so Ive got my 4790k stable at 4.6 with 1.25 Vcore temps in prime95 small fttp were going to 75 on 2 cores does this seem alright?
4790k @4.6Ghz and 1.25 Vcore?

I would keep going. That is low temps and voltage so you may hit 4.8Ghz+. Normal use temps are probably not going to be as high as P95 either.
hopefully. Ive not tried for any more yet. It is benching well at 4.6 on the core and 4.5 on the uncore and seems pretty stable at the moment.
I would like to try for more as it does seem stable.
not sure if theirs any truth in it but I read the 4790k's from Vietnam overclock well... heres hoping..

Even when upping the voltage?
got to 4.7Ghz at 1.26V that was stable. tried for 4.8Ghz it ran real bench for 45 minutes then crashed but I had not put the voltage up.
Ive currently got my cache set to 4.5 is there any advantage or drawback from having this up?

Keep going. You have loads of voltage headroom left. I would be tempted to set vcore at 1.35v and try the 49x or even 50x multiplier now just to see if it boots. If it does test for stability and if stable tweak the voltage down. I can't be doing with this 100mhz steps anymore and the first overclock I tried on my 4670k was 4.2Ghz then 4.6Ghz then 4.8Ghz. I have gotten impatient with age.
Running the core and cache at 1:1 does have a small performance gain but you probably won't notice it in day to day tasks. I have mine both at 4.4Ghz and that and some other tweaks kept me at the top of the i5 rankings in the Cinebench thread until Skylake launched.

it doesnt feel like it at times.. been up since 7 this morning. Think I managed 4 and a bit hours.. that's pretty good for me to be honest..
yea I did jump from 4.6 straight to 4.8 then dropped it to 4.7. think I will try youre idea tonight once the kids are in bed..
