I am trying to use a 4 gig chip of F3-12800CL9S-4GBNT on an Asrock Z77 Pro4 motherboard. Won't Post. Same speed memory I have in the machine. Just got this chip on eBay.
 
try some tricks: rub the contacts with normal paper (some people use a rubber, im "paper fan"), switch modules between them, (BTW, be sure all the RAM slots are working), (other question, did u see the board and the CPU (RAM controller is in CPU) "mastering" 4 sticks of RAM?
 
First mistake was not buying an identical stick.

But since you already did: Some boards are really picky about having matching CAS latency, timings, and actual RAM chip MFGs (Not as in G.SKILL or Corsair, but as in Hynix or Nayna who actually make the little black chips on the stick). Make sure they match, and if they don't, that could be your issue,
