Hello, i dammaged my processor but now i dont what type processor i have to buy to replace the old one and i also dont know what socket it is. It is a Packard Bell computer. Thanks for your cooperation. Regards, Ton

Hello here is the cpu list, for the asus board:

http://www.asus.com/Motherboard/P5QLCM/#support_CPU

Here is the msi site:

http://www.msi.com/product/mb/B75MA-P45.html#/?div=Basic

Your current cpu will not fit on the msi board, because it is a different socket.

The asus board has socket LGA 775, and the msi board has socket 1155.

You have to buy a new cpu for the msi board, to make it work.

Here is the cpu list:

If you want to keep the socket 775, you probably have to find a used mainboard, because this socket type is phased out.

Some online stores still have this mainboard type available, but a new mainboard will have the DDR3 ram socket.

Good luck

what u mean compatible? if u mean u want to change your ms 6540 to Asus P5S800-VM, then i tell u it cannot be done.
first thing that u look when to change mainboard is SOCKET type... ms 6540 have socket type 478 and asus p5s800-vm have socket type LGA775. thats mean your old processor cannot be use in asus. socket 478 is older than LGA775.
So if u want to change your mainboard for ASUS P5S800-vm, then u need to change your processor to... about RAM socket and VGA socket, ms 6540 have same type with ASUS P5S800 (DDR400) so u dont need to change your RAM and VGA (if u use external VGA)
hope this useful, regards.

Socket 478 is a very old socket type, it's been around for nearly a decade. The only processors that work with this socket are Intel's Northwood Pentium 4 and Celeron processors, which are now far surpassed in performance. I would definitely recommend buying a new motherboard for whatever you were going to use this one for. If you are set on this motherboard, however, read on.

Many computer hardware companies have stopped carrying Socket 478 processors. You will most likely have to buy one second-hand. A quick search on Amazon will give you a few buying options (all used) for around $20-$30 US.

Due to the age of the processors, you will probably need to purchase a heat sink seperately. This heatsink is $20, will fit Socket 478, and has very good reviews, but of course feel free to use any heatsink as long as it fits Socket 478: http://bit.ly/hk6yZ5

If you also need memory, be sure it is DDR 333/266, as this is the ONLY type of memory that the 2 memory slots on motherboard will take (maximum 2GB of memory). You can find list of DDR 333 memory in varying capacities here: http://amzn.to/fOGbeV

pentium 4 2ghz socket 478, either a northwood or prescott type of processor, visit this link for your reference when buying a processor for your motherboard,

well...ASUS P4S533MX- Intel socket 478 allow maximum processor upgrade from 3.2 GHz upto to 4.2 GHz.
for upgrade the Radeon 9250, 128 Mb DDR 64-bit ....whole moherboard along with new processor has to be replaced. an expensive deal..
better to buy new motherboard+compatible processor of ur choicce

Use the free tool on this site to scan your PC to determine what kind of memory you need:

okay as long as the heatsink fits it will work. socket type is for the processor. also dont forget the thermal paste. look up www.ribbitcomputers.com

Compatible Processors
Sempron, Athlon 64, Athlon 64 FX, Athlon 64 X2
64-bit Processor Compatibility
Yes
Mainboard processor socket
Socket 939
Mainboard / Multi-Core Support
Dual-Core
Chipset Type
VIA K8M890 / VIA VT8251

As your processor is very old, to buy an upgrade would be more expensive than buying a new computer. There are not many of the socket 370 type processors around, if at all. Your motherboard will not drive any of the newer processors.
Sorry

A7 indicates that it is a K7 series - a socket 462. Socket 7's were for the old Pentium 1's and AMD K5, and K6 I,II, and III series of pre-athalon processors. Socket 7 was also the last socket to see Cyrix chips.
