4770k OC / delid needed?

[ieatm3s]

Here is the thing. I set the voltage to 1.2 and started to OC with 100 MHz increments. Already at 4.0 GHZ and 1.2V my chip gets to 100 *C within 5 minutes of running Prime large FFT test. My cooling solution is a Dark rock pro 2 at 100%. I heard about haswells being hot but this is just crazy. How do I check if my CPU is even a good overclocker if I cant push it past 4.0 without it throttling ? I would not consider Deliding if my chip was a bad overclocker. 

 

Thanks for the advice!

I can put my CPU to1.4v without overheating. While I'm watercooling, your temps are very high. I think there is something wrong with your cooler. The dark rock 3 gets to 68c with 1.4v according to linus' latest video.

I can do 1,3V on my Dark Rock Pro 2 in order to get 100 *C (1,3V 4,5GHz stable, 1,165V 4,4GHz stable max temp 78-82 *C). I would say that deliding yours would help. Since I need to give a lot of voltage to mine if I want to go from 4,4GHz to 4,5GHz then I know that mine is bad overclocker. Yours may be average/good overclocker but it looks like that changing thermal compount under heat sink of your CPU would help a lot. (It is a big risj though).

Try remounting your cooler and using some better thermal paste such as MX4

The problem is you're using the wrong program, it's been said over and over again. Don't use prime 95 on Haswell chips... use Aida64! prime95 draws too much voltage causing over heating issues..

 

Try that first, if the heat issue is still bad then you can look at doing something to the hardware.

[i_build_nanosuits]

DO NOT USE PRIME95 to stress test haswell CPU's i'd suggest you use intel extreme tunning utility, prime95 will damage your chip.

 

Your could use Aida or OCCT but if you use one of those make sure you are set to MANUAL voltages. but intel XTU is nice and it's pretty much the only program that acurately monitor voltages and it can test RAM and CPU separetly and it won't apply any additional voltages even if you use adaptatiuve voltage settings.

Wow, thanks for the fast replies guys! I remounted the cooler with fresh MX-4 paste (same as before). Last time thermal paste was applied was December.

 

I did not know using Prime95 was bad for the chip. I figured it is the go-to stress testing tool since way back. For the lulz I ran Prime for the first 5 minutes and temps went only up to 80 *C ! Right now I am running Aida64 benchmark and temps are 60-70 *C.

 

Now I will try to increase frequencies in 100MHz increments until I hit a wall at 1.3 V, after which I will increase voltage if needed. Question: After I find a stable frequency I should change voltage from manual to adaptive, correct?

i think its 1.3v but correct me if im wrong

[ieatm3s]

Errr, 1.3 V, Correct.

Correct, here is a good overclocking guide for you to follow:

http://linustechtips.com/main/topic/41234-intel-haswell-4670k-4770k-overclocking-guide/

 

As you can see in the thread here are the settings to change AFTER you've found your stable OC, that will put the CPU in powersaving modes when idling and will save on power and heat and prolong the lifespan of your chip (adaptative voltages and frequencies)

 

Haswell Low Power Modes

 

    •Make sure you are on the latest official Bios!

•Cpu ratio mode- Dynamic

•Enhanced Turbo- Enabled

•CPU core voltage mode- Adaptive

•CPU ring voltage mode- Adaptive

•Intel C-state – Enabled

•C1E Support- Enabled

•Package C-state limit - Auto

 

for windows users also make sure you set your minimum processor state to 5%

 

Windows7

 

->Control Panel\All Control Panel Items\Power Options\Edit Plan Settings

 

-->Change Advanced Power settings

 

--->Processor Power Management

 

---->Minimmum Processor state

 

-on battery 5%

 

-plugged in 5%

Looks like 4.3 is the limit. at 4.4 it isn't stable with 1.3 V and is pushing into the 90+ *C range. Thanks for the help guys.

we have the same quality chip, mine run at 4.3ghz with only 1.19v but for 4.4 i need to push more than 1.29v for stability...not worth it!

[ieatm3s]

Mine needs 1.275 for 4.3 and currently I am testing 4.4 with 1.32V, temps seem to have dropped for another 6 *C from yesterday. Id be thrilled with 4.4 at 1.29

and you need that kind of performance for...?! hehe

DON'T USE PRIME 95

 

You may have gotten a bad overclocker, but i would advise against deliding. It is very easy to destroy your cpu especially on haswell's because of the extra components under the heat spreader. My advice is to be patient with your cpu when overclocking. It took me a week of tweaking and fine tuning to get my 4670k to 4.6ghz at 1.3v

Prime95 is perfectly fine for testing stability provided you aren't using adaptive voltage. At 1.25v on my 4770k on air it rarely gets above 85c which is of course quite hot but not damaging. Be sure to use Small FFTs if you're going to use prime though. If you want a less synthetic and more real world stability test though check out RealBench 2.2 stress test. If you can pass 4-8 hours on that you should be good to go. I would also suggest that if you can get a stable 4.2 at less than 1.25 24/7 go with that over a 4.4 at 1.30. Not enough performance gain to justify the increased voltage and heat. I currently run at 4.0 24/7 on mine because I can do it at 1.17 whereas its almost 1.26 for me to get 4.2 and even that I'm not sure because I gave up after hours of tweaking trying to get it stable.

 Funny you should mention to use small fft.When I was testing with prime, I did use small fft and was perfectly stable, however after I went to test large fft my pc crashed after 15 minutes. I tuned it now using aida64 and is perfectly stable now at 4.3.

BUT BUT BUT you told me to use prime 95 before? IS MY CHIP BREAKING?
