I Purchased a rs3wc080 to be able to ad a lot of sas disks to my pc. It is a regular machine with Asus P9x79 mobo and i7 cpu running win7 pro x64.
The card worked out of the box, but during copy jobs of some size (30+ minutes) it would cause BSOD. After a while it would also occationally fail to start with windows, with error code 10 "this device cannot start".
I have flashed the card and the mobo with the latest firmware and updated win drivers but the problem was just getting worse. I've also removed the card, tried it with no disks attached, down stepped the pcie slot to gen 1 and 2. Downgraded firmware. Upgraded again. Using both console and efi. All with success, but without solving the problem. Currently the virtual disks are presented to the mobo bios, and all is fine in the raid controller bios. But in windows the disks don't show, and in device manager the card shows up with error 10 cannot start.
I even tested the card in my old pc, which has the older x48 chipset, and all worked fine even under hard load with robocopy. Since it worked in my old machine, which is running win7, I figured maybe my os installation was to blame. So I reinstalled windows, downloaded the latest driver for the card from Intel, and... Error 10...!!!!
Any suggestions? I was thinkng of returning the card as faulty, but since it works fine in my other pcs (I've tried three now with success) I guess it actually works. Just not in the machine I need to use...
