Its possible, if maybe unlikely.
BTW OC ram on an Intel mobo yields very little by way of performance increase. If it were Ryzen i'd say yes, try an OC, but for Intel , it hardly makes any difference, except in benchmarks.
The main point here is: No-one can tell you what voltage to use or settings to dial in. You need to trial and error and figure out what works best for YOUR dimms. All kits are different. What works for one set, might very well not work for another. TBH though going from 3000 to 3666 is too big a leap. Maybe 266mhz increase, but 666 is a bit of s stretch. Otherwise everyone would just by those 3000 dimms and OC them to 3666. The manufacturer would be shooting themselves in the foot. At 3000+ the mem will have a voltage (normally) of 1.35v To get it to go to 3666 you will have to give more voltage. This may harm your DIMMS.
Research your ram modules/mobo and you will find out how to OC the ram.
