kotori - Athlon 700Mhz (Slot, Argon) @ 911MHz - 2min 58sec 400ms PiFast

What signals was necessary?


Sorry, I don't know meaning of the question, where? which?


So you soldered the output of DDS2 to the reference-clock-oscillator and it caused rising of PLL maximum frequency?


Yes, For example http://hwbot.org/submission/3010261_kotori_cpu_frequency_pentium_3_celeron_mobile_500mhz_766.42_mhz

PLL of this board ICS9248AF-61 maximum 100mhz

By the way K7pro fsb is max 119mhz without mod


Or could you explain what signals go where


From DDS2 output to Mother board PLL(X1)

I did not know anything about number of outputs of this DDS2 device. My question was about number of needed signals to make motherboard workable, stable and overclockable. Signals I meant are for example: pci, memclk, fsb and maybe some others. Now as I can see only output sine wave is needed to "cheat" the pll chip.


So REF0 and REF1 pins have to be connected to 14.3 MHz clock source? The second thing is to remove crystal from X1 and X2 and to connect the output sine wave to X1 pin? That's all? :)


Are'nt there any "weird" motherboard behaviour? For example: speed-up time (for example 1minute on modded motherboard is 40 seconds real), not working USB or not working peripherials?


Good work man! I'm very interested and I was thinking about to do myself similar mod but I didn't know anything about which signals-to-be-modded. (and I did not spend more than few hours doing research on "pll-mod" )
