This should also work on an AX5 or an TX5 which supports 2. The major improvement I made over previous solutions is that I decided to change the motherboard to generate Abit PX5. It was marketed as an overclockers dream, but I've always found my processors to be rock stable up to a certain setting, and unusable beyond that, so I never have had to change the settings after I had closed the computer. There are two different and Abit PX5 fully compatible AMD K models. So are all the later models. The CXT core needs a bios modification to run optimally, otherwise it is detected as an old core, but would actually run slower than the old core.


According to Abit PX5 manual however, "reserved circuitry supports future sixth generation CPUs". Too bad I never was able to find out what that was I have found an unused transitor near the voltage regulator, but as far as I Abit PX5 tell it is not even connected. Abit decided under Intel pressure? So, they dropped all support bios and softmenu upgrades for socket 7 motherboards.

Problems you might encounter during the upgrade 1. The motherboard does not supply 2.

The voltage regulator might not deliver enough current. The bios and softmenu don't support the processor.

Setting the correct voltage Running a processor at the correct specified voltage Abit PX5 crucially for the correct working of the processor. If the voltage is too low, the computer will crash sooner or later, especially under heavy load or when it gets hot. If the voltage is above the absolute maximum voltage, parts of the processor core burn out, rendering it useless.


The specifications for all AMD K6 processors include a margin of. If you have a 2. You do this is completely at your own risk! It is not likely though that you will kill your processor using 2. If you like to walk on the edge, and plan Abit PX5 upgrade in the near future, you might see how Abit PX5 your processor can run at 2.

I would suggest using extra Abit PX5. Be aware, the overvoltage might be enough to kill your processor at the first try! All other 2. The motherboard sets the processor voltage Vcore by setting the voltage divider for the voltage regulator input Vin according to the setting in the softmenu which is probably stored in cmos. The voltage divider consists of two fixed and six 'switchable' resistors which are switched 'on' 1 by transistors Q The voltage regulator adjusts Vout Vcore so that Vin is 1.

The resistances shown Abit PX5 this text are the ideal combined resistances of the transistors and the resistors! While these are not Abit PX5 actual resistor values, they help to clearify the workings of the voltage regulator.

Unfortunately, this is not so simple, unless you are an expert in reverse engineering. Abit PX5 next simplest way is to see where the softmenu settings are stored I assume in the cmos, as this seems to be the only non-volatile memory on the motherboardand change the settings there. If this is in cmos however, you'ld Abit PX5 have to find the specific value, then find what value you need and store it, and then calculate and store the new cmos crc value.

Abit PX5 instead, I decided to just change the resistor values to get other voltages. Like the newest revision of the AX5, the Abit PX5 from ABIT is in no way impaired and functions above and beyond the call of duty. When ABIT  Socket Style‎: ‎Socket 7.
