A320 officially supports 2133 - 3200 DDR4 ram, some may or may not support 3000, it might end up as 2933 instead, depends entirely on the mobo. So getting 2933/3000 out of that 2133 isn't an issue for the board it's entirely an issue with the ram. It may or may not OC that high and be stable, it might only get to 2600. Only way to find out is to try it, but I'd definitely go for looser timings, like 16-18-18-38 1T at 3000 and do overnight memtest64 checks.
