Please help me overclock my E8600 with EP45-UD3P Mobo

[joynrg]

Hello, I just finished builing my system last week. However I am a newbie for overclocking.

My specs are shown below.

CPU: Intel E8600 @ 4Ghz
Mobo: GA-EP45-UD3P
GPU: XFX GTX 260 Black Edition Core 216
RAM: G.SKILL 8GB (4 x 2GB) DDR2 1066 (PC2 8500)
PSU: CORSAIR CMPSU-750TX 750W
Case: Antec Nine Hundred Case
Monitor: Panasonic 46-inch TH-46PZ85U VIERA Plasma
HD: WD HDD 500GB 32mb Cache Black.
OS: Vista 64bit Ultimate
CPU Cooler: ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler
Optical Drive: SAMSUNG 22X DVD±R DVD Burner with LightScribe

I overclocked at bios, using all stock volts. changed most setting to manual, except some of the features to auto.
I could have achieved 4ghz with 400 X 10 mutiplier. ram at 1066 with 2.66D.

I want to overclock it to over 4.2, and 4.5 if possible.
All manual setting suggetion will be very appreaciated.
1 Weird symptom that I have with this overclocking is when I run CPU-Z or ET6, it's multiplier is changing back and forth to X10 to X6, constantly switching with Clock speed to 4000mhz to 2400 mhz also.

Please suggest/share your stable overclock bios setting, and solution for the problem that my multiplier and FSB/Clock speed switching back and forth.

Thank youi very much for your help in the process!

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?

[x.clay]

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.

Thank you very much for your help! It worked like a charm!

[joynrg]

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.

[Lsdmeasap]

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

Here is what I would advise for 4Ghz + >>>

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!

[SpeedEuphoria]

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.

[Lsdmeasap]

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?
