Questions for overclocking E8200

post #1 of 15
Thread Starter 
I have Thermaltake's Silent Tower installed as a cooler. For other info such as mobo, CPU and RAM please check my system info.

I freaked out this morning when I noticed that my temps (stock vcore and FSB) were reaching 60C under load (monitored by Everest 4.50 & CoreTemp 0.99).

Then I started doing some reading on the net and I discovered all about TJMax and how it is erroneously assumed to be 105C for 45nm CPUs by those two monitoring programs.

So I downloaded RealTemp 2.6 and, of course, temps dropped by 10C (as TJMax was set to 95C).
So my max temps are now 50C (as monitored by RealTemp).
I should add that my ambient temperature is 27 to 28C.

So far... so good.
Surprisingly I wasn't able to increase the FSB by much on CPU stock voltage so I set everything to AUTO in the BIOS (except PCI-e frequency which I set to 100MHz).

I was able to read FSB 410MHz but since everything was set to AUTO I noticed my VCore was now reported as 1.30V.

After running Orthos for about 20 mins I noticed my max core temps were 49/50C (check attached picture).
I left Orthos running for about 1.5 hours and everything was fine.

My questions:
- Is VCore 1.30V safe for my CPU if overclocked for 24/7 ?
I noticed some people say one should check the sticker on the CPU box for VCore info. Mine says (1.25V max).
Does that mean the max VCore I can use is 1.25 or am I still safe under the recommended 1.3625V ?

- What should I do to try to go higher... like 3.4 or even 3.6 and what are the limits (VCore, VDImm, Load CPU temps...) that I should respect in order not to damage my hardware ?

Thanks guys.

Welcome first off to be honest you should take your v-c out of auto and set to manual as it will raise as fsb does,Yes 1.30is ok for 24/7 i Belive as long as temps are under control,use core temp to to compare and just like slit the diff,imo

Ok can someone please explain this ?

I set VCore manually to 1.28V (it was 1.3V when I left it as AUTO).
That's is! That's all I changed. Didn't touch anything else in the BIOS. FSB is still @ 410.
Now for some reason Orthos will generate an error and stop after about 1.5 minutes of "Small FFTs" (priority 9) testing !

***! I mean most E8200 owners can easily go beyond 3.3GHz at stock VCore ! What's going on in my case ? Do I really need to leave VCore at 1.3V to be able to successfully overclock my E8200 to 3280MHz ?

Ok now our in manual up the v-c to get it stable,in auto it will up as your fsb increases,so try that,imo PS:you can lower it untill it wont boot then uptill it does lots of trial and error you just want the lowest stable v-c and o/c.

As Phil, mention You don't have enough vcore now. you'll have to up it till it is stable again.

When OCing you should keep all voltage settings on manual. That way you are aware of the voltages you are at.

I know. That's why I was surprised and I said that most E8200 owners can easily go beyond 3.3GHz at stock VCore. I've seen people reach 3.6GHz on an E8200 without having to up VCore at all.

Should the lowest stable VCore be 1.3V for FSB 410MHz ? I mean if it was my RAM that was holding me back then I should be able to reach that FSB without increasing VCore. Right ?

- What FSB speed should I be able to achieve while on stock VCore ?
- If my CPU box says: "VCore 1.25V max" does that mean my stock VCore is 1.25V or is it the max VCore that I should never exceed ? I'm asking so I know what to set it to manually.

The only advice I can give is because someone can do it, it doesn't mean that all E8200 can do it. Each CPU + motherboard can behave differently. For me at 3.5ghz, my voltage is around 1.33v

You can do up to 1.3625v, as this link will show. Some people go by this as 24/7 safe voltage. http://processorfinder.intel.com/det...px?sSpec=SLAPP. Many have gone as high as 1.45v on E8400,E8500 for 24/7. What ever you feel comfortable at is where you should keep your vcore at.

Ok, thanks.
So is it normal to have a Vdroop of 0.2V ?
When I set my VCore to 1.3V in the BIOS it then shows as 1.28V while logged on to Windows.

You mean .02v? Lucky you. I have .04v on my motherboard.

Vdroop is about .02V when I'm logged on to Windows and idling.
It drops by another .02V when the CPU is under full load.

Do you have a drop of .04 when idle or under load ?
