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.

com surrogate error libavcodec.dll in windows 7

When try to open " My Pictures" in Windows explorer it shuts down and starts again. Vista or seven then reports that it is a "FFmeg problem" as I have no clue what FFmeg is, I can now not open my pictures folder. Can someone PLEASE tell how I can rectify this problem..
This is the report from Vista or seven

Computer's Need Registry Cleaned

What is the registry of a computer?
Information for programs and hardware are located in the computer's registry. The registry truly is the brain of the computer. Every piece of information is stored in the registry. With this in mind, it is easy to see why the registry would need cleaned at some point or another. If every bit of information goes to the registry and you have had your computer for years, then that is years worth of data and information that is stored in the registry.

Before you can understand the importance of cleaning your computer's registry, it is important to know what the registry of a computer is and what it does. The registry of a computer is like the core of the computer. The registry is the brain behind the operation. There is not a single piece of that computer that would function correctly without the computer's registry. The registry of a computer is like an archive building. Every piece of information and every file that has ever been on your computer is stored in the registry of your computer.

It is likely that you do not access all of the information in your computer's registry anymore. They may be information left over from programs that are no longer on your computer. There could be duplicate files in the registry. This is all unused and unneeded information stored in the registry. This is why it is important to clean out your computer's registry. These things no longer need to be in the registry. At this point, all these things are doing is taking up space and slowing your computer down.

The registry clean up scan will allow all of the unused, unneeded, unwanted, or unnecessary bits of information to be removed. This is how:

- The scan will be started on the computer's registry.

- The registry is scanned and all files and information that is broken or corrupted will be fixed.

- When information and files are located that are duplicates, they will be deleted from the registry.

- When the scan finds unnecessary bits of information, it will also be deleted.

Deleting duplicated information or folders and deleting unnecessary or unused bits of information will allow your computer to have more space and will also allow your computer to run faster than it previously had before the registry clean up scan was performed.

Give it y try and you will be impressed.
