I'm not really sure how to use RMClock. Is there a guide on how to use it to undervolt the IFL90?

I have a E2180 with a Gigabyte mobo that allows for undervolting. At 2.0GHz, it can still run dual-prime95 stable at 1v (with SpeedStep enabled and confirmed working, and voltage stuck at 1v so it won't go higher when the multiplier goes higher).

I'm thinking the T7500 in the IFL90 should be able to hit the 2.2GHz at a lower voltage as well, allowing for cooler and longer lasting battery life. If the BIOS doesn't allow us to change voltage, how does one go about it with RMClock?

U must unlock VIDs in Rmclock to be able to go down below 0.9v

If you can set lower voltages in RMClock it doesn't mean that the CPU will actually take those settings, BIOS and CPU locks will limit how far you can go (up or down).
I am not using RMClock right now because it won't manage the "special" low voltage @800Mhz of 0.85v when idle...undervolting won't help much in battery life by now.
Santa Rosa platform still needs some time to be well supported I guess.
