I read the sticky on temps but...

I am overclocking an E8500 3.16, Wolfdale
with 8gb of OCZ Reaper HPC DDR2 1066 (PC2 8500) 5.5.5.18
GA-EP45-UD3P

it is currently over clocked to a 3.80
at 1.28 V
bus of 400MHz
FSB of 1600
multiplier of 9x

according to CPU-Z

Under a full load running prime it reaches 72 c
According to Intel 74 c is ok for a max temp
I will never work this computer this hard for any length of time.
It would seem that this is an ok temp

Is it?
what is the max it can run under this heavy of a load?
Just an idea I know each processor will very.

Jesus... my E8500 never breaks 50 under full load at 3.8 GIghz. **** it never broke 60 at 4.2 Gighz. you really need an aftermarket cooler because 72 is hot and will only get hotter once u add a gpu pumping heat into your case as well.

frenchsquare,

But ... what? Not easy enough? OK then ...

What CPU Stepping?
What CPU cooler?
What ambient?
Which 72c? CPU temperature or Core temperature?
Which temperature monitoring utility?
Which Prime95? Large FFT's or Small FFT's or Blend?
For what duration?
Case covers installed or removed?
All fans at 100% RPM?

There is no "Easy Button", and one size does not fit all! If you want an accurate answer, then it''s important to be specific, because guess what? The topics of processor temperatures and overclocking are all about specifications!

From the Guide:

Section 6: Scale

Scale 1: Duo
E8x00: Tcase Max 74c, Stepping E0, TDP 65W, Idle 8W<--E8500 E0
E7x00: Tcase Max 74c, Stepping M0,TDP 65W, Idle 8W
E5300: Tcase Max 74c, Stepping R0,TDP 65W, Idle 8W
E5200: Tcase Max 74c, Stepping M0,TDP 65W, Idle 8W
E4700: Tcase Max 73c, Stepping G0, TDP 65W, Idle 8W
E4x00: Tcase Max 73c, Stepping M0, TDP 65W, Idle 8W
E2xx0: Tcase Max 73c, Stepping M0, TDP 65W, Idle 8W
E8600: Tcase Max 72c, Stepping E0, TDP 65W, Idle 8W
E8xx0: Tcase Max 72c, Stepping C0, TDP 65W, Idle 8W<--E8500 C0
E6x50: Tcase Max 72c, Stepping G0, TDP 65W, Idle 8W
E6540: Tcase Max 72c, Stepping G0, TDP 65W, Idle 8W

-Tcase/Tjunction-
--70--/--75--75-- Hot
--65--/--70--70-- Warm
--60--/--65--65-- Safe
--25--/--30--30-- Cool

Tcase = CPU temperature
Tjunction = Core temperatures

This is as easy as it get's.

I dont know what all those questions mean.
That is why I felt it was complicated.
I saw that my CPU was within specs, But I wanted to make sure
I was reading everything correctly. Someone did a great job on the
Sticky, the deal is Me not your specs.

What CPU Stepping? - dont fully understand. I have a multiplier of 9.5 and a vcore of 1.316. I left it set to Auto in the Bios. I do not have any speed stepping software that I know of. When not in use the cpu multiplier drops to 6

What CPU cooler? - Thermaltake CL-P0370

What ambient? 73-75

Which 72c? CPU temperature or Core temperature? I guess core temp since the program spec's say it is measuring cpu core temp.

Which temperature monitoring utility? - Core Temp

Which Prime95? Large FFT's or Small FFT's or Blend? No idea I just downloaded it for 64bit Vista and ran Torture Test

For what duration? an hour

Case covers installed or removed? installed

All fans at 100% RPM? I believe so

also 4 - SATA 500gb HD
GrForce 8400 and 8gb of ram

You have somewhat of a steep learning curve ahead of you for awhile, so read everything you can, Google what you don't understand, look up the definitions, and search out as many answers as you can.

Best of luck!

I thought I posted the question to seek out answers.

So, From your guide it would seem that my processor's Core Temp is ok.
E8x00: Tcase Max 74c, Stepping E0, TDP 65W, Idle 8W

I simply want to know if I am reading that correctly.
The idea of trashing a processor while I learn is stupid if all I need is a yes or no.

I think the vcore was to high on auto. I am adjusting now.
I was able to get from 73c to 55c just buy reducing the Vcore.

current Vcore is 1.216
I am testing with prime95 as we speak.
Real Temp says the Core is 56c
Core Temp say the Core is 63c
100% load on both cores.

I thought I had a really good Heatsink. It was the one this site recommended for a p945. Is it to old or something?

Computer seems Stable
3999.0 Mhz

For a 45nm dual-core they are high, even at 3.8ghz. Mid-60's is as high as you want to go.

My 45nm quad is at 3.3ghz and only hits 56c on one of the cores after 2 hours of prime.

Thank You.
My temps peak in the mid 60's at 4.1ghz after 1 hour of prime45
Base Core temp is around 39c, Bios says lower
The problem was my Vcore, auto was making it go to high.
Current Vcore is 1.248 Auto was in the 1.3 range

I also figured out what steppings are, mine is A revision E0
