DDR4 Corsair RGB CMR16GX4M2C3000C15W compatibility

Hi,

The XMP setting is 3000Mhz CAS 15^^

For now the CAS 15 dosen't work on my two AM4 motherboard but maybe the new ryzen cpu will help.

Thank's your answers, finally a new bios fixed the problem^^.
Topic can be close (don't know if I have to do it mylself^^)

Great.
I think the 3000MHz is more important than the CAS.
Is the XMP setting CAS 16?
I think Corsair put the XMP in the RAM so maybe ask them.

Hello :)

Originaly, I bought this corsair memory to work with my asus prime x370-pro (in the QVL) and after I tried to have them work on my new computer (asrock MB steel legend).
None XMP or manual settings make them work at 3000Mhz, it seems to be locked in 2133mhz (but I just tried XMP and 3000mhz frequency maybe it could run at other frequencies..)

Anyway, when I will buy a new ryzen 5 3xxx, I will see if there any improvements.

In the meanwhle I bought a new kit, G.Skill Ripjaws 5 (F4-3200C16D-16GVKB) that doesn't figure in the asrock QVL, this time I roll the dice^^ Maybe it will perform better, the price was not expensive (87??for 2x8Go), if not I will keep it from another computer.

I will try to think of updating this topic when I'll have the new ryzen cpu.

QVL in my experience never test a lot of the available RAM (which locally tend to be very limited choices).
I have yet to buy any QVL RAM and I've never had a problem getting stated speeds.
Maybe I've been lucky.

Sometimes they work when overclocked, sometimes they don't.
You could try the other slots.
A new BIOS might fix it.
Are you using an XMP profile to set it to 3000MHz?
You could try increasing the voltage to the RAM but check all the specifications first.

See the Memory section of:
https://www.asrock.com/MB/AMD/B450M%20Steel%20Legend/#Specification
I think the Ryzen3 1200 is Summit Ridge (I hate code names).
The charts don't seem to have overclocking.
2133MHz is the lowest.
I would only think you would get that if you had 32GB.

I would try the other slots and make sure it is using an XMP profile.

You should be able to see the voltage in the BIOS, 1.2 is the default.
If it doesn't see XMP, you'll need to set everything manually.
Increase the speed to 3000MHz and the voltage to 1.35 and 15-17-17-35 but XMP is easier.
