I5 4670k over clocking help

[Th3Architect]

Ok so I've watched Linus's over clocking guide on YouTube for Haswell and followed it to a t, however once I get to the adaptive voltage bit it all goes wrong, so for the sake of a bit of extra power I've decided to just use manual mode for the voltage, but this brings a new prob I'm hoping someone can shed some light on.

I set my manual voltage to 1.200 and that's what I get, high heat output though so I decide to tone it down to 1.180 instead in cpuid I get 1.181 so I try going down to 1.150 instead I get 1.152 why is my m/board or CPU which ever it is over volting my CPU even though I'm in manual mode?

Thanks for any help been doing my head in for ages!

You probably have your LLC set to extreme, it over volts by a bit to counteract the vdroop under load

Drop your LLC to high or medium and it won't be overvolted at idle, but it will droop a bit under load

Offset overclocking eliminates both of these issues

Thanks for the quick reply MrBucket, i just tried putting it to 1.135v and its running at 1.133, so this time undervolting.

 

Just so I know what exactly is LLC and is it adjusted in the bios or somewhere else?

 

I don't understand how offset works if you can give me a bit of detail maybe with an example it might help me understand it better.

 

Thanks again for the quick reply

1.2v should never give you high heat output on that cpu, period. 

Check your thermal paste and heatsink to see if they are ok. 

Update you bios and check if your airflow is ok.

 

Put VCore voltage at 1.2v

Put Input Voltage at 1.9v

Leave the other options at auto but for these option manual is the best you can get.

 

btw, what is "high heat output" for you? What are the temps?

 

EDIT: LLC, mentioned above, means load line calibration. It tends to give a little more power to the cpu when low v spikes occur. Try having it off when ocing

[LogicalDrm]

Hmmm... About how LLC works. I watched the TTL 1150 OC guide where he states that having LLC in anything other than High/Extreme will shift volts. Only High and Extreme keep volts to what they are supposed to be set. Would this be changing per boards? Guide (and my) boards are Gigabytes.

Hey thanks for the post Papeles, when I say high heat output I mean higher than I would like while idling, I'll explain.

 

In my comp room there is another PC (my flat mates usually on) as well as my server (on all the time) this can cause the room to get toasty most of the time and last night I had my PC on and it was just idling at 57 degrees celcius which is too hot for idling I would say.

I really just want a stable overclock with reasonable heat output, I should add I'm in a bitfenix mini itx case aswell so I know my OC isn't going to be great and really it's just this extra .001v here and there that are bothering me, I wasn't sure if it would cause any damage or something. I will try find LLC now and turn it off see how that goes.

 

Thanks again

[Th3Architect]

Ok so there is no off for LLC only level 1-8?

[papeles]

does the bios show u any desription? try going for the lowest. Those temps are actually high. Keep in mind that your case must be perfectly set up in order to be properly cooled.

 

I'm using the same CPU as you, clocked at 4.4/4.2 with 1.23v core and 1.9v input. My temps never go past 68º with room temp usually being around 20º.

 

You should also check:

case cooling, to see if you got proper intake and exhast. 

Proper thermal paste

Check if any app is making ur cpu be used when idle

Check if windows power state is on Balanced.

bios: those voltages, LLC off, turn on all haswell features like speedstep, c-states  etc (they don't interfere with overclocking)

 

I rly don't understand how you have those temps when my cpu idles around 35º

[Th3Architect]

Cooling isn't a prob really I have awesome cable management with a 200mm fan up front a 120mm exhaust and a decent aftermarket cooler with arctic silver 5 paste everything is done correctly. I think those temps were due to the fact the room was hot although it's getting that way now I'm running aida64 and furmark now with vcore at 1.140 and bsod literally 2 mins ago.

Going to try LLC on level 1 and 1.150v on CPU and yes the description on LLC is this- the CPU working voltage will decrease proportionally to CPU loading. Higher loadline (level) calibration could get higher voltage and good overclocking performance but increase CPU and VRM thermal. Select from level 1 to level 8 to adjust CPU power voltage from 0% to 100%.

Based on that would I not need it at level 8 to OC?

[Th3Architect]

Oh I'm getting 35 degrees in bios on idle as we'll not sure if the OC is actually applied while in bios though??

the slight over volting you desribed is perfectly normal.         + \- .002V is normal for this platform, dont worry about it.

 

use HW monitor to accurately monitor voltage, cpuz is not a very reliable monitoring tool.

Hey thanks Prokon, that was my main concern, just out of interest though, any idea why it does that?

sorry what does what do lol?

 

+\- .002V doesnt do anything certainly wont affect temps

[ProKoN]

it has to do with the FIVR. dont worry about it, its better than having Vdroop like we experienced on previous platforms

 

LLC doesnt do much of anything on Haswell + z87 or z97

lol just installed hwmonitor got 108 degrees on mainboard???

 

do i need to be backing off?

Thanks for clearing that up

 are you reading a centigrade or Fahrenheit value? whatever it says dont sweat it.

 

4.2ghz i would say you should be pumping it up not backing off lol

 

the mainboards on this platform run really cool even with a aggressive OC

 

the two important stats to monitor are

 

 

 

CPU Vcore- this is the actually Vcore being applied to the cpu

 

VID- this is the Vcore value you input in the bios.

Lol pumping it up I like that 

 

It was celsius i was reading but it's cool I think I've stopped all my stress tests and it's still showing that must be a faulty sensor or something.

 

Well I put 1.150 on the Vcore value in bios but Aida64 CPUID is showing 1.152 (which you said is expected) and my VCORE is 1.776V is all this looking fairly normal?

 

I know I have headroom for a better OC but it's just getting into summer here and this room is heating up already so I just want to get it stable at 4.2 really

you could always give my guide a ride.

 

Its a bit more thorough than Mr.Linus's guide

just ran cinebench and it pulled 1.808v on the VCORE

[ProKoN]

lol post a screenshot please.

 

1.8Vcore, that aint right. your chip would prolly die at 1.8V +

you may be looking at PIV values.

lol whats best way of putting a screenshot in here, I've already taken a snip of it
