I'm rebuilding an old PC that has 2x 1010 PCI cards in it, with the rackmount units and BNC linking their wordclocks.
I have a Mytek 2496 ADC feeding external SPDIF clock to one card, which is then daisy chained to the other via BNC. This is all configured properly in the M-Audio ctrl panel.
OS is Windows 7, i7 3770 CPU, 1155 slot motherboard, 16 gigs RAM.
I tried running the cards off their own clocks, before switching to the external spdif.
Playback in Windows works fine, it's only in Reaper that I get the nasty distorted ( what I assume to be ) wordclock sync artifacts, intermittantly.
The 1010's have had their power supply caps upgraded to 63v.
Bios settings have CPU throttling turned off, PCI bus power management off, etc
So it seems to be something with my Reaper config?
I tried using larger buffer settings in Reaper, am using M-Audio's ASIO driver version 6.0.8 which is the last one they issued.
I did see this thread where @JGrabowMST advised to use an older version 6.0.2 so I'll try to find that.
