It's me again. I had a motherboard laying around that I thought was broken because it wouldn't boot properly, but after I found out my Celeron 300A was multiplier locked and how to change the motherboard settings, I've set it up so it runs fine. I want to increase the FSB and take my Celeron from 300 MHZ to 450 MHZ, but I can't seem to figure out how this would be done. I know the motherboard supports the necessary FSB increase (I think it's from 66 to 100 MHZ, isn't it?) because the multiplier select setting that is labeled to support 300 MHZ is also labeled to support 450 MHZ. The problem is, the motherboard is some sort of weird, OEM-custom model. It's a FIC VB-609, found in HP Vectra VE Series 8 computers. It's has no apparent methods of changing the FSB, is not supported by FIC (at least, it doesn't look like it) and the latest updates by HP do not present a method of changing the FSB. Is there some technical way to do this, since the motherboard should support the FSB change, or has HP locked it up for good?

Are there jumpers or a DIP switch on the board?

Is this your board? http://www.fic.com.tw/product/motherboard/1stmainboard_detail.aspx?type=legacy&model_id=69

It's got the same bank of 6 switches as the VL-609 mobo from my last topic, which can be used to set the multiplier. There's none for the FSB. The motherboard has no jumpers as well. Another question: can you "modify" a processor to unlock the multiplier? I read something awhile back about taking out a part or two and it would be unlocked.

Missed that post, sorry. That board is completely different from mine.

That's not the picture that goes with the description...are the specs right? Number of slots? AGP, 5 PCI, 2 ISA, 3 DIMMs? Not sure if this option will be available for you, but look for a setting in the BIOS called CPU Host/PCI Clock...it will be under "Chipset Features Setup". It's probably be set to 'default' now...try changing it to 75/37, save your setting & reboot. If it works, your CPU will then be running at 337.5mhz. If you wanna go for broke, try 100/33...if it won't boot at that setting, you'll have to clear CMOS & start from scratch....

Slot numbers are right, but other specs are incorrect. The board doesn't support P3 processors (it will physically, but will not identify them and operate properly), and I believe it only supports 128 MB of RAM per slot, the specs say 256. Additionally, things in the onboard I/O specs are wrong, such as the USB ports and audio. And the BIOS doesn't even have a chipset settings area. It's the most pitiful BIOS ever. I assume my only hope is to find a motherboard with identical specifications to mine and try the latest BIOS update for it to see if the necessary option becomes available. Will that work?
