Good CPU chip.
A good chip can give you extra 100-200MHz overclock headroom.

Quite good.

It can run as good as those customized watercooling with 2x120mm radiator.
It depends a lot on how you place the cooler.
If you place it inside the casing, make sure you have good air ventilation inside the casing.

i5-3570K need 1.4v to run 4.6GHz.

Should have got that 3770k, i went to Digital Mall and searched the whole stores for 3770k, none of them have stock. After i bought 3570k, then yoongkeen pmed me, he has 3 units on hands aww.. Diablo on 15 May , urgently to build a comp that time.
1.405 for 4.6 is a lot, i cannot pass prime 95 after one hour because of the temperature 104c, unless i set my fan to maximum which the sound db will like a hairdryer, then temperature is 84c.

With my H50, I need 1.4v for 4.6GHz.
Temperature is in the range of 80-85c under load.

Try OCCT instead of Prime95.

may i know some of your settings in Bios?
IGPU Load-Line Calibration you set Auto or 100% load.
Load-Line Calibration for voltage 100% load?
Internal PLL voltage enable or disable? Thank.

LLC 100%
Internal PLL enable

The intergrated GPU(iGPU) voltage's LLC auto or 100%?

I didn't touch the settings for GPU.
It is at default setting (i'm not sure it's "auto" by default or not)

Ic, default is auto. I found it is unstable if i put 100% for iGPU. Maybe i will set back to auto, thank for your informations

Managed to shave up 6s with MicroXP 0.86

owikh, put my OC result on front page please.

Playing with BCLK OC

3770K @ 5.0GHz = 104.2 x 48 | 2780 10-12-12-21


3770K @ 5.0GHz = 106.4 x 47 | 2766 10-12-12-21


sub 28s latency
3770K @ 5.0GHz | 2666 9-12-12-21

I might have a bad 3570k chip. My system still not stable with 1.45 and now increased to 1.47.

3770K @ 5.0GHz = 104.2 x 48 | 2777 10-12-12-21-1T

Nice......
Sensor pic.....? Vdimm,VCCIO,VCCSA,........

Max temp with SPI32 ?

1.87v, 1.25v, 1.2v
Didnt really monitor the core temps at this vcore but this 3770K is able to run 32m at 5.0GHz with 1.48v mac 82c.

Thanks.
82C on water,right?

Yeah that's under water.
Heat dissipation inside IB is damn poor due to bad TIM paste used.
I haven't run any 3D benchmark on 5GHz yet until now.
If everything's ok i will put it on my incoming Quad TEC + dual controller next week.

1.5V to run 5GHz 2C2T? that is real hot CPU.. lol

it still can shave with this timing and speed...

Budget GSKILL memory shine in Z77...

DDR3-2200Mhz from DDR3-1600 2x4GB

Continue, this time round mix and match. One pair 1600mhz and another pair 1866, 16GB running at 2300MHz CL11-13-11-34-2T @ 1.65V.
