Hey Matt,

I’m running a 1080p timeline at 1/2 Good… still no realtime.

Something doesn’t quite make sense to me. If you have a Mac Pro 2,1 and are running your GTX285 as a 16X, and your GT120 as an 8x, that means that your 2 remaining slots are automatically 1x.

But my BlackMagic Card requires me to run it in a 4X slot, so I have to set my GT120 at 4x in order to accommodate that.

What other PCIe cards do you have in your system and in what slots?

You mentioned eSata, I’m assuming you’re running an ESata card like a Tempo or something…

Anyway, can’t figure out how you can run your GT120 at 8x and still be able to play out video through a BlackMagic Card..

Cheers!

Hey Matt,

I just bought the cards, and have the exact same hardware config as you. But am not able to get anywhere close to realtime playback from 4K files in 1/2 Good. What other cards do you have running on your system?

I have a BM Extreme 2, and a HighPoint RAID.

The problem I am having I think is that the BM Card requires 4 Lanes, and so does the GT120. So I am left having to put my RAID card in the X1 Slot, which is getting me READ/WRITE speeds of 150MB/s instead of the 450MB/s I used to get in my 4X slot.

But short of an expansion chasis, I’m not sure what to do to increase my drive speed.

How fast are your drives running?

Thanks!
