Not bad at all, my booting experiences were similar to:

up to 4.6ghz - stock
5ghz - 1.25v
5ghz p95 stable - 1.35v
5.1ghz - 1.41v

Ive not gone higher, I think 5.1 is another vcore wall but we'll see once my new mobo arrives.

I felt the gap was too small to but after going slowly and pushing you can see it going in 1mm at a time, each wiggle a bit further. You will get it, mine had no scratches when I finished. hopefully you will not either. I have a noctua D14 and my temps top out in the mid 70's at 5ghz during prime 95 with 1.51v and since priming to get my stability right my max temp I have seen is 56 degrees from a heavy gaming session. De-lidding is worth it in my opinion.

Edit: I actually use a PLL of 1.603 and I find it more stable than higher PLL. Try lowering it and see if it works out well. Also are you enabling PLL overvoltage? That helps too when you have a higher multi.

I will try with lower PLL but it was ok 1.65 for me until 4.5ghz after only 1.8+ helped me. PLL overvoltage is ON , i found it better also.

http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/53054-intel-i7-3770k-ivy-bridge-cpu-review-23.html

all of that changes when you delid,
the vcores he mentioned are in relation with the high temps,
hence the, "even on the highest-end air-cooling",
i rather run a higher vcore with low temps,
then a lower vcore with high temps, both can degrade a cpu, no doubt,
personally i dont think mine will degrade noticeably if i run it 1.420V vcore 24/7
with low temps, within 3 years that is, with daily usage my temps wont go over 60C..

Filling out your rig in your profile will allow people to help you better.

My first chip was tight to the PCB as well. You basically have to find the best corner and be extremely careful. With your numbers I am not sure it will be worth it or not, it all depends on you. My chip was hitting 94c at 4.8 with less voltage than you, so it was a good candidate for delidding, but your temps are not that bad.

But I can boot with reasonable voltage at 5ghz and it crashes after full load and heat, and as far as i know more heat mean that its getting less efficient and needs more V, or I got it wrong?

That quote can't be more wrong...everything said in it is wrong.

-"Little more voltage for 4.5ghz?!" - My chip does 1v for stock or idle, and 1.27v for 4.5ghz - some people need 1.35v for 4.5ghz - what BS are they talking about there?
-Degradation comes over time, something that's NOT mentioned there - it isn't an overnight degradation of your chip
-1.25-1.30v HIGHEST usable voltage!? Do they realise STOCK left on AUTO goes up to 1.35v?

Man sometimes you read the biggest crap on the internet...
FYI: This isn't a dig at you, just the facts taken from that quote.

It is indeed a good video - I hoped to have made a video like that...but I screwed my chip...I'll update you guys as my mum's mobo and cpu are coming in very soon!

Being able to boot at a certain voltage doesn't really tell you anything. If you have done all the proper BIOS setup, and correct testing to find that your minimum voltage for 4.8 is 1.4v, then you could need over 1.5v for 5.0 to actually be stable, it all depends on where your chip hits the wall.

It is up to you if the risk of delidding is worth it to go from 4.8 to possibly 5.0. With Ivy Bridge chips there are very few people who do 5.0 or above on a 24/7 basis.

Yea I need extra voltage to do 4.3, 4.4, and I'm looking at over 1.3vcore for 4.5. Right now I'm failing at the 20+ hour on 4.6@1.4vcore, need just a tiny bit more. I might try to do 4.7ghz but that'll definitely require something like 1.5...

My temps are good though.

Be aware that voltages are a bigger factor than temps when it comes to degradation. If you got the features on that do stuff like less volt/frequency on idle, etc, you should be pretty good unless your doing something like compute workloads. This chip definitely appreciates more voltage though, as power hungry as it is.

I'm not kidding about folding being extremely intensive - temp difference between stock and CLU at this stage is around 14c -> not much
post #11229 of 33641
I found folding to be cooler than p95 27.7 by 15c...ymmv though.
I was using a Linux vm on Win 7.

TD, I suspect your pump may not be working properly btw, if you can rma that give it a shot.
