Are all E8400's created equal?

Are all of the E8400's decent clockers (Within reason?) or is it only specific steppings that people get good results with? Whats the difference between Wolfdale and Penryn?
 
No. Wolfdale based CPus are the dual core 45nm Variants, Penryn are the Quads.

E0 are supposedly better than C0 as a general rule for overclocking, but people still get reasonable results with C0, so don't worry too much.
 
As above.

They're all pretty good. Both e8500's i've had were lovely clockers.

The first was a C0 and clocked to 4ghz on 1.3v the second is an E0 and clocks to 4.5ghz on 1.32v.

The E0 obviously clocks better but it runs around 5c warmer at 100% load when comparing clock for clock.

EO's seem to need a touch less voltage to break 4ghz, mine does at 1.3v whereas a lot of CO's seem to need to be pushed up to 1.4v+ which is starting to get into the area of concern with the 45Nm.
Given that these chips go from cool to hot during the overclocking process quite quickly it's preferable to keep the volts as low as poss.
Never heard of any E8400 that wouldn't clock happily to 3.8ghz.

Yup, Wolfdale is the codename for the E5000 Pentium Dual Core and E7000 and E8000 series of Core 2 Duo desktop processors.
 
I've got a E8400, its a very fast chip. Wont be needing an upgrade untill the iCore7 start getting a lot cheaper. I havent overclocked since I have no real need to plus I'm not sure about voltage
 
The new E0 steppings coming on-stream seem to be getting good reviews but, tbh, all E8000 series chips have always clocked well.

My E8400 was one of the very first, dating from Jan/Feb this year and has been running at 4Ghz since it was installed without any problems at all.
 
Fox you'd happily spend hundreds on your car, or on a GTX280 but you're splitting hairs over the CPU? Considering you seem torn between an older tech Q6600 or a new E8400 chip why don't you just wait a while, save some more money and get a 9450 or 9550 chip then you'll have the 45nm process and a quad.

Plus by the time you get that money you might decide you're not so bothered anyhow. Sometimes when I'm looking into computer hardware I spend ages researching all the options and tearing my hair out only to realise later I didn't really need to upgrade after all, I just told myself I needed too when I didn't.

I need a CPU ASAP to release the E4300 I've currently got for use in another machine. It seems daft to buy another E4300 when I can spend double the money on an E8400 or Q6600 and displace the E4300.
 
I have upgraded recently since my old mobo and videocard died due to heat issues so although buying numerous parts, the cpu, in my mind, was supposed to be where the most money was spent, or at least, the most thought put in. A chap at a computer store put me off buying one version of the Q6600 (1466fsb I think), which I now regret a little. My 6600 o/c well to 3.0 without any voltage change though any higher than that and the PC usually needs to be restarted once again before I arrive at my desktop. So, I have the option of upping the voltage on my present cpu or going for the 9550 yorkfield. So, Fox, take your time and get the best you can afford. Though I haven't made a big mistake, I do partly regret the choice I have made. My overclock of 3.0gig from the stock 2.4 is certainly a substantial improvement but when I have had it working on around 3.3 there is a hell of a difference, just not ready for voltage tinkering yet. Oh yeah, and get a good cooler ;)

No problem, £60 ish gets you a skinny E5200 Wolfdale and £130 gets you a phat E8400 Wolfdale, both great chips with their own pros and cons . . .

Yeah it would be better to pickup a slightly newer tech 45nm chip, cooler, cheaper to run and fresh silicon to tinker with.

I've got both the E5200 and E8400 and they are excellent cpus, still not sure which is best but I will in a few weeks.

If your not a student and want to throw some bucks at a great processor I would put the new stepping E8400 right at the top of your list, otherwise it's the E5200.

Well I am a student so I just bought a Q6600 for a ton. If its no use then I'll flog it on at a later date and get something else, my decision in the end came down to 'Which comes up first' and a Q6600 it was :o

At the end of the day I could afford an E8400 or even a Q9450 but you have to draw the line somewhere, this month has already seen a WD Black Series and a GTX280 so I really couldnt justify the extra. Hopefully this system will do for a year or so now :)
