Hi, i dont really know too much about the internals of pc. i just formated my pc and installed win 7 (from xp), i want to upgrade the ram also because i only have 1 gb.... but what is the maximun memory my motherboard can handle?? i use SIW (system information for windows) and it told me this: Motherboard: Property Value Manufacturer MICRO-STAR INTERNATIONAL CO., LTD Model MS-7312 Version 1.00 Serial Number North Bridge VIA K8M400 (VT8380) Revision 00 South Bridge VIA VT8237 Revision 00 CPU AMD Athlon? 64 X2 Dual Core Processor 3600+ Cpu Socket Socket AM2 (940) System Slots 4 PCI, 1 AGP Memory Summary Maximum Capacity 8192 MBytes Maximum Memory Module Size 4096 MBytes Memory Slots 2 Error Correction None Warning!

Every site also tell the north bridge is a VIA k8m800 and that the motherboard has only 3 PCI slots........ but SIW tells another thing... I hope you can help me Official Homepage of my specific motherboard Other site with specs Thanks a lot!
