my ram is 1066 but i set in de bios 1600mhz... consider overclock? 

Er, how come? That's impossible, unless your ram is golden batch.
Even last time i used the Dominator, from 1600 to 1866 cannot even stable, DOMINATOR HEATSINK.

I googled, usually people can get 1.3- 1.35 24hours stable for 3570k, wonder mine why need 1.405 .

Good cpu chip? or motherboard chip?

But H100 conside a good water cooling also .
So Internal PLL voltage enable or disable?

my first run, voltage auto, prolimatech megahalems push-pull with cheapo cm 90cfm fans.

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.

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.

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

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

Ram runs on default XMP profile. 80-90 core temperature under load.

I didn't use stress test application to test for stability. I use Microsoft Flight Simulator X instead as this game is heavily threaded application. I have not seen any BSOD/application crash since 1.47v.

For the cooler, I'm using Corsair H80.

The crash occurred a few minutes while on the menu and sometime a few minutes while flying.
These are the graphic setting that I use:
[attachmentid=2862794][attachmentid=2862795][attachmentid=2862796]
Choose Simpang airport. This airport is surrounded by city area and 3D building. This should stress the system.
[attachmentid=2862803]

Hi, does anyone here have experience OCing on Intel DZ77GA-70K? Might be getting a 3770K + mobo + SSD combo as replacement for my trusty Conroe system. I'm hoping it's at least good enough to get the proc up to a range of 4.4~4.6GHz

Ivy bridge seems to release a lot of heat compare to Sandy...

just got my 3570k for few weeks, oc it to 4.0 with stock cooler.
prime test for few minutes, the temp reach around 90 already.
any sifu got ways to step down the temp?
tried step down the PLL to the Min and offset vol to +0.005v only, yet the heat... oh mai..

btw, my mobo is Asrock Extreme4 Z77
