G1S and rmclock

Is there any benefit of running a computer at a lower FID multiplier but same voltage? Because my g1s is usual running at 8x and .9 volts (which is the lowest i can go) but i also have options for 6x, 7x, and another 8x. should i just disable those? Also i have a g1s-x1, so mine only goes up to 10x. Basically i have 10x at 1.025 and 8x at .9 and a BUNCH of options for 9x. what should i pick for it.

Also it says it has a 1.250 volts and 6x or 8x for short times even though i have 6x disabled and none of them use 1.250 volts.

 

I don't use RMClock, but from using NHC I'm going to guess that you haven't really "disabled" 6x, you just excluded it from RMC's control since you didn't give it a voltage assignment -- so when the cpu hits 6x it accesses it using Intel's default chip voltage for that multiplier (which is probably 1.250), and then when it advances up to 8x RMC takes control again and uses the lower voltage you have assigned.

So, two suggestions:
1. Assign a voltage to all of your multipliers, including 6x. This should force the cpu to use the appropriate values that you want.
2. Pick a voltage for 9x that is between your choices for 8x and 10x - this will keep your cpu from bouncing all over the place and your power curve consistent. Or, try it also at 0.9; some C2D chips are apparently capable of running nearly the entire multiplier set at near-minimum voltage, but ymmv and you'll have to try it out yourself.

 

I'm not sure I understand the question properly...

Do you mean that your CPU runs fine at 8x with the lowest voltage available, and asking whether there is any benefit of running 6x with the same voltage? I'm not sure, but I think the power draw of the CPU increases with frequency even at the same voltage, so yes, there would be a benefit in power draw, heat output. You can test it by using stress tests on the two multipliers and checking temps.

In general: I suggest using on Performance on Demand three multipliers: lowest, largest, and one in between. Once you set a voltage for the lowest and largest multiplier, RMClock will interpolate to give voltages for the clocks in-between. If you know that it can actually take lower values than the interpolates, then you can override.

The voltages should be chosen on the basis of stability checks. There are good undervolting guides out there.
