Well updated to the latest bios, which literally said RAM update dated from a week ago...
Everything seems fine now, no crashes or hiccups, though I haven't tried XMP again yet. Will try tomorrow, too late now.
Edit: beveling send that by using the Asus auto overclock turned XMP on and everything is running great.
Good to know it worked out. A friend of mine had trouble running his DDR3 RAM at 1866MHz until I updated the BIOS for him. I couldn't be sure it was the same for you, but it was worth suggesting at least.
Location is India , I know MSI GTX 970 Gaming is the best with best coolers in it but i wanted to make sure whether i should , Zotac is smallest a read a article on bittech , is Zotac really worse ?

Zotac has a reputation for being "cheap" and offering products at lower prices. I don't think it's entirely undeserved, but honestly anyone can have a good or bad experience with any brand. In your case, I'd look for what's available at a good price and has good support, in case you ever need to deal with customer support or warranty coverage if the graphics card is defective or breaks.
Also, that review article is a bit old. More GTX 970 models have been released since then. EVGA has their ACX2.0+ models for example, which more or less rivals the MSI Gaming 4G's cooler.
Which Zotac model are you talking about, exactly?
