Upgrade amd k6-2 500MHz

[bdhelm2]

I just upgraded my cpu from amd k6-2 200 MHz to k6-2 500MHz it still shows at 200 mhz . How do I get it to read at 500mhz, there no bios settings where I can change cpu speed. This is a old Power Speck computer I use for backup.
Any ideas
Thanks, Bob

Check the motherboard for jumper settings. are you sure your board supports a 500 properly? the settings should be 5x100.

Have no manual or info for this board

Assuming that BIOS actually supports (and reports) a cpu up to 500 Mhz, you will find some motherboard jumpers. You will need the manual to get the jumpers set correctly. The fsb should be settable to (hopefully) 100Mhz. Then, you can set the jumpers for a 5 multiplier. If that board only supports 66 Mhz fsb, then you will need to set the multipliers to 7.6 to obtain 501 Mhz.

I expect that you will discover that the BIOS will report less than 500 Mhz however with-out an update..if there is an update. My backup is a K6-2 500, running on an older ASUS board. The BIOS is the original and reports the frequency as 400 Mhz...however, once in Windows...utilities there say 501 Mhz..so, I don't worry about what the BIOS reports.

So.. see if you can find a manual on that board and decide on which jumper setting you will need to get that 500 going at 500 Mhz.

The CPU Core voltage will be 2.2 volts.. I suspect that is currently what it is already set to.

You can try one of these programs to try to identify the board:

Can't help you much if you don't even know what kind of hardware you have. :(

my k6-2 mobo has a dual in line switcg array, different switch setting apply a different multiplier. Look on the board a rectangular block with six switches on it, only you can crack the code if the switch is there.

000001
000010
000011
000100
000101
000110
000111
001000
001001
001010
001011
001100
001101
001111

and so on and so on until you reach

111111

That should keep you busy, LOL, but it may the first three is the speed 66,83, 100, and the secon is the multiplier, 2,3,4, etc. good luck

The highest multiplier in the k6s was 6x using the 2x setting on the motherboard.

Well..no manual, I suggest you get another motherboard..one that comes with.. or you can download the manual. Those jumper setting can be rather cryptic silk screened on the board itself.

Lotsa luck!

If you can't find a manual for it you might be able to read the FSB and multiplier settings off the board if your eyes are good. If your settings are limited to 75 or 83 FSB and/or multipliers of 3 or 4, you can always set the multiplier to 2x because on that processor the 2x multiplier is remapped to 6x. So, if you can muster an 83.3 FSB then you will have 500MHz.
Updating the BIOS will likely be necessary to maximize results.
When you are looking for the FSB settings on the mobo, look for a table with numbers on it like 50, 60, 66, 75 and possibly 83 or 100.
The multiplier table might be easier to find as it will have numbers like 2, 2.5, 3, 3.5, etc and may be designated "frequency" or something like that. It may also be marked as ratios like 2/3, 1/2, 1/3, 2/5, etc. 1/2 would then the 2x (now 6x) multiplier.

Yes. The jumper-multiplier table usually are printed in the motherboard itself. Sometimes, jumpers for fsb is in separate table also in the mobo. Get a cheap student magnifying glass for it.

Going from a 200 to a 500 you better check the board for your core and i/o voltages. Probably going to need to change those as well.

Should say on the top of the chip what they are but you will have to look on the mobo for screened info on what jumpers do that as well.

I personally have my doubts that board can jump that far. 300 mhz big step for old boards. :(

that 200 cpu runs at 66mhz so it would seem you're running now at 2.5 x66 maybe? and the guys are right - ge the specs on that mobo somehow - and you sure it ain't a Power Spec system -here (http://www.powerspec.com/) - the other is a MAC site.....

normally then, your pins for multiplier would move up or down, or away from the end of the pin setup in hopefully in one pair increments so you might try one pin down one pair (be careflu - you really ought to get the mobo specs), which means maybe you move one set down one pair as to the multipler, but the fsb should be somewhere else on the board normally....

but crossed's up's right - I'll bet the or mobo or jumpers won't let you make that leap, the voltages are probably different, that chip is supposed to run (I think at 5x100) and by my recollection they weren't forgiving using other settings, even if you have 83 mhz - I did overclcok successfully either a 400 or 450 (can't rememeber) to 500 that way.

I doubt that mobo has an FSB of 100, and last board I used with an 83mhz fsb setting (it was a pcchips board), and the 83 mhz setting wasn't documented, but it was there....gave me problems with pci bus as it ran at 1/2 FSB, which could cause a problem or two with your pci peripherals -I seem to recall frying a burner that way, but I was o'clocking :eek:

good luck - those chips are dirt cheap, maybe run at the fastest setting the board will allow and just add some RAM, or get yourself another one - the the fastest AMD the board'll take.....:t

or a new motherboard, that way you get the manual free.:)
