I am not sure what processor I can upgrade this older motherboard with. Right now I have Processor Model : AMD Athlon(tm) Processor Speed : 850MHz Model Number : 850 (estimated) Cores per Processor : 1 Unit(s) Threads per Core : 1 Unit(s) Internal Data Cache : 64kB, Synchronous, Write-Back, 2-way set, 64 byte line size L2 On-board Cache : 256kB, ECC, Synchronous, Write-Back, 16-way set, 64 byte line size other specs: System Bus(es) : ISA AGP PCI USB i2c/SMBus Multi-Processor (MP) Support : No Multi-Processor Advanced PIC (APIC) : No System BIOS : PTLTD - 6040000 Total Memory : 512MB SDRAM Chipset 1 Model : ASUSTeK Computer Inc VT8363/5 KT133/KM133 System Controller Front Side Bus Speed : 2x 100MHz (200MHz data rate) Total Memory : 512MB SDRAM Memory Bus Speed : 1x 133MHz (133MHz data rate) Video System Monitor/Panel : LE500 Adapter : RADEON 9800 Adapter : RADEON 9800 - Secondary Physical Storage Devices MAXTOR STM3320620A (ATA) : 298GB (C:) I just want something a little faster than 850MHz. If I can even upgrade? Any help is very much appreciated! BIOSTAR G965 Micro 775 Pentium 4 3.6GHz Crucial Ballistix 2GB 800 Geforce 8600 GT

The ability to upgrade your CPU depends on it's form factor. The first generation of Athlon processors used a slot A form, similar to Pentium II and III. If you have one of these CPU's then your upgrade options are somewhat limited. If you have a socket 462 then you have some room to upgrade. Download the manual for your motherboard from the ASUS web site and it will tell you how high a CPU you can upgrade to.

I am not having any luck on ASUS website finding a manual. What model number would it be? Is it listed in the specs I posted above? BIOSTAR G965 Micro 775 Pentium 4 3.6GHz Crucial Ballistix 2GB 800 Geforce 8600 GT

The HP Pavillion will use an ASUS OEM board, specially made for HP, therefore you should be perusing HP support for details of your PC. http://h10025.www1.hp.com/ewfrf/wc/...

You can go up to a 1.2 ghz more than likely,thats the ends of that processor family. You might be able to go higher but doubtful your board will support it.

Thank you for your response. I think I would be better off going with a newer mobo & pros. but I thought i check. Thanks BIOSTAR G965 Micro 775 Pentium 4 3.6GHz Crucial Ballistix 2GB 800 Geforce 8600 GT
