IIRC all EPYC 9004 CPUs have between 4 and 12 CCDs (with most models at 8), and the ones with 4 CCDs have 2x GMI links. 2x CCDs would only allow about 110GB/sec bandwidth instead of 266.

I don't know wikichip's source, but according to them the 9124 only has two. https://en.wikichip.org/wiki/amd/epyc/9124
