Hello,

I am new to both overclocking and overclock.net.

I need help with my E7400 overclock. I am stuck at 3.6ghz(350x10.5)
I have spent the past two weeks with google trying to find a solution and I am getting frustrated. Here is my problem:

I want to go faster but if I up my fsb to more than 350 but no more than 360 it will start to boot then mess up when Grub starts to load. It just starts giving my a bunch of crap on the screen then goes into Kernel panic. If I go above 360 fsb it will not boot at all with 10.5 multi. It will boot at 400x8 but is not stable. My goal is to get to 4ghz can someone please help me get there.

Also I feel like my vcore(1.37500 in bios 1.35 idle from sensors-applet 1.36 load from sensors-applet) is awfully high compared to other people I have seen on here. If I can't get faster I would at least like to find a way to lower my vcore.

I hope this post isn't too noob but I am a noob so forgive me if it is.

Here are my BIOS settings:

CPU Ratio 10.5
FSB 350
PCIE 100
FSB Strap to NB auto
Dram freq auto

do you have your memory divider set so that it doesn't run over stock speed? I know that's a simple thing and you probably did, but I just have to ask.

4.0 will be very difficult to reach for you. Those e7400's normally don't get that high without an insane vcore. As for the vcore you have going to it, yes, that's as high as you should go.

and I noticed you are running stock cooling??? is that the case? if so, you are maxing out the temps on that thing.

Re: memory divider

I am below stock speed on my memory.

If I can't get all the way to 4.0 I want to get as close as I can. I have seen several people that where running 4.0 with less vcore than me. That is what I don't understand. Why do I have to make my vcore so high. Have I missed a setting somewhere else that is making me do this?

I am on stock cooling until my zalman gets here. I am not stressing the pc too bad until then. Right now it runs 33 33 at idle and gets into the high 60's when running cpuburn-in. I am just trying to do some of the work now before my zalman gets here and I can start really testing it.

what is the VID of your chip? if it's a high VID, you will probably have to pump more voltage to it for less performance versus a comparable e7400 with a low VID.

As you can see, I have an e8400 and I can't reach 4.0 because of the rediculous vcore it requires to get there. I'm at 1.36v and can't get a mhz above what I have in my sig without linpack errors. My VID is 1.225v

3.7 is usually what the 7400's will do.

 

[shughard]

I'm not sure how to find out what the VID of my chip is. Please tell me how and I will post it.

 

[slngsht]

you can download core temp and that should be able to tell you, as well as keep an eye on your temps.

 

[slngsht]

oh, and you might want to try dropping your cpu multi from 10.5 to 10 and raising your fsb more. That will make your rig feel more responsive. Don't forget to change your ram divider accordingly though, and you might need to bump your nb voltage a notch or two. It will introduce more heat on the cpu though, so if you are on stock cooling like you say in your sig, you may not want to do that just yet.

I am running ubuntu 8.10 linux I will have to google how to find it in linux.

 

[shughard]

Ok I googled how to read VID in linux and came up blank. Does anyone know how to do this?

 

[slngsht]

if you still have the box, the sticker on the box may have your VID on there.

see my image (cruddy cell phone image)

No luck there. unless it is some how coded in the #s on the tag. It says:
Prod Code Bx80571E7400 MM# 900516 FPO/Batch # 3845A315 ver # E53246-001
pack date 01/22/09

 

[slngsht]

yeah, sorry that wasn't any help. mine had it on there, but it is the first-run production of the 45nm e8400's and they may have done things a bit differently. Good luck.

Try this: NB volts 1.26
FSB term 1.35
And is your mobo with P43 chipset?? They're knowed as under 400fsb limits...i have the same prob. I'm thinking on changing my mobo

 

[shughard]

thanks minu94 i will try this tonight and see what happens.

my chipset is p45 on a p5q
