Yeah, on my second wolfie now, and both requires more after a while, this seem to have entered with 45nm ..
One thing at a time. Drop the CPU multiplier to get it out of the picture, then look for stable RAM at your target FSB. Memtest overnight with no errors.Quote:

Yup I should have been clearer, DMF has the right idea.
Ordinarily we'd do mobo FSB limits first (old school), but the presumption is that the Intel chipsets, particuarly your P45 these days can go far beyond RAM or CPU limits anyway.
Normally the RAM part would take quite a bit of time to figure out as well, but setting cas 5 should allow most cas 4 RAM to scale well beyond what your CPU will hit. Of course, confirm this with memtest and at 6x multi to confirm.
So once RAM latency and volts, necessary NBv for those respective FSB settings are in place, then it's pretty smooth sailing: CPU increases will then obviously require more vcore.
Yes on every single one of my 4 wolfies.. I had to up the voltage to run prime stable. I've never had to up the vcore due to system instability. Doesnt have to pass prime to be stable.
my e8400 came from new egg...but its still a luck of the draw...tiger direct advertises there e8400,s to be rev E0...but they charge sales tax in my state...:up:......QUESTION..do guy,s think 1.4200v vtt ((aka cpu termination)) will end up killing my chip for 24/7...im sure its a little less then whats set in the biosQuote:

what about 500x9?
will try it tomorrow
I see a few more people got a Q829A congrats .
I will post pictures with a camera of my Air cooled
system and my temps I think you guys will be shocked.
I believe voidwarranty temp claims.
I know the chip will do crazy things , they are a fantastic batch.
lol vid 1.25 so that will prove vid means nothing.
Here is my q829a
http://i294.photobucket.com/albums/m...e35/600FSB.jpg
I just received a Q829A159 from Newegg which I ordered on Friday, shipped from NJ warehouse. Hope it's as good as some that are posted here! It will be going in to a DFI P45 JR so I will likely be back to ask about all the extra BIOS settings that I'm not used to, I need to wait for a few other bits first.
I ordered a new chip this past "Black Friday" and it came in today...
E8400-E0 Q832A161 with a packdate of 9/25/08. It has a 1.2250 VID. I've not done much testing on it but it appears prime stable (4 1/2 hours large FFT) at 444x9 with 1.20v idle and 1.184v/1.192v load!
My replacement E8600 Q820A727 (1.25 VID) which I recently got back from Intel RMA requires around 1.232v load to be stable at 4.0GHz. Hopefully this new E8400 will continue to scale with increased vcore.
@PolRoger
Do got your northbridge fan hooked up?
I did'nt notice it in your TPower shot there
under the system fan rpm's just asking..
could not get get 500x9 stable but this is stable :)
4x1gb ocz @ 1187mhz 5,5,5,15 2.17v actual

@gurusan,awesome!god i wish i could get my processor to do 9x500 or higher,maybe ill try 9.5x? and see how that goes. and again very nice clock
thanks. i've been through a fair amount of chips and this is the best chip I've found. stepping Q828A127....VID is only 1.25V
just goes to show you that VID really doesnt mean anything in wolfies :/
yea the only thing i notice in vid is the lower ones run alot hotter. my e8400 w/vid of1.23 runs so hot that once i clock above 4200 i cant even run intel burn test cause temps rise straight up into the 70C's where as my e8500 never goes above 52C at 4300 on IBT.
If you mean the Cooler Harbor fan that comes with the board... no I've never hooked it up. This m/b has never been installed in a case just on a HSPC open air test bench and if I need addititional cooling I just lay/prop up an extra 92mm or 120mm fan.Quote:

Might just wait till the quads go cheaper and do a 4gzh quad chip :)
Keep the overclocking coming. Anyone have a C0 with 4.5ghz or higher? How much volts?
Nice OC Gurusan we have almost the same batch it seems . Im loving it and benched a 3d suite 03,05,06 last night @ 533 *8.5
4530 I can do exactlly 1.408 but bumped to 1.42 for 3d stability , it went all night no errors and max temp on air was 50C !!!!!
It was my first run of that suite for a single gpu comp and beat the 8th spot I know this thing will do much more. Oh btw I am finding 1.22v MHC is really nice and stable for me @ 533 hope this helps guys .1
After a couple months, mine went from 4.0 stable at 1.216v up to 1.248v. But i also have had my chip up to 4.6-4.7Ghz a few times. Not sure if that made the difference, but I've benched 4.6ghz alot since its needed 1.248v and it hasn't changed.Quote:

I did some more testing on my new E8400 (Q832A161 1.2250VID) today. I started off with +0.75v of cpu vcore using 500x8.5= 4.250GHz. At idle CPUZ showed 1.256v/1.248v and under load running Prime large FFT 1.240v/1.232v it seemed stable and after running a decent bit I decided to go for the what I consider the "big money shot" for 24/7 air overclock of 500x9 using +0.150v vcore. CPUZ was showing idle at 1.325v/1.320v and load was 1.312v/1.304v and sometimes vdroop would drop to 1.298v. I still don't have this completely Prime stable it has been failing around 2 1/2 to 3 hours large FFT. I'll probably put this chip in one of my other boards and continue with more testing.
that's a mighty fine chip you have there! congrats
Thanks gurusan.Quote:

Idle is now showing 1.328v and load stays mostly on 1.304v and I didn't observe it dropping below 1.3v like my previous settings. I'll now see if it can run overnight while crunching SETI/Climate Prediction.

plus i have a CO stepping so that might hold me back too.
Just got an E0 E8500 with 1.175 VID. So far seems to do 4.6ghz 1.408V.....temps are really high on this one though (78C under watercooling). Shame as this seems like a really good chip, with some proper LN2 or osmething I think it could be very successful :)
yeh its weird gurusan some chips require very low volts at high clocks but once you apply over a certain voltage they get very hot i have a q822a435 and mine only needs 1.24 volts to run at 4.34ghz but once over about 1.375 volts it gets very hot, other chips need a much higher voltage to run at same clocks but run cooler even though they are taking more volts

Thanks for that, but 1.2125 is not really low VID....most are 1.25, some 1.225, others 1.2125.
1.175 is really quite low for an e8500 in my experience and it does run burning hot. At the same settings this chip is almost 20C hotter than my other 1.25 vid e8500
yep. my e8400 w/vid of 1.23 runs about 15c hoter than my e8500 w/vid of 1.25
I agree with you about it not being low VID... but that is still one of the best E0 chips (air cooled too) that I've seen.Quote:

Just picked this up the other day. E8500 Q827A658
Primed all day at 9.5x440, just kicked it up to 9.5x445. Half hour into it, looking pretty decent so far.
EDIT: Almost 4 hours, I'm going to fold on it for a few days at these settings.
I've started exploring with +0.200v vcore.
yowzers that is a nice chip
OMG! polroger that is one awesome cpu! keep pushing
PolRoger killer chip man ! with some good ram that sucker will do 5.0
Thanks guys.
I also did some initial testing with +0.250v vcore which runs ~1.424v idle to ~1.400v load. I'm able to get into windows and do some superpi at 533x9 but it wasn't prime stable. This chip runs hotter than my 1.250 VID 8600 with prime temps hitting in the lower 60C's with higher vcore. I think I'm going to put this chip on my DFI UT P45... it has better BIOS voltage increments which will help in getting 533x9 stable.
nice one gurusan. i wish i could get mine over 4400.still no luck
It depends on the chip but on air it's pretty difficult... ;)Quote:

A little update. Every kick up in speed now takes a big jump in voltage. 4.4 might be in reach, but I don't know about 4.5.
Hello all, my first post..here we go :cool:
E8400 FPO A807A269.

I can boot Vista having 1.20 idle vcore and 1.184 load (but not stable in orthos).
What do you think guys?
Should I be worried about the vcore of 1.248 idle and 1.232 load?
Thanks
@ joebar, my air set up is very cool.using air conditioned air, at 4400 temps never exeed 46-48c.ican prime for hours at 4400 but as soon as try to go to say 4411,prime fails after about 5 minutes-temps still only 47c.thishappens using different multipliers still no luck.but ill keep trying
My ram is at 1164mhz right now, 5,5,5,15. 4x1gb OCZ SLI 8500s..they can do 1200mhz on 2.19V actualQuote:

.9500 is a low VID chip and it looks like it runs hot. Are your load temps 75C with LinPack or with Prime at 445x9 /1.248v idle? Is 445x9 stable at 1.232v idle?Quote:

Having 1.232v idle is stable with Orthos but with Linpack not quite.
Note: It is C0 stepping
I was missing some of the screen shots when I first viewed you post. I now see that some of your CoreTemps show a 1.1625 VID... I don't think that 1.248v is too much but those temps... that 10 hour orthos run showed peak temps as high as 82C/84C... your chip seems to run pretty hot.Quote:

Hi guys, my E8500 just arrived an hour ago. I specifically bought the E0 stepping (who wouldn't lol) and I am very impressed by this thing so far. This is my third boot (once I figured how to enable the .5 multi) and I haven't even begun to tweak the system yet.
Motherboard: EVGA 680i AR
CPU batch: Q820A916
FSB: 1896MHz (474MHz)
Memory: OCZ ReaperX PC-6400 @ 948MHz 5-5-4-18 2T
Vcore in BIOS: 1.425
Vcore in CPU (idle) 1.4v
http://i293.photobucket.com/albums/m...ys/4500MHz.png
I don't like this voltage for everyday use but I may be able to tweak it.
Having this CPU in my gaming motherboard when I have a Maximus Formula boxed behind me is a bit irritating lol :P
1.4v is fine for 24/7 use...heck...1.45v is fine in my book
nvm i'm an idiot.
I thought people have had 45nm chips die on them at just over 1.4v? I reckon I could get it stable at 1.4v but the FSB is another thing... I'll have to try some stuff first.
What's the program of choice for these chips - Orthos or Prime95? I'm not interested in IBT :)
I've ran Orthos again (1.248v idle, 1.232 load) and never got past the 75C.Quote:

What do you think max 75C in load sounds "safe" (or be in the safe side)?
@Rippo
Oh yes you passed 75°C. Your Tj.Max temperature is wrong. It's fixed in beta versions of Real Temp but you can set it manualy to 100°C. So, watch at your temps with 5°C more ;). Although, Intel's max recommanded temperature is 72.2°C so I think that's too hot for just 1.23V.
Bullet92, I've previously set the TjMax to 100C for 1st core. Second one it was to 95, so basically I hit 75C.
I tried just to get to desktop at 5GHz and failed, but I'm forgetting this is only an Evga motherboard and 525MHz fsb is kinda pushing things lol.
I did however manage to boot at 4.75GHz:
http://i293.photobucket.com/albums/m...ys/4750MHz.png
I'm very happy at the moment with 4GHz on 1.25v but I'd like to aim to aim for a higher clock speed - 4.5GHz is easy for the CPU but I'm not sure how the FSB will hold up...

If you really wish to run at 4.0 you could always try the 1.232v idle setting for 24/7 and see if you ever have stability issuses in your day to day computer activites.Quote:

I have my E8400-C0 set with just enough cpu voltage to be stable at 4.0GHz and not have any crash/resets with seti/climateprediction running up to 24/7. I have it set so that it doesn't proccess while I'm active but otherwise it is always crunching.
I've found that if my systems can do Seti long term then I usually don't have problems with stability.
wow 4.2ghz --- 4.9ghz overclocks in the last two pages. Very impressive.
These clock speeds/voltages are because of the quality of the chip, not my skills as an overclocker lol:Quote:

And there you have it!
So far the best I can get is 4400MHz at 1.368v (1.4v BIOS), which seems pretty happy so far. I'd rather less vcore though, so I may take it down to 4300MHz.

Some E0 E8400s are doing 4.5GHz stable, but if you want really low vcore you should get 4GHz with 1.2-1.25v no bother. I think my E0 can do 4GHz on less than stock volts, but I haven't primed it yet at 1.23vcore.
What Bios are you guys Using? im using the 1406 bios from Asus, witch should i use?
Thanks
