VX-97 Mobo Query

[KPVince]

I have upgraded an SP97 up to a K6 2 450 running with an FSB of 83. And it's stable like a rock. You can look for the Jumpersettings at the Asus homepage, FSB 83 Mhz is undocumented, I could run the Ram asynchronous. You only need a big cooler, because the Mobo will be very warm. I don't no if it works with an VX-97, but there are some information on the Asus homepage, I think it would only work with a K6-2, and I think the multipler of 2 interprets he as 6.

Hi there.

I want to upgrade my Asus vx-97 P-75 to a k6-2/3 400mhz.

From the info I've been able to scrounge up it would appear that the mobo supports the required voltage(not exact but within a few millivolts),bus freq (66/75), and the multiplier of 6.

I am only concerned about the amperage. Does this mobo support the amperage needed by the k6-2/3 series ? The Asus pentium mobos I've seen support 12 amps, but any technical info for this mobo is *difficult* to find.

Has anybody upgraded this mobo before ?

Any help will be greatly appreciated.

Thank you

The SP97 indeed is different - its SiS 5598 chipset is designed for 75 MHz (later steppings even 83, but I'm not sure if ASUS came to use these), and can run 75 and 83 MHz while keeping PCI at 33.

Intel's VX can't do any of that, so it's limited to 66 MHz for correct system operation.

Thanks for the information.

Peter does this mean that the k6-2/3 series will not work at all on this motherboard at all ?

I was hoping that it would work even if it was a bit slower than normal.

No, this means you're limited to 66 MHz bus unless you use a Cyrix processor.

Using their 6.0x multiplier, this takes you up to 400 MHz with AMD processors. Best fit would be a 400 MHz 2.2V K6-III. Don't use the 2.4V ones, they draw too much power.
