Hello.
Ran into weird issue with this motherboard. I wanted to use LSI MegaRaid hardware raid controller card in my machine. Initial setup looked like this
■First PCIe x16 slot - graphichs card (Nvidia Geforce GTX 660)
■Second PCIe x16 slot - RAID controller card
■Third PCIe x16 slot - empty
After booting up, I noticed that Win7 Aero desktop is feeling sort of sluggish and laggy while moving mouse cursor around the desktop. Reinstalled drivers couple of times, changed their version backward and forward - no change. Finally downloaded GPU-Z and noticed that it showing x1 (!) mode for graphics card.
After removing the Raid controller from motherboard, GPU-Z reported graphics card working in full x16 speed mode. Resubmitted raid controller into second PCIe x16 slot again, just to be sure and desktop became laggy again. Bunch of reboots/shutdowns in-between of course.
Finally, I found out that I could use raid controller in the 3rd PCIe x16 slot without it killing off graphics performance. Problem is, it's x16 size slot but working in x4 mode. That particular raid controller works normally in x8 mode (x8 PCI Express 2.0), so half the performance is theoretically lost.
Which becomes problem once I become upgrading my system to use SSD's in RAID0. More than couple of SSD's in RAID0 would saturate PCIe x4 available bandwith (planning to use Sandisk Extreme II's).
Final working setup looked like this
■First PCIe x16 slot - Graphics card
■Second x16 slot - empty
■Third x16 slot - RAID card
I'm interested if anyone has ran into similar issues with the PCIe slots using this motherboard, either using some other cards (perhaps PCIe SSD's or NIC's) or raid controller. And if they found any solutions better than using 3rd and slowest performing x16 slot.
I tried using graphics card in second x16 slot and raid in the first. Can't recall exactly what the result was but it did not work out.
