Overclocking!! OK, now I know how to get to BIOS, but it doesn't let me overclock my RAM. Do I need to flash Bios or is there another way to do it?? thanks for any responses

    The problem is that when I do go to BIOS it doesn't give a options to go to "setup" to change the voltage, FSB, and the timing.

    From the program cpu-z ,

    Motherboard

    Manufacturer: TOSHIBA

    Model: Portable PC Version A0

    Chipset: intel i855GM/GME Rev.A2

    Southbridge: intel 82801DB (ICH4-M)

    LPCIO: SMSC



    BIOS

    BRAND: TOSHIBA

    VERSION: VERSION 1.50

    DATE: 01/26/2004



    ALSO I UPGRADED FROM A 512 DDR 266 PC2700 TO A 2GIG DDR 400 PC3200

    BUT IT'S SLOWER THAN THE PC2700

It should be in your BIOS settings. You could flash it and see if they appear.

Hope the fans are working good.

Help me overclock ASUS P5GC-MX/1333


LOOK IF A BIOS PASSWORD IS SET.

I cant overclock my system but i go to bios now whati had to do


The BIOS. Overclocking is best done in the computer's BIOS (Basic Input/Output System or Binary Integrated Operating System). There are also some motherboards that let you do a basic increase in power by setting a jumper, but this is dangerous and you have no real stability control.


There are some software programs available which allow you to overclock inside the operating system, but the best results are achieved by changing BIOS settings. Usually you can get into your BIOS by pressing DEL (some systems may use F2, F10, or Ctrl-Enter) as soon as your computer begins the POST

(Power On Self Test - when it shows the RAM size, processor speed, etc.).


Here, you can change your FSB (front side bus), memory timings, and your CPU multiplier (also referred to as CPU Clock Ratio).

Clearing your CMOS. Sometimes, an overclock can become unstable. If this happens, or your computer will not boot, you will need to reset the BIOS back to default and start over again.


This is done by clearing the CMOS (a small piece of memory on the motherboard which stores your BIOS configuration, and is powered by a small battery). Some newer motherboards will bypass user settings in the CMOS if the computer fails POST (often caused by a faulty overclock). However, most motherboards require a manual clear.


This can be done in two ways, depending on your motherboard. The first way is by changing the position of the clear CMOS jumper on your motherboard, waiting a few minutes, then repositioning the jumper to its original place.


The CMOS Jumper

The second way, if your motherboard doesn't have this jumper, consists of unplugging your computer, removing the little CMOS battery, then pressing the power button (your capacitors will discharge), and waiting a couple of minutes.


Then you have to refit the battery and plug in your computer. Once your CMOS is cleared, all BIOS settings are reset back to default and you'll have to start the overclocking process all over again. Just so you know, this step is only necessary if your overclock becomes unstable.


Locked or Unlocked. The first thing to know when you start the process of overclocking, is whether your processor is multiplier locked or unlocked.

To check whether your CPU is locked, lower your multiplier via the BIOS one step, for example from 11 to 10.5. Save and exit your BIOS and your computer will restart.


If your computer posts again and shows the new CPU speed, it means your CPU is unlocked. However, if your computer failed to post (screen remains black) or no CPU speed change is present, this means your multiplier is locked


Multiplier Unlocked Processors. Usually, your max overclock is limited by your memory, or RAM. A good starting place is to find the top memory bus speed in which your memory can handle while keeping it in sync with the FSB. To check this, lower your CPU multiplier some steps (from 11 to 9, for example) and increase your FSB a few notches (e.g.: 200 MHz to 205 MHz).


After this, save and exit your BIOS. There are a few ways to test for stability.

If you make it into Windows, that is a good start. You can try running a few CPU / RAM intensive programs to stress these components. Some good examples are SiSoft Sandra, Prime95, Orthos, 3DMark 2006 and Folding@Home.


You may also choose to run a program outside of Windows, such as Memtest. Load a copy of Memtest onto a bootable floppy, then insert the disk after you have exited the BIOS.

Continue to increase your FSB until Memtest starts reporting errors. When this happens, you can try to increase the voltage supplied to your memory.


Do note that increasing voltages may shorten the life span of your memory. Also, another option is to loosen the timings on the memory (more on this a bit later). The previous FSB setting before the error will be your max FSB. Your max FSB will fully depend on what memory you have installed. Quality, name-brand memory will work best for overclocking.


Now that you know your max FSB, you'll figure out your max multiplier. Keeping your FSB @ stock, you raise your multiplier one step at a time. Each time you restart, check for system stability. As mentioned above, one good way to do this is by running Prime95.


If it doesn't post (reread the section about clearing the CMOS), or Prime 95 fails, you can try to raise the core voltage a bit. Increasing it may or may not increase stability. On the other hand, the temperature will also be increased. If you are going to increase the core voltage, you should keep an eye on temperatures, at least for a few minutes.


Also note that increasing voltages may shorten the life span of your CPU, not to mention void your warranty. When your computer is no longer stable at a given multiplier setting, lower your multiplier one step and take that as your max multiplier.


Now that you have your max FSB speed and your max multiplier, you can play around and determine the best settings for your system. Do note that having a higher FSB overclock as opposed to a higher multiplier will have a greater impact on overall system performance.

How can i overclock a insydeh20 bios


you cannot overclock using insydeh20 as the features that allow you to do this have not been written within the BIOS.
there are only two ways you could possibly perform an overclock.
One is to either flash your current BIOS with a different BIOS that does have these features but this is VERY RISKY and it could brick your device.
OR
use a program called setfsb or clockgen. NOTE: if your device is recently new (within the last 4 years) it will more then likely have a restriction on the motherboard preventing the CPU to be overclocked. The only way around this restriction is to perform a PLL pin mod which again is VERY RISKY and if not done correctly will cause unrepairable damage to your motherboard.

Overclocking


Overclocking is set from the BIOS configuration. Not all BIOS allows overclocking, it may need a BIOS upgrade.
Check the ASUS WEB site for your model motherboard.
Overclocking the CPU (ie running at a higher clock speed) and increasing Frontside bus speed will give better performance BUT there is a downside too, if you overclock too high you could overheat the CPU and it could fail.

Overclocking locked on 945gct-m2 mobo


There is no overclocking settings for this motherboard, the CPU speeds and core settings are automatically determined. You may be able to find a modified bios somewhere, but i would strongly suggest this not be done. A bad bios, or bad flash can essentially turn the motherboard into an expensive paperweight.

How to overclock my motherboard ?


there are 2 ways, overclocking using the bios to over clock the memory ( ram ) and also the processor ie changing the multipliers and other tweaks ( which should be in your motherboards manual ) that or using jumpers which are physically on the motherboard but later motherboards use the bios to tweak / over clock your computer.

BIOS problem!!


Why do you want to overclock it? Have you changed the cooling system? Overclocking might fry your processor if the cooling cannot keep up with the heat. Does your motherboard support overclocking? The option might be locked. There might be a jumper on the board that you have to mingle in order to enable that setting.

Overlocked my Intel Pentium 4 3.00 Ghz


You have to go into your bios and see what your front side bus and memmory speeds are. If you overclock you cpu, sometimes you need to underclock your memmory. Say step your memmory down to 333mhz and overclock your front side bus(fsb).
Normally your fsb is 200 and only increase it by mhz. Restart, go into windows. and see if it is stable.

I always use cpu-z and gpu-z to check all of my hardware settings. I use ati tool to overclock my x1950 and it is great. There really isnt any good cpu overclocking tools because its better to do it in the bios.

Do a specific search in google for your processor and overclocking.
