Hi All.

I've got a TI7NBFV on the way, which uses the Apollo Pro+ chipsets.
All indications, such as on https://theretroweb.com/motherboards/s/tmc-my … egastar-ti7nbfv, indicate that it has a maximum of a 100mhz FSB and only supports up to Coppermine Socket 370 Pentium III CPUs.

However, going into the manual: https://theretroweb.com/motherboard/manual/ti … 05600893968.pdf
It shows, unless I'm reading this wrong, the ability to function at bus speeds up to 150mhz.

I then looked at the voltages, with my understanding being that the Tualatin P3's requires 1.475v whereas the Coppermines are usually on 1.75v.

The board again shows in the manual that it has a CPU switching voltage of between 1.3v to 2.0v (or higher when a jumper is opened).

So, despite all the indications to the contrary, do you think this board would support a Tualatin CPU? I don't have a spare one to test, and I'd rather not purchase one only to find that it doesn't work, though I do understand that with this sort of tech archeology, there is always an element of risk.

Does anyone have one of these boards to confirm/deny?

If the chipset is really the VIA VT82C693 as listed on TRW, you will only get 100 MHz FSB support.
However, when I Google the name of the board, I get Chinese websites that reference the 693A chipset. That one supports 133 MHz FSB.

In any case, Tualatin will NOT work.

I know the chipset is only rated for those speeds, the manual would seem to indicate that it can be set all the way up to 150mhz bus speed.
4.1 CPU Frequency/Speed Setting The motherboard allows users to set the CPU speed through the BIOS. The parameters in setting the CPU speed include CPU Clock Multiplier (X3, X3.5, X4, X4.5, X5, X5.5, X6.5, X7, X7.5, X8) and CPU/PCI Clock Select (66/33MHz, 75/37MHz, 83/41MHz or 100/33MHz, 103/34MHz, 105/35MHz, 110/36MHz, 112/37MHz, 115/38MHz, 120/40MHz, 124/41MHz, 124/31MHz, 133/44MHz, 133/33MHz, 140/35MHz, 150/37MHz). The parameters only appear when CPU Speed is set to Manual.

To be honest it's hard to say as description say it's slot 1 motherboard . However manual states it's socket 370 . I assume that manual has been created for the few models.
