3570K Overclock Issues w/ ASRock Extreme4 Z77

post #1 of 32
Thread Starter 
I'm running the following:

3570K (Costa Rica) w/ Hyper 212 Evo (stock fan) + Arctic Silver (pre-coat on heatsink, with line method on CPU)
ASRock Z77 Extreme4
16GB 9-9-9-24 1.5v DDR3 (Gigabyte) 2x 8gb
Sapphire 6870 1gb
750 watt Antec PSU
(6) 120 mm Scythe case fans @ 90CFM w/ exhaust at top and rear, intake on sides and front.


Everything runs flawlessly at stock settings (around 27C idle for CPU)...but my overclocking is having a bit of an issue.

I first followed the guide here:

http://www.overclock.net/t/1198504/complete-overclocking-guide-sandy-bridge-ivy-bridge-asrock-edition


I followed all the directions. With an offset of +0.005, and Load Line of Level 3, I reached 4.3 ghz, but was also was reaching temps of approximately 95C in HW Monitor and RealTemp after 3-4 minutes of Prime 95 with the settings illustrated in that guide. My voltage was reading around 1.224V in CPU-Z.


I immediately stopped the test and started trying to figure out why my temps were so high, and voltage also relatively high.

I adjusted most settings back to stock and just adjusted the multiplier to 43, and started it up again. With all stock settings and multiplier at 43, my voltage was slightly less, but temps still reaching in excess of 90C after only 3-5 minutes of prime95 with the prescribed settings.

To clarify, my temperatures looked like this: Core 1 - 75c Core 2 - 85c Core 3 - 88c Core 4 - 90c


I then decided to set my voltage offset to a negative number and attempt to undervolt the CPU to prevent overheating. I set my voltage offset to -0.060 @ 43 multiplier (4.3 ghz) and immediately BSOD'd. I adjusted down to -0.040 @ 42 multiplier, and it's running stable now at temperatures averaging between 70C-80C max load.


My questions are as follows:


1. Did I miss something? Or are my temps unusually high for my mild overclock?
2. Is there any way for me to properly overclock this 3570k? My 2500k reached 4.5ghz with much lower temps and the same cooler.
3. Should I remove the Hyper 212 evo, remove all thermal paste, and try something other than arctic silver?
4. Are there any other settings I should play around with?


My goal was 4.5 ghz with a max of 80c.




Thanks in advance.

To much thermal paste imo.
Try putting less and reseating and reply back

Probably didnt seat the heatsink correctly, try reseating the heatsink properly you should be fine then.

this issue happened to me before and others who didnt seat their heatsink correctly.

I had a similar issue when I first replaced the thermal past on my rig (it was pre-built). It was as Boyd said, the heat sink wasn't seated well enough. I reseated it, and applied extra pressure, then my temps dropped to the floor.

Do you really think this is a thermal paste issue? I mean my idle temps are around 27C. Or would excess thermal paste or an improperly seated Heatsink only affect the temps at high load?

Also, I'm using AIDA64 right now and only testing CPU Stress Test. My CPU is at 100% load and temperatures are only 65C at absolute MAX.

Does this seem like a Prime95 settings issue???

Well, when I had the heat sink seating issue, I was idling about the same as i was on stock thermal paste. It's worthy to note at this point though, that I was idling at the mid to high 30's c.

As far as the different test, I couldn't say... that is strange. Have you tried the Intel Extreme Tuning Utility yet? If I ever want to check Prime95 against something else, it's usually that. I'd say if IETU does the same thing as Aida, something is wrong with your P95.

I just ran the Intel Extreme Tuning Utility, and after 5 minutes of testing, my temps were bouncing all over the place.

However, the minimum temps under 100% CPU load with Intel Extreme Tuning were 61C and the highest temps were 77C.


So now we have a range to work with.


Prime 95 as per the directions in the guide - 90C average
AIDA64 with CPU test only - 62C average
Intel Tuning Utility CPU only - 70C average


Now I'm even more confused than before.......

OK - so after leaving the PC off all night and turning it on this morning, I have the following IDLE temps as reported by both HWMonitor and Realtemp

31 - 34 - 35 - 32 and a package temp of 40-41. These are idle temps.


At this point, do you all think it would be prudent to remove heatsink, remove all thermal paste with coffee filter + rubbing alcohol, re apply a medium dot of thermal paste on the cpu, re-seat the heatsink, and try again?
post #9 of 32
Yeah, I'd retry, because those idle temps are pretty high for the Evo 212, IMHO.

Go with a very small or tiny dot of thermal past though. In most cases I've seen, less is more in this situation.

I suggest checking out this article on hardwaresecets.com. They try several methods and benchmark them. The results are suprising, especially to people that tend to use more rather than less.

Is the settup you have now using the thermal pad that came on your Evo 212? Either way, if you take off the cooler now, it's best to apply fresh paste.

Let me know hwo it goes!

I am going to give that a shot next week (got a lot coming up so I won't be doing any gaming until then)

As far as the thermal paste,

I used arctic silver 5 as per their recommendations.



1. I cleaned both the heatsink and cpu with rubbing alcohol and a coffee filter.
2. I rubbed arctic silver 5 into the heatsink with a credit card, and removed all excess with a coffee filter so it was "tinted" slightly.
3. I did the "line" method of arctic silver across the cores in a vertical 1mm line of arctic silver 5 (on the cpu)
4. I applied the hyper 212 evo to the cpu, pressing firmly, and tightened all 4 screws with the criss-cross method.


Note:

I did notice that the heatsink did actually slide a bit while I was screwing it in, forcing me to slide it back to the CPU center. Could this have something to do with it? I'm going to re-apply next week and post the findings.


thanks.
