Large temp jump when OC'd

[CheesePoofs]

Finally found some free time and I was able to start overclocking my winie 3000.

My max HT is >300mhz, right now I'm at 9*270=2430mhz.
Vcore is set to 1.525. CPU-Z reads it as 1.472, bios said 1.5 IIRC.

Normally I'm not worried about temps, but with this OCing I got large temp jumps. Idle temps didn't really change, but my load temps went from 38-39 to 47-48. My board reads temps very low, but that seems like a pretty large jump to me, is it OK?

Fine and very normal IMHO. My load temps at 2.6ghz are 52-54c, been running it this way for 3 mos with no problems. The point where the chip shuts down due to temp seems to be 70c from peoples experience, so anything under 60c is OK IMHO

Nice O/C by the way:thumbsup: you gotta luv these winnies. Now if I can just get a date with her sister Venice

Its not the temps I'm worried about exactly, its the large difference between the temps before and after my overclock. I don't trust my board's temps at all though, when I first got it it said my chip idled at 25C.

I think thats pretty common too. It must take awhile for the diode to start reading properly or something. I remember when I first set my board up mine was showing unrealistically low temps for the first week or so, like 25c idle 30c load. But a diff of 10-14c change from idle to load is normal with a good overclock on air

I must not be wording this correctly ... I'll try again

The thing that suprised me was the difference between my load temps at stock speeds and at the new overclocked speeds.
Stock load temps:............................ 38-39C
overclocked load temps: ................ 47-48C
Difference .......................................... 9C
That seemed like a big difference to me, and it made me a bit nervous.

EDIT: BTW, I'm on the stock HSF.

The temperature differential doesn't mean much. All you should be concerned about are the actual temperature levels. Jumping from, say, 40 to 50C is okay, but going from 50 to 60 is not so good.

Bottom line is that, if you boost vcore, you will get higher temperatures, but if you're in a safe temperature range, it's okay.

If you're really worried, just back your OC off a bit until you can figure out how far off your board's temperature readings really are.

My load temps @stock were 36C and when I pushed the vcore to 1.52V (as read by cpu-z) they jumped to 43C. Sounds like you're just fine, especially since you're using stock cooling

And there lies the answer!!! The worse the HSF in terms of c/watt ratio will have bigger swings from idle to load.....As you OC you are increasing the watts of heat and thus you are starting to gain more in the laod swing. A highe end HSF as a much lower C/watts ratio and thus doesn't swings as much even as vcore increase and watts of heat increase...

Those tem,ps look fine...Run S&M 1.5 for 90 minutes (about length of test) and if it doesn't crash from heat then your numbers are pretty safe. S&M 1.5 will get you to hit highest temps you likley have or will ever see. I have yet to be able to duplicate it with any real world app....

The problem, lies in the fact the stock HSF is all aluminum and many of the mid to high end hsf have copper cores and/or all all copper...have a better coefficient.....Then throw in the fact the retail HSF has a less powerful and high cfm fan. AMD is trying to stick in a ceratin audible (dB) area so many of the mid to high end hsf will have better airflow with increase size (Ie 92-120) and even in some cases increased depth of fan....


IN the end tose temps are pretty nice even if reported low...heck most are reporting wrong. In terms of piece of mind I would be satisfied...push ahead and less stability tell you if temps are really too high or too low...
