Tried manual OC @ 4.2 Ghz and played Crysis3 for about 45 mins and got these temperatures for the CPU and two GPUs as indicated at the "Max" column. Out of the game, both the CPU and GPUs idles at low 30Cs. Are the temperatures within safe limits?



I have to add that only Crysis 3 raises the temperatures, other games the temperature are much lower and present no issues.

Looks fine. It is a GTX780 and an overclocked 4770K after all.

These temps are well within limits

Factory overclock hardly increases temp or perf

TS ur load temps are just a wee bit high even for noctua
u can aim for overall 70degC

r u using offset method or fixed manual voltage method? offset will be better

Thanks for yr advice bro. Yes using fixed Manual method, wwill change it to Offset method instead.

Bro i changed to 'Offset' but got BSOD & crashes so i set it back to 'Manual' mode. I played Crysis3 for 45 mins again but found the temperatures lowered irregardless, perhaps due to lower ambient temperature or i don't know why but just glad they're nearer to 70C as you recommended. Thanks bro & Cheers! :D

for long term use definitely have to put on offset bro

since it crash at that voltage try up slightly by 0.10 or 0.15 until stable

OK thanks i'll try up the voltage a bit. You mean if i use 'Manual' mode it will damage the CPU?

wont say damage but will shorten your lifespan. because its taking in max voltage all the time no step up or down. in the first place overvolting it already shortens lifespan u wanna put it on that voltage permanently somemore abit... you know

EDITED :
Up voltage to 1.210 got BSOD when reached Win boot screen, now at 1.220 can boot to desktop but will test stability - also crashed :( Btw I'm using air-cooling, is it safe to use voltage above 1.200v? Bro under AI Overclock Tuner, can i use the 'Manual' setting? Or have to use 'Auto' instead? Pardon my noobness :(

im using 2600k Sandybridge (SB i.e. lga 1155)

from what i understand, the main idea is:

step 1. decide on the multiplier (for me its 40x to reach 4ghz)

step 2. decide if its for "all cores" or for "per core" (for me, its for all cores)

step 3. select LLC as middle (3/5 for asrock mobo, 5 or 6 /10 for asus mobo) why middle is just a rough gauge, u dont want too much or too little for now, anyway LLC can come back to tweak later. (btw u shld understand that LLC is to counter the effect of vdroop)

step 4. select manual voltage mode, set a suitably low vcore voltage (for SB @4ghz can try 1.2v), reboot, if cannot reboot then set abit higher until can reboot

step 5. stress test, if bsod, then go back to step 4 and set abit higher vcore. if no bsod, then during stress test, note down the vcore value shown in cpuz under 100% load, and at the same time note down the VID value shown in realtemp under 100% load [click on the realtime running stopwatch icon in realtemp until it shows VID]. the difference between vcore and VID is the offset. from what i have gathered, generally for SB, below 4.5ghz, the offset is negative i.e. for example the chip wants 1.24v as VID but i supply it with only 1.2v as vcore so the offset is minus0.04v

step 6. now u have a rough idea what the offset should be. note that its just a rough value, not the optimal one yet. now, go into bios, switch to offset mode, then dial in this offset value, then reboot and stress test again, during stress test, note down the vcore (not VID). this vcore value during stress test should be near the vcore u arrived at, by the time u reach step 5.

there are many other parameters to fine tune. for eg. i enable speedstep, enable EIST C1, but disable c3, c6 deep sleep states, enable PLL, keep ram timings at auto, etc. u need to slowly n gradually tweak until no bsod, low enough vcore, load temps low enuf, all at the overclocked speed u target at. for SB, 4to4.4ghz, vcore shld not exceed 1.25v, for 4.5 or 4.6ghz, vcore shld not exceed 1.35v, etc etc these are just approx guideline values, actual performance really depends on ur chip and the quality of all ur other components mobo, psu, cooling, etc unfortunately i am not sure of what the guideline vcore values are for haswell lol u got to slowly google for the relevant info
and TS i strongly suggest u go back to 4ghz first, nail down everything before jumping back to 4.2ghz, no offence, just suggesting a slow but steady approach gd luck also if anyone can spot any mistake i made, pls kindly correct me, im also learning as well lol :)

Bro i am truly humbled :o Thank you very much for the comprehensive explanation!! Will save it for my reference. I have to tell you that you lost me somewhere about 1/3 into the text :D Anyways as a last resort, i reverted to "Load optimal defaults" at BIOS which brought the target CPU speed to 3.9 Ghz (i believe its tied to the Turbo boost speed) which is already close to the 4 Ghz you suggested i start with :D So the next best thing i could find is Asus' automated OC profiles of 4.2, 4.4 and 4.6 Ghz using Asus' AI Suite III software. Not being a greedy arse i chose the most conservative 4.2 Ghz and just played an hour of Crysis 3 with CPU and GPU temperatures hovering at around low 70Cs and just just below 80C respectively :s12: If it stays stable at this OC speed, then all's well that ends well wish me luck!!

no problem bro but personally i would be skeptical of any "automated overclocking profile" thats preset by any manufacturer. kinda reminds me of the MSI their "OC genie" button thingy. the main concern with these kind of manufacturer preset profiles is that they may supply either a tad too much voltage, or the voltage may be erratic or nonconsistent.

give u a maths analogy to overclocking: its similar to solving implicit multivariable equations :s13:.
for example, solve this, i.e. find a solution set, for four real-valued variables x1,x2,x3,x4:

[88(x3)+[cosh(72log(x1+arcsinx4)]^(x2)]=[e^(x1)]/[x4.x2+256]

u can punch this into matlab and see if it returns you a real-valued solution set. and suppose, somehow, you know, either by your own empirical discovery, or by the manufacturer's specifications, that the overclocking characteristic of your diy pc is governed by that weird equation, and that the variables x1,x2,x3,x4 represent multiplier, offset, vcore, load temp. now if u dump this into matlab, it may offer you a few different solution sets. these will represent different overclocking profiles.
but end of the day which profile suits your need?

and in the real world, u dont even know what the governing equation is or maybe it doesnt event exist LOL. but even if it does, u still dont know what the governing equation is, and so can't even use matlab to help u get solution sets. which means u got to iteratively and manually try different values of x1,x2,x3,x4 again and again in iterative cycles until they converge (remember newton-raphson iteration method?) towards something that roughly works ok. ie. manually tweak until u empirically obtain a workable profile, which, usually, i sense, can be better than those manufacturer supplied profiles.
have fun =)

Thanks bro, man you're a true OC guru Salute! Yes I had an MSI board the last time, the OC Genie was real crap, felt so cheated. It was then that I learnt to do manual OC with the help of guys at the MSI Forums - pretty straitfwd - they gave me a set of settings, then ask me lower this/that until its stable when doing stability tests, and it worked out in the end. But I know manual OC is a tedious process of trial & error followed by repeated torture stability testing, there is no short cuts. Frankly speaking I'm abit reluctant to do so again, but perhaps when I have the time and mood i'll get my hands dirty again. I was quite surprised that even at its stock default settings with Turbo boost it runs at 3.9 Ghz constantly when the situation calls for it. The 4.2 Ghz automated OC runs quite stable so far in that I was able to play Crysis3 at temperatures of 71-73C for an hour or so, fingers crossed... To its credit, Asus' AI Suite III OC software is much more reliable than MSI's OC Genie in the past (don't know about now) which can't even last a few minutes past the Windows desktop screen, don't talk about gaming for an hour. Thanks again bro!

Thanks for sharing bro. Wow u can run at 4.2Ghz on a stock cooler? I use 1.20v when I tried manual OC, it actually ran stable no crash. Only after I change from 'Manual' to 'Offset' mode that it crashed, even after upping 0.10v incrementally doesn't help :( Thats why I reverted to automated OC for now.

My current temps at idle is around 31-32C and max of 80C at load quite similar to yours. I always did the IBT at maximum though but for this round I used Aida64 instead and it ran for about 12 hours no problem. But don't know why games still crash :( I reformatted and reinstalled OS recently so I will run more tests see how.

Thanks bro. So strange it idles at 63C? You using stock cooler? Yeah I remember the last time my 'leave blower' ATI HD4870X2 can shoot temps to 98C when playing Crysis until PC locks up and reboots. What I don't understand that despite the auto/manual OCs, CPU temps were never an issue, but still can crash... My GPUs usually idles at low 40Cs, just that I have 2x 120mm fans blowing directly at them that's why their temp can be so low (31-32C) at idle.
