This is the extreme cooling.

The i7-3770K has at least 200MHz better OC headroom than i5-3570K.

All cores will run at maximum turbo speed.

I wonder what is the safe range for both voltage and temperature?

According to the link, 1.52v falls within the safe range?

i try 1.62v to load 5.3ghz

Don't tell me you did it with air cooling.

Ok, done testing at 4.8GHz.

My Corsair H50 can't take it anymore.
If I were to run OCCT, I bet it can go up to 105c.

Besides, I don't feel comfortable with such high voltage.
I think it is the max it can go.

Added on May 19, 2012, 4:10 amJust to give you an idea how far i5-3570K can go.
4.8GHz generates alot of heat. You need pretty high voltage too. High end cooling is a must (i.e. customized water cooling)
4.7GHz is attainable for 24/7. You don't need watercooling. You just need a better HSF with good air ventilation in the casing.
4.6GHz @ 1.3v. Load temperature is about 80c. Both temperature and voltage fall into safe range for 24/7.
The sweetest spot is 4.5GHz @ 1.25v. Easy freebies at finger tip and very doable. Temperature under load will not exceed 75c.
4.3-4.4GHz, most pariah motherboards with NO vcore setting can hit that range. Load temperature does not exceed 70c.

Finally get rid your gigabyte mobo eh?
U poison me to get that board. but Im not a fan of matx board.
btw how much the market price for h50? im interested seeing you achieve high clock on this cooler. how would h50 compare to noctua nh-d14?

water cooling boss

ivy loved high voltage. but the only problem is... WHY INTEL USING CHEAPO THERMAL PASTE INSIDE THE DIE!!! 

i use my hand to touch and feel the water block.... no heat at all but temp show 78-80'c 

My Bios set 1.365, but CPU-Z show 1.248.
So far 4.5Ghz @1.248(CPU-Z) stable @ 80c with H100

My Bios set 1.365, but CPU-Z show 1.248.
So far 4.5Ghz @1.248(CPU-Z) stable @ 80c with H100

LLC kicks in on loading.

What you mean?  . And by the way, actual voltage from bios or CPU-Z?
EDITED: Just googled it, well, so what i'm going to do now is lower the vcore in bios and set the LLC to maximum right?

i gonna do operation on 3770k tonight

Tell us how it goes. Show us step-by-step on how to do it too.

  ... i now using pen-knife to slow slow open up.     

Added!

Gratz on buying a better mATX board. IB loves subzero cooling.
I have ordered this not-so-extreme TEC block for my IB. ETA next week.



Quad TEC + Dual Controller - RM1.8k shipped 

i gonna do operation on 3770k tonight

Tell us how it goes. Show us step-by-step on how to do it too.

share the process pic and guide pls... 

Walau.. dat is imba cooling solutions... For anak2 Dato'. Tapi, bukan ke produk tu masih dlm r&d lagi..?
Make youtube videos... Like! 

    jus finish operation   

good news is... the proc still awake... hahahaha

Are you going to run it with the cap on or you prefer it naked? 
Please share the temperature readings and overclock results.

What sort of pen knife did you use? Can show us the picture of the pen knife?

now running with "cap"
i will test with 2 different type thermal paste

1. IC diamond
2. MX4

btw.. my golden i7 was kill by tnb and now i got the bad chip with modify cap.
here the new result 

result drop about 10'c 
before:- (in bios monitor)
1.62v - 74c-76c (5.2ghz)
1.64v - 76c-77c
1.68v - 78c-81c
1.70v - no boot

after :- ( with ic diamond)
1.62v - 66c-68c (5.2ghz)
1.64v - 66c-68c
1.68v - 68c-70c
1.70v - 70c-72c (5.3ghz) 

what my exp told me is, u need to add 0.08-0.1v for the next multiplier. seriously IB is voltage suc|<er!!!
