It's a simple .009 btc from virwox and it's been 3 days. No idea what to do next   Suggestions?

I've had it, I've researched this inability to finish downloading the bitcoin core for a long time. I've rescanned, reindexed, removed and clean installed, mem checked, read lots of posts on similar issues. I'm ready to toss in the towel and just eat the ..05 bitcoin loss. It's in an Armory wallet btw and I'm using Bitcoin-Qt for the download. It's an i7 machine with 32Gb ram and an SSD not overclocked I guess it's my turn to post the last of the log file.  Please share your insight.   I'm going to bed.

I've been researching this multiple gpu thing for a month with no luck. I'm starting to think my mobo just won't do it. Looking for a little advice before I dig another old rig up and just run two single gpu miners instead of one rig and two cards.

I've got a stable GIGABYTE GA-MA790X-UD4P Mobo (Newegg Item=N82E16813128387), 4GB Ram, dual core 250 AMD something or other CPU and a decent 500W modular gold PSU running Win7-64.

I've got two GPU's, an RX570 and an RX580. I can mine either single just fine and pull 170W or 190W from the wall.  When I add the second card and power up I get no video. The rig just quietly sits there. I've tried different risers, usb link cables, GPU connectors, but nothing changes. I've checked Bios for something PCI-E related and only find a reference to BNG and BNG1 which didn't make a difference when changed.

I'm using the pci-ex16 and the x8 slots. The other slots did the same.

Hopefully it's just something I'm missing in the windows configuration.

Thank you
