That's a good improvement.



I was messing around some more cuz sugarhell said he got to 4ghz at 1.050v on a 3770K. Hmm I thought...

4.2ghz (2133) @1.040v and its still going. I'm not sure, is this normal? I knew it took less volts but this is unreal. Btw, it's oc thru a vnc session. biggrin.gif

ssd- 500gb Samsung evo
case Corsair 900d
Cooling- h100I push pull
Ram- currently running some random old 1333 mhz ram 4gb (Picking up 32gb 2400 Trident X in a day or 2)
GPU- got a Wind force gtx 660 which ill give to my brother when they release the custom r9 290s I may end up with 2 or 3.

Back on topic.
i have been testing the Overclocks i can get on my 4820k. (I'm a beginner overclocker BTW First time i tried was about 3 days ago but been reading for awhile).

I was wandering if these were good specs on my OC-

Vcore 1.38v
4.7 GHZ on all cores (100x47 multiplier)
the temps at 100% loads reach about 47-50 C
The CPU seems stable even 100% load after about an hour stressing.
In CineBench i have a score of 823 (Base is 653).


When i reduce the votage to about 1.30V I cant get through Cine-bench it gives me a bug report every time.

I was also wandering If having bad ram could limit my CPU overclock.
Any one got tips on how i could get more of an overclock without spiking my temps (Or are there any good guides out there for overclocking 4820k's)

Thanks .
1.38 for 4.7 is really good thats my 2cents.gif for either 2011 quad

It could not run 1T CAS at all. A quick swap at Mircocenter, and all is good. This is my first ivy-e chip and I'm liking what I see. thumb.gif

My actual PC is a 4820k+Gigabyte GA-X79-UD3+8Gb DDR3-1600 (4x2)+HD 7970+Aerocool HorsePower 650W

This is the setup to 4.5 Ghz

BLCK 100 Mhz
K OC: Enabled
PLL Overvoltage: Enabled
Turbo Multiplier x45
Hyper-Threading: Enabled
C1E: Disabled
C3/C6: Disabled
Thermal Monitor: Enabled
EIST: Enabled

CPU Vcore 1.250v
Dinamic Vcore +0.080 (in idle 1.352v \ in full load 1.344v)
PLL: 1.810v
IMC: 0.940v
LLC: Turbo
Power Limit Turbo:300
Power Limit amps:300

Curiously for 4.2 Ghz it need only about 1.15-1.17v

Any idea?

Cheers

PD: Sorry if some word is wrong write, i'm spanish tongue.gif

Try raising your Power limit to say 500 ?

Yours is a average one so dont sweat it and or raising you vscca and vtt to 1.18v or the safe limit for ivb-e

4.7GHz on 1.38 Vcore.

I have achieved something i never thought possible........... In the last 48hrs i have managed to kill 2 RIVES in two days . UNBELIEVEABLE stun.gif

In shock about how ordinary those boards are wth.gif

first 1 lasted six hrs and no power up madsmiley.png

2nd one DOA no power up sozo.gif

No stock in brisbane ............ and bought a sabertooth ........... that wont do 5gigs @ 2400 madsmiley.png Just like the useless Giga UP4 what a piece of crap ..... lachen.gif

DAMN YOU murphy and the stupid apprentice yesterday at lunch time is with me in the van and need some juice from the servo ....so the idiot puts unleaded in instead of diesel doh.gif

I know right, I still am somewhat skeptical myself lol. I got 4.2ghz down to 1.032v and 4.5ghz down to 1.140v and stopped it there.

*Oh so far 4.7 needs about 1.240v. Now's that quite a jump from the volts at 4.5ghz doh.

I don't use sin's oc guides much because there's just tmi and it gets convoluted, especially since that guide you linked is for sandy. Though it's good for reference even for non-giga board users.

I like Raja's for Ivy-e. It's simple and straight to the point. And he shares their deep binning experience so you don't spend forever chasing ghosts.

Overclocking Ivy-E for the masses is centered on two voltages: Vcore and VCCSA (more on VCCSA later).

nothing.. 4.5 Ghz with 1.364v prime crash in 2-3 min, i will stay in 4.4 Ghz @ 1.284v how is the max safe voltage for VCCSA/IMC?
post #5569 of 6491
Thread Starter 
It should be about no more than 1.2v

Not many 4820's can do much more than that on those volts .
Like i said yours is a average chip
post #5570 of 6491
So I have just finished overclocking my 3820 to 4.625ghz @ 1.375v. I ran a 16 hour blend test on prime with no issues and temps stayed under 75 with my CPU cooler running on silent. I do not have my ram in XMP as I was noticing some instability. Although my prior tests did not involve me changing my CPU Strap. Now that I am using CPU strap maybe XMP will work better. At the end of the day I am pretty happy with my results so far. Along with my overclocked Titan at 1250mhz on air biggrin.gif

Would anyone be able to give me some input as to how I can get closer to 5.0ghz? My rig is in my sig if anyone wants to check out what im running. Any input would be greatly appreciated as I don't really understand the other in depth options available in my bios and I dont want to go changing things that could potentially ruin my CPU

Always appreciated
