ok heres what i got

E7400 @ 4.0 (500x8)
Ram ddr2 1000 5-5-5-15 (rated 1066)
VID 1.1125
CPU 1.31v load
NB 1.55v
cpu pll 1.89v
cpu vtt 1.30v

this board is stable at 520fsb 24-7 at 1.4v so the nb voltage is actually a little high

i tried merely increasing the voltage but that doesnt help it takes only 1.31v to get 3.92 stable but 4.0 is a no go at 1.38v

Ideas???

I would increase the VTT to 1.4V and then see if anything changes. But, that's the only thing that I can think of.

By the way: nice goal!!!

thanks

im trying that now along with turning the "host slew rate" from weak to strong and upping pll tp 2.0v

will post results

EDIT: WOW its 5 min orthos stable now loading at 62c

WHOA! It looks like it may have worked!

Moar VTT voltage. Unless it's not safe to exceed like 1.4V. Help anyone?

Hey, Sorry I can't be more help, but I don't have much info that you don't already have

I'm also OCing an E7400 and I was wondering what you used to get that 3.92? Right now I've got 3.85 stable @ 1.36v with 366 x 10.5 (my mobo supports 1800 - or "450 actual" is this right?) I also wanna see what my highest fsb is with 8x but not sure if I should surpass 450...?

I'm not pushing too much past 1.36v even though my core temps never passed 51* (more like 44* ish running P95 for hours...) and I want to see how far I can go. so far I haven't touched any other voltages. I'll edit when I've got some numbers from the bios.

One weird thing is my core temps are completely unchanged at 32-34* even when gaming or up-ing voltages. So, is my cooling just doing a really good job? or are speedfan & coretemp messing with me? or is this just normal?

Bonus: What's the theory on lower multi vs. lower fsb? anyone?

Thanks a lot

I don't want to thread jack or whatever it is called but, read a post titled "E7400...wait for it...stock cooling" (its late/early been up all night getting this OC)
I have pretty much the same hardware as you, or the ones that matter to OC i guess. vandassen.

One of the helpful posters in my thread said something about having faster FSB is better than more multiplier. I guess the more multi = more heat = bad OC.
This is just my guess. Totally unfounded, just off the top of my head.

Back on topic.

What are; (what do they do)
NB 1.55v
cpu pll 1.89v
cpu vtt 1.30v
I never figured this out.
I left mine all on Auto.

Are you referring to Mattb2e's reply, Post #29?

To be honest, I don't know enough to talk about whether or not you'd be better off going with a higher FSB using a lower mutlipler vs. using x10.5 and whatever FSB gets you a reasonable overclock with stock cooling.

However, CPU speed is king. In my eyes, it's best to use the highest multiplier so that you don't have to be worried about being limited by any FSB limitations. The main reason why people lower the multiplier and raise the FSB is to see how high their CPU's FSB can go on their motherboard so that they know the system's limits. Then they bring the multiplier back up and begin overclocking. Or, at least it works something like that.

So, if you were to ask me, then I would say to use the 10.5 multiplier, and go for like maybe 3.5-3.6 GHz. I think that might be the highest you can expect out of this CPU with stock cooling without running into excessive heat, thereby causing instability no matter what. But I'm being slightly conservative. You might even be able to get 3.65 GHz with the 10.5 multiplier.

Anyway, from the list of things you posted, the only one I am 100% certain of is the VTT. The VTT is the FSB voltage. That's all I got!

Ah thanks that cleared it up for me at least. Much appreciated!
