hello guys.i need help with overclocking. i have i7 3820, motherboard msi x79a-gd45, 2x4gb + 2x4gb corsair 1600 mhz cmz8gx3m2a1600c9 ram and corsair h100i coolling.
i want to get it up to 4.3ghz - 4.4ghz. right now my pc its 30 c on idle. pls help me with the settings in the msi bios.

The 3820 multiplier can only go to 43, just so you know

RIG: I7-4790k @ 4.5GHz | MSI Z97S SLI Plus | 12GB Geil Dragon RAM 1333MHz | Gigabyte G1 Gaming GTX 970 (1550MHz core/7800MHz memory) @ +18mV(Maxed out at 1650/7800 so far) | Corsair RM750 | Samsung 840 EVO 120GB, 1TB Seagate Barracuda | Fractal Design Arc Midi R2 (Closed) | Sound Blaster Z                                                                                                                        Getting: Noctua NH-D15 | Possible 250GB Samsung 850 Evo                                                                                        Need a console killer that actually shits on every console? Here you go (No MIR/Promo)

This is why you should not get an FX CPU for ANY scenario other than rendering on a budget http://linustechtips.com/main/topic/286142-fx-8350-r9-290-psu-requirements/?p=3892901 | http://linustechtips.com/main/topic/266481-an-issue-with-people-bashing-the-fx-cpus/?p=3620861

You can simply set the multiplier (CPU ratio) to 43X. I'd set voltage to 1.25V (manual).

 

You can then mess about with the base to achieve higher, 4.7GHz is perfectly normal on that chip.

 

@thekeemo has recently been learning about OCing his 3820 and may be of help :)

i know its not full unlock but i saw some video that oc i3820 up to 5ghz....i want it aroung 4.3ghz-4.4 ghz... i need help with the settings in the bios

I dont think you can oc a non k processor by changing the multiplier. Only BLCK

My friend has an i7-3820 and it doesn't OC by multiplier.

I have finally moved to a desktop. Also my guides are outdated as hell.

The 3820 is overclocable just be aware that 105mhz and a multiplier of 43 doesn't work I'm currently at 100x43 because my chip wasn't too good but I've had it up to 125x36

If you have a better chip/cooler you can get it to 4.7 no problem

Thats that. If you need to get in touch chances are you can find someone that knows me that can get in touch.

False.

But isint it K only and this processor is not "K"

It has a limited ratio. It can go up to 43X and the rest is achieved by BLCK. Some chips can easily do 4.7GHz with a mix of multi and a 125 BLCK.

 

a lot of non-K cpus pre-haswell had +4 bins available as long as it could turbo

Oh wow, thanks for correcting me man :)

guys pls ..need some settings here

 

 

try this: 

BLCK 125

Multi 37x

Vcore offset mode +0.250

Set Memory profile: timings and DIMM voltage, leave speed at 1333MHz for now.

LLC set to medium

Please note that the voltage will be static with the 125 strap and does not drop

down to default or lower when the CPU is ideal.

 

The thing you have to decide is if you want the voltage to lower when you are

not using the CPU or not. If you do not then you use the 125 strap to overclock.

If you do want the voltage to lower then you use the 100 strap to overclock.

You could still reach 4.4GHz with the 3280 CPU assuming your CPU can manage

107 BCLK and the 43x multi. Remember it is all about cooling here. If your cooling

is not up to the task do not aim so high.

ok... iput cpu base clock 120 cpu ratio 35 ram 1333 mhz and and xmp enable , cpu core voltage 1320v and disable intel c-state.

but when i start the pc it turn off, start again and then start to open windows.... what is the problem? cpu core voltage? i want the pc to start immediately

It's probably failing to boot, then resetting and booting again.

I'd just set multiplier to 43, leave blck alone and set voltage to 1.25v manual

ok... iput cpu base clock 100

                     cpu ratio 43

                     ram 1600 mhz

                     xmp disable

                     cpu core voltage 1250v

                     enable intel c-state.

                     disable intel turbo boost 2.0

                     disable enhanced turbo

 

now its starting immediately

 

basic oc (from 3.6ghz to 4.3ghz) is gonna make cpu life shorter?
