Test it at 4.8ghz at 1.3v and go up in small increments until its stable same goes for 4.9ghz then 5ghz but keep a eye on temps and try not to exceed 1.4v for 24/7 use.
to be fair 4.7ghz is a good overclock if your happy keep it there and just save profiles in bios for higher ones, your cinebench score should be a bit higher.

claude plz don't run 20x ibt!!!!
5 is sufficient,it will torture your poor cpu and it proves no more than 5 runs would prove

Resize your pics or use the spoiler tags.
Pics can be no wider than 1280X wide if you do not want to use spoiler tags.

delid done 
update soon 
-----------------------------------------------------
Temps under intel burn test 5 runs gained 20c under load LMFAO
and 3c under idle.
---------------------------------------------------------------------
Aida 32 57c max load under its stress test
---------------------------------------------------------------------
man my nerves where wreaked when deliding
my finger slipped and i hit my thumb with the hammer lmfao, then i couldnt find the right peice of wood as all the wood i was using seemed to dig into the chip, i think i took off half a tree and all the splinters landed on the back side of the cpu hahaha
suffice to say nerve wreaking, but i persisted....
-----------------------------------------------------------------------
Delid pictures
i used varnish on the vrms/ic`s seemed logical, i stuck to what people where saying and to not use silicon incase i needed in the future to reapply.
as you can see from the 2nd picture i almost crushed the ihs in the vice lol
though i checked elivation and it was fine

As it turns out my cpu wasn't stable at 4.8ghz with 1.31v. Was fine in Cinnebench and BF4 for 6 hours but fails on Asus Real Bench. Tried upto 1.35v and still fails Real Bench.
Dropped it back to 4.7ghz and currently working the voltage back. Its at 1.26v at the mo.
Are there any other volts or setting I could change to try and get it stable at 4.8ghz? Currently I've just set the cpu voltage to normal, using cpu offset to change the voltage and I've set ring voltage at 1.2v with uncore at 4.4ghz.
All C states and EIST are still enabled with turbo multi set at 48.
Any recommendations?

I think you will likely need more CPU vcore volts, if 1.35 isn't enough then I'd call it a day and settle for 4.7

could try more memory controller voltage,could be failing on that also
power saving shouldn't affect stability imo

VRIN is your best friend
try putting that @1.9 if no go then 2.0 if no go then 1.250v
give that a try
VRIN is different to vcore so make sure its up @1.30v.... also.

Cheers. 4.7ish looks to be my highest stable clock.
What temp are you getting under latest Prime95 Small FFT Virus2k? I've delidded and running naked core with EK Supreme and still hitting 90C in that.
was hitting 100C within a second before mind.

check the thread above this, BTW something is wrong with your method of applying the paste or heatsinks. or your heatsink is not flat..
68c max is what i see in INTELBURNTEST @4.8.
