First off, just increase the FSB until it isn't stable. Then that's when you increase the Vcore (CPU Voltage) by increments. I don't know much about overclocking this particular E7400, but I would just suggest starting at the FSB speed, times the multiplier and then put the voltage up to the maximum, and work your way down.
Trying to Overclock E7400 to 3.4GHz
I would like a little help overclocking my Computer. I just Got a E7400 to replace my old Pentium D that died. I ended up replacing everything on my computer in order to figure out that it was my CPU that hit the crapper.
Here my Current Set up:
Intel E7400
Gigabyte EP45-DS3L
ATI X1950XT 512MB (Soon to be 4850HD 512MB)
4GB(2X2GB) OCZ 1066 DDR2
550W Thermaltake PS
3X 36GB Raptors
120GB Serial 7200RPM HD
Antec 900 Case
DVD ROM
DVD RW

I would like some suggestions on how to get this up to set up to run at 3.4 to 3.6 GHz and run smoothly for 24/7.
Any help would be grateful. Thank You

Wow. You're awesome for providing these screenshots.
Based on what I see here, I say that before you do any overclocking, there are so-called "limiting" features in the BIOS that must be disabled. They are not overclocker-friendly. Disabling them will help you get the most out of your overclock.
However, here are the tools that you need:
But in general, there are various ways to overclock. For example, I like to go straight to an overclock that somebody else is getting and then tweak from there. For example, I saw somebody getting 4.0GHz with 1.280V with their E8400, so I did the same thing. After some testing, I discovered that mine actually needs 1.320V to be truly stable (and I mean stable with the Linpack test in OCCT. Otherwise, I only need 1.304V). Yeah, that saved me a ton of time.
Another method is to first find the lowest necessary core voltage to be stable at stock speeds. After that, gradually increase the FSB in tiny 10-20Mhz increments until it's unstable, and then increase the core voltage until it's stable again. And then start creeping the FSB speed up again until it's unstable, and then bump the core voltage up again, repeating this procedure until you're satisfied or something. And then when you're ready to call it a day, run a 12-hour Small FFTs test, then a 1-2 hour Linpack, and if it passes, then you're good. But the temps need to be watched too. But more on that later. Oh wait, before you call it a day, you should run like 30-minute Small FFT stress tests and like 15-minute Linpack tests to perform quick little checks after each tweak. And if you have nothing but time on your hands, than even a 1-hour Small FFTs test can be considered a "quick check" (as well as like a 30-minute Linpack test).
Another method is to crank the voltage to the highest "safe" voltage (such as 1.3625v), and then see how high of an overclock that will get you.
Either way, BSOD's and other failures are really good because they help you know when it's time to increase the core voltage, or back off the overclock a little.
Finally, I just want to say a few words about overclocking the memory: try to see if you can change the Command Rate (CR) from 2T to 1T. You may have to increase the voltage from 1.8V, or you may have to increase the CAS# Latancy (CL) to 6. Either way, you'll feel a performance gain, and it's worth a try!!
That's as much as I can think of right now. As I said: more later.

But welcome to OCN, Talec. If you want your system in your signature like the rest of us, then just follow these simple instructions:

Based on what I see here, I say that before you do any overclocking, there are so-called "limiting" features in the BIOS that must be disabled. They are not overclocker-friendly. Disabling them will help you get the most out of your overclock.
- Spread Spectrum (disable anything that says it)
- Intel Speedstep, EIST, or Enhanced Intel Speedstep
- C1E Enhanced Halt State, or anything that says "C1E" or "C1" in the name.
- CPU Thermal Control, or anything that has options of "TM1", "TM2", and "TM1 & TM2".
However, here are the tools that you need:
- Real Temp Some calibration may be necessary, so be sure to visit the Installation & Calibration Page for some awesome information/documentation).
- Orthos (for stress testing. It's Prime95, but with a better GUI and it lacks the features in Prime95 that overclockers don't use) Run the Small FFTs test for about 12 hours or so. Then when you're focusing on your memory, run the "Blend" test for like 6-12 hours (run these tests while you sleep, while you're at work/school, etc.)
- OCCT This is another stress testing tool. The "OCCT: CPU" test is very similar to Orthos. It has the Small Data Set test, which is the Small FFTs, the Medium Data Set, which is the "Blend" test, and the Large Data Set, which is the Large FFTs test. But most importantly, this program has a Linpack test. This stresses the CPU much, much more, and it also creates 10-15°C more heat. If your chip can pass like an hour or two of Linpack without overheating, then you know everything is good. But still do the other tests.
But in general, there are various ways to overclock. For example, I like to go straight to an overclock that somebody else is getting and then tweak from there. For example, I saw somebody getting 4.0GHz with 1.280V with their E8400, so I did the same thing.

Here is my OC. Maybe it can help u a bit.
Take a look at the Bolded settings. Those are the ones I changed. This is the best I can do. These changes merely prepare the system for overclocking. As I said, these are not overclocker-friendly features, so they must be disabled. I hope somebody else will come along to fill in the rest.
Anyway, as you can see, I was only able to figure out the Advanced BIOS features. Please refer to my first reply in this thread for more information, and be sure to read it carefully.
Please note: in addition to these, please find and disable anything that talks about "Spread Spectrum".

I'm not worthy of reputation points, though. Oh well.

I'm not really sure. I think this is getting a bit beyond my "scope of support", as one might say. I'm pretty limited.
However, based on the screenshot of both the Memory and SPD tabs in CPU-Z, I'd say you're already at a good start. As I said before in my enormous "tl;dr" type of post above, try changing the Command Rate (CR) to 1T. However, this may either require a slight boost in voltage up from 1.8V, or maybe just an increase in the CAS# Latency (CL) from 5 to 6. I think it's likely that you'll need to do both. For example, I had my memory at 4-4-4-12-2T, 800MHz, 2.05V. That's a stock setting (similar to the 3 stock settings in the SPD tab you have. I have 3 as well). When I increased the Command Rate (CR) to 1T, I had to boost the voltage to 2.1V and then slow down the CAS# Latency to 5 from the previous setting of 4.
Going from 2T to 1T gave me a noticeable difference in performance. I mean, I could feel the difference right away. However, I haven't done any benchmarks, as I'm not the type. But I talked to somebody in chat who performed a benchmark to compare 1T and 2T, and they said certain numbers were nearly twice as high.
![]()
Now, if I increase the memory's clock speed, then I really don't feel a difference. So, that's why I leave it at stock (click on my system).
By this point, you may be wondering what the maximum safe voltage is for your memory. I don't know yet. But as a general rule of thumb, I would say that you should try to stay away from the range of like 2.2V and 2.3V. I mean, stock is 1.8V for yours, where mine is a range of 2.0V - 2.1V, so it's much safer for me to use 2.2V and 2.3V than it would be for me if I had the same memory you have. Yours may have a range too, and it's likely printed on the sticker which is on your memory sticks.
And finally, be sure to read every last word people type to you when you ask for help (including every last word that has already been typed here). I mean, we're all doing the very best that we can, but it kinda feels like you're skipping a lot because there is so much to read. But trust me: it's worth it. You'll get to a certain point down the road where you'll feel so awesome inside because you took the time to read all these things. The reason for that is you will eventually have a very deep understanding of things and then you'll find yourself easily helping others as if you're some kind of expert in the field. Not only that, but imagine for a moment right now how that deep understanding (which will gradually get deeper as time goes by) will benefit you with your own rig(s).

Thanks For all the Help. I was able to over clock my CPU yesterday to 3.45 GHz. 345 x 10, upped the Vcore to 1.325V. Turned off all one you said and my computer booted up perfectly. Currently I have only run one test, a 1 hour Linpack test. It passed without errors My Computer runs 28'C idle and 63'C at 100% load. Not sure if these are ok, but I believe it should be fine. I will run some more tests tomorrow while sleeping and at work. Thank You for all the help. I will do some overclocking of the Ram also today and see what I can do. THANK AGAIN FOR ALL THE HELP.

And that load temp just right for the Linpack test with this overclock, especially with this voltage. It's the same voltage I'm using, and I'm getting about the same Linpack load temps!
Anyway, you're very welcome. As you can see, it's a pleasure to do whatever I can to help. I can see that you're well on your way to having quite a good, clean and solid overclock!
I look forward to the possibility of helping you again soon!

hi ive got a post in the official overclock thread and you will see that im running a e7400 @ 3.41 ghz on a stock cooler
change the fsb to unlinked set the fsb at 1300. fsb voltage @1.3v.
cpu multiplier 10.5x cpu voltage 1.22v
i reach temps of 67 max and thats on a stock cooler i think you could drop that voltage to atleast 1.25v - 1.28v have a try . i keep knocking down my voltage until i run a test which crashes then i up it slightly until it does a test without crashing

Because when you can overclock directly from the BIOS, then it's STRONGLY recommended to do that because we can never trust software to tweak the BIOS. One reason is that too many people have had problems.
So, using software to overclock a custom-built is almost blasphemy!! In other words, the question is "Can I use software to overclock this computer that I just built?", and the answer is "No. Never. A thousand times no. For the love of your system, NO! Do it directly from the BIOS."
