Can you help to overclock my PII 350 ?

[Robert - Jan Lankhorst]

I have an Aopen AXBC mainboard and a PII 350. Aopen's site says it possible to set busspeed at 112Mhz to reach 392Mhz. They almost advise it. But each and every time I want to boot, the systems hangs at the moment Windows 98 is creating the desktop items. I do have good quality 64 MB SDRAM PC100. Do you have any suggestions.....?

Some device in your comp can't handle the 37mhz PCI bus frequency, probably the hard drive (maxtor?) Set the PIO mode in BIOS to 2 or 3 instead of 4. Either that, or heat is causing the problem. Leave the case off the computer while you boot up, or get a bigger fan/heatsink if possible. Also get some thermal grease\compound.

Might be more stuff that I can't think of at the moment.

I have the same problem...I can hit 102.5 bus (100 w/ turbo)
but i cant hit 112
I just found out a few days ago from a program that I was sold PC66 ram capable of 100, not true pc100.
Im going to get a new 128 stick of true PC100 and sell my stick of 66 to a celeron user. I think then Ill be able to get to 392 at least.
So..its the ram for me...might be for you too

how did you guys change the bus speed or multiplier and would you need any additional cooling from the 350 to 392 jump.

[bigslammer]

auraedge what program did you use to determine the speed of your ram.

I got the link from this board...not sure were tho but sometime this week or last week
I can send u the program if u want, but lotsa people say theyve been having trouble running it
I have no trouble, however
Multiplier cant be changed on newer processors....
Bus speed is either changed on the motherboard's jumpers, or if its 'jumperless' in the BIOS. You press delete at the computer starts up to access it...beware tho...Lotsa very technical terms in there...and BIOS is the one place where u dont wanna screw up your comp.
I dont need any extra cooling to hit 361..but thats only an 11 Mhz jump
the only extra cooling in my case, is a fan in a PCI slot to cool down my AGP card (i got that overclocked) and an extra case fan
I keep my stuff runing a 350, because 11mhz extra aint all that. Its not worth not running it at spec

The PII 350 was not one of Intels Better overclockers, your motherboard does not allow you to raise the core voltage, which is probably the only way you will get this chip to hit 392, there is a way to raise the core voltage by taping the pins on the PII circuit board, but I have never done this and don't know which pins to tape

I have a PII 350 and have been running at 392 for months now. I even ran it at 133 for a bit, only it frose when the memory manager started checking, so probably a memory limitation. It's just luck, basically, although good components and cooling do help somewhat.
