Thanks owikh84, time for OC learning hehe. Will post my benchmark here if I succeed lol

Overcloking is not that hard if you read the guides in the first post of this thread.
Good luck!

wah.. owikh84 damn geng

2600K and Z77 V Deluxe user here !!


Previously was using P67 deluxe, gave my sister ( i5 3470). Such a waste lol .. Dafuq

Hi all,
I newbie in i5/i7 overclocking.
Currently using i5 2400 with maximus V gene.
Got question,I already up the multiplier to 36 for all core (31 is stock multipiler)
When I boot into window,initially all core is crank up to 3.6GHz during stressing using prime95.Then after a minutes,all core is drop to 3.1GHz even though there is no error during stressing.
Why ar?

Overheat? Pls kindly share with us some screenshots of the priming.

Not overheat since the max temp is 45 worst among 4 core. Didn't capture the priming.later will do that.

Just notice,even with stock setting in BIOS.the frequency only go up to 3.1GHz ,which is weird cause it can go up to 3.4GHz.Any comment?

I just recalled that it is a 2400 so actually it is normal because 4 cores will run at 3.1GHz.
Turbo @ 3.4GHz will only kick in when you are running single/ dual threaded works.

I see,so if i want it run over 3.4GHz,since the multiplier is up to 38, do i need to disable 2 core?

You might give it a try but I don't think it's a good idea to disable cores. Not worth it.

i just OC my 2600k too 4.4 Ghz, just to play fsx, z77 asrock extreme 4 user here, if i try 4.5Ghz always BSOD ( clock watchdog timeout) but i satisfy already with 4.4...

just buy apacer ARES 2400 CL11
But my pc can't boot if I select the speed 2400MHz,after adjust to 2133MHz,then can boot. Why ar?If I do not manually select,the speed is 1600MHz stock.

I think you should enter the RAM timing manually.

Frequency: 2400mhz
Primary timing: 11-12-12-30-2T
Voltage: 1.65V

When i select the xmp profile,the ram speed is auto.select to 2133MHz.anyway later will try it

Already try manually enter,PC can't boot
By the way,if I put max multiplier to 35 for all core, all core can go to 3.5GHz during stress .
The voltage is remain at 1.128 during idle and stress,is it cause I manually enter the voltage?

Back to the RAM question,is it got connection with IMC from the proc?
Official spec from intel memory support is 1333/1066 MHz.

The behaviour of vCore during idle and load either vdroop or vdrop depends on the Load-line Calibration aka LLC set in the BIOS. Very High Level will give a minimal vdroop/vdrop that's why no big fluctuations.

IMC is built in inside the chip so there is a huge connection between them. The Intel's official RAM spec is based on the their test specs ensuring base functionality. Hence, it doesn't mean that you can't use a faster memory kit. But take note that Sandy is capped at 2400MHz.

You mean, capped at 2400MHz,is it all Sandy Bridge proc capable archive to that speed or only K series proc?

Oops my bad. I just recalled that SB's IMC can't do 2400MHz altho there's a 2400MHz strap in the BIOS. My highest achievement was 2333.

Owh,that explain . I thought maybe the ram is faulty or what.
