Tip 2 Set DMA for all drives in system
Make sure DMA is set on all drives (hard drives, DVD-ROM, DVD burners, CD-ROM). If it’s set to PIO, it’ll use almost all your CPU to transfer data and is a common complaint as to why it’s taking forever or people exerperiencing buffer underruns while attempting to burn DVDs.
Double click on Primary IDE Channel and also Secondary IDE Channel
Verify all Devices 0,1,2,3 are all set to DMA. Notice for Device 1 there isn’t any device so it’s it’s N/A.
Be sure to reboot for the DMA mode to take effect.
Tip 3 CPU Burn-in (CPU tester)
Download CPU Burn-in CPU_burn-in.zip Many people overclock their CPUs and they never have problems until they try to encoding with CCE, or transcoding for an hour. Either the CPU will overheat and cause the computer to shutdown completely or other erratic behavior.
Try running CPU Burn-in for about 20 minutes or more if time permits. It’ll stress test your CPU and system and determine if it’s stable to handle processor intensive applications such as DVD backup encoding, etc.
Open task manager (right-click on taskbar) if you wish and you’ll see the CPU at 100% constantly for the duration of the CPU Burn-in test.
CPU Burn-in ran and had no errors to report so the CPU doesn’t overheat under heavy load.
