On my Abit mobo GTLRF was clearly marked and adjustable by percent, so I'm puzzled.
Gigabyte have set GTL ref to 63,5% (0,760v), both for CPU and MCH (NB) in the bios.

CPU Termination x 63,5% = CPU reference -> 1,20v x 63,5% = 0,760v

CPU Termination x 63,5% = MCH reference -> 1,20v x 63,5% = 0,760v

(With a dual I found that MCH ref ~60% worked better then 63,5%)

One way is to set the CPU/MCH ref value when CPU Term is at 1,20, it change/scale with the CPU Term, so no need to change CPU/MCH Ref value even if you change CPU Term.

Hope this help you some.
