Does this OC look OK?

As the title says, is this oc ok?

I just used the built in 4770k set at 4.6 and that was all,

I have a 4770k, a gigabyte z87x-oc mobo, 16gb of teamgroup 2133 ram and a r9 290 flashed to 290x.

OC'ing the cpu seems to be too easy to be trusted? I just set one option in the bios? wow.
I am a noob to this to would appreciate some advice, e.g. if the higher frequency options that are available are safe? I assume there will be a certain amount of performance vs lifespan to be in effect?

The PC certainly seems to be quite happy at this, although the fans are running a bit harder,

that voltage seems quite high and i don't think you've tested it at full load otherwise the temps would be much higher. try running prime 95 or intel burn test and see what happens

From what i have read, the voltage being that high was what I was worried about#: turning of the boost thing in the bios gives me 3890mhz @ 1.155v
I just wondered if there was a safer way top get the same performance?

If your board allows offset voltage use that, but you need to find the voltage required in manual mode first.

As quick tests for stability i use
1st cinebench
2nd superpi 32
3rd asus real bench

Then the biggie BF4!!

I use AIDA as it seems to be highly recommended for testing Haswell.

But I would definitely start lowering the VCore until the system becomes unstable as I don't know if I would want to run it that high. What is your cooling?

As said above a good test is to run BF4 for a good long gaming session. 3/4 hours and keep an eye on your temps.

I have got my 4770K running at 4.4GHz @ 1.275 VCore and my temps are lovely. Mid 50's to low 60's in long BF4 sessions and fingers crossed stable for a few weeks.

OK, I have done some work now, basically taking these settings to get me started-

44 multi
Vcore 1.25
Cache 1.15
LLC top available.
DDR at XMP
DDR volts 1.65v
SA 1.15 or + 0.15 offset
IOD 1.15 or + 0.2 offset
IOA 1.15 or + 0.2 offset

(8-Pack posted them in this thread http://forums.overclockers.co.uk/showthread.php?t=18562552 - thanks 8-Pack!)

I then tried increasing the multiplyer, which was stable, but temps were sitting over 70C when running SuperPI so I returned to 44 multi. I figured there was headroom there though, so i have reduced the Vcore slighty and it still seems stable.

I feel quite happy here, and I guess I need to upgrade the cooling to go higher without raising the temps?

I have tried to OC the ram too using the 'upgrade settings' built in to the mobo bios. My type of RAM isnt listed in there though, do I need to update the bios - will it have more pre-set settings or should I just fiddle myself?
This is my RAM-
