If I want to underclock my 2133mhz ram (Patriot Viper 3) to 1866mhz as I have 4 4gb sticks and my FX 8320 don't like them running at 2133, what would the best Timings be?
Timings at the moment is 10-11-10-25 Command Rate 2T
I've got it set to 1866mhz at 9-9-9-24 2T, anyway I can tighten them up a bit?

How would I know if it's stable or now? It will either boot or it won't?
You test for stability.
I start with memtest86+ overnight, at least several hours minumum. Then I move on to Prime95 small ftt's to test the cpu & cooling system but in your case I would run the Blend test, which runs lots of ram, instead. Be sure to keep an eye on your temps esp if you never tested before.
