Hello,
My ram OC (XMP) doesn't work like it's supposed to do because i have two (XMP) options one is 3000Mhz and one is 3200Mhz
The 3000Mhz options works but only after 2 or 3 restarts and the games keep crashing
The 3200Mhz doesn't work at all (i get some beeps and then they go back to 2400mhz)
Currently im using 2400Mhz so i don't get crashes
Specs:
CPU: AMD Ryzen 5 1600 (AF)
GPU: AMD Radeon (TM) R9 380 (GIGABYTE Technology)
RAM: HyperX Predator DDDR4 16GB 3200Mhz CL16 (2x8GB) 1.35V
Motherboard: ASRock B450M Steel Legend (Bios P2.90) [There are some bios updates on the site but i don't think i need them]
PSU: 750W at +12V is rated for 80V and at 3.3V and 5V is rated for 28A
I checked on the Motherboard site if the actual RAM is compatibile with the CPU at 3200mhz and it looks like it is compatibile at that speed
And here is the original motherboard site: https://www.asrock.com/mb/amd/b450m steel legend/#Support

XMP don't you mean?
tpm is slightly different to ram.

what are the codes for the ram?
https://www.asrock.com/mb/amd/b450m steel legend/#MemorySR

the newest BIOS version you could get is 2.50 as all others after it don't support CPU - you shouldn't be on 2.90 with that CPU - Summit Ridge
Note on 2.90 - ASRock do NOT recommend updating this BIOS if Pinnacle, Raven or Summit Ridge CPU is being used on your system.

So bios update won't help... wonder if its reason

CPU should support 3200 though.

Seems some of the websites I rely on call it Summit Ridge and others Pinnacle ridge. Its the AF variant that is the kicker.

BIOS version is still a problem. You shouldn't be on 2.90

But on the Motherboard site it says at my CPU P2.90 bios version if you look at the cpu support list

The 1600 AN is the original 1st G en Zen (Summit Ridge) . The 1600 AF was a later release based on Zen+ 2nd Gen architecture (Pinnacle Ridge). For all intents and purposes, the 1600 AF is a 2600 with slightly lowered specs.

Neither one has any guarantees on reaching 3200MHz ram speeds, even with Agesa updates, a Lot depends on the ram itself. If using Samsung B-die, it stands a very good chance of being stable, Micron based is a little more iffy, but SkHynix based ram still can have issues.

3000MHz is an oddball. AMD has always preferred a 133Hz x multiplier bus, in preference over Intels which started out on 100Hz bus, way back in the early 80's. As a result, more modern mobo's run 200/266 as the options. Some mobo's don't agree with that much and only run 266 base.

3000MHz is 15 x 200 x BCLK. 3200MHz is 12x 266 x BCLK. Actually easier on the memory controller. 2933MHz is 11 x 266 x BCLK. So you'll find that with AMD, 2933MHz and 3200MHz are best suited.

Set XMP profile. Where it says Dram Speed, manually change that from 3000MHz to 2933MHz. Later down some menus is a place to set FCLOCK. Manually set that for 1466.

Don't let the numbers fool you. There's almost Zero difference between 2933MHz and 3000MHz, you are talking about figures on the nanosecond scale.
