I've built an HTPC and I'm having problems with MCE. TV recordings often end up jumping and skipping and are completely unwatchable. Machine specs: Gigabyte GA-81945P Motherboard Intel Pentium 4 3.2GHz CPU 1GB (2 x 512MB) Crucial RAM Asus 7600GT 256MB GPU 200GB Seagate Barracuda SATA HDD EDIT - 2 x Hauppauge WinTV-Nova-t PCI tuners What is the minimum RAM/HDD space required for trouble free MCE operation? The Giga-Byte mobo will support 4GB RAM so would an extra pair of 1GB DIMMs help the situation? Any suggestion will be hugely appreciated..... EDIT - Current RAM specs: DDR2 PC2-5300 • CL=5 • UNBUFFERED • NON-ECC • DDR2-667 • 1.8V • 64Meg x 64 - Should additional RAM be 5300 or can I use 6400?
