is my E8400 Overheating @ this clock? - Page 3

post #21 of 63
Thread Starter 
what the math involved with determining FSB? like i'm assuming 1400 = 333 and 1600 = 400, whats the math involved i guess that would help a ton. and i'm going to reduce the voltage a bit.

I have seen this way too many times....intel's stock cooler is impossible to attach and a LOT of people (including me a couple times) dont get it on fully, and contact with the CPU is bad, so load temps are through the roof.

99C is too hot, 60C is just fine and prime for some awesome overclocking

ooo nvm, 1400 / 4 = 350, 1600 / 4 = 400 , little brain power, was a long day.

Yea you got it now. You will need to increase your NB voltage as well. I have a quad core so it requires higher voltages but mines at 1.4v 1700 fsb. You will probably have to play with the HT voltage too, do not go above 1.4v on that (you probably wont need to go near 1.4). Which E8400 did you get, the E0 or C0?

Okie its running at 3.6 ghz now.

let me know if this looks right.

I lowered my vcore to 1.25625V
all the rest are auto

Increased 'NB PCIE Frequency (Mhz)' from 100 to 105mhz

FSB to 1600
MEM to 840

CPU-Z says this.

1.216v

Core speed : 3599-3600
Multiplier: x 9.0
Bus Speed : 400.0 mhz
Rated Bus : 1600.0 mhz

Did I do it right?

also according to Real temp idling its at between 37 and 39 Celsius.

is 75c about the temp it should stay at for being on load?

Do not increase you NB PCIE Frequency. Leave it at 100. Other than that it looks fine, not to sure why your core temps are so high. maybe you need to remount the cooler?

Temps still seem quite high. Perhaps your case doesn't have enough airflow and you have high ambient temp.

My E8500 overclocked to 4275MHz with 1.36Vcore and a Megahalems cooler and under full load stress testing, 59C. Idles at 34C.

How have you got the fans arranged on the case, radiator etc?
post #29 of 63
75 seems too high.. For reference, my E8400 C0 @ 3.6ghz idles at 33-36 with a OCZ vendetta 2 cooler in a rather poor airflow case (only 1 case fan @ 700rpm), and doesnt go above 50 under prime95.

I'm wondering if maybe have the vcore voltage at 1.26 and the rest of the voltage on auto is causing it to run warmer. I just dont know what the correct voltages should be for the other one.

idle atm with NB clocked back to 100mhz @ 3.6 its at 37c.....

if I did the other voltages manually would that decrease the temps?
