K6-2 550

[chill]

Right now I have:

CPU - K6-5 550MHz
MBoard - AOpen AX59 Pro
2.4V, 5.5*100MHz

Now I look at the MBoard manual - I see some possibilities to clock:

100MHz --> 112 MHz and 124MHz

do I do it right away or ???

also Voltage can be rised from 2.4 --> 2.8 (2.9, 3.2, 3.3, 3.45, 3.52) But my mind says - "don't tuch voltage !!!"

CPU Frequency is maximum 5.5 (can be lower like 5, 4.5, 4, 3 ...) so Frequency cannot be bigger as it is right now.

OK - what do you suggest - do I jump from 100MHz to 112MHz and if it work then 124MHz?

Temperature is right now 38 degrees (HW monitor util. says)

Thank U - in advance

just in case - I say I have:
RAM - DIMM 160MB PC100MHz and
voodoo 3 2000 AGP 16 MB

OK - thanks - again

With an AMD K6-2 and above you can set the clock multiplier to 2 and the CPU will be set at a multiplier of 6........giving you 600mhz. However, the K6-2 and 3's are not very overclockable so you would be lucky to get it out of it. On the K6 line of CPU's it's a little risky to up the voltage since these processors are so close to their limit anyway. With the PC100 sdram you most likely won't get the FSB overclocked reliably. If you tried it and it won't post then try underclocking the clock multiplier to 5.0 and upping the FSB to 112mhz (giving you 504mhz). This will give you better performance than 550/100 anyway. As long as you don't mess with the voltages too much you won't damage anything.

clock multiplier to 2 ???

where is this? what is this? Is it the MHz that is right now 100 or is it Frequency that is 5.5 - or what? - sry

[berkeljm]

It is the 5.5 setting. The 100 is your Front Side Bus (FSB) setting. The clock multiplier is the CPU (processor)Clock setting.

OK - now it's 5*112=560MHz (+10MHz) works
ready to test 3DMark
Do you think I should now rise 5 --> 5.5 or 112 --> 124

Looking back at my original post...I made a mistake. I said that it would give you 504mhz if you set it 5.0/112. Obviously that was a mistake. I had 4.5 stuck in my head. Ok, now back to your question. I would leave it like it is for now and see if you get any weird problems like rebooting for no reason or lockups. If then you still don't have any problems try and up it to 5.5. I don't think it will work though. Regardless of how much you overclock it I can't stress enough about making sure you have SUFFICIENT COOLING!!!! Case fan, exaust fan, good processor fan, and any other fans you want. With the FSB set to 112mhz you are also overclocking your AGP bus, PCI, bus and memory bus. This may not cause problems right away but after running a 3D intensive game it could lockup or reboot. Try it like it is (with proper cooling), and see how that works before you try anything else. Upping it to 5.5 is not going to give you much of a performance boost to deal with the hassels it could (most likely) cause. Upping the FSB is where the performance gain (that you will notice) is.

jes 3Dmark was better thn before - I dont remember what it was before, but now it was = 1324

OK jes - it seems that AGP ang stuff (BUS-es) are also faster.

I'll see what happens - I don't know - anything about coolers - but my cooler is quit big (bigger than it was - when I had CPU 400 - and I also have put this glue or special liquid - U know)

I'll see if it works I still dont know if I shoult next rise
112-->124*5=620 or
112*5-->5.5=616

OK I am glad also if it works - how it's right now.

NEXT step - my voodoo 3 2000 AGP 16 ? Can U halp me in this one also? Do I need some programs or what?

Thanks

Even if you underclock the processor to 4.5 I don't think it will boot with the FSB at 124mhz. At 124mhz you are seriously overclocking the AGP bus, PCI bus, and the Memory bus. I do not recommend this. I would also get at least 1 case fan. As far as the video card. There are some overclocking utilities for the voodoo 3/2000 at WWW.3Dfiles.com. I never got my voodoo 3/2000 to work reliably past 185mhz..........factury default is 166mhz. That is without putting a fan on the heat sink but even with a fan I don't think it would go much higher than 190.

OK - I tried to jump now from 5*112 --> 5.5*112 computer started - but W2K did not 🙁

now I'm back in 5*112 - but I was wondering that ...

1) I have right now DIMM PC 100MHz - will it be faster if I replace it with DIMM PC 133MHz ???

2) will it be faster if I replace W2K with millenium?

3) will millenium boot up with 112*5.5 ?

Thank U

I really doubt that the 124MHz bus will work, especially with PC100 RAM. You may be able to get the 5.5x112 to work. In an earlier post, there was an error. Only the new K6-2+ and K6-3+ have the option to set your multiplier to 2x and get actual 6x. I believe you are talking about an original K6-2 which doesn't have that ability.

This statement is completly false. All Amd cpu's with the ctx core will recognize the "2" multiplier as a "6". Thus any k6-2 350 and above will support this feature.

A little bit of knowledge is a dangerous thing!

 

[berkeljm]

I would have to agree with Incogneto since I have a K6-3 450(NOT a +) that would post with the multiplier set at 2(6) giving it 600mhz. It would lock up right away after the post but it still posted at 600mhz. I also tried lowering the FSB to 83mhz at a multiplier of 6 but it would not run windows reliably. Even still, I would agree with you that the PC100 will cause more of a problem.

supposedly all k6 2s since the 400 have the 2/6 multiplier swap.
my 450 did.

Some Socket 7 motherboards have changeable multipliers for AGP and PCI and Mem bus.

Normal:

5.5x100MHz = 550MHz
AGP: 66MHz (2/3), PCI: 33MHz (1/3), Mem: 100MHz (1/1)

If the motherboard supports it:

5.0x124MHz = 558MHz
AGP: 62MHz (1/2), PCI: 31MHz (1/4), Mem: 124MHz (buy PC133 RAM)

This should give a performance increase. Depends on your mobo, though. Note on AGP: I've found that many modern vid cards (like geforce) run fine up to 83MHz AGP.

Opps. I meant 4.5x124 = 558. You could even try 4x133 = 533MHz or 4.5x133 = 600MHz. I doubt this would work, though
