fix overheating laptop / pc with undervolting processor

undervolting is the process of reducing the excessive voltage to the CPU by using the software. Undervolting does not affect performance at all. affecting performance is the overclock and underclock. Undervolting is not equal to underclocking.

Not all the same processor, each processor models have different voltage tolerances. Intel put on a standard voltage stable (and high) to each chip. The problem is the manufacturer of very high standard voltage. Undervolting try to tune to the lowest stable voltage.

Undervolting process takes a long time, because we have to find the lowest stable voltage for each multiplier on the CPU. Multiplier associated with SpeedStep technology, cpu works full power each time, the multiplier is used to dynamically adjust the cpu clock. (sign multiplier: 6x, 7x, 8x, etc).

* For now, Atom processor, ULV and i-core can not be undervolt.

you need:

1. RMClock v2.35 (main program for undervolting).
2. Orthos CPU Loader (using that to stress test the CPU and look for voltage stability).
3. HWMonitor or everest (to see the realtime of CPU temperature).

* for 64 bit OS will have to download special drivers. copy and paste into the installation folder RMClock. another link.


check Max Temperature before undervolt

First we must achieve the max cpu temperature.
1. open HWMonitor, see the temperature for the cpu, if there are 2 cores it will indicate the temperature of each core.
2. Open Orthos, select "Small FFTs-stress cpu".
3. Click Start on Orthos, and run for 10 minutes, check your cpu temperature rises in HWMonitor.
4. after 10 minutes, click Stop to stop the test, record the max cpu temperature.


Installing and Setting RMClock

1. install RMClock
2. run RMClock
3. click the tab on the left of "Advanced CPU Settings", refer to the settings in the screenshot and click "Apply".

* AMD users need to check a "P-State Transistors" for a better undervolt

setting Profile

1. Open Profiles -> Performance on demand as in the screenshot.
check "Use P-State Transitions" and then check all the "Index" checkbox at the bottom, click Apply.

2. Open Profile tab (main profile).
select performance on demand for AC Power and Battery, check all Normal-type multiplier. if your cpu showed SuperLFM and IDA, uncheck. click Apply.

undervolting

1. starting from the largest multiplier (see screenshot above),
at the screenshot looks default voltage is 1.1750V
we have to do is to lower the voltage, and voltage stability test page, do it gradually.
0.025V lower voltage per phase until it finds an unstable (in the stability tests below)

2. to reduce the voltage of each, click Apply. if not, the new setting will not affect.

3. To find the voltage at the lower multiplier, uncheck the higher multiplier. who already have a stable voltage.
(cpu, it will only work at max clock multiplier in the earlier check)


stability Test

1. Open Orthos and HWMonitor
2. Open the tab "CPU Info" in RMClock (to see the temperature and cpu clock)
3. Orthos set to "Small FFTs-stress cpu".
4.Start Orthos for 45 minutes.

* On the stage who seek a stable voltage, 10-15 minutes is sufficient.

* If the voltage is not stable, then your laptop will experience a BSOD (Blue screen) or Error on Orthos.
do not panic if it appears the BSOD, restart your laptop normally.

* After making finding the voltage is unstable, increase the voltage 2 level and then run back to stability tests
(Voltage is stable so it will then be used for the multiplier).

* For stable voltage is recommended to run a stability test for longer, 1-3 hours.


save and apply

after all multiplier gain stable voltage, RMClock settings at windows startup:

* Profile tab in RMCLock: select "Performance on demand" for Startup and current, click Apply.
* Tab settings: Check "Start minimized in the windows tray" and "Run at Windows startup", click Apply.

nvidia switchable

Graphic systems such as the switch has been implemented on some Sony Vaio notebook that came out was almost a year ago. This notebook is to use two VGA, namely Intel and Nvidia Geforce. But, on this Vaio notebooks, the switch is done manually. There are two modes of selection, namely the Speed and Stamina. In Speed mode, VGA GeForce active, whereas in Stamina mode using Intel GMA 950.

for trouble shooting switchable vga graphics

from ATI HD 5650 to Intel HD, but I cannot switch back to ATI. Then I have to go to bios and made discrete mode only then reinstall ATI drivers and so on?

It started working properly then I installed latest programs and drivers from acer site for my model like VGA_Intel, Application Intel, ePower Acer and update BIOS. I guess it was all about intel drivers and their ability to switch graphic back to ATI.

Windows XP Service Pack 3 does not support Switchable Graphics Technology. This is a limitation of the Windows XP operating system. VGA driver cannot be loaded until the display mode in BIOS is changed to Discrete.

To resolve this, please follow the below steps.

1. Update the BIOS to version
The BIOS can be downloaded from the Drivers and Downloads area.
2. After the BIOS has been updated, reboot the system and press F2 to enter the BIOS setup menu.
3. Change the "Switchable graphics" setting to "Discrete".
4. Save changes and exit.
5. Reboot the computer. The ATI VGA driver can now be installed.

boost your Laptop

For the most part, it is probably safe to say that you do not use everything that is downloaded or installed on your computer. If you do not, then these files are simply sitting in the memory of your computer just taking up space. When these files take up space, they are slowing down your computer. If you do not need all of this information or use all of it, then what is the point of letting it stay on your computer where it takes up space and slows down your computer? If it is not needed or is not used, it is best to remove it from your computer instead of letting it alter the performance of your computer.

However, just because your computer is a few years old does not mean that you need to go out and purchase a brand new computer. Over time, you install and download a good bit of information on your computer. Some of this information is removed over time but it is likely that some of this information is still lurking on your computer's memory.

When you purchase a new computer, the speed of your computer is at its fastest. However, over time you will notice that the speed of your computer will begin to slow. The speed of your computer will continue to deplete over time the longer that you have the computer and use it.

A great way to speed up a computer is to remove unused and unneeded information and files. This can be done by cleaning out the registry of your computer. Your registry is like the brain of your computer where all of the files and information is stored. However, if you are not using all of these pieces of information or the files, it is just taking up space in the registry. By removing the unneeded or unwanted files, you are making room in your computer's registry.

You may not realize how much information is stored in your computer's registry until you clean the registry out. Once you get a look at how much information is removed, you will realize why the speed of your computer was becoming slower over time. Performing regular registry clean ups on your computer is a great way to clean out your computer of unwanted or unneeded information that may be slowing your computer down. By performing a registry clean up, you are less likely to have trouble with the speed of your computer slowing down.

how to buy new hardisk

A study of Storelab, a repair company data recently released important information about the age of the hard disk. Data collected in the long term, according to usage and damage the hard drive they found. This report is a matter of controversy because many defective or damaged disk made by the vendor manufacturers, and the importance of data stored on computer hard drive.



Computer users, especially the complete computer buyers never know what brand of hard drive they use. Sometimes a lot of buyers like the long warranty period, and ensure that their hard disk will be replaced if damaged. Damaged hard drive will be replaced, what about the fate of important data. Can be answered by the manufacturer of the hard disk.
Hard drive for home PCs may lose important data such as music or photo files into private collections. But for professionals, important data that made many months could have been lost by damage to the hard disk.

How long can hard working age. The answer is never the same. One vendor can generally reach 3.5 years, but there are others only up to 1.5 years. Capacity and model and distinguish the quality of a service life of a hard drive. About the hard drive maker manufacturer, the user, the percentage of damage and service life.

In general there are 6 major manufacturer of hard drive maker Fujitsu, Toshiba, Hitachi, Samsung, Seagate, and Western Digital. In research conducted more than 4000 hard disk unit with 3.5 and 2.5 inch format. Storelab perform comparisons of data collected according to the classification of products, brands and capacity and model.

According to iSuppli, the use of disks in the computer market. The world sales leader Seagate hard drive, followed by Western Digital.
According to data obtained from records Storelab damage the existing hard drive on them. Greatest damage occurred on the hard drive is Seagate's largest product who led the drive sales in the World. Almost 2X from the existing hard drive market share, equivalent to 31%
Although the use of disk in Russia amounted to only 40% of the entire hard drive Seagate brand. But the damage hard drives from other manufacturers are much lower, such as Hitachi and Western Digital are only listed 11% below it.

Designers such as hard disk drive maker Engineers may say they are capable of working hard for many years even decades. But the conclusion that they do is done on the basis of numbers, and not the actual test. Given a new hard drive may not sell after many years of trials conducted to obtain MTBF figures.
What is surprising from the data in the can by StoreLab. There was an old hard drive is only 1.5 years only. While the oldest works of Hitachi and Western Digital brand, able to work up to 3.5 years before the indicated damage.
From brand Seagate 7200.10 only type that is able to work more than 3 years. Samsung and Toshiba / Fujitsu also the same fate, only work within 1.5 to 2 years and into StoreLabs to do forensic data.

The conclusion of each hard drive data destruction

Seagate

* 500GB to 1.5TB Seagate Barracuda 7200.11 type. Achieve 65% of hard drive damage that goes into StoreLab to be repaired or saved data. The biggest damage occurred at Seagate 7200.11 Firmware damaged by displaying code 000000CC.
* Seagate 7200.10 type, more resilient than 7200.11. Damage only reached 35%.
* The damage occurred on the hard disk drive motor, especially on the axles. The greater the number of platters will shorten the life of the motor drive. And ends with the death of the hard disk.
* Hard drive that works excessively and continuously, into one category of causes of death drive. Signs of damage on the hard drive experiencing motor drives, hard drives will increasingly loud noises and excessive noise plus vibration.
* Seagate Technology hard drives trying to fix the 7200 series. And spend 7200.12 more reliable.

Western Digital

* 500GB hard drive turned out to hold up to 3.5 years. The remaining 41% broken is the type of construction.because 500GB platters more typically more vulnerable to damage. Even some models of damaged before the age of 2 years.
* Characteristics of damage to Western Digital is located when the process of writing and reading data on hard disk platter plate. That is the hard drive head is damaged, and become the hallmark of Western Digital hard drive.
* Other conditions are the temperature of the hard disk. Damage occurs when the hard drive has to work at a temperature of 45 degrees more. Hard drive becomes too hot.
* Western Digital makes hard drives with better shaking endurance. Creating motor shaft system is made separately with the cover disk. Do not ever close the hole on Western Digital hard drive. The unit, Western Digital hard drives are reliable. Including electronic and mechanical units used.



Fujitsu , Toshiba and Samsung

* Most of the models are checked for 2.5 inch format, especially the hard drive for notebooks. The average age of 2 hard drive manufacturer is reached 2 years.
* The most common problem on the Toshiba / Fujitsu is a pole clamp as drives in the form of a damaged bearing service life. Because the cover is very thin eroded, and the lubricating fluid evaporation occurs. This makes the friction in the socket, then rupture and destroy the axles.
* Other Damage occurs when the head drive start rubbing and damage the hard disk platter. Easy character, would sound like faint small sound. Then the hard drive will not be detected anymore by the computer BIOS. Certainly the data in the hard disk is unreadable, missing alias. It is generally a phenomenon at the Samsung hard drive.

Of the four major brands, best hard drive is Hitachi.


This was stated by StoreLab. 200 hard drive received and asked to be corrected to note this hard drive repair companies. And none of them have failed because of design work Hitachi hard drive itself.

* All the damage that was found was the fault of the user.

But do not make a benchmark that data StoreLab into alloys in selecting the hard disk. Because many other factors that are not visible to general public. Figures damaged hard drive can be smaller or larger view of this study conducted in eastern European countries, which are generally much cooler and the product is only marketed the country.

This figure is a collection and research conducted by StoreLab on damaged hard drive and tried to rescue the data carried by them.

Securing performance hard drive to work longer.

* Avoid hard work on high heat.
* Not putting hard work in bad conditions, such as the haphazard layout of the hard drive inside the computer or notebook.
* Using the anti-vibration components to protect your hard disk.
* If you need to pair the temperature sensors to monitor hard drive heat.
* Always provide a backup hard drive for data backup, if your data is important.
* Know the weaknesses of each product from the manufacturer.
