This is my Bios setting runnign 4Ghz very stable for 3days.
Any suggetion on manual setting to clock around 4.2 to 4.5 will be appreciated.

Thank you!

Bump** Anyone?

Re: Please help me overclock my E8600 with EP45-UD3P Mobo

The change in CPU multiplier in CPU-Z is a result of Intel's Speedstep which reduces the CPUs speed when not in use. It can be turned off by disabling CPU Enhanced Halt (C1E) under the advanced settings.

Bump! Does anyone successfully overclocked E8600 with all manual bios setup to 4.5ghz or more? Please share your setting with me if possible, my setting is shown at the 2nd post.

Re: Please help me overclock my E8600 with EP45-UD3P Mobo

It isn't very likely at all that you can do 4.5Ghz with that cooler, and for sure is not going to work with Auto everything w/ 8GB of ram

Please do post a link to your ram

It boot up some how and look stable until this morning since last night, but would you recommend this setting for 24/7 use? My Antec Case's fans are set at "Med Speed" and CPU never go over 50C (Only when I use "OCCT" it went over 50C).

I want the best performance out of system but i don't want my systems to be water cooled. What is your recommend 24/7 setting? Do you think i can use that clock 4.27ghz for 24/7 with that cooler?

Thank you very much for your help again!

Re: Please help me overclock my E8600 with EP45-UD3P Mobo

So what are you doing to say its stable?

For me I like to do 8hrs of prime or OCCT or both. Some people just do 2hrs and say its good, while others do 24hrs. Basically how many hours doesnt matter, what matters is that it does pass at least 1-2hrs, then it should play all your games or Fold w/o issue. If you have random issues its not stable and I would adjust something till those issues go away. Again running a stress test for 8hrs should be plenty.

Re: Please help me overclock my E8600 with EP45-UD3P Mobo

Yes, stable would be passing some tests as mentioned above. Memtest86+ and Orthos is what I use. Linked here is Plenty of testing tools Post #3 >>>

http://forums.tweaktown.com/f69/intel-burn-test-27994/

Grab Memtest86+ 2.11B and run 5-10 passes then you know your ram is stable. As for your CPU you can choose from many different tools and methods all up to you

24/7 depends on your temps. What was your max temp in OCCT?

Thank you for your input Speed! i am a newbie so pointing out about stability issue was right.
I ran OCCT for 6hours, and passed it. I guess then it's stable?
but after i passed the test, while i was playing COD5, it crashed and rebooted and lock up on post screen ....
Now it reset to F4 bios from F7a automatically!!!

So I lowered the clock to 4.0ghz (400x10) with stock voltage and it passed another 6hours of OCCT without problem...

Do you think it's better to flash the bios back F7a or should i stay with F4?

I know flashing the bios is risky, and I read all the post about make mobo to brick state...

Now i am confused if i have to flash bios or not.!!

And those options :

I come from an asus P5B, so I have too much more things to set in the UD3P :) (P5B was so simple compare of the UD3P ;))

Thanks for your help :)

Re: Please help me overclock my E8600 with EP45-UD3P Mobo

So, I set the CPU Vcore to 1.30 V ;)

I will try to run OCCT for some hours :)

edit : after 2 pass, no errors in MemTest86+
After 1h of OCCT (CPU : OCCT mode), no error.
I launched some minutes ago, the "CPU : linpack" test for 1h.
I'll tell the results after :)

edit 2 : After one hour of Linpack test, no error :)
Can I consider O/C stable ?
I will play some games now to test the GC :)
