Worst VID E7400 ?

Its the default voltage required to run its stock speed.

One chip might do it at 1.2v and another require 1.2875V to do the same stock speeds
 
And still bears no relationship to how it clocks or even what voltage you need to run it at stock.

Tbh, the only vids which seemed to matter were the VID's on q6600.

My q9650 has a VID of 1.25v yet will run overclocked at 4Ghz, 8 hours prime stable at only 1.23v, less than the supposed stock voltage required to run it at 3Ghz.

Just try and see. You might be pleasantly surprised.

Yeah but I've yet to see a low-VID chip that doesn't clock well. In my experience high VID chips don't necessarily clock poorly, but low VID chips pretty much always clock very well.
 
with 1.43V set in bios

1.38 actual - max overclock so far is 3.6 stable .... not that great really !!

and a Q9650 at its stock clock - I'd say a VID of 1.25 is pretty good

I agree with the above btw I'm sure there is still some correlation ..
 
i was just stress testing with prime95 for 2hours with the e7400 running at 3.6ghz, it ran stable for the entire 2 hours no errors, max temp was 79c

but i tried to play wolverine after, crashed after 10mins gameplay :s

and now im resetting some bios options, so confusing with this new motherboard. :(
 
thats better than mine - anything above 3.6 (and I feel like 1.435V in bios is already pushing it a bit) - it doesn't even fail prime nicely - it blue screens and reboots :(

temps only get to 60C with the CPU passively cooled with a Ninja Mini :)
 
same cooler as im using, mines confined in a Lian Li v350b, replaced all fans inc CPU fan in there with Noctua ones, and it still gets pretty damn hot.

any chance you or anyone is using a DFI LP JR T2RS board aswell...? theres so many settings i want to cry.

My point is that q9650 is the max VID you can get for this cpu yet mines clocks to 4.4 - 4.5Ghz and even at 4ghz needs less volts than some lower VID q9650.

You might be right about a low VID chip always clocks well, I don;t have enough experience of them but I can say my high VID cpu clocks better than most q9650's so a high VID isn't the end of a good overclock.

And isn't 1.35V the worst VID you can get on a E7400 so yours is not the worst be some margin.

However, in saying all of that, it would appear to be a dog at overclocking as half decent ones get to 4Ghz but I have seen people putting 1.5v+ to get that far.
 
My old q6600 was an averge 1.2750 vid chip which clocked quite nicely, 3.8 on air with 1.512v, currently testing my q9550 at 3.6ghz, running 2 notches above vid of 1.200, if stable im gonna try dropping it a bit.

yup ! - never mind :( - I mean can't grumble with a 1.1gig overclock - just I always seem to get worse of the worst !

3.6 gig was ok for about 15 mins of prime - but at 1.5875 Vcore !! lol
 
<update> 3.7 gig on the E7400 was not stable at 1.45V in bios - 1.4V actual !! lol

3.2 gig was ok at 1.21V

and just testing 3.1 at 1.1V

not sure what I really need for HTPC purposes but I suspect 3.0gig and above is sufficient for majority of needs :)
 
VID is deffo not reflective of how a chip clocks.

Sold an E5200 last week that had a VID of 1.2875v. Managed to do 4ghz with it at 1.35v easy peasy.
