Solved 920 core temps, am I safe?

[GINTER]

OC'd from 2.67 to 4.61, ran all the stress tests, FLAWLESS.

One thing that concerns me is the temperature of the cores under load.
Idle = 45 °C on all 4.
Load = 75 °C on all 4.

Steady, no changes. BTW, never a crash (program, windows), weirdness, or any anomalies.

Thoughts?

75C is too hot for a processor. You should underclock it until your load temp is around 60.

 

[DeaconFrost]

I agree....that is a little on the high side. While it might be stable now, running at that temp for a long period of time could decrease the life of your processor.

 

[pparks1]

Too high, better back that down.

 

[Wishmaster]

My personal opinion is 65C, give or take a couple, at a full load.
And by full load, I mean under a artificial stress, such as Prime.

This means in a real world 100% load, 55-60C will be your MAX.


I too agree, 75C load is too high. Especially for 24/7 use.
I would back it down, or implement a better cooling solution.

 

[paulpicks21]

I agree with wishmaster, I always aim for a max of 65c under full stress test load.

75c is ok if you were just running it at 4.6ghz for benchmarking and stuff.

But for a 24/7 I would imagine 4ghz would get you some nice safe temps.

Cheers

Paul.

Do Not Overclock!

If you want a faster processor, get one.

Overclocking is just asking for problems.

If you want to fight all odds, then at least get yourself a monster-sized cooler for the processor to get the temps down some.

The only thing that is saving you right now is that modern processor will throttle themselves to keep the temps from getting astronomical.

 

[paulpicks21]

I have to disagree with you here Karl, this is after all the overclocking and mod section!

Overclocking if researched and done properly is both fun and safe.

I agree with you on the cooling, but I am pretty sure he already has some good cooling based on his temps at 4.6ghz, he just needs to back it down a bit.

I have run processors for years overclocked without issues.

Please don't take my comments the wrong way, I don't want to start a debate, just defending us overclockers a little

Cheers

Paul.

It would appear that those temps are core readings, since you mention 4 of them. I assume that you are getting those readings from Core Temp, and if so, it gives TjMax for that processor in the gadget GUI. The maximum temperature published by AMD for that processor is 62 degrees Tcase, which should never be exceeded either. If the lifespan of the processor matters to you, then you need a temperature even below that. I would run it at least 20 degrees below either value.

 

[paulpicks21]

The Tjmax for the 920 is around 100c and the Tcase is around 69c

This is in Spanish, but numbers are the same as in English:

AMD Processors for Desktops: AMD Phenom

 

[seekermeister]

Googling, it seems that there are both Intel and AMD 920 processors, so I don't know which he has.

 

[paulpicks21]

Oh boy, I assumed it was an Intel, I guess we won't know til he replies.

I thought it was this - http://ark.intel.com/products/37147

Edit again, will the 920 AMD reach 4.6ghz? I didn't thing AMD were so overclockable? I stand to be corrected as I have absolutely no knowledge of AMD cpu's

 

[GeneO]

66c on Prime95 and 68c on IBT are the limits for me on an Intel I5-760. Expect the 920 should be about the same. 75c is kinda high for an Intel and I think way too high for an AMD.

And if this is an Intel 920, overclocking it by 2 GHz is waaay too much IMO. If you are just doing this occasionally, well OK, but if it is 24x7 I wouldn't go over 1 GHz, personally.

AMD or Intel and what are you using to generate the load?

Have to disagree. As long as you know what your are doing, don't overdo it, and have the right equipment (cooling and motherboard most important), overclocking is fairly easy and risk free. However you need to do your research first.

He said he overclocked from 2.67... he more than likely has the Intel processor.

75C is a tad high, but for that much of an OC that is pretty good temperatures. What voltage is it running at (that will make a big difference as well)? I am assuming this is an i7-920K CPU.

I would also make sure you have adequate cooling for that much of an OC.
I forget what the stock voltage of that CPU is, but you don't want to bump it up past about .2 volts over the stock setting as that could blow the CPU. I would guess that you are way high on voltage.

When you stress test, all you need to do is run Prime95 for over 24hours. No need to do ALL the stress tests, Prime95 for a full day will pretty much guarantee stability.

Nonsense.

...by overclocking.



More like 'Do Not Overclock unprepared'. Or at least like the OP, ask questions along the way.

Overclocking can shorten the lifetime of a processor through the process of electromigration which destroys traces and other features on a chip. Temperature has more of an affect on electromigration than voltage (it depends exponentially on temperature and only quadratically on voltage).

http://en.wikipedia.org/wiki/Electromigration

This is because the temperature loosens the ions in the lattice so that they can be more easily dislodged by the electron current.

You also have to monitor the stability over time. In just over about a year I have had to bump up my VCore a click to remain stable. And that is with a 1 GHz overclock at 65-66c on custom (heavy duty) Prime95 load.

Couldn't disagree more. Back when I built my machine, I got the Q9550 for like $209. It's stock clock is 2.83Ghz. If I wanted to spend $329, I could have gotten the Q9650 which is same chip just running at 3.06Ghz. So, I bought the Q9550 for $209 and then upped it to 3.2Ghz for the first year and a half and 3.4Ghz for the past 6 months and it's been stable as can be. So, I saved over $100 and am running faster with complete stability and no need for extreme cooling.
