should i be happy and just run with it

e7200@3.8 at 1.31v on water temps are fine i am on a p5q that can handle 1600 fsb which i am at 400*9.5=3.8
problem when ever i try to go above 420 fsb it becomes unstable.

spec: cpu-3.8@1.31v
nb on auto
sb on auto
vtt auto
ram 1066 adata 1.9v

i am willing to go more but everthing was just so easy to get to 3.8 i was like wow and just got stuck there i have gotten it up to 4.0 but i was not sure if i was doin it right because the only thing that made it stable was 1.42v which i think is to high not really sure with the 45nm chips. So i have played with the nb, vtt and even the ram v up to 2.2 to try and get it stable but no luck only thing that seems to work is high vcore.

at that vcore temps hit 69 70 c in realtemp distance to tj.max was still 30c and realtemp has been calibrated so 70 means cores hitting thermal limite of 74c if i am right if i am wrong someone please correct me

stable temps @3.8 are 58c with an ambient of 25c in my house

In all honesty, I really don't think you'd see that much higher performance that what you're getting now. What you're already running is indeed rather powerful; the most you'd get beyond that point would be insignificant at best.

But, on another note, that processor is capable of going beyond 4 GHz, but it would probably require that you raise the voltage more. If you can't get it at 1.42, then for the longevity of your processor, you might want to stop.


Intel Master

■The Vcore limit for your E7200 45nm CPU is 1.3625 in CPU-Z under 100% workload with Prime95 Small FFT's.

■Intel's 74.1c thermal limit shown in their Processor Spec Finder - - is Tcase (CPU temperature) not Tjunction (Core temperature), which is a very common misconception.

■The difference between CPU temperature and Core temperature is a known value, which is 5c at Load, and is shown on page 4, figure 5 in the following Intel document -

At Standard Ambient 22c, you still have some headroom. If you want to learn how to test, calibrate and monitor your temperatures, then check out the Core 2 Quad and Duo Temperature Guide -

From the Guide:

Section 6: Scale

Scale 1: Duo
E8x00: Tcase Max 74c, Stepping E0, TDP 65W, Idle 8W
E7x00: Tcase Max 74c, Stepping M0,TDP 65W, Idle 8W<--E7200
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
E6x50: Tcase Max 72c, Stepping G0, TDP 65W, Idle 8W
E6540: Tcase Max 72c, Stepping G0, TDP 65W, Idle 8W

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

Tcase = CPU temperature
Tjunction = Core temperature

Hope this helps,

e7200 often hits a HUGE wall at 4 ghz

the e5200 is the better overclocker for budgets

compu from my understanding then i am only on the warm side of things and i have read through toms temp guide thanks i am using tj.max and i really just don't like speedfan thanks for all the help folks

another note can anyone think of a good upgrade that cpu that would not just be wasting money when i will be buying an I7 in a couple of months
