Vengeance RGB Pro 3000 works maximum at 2666
 
Ryzen 2600
Asrock B450M Steel Legend Bios 2.0

Won't boot with XMP 3000 loaded. Also on everything above 2666. Voltage 1.35, timings 16. May boot up on 2733 with like 18s timings. Slots 1-3.
While in slots 2-4 won't boot even at 1866 but 2133 lol. TF? Bad CPU? Mobo? RAM? The lights are beautiful tho.

Try using AUTO, set DRAM voltage manually to 1.35, adjust frequency to DDR4-2933. (using primary slots A2 & B2)

I have exactly the same set up with the same bios 2.0 and mine booted with vengeance pro 3200 in slots A2 and B2 i got everything set up on my pc first once completed i then enabled XMP and everything worked as should no alterations to any other settings .

It can't start with any values other than auto in these slots. Even lower than 2133 somehow lol.

Yeah thats exactly what I was hoping to get when bought these ones :D:
Btw, do 3200 and 3000 share same chips but 3200 has cl16 xmp profile and 3000 cl15 one? So 3200 is just overclocked 3000?

Well, it's all works now. What I did is switching the modules in their places. Now it runs xmp 3000 but still 16 latency not 15. Pretty strange tho do you guys have a clue?

CorsaOpel,

You should specifically indicate what model and version ram kit you have.

I must have misunderstood your original description. So you are using AUTO correct?

Now check your timings in the BIOS/UEFI. You may override the AUTO settings by entering your primary timings manually according to your JEDEC or XMP memory module timings. If you decide to use your frequency and timings from your XMP profile when set to AUTO also set the specified DRAM voltage your XMP profile wanted to use as well.

Note if your steel legend bios is similar to the other ASRock Ryzen boards then it may have two options for memory. One for XMP profile and the other ASRock profile. It is designed that either one or the other is set for XMP but not both. If either of those options individually don't work people tend to set these to AUTO then set frequency, timings, and voltage manually.

So you think that it's unbootable (it's still is without tweaking) with xmp because it can't hook up all the settings from the profile? Also it won't let you change timings when set to auto. I found out many am4 boards can't run odd timings so now using cl16 3200 manual settings given by calculator. So I believe this one is pretty solved :D:

No I was just trying to point out ASRocks BIOS/UEFI is weird and it may let you set both profile options when it probably should enforce setting one or the other not both. Otherwise it's confusing and problematic.

It should still let you change timings regardless if your set to AUTO, XMP profile, or ASRock profile. (at least it did on my B450 and X470 at the time) Enter DRAM configuration and you should be able to see what it decided to use and you may override any particular timing manually.

I've never read of issues specifically between running odd or even timings.
I've run 15-17-17-39-55-1T no problem with my kit.

Anyway since your problem is solved great.

Turn OFF Gear Down Mode in the BIOS under the memory timings section. It may be way down near the bottom of all timing settings. This will allow for odd numbered latency instead of being rounded up to the next even number whether running XMP (DOCP) settings or manually overclocking your RAM.
