Will this accept an LGA 1155 Celeron CPU?

I am running the Intel Pentium G2130 Ivy Bridge just fine on this motherboard. The CPU type lists that this board can run Celeron (LGA1155) CPUs. Your only restriction will be on memory overclocking. The memory specifications lists: DDR3 1066/1333/1600/1800*/2000*/2200*/2400* MHz (OC, 22nm CPU required) All the speeds listed with * will require a CPU that has a 22nm transistor size. CPUs that should work on this board BUT WILL REQUIRE AN ADDITIONAL VIDEO CARD: Intel Celeron G1610 Intel Celeron G1620 Intel Pentium G2130 Intel Core i5-3350P CPUs that should work on this board and have integrated Video: Intel Celeron G1630 Intel Pentium G2010 Intel Pentium G2020 Intel Pentium G2140 Intel Core i3-3220 Intel Core i3-3240 Intel Core i5-3470 Good Luck!

My PCI-E 3.0 x16 slot is only reporting as 1.0 instead of 3.0. How do I enable it for 3.0? I've updated the BIOS and drivers already. Thank you.

That is curious. It seems my mobo is running at 1 as well, instead of 3. I will report back if I find a fix.
