Need Help on install of a Celeron 400

[Ranger361]

I'm want to install a Celeron 400 on a BX6 (1.05) MoBo and can't find the setup spec's for the processor, voltage, HHz and clock speed settings. Right now the Soft Menu shows the chip as a 400 MHz and the default voltage is set at 2.0 The computer seems to be running pretty slooow . . .

Any help or suggestions would really be appreciated??

Hmm I dont see what you can do about the celeron being slow.

2.0 is the correct voltage. Overclock it. Very unlikely it will run at 600 Mhz (100Mhz FSB), maybe you'll get lucky. 450Mhz (6X75) ought to be a gut cinch.

I got my old PPGA Celeron 400 up to 600@2.0v , but would get lock ups playing Q3 upping the voltage didn't help:frown:

Thanks for your help . . . I tried the overclock (6X75), but at the end of the POST I receive an error message that the CPU has changed. Going back into the bois the CPU had defaulted to 266 Mhz. As you can tell I'm a newbie and not really sure what I'm doing.

In the Soft Menu how should I set "SEL100/66#" Low or High and
AGPCLK/CPUCLK, currently it is set at 1/1 ? I tried setting the External Clock to 75 and the Multiplier to X6, then went to Save Setting and Exited. During the POST it showed up as a 450 CPU and at the end of the POST I get the error.

Many times, the hard drive may be the bottle neck. THis is especially true of old 5400rpm hard drives. a Celeron 400 should be pretty fast if you have enough ram and a 7200rpm hard drive. My lab has a overclocked 800mhz celeron machine but it's slow because it has a old 4.3 GB HD.

Your Softmenu should be set like this:

CPU Operating Speed : User Define

- External Clock : 75 MHz
- Multiplier Factor : x6.0
- SEL100/66# Signal : High
- AGPCLK/CPUCLK : 1/1
- Speed Error Hold : Disabled

You probably had speed error hold enabled, thats why it came up with the 'CPU has changed' message.

The SEL100/66# setting doesn't really matter. Its only useful if you have a PII 350 or 400 and want to overclock.
