Multipler on A7n8x

Ok, this has probably already been asked and all but here goes.
When i set the multipler for 13+ it sets it to a much lower multipler reducing my clock speed dramatically. Is there anyway to set this to 13+?
Thanks

You will have to mod the CPU to use 12.5x and higher...the Abit Nf-7's are the only board out right now that can read the 5th fib...which gives CPU's using under the 13x multiplier the option to use up to either 15 or 16 without modding the CPU...

you can do the wire trick which is pretty simple to get access to all the multipliers
