A1640n Hp

[Mitch]

I have a HP a1640N , with a daul Core 6300 , and was just wondering how to overclock it

HPs in general don't have overclocking available to them in bios, and my few attempts at using software on them for OCing haven't been pretty.

Another thing to keep in mind is that while the motherboard may be branded as a known make/model do not!!!! under any circumstance attempt to flash the bios with anything other than something supplied directly from HP themselves. Chances are that it's a proprietary HP bios which is not compatible with the mobo manufacturer's specs and you'd end up not only with a door stop instead of a motherboard, you'd also have lost your OS license as they are tied directly to the hardware and cannot be transfered over.

Also, they're usually low-quality motherboards and memory, so I wouldn't even advise overclocking them if you could (which you can't).

HP generally uses custom-made motherboards by Asus w/ a custom BIOS which contains a "tattoo" for hardware activation. As wilson said, if you flash the BIOS (which you generally can't as they're usually not consumer-available mobos), you will most likely lose your OS as well as your warranty.

I use have a HP a420n with an AMD Athlon XP 3000+ Barton and the motherboard in there was a Asus A7V8X-LA which is pretty much the exact same as the Asus A7V8X-MX . The only difference is the A7V8X-MX did not have SATA controllers. Because Asus made the A7V8X-LA for HP/Compaq if you went into the BIOS you were not given any control over raising the FSB, Voltage or Memory timings. And yes if you try to Flash the BIOS say with the BIOS for the consumer version of your motherboard and you are successful (highly unlikely) you will most likely lose your warrant and could damage the board.
