reduce temps undervolting the cpu

hi i made my own undervolt for my i7 4710HQ and i want to share it. MY PROFILE ONLY WORK WITH THE I7 4710HQ !!!!!!!!

What is Undervolting?
Undervolting is a process which reduces the excess "voltage" given to the CPU using a software. This is widely used as a cooling solution and in my opinion more effective than any other cooling solution available (thermal paste, cooling pad, etc) at NO cost. Results can vary from 5c up to 30c drop in temperature, most will achieve an average of 10c.

Undervolting will NOT compromise performance at all. Underclocking and Overclocking (clock speeds) is whats responsible in regards to performance. Benchmarks will also prove that performance remains the same. Most beginners usually think and assume undervolting will sacrifice performance but they are wrong.

*Advantages of Undervolting
- Cooler CPU (5 to 20°C cooler)
- More battery life (15-30mins more)
- Less Fan noise & activity
- Longer overall notebook life
- Eco-Friendly

first you have to download intel XTU from here:
https://downloadcenter.intel.com/download/24075/Intel-Extreme-Tuning-Utility-Intel-XTU-

and here is the link of my profile ... you just need to apply after you installed intel xtu

if you want to know something, just ask me and i will help you as soon as i can

 

wow ill check this later.. im still at work.. thx in advance..

 

hi.. i have downloaded your xtu undervolt. shall i just open it and apply same xtu profile.. also can i save my current xtu profile before using yours so ill have a backup..

 

Might be nice if you credited the original author

Also, people don't provide pre-set profiles for a reason... same settings may be unstable or have room for further undervolting, depending on individual CPUs (even for the same model, much less different ones).

 

i only take the definition of the word ... i made the undervolt and is really stable because the max undervolt is
CPU CORE = -91.7968750mv
CPU CACHE = -90.8203125mv

and i put:
CPU CORE = -75mv
CPU CACHE = -75mv

more than safe

 

ohhh my god.. i tried your profile ang my computer won't turn on anymore.. my laptop will just light up like the alienware logo and then turn off again like a loop.. waaaaaaaaa.. help pls.. i beg you..

 

someone help pls.. huhuhu

 

for me (4980HQ) such a cache undervolt is a guaranty to crash during web browsing
So yes, any CPU will react differently and safe undervolt for you can result in a BSOD elswhere.

 

In case of crash, the original voltages are automatically restored.

 

meaning? the motherboard is dead? i got a brick laptop?

 

Meaning that if you undervolt too much and get a crash,then normally the system restart with default voltage

Afterward i don't know which parameters were changed in this profile

Do you have the same cpu as the judal57?

 

yes same cpu.. so my case of undervolting is not common? like if there was a problem most laptop will still boot up?

 

Yes, most laptops will still boot up. Such situations are more typical of undervolts done via BIOs or involving an overclock.

Anyway, that's why the general consensus is to experiment by yourself, to avoid any possible problems: -50mV is a much better baseline (-30mV if you are conservative).

 

do you think my laptop can still be saved? reseating cmos battery and ram will the bios reset? do you think its because the undervolt was too much and thats why my laptop cannot boot up? and hopefully my laptop will boot up? my plan is to contact dell.. my laptop is still in warranty. by the way prior to the all of this dell tech agent came to my house to change heatsink without safety equipments like no anti static mat and anti static wrist band. could this be the cause?

 

0lok, undervolt didn't cause the problem. It was coincedental. At worst undervolt causes a reboot, and then XTU won't apply the profile at next boot because of the crash.

XTU doesn't set anything in the BIOS. You can try a power / CMOS reset, but likely it is related to your last RMA fix, it wasn't enough.

Get another RMA to fix it, I wouldn't mention the undervolt, as it wasn't the root cause.

When you get it fixed, start with an undervolt of -10mv.

My worst undervolting CPU was stable at -15mv at CPU defaults. As you OC higher in speed, the stable undervolt decreases.

My current 5950HQ undervolts at -105mV at 35x on all cores, at stock defaults -85mV, at 40x -15mV, at 41x +50mv 36x cache, at 42x +100mv 36x cache.

As you add positive voltage, power/temp goes up - hitting the point of diminishing returns, so for my 5950HQ, 41x is the sweet spot for benchmarks, and 36x for long duration CPU tasks.

Good luck

 

so i have the worst luck then.. huhu..

 

jesus christ !!!!! did you read the I7 4710HQ on the TOP of my post ?????? you cant use my profile on a different CPU !!!!!

 

open the first back panel, only 2 screws and disconnect the battery cable, open your notebook and press the power button for 30 seconds, put the battery cable in place, put the panel again and finish.

 

I am currently running -75mV Dynamic CPU offset, -15mV cache, -10mV graphics, 40 x 4 multiplier, 40 cache multiplier, 101.05 BCLK frequency on my 4980HQ. Hope it is stable.

Ran these settings with the XTU HWBOT benchmark and 3Dmark11, passed both.

 

tried that already.. and failed.. i won't go further on disassembling because it might void my warranty. ill ask dell to fix it for me.. so sad.. T_T.. this is the result of me being greedy to lower temp more.. T_T

 

That's not the proper procedure. The proper procedure is to open the panel, unplug the battery, and remove the RAM. Plug the battery back in and turn it on, you should be hearing 2 beeps repeatedly. Let the computer continue to beep until it shuts off. BEFORE IT TURNS ITSELF BACK ON, insert a single RAM stick, which will load default settings and the LCD should power up. Turn off the computer, unplug battery, reseat both RAM (or single if you have only , just leave it, no need to reseat), and plug battery back in, screw in the bottom plate. You are done.

 

the part you said BEFORE IT TURNS ITSELF BACK ON and insert ram stick.. should i do it extremely fast? and make sure i am able to put it back on before the computer restarts?

edit:
also when the part you said lcd will turn on does it mean it will boot up and i can shut it down properly or i have just to shut it down by pressing down power button for a few seconds?

 

Yes, it should be done quickly before your AlienFX lights come on. Put the RAM in before it restarts. The LCD will light up, meaning you have a fully functional system. The LCD would not light up if your system did not pass POST.

 

i love you man.. i can kiss you right now.. weeeeeeeeee.. thank god.. by the way about judals profile from xtu would it be gone now? my default xtu settings is back right?

 

So it worked, correct? The XTU settings should be wiped/restored to default.

 

when i open xtu program my computer crashed.. i wentbto safe mode and try running my saved default xtu settings and it said program cant run on safe mode..

 

So do the safe thing, and uninstall XTU in safe mode, then re-install under normal windows.

 

i have now open xtu and it said due to instability thingy its said it didnt run properly and now it is loading default settings.. alleluia.. no more tweaking and more playing from now on.. need to contact dell and stop them from coming.. thanks alot i own you one.. thank you.. @judal57 thanks for the lesson.. i know you were just trying to help.. lesson learned.. time to play..

 

Glad I could help. Enjoy!

 

i dont know why you had issues ... I tried with a lot of values to make it stable really bad to hear that... maybe your cpu does not accept undervolt, or you are using a different BIOS, i have the A06, it resolve a lot of issues.

 

we have the same cpu and bios.. i dont know about gpu though.. i have gtx 970m.. i know you were trying to help.. its ok as long as my laptop is fine now.. thanks again..

 

Of course I didn't apply your profile since the idea of sharing XTU profile is senseless
Just telling that what work for you might not work for others
