Undervolting what?! With a tx1219.

Hey Guys, It's nice to be here.

I just bought a HP tx1219 and I'm loving it. The only thing that's worrying me is the heat.

I've looked through this forum and been googling nearly every combination possible.

The one answer that seems to pop up is this undervolting with rmclock, but all of the guides available are too complex for me or talk about an old version of rmclock.

Would someone be nice enough to guide me through the process or suggest a similar / easier solution?

Thanks!
Ben.

 

alrite...to have good results,you NEED to have more effort.
read the instructions,it is not commplicated as long as you think that it is very important..
gee...ppl always wants good results with small effort..dont know why

 

Wow Thanks, I said I've read the instructions and it's pretty difficult when they're based on rmclock 1.6 and I'm using 2.3.

Anyway I'll go back with my "new mindset" after reading your post and see how I do.

 

Briefly for RMClock 2.3:

1 Install and start RMClock. Then save any critical work.

2. Use CPU-Z to check that RMClock is reading the CPU voltage range correctly. If necessary, on the advanced CPU settings page select Mobile CPU then apply RMClock will restart).

3. On the main profiles page put the voltage for Index 0 (first on list) as the lowest voltage (if not there already). Then put the voltage for the last index to be a bit lower than the maximum. Select the power profile as performance on demand (in my experience this causes least risk of conflict with other software / OS managing the CPU speed - RMClock manages the voltage for that speed).

4. Then expand the profiles page to select the performance on demand page. Select Use P-states and select all the indices. Then press apply.

5. You can use the monitoring page to see the CPU speed, voltage and temperature.

You need to do some serious stress testing to find the safe minimum voltage for your CPU. The traditional method is to use the Prime95 torture test (run two separate copies for a dual core CPU) while progressively reducing the voltage for the highest CPU index. Go down one step per minute until either Prime95 gives an error or the computer BSODs. Then move the voltage up 2 or 3 steps and do an overnight torture test to confirm the stability.

Most recent CPUs have the lower voltage locked at a safe value.

Only when you have completed the testing and are confident about the voltages should you save the settings so that they are applied at startup.

Good luck. It isn't so difficult.
