" rel="nofollow - Hello All,

I'm having trouble getting my Corsair Vengeance LPX 3000mhz memory to run at 3000mhz with CAS 15.

System Specs:

ASRock B450m pro4

AMD Ryzen 5 2600

Corsair Vengeance LPX 2x8gb 3000mhz

Gigabyte Geforce 970 GTX G1

EVGA Supernova 650 G3

I've enabled the XMP profile via the BIOS and changed the CAS to 15, but CPUz reports as CAS 16. I changed Gear Down Mode to Disabled and the system won't boot.

Is this memory not compatible with the pro4? Or Ryzen for that matter?

Thanks
