Hi All,
I had a box centos5 AMD64 X2 4200+, Asus motherboard, Nvidia 7100 video card, 512M, when playing a video at 1080p it did well but had a couple times went out of sync.
So amd dropped its price and I got a 5200+, gigabyte motherboard, Nvidia 7100 video card, 512M. This FASTER system is actually slower. The video is WAY behind on sync.
I have looked at the X config they are the same. I have the same mplayer version I have the same centos 5 version The CPU usage is actuall below 60. I ran "cpuspeed -C &" on both boxes
/proc/cpuinfo on both boxes report the correct values. 4200+, 512cache, clocked at 2200 5200+ 1024 cache, clocked at 2600
What can be causing the faster machine to SUCK so bad at playing the video back? THanks,
Jerry
It could be the interaction between processor, memory, bios (motherboard), chipset, and a host of other things. The best test would be only changing ONE component at a time. Are both chips socket AM2? If so, try the 5200+ in the Asus board, or the 4200+ in the Gigabyte board.
Are both boards using a pair of ram sticks in the proper slots to get memory interleaving properly?
There are so many variables to look at.
