The "Undervolting" Guide

[flipfire]

I used RMclock to force my CPU to run at the minimum FID (4x) then stressed with Orthos for more then 1 hour and nothing happened. I did the same for all the other FIDs (5x, 6x, 7x, 8x) one at a time still nothing happens. My computer seems to freeze in about 30mins-3hours as long as i have RMclock running and i'm doing almost nothing. I've used several versions of RMclock and still have the same problem. Do you think ACPI or some advance setting will have something to do with this??
Will be very grateful if someone can help me fix this problem. Flipfire, do you have any idea??

Sorry, I can only guess its a bug in RMclock itself. Ill try to figure it out though..

rtrdogs undervolt was perfectly fine until he sent it for repairs to HP due to the frail LCD cables. After he recieved it back, RMclock was causing issues and got the same symptoms/problems as you which really stumps me. The only variable between now and then was HP touched the motherboard/internals

i used to work in office with the lowest possible settings without dynamic switching. i just switch to dynamic when i need more power while working. so im working with 2 profiles.

No the battery is fine. i just want my system as silent and as cool as possible.

On a T7300 (Asus G1S-X1) I have been running the CPU at these settings just fine for the past two days:

6x - .9000V
7x - .9250V
8x - .9750V
9x - 1.0000V
10x (max) - 1.0250V

The 10x multiplier was at 1.2500V to begin with. It lowered my max CPU temps on both cores from 78 to 69 and my battery life has increased from 2:30 to 2:50 on the Power Saving setting (locked at 6x, .9000V).

Great guide. Thank you.

On my T7300 I have..

6x-.8500v
7x-.8500v
8x-.8500v
9x-.8875v
10x-.9375v
all running stable

The 10x multiplier was originally 1.1750v
Is this right? I mean it seems so low..

Also, how can I get it to idle at 800mhz? The lowest it goes is 1.2ghz unless I set it to no management

[flipfire]

Yeah they do seem low which makes it a very good undervolt. Run it for a few days, if you get no BSOD then id be very very happy if those low voltages are truly stable. If you do get BSOD's then raise the voltages a little higher. Dont be worried about your low voltages. If it passes a 1hr stability test with orthos, then its most likely stable. If your really worried about it then raise them up by .025v

Again, all processors have different voltages tolerances, they are not built equally so dont be suprised if voltages arent the same as others with the same processor

Do you have SuperLFM? If you do, just set it on the 6x multiplier instead of 8x

How much cooler temps did you achieve with undervolting? Please state max temps before and after UV'ing

[darkcond0]

I'll take some pics of the results later when I have time
Yeah, I already have SuperLFM set to 6.0x but it's still 1.20 ghz..

edit got the pics
before.. usually around 73-75


after, hovers at around 66 most of the time


The thing I appreciate the most is the fan noise (lack of ). Before undervolting, the fan would turn on low after 30 seconds and then ramp up to medium in 3 min, and finally to max at around 4.5 min. After undervolting, the fan doesn't go on at all until 4 min, and then ramps up to medium after 7.5 minutes. It never went up to max speed. I wish I could go lower than .8500v..

Thing is, I still can't get it to idle at 800mhz, even with SuperLFM set to 6x. It's stuck at 1.2ghz

[flipfire]

Your using RMclock cpu page and not CPU-z to measure the SuperLFM right?

Have you made sure that Superflm index is ticked in the Performance on demand Sub profile page??

On a T7300 (HP 8510p)...

Before uv'ing i was getting cpu overheat detected warning from RMClock and temps were around 99C...Seem way too high.

So ive followed the steps, set my 10x multiplier which is the highest before IDA one.

default was 1.200. Its been testing for 25 min at .9875 - temps are hovering around 92-94. Lower temps but still crazy hot....

One weird thing i have everest open as well monitoring temps which matches the temps in rmclock, but under voltage values it shows the cpu core @ 1.1v???

[flipfire]

I think there might be something wrong with your fan or your heatsink isnt seated properly. No processor should run that hot.

Im not sure why everest is showing that voltage. Try using CPU-z, its more accurate

I ran the computer all afternoon long with the RAM in place like normal and RMClock off. No BSOD. I'll run it tonight with the RAM in place, RMClock on and see what happens.

Then I'll move to switching out the RAM to see if I can pinpoint this further.

I was just wondering since HP outsources the repair to Quanta if they replaced the entire mobo instead of just the LCD cable. This is all very peculiar!

I wouldn't be surprised if they change the entire motherboard....they switch those things so much with HP laptops having problems...They must think its the cure for all problems which it is not...
