Maximum number of Hauppauge HVR 1600’s on PCI bus

How many Hauppauge HVR 1600’s can I put on the PCI bus before overwhelming the bus for multi-channel recording?

I have a quad core 3.0 GHz Phenom II system with 8GB of DDR2 ram (AMD 740G / SB700). It is running windows 7 professional 64-bit. I am using tuner salad to get past the 4 tuner per type limit. I have 3 xbox 360’s I use as extenders.

For a long time I had 2 Hauppauge HVR 1600’s recording 2 ATSC signals (and a HDHR to record 2 more ATSC signals.) [The Hauppauge HVR 1600’s were the type that supports QAM and lacks the FM antenna connector].

I got a magma PCI expansion system so now I have 7 additional PCI slots. I got 2 used Hauppauge HVR 1600’s [they do not support QAM on the digital inputs and they have the FM antenna connector].

I would like to get 6 Hauppauge HVR 1600’s working, but is that too much for the PCI bus; will I saturate the bus? My worst case would be recording 6 ATSC shows, using 2 analog inputs to record stuff from cable boxes, and the remaining analog tuners would be used to send FM radio to extenders or my computer.

Thanks for your help

PCI bandwidth is typically 133MB/second. That's 1064Mbps. A typical HD TV stream will vary between 12-20Mbps. So, no... you won't saturate the bus with your PCI tuner cards.
