Default Slightly confused with undervolting

I'm undervolting my laptop and the minute with RM Clock Utility. It has a Intel Core Duo LV L2900 CPU (2.0ghz). Firstly, this CPU doesn't seem to exist in Intel's world, so I can't find any info on it anywhere.

Secondly, opening RM utility shows that all multipliers are set to the VID of 1.2375v. However, I can see in coretemp, when it backs down to 6x multiplier, it goes to a 0.95v voltage, however this is not shown in RM Clock. So, I manually set it to 0.95v in RM.

I see there are lots of multipliers between 6x-15x, all selected. But as far as I know, my CPU only uses 15x at full whack and 6x when held back. So is it safe to disable all the other multipliers?

I wouldn't advise it, if its anything like my lappy then it steps the multiplier up gradually depending on the workload, rather than just min and max.

I have looked at mine and all it uses is 6x and 15x, nothing in between.

Anyway, 6x is set to 0.95v and 15x I have down from 1.2375v to 1.20v passing LinX
