My stock vCore is 1.275 shown in CoreTemp.

Update:
4050MHz (450 x 9) PL 8

Can u show proof that it can pass the Prime95 test in more than 1 hour?

Why should I?



-pWs-

Here's my E7400@3.675Ghz@1.29v

Passed the 1 hour prime95 test, but temperature quite high..

Slowly i'll OC higher and show the test here..

Question here..
How much wattage differences if i overclock my E8200 from 2.66Ghz to 3.2Ghz
in idle/load without bumping voltage?

erm yerp..
this is for E7xxx only..

this is my first time doing overclock. by having assist from mr goldfries and asamkipas, i managed to overclock my e7400 at 3.55 ghz stable. credits to them bcoz 'tak jemu' reply my pm all day long. thanks broS.
using rs xigmatek and gigabyte p35 ds3, for me to get 3.5 ghz stable is like reaching at heaven. im not a real gamers. just want to try out

testing using software OCCT, stable.
prime 65 at more than 3 hours, stable.
thanks again to goldfries and asamkipas

p/s: rs xigmatek allowed d max temp only at 58 degrees. wat a bargain

Here's my 7400 results@3.72Ghz@1.32v

Passed the 1hour Prime95 test with maximum temperature of 73C! If i open up my casing, it can drop 4C. Definitely my casing airflow is bad!!

ur not having a bad AF casing with only 4C drop. i've seen some casings with 10C difference between open and closed casing

haha thanks. I already wondering to buy expensive casing, but then i think not all the time my CPU will load till above 70C. Maybe no need..

Change to a better cooler.

As requested.
1 hour prime95 test. Small FTT.

4Ghz@1.38v
Nice!!
Your max temp only 68C? wow! watercooling?

Anyway, here is my statistic of OC with my 7400 so far:

Speed (Ghz) - Volt-Temp (cel)-Temp (kel)- Speed/Volt
3.49 1.24 65.00 338.00 2.814516129
3.56 1.27 67.00 340.00 2.803149606
3.67 1.29 70.00 343.00 2.84496124
3.72 1.32 73.00 346.00 2.818181818

It seems that the most optimum Speed per volt is at 3.67Ghz.

Yup. Max temp is 68C
Using air cooling.

-pWs-

wow. Using Dark Knight huh? How much is the current price u think?

Not sure. Bought it 2nd hand.
Btw, able to boot in Windows @ 450 x 9.5. But not stable in stress.

-pWs-

Haha, should be careful.. U'll fry your CPU..

I guess still fine provided the temp & vCore pumped.
But for 4.2GHz, it is not worth the vCore needed already. Might as well using 4.0GHz 24/7.

-pWs-

nice my E7200 with that vcore last time can hit 3.7-3.8..
4ghz jump to 1.6v - lol
