You can set the jumpers to:

JB2 - Pins 1 and 2
JB1 - Pins 2 and 3


Your CPU has a FSB of 1066 MHz. (See )

The system uses a "4" multiplier, so the freq. for the above settings would be 800 - 1066 MHz.

You can overclock the CPU at your own risk using the other settings. I would not recommend it, but many do. Better safe than sorry.

Thanks for using Fixya.

    BTW this is what Intel says about overclocking:

    Reliability Issues

    Overclocked processors can produce unpredictable results or system instabilities, which might not be readily apparent. The life of the processor may also be shortened. The expected frequency is the frequency at which Intel warrants the reliable performance of the processor.

an JB1 and JB2 fues boxes.
its not in the PDC
Fuse 1 is in JB2
but he horn relay is in JB1

now you will ask me where are the boxes... sigh..
the operators guide covers that. and i dont do, that,
2006 is still online for free, 10 year range, why not get it while you still can?
here it is, get it read it and read the fuse pages.

Find the voltage setting from MSI then enter your UEFI BIOS. switch to Advance find the Video card section and update it to your manfuctures settings. this is not Over clocking it is a simple adjustment. hare are the recommended speeds for your card.

810 MHz Core
1024MB DDR3 1334 MHz / 1200 MHz / 1000 MHz Memory

adjust to voltage to lower or raise the MHz

How can I fix the new CPU on system? From bios or from jumpers on board?

Hi erkankrtkaya,

If you installed a new CPU on your motherboard, did you check with MSI to see if that board supports your new CPU? HERE will give you a list of support CPU's and information about the board.

Good Luck

Sy p4vgm won't boot when I set the CPU jumpers to 133 MHz instead of 100 Mhz.

Back to the jumpers again... Don't you know that those jumpers can cause your MB to fry? Your most touchy point is the temperature of the CPU chip. Do you have a way to see what it is when in the CMOS setup? If you do, OK! Maz temperature is about 55oC, even though they say 60oC. When you raise the voltage with the jumpers, you could create so much heat that your CPU chip will commit suicide. In your case there is protection against excessive heat. This probably is made for a much faster and more expensive computer. Once you have a way to monitor the temperature, carefully, you can try the higher frequency and WATCH the temp. You can increase the voltage to get up to two or three times the original frequency. This is called "overclocking". You will probably be requird to rebuilt the entire cooling tower, over the CPU socket, especially you will need a new and more powerful blower... One can get some extra life from an old computer, but now computers rae cheap when it comes to speed. Please let me know what are your decisions... That is how I am graded... Thank you for considering our help worthwhile!

How to get my CPU to run at the correct speed

Your FSB should be 400 MHz for the Athlon XP 3200+ processor.
CPU-Z shows your core speed at 1320 and your FSB at 241. If you multiply those numbers by 1.66, you get 2200 and 400. So all you have to do is get the board to the correct FSB speed of 400 and your core will be right.
There are two MSI boards with the number CPU-Z gives you. Board 1
Board two

The AMD page doesn't show the core voltage for the older processors, they do for the current ones. I looked at the MSI site and didn't see their manuals online for the motherboards either, sorry. I'm not positive it was changed using a jumper though, you saw nothing in the BIOS to set it? If the jumpers are on the board they may be labeled FSB and you can try the various positions.

Hope that helps, good luck.

Overclocking Pentium 3 667 MHz on MSI MS-6198 Motherboard

some pentiums are locked at the set speed but there are no jumpers you have to alter the settings are in the bios eg the timing and there may be step ups to increase the processor speed, but remember you get far faster response times by fitting more memory as overclocking can cause overheating and crashes.

If the motherboard is new or you never set any jumper setting or you did not interfere any connection seeting their then you yo did not need jumper setting to seat the CPU.

The CPU you are going to use is very compatible in your mainboard so do not worry about the setting.

more about your setting click here for the usermanual of your board.

hope this help, melnavz

CPU installation


on the mobo there should be a little table next to a set of jumpers that tells u what jumpers to set for the multipliers. These days this is done in the bios but if your board is old (P3 which it is) there should be some white set of jumpers about 3 in a row near the cpu with a little table printed next to it. You should set it up so the multipliers adds up to guess is you should double what you have now to get it to 900 which is closest u are going to get

good luck
