Need help. I have no clue about memory frequency vs timings.

I recently bought some cheapo DDR3 2400 ram sticks for an A10-7850K build for my son.

Team Vulcan 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 2400 (PC3 19200) Desktop Memory Model TLYD38G2400HC11CDC01

I noticed that the timings are 11-14-14-35-48. I am no expert but these numbers seem way higher, I guess you would call it looser than my GSkill 1866 memory in my A10-5800 build. My question is this- would I be better off trying to tighten the timings and run at say 1866 or 2133? If so how do you adjust the timings? Is there a formula? Would you just start knocking back all the numbers by say one each? I want to learn about this. I just started tinkering with and building pc's a couple years ago after being Macs only since 1984. I have learned a lot about processors and motherboards on the AMD side but have avoided doing anything but leaving memory settings on auto.

You can try tighten timings at 2400 or lower to 2133 and tighten them there. I'm almost sure there are Hynix chips in this Team Group memory so try something like:
2133 9-11-10-28
2133 10-11-10-28
2133 10-11-11-28
2133 11-11-11-28
2133 11-12-11-28
2400 10-12-12-30
2400 10-13-12-30
2400 11-13-12-30
2400 11-13-13-30
2400 11-14-13-30
2400 11-12-11-30
2400 10-12-13-30

Hard to say what will work as there can be various IC but more than 1 from above settings should work.

All at 1.65V, Command Rate manually to 2N.
On APU series you can actually see some performance gain from higher memory clock.

Thank you for all that info Woomack. It is greatly appreciated.
