Question... by undervolting my inspiron 9300 I will not see no decrease in performance in terms of games and graphics?

More appropriately i should ask what are the drawbacks of undervolting?
Thanks

if i do this process should i have my laptop plugged in or on battery power? or doesn't it matter.

Prime95 failed after an hour @ less than 1.116v.

Testing at 1.116v.

The lower the voltage, the less heat you have.
The lower the voltage, the more unstable your computer might become IF NOT TESTED CORRECTLY.
The original post is actually a little misleading in the amount of time you need for testing. A few hours won't cut it. You need a full 12-24 hour heavy duty test to ensure that the voltage will run stably.

In terms of graphics performance, it does nothing (or it shouldn't).

kinrya,

Doesn't matter.

This undervolting sounds really exciting! My concerns though are:
Will it damage the laptop hardware?
Does it decrease overall performance of laptop? (stability, speed, etc. etc.)
Can I switch between undervolting modes and normal modes?

No (as long as you properly test system stability), no, and yes (although there shouldn't be any reason to do so).

needledik, sorry i didn't quite get the 3rd step of your guide.
it says launch, download and begin calculations?
what is it exactly that i have to run on prime95?
also, it's rm clock utility that we're using, now cpu rm beta 5 version right?
i really want to try this out, but i having a litte trouble following the steps
hope i can get some help.

I don't think so. OVERvolting it might.

As long as you flood the FPU with enough calculations as a test for stability, you should be fine.

No idea.

Very nice. I was able to drop my Dell 600m 1.6 Dothan to .988. Under full load for a few hours, CPU temp never got above 55c and the fan is barely moving. Previously at 1.340 it would hit 67c at full load and the fan would be going full blast.

I also did not use the HLT option since it seemed to confuse task manager and the inspiron fan control app.

As a side, this tool also seemed to have better results on my dual Xeon Dell 470. Previously if I activated the speed step on the Noconas by telling windows minimal power management, it would have a hard time speeding up when it should. The RightMark seems to activate those settings correctly. Last night I played City of Heroes for a couple of hours and usually when I'm done the machine's fans are blasting, last night there was just a soft breeze.

It shouldn't be necessary, since Windows will issue the HLT instruction to the processor when the system is idle anyways.

This is a great program! It completely allows the most from the efficiency of the P-M.

I have a 1.8 Dothan in my I9200.
Minimal voltage already was .700 and the max was set to 1.34 V. (I assume the program chnages these maximum/minimum voltages according to the CPU model. That would be the safest way to keep folks from cooking them.)

I now have my max set to 1.068 V. I'm still testing with Prime (and playing NFSU at the same time ). It failed at the step lower.

[(EDIT...) Posted too soon. I've had to go up one more step to 1.084V.)

I run SpeedSwitch XP as well as I8kFanGui. It was really something to watch my temperatures go from 62* C with both fans at high speed (while running the stress test) down to it's current 49* C with both fans on low speed under stress.

I can now confidently reset my fan switching thermal thresholds so that it may be possible that the fans are hardly ever on slow speed, and never at all needing to be on full speed.

This is really great!


I do have concerns about freezing, etcetra, in the future. However, I never once had the screen freeze up even for a second while playing NFSU with Prime running! (Game settings at fullest detail, default Omega settings for Radeon 9700).

I look forward to more testemonials from other Dothan users.

INSPIRON 8600c here.

1.116v MAX
.700v MIN.


Just a question, does everyone set .700v for their MIN? I just went all the way to .700v and never looked back.

I am seeing very nice results. With regular browsing, I've seen a 6* drop. CPU (see below) now hovers around 39*C with an Evercool NP-101

Under Prime95's "torture test", which one should I be using?
I only have 256MB RAM. After reading the help text for Prime95, I realize that it could be the RAM itself causing me to crap out.

I thought last night I was nearly on track with 1.086V as the high, but when I started stressing again this morning, it puked.
I was using the second choice. Now I'm testing on the first choice.

Use the first choice. That stresses the FPU the most (which is what you want to do).Since you're not messing with the RAM voltage, they don't need to be tested.
