Overclocking RAM fails

I recently have gotten a motherboard (Prime B350-PLUS) with a CPU (AMD Ryzen 5 1600) and some RAM (2x4GB 3000MHz, Corsair Vengeance). The RAM is on the QVL of the motherboard.

On default my motherboard sets the RAM frequency to 2133MHz and the voltage to 1.2V. If I try to change the frequency to 2933MHz and the voltage to 1.35V, it boots a few times with 3 short beeps, then once with 1 short beep, then again once with 1 short beep to say "Overclocking has failed.".

What am I doing wrong? Is the voltage too low?

BTW: When I try to use the preset RAM overclocking profile, it just boots once, without any beeps. The fans turn on but everything else remains unpowered and dark. On a restart the same thing happens. I waited for 2 minutes but nothing happened. I had to remove the CMOS and put it in again to fix it. Then everything again runs fine, but only on the default 2133MHz - 1.2V. I've got the latest BIOS update and my RAM sticks are in the recommended slots (A2 & B2 or 2 & 4).

How could I achieve my desired speed? What could be wrong?
 
Nothing above 2666mhz divider is guaranteed rock stable over several reboots on any board right now.

The simple answer is you can't reach that speed currently consistently. Wait for bios and memory table revisions to come for better memory performance.
 
Same here with my Team group Dark Pro 16GB (2x8GB) DDR4 PC4-25600C16 3200MHz , boots a few times with some short beeps , installed on
GA-AB350-Gaming 3 AMD B350 (Socket AM4) DDR4 ATX Motherboard , 2666mhz max it will boot ok , But got my 1700 to 3.90ghz stable :)

Exactly, overclocking my CPU is no problem either. I got my 1600 to 3.8GHz and +0.025V Offset.
 
Currently no board is working 100% consistently at high memory speeds anything above 2666mhz.

ASUS CH6 and ASrock Taichi are the current best but they have problems also over say 20 reboots the mem fails to train at high speed intermittently with 3200mhz divider and 2933 divider.

AMD have new code they are testing now which enables high memory speeds, I had a meeting with them to discuss this yesterday.

I am actually developing an 8Pack memory sku that will be 3200mhz + 16gb 2x8 and work with Ryzen. I get samples next week to try our spec on all the higher end boards.
 
Even the "G.SKILL Flare X Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 F4-3200C14D-16GFX " Not running at full speed for a lot of USA/CA reviews on New Egg ,
This over here in the UK in places cost over £175

You can wait for the new AGESA Bios update for your motherboard, which should be available fairly soon. That will hopefully enable a higher RAM speed.

In the meantime, you might achieve higher RAM speed by setting SOC voltage to 1.1v (avoid going any higher). I`ve read that you can try setting RAM voltage higher (max 1.5v, but I'd go no higher than 1.45v).
 
SOLUTION:

I had the BIOS version 0609 and it didn't work.
A few days ago a new BIOS version was released (0803 BETA) for my motherboard.
I updated, put my RAM to 2933MHz, 1.3 volts and 15-17-17(-17)-35 timings and it worked perfectly!
