E8400/E8500 overclocking thread!

MSI P35 Platinum motherboard and Kingston KVR667 1Gb RAM. (Yeah, I know, I'll change the RAM as soon as possible, but I wanted to find its limits. I have already booted with RAM 800Mhz by increasing volts at 2.0.)

Currently being at 3.46, the computer gives me 37 at idle and 52-53 in full load under the ORTHOS stress test.

What I am planning is a set and forget situation for 24/7.
For example FSB 400x9 (3.6Ghz) fot the cpu and 400x2 (800Mhz) for the RAM.
Would I give my cpu too much heat there? Probably it will be somewhere near 55oC on full load.
What soyld be the voltages to stay there with no restarts or freezes? I would like to give the minimum voltage needed.
Thanking in advance,guys...

Your RAM is obviously the limiting factor here. It's impossible to do more with that RAM. Even at 4.05GHz, my DDR2-800 RAM is limiting me from going above 450x9.

I say it's your ram. Try increase the vcore slightly, if it doesn't work, then it's most likely your ram. E8400 shouldn't have any problems running at 3.6GHz at stock voltage.

My E8400 could do 3.8GHz at stock voltage.

What about the temps?
When the processor is on full load, is reaching 55-57 degrees celsius OK? I do not have a watercooling solution and I am anxious to know if such temps will have an effect on my processor.
Short or even long term. (More than 3 years of use for example)

Those temps are high I am not running watercooling the Hyper212 on my E6550 and my Katana2 on my Northwood Celeron 2.6 both never go over 50C under full load

hmmm this thing is strange with e8xxx series
i have noticed that same but how i see cpu is directing mbo bios to rise voltage when you oc it
i have asus x38 mbo and when i push fsb higher i get higher voltage automaticly dont know why and how i have checked all on my mbo
i have even returned EPU chip to normal (without pencil mod) and i get same
when i push it over 420fsb i get voltage on 1.3v but my cpu works on 1.12v at 333fsb

[Chai]

Did you set the voltage to auto?

[generalRage1982hrv]

nop
have updated bios and it is all ok now

[Chai]

Ah...I have to update my BIOS to make it work properly. uGuru wasn't working properly as well.

Different processor, different cooler, different monitoring software/sensor, you can't really compare that way because the accuracy can be very different. Then again, I wouldn't consider 50+ load high.
