Question about Shuttle AV49VN Motherboard

Upgraded cpu- wont boot

I recently upgraded my shuttle av49vn motherboard from a 2.6ghz 400fsb celeron to a 2.8ghz pentium 4 with 533fsb. There is a jumper on board to change fsb speed to 533 and completed same. However the board wont boot with the new processor. Could the memory i have installed or the bios have anything to do with this? Considering the board is made for a p4 processor, i cant imagine it came with a bios not compatible.

Teresa, if you changed the front side bus to 533, your memory must have the same clock speed. Memory clock speeds are what is known as "backwards compatible" but not forwards. This means that you could put a piece of memory of a clock speed of 400mhz into a system that runs at 333mhz and it will "downclock" the memory, but you could not put a piece of 333mhz memory in a 400mhz fsb pc and expect it to run. one of two things will happen, the system will not boot at all or the syetm will downclock the processor to a slower speed. In your case your cpu must be 533mhz clock speed with pc4200/533mhz memory to function correctly.

Hi,
You should get one bios beep. You seemed to have tried everything except a different hard drive. Check the capacitors to see if they busted open. Other than that the motherboard could be fried. Hank

REPLACE FAULTY CPU CELERON 3.06GHZ WITH PENTIUM 4 CPU


Your motherboard specs are at http://www.foxconnchannel.com/product/Motherboards/detail_spec.aspx?ID=en-us0000152

Looks like you could go up to a 3.8GHz P4, make sure you get a fan that will cool it properly.

Cpu upgrade wont happen


Ok i checked the ASUS website and looked up the CPU compatibility list for your board here:
http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us

But unfortunately that particular CPU doesn’t seem to be supported. Must be something to do with the technology inside the CPU or the amount of L2 cache or something like that. (it would require some rather intensive research to find out exact reason why...

And when searching for ASUS motherboards that are compatible with that CPU it comes up with this short list;

AP120-E1
AP130-E1

PSCHL009
AP140R-E1
P4RD1-MX


Did you clear the cmos when installing the new cpu before powering it up?

i know the CPU you have now runs at 400FSB and the new one runs at 800FSB But that board supports both speeds so that shouldn’t be a problem.

What type of RAM do you have ?
maybe check owners manual for memory compatibility chart for new 800FSB CPU

Have you tried the latest beta bios from ASUS site :
I can not guarantee that it will work but it is worth a try.
http://support.asus.com/download/download.aspx?model=P4S800D-X%20&f_type=34&SLanguage=en-us
NOTE: Updating the bios can be risky and should only be done to resolve compatibility issues or things like that (or to add CPU support) In the rare event of a power failure during bios update your motherboard could become permanently unusable. (Always use a brand new floppy and follow the instructions to the letter when updating system bios)

are you sure that you have the same zif socket types either a intel celeron or an intel pentium, they are different socket types, but if theres nothing wrong with your other cpu your not going to see any difference in speed, upgrade your memory, but obviously if your other cpu has failed check the socket types and then reset your bios on the motherboard shorting terminals.
