Question for those of you who are more knowledgable than me in this area.

I would like to use everest as my temp gauge for my overclocking. (its the only one that I can seem to get to run on vista 64bit the correct way).

the question that I have is which tempature should I really be paying attention too, the core 0 core 1 temps or the cpu temp.

currently with no OC on my X6800 with stock HSF my numbers are 34 for mobo, 36 cpu, 55 core 0, and 53 core1 with minimal load.

So the X6800 can go to 64.5ºC which temp should i be going off of?

according to http://www.hardwaresecrets.com/article/143/5




thanks for any help you all can give me.

I would download and use the latest version of "coretemp" for checking cpu temperatures. Then read the sticky on core2 temperatures. I would use everest to check other temp: mb, gpu etc.

dragonflyrx, please read the Sticky at the top of this Forum.

You are confusing CPU temperature (Tcase) with Core temperatures (Tjunction). Also, you have mistakenly mis-read the specifications for the X6800, which is Tcase Max 60.5c. You have instead posted the specifications for the Quad Core QX6800 G0 Stepping, which is Tcase Max 64.5c.

Additionally, your Tcase (36c) to Tjunction (55c hottest Core) Delta (19c) is inaccurate. The Delta should be 15c +/- 3c. Since you posted temperatrures with a Tcase to Tjunction Delta of 19c, this typically indicates that Tcase is not correct due to inaccurate BIOS thermal algorithms. This can be sometimes be corrected by a BIOS update. Regardless, SpeedFan 4.33 is the preferred temperature monitoring utility, so if it will run on your Vista rig, it will allow for temperature offset corrections to be configured. Section 9 in the Temperature Guide will show you how to properly test and accurately calibrate your temperatures, so you'll know that they're correct.

The answer to your question is that both temperatures are important. From the Temperature Guide:

Section 6: Scale

If temperatures increase beyond Hot Scale, then ~ 5c below Tjunction Max, Throttling is activated. The Digital Thermal Sensors (DTS) are used to trigger Intel`s TM1 and TM2 technologies for frequency, multiplier and Vcore Throttling within individual Cores. If Core temperatures increase further to Tjunction Max, then Shutdown occurs. Since Tcase indicates CPU Die temperature only, it is not used for Throttle or Shutdown activation, however, referring to the CPU`s shown below under Scale 1 as examples, Tjunction Throttle temperature is ~ 95c, so Tcase would be ~ 85c, which would far exceed Tcase Max. As Tcase to Tjunction Deltas are constant, Tcase Max is always the limiting specification for temperatures.

Scale 1: Duo
E4x00: Tcase Max 73c, M0 Stepping, Tjunction Max 100c, Vcore Default 1.325, TDP 65w, Delta 10c
E2xx0: Tcase Max 73c, M0 Stepping, Tjunction Max 100c, Vcore Default 1.312, TDP 65w, Delta 10c
E6x50: Tcase Max 72c, G0 Stepping, Tjunction Max 100c, Vcore Default 1.350, TDP 65w, Delta 10c
E6540: Tcase Max 72c, G0 Stepping, Tjunction Max 100c, Vcore Default 1.350, TDP 65w, Delta 10c

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

The following Scale applies to your X6800, which is B2 Stepping:

Scale 5: Duo
E6x00: Tcase Max 61c, L2 Stepping, Tjunction Max 100c, Vcore Default 1.325, TDP 65w, Delta 15c
E4x00: Tcase Max 61c, L2 Stepping, Tjunction Max 100c, Vcore Default 1.325, TDP 65w, Delta 15c
E21x0: Tcase Max 61c, L2 Stepping, Tjunction Max 100c, Vcore Default 1.312, TDP 65w, Delta 15c
X6800: Tcase Max 60c, B2 Stepping, Tjunction Max 85c, Vcore Default 1.3525, TDP 75w, Delta 15c
E6x00: Tcase Max 60c, B2 Stepping, Tjunction Max 85c, Vcore Default 1.3525, TDP 65w, Delta 15c
E6x20: Tcase Max 60c, B2 Stepping, Tjunction Max 85c, Vcore Default 1.3525, TDP 65w, Delta 15c

-Tcase/Tjunction-
--60--/--75--75-- Hot
--55--/--70--70-- Warm
--50--/--65--65-- Safe
--25--/--40--40-- Cool

thanks a ton I guess i'll have to be doin a little more research on how to get speedfan operating on my computer.

thansk again.
