Went to load new info into CPU regarding the LED's color. Inadvertently changed the numbers on several of the wrong parameters, before i hit the correct LED1 LED2 and LED3 I have heard each rigs is unigue in this function. Is there anything I can do,perhaps get the proper numbers for the proper parameters thru using identification on my rig ie serial number? Please advse me what to do HELP David a.

20 minutes worked then it just went black

Not a Solution but may help! Honestly more info is needed so We can narrow your problem down. Lets start with this. Note I havent looked up the manual for your model but This should help. Mostly Standard. Like traffic lights.

First, Locate your power Led, Note Color of Led. Red?(off) Green/Blue (on)Yellow (Standby). If you have a manual handy the Troubleshooting section describes these and what they mean.

1) If no power led is lit then, its either your power receptacle,(highly unlikely) fuse on power supply or power supply. Needs service.
2) If there is a power light. Note the color and if the led changes color or blinks after you hit the power button. ALSO,
B) Does the screen stay black, does it flash. or nothing happens? Note any changes in the led power light color and note it down.
If there is power and you still have no light, could be any of your boards. But we need to first verify power.

Hope this helps. Will

Hi, We have KEB F5 inverter on our machine model

If you are connected to the inverter with COMBIVIS, go to parameter FR.01 and enter a value of -4. This will set all parameters back to factory default.

You may be having an issue with the inverters software verison. As long as the inverters are the same part number, you should be able to download the parameters without any issue. There may be some unknown parameters but you should be able to hit ignore and keep on downloading.

Compaq presario cq62 won't start but the caps lock led blinks continuously and the wifi led remains on continuously, tried new cpu, worked for a while and started same problem again.

those are blink codes, learn to count them.
if you pulled the CPU i bet you that you used the wrong heat sink compound.
The CPU shuts off all by itself if too hot. your job is to get the fan working and the heat sink working and that thermal compound right.
as the blink codes we are not HP here, ever

How I can incease CPU Freq from 408 MHz to 1008 MHz

It all depends on two things;

1) That you can go into BIOS Setup, and change parameters.

Parameters such as;

A) The Front Side Bus speed. (FSB), or
B) The Voltage for the CPU (Processor), or
C) The Multiplier for the CPU (Processor)

Or there may be a Soft CPU option available for the above, in BIOS Setup.

Be aware that overclocking the Processor will also step up the FSB. Ram memory, and expansion slot devices, will cease to work if the FSB is too high. (Front Side Bus,

408MegaHertz to 1008MegaHertz?

That's a big jump. I do not think that processor in this technology age, is capable of overclocking this far. Plus IF it does, will not continue.

Heat will be a Big issue for one.
The pathways inside a processor are based on the nm architecture.
NanoMeter. 1 Billionth of a Meter.

[ Your processor was probably in the 250nm architecture technology. Today's processors are down to the 22nm architecture ]

With too much heat there is Electron Migration. The electrons jump off, or Migrate, from the circuit trace they are on, over to a wrong circuit trace.
Causes the processor to burn up.

Secondly there is also a limit on the performance of a Processor. Asking for almost 2 and a half times the factory setting, is asking for too much.

Plus the Processors are tested at the factory, and sent out. They only have to fall within a rather broad set of specifications, and can be considered okay for the consumer, or computer manufacturer.

The Processor you have may have been on the Bottom of the test range. Even if you have knowledge, of someone else getting this kind of performance out of the same model, it may be that theirs was one of the ones, on the Top of the test range.

Overclocking is done in SMALL increments, THEN tested to see if the computer works fine, over a 24 hour period.


Change the Voltage?
Change in no more than a .2 Volt increment. Then the 24 hour test. Everything's OK? Move up .2 Volts. 24 hour test.

Remember, Ram Memory operates at approximately Half, of the Processor's FSB.
The expansion slots are a lot lower.

Change values (Parameters), such as Voltage for the CPU (Processor) for one, and you change everything.
Too much, Ram Memory, and anything in an expansion slot, will not work.

What Processor is it?
What motherboard name and model number? (Or what computer manufacturer and model number )

Hello, I would like to overclock my AMD mt30 CPU 1600Mhz25wattTDP 64clockspeed/power ratio to that of a SempronML37 2000Mhz35WattTDP and 57.1 clock speed/power ratio? Do I just change the voltages in...

Due to the way you stated the above John, you seem like a guy that will understand the following;

Yeah know funny thing about overclocking;

1) You may have a good Processor that came off the assembly line that day, or it may be one that just squeezed past Quality Control. Push it too much, and it will fry. Trying to make it hit 2.0GHz all day long, every day, may just push it over the limit. Sure you may have read about, or even heard of someone who did it. How long? How long did the processor last at this overclocked rate?

2) AMD's run H-O-T. Not a good idea to push a Processor with overclocking (Which makes it run MUCH hotter) in a cramped laptop environment, with a low cooling capacity anyway.

3) Ram Memory typically operates at half of the FSB Frequency Rate ('Speed'), that the Processor does. (Front Side Bus)

To overclock you can;
A) Change the Voltage
B) Change the FSB frequency rate ('speed')
C) Change the Multiplier

If you change the Front Side Bus frequency rate too far, the ram memory will not work anymore.
Won't match.

AMD Turion 64 MT-30,

The Sempron you name is a Turion also.
Turion ML-37,

4) You have to have a BIOS Setup Utility that will allow you to change CPU parameters.

See this article?

No mention that overclocking a Processor shortens it's 'Life Span'
No mention that if overclocked too far the Ram Memory may not work.

No mention that an AMD processor runs HOT, and if you overclock you'd better have a lot more than the factory cooling. Plus not a good thing for a laptop anyway because of a laptop's poor cooling design. (Cramped small space, small fan, inadequate cooling thermal module)

No mention that the BIOS Setup Utility in your laptop may not have a CPU Soft option, or options inside that allow you to change the Processor's parameters.

No mention that you should go slow. Change parameters in one SMALL increment, wait 24 hours, and check the system. Looks okay? Change parameters another small increment. Check during a 24 hour period. Keep going until the computer starts messing up, then go BACK to the last parameter that checked out okay

Have I dissuaded you yet?
Just don't want to see someone fry their Processor, or computer.


The Turion MT-30 has a clock multiplier of 8 times. (8x)
The Turion ML-37 has a clock multiplier of 10x.

The Turion MT-30 uses 1.35 Volts (DC)
The Turion ML-37 uses 1.35 Volts (DC)

The Turion MT-30's Front Side Bus frequency rate is 800MegaHertz
The Turion ML-37's FSB 'speed' is 800MHz.

What options in your BIOS Setup do you have for changing CPU (Processor) parameters?
State back in a Comment. (Believe top right of your page)

No options?
Then try CrystalCPUID, or ClockGen,

When you say the CMOS is set to reset, this should not be the case for normal usage. and maybe the problem if left in the on position the system will not start (which sounds like your problem).

My external frequency is set wrong and should like to know what it is.Its an asus p4s8x-x hope you can help thank you

The Asus P4S8X-X has C.P.R.

CPU Parameter Recall

(Central Processing Unit, or Processor)

Restart the computer, and BIOS will set the CPU parameters back to the factory default settings.

Internal frequency rate times the multiplier = external frequency rate.

The Asus P4S8X-X uses Intel processors (Socket 478) that have either a 400Megahertz Front Side Bus, or a 533MHz FSB.

Since you did not state what socket 478 Intel processor you have installed, I cannot tell you what the external frequency rate is supposed to be.
(At maximum operating capacity)

Have you installed a different Processor?
Were you trying to overclock?
What led up to this?
