Pentium II 350 only runs a 290 in my ASUS P3-BF

[jpej]

Hi people!

I have a PII 333 that runs a 415M in my ASUS P3B-F, last night i exchanged this 333 processor by a PII 350 (i get this in a machine at my work), but this 350 processor doesn't run at 350 (!!)
In the original machine it runs fine at 350, but there in my machine it runs only a 290!!
If I put it at 350M, my windows(ME) boots, but freeze in the login screen, or when I just open a menu or something...

I think that it's a configuration problem or something... please, help me!

My Machine:

PII 350@290 (durh)
Voodoo3 3000
MB ASUS P3B-F (BIOS updated)
Sound Blaster PCI 128
Modem Blaster DI 56000
2 HD (Samsung 4 GB, Quantum Fireball 8GB)
CD ROM - Creative Infra5400

did you reseat the processor? make sure there is adequate cooling?

I don't know the P3B-F but you seem to have multiplier/fsb problem...

333 = 66 * 5 right?
415 = 83 * 5 ....

350 = 100 * 3.5 ....
290 = 83 * 3.5 ....

So at 290 you are running you 100mhz processor at 83 mhz....
but the problem is how do you set your processor to run at 350??
if you are using the same pci and agp settings that you use for the 83 fsb, that might be the problem especcially if you are using a 1/1 agp setting.... a voodoo3 running at 100mhz agp isn't
going far....see you pci and agp setting and set them to 1/3 and 2/3 for 100mhz fsb....

Hope it helps....

Great

I wanna call you Master

The ASUS P3B-F has a dip switch to set the AGP multiplier, 1x or 2/3x, my setting was 1x (the bus for a 333 MHz is 66, so, no problem).
I set it to 2/3x and everything is going well.

In the setup I can choose the CPU Bus/PCI Freq., for 350 MHz the setting is 100.3/33.43, I'm now running the processor at 466 MHZ (it's freq multiplier is locked in 3.5)

What's your sugestion to overclock it?

Glad you are doing ok....

I think that 466 is the most you will get from that PII-350...you at 133 and 2/3 the agp is at
89mhz...way off spec...but if you have been running it at 83 you should be ok

Now you pci...watch out for your pci devices and hard-disks.....I don't know if the P3B-F
has a 1/4 pci setting in it, if it does use it...if not test your system at 466 for a while
and check for strange crashes and data corruption... if none occours, there you have it a
350@466...

BUT if you start getting errors and crashes step back a few mhz...its always better safe
then sorry...

Have Fun....

I also o/ced my p2 350 to 466, but.....
Somehow the l2 cache died and now the computer thinks it a celeron
