Is 43 C idle temp OK for overclocked E6850?

I've overclocked my E6850 from 3.0 to 3.6ghz and it's running stable. VCore is at 1.35 (default is 1.325).

It idles at approximately 43C according to bios (system temp is 39). I'm not sure what it is under load.



Is that OK?

worry about the loaded temps no higher then 70c

Read the OCing guide over in the Overclocking section for programs. Core Temp Beta reads the cores correctly. Prime95v255 will load them up nicely and check for stability.

ericvpi, the following specifications and Scale for your E6850 is from the Core 2 Quad and Duo Temperature Guide http://www.tomshardware.com/forum/ [...] ture-guide

E6x50: Tcase Max 72c, G0 Stepping, Tjunction Max 100c, Vcore Max 1.350, TDP 65w, Delta 10c

-Tcase/Tjunction-
--70--/--80--80-- Hot
--65--/--75--75-- Warm
--60--/--70--70-- Safe
--25--/--35--35-- Cool

If you'd like to understand your temperatures and learn how to test, calibrate and properly monitor your rig, then check out the Guide. It also contains links to all the software you'll need.

itotallybelieveyou, when making recommendations regarding temperatures, it's important to be specific. 70c can be HOT or it can be SAFE, depending upon which temperature and processor you're referring to. Since there's a 10c or 15c difference between Tcase (CPU temperature) and Tjunction (Core temperatures), and up to an 18c difference in temperature specifications between certain processors, users can easily misunderstand which temperature is which.

This continues to be a major source of confusion within the temperature community, especially for users who are struggling with their first build. If we're not clear, then the temperature topic is reduced to a bowl of apples and oranges thermal fruit salad. I've been working very hard to help users make sense out of temperatures, and everyone can help just by being clear and specific when making recommendations. If your not sure which temperatures apply to which processors, then just refer to the Temperature Guide. Most of you regulars here on Tom's Forums know that it's located right next to Graysky's Overclocking Guide.

Thanks,

EricVPI, the specifications shown above are from Intel, and correspond to your processor, so your overvolt is a relatively insignificant increase. Prime95 in-place Large FFT's max heat is misleading, because it refers to total heat disipation between CPU and memory. Small FFT's, which is used for stress and stability testing, will produce processor temperatures about 4c higher. You may want to re-test using Small FFT's.

Also, you haven't mentioned which temperature your referring to; CPU or hottest Core? As I explained above, it can make an important difference.

not really. I think anything under 1.5V is safe. Define your "small load" 50% or 20%

yup 63c should be fine

Um, according to CPU Z on the main screen it says 1.312v.

Oh, btw, I'm using DDR 800 RAM. Should I get some DDR 1066 for better performance? I have my RAM multiplier set to 2x at 800mhz, if i try to take it to 1066 it will crash.

Also not sure if I should touch FSB voltage.

DDR2 800 is fine. You won't notice the difference at 1066. 3.6Ghz at 1.3875 Vcore, 63c hottest Core with 23c ambient is excellent! You're in great shape. Enjoy your rig!
