Want to get the most out of my RAM, but enabling DOCP causes my PC to fail to boot. Any suggestions?

Help Request - RAM

CPU: Ryzen 7 2700 (base 3.2GHz, OC'd to 4GHz w/1.35v)

CPU cooler: Corsair Platinum H100i RGB

GPU: EVGA RTX 2070

Memory: 4x8GB Corsair Vengeance RGB Pro 3000MHz

MOBO: ASUS Prime B450M-A

PSU: 600W 80+

Like the title says, simply enabling DOCP in BIOS isn't working; it fails to boot after 3 attempts. I've tried googling but gotten some mixed results, at first it seemed like getting 3000MHz out of all 4 sticks is a no-go but I've seen others say they've gotten 3600 out of 4 sticks. I haven't tried just running 2 sticks yet, but with this config is 3000MHz on all 4 sticks out of the question?

I have heard R7 2700 max supported Ram stick frequency per stick is 2933mhz. I got a r7 2700 too with Asus b450m gaming/br model. Confirm this, i am not sure this is true however.

I just looked it up and you're right, the 2700 supports up to 2933MHz and the B450M-A supports up to 3200MHz. I'll try lowering the clock and see if it works thanks

Which version does it say on the Corsair labels? E.g. Ver 4.32

4 sticks on that setup is hard run, and the max validated speed in the QVL is 2800.

Would the version number be on the RAM itself or somewhere else? The actual model number for this RAM is CMW16GX4M2D3000C16 and I couldn't find it at all on the QVL for my mobo =(

Ver 5.30 is Hynix AFR I believe. Not too friendly with 4-dimm configs.

You'll likely need to reduce frequency if you want to use XMP.

But you can also try DRAM Calculator for Ryzen if you really want the extra speed.
