Dropping frames on IDE 133 controller card.

[deliriumaximus]

I have a strange situation. I have my Maxtor 200 GB on my Proise TX2 IDE133 controller card, and it keeps dropping frames in Pinnacle Studio 8 and Adobe primiere 6.5. Apparently the transfer rate for the drive is too slow to capture DV.

So I took the drive off of the controller card & I put it as my primary slave on my IDE 100 port on my ASUS motherboard. Now the transfer is good & I can capture DV without dropping any frames. What gives? I thought the IDE133 controller card would be faster. The Drive is a IDE133 speed, but how come the controller card slows down the HDD?

Help?

it may be slower if you have a bottle neck on your pci buss or problem w/ your pci buss .. put the card in a buss master slot and see if that helps any ..
you may be also sharing a interrupt w/ your audio card and/or network card .. which really can effect performance on some systems ..

what is a bus master slot? Is that the 1st PCI slot? It is already in the 1st slot, the one closest to my AGP card. Could it be a problem with my Nforce chipset, which has integrated sound & video?

All recent motherboards support Bus Mastering in all PCI slots; that only means that a device that requires it, can take control of the bus so that it has preference in the data transfer per cycle over the PCI bus. Check the website for the motherboard manufacturer to see the details of your motherboard. You could also just move the card to another slot; sometimes it solves the problem if there was an IRQ conflict
