Would anyone have some pointers on getting one of the mentioned adapters to work if cgminer is not accepting shares? I bought one and tried with a powered 16x riser. Windows recognizes the card, but cgminer won't accept shares. Interested to see how you got these working if there were any config changes necessary.
You resurrected a 2 year old thread? Honestly it's not worth the time or energy to get it working with so many proven motherboards out there.
Having said that, try increasing the PCI timer latency if it's available as a setting on your mobo.
My first parts purchase off ebay included an Intel wireless PCIe card that they guy told me was a pain to configure. This card include a PCI to PCIe adapter that works great for mining. Look for Intel Dual Band Wireless AC 7260 for Desktop and it includes the adapter.
Anyone jumping into crypto mining should consider upfront cost and look at getting older recycled equipment.
Example both these rigs have similar mining performance. New vs Old is double in cost.
Radeon R280, Latest DDR3 motherboard, SSD, RAM (all new) over $400 all NEW
Radeon 7950, socket 775/T mobo off ebay, 8 GB USB Stick, 1gb DDR2 ram (used off ebay/CL) less than $200
I'm currently running 3 rigs, all using 2008-2009 manufactured parts. I'm mining over 30Mhs for X11, X13, and Fresh. I stopped mining scrypt because these 3 rigs consumed close to 3000 watts at full speed. Freshcoin mining is consuming about half and thats 9 GPUS.
Also look at Dell Poweredge server power supplys around 700 to 750 watts go for less than $20 and a little work can easily power 3 cards. That way you can get by with a sub 500 watt PC PSU for your rig and run 4 cards easily. I'm using an HP and a Dell motherboard and both are solid.
