cree cr4 buzzing with maestro dimmer??

I have installed 8 Cree CR4 LED pot lights in the kitchen with Lutron Maestro MACL-153M master and one companion switch. I can hear a noticeable buzz at 50% dimmed and a slight buzz at 100% full on.
Anyone have to same issue???

I checked the dimmer MACL-153M is on the CREE CR4 recommanded list, and CR4 are rated for dimmers.

If I cannot resolve the buzz, I rather have them all off the dimmers than walking into a buzzing kitchen.
Thanks in advance

Did you try lutron's tech support? They're pretty helpful.

I have 12 Cree CR4 lights on that same dimmer, with a companion switch, with no buzzing.

For my LED UCLs, I found that dimmer didn't work and had to switch to the ELV dimmer (MAELV-600) to stop buzzing. I think the overall brightness with this dimmer is very slightly lower at 100% (compared ti no dimmer), but there is no buzz.
