Ratio = Multiplier?

[Zim2411]

I'm at a friends house and we a trying to revive a dead mobo.

Anyway, we are trying to find out what the heck the Ratio is.

It says switch 1-3 is the ratio. Do they mean the multiplier?

Also its a Lucky Star 5MVP3 Rev 4.0. We are trying to get a 400mhz K6-2 to work. Also, i cant figure out if the K6-2 needs 2.2 volts or 3.3 volts to work.

It says 2.2v Core/3.3v I/O on the chip

Ratio is the Ratio of the FSB:MEM FREQ
and Mulitplier is we'll the mulitplier ;d

Umm... what? the FSB is set to 100mhz, and the ram is PC100. I'm offered several choices with the ratio. 1.5x/3.5x, 2x,2.5x, 3x, 4x, 4.5x, 5x.

Which should i set it to?

A K6-2 will use the 2.2V core. Only the earlier K5 and some plain K6's used the higher voltages.

I have no idea who actually made the "Lucky Star" board, but can comment on my own system based on the same chipset (FIC VA503+ based on VIA MVP3). My board has two sets of three trios of jumper pins (you could have two sets of three dip switches instead). My board has multiplier settings identified as "CPU to Bus Frequency Ratio" ranging from 2x to 5.5x. The other set of three switches is for your front side bus frequency which range from 66MHz to 124MHz on my system.

I believe that the setting for the K6-2 400 is 4x100. Finding that setting on your board may take some "trial and success" effort without documentation.

Set the voltage for 2.2v, or as close to there as possible depending on the options available on your board. And if you're in need of a BIOS update the one listed here (http://web.inter.nl.net/hcc/J.Steunebrink/k6plus.htm) is probably the most advanced. The BIOSii listed there are to enable Super Socket7 boards to use the K6 "plus" chips, the last and most advanced of the Super7 line and a lot have other advancements like removing the 32gig hard drive barrier. Also keep in mind K6-2 chips re-map the X2 multiple to X6, so if your cooling is good enough and the chip is a really good (phenominal) oc-er you could get up to as much as 600mhz (100X2). This (http://www.georgebreese.com/net/software/) site has a utility to enable 4-way memory interleaving on older VIA chipsets like the MVP3. Scroll down the page about halfway and you'll see it. My MSI motherboard with MVP3 chipset had the interleave technology didn't have it enabled nor a way to enable it in BIOS, when I used that utility my memory scores jumped by just under 20% (tested in SANDRA). Hope it helps. :)
