My PC specs:
MSI 770 C35
AMD Phenom II X4 945

I tried to upgrade DDR3 from 2x2GB to 2x8GB (Kingston KVR1600C9D3/8G-SP).. I got this problem "CMOS Checksum Bad" when I tried those.
I already tried to reset / clear bios but still got the same problem.

MSI 770 C35 Specs:
DDR3 Memory DDR3 800/1066/1333/1600*(OC)
Memory Channel Dual
DIMM Slots 4
Max Memory (GB) 16

Probably overstating the obvious, but are your 2x8's in slots 1 & 2 (same slots the 2x4's were)? Many MBs aren't happy unless their memory slots are occupied in proper order.
Try booting with one, then the other of your sticks in slot 1 just to verify they both work.

Check MB again as Model MSI 770T C35 supports only 8GB of Memory.

If true MSI 770 C35, then MB will support 16GB of memory.
