Is it possible to Undervolt Arrandale?

[deputc26]

I know RMClock won't work

I'm quite sure CPUGenie will not work

So I'm left with either flashing a new bios or some option I'm unaware of.

Has anyone tried this or does anyone have an arrandale laptop?

One assumes you're UV to save power, you don't say. I tried UV my Clarkdale, (same chip, different binning and microcoding) and the UV did nothing to lower power.

Keep in mind all the Core CPU's have over a million transistors devoted to power management. Basically all Core CPU's UV and UC dynamically, so classic UV is no longer meaningful.

This is not true as demonstrated by the ability to overclock at stock voltages. If you can overclock, you can undervolt. Also against this is the static TDP of arrandale family chips as the clockspeed goes down. There is not enough variation in intel's 32nm process for this to work out so well.

Make no mistake, standard arrandales will be some of the most undervoltable CPUs we've seen. There is absolutely no way it needs ~1.06v(<- guess) to push 2.13ghz. I bet it could run that clockspeed at .915v. If they had voltage set as low as it could go all the low end arrandales would use less power than the high end ones giving them an advantage.

sorry to revive this, but came here throu google search and was wondering if either you or anyone found an answer the the OP question. I also believe my 370m could probably push 2.4ghz well under 1v. Hell, even my wolfdale-2m can do 2.5ghz at 0.85
