Hi ! I'm running 3770k with everything at stock on BIOS except XMP profile, CM 212 Evo, 2 1000RPM 140MM fans in the case (fractal design r4), and arctic silver 5
recently i did run Prime95 and did reach 65degrees and then slowly going up to 70, CPU-Z says the core runs at 3.9GHz, are these temps a bit high?

More about : 3770k temps bit high

Forgot to say i also run a 7870 DC2 that spins like heck (5000RPM max)

The temps were even higher with Intel Burn Test...
here's the Pic, please help :(

Is 1.3 voltage normal on Ivy Bridge?
August 26, 2012 1:25:37 AM

It now did a BSOD with Internal_Power_error, i did however press the power button when the screen wasn't responding just to see a BSOD, someone help me? :( 
August 26, 2012 1:38:13 AM

Can't delete or edit posts on this forum, anyway scratch the BSOD, it's a hibernating error that happens when there's too much data to store that's being used by RAM (which is 100% on this test), anyway should i lower the voltage? or what's the problem.

Is 1.3V the default on your chip or did you override it?

The normal load voltages are usually in the 1.15-1.25 range but the VID tables can vary from chip to chip, maybe you got one that has unusually high settings.

^Agreed...

1.3v is something you would generally see with 4Ghz+ OC's...

Did you change anything in the BIOS? Or pushed some "Boost" button perhaps?
August 26, 2012 9:22:37 AM

It's on auto, i guess Asus Z77 V-Pro boards prefer to have higher voltages? I dunno, should i lower it? also does 1.3Voltage mean +20 heat in Ivy Bridge?
August 26, 2012 9:23:36 AM

Forgot to post, how far can i OC with 1.3Volts, some people say u can go to 4.5Ghz with just 1.2? :S

i did a prime 95 on my i5 2500K, i OC it to 4.2 ghz, at stock volts, at 1.28v,

ivy bridge OC at a higher temps compared to sandy bridge, 65 to 70C at 1.3v is still ok

change the multiplier to 4.2ghz...
August 26, 2012 10:11:10 AM

Okay, new into OCing, so exactly what should i change except the multiplier? i've heard some people disable turbo boost and so on...
a b à CPUs
August 26, 2012 11:45:20 AM

ok, it's simple, just go to your BIOS.. (when u start your pc, just press f1 to enter BIOS)

and then go to core ratio and set it to 4.2ghz

4.2 ghz is the most stablest OC, no need to change anything, just disable turbo boost. thats all...

and reply me for inquiries.. :)

Voltage is on auto and jumping, shall i set it to something that stays the same? It does reach 1.3010 volt on Burn test, which accordingly to people you can clock 4.5GHz with this voltage, and 4.7 with 1.320, shall i change the voltage?

Mileage varies from chip to chip, there is no guarantee that your chip will be able to match others' under identical conditions. It may fare better but may also fare worse.

August 26, 2012 1:45:11 PM

let me tell u, the most safest OC is 4.2 ghz... 4.2 can be done with stock volts... if u want 4.7 then, u hv to do rounds and rounds of stablising testing
August 26, 2012 1:47:03 PM

It's not stock though, it keeps jumping, and goes as high as 1.3010, which means the temps can go 80degrees on load, shall i lower it or not, but do i really need that high voltage? >_>
a b à CPUs
August 26, 2012 1:49:08 PM

80 degrees? wow, maybe u have a faulty chip... or u set the voltage high at your BIOS
a b à CPUs
August 26, 2012 1:52:04 PM

it depends on the chip though, some are stock at 1.1 - 1.2 v... 1.3 is a bit of a concern though...
August 26, 2012 1:59:31 PM

1.3 at all 4 cores + 8threads on 100%, reaches 74-79degrees depending on core, should i lower the voltage to 1.2 manually? and clock to 4.2
a b à CPUs
August 26, 2012 2:20:55 PM

well, in the asus bios, try to set the vcore to auto.. and then up the multiplier to 42

i'm at 1.1V at 4.3GHz your voltage is too high, keep bringing it down until it is unstable, then increase it a bit.
August 26, 2012 3:42:03 PM

Did read about OCing and they mention speedstep tech and stuff like that, shall i ignore that OC to 4.2 and set voltage and then ready to go? Instead of doing a deep OC?
August 26, 2012 3:48:52 PM

Edit : I changed voltage to 1.2 and Multiplier to 42, the Idle temps are higher now though, is this normal? or is itc caused by something like speedstep?
CPU-Z Reads 1.192V while core temp says VID: 1.3010 and even 1.3060 randomly?
August 26, 2012 4:01:24 PM

Lol, after the voltage change / GHz, it runs stable no problems, ran prime95 for 30min and temps didn't go over 65...okay good job with auto voltage settings Asus.
It runs at 4.2 now with 1.2 Voltage, i hope it's fine.

you can probably go lower. just keep dropping 0.005 at a time.

see, i run an i5 2500K, paired with Gigabyte Z77M-D3H, i immediately go to the BIOS, and set my multiplier to 42, and turned off my turbo boost... all the others are on auto...

1.2V is ok, as long as u arent going past 4.2 ghz, after going past 4.2 ghz, say, 4.5 ghz, u will need to set the vcore manually..

but, 4.2ghz is fast enough, i ran turbosmooth (best quality) in 3dsmax11, and it's a tangible difference from 3.3 ghz... :) 

so, do i get a best answer?

I didn't disable turbo boost though, apparantly you need it on on Asus boards, will it affect anything negatively? It doesn't go over 4.2GHz,
and sure ^^
August 26, 2012 4:57:56 PM

A negative part is that the idle temps are about 5degrees higher, but 100% load temps are 15degrees less.

thats not how asus boards do it...

August 26, 2012 5:04:02 PM

the way to do it on asus boards is to set the turbo level to the oc you want, and then it'll ramp up to that when loaded.
a b à CPUs
August 26, 2012 5:04:34 PM

the i7 3770K stock speed is 3.5 ghz.. when an application needs more processing power, say, a prime95 running all the workers, it turbo boosts to 3.9 ghz...

so, since you are overclocking it to 4.2 ghz, it is safe to disable turbo boost because you are running higher clock speed anyways...

as for your temperature... it is ok...

i am running a Hyper212 Evo, and OC'ed my i5 2500K to 4.2 Ghz, and i get 62C

not sure whats best tbh, by effecting the turbo level, it probably ramps the voltage more, but you don't have an OC + turbo, which you can end up with elsewhere. 50:50 as which way works best.

auto voltage, set multiplier to 42... stable as a stability ramp...

mine was a simple as set to 43, auto voltage stable, dropped by 0.005V and it was a lot cooler, the auto was a lot more than 0.005V higher, v odd. so much simpler than the old days :) 
August 26, 2012 7:56:27 PM

Okay i'm not sure if it's stable but everytime i run XSplit, and for example press fullscreen of someone when i'm on XSplit it crashes or becomes a black screen, now randomly when running XSplit and watching youtube it crashed but it wasn't a black screen but white/Gray lines, is this overclock failure? Should i raise the voltage or is this meant to happen on crashes and not a blue screen?
August 26, 2012 7:58:14 PM

Edit : It may be my GPU, apparantly HD 7XXX Cards have problems with XSplit program and can cause white lines / Black screen, however how does it look when the CPU crashes? a BSOD?

August 26, 2012 7:59:26 PM

look for whea errors in the event log, they will come before an oc issue
August 26, 2012 8:04:35 PM

Where can i find this event log it wasn't a BSOD, and i believe it was the program because it was always when the program was on even did crash twice in 20min, before that it ran fine for 5hrs.

Can be found here http://www.xsplit.com/forum/viewtopic.php?f=2&t=5058

Apparantly a problem with HD 7000Series, i got 7870 DC2

I disabled speedstep (Do i really need it)

Raised voltage to 1.225

And GHz to 4.3 is this good?

August 26, 2012 8:11:19 PM

speedstep on to keep idle cool, I still voltage is high. Windows event log
August 26, 2012 8:31:44 PM

I will try lower then 1.2 tomorrow, about speedstep alot of people recommend it off, why?

About the crashes, it was XSplit, i confirmed it now, and it also runs at 4.3Ghz pretty good!

August 26, 2012 8:51:03 PM

for extreme oc speedstep off for stability, easier to dial in the oc. but for day to day OC like yours and mine, then on so it idles well.
August 27, 2012 8:39:16 PM

Not sure if my CPU bottlenecks the GPU, but it's never running at 100%, only some times in bf3, it however does rarely drop under 50fps.
Running 4.3GHz at 1.200Volt now for a whole day and stable, should i lower it even further?
