It is so crazy for a 486 board.

I seem to recall a site in not entirely sure whether it was fake or legit about 100 years ago
Temple of the llama or something like that.
Anyway, with a modified fridge, filled with vodka they got a 486 over 200mhz Iirc.
It's an ancient memory and I recall it seeming legit enough at the time.

How did you manage to get the POD to run at a 1.5x multiplier? I thought you could either use the default of 2.5x or block the fan sense pad for 1x??

I don't know, I just plug the CPU in and it post at 100MHz, with 66.66MHz FSB.

I will install a permedia 2 PCI to run quake to verify that is true or not.

Permedia 2 installed

P24T running @100MHz is true??????

Could be one of those oem specials.

Someone big like Dell, IBM or HP usually have the ability to get things that otherwise don't exist.

There were a couple of 64-bit 478 p4s, and the 2878 v3 xeon with Ddr3 support exists

Maybe, but I don't know why?

a bit of calm look.....
1. this is not the LS 486 motherboard!!! but BEK-tronic
BEK-P407.
2. jp5 settings are for 40Mhz ... 2.5x40 = 100...

Yes and too bad the SpeedSys cache chart had been interrupted.

Wired.......

The jumper location and position are the same as Luckystar LS-486e.

The score of quake bench of the "100MHz" on this board also lower than POD83@83MHz ,FSB@33MHz on M915i(no L2 cache) board. Wired.......

Maybe just maybe the SiS chipset performance is very sluggish.....

Are there better tool to verify the FSB @40MHz instead of 66.66MHz?

Look at the clock gen, and read the chipsets datasheet.

That makes no difference in the result. I cannot see the write and move chart.
Did you know you can save the SpeedSys result into a .pcx file?
That pcx file easily can be converted to a .png file and uploaded here 😀

How to save to .pcx file? any parameters?

I'll try later.
