I am thinking of upgrading an old Pentium 120 MHz computer with an amd K6-2 366 MHz chip I have lying about. Not sure about the board version (some OEM shite).
Now, I know that this chip will run happily at 400 MHz with the board multiplier set to 2x (chip runs at 6x when board sets multiplier to 2x) - and the board supports 66 MHz FSB. But, does the bios need to recognise this chip for it to work? Has this got any hope of working?
Will have to check on voltages - anyone remember the voltages required for Pentium chips and whether this is close enough to that for the K6-2 chips. I've got an Athlon XP heatsink lying about too - so there will be plenty of cooling.
Anyone got opinions other than throw the onld machine in the bin?
Finally, nothing happens if you run your CPU on lower FSB except that performance drops (obvious, isn't it?). Good cooling like the one you mention will allow you to reach higher frecuency easily. Also if you have 2.4 volts or even 2.8 volts instead of 2.2, the K7's HSF can make the system run.
Oh yes, one more. Maybe your mobo has a maximum of 66Mhz, but some software programs could give you higher FSB if you have the right clock generator. Can't remember the names, look around overclocking sites. In my case I'm running a K6-2 500 at 6x83, stressing a little bit PCI bus, but runs ok.
Says it does not support even MMX cpus - so think I might be out of luck with the K6-2 cpu. I might just pop this into the baord and see if the chip dies - or tell my sister to buy a newer computer - she's got plenty of cash anyway.
Hi! I believe it can be done! I've installed a K6-2 400 AMD CPU on my old Pentium 133 System and it worked, but with the help of the Powerleap PL-ProMMX Adapter. The reason you'll need that adapter is the different core voltage that the specific processor needs (2.2V if i remember correctcly) apart from the 3.3V standard CPU voltage. My motherboard was a SOYO 5VA2 and the powerleap adapter along with a K6-2 400 AMD CPU run just fine!!!!!!!!You are right about the 2X multiplier recognized as 6X from the AMD CPU and if your board supports 66Mhz FSB i think that it can be done, but first of all visit www.powerleap.com site to see if your motherboard is compatible and can support K6-2 400 along with the adapter. It is possible that you may need to flash to a newer BIOS version.
Hope this helps.
You have most of the information you need, but like the other guys said, you have a single voltage board. Someone mentioned the $50 PowerLeap adapter, well, you could buy a new motherboard for less than that.
Most boards that did support dual voltage with 2.8v or less vcore would work, even without BIOS support. But yours won't.
