I have an AMD FX8350 Paired with a Cooler Master Hyper 212 Evo.

I was wondering what voltage/ Frequency of the processor would be safe.
I've been overclocking it a bit, and messing around with it, however, I'm not sure what max voltage I should go to with this cooler.

Also I have Corsair Vengeance ram @1866, is it possible to overclock this ram, and what timings, as overclocking ram is completely mind boggling. I've heard its pretty terrible when it comes to overclocking.
 
What motherboard and PSU have you got?

I have an 8350 stable at 4.7GHz at just around 1.4V. It will go higher and the maximum recommended voltage should be just above 1.5V. At 5Ghz mine will be about 1.52V but it will not complete prime at that frequency.

You can OC the ram by adjusting the bus clock above 200Mhz. You will need to raise the ram voltage to 1.6-1.65V to maintain stability.

Make sure you monitor the CPU temps when testing and the maximum temperature should not exceed 62C.
 
Take the voltage up bit by bit as you increase the multiplier checking temperatures.

I had issues when overclocking before i switched to my current motherboard due to the power consumption of the chip when using prime 95. The VRM's were getting too hot and i was getting throttling and a ever changing voltage. What motherboard do you have?

With the poor voltage drop on my old motherboard, i couldnt get it stable past 4.4 but then i switched to a Crosshair V formula Z and have it stable at 4.9 for a 24/7 clock. It would boot up at 5.2 but no prime passing and i would get about 15 mins of prime at 5.1 before prime would stop one of the cores.
 
Keep the RAM at stock or even below stock via multipliers for a start and find the maximum Clock on your CPU keeping Vcore under 1.525v and CPU NB 1.425v. All other voltages keep at stock.

Do this by simply raising the multi first. Then when you find top multi do HTT and lower RAM divider.

Once you have done this work on your RAM. Remember to disable all powersaving and keep an eye on temps.

I have Giga UD7 and ASUS Crosshair both great boards and this method works on both.

My CPU is stable on air at 4930mhz ish 1.525v / 1.4v 220HTT memory 2100 ish Cas 7 tuned for Vantage efficiency.
