Is it OK to use Cool'n'Quiet in games?

Question

Is it OK to use the automatic processor voltage/clock control while playing games?
Will I have pauses or hiccups when the clock changes?
Another question: is there any way to PREVENT the automatic clock control from going all the way to the max multiplier? That's because I'm running 230x10, and I do not want to reach 230x11.
Thanks.

Syar2003,
Great job!! This tools really looks like a superior replacement for AMD's cnq driver (even though it's not a device driver...how odd).
It seems to work like this: you set min and max multipliers (min is usually 5 for a newcastle, but you can change it to 4 like the claws to save a bit more power while just web browsing.  Like syar2003 said, max is respected: if you set 10x max on a newcastle 3200+, it won't jack it up to 11x against your wishes, the way "standard" cool and quiet does.) So in other words, it seems to work as advertised.  Another interesting thing is that it seems to use every multiplier (except half multipliers) between the min and max that you specify. For example if you specify a min of 4 and a max of 11, you'll also see 5, 6, 7, 8, 9, and 10, unlike standard cool and quiet (which gives me just 5, 9, 10, and 11). Not necessary perhaps, but a nice feature anyway.
The tool does not give you full control over voltages. When you pick the min and max multipliers, you also pick min and max voltages, but the voltages for the in-between multipliers are chosen algorithmically by the tool, like it or not. Fortunately, it seems to do a reasonable job at picking voltages for those intermediate steps.  Here are some examples from a quick first run:
Setting multiplier range from 4 to 11, voltage from 1.1 to 1.5:
4x: 1.1V
5x: 1.15V
6x: 1.225V
7x: 1.275V
8x: 1.325V
9x: 1.375V
10x: 1.450V
11x: 1.5V
So it seems to have chosen more or less reasonable voltages for 5 thru 10...still it might be nice if you could override.
Setting multiplier range from 5 to 10, voltage from 1.1 to 1.5, we see some (expected) differences among the intermediate multipliers:
5x: 1.1V
6x: 1.175V
7x: 1.25V
8x: 1.35V
9x: 1.425V
10x: 1.5V
This could be a setting to try with, for example, an HTT of 220, because if you add 10% to all of the speeds, you end up with speed & voltage combinations not too far apart from the previous case, which we know is safe. Will try that later...
To try (haven't gotten to it yet):
-- In MSI BIOS 1.55+, you specify cpu voltage with a number (like 1.5V) and with a fudge factor percent (0%, 3.3%, 5%, 8.3%, 10%). Clearly when using RM1.2, the first number is ignored and replaced with your RM1.2 settings, as it should be. (Haven't tried it, but it would make sense.) But we would like the fudge factor percent to be respected by the RM1.2 tool. Is it, or does the fudge percentage get silently ignored when using RM1.2? Haven't tried yet. If it doesn't work, then there won't be a way to apply good voltages.
