... ever still be considered relatively stable?

I have recently rebuilt my rig and done away with my custom loop in favour of an AIO (Corsair H115i), mainly for ease of use after I got scunnered with finding all of my Koolance QDC's had corroded and become unusable (well over £150 on those fittings alone).

Anyway, keeping the same settings in BIOS I decided to mess around and check temps and stability as obviously the cooling capacity has reduced a bit.

I appear to have a small stability issue with Prime95 which is BSOD. My board is a ROG Maximus VI Hero with a 4790K overclocked to 4.7Ghz. It passes Real Bench with temps getting mid to high 60's, which doesn't seem excessive to me.

So is it just a case of using the machine as is until such time as I run in to stability issues in day to day use, or will I continue to try and tweak voltages to try and stabilise it to pass a Prime stress test?

Bare in mind I am a bit of a noob when it comes to overclocking and was quite rough and ready with it previously.

Vcore according to HWiNFO is 1.264v (1 of cores is showing 1.280v)

Thoughts?
 
Just drop it to 4.6Ghz sounds like it will make it stable, better IMO to run 100Mhz slower than getting a BSOD in the middle of something important
 
I recently OC'd my first CPU and read a lot about what stability tests to use and, following advice on these forums as well as others, settled with 5 passes of RealBench bench marking test as being stable enough for everyday use.

Saying that I don't actually get instability with Prime95 on my OC, just scary high temperatures. If you're worried about it try backing off 100MHz.
 
Stability is not a cut and dry goal. Just because you crash on Prime95 (which is a pretty unrealistically harsh test), doesn't mean you'll crash in the real world.

My gauge for stability is a a few loops of Real Bench to confirm it's not going to crash 5 minutes after I leave the PC and an overnight run with Overclock.net's modified x264 video rendering tool.
 
My system is stable for everything I do with it, but running prime the cpu gets too hot and forces the system to reboot. My bottleneck isn't the cpu's ability to run at that speed, its my coolers ability to cope with the insane temps prime creates.

Nothing I use comes even close to hammering the cpu like prime does so I consider my system stable even if prime will eventually force it to crash. (haswell cpu)
