I have an E8400 and have been running Prime95 for 15 minutes as I'm posting this (lol. Yes I will run it for a long period of time... just not right now ) I raised the bus speed to 380.0 MHZ x9 = 3420 Mhz, and my core voltage right now is 1.36v and the CPU is hitting 58ºC tops with an average of about ~54ºC. What temps should I start to worry about?

Thanks.

keeping it half way of tj is ok for max temp, start worrying when theres 20ºC-30ºC difference from tj max.

Ok, let me explain: This is my first overclock... ever. What is TJ Max? My distance from it is 36... whatever that means.

Reduce the voltage if you can. I have 1.344 V for 800 Mhz overclock with Q6600. In your case, 420 Mhz for 1.36 V is a lot, i think. Reduce the voltage or increase the frequency. then run the prime test.

its the estimated temp if reached, will cause crashes and may fry the cpu

Dude really i have an e8400 with EP35C-DS3R

I can run it at 3.6GHz with only the slightest voltage increase! Like 2 incraments above the default voltage.

If anything Put 1.25V in the BIOS and 400MHz FSB you will do FINE i was running orthos for 2 hours!

Well thats with my e8400. AS they are all different, your results may differ, but really 1.36 V is WAY TOO HIGH! I would get 4.0GHz+ at that voltage!

I did 9x400 (3.6GHz) and left everything else stock. Works fine. Running 25/26C at idle (with RealTemp), 10C more with CoreTemp.

that voltage is way to high for that speed.I'm running mine at 3.6 ghz with 1.18125 vcore voltage.

lol. Ok ok, I'll tone the voltage back to maybe 1.2v~1.25v and take the FSB up to 400Mhz. I just did what the BIOS told me to! It said turn off this, turn off that, enable this, enable that. Set this on auto... I did so, and when I took the FSB up to 380, it did that automatically. How high do you think I could get with my specs? I have 4GB of Corsair XMS2 DDR2-800 if that makes a difference. I need my computer to:

Last me at least 2.5 years at that speed.
Be completely stable under 100 percent loads whilst doing huge video transcoding

Suggestion for a 3.6 o'c
set vcore to 1.275 and see what happens, don't change anything else
you can go down a notch at a time if stable at 1.275
I set mine at 1.262 for 1.216 actual in cpuz

Hi, I have an 8400 on an ASUS P5K-E Board. My max OC was 3.6 with Cosair 6400 ram, I just upgraded to 4gigs of OCZ 8500, and just went up some more, now currently running 3.96@ 1.168 Volts. I notice a huge improvement in the new ASUS boards from my older Gigabyte board and ECS (junk) board. I bet I still have room to go. But that is all for tonight, going to let orthos run... oh SpeedFan and HWmonitor show CPU temp @ 32 idle and Cores @ 44&37
