Best voltage for E8400 @ 3.6 GHZ

1.175 Is the Voltage i currently have set, Running Orthos with no errors. Is this an alright voltage E8400 @ 3.6 GHZ at the moment. thanks in advance!

yea thats fine. the lower the better but always check for stabilty

Yeah,good voltage is the lowest possible thats still prime/orthos-stable. Theres no way of telling exactly as every chip/setup vary. 1.175 is pretty good though, I say

Yeah i ran orthos for 2 Hours and i Got A max temp of 61 C, usually staying around 58-60 C and No errors. I think this is stable, its amazing how low 45 NM chips can go  

how low   i cranked my e8400 upto 4.6, now my e8600 can go way over 5ghz. on stock volts my e8600 can do 4ghz

Just ran 3D Mark 06 and i got a CPU Score of 3326 and 13,186 3D Mark 06 Score, Improvment from like 12,300 before  

Im not smarting here but 2 hours testing doesnt mean its stable, I wouldnt settle for less 12 hours. Although recently i had an error on 19th hour which i only discovered by accident, now im questioning the stability of my own setup, but thats a material for a new thread I guess

you only test the system for stabilty for aslong as the system will be doing cpu intensive tasks, eg rendering you need a min of 24hours of stabilty, but for pifast you only need 5sec of stabilty, and everything in between.

Well, my definition of stable system obviously differs from yours. I want my system to be stable regardles what I throw at it and how long i make it run. I dont want BSOD as an effect of few hours of work, even though i only work on my pc ocassionally. OP will do as he wishes

I have my E8400 at 1.275 Vcore @ 3.59Ghz and after 12 hours of Prime95 I reached a max temp of 54C. But when I crank it up to 4.05Ghz @ 1.34Vcore I get 70C

I just put together a machine with an E8400 and all i had to do is up the FSB to 400, i made no voltage change. What is the stock voltage again for E8400? and do you guys think i should try for more @ stock voltage? I tested with Orthos @ CPU, small, priority-10 for 36 hours and no errors... Is that the right test to be running as well?

bump*

Doesnt seem to be working anyway, but i guess i'll try it...

Best voltage really depends on the chip. I ended up with one that needs an awful lot of help to get to 3.6. I'm running a vcore of 1.325v. Again, just have a bad chip. max temp after 13hours of prime95 is 53°C.

I have an 8400 (CO) that is a terrible overclocker. I had to put 1.2375 in bios just to get 3.33 out of it, and 1.25 to get 3.375. It will run 3.42 at the same 1.25, but not 3.465 (385 x 9). I had to run 1.26875 to get 3.465 stable. The E4600 that I did use would go a lot more (% wise) before having to increase voltage.

Yeah, I have the C0 revision as well, though at the time I wasn't into overclocking and I was upgrading my Pentium D to the new Wolfdale cores, so I didn't exactly care at that time.
I also have my RAM on really tight timings, so maybe if I loosen em up a bit I could push it higher, but at the current moment I don't really need anything more than 3.6GHz.

how do you guys know what type of e8400 you have?

I have the newest Revision E0, And Its confirmed Stable i ran Orthos for 10 Hours and It Ran Stable. @ 3.6 GHZ With 1.175 voltage

What is the vid of that chip?

The program CPU Z will tell you what stepping the chip is. Always download the latest version.

Stock havent touched that

I did the same with an E8500- set the FSB to 400, set the ram to 1:1, set the PCI to 100MHz, cranked it up and used it. At 3.8GHz the CPU so far stays under 40C.

I would always set a Core voltage and not leave it to auto if you haven't

OMG!!!!!!!!!!!!      

well to shock you even more , mines a C0 revision so not as good as the E0 stepping , yet im running at 3.6ghz , all i did was change the fsb too , no voltage change at all! , all on auto in my dfi x48 ut t2r bios   , just shows some chips are different to others

Not shocked by the Voltage, but by the answer to the question of "what is the Vid of that chip?"

We won't go into the whole VID of chips thing, but I'm sure he was just requesting the VID stated by a program like Cpuz.

Yes, it was a little sarcastic, SORRY, it won't happen again.

This thread is a classic example of people who know bugger all about overclocking and come on to a forum and brag about their bull shite clocks, temps and voltages.

Learn how to overclock PROPERLY before posting on a forum and misinforming people!!! (even though it's only Tom's which no one takes seriously anyway).

Thanks.  

WoW
A necro troll bump. Now what was that about being taken seriously ?

And that's his second post, wonder how far back he went for his first one, maybe years  

I've got my E8400 clocked at 3.6 Ghz. CPU voltage is set at 1.075 in the BIOS.

Beautiful E0 revision chip. Temps never go higher than 48C on full load.....
