I know nothing about this area of computing, and I need to know what some switches on my motherboard do. I'm referring to 6 tiny switches located near the CPU and ram that can be flipped to the on or off positions. Instructions for their use are printed on the motherboard.

Switches 5 and 6 clear CMOS and Password data if turned on, and switches 1-4 can be arranged in 4 patterns that correspond to 4 listed CPU speeds: 233, 266, 300, and 333 MHZ.

What I need to know is, are switches 1-4 for setting the speed at which the processor runs (ie, set the pattern for 233 MHZ to make the processor go 233 MHZ) or are they to tell the motherboard what speed the processor is designed for (ie, if the processor is supposed to be a 266 MHZ processor, you set the pattern for 266 MHZ).

Thanks.

The first one is not 233. It's 133. Now I really goto go.

Are you sure? As I said, instructions as to the operation of the switches are printed on the motherboard, so it would have to be a misprint for it to be 133 and not 233.

Just noticed it was old. 233 is correct. Sorry.

It would help if you posted the make/model of your board. Usually, a DIP switch is used for the FSB, multiplier, or CPU voltage...or a combination. That's the 1st I've heard of one used to ClearCMOS as well.

The switch settings determine the speed the CPU is to be run at. If you have a 233mhz CPU, configure the switches to the 233 settings. If you wanna try overclocking your 233, change the settings to 266 & see if it'll boot & run

unless of course, the multiplier is locked...

I'm sure if you study the different switch combinations for the different speeds, you'll be able to figure what switch does what

I wish I knew the motherboard's make/model. I got it from an HP Vectra VE 7 computer, and the only make/model-esque markings on it read "VL-609".

Anyway, when I got the board, the switches were set to 300 MHZ. I just set them to 333 MHZ and the computer boots up and runs without crashing, but it doesn't seem at all faster. Additionally, it still lists "Celeron - 300 MHZ" on bootup. Is this normal?

The multiplier on the Celeron is locked. The 300 runs at 4.5 x 66...the 333 runs at 5 x 66. The switch that you're changing is apparently for the multiplier, & unfortunately, the locked CPU will override the switch setting & stay at 4.5x.

The only way to increase the speed of your CPU would be to raise the FSB & I'm guessing that your board only supports 66mhz FSB
