Mother Board Settings

  stumps 14:23 19 Mar 03

have rently upgraded my CPU from 1000Ghz to a Athlon Thunderbird 1.33 Ghz 266 Side bus.
I changed the dip switches on the M/B to the configuration from the manual. The machine worked 1st time but I just get the feeling that the machine is not quiet as speedy as with the 1000Ghz Chip in place. Have I missed something in the set up or are there BIOS changes to be made as well?

The M/B is a Soltek 75 KAV Power supply is rated to Athlon requirements.

Anyone help?

You need to go into bios and tell it the CPU speed is 133

NOT 266(it's not an option) or 166

133 is doubled to give 266 fsb
166 gives 333 fsb.

You then need to check the multiplier, which should be 10 I think.

133 x 10 = 1330 or 1.33Ghz

If your speed is still set to 100 (default) you'll have the PC running at 100 x 10 = 1000 or 1Ghz.

I made this mistake and my PC was running at 100 x 15 = 1.5 Ghz instead of 133 x 15 = 1995 or 2Ghz

Change CPU frequency to 133 in BIOS. There are several RAM options, see below.
