Ryzen 7 3700X: cpuid function ID 0x80000006 returns wrong number for L3 cache associativity

Requesting cpuid function ID 0x80000006 on a Ryzen 7 3700X returns 0x01009140.

So the value for the L3 cache associativity (bits 12-15) is 0x9

According to the spec(PDF page 75) this value is reserved.

Any idea were the issue lies here?

Is the spec wrong or the CPU bugged?

 

Edit: We now have a Ryzen 5 3600 which shows also returns 0x9 bits 12-15.
