New Rig, what kind of overclock?

post #1 of 27
Thread Starter 
Okay if you look in my sig rig, I have updated it with my new computer. UPS forgot to send the Antec 900, so I should have that tomorrow.

My E8400 is an E0, VID 1.25v

How many volts for a 4.00ghz overclock.

Temps are load 47C according to Realtemp, Coretemp reports about 50C with a 3.4ghz overclock, stock volts.

This current case has NO fans, what kind of temp drop will an Antec 900 give?

I get 4Ghz overclock at 1.26v. However I run it at 1.296v to get it stable for very long times.

I have no experience with the Antec 900, so I won't go there. But since I do have an E0 E8400, I will give you my best answer.

Thanks to the Newegg reviews on the E0 by others who have the same mobo that I do, I started out with 4.0GHz, and 1.28V. But, it was unstable (Orthos), so I bumped it up one notch, and it ended up at 1.296V (CPU-z). It was much more stable, but not 100%. And so then I bumped it up one more, and it ended up at 1.304V, and it has been 100% stable ever since.

Actually, I'm considering bumping it up another notch even though I can run Orthos all day with no problems. I'm experiencing some infrequent and strange software problems sometimes. Like Firefox will sometimes crash, or maybe a game will quit unexpectedly as though I killed it with the Task Manager.

As you can see, Commended is getting 100% stability at 1.296V, and mine needs 1.304V, possibly a hair more. So, I recommend starting out at 1.28V, and then seeing how much it wants.

And as for Real Temp vs. Core Temp, always use Real Temp for these 45nm CPUs. It's about the only way to know the actual temp.

I usually start on pretty high volts and start going down after that on my quad.

my son got fantastic results with his antec 900. his 6400+ AMD with a Xiggy 1203 was reporting a realtemp of 29 to 32 idle when he overclocked it to 3.6.

Thanks to this thread, I finally decided to stop being so lazy and I increase the voltage a tiny bit. But I had to do two bumps to see any difference in CPU-z. It went from 1.304v to 1.312v. But, as long as I don't get too close to 1.3625v, I think I'll stay pretty comfortable.

Thanks for the help guys!

Wow an AMD at 3.6ghz is impressive.

Just gotta wait for UPS to get here with that case...

Is 4.00ghz a good speed for 24/7 usage? I don't plan on upgrading for awhile.

yeah, 4.0 is fine no problem 24/7.

i run my e5200 @ 1.31v 3.54 all day

thats a 1ghz overclock so i cant see why an e8400 cant run 4.0ghz all day

Yep I now have my e8400 e0 stepping at 4.0ghz at 1.3v in bios. My old e8400 c0 was at 4.0ghz at 1.34v in bios.
