Locate the K34063A IC.



CLK
Clock input. Provides fundamental timing for the processor.

BF0-2
Bus Frequency clock multiplier (bus to core frequency ratio).
1.5x and 2.0x when only BF0 is present.
1.5x, 2.0x, 2.5x, and 3.0x when BF0 and BF1 are present.
2.0x, 2.5x, 3.0x, 3.5x, 4.0x, 4.5x, 5.0x, and 5.5x when BF0, BF1, and BF2 are present.
[ Note: What multipliers are available is entirely dependent on the processor itself. ]

Using AMD K6 350MHz, I can choose following FSB settings:
60MHz
66MHz
83MHz
75MHz
100MHz

Multipliers:
2
2.5
3
3.5
4
4.5
5
5.5

Unfortunately there is a glitch in the BIOS, when using the 100MHz FSB setting I noticed how the multipliers settings did not match with what is applied in real life. Using multi 5 whould set the multiplier to 4.5 in real life. This happens only when using the 100MHz FSB settings, for the whole range of available multi's. Downside is that the highest I can set my CPU at is 500MHz (100x5.5), which is just barely higher then 85x5.5 (470MHz CPU).
Record is at 550MHz for now, I know I can easily hit that speed if the mainboard would not have the glitch.

I noticed how the ASUS P5A allows up to 120MHz FSB, this would bring me at 600MHz. Might require phase change cooling though.

I really need own PLL for CPU.

Excellent, I have the same motherboard lying around, I have the Asus P5A as well and have another board coming to me from germany.

Revival of the K6!!

What, no valid entry? Others do it too, no penalty for them?

Pentium 1 166MHz MMX Test



Stock: 66MHz FSB x 2,5 multiplier = 166MHz

Test results:
100MHz FSB x 2x multiplier = boot, nice: CPU will like the bandwidth
100Mhz x 2,5 = boot
100Mhz x 3 = boot
100Mhz x 4 = boot
100Mhz x 5 = boot
100Mhz x 5,5 = boot ....... wait a minute, is that even possible????


For the 100MHz x 5,5 (550MHz) I had to increase CPU voltage up to 3,4V, but considering it is aircooled I began to question if that was even possible. That's more then triple its original speed... So, I let it boot into windows, there I noticed that the CPU speed is at only 314MHz (windows system readout).

In real life I don't think that the clock speed shown at system boot is not correct, to far beyond specs and others seem to hit only around 300MHz using same type of cooling. Hwbot scores: http://www.hwbot.org/quickSearch.do?...66Mhz+%2874%29

Still good enough for me to get the gold medals, only have to get the USB interface working so that I can start installing software. I only wonder where all these verifications files went to, almost no entry has a picture included


Anyway, I think this is a very good example why you should not accept system boot screenshots

promising bootup OC, indeed unbelievable clocks on air; too bad it didn't last until windows

CPU-Z ranking is CPU-Z ranking

what do you mean with
