Does that change things?
From my, very limited, understanding of a64's, timings are more important than bandwidth at stock. Once the chip is overclocked it is able to take more advantage of the extra bandwidth. So the hz would be better at 260x10 or would I be better running a divider and lower timings? e.g 260 at 166 divider to give 216 hopefully close to 2,3,2,5
I take it the zx will do more than 200 with slightly slacked timings so for 2.6 I would be looking at 236x11. Would this be roughly the same as the hz at 260x10.
