If the Corsair modules were running @ 11-11-11-28 1600mhz and you've hot swapped the modules and not adjusted any settings in the BIOS, then yes I'd wager it'd have a lot to do with your issue. Essentially the BIOS still "thinks" that it's the Corsair Ram.
I'm d/ling the manual to check the exact location of the timing adjustments, but the timings shouldn't be hard to find. You'll be able to spot them in the DRAM area as they'll show as 11-11-11-28.
The first three CAS settings should be adjusted to 9-9-9 and the 28 changed to 24
What revision is your board?
Attached in the zip is the F7 Bios file extracted from the .exe it's for revision 1.0, 1.1 and 1.2
Extract it and place on the FAT32 flash drive in the root directory (ie no folders)
