(Q) Is my over safe? 3570k @4.0

[bergami]

Config:

3570k @4.0 at 1.145v (stock)
4x4 Corsair Vengeance @1600Mhz at stock voltage
GA-Z77X-UD5H F14
Seasonic SII 620
antec water kuhler 620

These are pictures of idle (Before run Prime95 or any app/game)






Should I run prime95 with these settings? How long?

The first pic shows 4000mhz and 1.200v , is this idle ?

Anyway if you mean auto voltage setting = stock=1.144

You could probably go 4100 or even 4200 on that voltage (auto), after that you probably need more by either offset ,manual or boosting turbo voltage if MB supports that .From stock to 4.2 you don't need much increase of voltage but once you get above 4.2/4.3 you need to add a lot more each step .

As far as how long, well min IMO is like 4hrs and 12-24hrs to be sure , but honestly you just got to try with app/games to make sure.
You could pass prime95 for 24hrs and crash os some app that uses different type coding than prime , but chances are good it be low % of this happening .

In the BIOS it is set 1.145v (Auto)
Idle is only Firefox running

What about the temps?

Sorry, since you didn't run prime yet I didn't look in first post above .

If those are idle temps no load there high , but your not idling at 1600 , do you have speedstep disabled ?

You should be at around 0.940v@1.6ghz ilding and temps should be low 30c or maybe 5 over ambient .

Make sure you have balanced power option in windows .

I get 63c max on default prime95 setting @4.0 and my voltage is around 1.120v , thats air cooled with 212evo

What is speedstep?

This is full stock idle, temps:

Ok , that is good now with speed and voltage but your to hot .

On water block did you make sure you tightened each corner a tiny bit at a time . you might have one corner to tight, making the block not matting flat with core .

Speedstep is a Intel feature, it lets the CPU go from idle (1600) up in steps , don't confuse with turbo as thats anything above 3.4ghz for your/mine chip .

What's your room temp now ?

 

[bergami]

I guess its my ambient temperature, my country is really hot (27ºC now) and my case isn't very good.

Ok , try this with prime as quick test .

Start prime95 you should get pop up box and set thread count to 2 instead of 4 .

That will multi-core all cores to like 50% , see how heat is , if not bad then try 4 threads , all cores .
If you see crazy temps like 90c you can exit /stop test easy .
I get like mid 50c with 2 count and all 4 count like 63c with room temps of 22c .

Here, quick 10 min test:

ok, so you getting 60-61 , that is totally ok .

try 4 count now, my guess you get 68-70c or so which again is fine.

That is on high side but with 27c room and not sure on your case flow .
you have it exhausting out back fan mount of case ?

Does temps go lower with side panel off ?
Also does antec have software for fan/pump or you just plug into fan headers of MB .
If so you might want to see how your MB can set a fan profile for the fan, to ramp up speed when temps go up .

Yes, my water cooler has two fans exhausting out of the case;

What side panel?

Antec doesn't have any software for this cooler;

Later I will try to find something like a "Turbo mode" for the fans in the BIOS, there might be something there

I meant to see if you get lower temps with case side cover off .
There should be fan adjustments in bios .

 

[bergami]

There is a big fan at the side (120mm). I can't open it because I live by the sea and the corrosion would eat my hardware

 

[bergami]

I've set the Fan Speed to manual and put them at the maximum rpm I could, here is my wPrime score:



This is the Fan control of my BIOS:

 

[Ed1]

Thats fine, looks like slope PWM with be good option if it allows min/max at a specific temp (probably only works with 4 pin my guess .

When you run wprime are all cores 100% usage ? ( I never used it ).

Anyway your fine on temps , the reason your little high is looks like your hitting 1.200v under load , that a bit high on avg but every chip is different . I would of think something like 1.12-1.14 would be plenty .
Did you mess with LLC (load line calibration ) ?
IMO there no need to if you did for so low OC .

I played several battlefield 3 matches and the highest temp. of a core was 72ºC
Everything related to voltage I left on Auto
I ran wprime at 100%

I guess 1.200v is quite unecessary too, the system is setting it really high, I will try prime95 with lower voltages and see if I can keep the system stable and lower temps.

Btw I am following this guide:

If you didn't mess with LLC or any voltage , you can try lower offset something like -0.020 and see how it goes , under load you only need like 1.15 max i would say for your OC of 4.0 .

Curious what was it going to stock clocks ?
whatever that was 0.010-0.020+ is all you need over that .

 

[bergami]

Stock voltage is set at 1.150v

 

[Ed1]

I see well thats why it's going to 1.200 .
My chip at stock clocks is like 1.072v and goes to like 1.120-1.28 in 40-4.2 range .
So the chip in your case thinks it needs more your VID is probably higher than mine (you can view that in Core temp or HWMonitor .
but if you want little less voltage-heat you can try lower it to 1.17 with offset value (-0.30) should get you there .

You could maybe get it lower to but you would have to test stability if you try like 1.10-0.1.12 range but it could very well run fine .

Check his chart (power,Temp, voltage scaling versus freq ) I have seen others say even 1.00 for up to 4.0ghz

 

[bergami]

I've set the voltage to 1.180v but... its weird...



CPU Z shows another thing... but temps. are a little lower

Is that manual vocre (it stays that voltage at idle too) ?

try running prime95 you might not be loading it high enough with wprime .
I know when I try SuperPI my voltage doesn't reach max . It could just be Vdroop as your not using auto anymore .
Edit: Just tried wprime and it doesn't load CPU enough to see max vcore voltages , I get 1.104 which is 0.020 lower

But that is good place now IMO, I wouldn't try to get the very lowest as temps will only go down tiny bit and you then have to check longer for stability (anything in the 1.120-1.150 is fine IMO )

 

[bergami]

Very very weird...

Even with the voltage set at 1.180v, my Prime95 is running right now (44 minutes for while) and the temps. are ok, cores at 71/72/68/69 and package at 75ºC.

No problems with stability, I am browsing, watching movies, videos etc and everything looks fine.

Although, with CPU at 100% CPU-Z shows 1.104v and HWmonitor shows 1.107v.

Is that normal?

ok, you mean you set voltage manually (the top vcore option in bios) to 1.180 but even in windows with prime95 running you get 1.104 ?

That would mean you have a lot of Vdroop .
There 2 things you can do if you wanted a bit higher .
One would be just raise it to 1.185-90 , the second thing would be raise LLC one notch from auto to next step .
That would bring it tiny bit closer to what you set in bios (a medium setting on Asus MB brings it very close to the same) . I don't know on your MB but you wouldn't need much with such low OC .
Reading that lick a setting of LLC to med would get a small drop .

So HWmontior max column is 1.107 ?
And does it show 1.180 at idle, no load ?

 

[bergami]

Maybe it was a bug before, because now that its idle CPU-Z shows 1.140v-1.152v

 

[Ed1]

That's fine, I would leave it
