No. But i'm entitled to give my personal assumption on the subject.
I still believe the cpu is not the culprit to this clock degration but some other factors.
I had this problem with DC opteron where it ran stable for days at 2.9ghz until i decided to push it further but came to dead end so when I set everything back the way it was it became unstable even at stock speeds. I did everything by the book-clearing the cmos, taking out the battery but nothing. At first I thought it was the cpu so I ran it on my older epox939 board and the cpu ran just fine. I poped it back in my dfi and decided to reflash the same bios and boom the opty ran at 2.9ghz stable again.
Sorry but I just don't buy the fact 1.4v would degrade this cpu in just a few days (unless you try it without the hsf). 1-2 years maybe but not 3-4 days..It's impossible. Did someone mention their cpu's blew up or something? Well there you go. Faulty PSU is the biggest killer to all components.

I got the exact same batch as you loc.o
BUT in running it in Maximus Extreme, and i must admit, this board really sucks.. I got a feeling the cpu can do alot more, it craps out on about 500 in this board, but it boots without a glitch at 550, god damnit.. :)
what do you think, i got same batch as you, and my VID are as low as 1.0500
and 510 is a no go into windows, nomather what voltage on the important things... how was your experience with maximus?
regards.
This board was released more than 6 months ago, it will need a bios update to work with 45nm. You'll need a 65nm or older cpu to flash to latest bios before you can use it.
You may be lucky however, and the board might just come with support for 45nm. You should probably ask in the IP35 thread and see what folks say. Goodluck.
Havent really tried much but sounds familiair. With maximus bios 0401 and E6600 550FSB air and 590FSB with dice was fine. Now using bios 0907 and an E8400 (can do 590 air on Commando). Simular settings for Maximus as with E6600 tests but not much over 500fsb now either. Rather sure were both missing a setting here and there because board shouldnt have a problem with it i guess..
I may have the worst Q748 there is... :mad:
It needs 1.35v for 3.8ghz (which is the max stable oc). 4.00ghz is just out of the question regardless vcore...
Return it tomorrow ASAP! :p:
Tested on P5E. That's for ppl thinking that P35 is the problem. No Q748 is the problem... ;)
Im really sick of it , what can that setting be? its not an unknown fact that x38 cant do very well, the only board ive seen getting good FSB are the P5E3 WS Pro..
maybe i should try a P35 board? and noo, no commando, im using ddr3 now.. :)
think im gonna sell this one, cant take this anymore making me nuts..
regards.
I got 545fsb on my max formula; I'm pretty happy with that. I believe I can go higher with relaxed performance levels but max fsb is not what I'm after.
The best way to judge the strength of what I consider to be "shoddy" overclocks is to ran some 3D benches with them for the following reasons:
1. the guy who did 600fsb with the p5b-deluxe had pci-e at 1x (a common problem with that board)
2. the performance levels get very relaxed past 400 progressively towards 500 and beyond. My P5B-D (C2) had performance levels around 11 with only 450 fsb.
I am running 9x500 with performance level at 7; something's gotta give - loosen permance levels = gain max fsb. Also, bioses still need to mature for x38, and remember, the strength of x38 is not necessarily just high fsb, but a combination of high fsb + performance (relatively lower performance levels).
Even though x38 is more or less a tweaked-for-performance derivative of P35 chipset, wasn't it meant to be the replacement for 975x? Or is it P45?
What I'd like to see, because I've done it on my x38 board, is a P35 chipset doing 9x545fsb with performance level 7; and pci-e @ x16
ok Tbh, i have forgotten the Booster ehhh... ive allways had it on strong, and booster lvl 3 ... couse when i did have my conroe in , it didnt mather what i did it sucked nomather what, but ok, ill try to lower it a bit and check. ..bbl
thanks..

Got my E8400 with the Batch #Q746A447 Dated 7th Jan '08, last nite.
I'm on AIR (TRU120E) & ve a ASUS Blitz Formula board with 4x1GB PC2 6400 Crucials & a 8800GT. Trying 2 get is 24/7 stable at 4.32 (1.4Vcore).

Sigh only good for 16hrs 15min on prime 95 and it crashed again core 0 runs at 1.304v just fine but core 1 always crashes even at my current 1.32V I guess its time to bump the voltage another notch or 2 for my 24/7 clocks, I can see its in reach now though. Can load windows and run 3dmark 06windows at 1.42V @ 4.6 but gets too hot w/ my Tuniq at only 1350rpm. will need to replace the rear fan in my P180 if I want to push it more /sigh
Not true m8.
Windows and most apps inc Orthos will always read your DEFAULT MULTI.
Thats why when you lower Multi and Raise FSB you get a mad high reading.
CPU-Z however will read Multi/FSB and CPU Speed correctly.
Good overclocking Guide for E8400 is HERE
Thanks Zeus, I will keep my fingers crossed that you get an exceptional E8500 after your luck with the E8400. Same goes to MrCape and others who were unlucky first time.
It seems odd talking about bad luck when people are hitting well over 4GHz and not being happy, Intel really delivered with 45nm :up: You can tell the process is good when the standard heatsink is only half the height of the one for 65nm.....
Eventually I got the chip above 4.6 but the stock heatsink (stock off the 65nm X6800 that is ;) ) I am using as a temporary one could not really handle it.
Anyhow managed 4500Mhz for 3dmark rock solid at 1.5v.
http://service.futuremark.com/compare?2k1=9326402
I will see how it goes with the tuniq on it, I will be happy with this though especially as it will be going on a 780i eventually for SLI and I expect 475 to about the upper limit anyway, if not less.

Andy
Can anyone share the reported temps on their motherboard if it is showing correctly?
I just came home only to find a note from mr Postman telling me i just missed him. :(
Why do these guys always come late except for when you're a little late yourself?
The last time i waited all day long for my EK waterblock when it was delivered at 19:00 on a saturday!
Now i was home at half past 12 and missed him...oh well.
Have to wait another day, let's hope it's worth the wait but from observations i have a feeling that all E8500's do 4GHz stable at below 1.3Vcore.
Another observation is that Q748 and Q750 E8400's are the worst clockers but if the topicstarter could make a nice spreadsheet we can see that in a glimpse.
Anyone already noticed degration of his Wolfdale yet?
Q746A495 I have.
Demon^
I've noticed that Wolfies that require lowish voltages to get stable at 4-4.4ghz don't clock as high as those that need more voltage to get them stable at the same frequency's for some reason.

are you sure that this is the right vid?
boot up with default settings without EIST / C1E and check it again. CoreTemp read

VID 1.0500, E8500.
The board cant handle the FSB it seems, 500 is max boot into windows, 550 can post without problem... BOARD ISSUE!
gah, ive missed not being able to play with mine :(
It seems to let you adjust the PCI-E frequency independent of your FSB speed. If you are benching for a 3DMark WR it might come in handy.
emoners: There seems to be a few reports of the on chip digital sensors getting stuck at fixed values on the new E8x00 series. When overclocking it is kind of like driving with a blindfold. As long as you're stable and are getting some decent MHz out of it I wouldn't worry too much.

holy crap! who said Q748 were bad clockers?!!!
:slobber:
e8400 Q746a328 is a good clocker?
Mine is Q746A777 and for 4.2Ghz Orthos stable, I need 1.46V (actual).
I can boot into Windows and do Super PI @ 4.4Ghz though but it isn't stable.
It makes me feel I have a poor overclockable chip when almost all of you guys here can do 4.2Ghz at a much lower voltage. Do they pass Orthos? Just to see if mine is really that bad.
I use a program called RightMark CPU Clock Utility. It displays the (VID) voltage ID of your processor so you can compare to CoreTemp.
On the CPU info page it also reads the minimum and maximum voltage values that I think are built into the Intel C2D processor.
Here's how my E6400 looks:
http://img238.imageshack.us/img238/6674/vidnx2.png
I've been running my processor air cooled at 1.48 volts, 7 days a week for a year without any of the degradation that people worry about. It would be interesting to see how this program reads the new E8x00 processors.
It'd be nice if there was a table showing everyones batch in the first column and then req'd voltages for highest prime stable clock in the next few columns. I guess it's too hard to say if each guy is doing the right thing with his settings etc..
It would be even better to see all batches on the same setup doing the same tests, but that may be idealistic thinking. Wait, wasn't there some thread from a guy who had like five different 8400s and was testing them on the same setup?
Apparently, it's based on one poster and "his five friends". Apparently all of their 8400's died after a week, if I'm remembering the story correctly. The thing that stands out most is the statement that even the guy with only 1.41Vcore had his die prematurely. That sounds like bull, cuz there are people putting far more than that on this very thread, and not a single one has complained of a dead chip.
I think we have to wait and see for a couple weeks. If people are still throwing 1.5v+ at these and they aren't dying that's awesome.

http://img264.imageshack.us/img264/6...336loadnm2.jpg
Yup I agree, those guys are not noobs!
That's why I think we must wait and see much more data to see if these things can really survive with 1.4v+. Thanks to all the guys who don't care because your data is worth gold.
It's right there in the spec sheet that max volts for e8000 series is 1.45v vs 1.55v for e6000 series. So people saying yeah I did so and so volts with my e6400 is irrelevant. 45nm may be more fragile. Time will tell but I hope it's not true.
Urban legends spreads fast.
It might even be that 45nm is more sturdy than older chips.
I never wrote that 8 CPU's died . They just degraded . You should read more carefuly next time !:rolleyes:
Mainly I reported less Mhz stable . 8 cpu's till yesterday ... 9 today , as another user in a forum here in Greece today reported that his CPU has lost Mhz also.
Also , 3 QX9650 (Hipro5 , Shamino , Victorwang) . You can find the posts here in XS for these CPUs. Also there is one 8400ES that died while benching (ln2) .
A new poll has been opened in thelab.gr today and already 38% voted that they noticed a degradation ... 33% doesn't tried with voltage so they don't know ... and 16% voted that the clocks are the same .
I'm still strugling with my Mobo and E8400
I need 1.368v to run 4GHz, but in BIOS I have to set 1.485v , so it means vdrop is 0.117 :eek:
New BIOS is needed!!!
Read the Micron datasheet for D9 DDR2 memory and you will see that it is only factory rated at 1.8 volts. When people are overclocking they usually start giving their memory voltages like 2.3 or 2.4 volts. In my experience, bad memory is usually the cause of most performance and stability degradation. It will be interesting to see some reports from XS users how the 45nm chips are holding up long term, like maybe a month or so at 4+ GHz. :D
Intel wouldn't have raised TjMax if they thought otherwise. TjMax represents the highest safe operating temperature for a C2D so a bump up in this rating is a sign that Intel is pretty confident in these new processors, even at extreme temperatures.Quote:
It might even be that 45nm is more sturdy than older chips.
That is not vdroop, it is offset between what you set in bios and what is indicated by windows. What you need to do is launch P95 or Orthos and then look at the CPUz 1.368v. The amount it drops when the CPU is loaded is vdroop. Better yet, use a voltmeter and measure the REAL vdroop.
I really hope they are holding up well! I want to run these suckers hot.
I understand that in the past overvolting has been fine if you can keep the temps down, it's just that there are conflicting reports about 45nm. Reports that come from the same guys who love to throw voltage at chips, not the conservative types.
:rofl: :ROTF: :clap: I've even pumped 1.6250v (bios) set, and on posting, I saw CPU Overvolt warning, still booted into windows fine and trying to determine max clocks. I tell ya, once you broach the subject, people are going to be pointing to the cpu instead of troubleshooting other things.

Can you give me a link , how can I measure CPU voltage using a voltometer please.
BTW my English is not so good (I'm Polish) - I understand this offset is bad, and looks like my CPU is crap?
In Windows i've got 1.4V - in orthos 1.368 - that means vdrop is 0.032v.
Anybody got a Q745A346 pack date 17/01/08? I can't test mind due to Asus Striker Extremes amazing ability to fubb:mad:
I returned my Q748A242 today (max orthos speed was 3.8ghz :p: ) just to realize that all other cpus (10 of them) were Q748's also... :mad:
I decided to grab a new one Q748A141 and at least it's a bit better that the old. Right now priming for 2 hours @ 4.0ghz with 1.39v under load. Still a very high vcore for 4.0ghz but at least it doesn't top @ 3.8ghz... :p:
Seems like Q748's constantly produce the worst results. Better avoid them if u can... :)
The poll thread ? It's in Greek btw . (http://www.thelab.gr/showthread.php?threadid=46871)
What voltages are you running ???
Faster way is to use orthos/prime95 . Write down your current numbers , and check them after some days .
Orthos run so far, 1.2875 bios, 1.28 CPUZ for 4.0, will let it run overnight. I have loadline enabled so voltage in bios matches voltage in cpuz, vdroop is still ~.008 to .01. My batch in sig.
Wonder if any way that a single post could be edited by all people. Be nice for each person to list handle (some accountability for accuracy) their cpu batch, and volts needed for 4, 4.1, 4.2, etc. and get some idea of how these scale. Too much work for one person, especially one with a new toy.

Post #1885 is a good pic of measure point on board. With beta 16.b04 uguru is real close to what my DMM reads. When uguru reads 1.32v to 1.34v my DMM reads 1.34v. I just wish abit would fix the damn bios. No doubt they have had access to engineering samples of wolfdale for quite some time. Good luck.
My chip is incredibely cool. I see some members on water at 60c+ low vcore :confused:
I'm at 50-51c loaded 4ghz 1.36v with a tuniq @ 800rpm in a lowcfm/silent case
Even at 1.45v, I barely hit 58-60c MAX
Uguru reports my temps as 33c idle and 50c loaded. Core temp on the other hand reports 51c idle 68c loaded. Thats a 17c spread on both but I think core temp is off because even at default vcore 1.1v core temp reports 48c idle. When I touch the base of my Thermalright it is barely warm while under orthos load.
you could start a spreadsheet on google docs, and link to it in the OP. like
FPO
BATCH
VID.... etc
then when everyones data is voluntarily put into the spreadsheet, 1 user at a time collaboratively, you could sort by any column like a database, and see which versions or mobo combinations are best with the e8400
