My retail 45nm Wolfdales - E8200 + E8400

This is why you don't buy the first silicon off the line...

Yeah yeah we all know that.. but I'm a reseller for Altech and AustraliaIT and actually make a few bucks when I resell them so it's no biggie for me

Well after some testing it's still better than an e6600 or e6750:

e6600 3.6ghz 1.43v orthos blend air lapped
e6750 3.6ghz 1.44v orthos blend air
e8400 3.6ghz 1.24v orthos blend air (stock volts)
3.8ghz 1.30v orthos blend air

Will test 3.9ghz later. This chip does not scale well with increased voltage on air from my previous attempts at 4ghz air testing...not even up to 1.45v...
Superpi times at the same ghz are slightly faster...

Yeah it's hard to b1tch, there's extra cache and new instructions

So its like a G0 stepping of the newer cpus right.

Who cares about Orthos stable really? It's not like you get this CPU's to "play" Orthos or think about "hmm... i'm bored... let's start up some Orthos" anyway. Your CPU will never get stressed in real life like it does with Orthos so no point in going for lower clocks just to get it "orthos stable".

Unstable in Orthos, or Prime etc, means the system is generating errors. You may not see them in everyday use of the system. Not until it's too late anyway. As the errors build on your hard drive, the crashes and BSODs will start and grow more frequent, until you have to reload. If you are lucky, you don't lose anything when it crashes.
As I said, your system is either stable, or it's not.

You should give Folding@Home a try...

jeez man your threads are doing my head in sometimes

how can you make such a conclusion on a couple of chips tests

have a look here mate

E8400/E8500 mainly purchased in Oz and all CPUs are hitting monster clocks on air

you really need to give it time matey

i bought a couple of E8500 CPUs like eva and mine bench up to 4.7GHz on Corsair Nautilus 500 no worries and it's summer in Australia

[g1raffe]

Jesus G1raffe I'm in Melbourne too and bought 3 E8400's trying to get 4GHz stable

By the way what does CPU-Z say your Vcore is when you have 1.35V in the bios?

You sure its not your RAM limiting you or something? Whats the highest voltage you have tried up to(windows, not BIOS)

Whatever I set in the BIOS becomes ~0.12V lower in windows, so 1.35V will give ~1.23V.

I need to set ~1.47V in the BIOS, giving ~1.35V in CPU-Z for 4ghz Prime95 stable.

I've done 1.50V and it is almost stable at 4GHz but not quite, I have the same Vdrop as you

[Xvys]

I disagree about the first run chips being inferior. My E6300 was packaged in 07/06 and bought 08/06. It ran 533FSB x 7 (3730Mhz) with my old P5B vanilla and reached the same 533FSB stably with my new P5K Deluxe. It booted at 540FSB, but the voltage required was more than my Freezer 7 could handle. The cpu been used reliably 24/7 ever since (490FSB x 7 = 3430Mhz @ 1.35v).

I am planning to buy the E8400 and just plop it in my existing system. I anticipate being able to run it at, say 450FSB x 9 = 4050Mhz for 24/7 use.

Anything less, then the 2-3% performance increase does not justify of cost of upgrading to the Wolfdale.

[nzbleach]

which stores have the E8400 in stock in aussie that ship internationally?

[adamsleath]

they saving the nicer chips for e8500 - which is as it should be i suppose.

so cant expect miracles from all 82/8400's...

will chips get better or worse over time?; either is possible.

i'll wait and see whether there are any mediocre e8500's, as i'm sure thats wot i would get based on previous experience....so 4 me it aint worth the $$

4 some1 looking to upgrade to a c2d i would not get anything but a penryn now.
i dont even see the point of having an e8200 at the current pricing - ridiculously close to 8400 in pricing....and they are basically the same oc ability?

just have 8200 or 8500.

Are people complaining about MHz, or testing for FSB?



Lets see some retail FSB testing, so we can see what kinda numbers we can pull if cooling isnt a limiting factor

[Garrett]

Still nowhere to be found here in The Netherlands... just great
Where do you guys get them?
Preferably shops that ship internationally... no make that worldwide LOL

[jarthel]

what good is that then?not to sound rude...

if it can run the user's usual cpu-intensive app (e.g. video encoding and etc. doesn't have to be necessarily orthos), why can it not be good?

[Speederlander]

So that was SetFSB achieved? What is the best FSB you can boot into and do things with a modicum of stability?

[dinos22]

with both cores enabled 566MHz (3DMARK06 stable)

i've posted 561 tests i did but did do some higher FSB as well

Try crunching or encoding video. Sieving will beat the hell out of your processor, I've nevere seen temps as high as when I'm sieving.

[AriciU]

I don't deal with stuff like that so... For real life stability i use compiling since i'm a Linux user. Compiling brings my temps to around 55-58C so i think it's pretty stressfull.

BTW: by Orthos stable i mean 8 hours Orthos stable. At my current settings (in my sig) i'm Orthos stable for around 3 hours or so then an error pops out of the blue on one of the cores. I agree that if Orthos craps out in less then 30mins then you should not consider those settings as stable IRL.

[g1raffe]

Max stable FSB for me is ~530 on E8400, nothing too special.

[dinos22]

Phase or water?

SS phase

water 530MHz dual 32M Superpi stable on both E8500 CPUs i have

[railmeat]

nice clock for a few pi runs,but what can u call stable GOOD air\water for the 8500? but what in your mind is 24\7 stable,GAMING(intensive)with NO issues etc?
