I've tried getting my 2600k to 4.8ghz, but my chip just can't take the heat. I see people getting 4.8ghz and even 5ghz with temps that are below 70C. With mine at 4.8ghz, no matter which bios settings I use and how many times I reseat my nh-d14 heatsink, I'm pushing 80-89C.

I'm thinking that it's just the chip that I have, might not perform as well as other batches out there because I've seriously tried everything. So, I'm thinking of backing it down to 4.6ghz. Is there really THAT much of a difference between 4.6/4.8/5ghz? I wouldn't think so, so 4.6 may allow for better temps and a more stable system.

Go with the lower clock and a more stable system. Anything above 80C is going to seriously hurt your chip. It doesn't matter how much of a difference the clocks make, frankly, because your chip will be dead if you keep running it that hot.

Now that it is completely irrelevant, clock speeds only make a huge difference in things that aren't gaming, for the most part. If you're video/audio rendering or folding, higher clocks make a difference for sure. If you're primarily gaming, the difference between 4.6 and 5GHz is very small.

For folding work there would be a substancial difference in time per frame (TPF) between 4.6 and 5.0. I cannot really thing of another job the processor would be called upon to do (video work at 5.0?) that would matter. What job do you want to do with your processor at 5.0? There are routes to take when you reach these walls and yours is better cooling,that is if reaching a stable 5.0 simply must happen.I think it is great not to blue screen right out of the gate at 5.0 but I am sure you are after more than that.

I do HD video work. In after effects it takes about 20 minutes to render about a minute of video depending on settings, so that's why I need an overclock. But... At this point I'm thinking it's just seriously the chip that I got, there's no way after reseating this NH-D14 10 times, reapplying the paste, taking off the sides of the case, gutting everything inside of it, putting it in front of an air conditioner, and trying every bios combo imaginable that I'm not getting lower temps than 80-90C at 4.8ghz.

I look at other people's overclock and they're getting 30C lower temps than I am, sometimes even with a cooler that's not as good as the Noctua. I could RMA the cpu but I'm not sure how they'd feel about that since I actually had to return some ram already. But yeah, I seriously doubt it's something I'm doing wrong. Maybe I'll try and RMA it...

PS: At completely stock settings, I'm getting nearly 60C load. Surely it should be better than that with my setup, no?

I have the same issue with an i7-2600K and a Corsair H60. I crank up the clock and the heat goes up up up compared to others with the same combo. I have taken the block off. Redone the thermal compound. Tried different brand. Cleaned it all off. and on and on and on... Still nothing. Either the cooler or the chip is not great. I am going to RMA the cooler and see.

It sucks because, for what I use the computer for I can't tell the difference between this i7-2600K and a Dell T7500; dual x5680; 96gb ram, etc. So I'd really like to get $8k or so for my T7500 and use the 2600K.. but I can't get it to stay stable ;-(

I'm about to RMA the chip. We'll see once a new one comes... Actually, I'd like to RMA the heat sink too, but I don't think anything's wrong with it. It locks down perfectly and is solid.

 

[Thared33]

I just ran a test with the stock cooler for the first time. I was getting in the high 50s at stock speed with the Noctua, and the stock heatsink is giving me near 70. So the Noctua is DEFINITELY not the problem...

But one thing I did notice is that this stock heatsink is difficult to lock down. It seems wobbly and if you press on one side of it it'll wobble over. Doesn't seem stable. Even with those little twisty things - after twisting them it didn't seem to lock them down much. Hmm...

 

[Thared33]

Alright, I locked down the heatsink as best I could, still same problem. I already RMA'd the chip, going to see if a new one helps.

Another question: can my ASRock mobo actually be the culprit in getting the temps so high?

Last thing you want to mention to an Intel tech is that your chip runs hot with an overclock, or at least I will say I got a pretty good grilling on if I overclocked when I did an RMA on an i7-920 about a year ago. The way to handle an RMA with Intel is to play it as if you were the most straight laced but technicaly competent customer in the world.They want to see if you can perform normal low level troubleshooting steps,if you come across as too smart they get suspicious.

^it's a K series chip. it was marketed with overclocking in mind, has price premium for overclocking so i hope intel supports isn't f-ing this up.

if you want 4.8 GHz or above you most likely will need a custom watercooling loop.
what is your voltages at your clocks?

btw running the CPU at higher than 80 C is considered dangerous and it can seriously impact the lifespan and stability of the chip. personally i never run any of my intel CPU above 70 C. as a general rule of thumb, keep 20 C below Tjunction, which is 99 C for this cpu.

as for the difference between the clocks, the program you use has to max out the CPU 100% in order for there to be any difference. is after effects completely maxing out your CPU when rendering? sometimes the hard drive can bottleneck the CPU in large data transfers. what about your GPU? i heard it can help in video editing also.

I ran into this article while looking at a different subject. It is a bit old (from 2008) but does give a bit of insight into Intels mindset when it comes to chip life (and what affects it) and why warranty is how it is (or at least was for the day the article was written). A bit of debate on overclocking in general and what this one paticular writer says you should expect.

OK guys, I tried the original heatsink/fan combo and at completely stock settings I was still getting 80C plus on the CPU. There's absolutely no way that I was seating this wrong, I tried a million times with both heat sinks.

I just RMA'd the processor. I'll give an update in the next week or so once my new cpu gets here. Let's hope that this will fix the problem.
