Dell 14z undervolting

Not a 14z, but I have a 1555 I have underclocked my P9500 to 1.0375 at max and it goes to .925 at lower multipliers

 

I used it on a battery, from full charge to 10% (or was it 7%), doing what I would normally do: watching a movie, chatting, typing, etc. It discharged in 4:30 hrs, which is not bad, I think.

 

I found something that'll stop the fid/vid jumping. The solution posted sometime earlier was set the windows power thing to 100% min/max, but that wasn't working for me. After searching around for awhile, I found out that you need to uncheck "enable os power management integration (restart required)" under management. Fixed mine, and I'm sure I'll get some more bat life off of it.

 

I just followed the undervolting guides and suggestions in the forum, so I thought I'd add my results. I ran orthos for 10minutes with no management, then ran orthos for a bit over an hour after changing to Performance on Demand.

Multipliers 6,7,and 8 are set @ .875 and multiplier 9 is set @ .95. Temp drops were about 11degrees in cpu core.

I followed the undervolting guide but could not get RMclock to run so i ran CPUGenie and was able to undervolt my t6600 processor in the studio 14Z.

I dont know if i am lucky but i am able to run all multipliers 6 to 11 set @ .925V ( the min for t6600 i think).



What do you guys think? is it common for a t6600 to be able to run at this voltages?


The reason i am asking is that my Studio 14z had a screen problem and after sending a technician for in home service i got another display with a blue lit pixel. So dell has offered to send me a new replacement and i am worried the processor might not be able to run at such low voltages?

 

If you have read the undervolting guide, you'll know that you are not going to cause any damage by running at low voltages. The worst that will happen is that your machine will power down.

 

Ya i know that. What i want to say is that i have a good undervolting CPU in my current system and dell wants to replace the system with a new one.

I want to know if it is common to reach .925V for a t6600 and if i should try to keep my current system.

 

Hey, Mastershroom, did I understand that right? Have you got DFFS and/or SuperLFM working on Dell Studio 14z?

I'm annoyed that my 14z, which I hoped would have great battery life, is stuck at a minimum clockspeed of ~1.6 GHz, even at idle.

When I've attempted to use RMclock to enable DFFS, my laptop just crashes. Reading through this thread, I got the impression that because the 14z doesn't use an Intel northbridge, Super LFM is not available.

If you've managed to get down to 800 MHz on a 14z, I would love to know what settings you used!

Thanks,
