i5 2500k Overclocking - Page 2

post #11 of 18
Right, well, sorta. It's the measurement of the temp on the IHS (or within a few millimeters of the IHS surface)

"Case"=casing is your clue.

Use HWinfo32 and you'll notice that the CPU temp that you have is significantly lower than the core temps. The CPU temp is the "Tcase temp".
This is NOT the cpu temp shown as "cpu package". It's the cpu temp shown from the motherboard sensor that reads the temp by the IHS. The problem is that this sensor is BIOS calibrated, and I've seen BIOS versions have this temp messed up after updating the BIOS (P5WDH had this happpen after going from 250x to 270x bios version).

This has traditionally been "Tcase", because there was a time when the chips didn't have DTS sensors, and this was the only way to monitor the temps. Also, most standard motherboard monitoring tools monitor the temps directly. Remember, temps are measured by infrared thermometer sensors. The core temps that you get from Realtemp, HWinfo32, etc, are NOT direct temperatures at all. They're diodes INSIDE the CPU that report how far the chip is from Tjunction. and you get the temps with a simple calculation.

You should ask the author of Realtemp how these diodes work, and why they give this measurement, instead of measuring temperatures directly.

okay im getting confused now haha, say for the sake of argument I'm using real temp and core temp to monitor my temps while stressing my baby sandy. Is it safe to say..keep the temps under 85C?

While I believe that temp is within spec, most would suggest you keep it at 70 or below. Preferably in the low 50's, mid 60's. At least that is what I have always shot for when OCing and stressing.

hmm of course lower is always better, but I'm not so sure that temps that low can be had in a 4.8ghz OC unless you're underwater? correct me if I'm wrong. After an hour of Linx I'm at 67C on my venomous x cooler with ****ty 1000rpm fans.

another question is that in LINX under the TIME tab its taking 270 to finish one run...shouldn't that be lower?

also I followed these OC instructions

http://hardforum.com/showthread.php?t=1578110

ran 1 hr of Prime Blend test at 5.0ghz

when I'm not stressing should the CPU be throttling down?

For stress testing and Prime/LinX, try to keep below 85C, yes.
For other daily usage and gaming, try to keep below 75C, and definitely don't exceed 80C, especially when at higher vcores/overclock.

Yes. For stress keep under 85C.

Gaming and stuff like that. Keep under 80C. 75C id better.
