Members overclocks

Hi, I've never been big on overclocking and tend to run my PC at stock clocks. However I wanted to give it a go and having just done a bit and seeing the results I wanted to see whether my experience is mirrored by others and get some advise.
This link is a screenshot showing 3 results.

Todays result is the middle one and I put the cpu to 4.6 with the gpu at stock, The way I did it was I let my Z97 ROG hero board do it then I removed the ram overclock it did and put it back to 2133 and then increased the core multiplier from 44 to 46, Everything else is on Auto.

A while ago I tried adding some voltage to my Fury pro and that result is with a stock clock cpu on the left.

The test on the right is stock clocks on the cpu and gpu.

I was expecting the physics score to improve today but it is exactly the same as the test on the right and slower than the test on the left both of which had a stock clock cpu.
Is it correctly overclocked and how do you test an overclock for stability and what tests should I do to see the improvement overclocking it gives.

I haven't tried beyond 4.6 yet as I want to get a decent test sorted first and I'm also on an inexpensive air cooler and need to do it progressively watching temps as I go.

The system is:
Corsair C70 case,
4790k,
Asus ROG Z97 Maximus Hero m/b,
Pure Rock Cpu Cooler - 120mm,
2 x 4gb sticks of Vengeance pro ram (2133),
Sapphire Fury Tri-x (oc model)
TX 850 v2 psu.

The link shows the three tests mentioned above along with the cpu-z, gpu,z and real temp results from todays 4.6 cpu test.

I tested it out for ya. I ran my overclocked speed of 4.9 then your two mentioned speeds, then i also ran your overclocked speed again but lowered my ram from 2400 to 1333mhz as you mentioned you lowered your ram speed for the overclock.

4.4ghz = 12300 Physics marks
4.6 = 12765
4.9 = 13713

4.6 = 12313 with lowered ram speed

Even with the lowered ram speed the mild overclock comes out on top so i would hazard a guess that you maybe had something running in the background that effected your score.

I don't think anything other than those programs that are in the screenshot was running but I'll try again without them too, I'm going to re-install AB as well and do the gpu and see how it does, I might increase it to 4.7 as well, the temps seem good.
Thanks.

EDIT: I had expected todays 4.6 test to show better physics than both the others which were without overclocks..

Why not keep the ram oc? Even if the cpu can complete the calculations faster you need to feed it. So long as the ram oc doesn't introduce a lot of latency to allow the higher frequency the score you get should go up, as it does for BluD.

Haswell/DC you need to adjust the uncore appropriately to keep the system efficient for 4.6 try uncore at ~4.3-4.4.

Tune the memory at 2133-2400 too rather then raw clock speed.
