4x4 vengeance 1600 c9 1.5, corsair a70 cooling,
X20.5, bus 200, pcie 201, ram standard setting@ 1600, vcore 1.45(vid 1.375), max temp after 30' blend test 55 (vcore 1.5)
Other setting are standard:
C1e and c&q off, CPU PLL 2.5, ht link 2000, nb volt 1.1, ht link 1.2

Is not very stable...gaming on Facebook > blu screen!

My question is: how lowering temp working on ram (I've never oc'it and so no experience) or other settings.
Optimized @4.127 how I can go to 4.2?

Many thanks!

You have to make sure that it is indeed your CPU that is causing the instability. The first thing to do is drop to stock clocks, set your RAM to it's recommended settings, and make sure your memory is stable. Run Memtest for a few hours to see if you get any hours and then just use the system as it to make sure it's stable. Assuming that checks out start overclocking and see how far you get. You should set your HT link to 5x (1Ghz) before overclocking to help with stability and only raise it when you meet a final clock speed for your CPU.

Testing ram is the first thing I do after every workstation assembling, so in this case no ram problem. I'll test ht link at 5x.
What's regarding other setting?

Well try it and let me know. Just keep in mind that you may not get stable at that speed no matter what you do and will have to settle for a lower speed.
