PCChips M599LMR Processor Voltage?

[Factor6]

Hi There,

My stock processor is an AMD K6-2 rated at 2.2 - 2.4v I'm upgrading to a K6-III+ that needs 2.1v My vendor says some mobos have a switch that controls voltage. Does anybody know if this mobo does, or where I would look? By the way, the processor I'm buying is overclocked to 600mhz and has a core voltage of 2.0v but needs 2.1v to get 600mhz. The vendor sells a voltage regulator if my board does not have a switch. I'd like to save the 50 bucks on the regulator though... Many Thanks!

The board has software controlled voltage, bus frequency and multiplier. Enter BIOS setup, put it to "manual" mode and set everything the way you need it, save and exit. THEN (!) power off and put the new CPU in. Visit BIOS again to check that everything stayed the way you set it. K6-III+ should actually require 2.0V or even lower. Read its top markings.

Awesome, Thanks!!!! The vendor who overclocked it, still don't know how that's done..., says I have to feed it 2.1v to get 600mhz... Anyway, thanks for the info, I think I'll post something about overclocking... Thanks again...

End speeds (450MHz in this case) are a result of a simple math procedure.

The speed of your RAM, or FSB (Front Side Bus), is the speed at which data passes through your RAM, and through your processor (in your CPUs generation). This number is 100MHz, and your end number is 450MHz at stock. Thus your "multiplier" is at 4.5, or the ratio at which your processor multiplies the speed of the data processed within its core. Therefore, you can increase the speed of your processor by adjusting either one of those numbers.

Thus:

4.5 x 100 = 450
5.0 x 100 = 500
6.0 x 100 = 600
etc...

or

4.5 x 105 = 472.5 (473)
4.5 x 110 = 495
4.5 x 120 = 540
etc...


Not knowing if your processor is "multiplier locked" I cannot know for sure if you can simply raise the multiplier for a higher number. However, no CPU is FSB locked, therefore you can increase the speed of your FSB to (insert number here higher than 100) to get to a higher speed.

This is the basics of overclocking.

Problems:

1. Increases in voltage are often necessary to pull off any kind of overclock.
2. Increases in the said voltage yields in heat
3. Heat yields in instability and potential damage
4. Voltage increases can lead to direct destruction of electrical components being stressed the most.

Therefore you must have adequate cooling and RAM capable of sustaining the increase demanded from the FSB. PC100 SDRAM = 100MHz, PC133 SDRAM = 133MHz. Therefore, you can "safely" overclock 33MHz on top of 100MHz with PC133 before you must being adding more voltage to the RAM to realize greater and greater increases.

If your system hangs, start over, reset the BIOS using the Clear CMOS jumper and start from the last interval you could boot from.

K6 family processors are always free in their multiplier - you could run them on any bus speed 100 MHz or below, and configure a multiplier that brought them to their intended speed. E.g. a 500 MHz model could be run at 5x100 just as well as 6x83.

The 599 board won't let you do more than 100 MHz bus. This being an integrated-VGA board, you should aim for highest bus speed not highest core clock - e.g. 5.5x100 will perform better than 6.0x95.
