RMClock really isnt working quite perfect on Windows 7 u can see spike of stock clocks even with undervolted clocks.. =.= although one of the NBR did mentioned it does happens as Windows 7 is newer than RMClock latest release.. and he mentioned shud be no problem lol..

I got even bigger problem lol, RMClock refuse to run, it says:

"Cannot install or Loas RTCore64 driver."

The thing is, I think my Windows blocked the driver because there is a message say's it is not a signed driver or something... Any solution?

download, extract to rmclock folder and overwrite the old driver.

M1X i suggest u test the undervolt on your OC'ed clocks .. I mean for more stability in case when u need to OC the processor.. biggrin.gif

For stress test, they suggest doing 2-3hour at the most as it might put a strain on your CPU/FAN. =)

User ID: M1X
Laptop Model: Asus UL80VT
Processor Model: Intel SU7300 @ 1.733GHz, 1066MHz, 3Mb L2, 45nm, 1.037V,
Stable Undervolted Voltage: FID: 6.0, VID: 0.9

(where to check CPU wattage?)

CPU Temperature: Before: 63,62, After: 56,55 (not much, but still OK, consider this already an ULV laptop... tongue.gif )
3DMark06 Score: Before: 3463, After 3440 (no affect at all biggrin.gif )

But RMClock didn't give any lower options anymore than 0.9V... No other options for FID as well.

------------------------------------------------------------------------------------------------------------------------------------------

OK, I make another checking around and find these (on Turbo Mode):

- Quite Office Mode, Power4Gear lock CPU voltage on 0.875V, so DON"T tweak with RMCLock anymore, which will cause you eat more energy instead...
- Multimedia/Max Performance Mode, 0.875V on idle, peak to 1.03V whenever running anything.

Also, RMClock seems to having some clashing with Power4Gear, for example swithcing on/off RMClock might result in Power4Gear switching mode as well~ doh.gif And just now my laptop hang when switching from Quiet Office to Performance DURING RMClock is running.

So, it is wise to check voltage on different modes, and then decide which mode can do undervoltage.

Your processor is ULV so i dont see a point in undervolting it when its already ULV lol..

Yeah that's right~ But it is slightly useful when on the max performance mode though sweat.gif

But totally useless when on Quiet Office mode (when I using battery) sweat.gif

Just if I can tweak it down to 0.8V... whistling.gif

LoL.. then better dont undervolt.. Since normally overclocked u may need a little voltage boost lol..

Havn't check what the voltage without Turbo33~ XD
Will do it tommorow, not now... XD

actually there's registry hack to let rmclock choose below 0.9v
but seems like from feedback, it doesn't work, or still treat as 0,9v.....

Voltage can be seen from CPU Info in the RMClock app..

Better u use CPU-Z smile.gif U can see multiplier, clock and voltage changes.. biggrin.gif

my laptop has the same case as M1X, as its FID only has 1 which is the 6.0x. laugh.gif
