My i5 2500k temps are all over the place.

[NikolaeVarius]

I got a new i5 the other day and tried my luck at Oc'ing.

I'm on the stock cooler and it was idling at about 34-37 degrees C.

However, on Prime95, it went up to about 98 max. (Holy shit). While gaming it hit about 80 degrees. I'm fairly sure it shouldn't be approaching anywhere near those temps.

Is the stock cooler simply not enough to run this thing at 4.4 ghz? It's at a vcore of 1.125

I think you answered your own question. What case do you have?

 

[NikolaeVarius]

Antech 300. I'm sure the air flow isn't the problem.

The ATOT review also mentions it easily getting to 4.4 on stock cooling.
Further more, even at 4.4 I actually haven't encountered any problems while playing games. Isn't the CPU supposed to crash when operating at 85 or so for several hours at a time while playing games?

1.125 volts? Nice chip.

1.125 at 4.4? um you sure about that?

either way its pretty silly to run the cpu at 4.4 with the stock cooler. what made you think that was a good idea in the first place? and those temps are probably about right considering what you are doing...

Mostly the i5 review

"These chips overclock very well. Both my Core i5-2500K and Core i7-2600K hit ~4.4GHz, fully stable, using the stock low-profile cooler."

and you said yours was stable but that does not mean your temps are not going to go through the roof. if you want to oc then spend 25 bucks and get you decent cooler. otherwise you are just going to be running your cpu at high temps and increasing the chances of it overheating.

stock cooler running at 4.2ghz causes my i5 2500k to go high (70C or higher)

suggest you to get a 3rd party cooler

I see.

I still find it incredibly insane that the CPU runs stable at such high temperatures.

would you have been happier if you had destroyed your chip during this little experiment?

and I still cant believe that you are at only 1.125 for 4.4. are you sure that is load voltage?

 

[Schmide]

are you sure that is load voltage?

This. No way that 1.125 is load voltage.

Get some better cooling or get ready for a new chip.

I'm sure it would be fine if the vcore was really 1.125...

If vcore is on auto in the BIOS, then at 4.4g it's most likely 1.5 or more..

If it really is 1.125, then I suggest you contact the Vatican ..:biggrin:

 

[Smartazz]

I also doubt that you're at 1.125v at 4.4GHz. Make sure you aren't set to auto voltage. It set my voltage to 1.3v at 3.6GHz when I got it rock solid stable at 1.12v. I knew auto over compensates, but I didn't realize it overcompensated that much.

I think the Tmax is listed at like 98C....that would be the point of throttling I believe....so I am not surprised it was chugging along. Not good for it by any means though....

I'll take the trouble to comment . . . I see all kinds of things going on with this thread . . .

The OP didn't say "how" he was over-clocking. Didn't mention whether he'd tweaked the "offset" or "extra-voltage-in-Turbo," or simply used a mobo-specific "auto-overclocking" procedure.

Some BIOS' have initial biases in their reading of temperature sensors.

Some different temperature-monitoring programs have quirks and differences.

And I'd also say that the temperatures he cited even seem high for 4.4Ghz, stock cooler, etc.)

Initially, I'd go back to stock settings. I'd update the BIOS, noting any difference in temperatures reported by BIOS. I'd compare the motherboard's own Windows temperature monitor with something like HWMonitor or CoreTemp (what have you . . . ).

If you stress-test with PRIME95 or LinX (or IBT) -- watch the voltage monitor reading just before and after you terminate the stress-test. If the highest value exceeds 1.35V, try for a slightly under-clocked and under-volted stable stress-test.

There are threads and posts all over this particular forum about tuning "Auto" VCORE with "Offset" and other voltage options. You can fine-tune your settings if you are willing to live through the usual failures and difficulties . . .
