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 2. 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 Abit AB- PX5 AX5 TX5.


There are two different and not fully compatible AMD K models. So are all the later models. The CXT core needs a bios modification to Abit AB- PX5 AX5 TX5 optimally, otherwise it is detected as an old core, but would actually run slower than the old core. According to the manual however, "reserved circuitry supports future sixth generation CPUs".

Too bad I never was able to find Abit AB- PX5 AX5 TX5 what that was I have found an unused transitor near the voltage regulator, but as far as I can 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 is crucially for the correct working of the processor. If the voltage is too Abit AB- PX5 AX5 TX5, 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 to upgrade in the near future, you might see how long your processor can run at 2. I would suggest using Abit AB- PX5 AX5 TX5 cooling.

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 Abit AB- PX5 AX5 TX5 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 in this text are the ideal combined resistances of the transistors and the resistors! While these are not the 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. The 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 first have to find the specific value, then find what value you need and store it, and then calculate Abit AB- PX5 AX5 TX5 store the new cmos crc value. So instead, I decided to just change the resistor values to get other voltages. To measure the Vcore voltage, I measured the voltage at the Vcore side of one of the transistors.

When you don't place a processor, the motherboard automagically selects single-voltage mode 3. Set at 2. Some experimentation will be necessary to find the exact resistor values needed because of the different values of the existing resistors, the influence of the transistors and the tolerance of the resistors themselves!

To change the 2. The current for the processor The maximum current a processor needs depends primarily on the type of processor, the frequency at which it runs and what the load of the processor is. The first two are fixed, so the processor uses maximum current when all parts of the processor including MMX and 3Dnow instruction units are Abit AB- PX5 AX5 TX5 at full capacity.
