and they recommended to put it manually to 29.33

I did this and my PC tried to turn on 3 times and each time it turned off after two seconds. Then it booted normally but with the default MHz without applying the bios changes.

That means automatic ram overclock is failing.
You have to overclock manually.

Set latencies to 15-17-17-35
Set DDR voltage to 1.35V
Set command rate to 1T

Set frequency to 2133mhz. Test. Should work fine.
Then increase frequency and test after each step.
2400,2600,2800,2933,3000.
When test fails, then return to previous settings that worked.

You said 4 numbers in latencies but I can see 5 in my BIOS, 15,15,15,15,36.
1.35V DDR voltage is ok to my specs? Now is set to 1.2

Yes. You have tRCD split into two values - tRCDRD, tRCDWR.
Use the same value in both.
So 15-17-17-17-35

Increase DDR voltage to 1.35V. This is standard DDR4 overclocking voltage.

 

[helpstar]

BIOS updated yet?

 

[lolvatveo]

disable xmp and overclock manual by changing the dram multiplier in advance memory settings tab. base clock is the last option to overclock ram

I did it and the max MHz I could get is 2866MHz , if I use 2933MHz my pc seems to crash and when it turns on ram is set to default value, 2133MHz. It is solved or it should get 2933MHz?

 

[lolvatveo]

try 2 way: leave the ram timing auto or follow jedec/xmp standard in cpuz when overclock

2866MHz is quite close to 3000mhz. I wouldn't sweat about it.
You're reaching 95.5% of rated ram frequency.
