Windows 7 and undervolting issues with RightMark on laptops

If you've just installed Windows 7 on your laptop, and are trying to use your old RightMark undervolting settings, but find that either the voltages look completely different (esp. the minimum voltage), or that your previous settings cause a BSOD, then the software has probably autodetected your CPU as desktop rather than mobile. Mine thought it was a Wolfdale rather than a Penryn.

This was pretty irritating at first, since I thought I'd have to go through the painstaking undervolting process all over again. Fortunately, I brought it up with a colleague at work, who mentioned that they'd had the same problem and had noticed the setting was different.

Open up RightMark, go to Advanced CPU settings on the left-hand menu, then change CPU type selection down the bottom to Mobile. You should be able to set your voltages correctly now!

Update: for those who are interested in undervolting, check out this excellent guide, and for Windows 7 x64 users you will need to replace the RTCore64.sys in the RMClock install with this one, not the one linked in the article, which doesn't work. (At least, my experience was that it doesn't work.)
