Hello,

I just overclocked a little bit my i7 920 from 2.66 to 3.2GHz, but the thing is that i'm getting temps of 75-80C!

I have it cooled with a Dark Knight HSF and my case is really well ventilated (Airflow is good)

I think I may have put too much arctic silver 5 on the CPU, could that be the main problem?

Thanks!

Putting too much paste could be the problem, but those temps sound extremely high! What program are you using to read your temps?

Download Everest and see if the temps are the same with it:

>> Re: High temps?
that is a nice cooler.

did you increase any voltages to get your 3.6ghz OC ? increasing voltage can and will increase heat output.... when you OC, you want to try to get as much without increasing. You will hit a point where you cant go any further and this is where you need to increase voltage to either be stable or get a few more hz.

>> Re: High temps?
maybe its the voltage... I just left it at [auto] since I dont really understand at what number to start... I know the max and the min voltages supported by the chip, but i dont really know a good number for my OC.

How much voltage should i put into the CPU???

The only voltage I messed with was the DRAM -> 1.64

And im using "SpeedFan" to read temps

Try Everest for temps to make sure Speedfan isn't messed up. No one can really tell you the exact voltages to use for your system, every system is different. On the otherhand, the best way to start overclocking I find is to review some reviews and ask some people with similar configurations and start there. For example, read reviews on the i7-920 to see what they got it up to and at what volts. It will take a while to get it how you want it(fast and stable).

>> Re: High temps?

I assume you've already tried setting the clock/voltage values on all devices back to "normal"?

If you did that and the temp still remained excessively high, then most probably either the chip has been damaged, the heatsink is not properly applied (or something has changed in the cooling subsystem),

If you used one temp monitoring program to check the temps before you overclocked/overvoltaged and are using the SAME program afterwards, then it's likely not the monitoring program that is at issue. But, it never hurts to double-check with an independent resource.

By the way, every system monitoring program I've tried (including speedfan, Everest, MBM, etc) has the potential to mis-identify the temperature reports, sometimes confusing ambient temp sensor for CPU temp sensor, or CPU case sensor v. CPU die sensor(s), and so on. It depends on the system/motherboard. In this case, single-purpose program might be best (e.g. CPU-only monitoring program).

RealTemp Intel CPU Temperature Reporting Program
http://majorgeeks.com/RealTemp_d6098.html
http://www.techpowerup.com/realtemp
License: Freeware
Requires: Win 2000/03/08/XP/Vista/7
"Real Temp is a temperature monitoring program designed for all Intel single Core, Dual Core, Quad Core and Core i7 processors. Each core on these processors has a digital thermal sensor (DTS) that reports temperature data relative to TJMax which is the safe maximum operating core temperature for the CPU. As your CPU heats up, your Distance to TJMax will decrease. If it reaches zero, your processor will start to thermal throttle or slow down so maximizing your distance away from TJMax will help your computer run at full speed and more reliably too."

(I've found RealTemp does NOT appear to support Celerons regardless of claim "all Intel single-core" processors, but of course that doesn't apply here. Just adding the note in case others with Celerons might want to try the program)

(One reason I like freeware versions of RealTemp (and Speedfan) is that AFIK unlike the freeware version of Everest (and some other monitoring programs) these programs allow the user to calibrate the temperature reports. I've found some temps are not accurately consistently reported. Probably the most extreme examples I've found are both a Western Digital and Maxtor harddrive that overreport the actual temperature by 9degC! That makes a big difference when I setup alarms and such. With calibration and entering appropriate offsets I get a more accurate real-time reading in the temperature range most encountered in a given system.)

Um, 2.66 to 3.2GHz is not "a little bit". IMO that's pretty much a whopping huge leap. :)

Ok, I messed a little bit with the voltages, and i got it a little bit more "under control"...

now it full loads at 69-74C and idles at 39-40C, which is much better (and i think i've heard similar numbers)

I used this settings (I hope this helps someone else):

Voltages:
CPU 1.2
PLL 1.8
QPI 1.2
IOH 1.1
IOH PCI 1.5
ICH 1.2
ICH PCI 1.5
DRAM 1.64

I'll try to get voltages a little bit lower

Yeah it takes some real fine tweaking to get optimal settings. It seems to me your temps should be even lower than that though.

If you haven't been doing so, it's a good idea to run extensive CPU and memory tests after changing the settings either up or down...make sure the system is stable at the new settings.

The best way to do it is with a self-booting medium that contains diagnostics so that your OS/data aren't put at risk if something hiccups while running under Windows. Plus, you can test the CPU and memory more thoroughly if Windows isn't running.

2.66 to 3.2Ghz is a fairly light overclock for a Core i7 920.

This should be doable without even increasing voltages at all.

First thing though, take of the CPU cooler, and thoroughly clean the CPU heatspreader & base of the heatsink.

Re-apply thermal paste (only use a little, it will spread itself thin when the cooler is placed on top), and replace the cooler, ensuring it is seated correctly.

One thing I must stress is NEVER leave CPU voltage at 'auto' if you are manually overclocking. The board/BIOS may induce an overly high voltage required for the speed bump.


The standard voltage for an i7 920 is 1.2V (core). You can set it to this manually, then simply increase the bclk (base clock) to achieve your overclock. Most 920's I've seen get to 3.4-3.5Ghz WITHOUT an increase in processor core voltage.

**Edit to add

Also ensure that your CPU fan is set to increase speed as temperature rises, say 60% at 40 degrees C, and 70-80% at 50C.

Also, a quick google turned a great guide from X-Bit labs
http://www.xbitlabs.com/articles/cpu/display/core-i7-920-overclocking.html

Follow what they have done there for your overclock *

* you may or may not achieve the same overclock as they have achieved, but they do at least explain about the voltages / clock speeds that need to be / can be altered to achieve a stable, and safe overclock.

So this would be my first port of call - go into BIOS, and manually set core voltage to default (1.2V), NOT 'auto'.

Ok, I did most of what all of you said,

Ran Prime95 and the only weird thing it said is that it wasnt able to open a file to say "Pass", so everything is fine (ran for about 10 hours)

I left the vcore at 1.2v and I was getting lower temps (still high though). Now, here is my problem:

After the 10 hours of Prime95, my CPU was running at 84C !!!!!

and I KNOW thats way too much...

I will try to reapply the thermal paste, see if thats the problem...

UPDATE: I thought I should update you on my situation, as this could help someone else.

I reapplied my thermal paste according to my type of Heatsink (in my case, HDT kind) with much less grease (yet, very well applied). Also, I lowered the voltage of the CPU from 1.2v to 1.8125 volts (a little bit less than the default value), and now the FULL LOAD temp values are around 70C only. I've been testing the PC for around 20 minutes only, but we will see what happens in the next few hours.

Any other recommendations are trully welcome!

Are you in a very warm environment? What is the temperature in the room that the computer is in? 70c still seems too hot. What is the idle temp?

It is Summer in Chile at the moment, so that could be part of the problem.....depending if his room is conditioned or not.

Well, my room temperature should be around 26-30C, so I don't think its mainly the problem.

I'm getting this readings now:

Full load: 64-70C
Idle: 39-46C

Is it better???

I even "underclocked" the voltage to get this!!! I lowered it from 1.2v (default) to 1.18275 or something like that.

I also reapplies the thermal paste (arctic silver 5) and I'm POSITIVE its well applied. (it seems that was part of the problem before).

Anything else I can change?

What are the temperatures of your other parts in the system? Motherboard, Videocard, Harddrive...etc. They could be making an impact on everything else. How many fans are in your case and what case is it? Which way are the fans blowing? Explain this.

Ok,

Case: Thermaltake Kandalf (4 case fans)
Temps:
-CPU: 36C
-GPU: 63C (GTX 260)
-HDD: 32-35-40C respectively (got 3)
-Mobo: 50C
All this on idle (right after playing a game)

On load, HDD and Mobo dont change much, but CPU goes up to 64-70C, and I havent checked on the GPU, but i'm quite sure its hot as hell also.

Now, about the fans,

The CPU fan is pointing towards the heatsink, and at the same time towards the Extractor fan so the hot air goes outside the case ASAP.
There are 2 HDD fans that bring air inside the case and one fan at the top, intake also.

If theres any more info you need, let me know!

Are you sure you didn't switch the CPU and Mobo temps? Those values would seem inconsistent from what you've reported, especially so soon after stressing the system (playing games).

Otherwise if the Mobo temp is intended to reflect system internal ambient temps, then 50degC is quite high.

The fact that your HDDs are reporting such widely varied readings (8degC !) suggests either one HDD is directly in the path of a high-volume external intake fan, or the drives (like quite a few I've used) need offsets applied to report accurate data. Also keep in mind the temps cannot be lower than room ambient. In your situation, for HDD safety's sake I'd assume they are ALL always running at the highest reported HDD temp. Most HDDs have a operating maximum of 50-60degC. Check your individual HDD specs for details.

But, with your HDDs running that cool, I really doubt your case ventilation is a problem, especially if you did accidently swap the CPU and mobo temps.

If the system hasn't yet achieved "idle" steady-state temps, then all the other temps seem fairly typical to me.

You might consider using a video card control utility to "up" the GPU fan speed a bit more. I don't have a GTX260, but 63degC is not a dangerous temp for most GPUs. However, it doesn't hurt to run as cool as possible.

That's probably right for mobo/cpu temps. Some mobos measure nb/sb and with crappy cooling and crapp airflow those can run at a lot higher temps than the cpu with a big fat hsf slapped on it

EDIT

nvm, yeah if those temps are right after playing a game, than it looks cpu and mobo temps are swapped because kandalf has decent enough airflow for the mobo to stay cool, and there is no way the cpu could drop to 36 degrees that quickly after full loading in a game.
