Wow temperatures are rising in here! :p: :D
I am sure there was just a language/translation problem, no need to take it personally guys, we are all here doing the same thing. :toast:

WOOT!! In the 9 second bracket.
1.60 set in BIOS
nice going it seems the e8400/8500 likes the p5k motherboard as cordovader who posted earlier also had good results , whats the fpo/batch code of your chip
Well, I went back to the store and exchanged my CPU for another one, Q746A503 is my # and it seems to be much better...
4014mhz @ 1.27v VS 4014mhz @ 1.44v running orthos on it now and it has made it past the 10 minute mark. I'll be curious to see where I can get with this chip.
I want to run it around the 4ghz mark 24/7 so this seems to be much more suitable.
My 8400 is:

People are saying ignore coretemps and look at CPU temp, what program can be used? (Most accurate?)
Here is my 1meg Pi at 4860mhz.:D
@ flesheatinvirus
Nice clocks there. Your RAM is doing some pretty good clocks there,congrats !
@frzzy and flesheatinvirus
I don't understand how I could get a 09.891s time at 4682MHz and you guys are getting just 09.578s at an incredible 4860MHz. You both should be in the 8 second bracket i would think. What version of Spi are you running? I have noticed that I have to run Pi twice to get a good number. The first is always higher. I have no idea why. Incredible clocks BTW guys, very well done.
It's just normal on intels. :)
A quick test with my E8400:
http://www.abload.de/img/1mfzjs.jpg
I guess I have to up my volts. :shrug: Great job guys. :up: I can't believe we can get in the 9 seconds on water. Never thought i'd see it from an X86. An amazing chip for sure.
Maxwolfie: CPUID Hardware Monitor and SpeedFan are two free programs which show the cpu temp in Windows, although SpeedFan seems a bit buggy with the Wolfdales.
I was wondering why I can't break the 10 sec. barrier in SuperPi1M. I have the same or better settings that some of the others, but 10.2 sec is the best I can do? More FSB?? Some have broke 10 sec. with 502FSB with the same ram timings as mine? Is it my crummy DDR2-667 ram or do I need water cooling??
wow, a lot of 1.6v out here lol... :( i hope our suicide runs dont massacre our procs, mobos and mems lol. The max I did was 1.55v (1.536v vdroop) for my 4.5ghz run.
So just so we are all on the same page. It is confirmed that the core temps are not working... Mine is idling at 34 C and core 1 says 60C and core 2 says 43. Also the two cores dont flucuate much. Ive tried reseating my water block 4 times. Changed thermal paste twice. And even flipped the water block around. Made no differnece at all and did not help lower the gap between the two core temps. So I am pretty sure that these are not worth looking at, which it seems the rest of this thread is in agreement with. I just wanted to make sure.
I've started trying to overclock this with the 680i and am having a hell of a time. It seems I have a fsb hole. At 1800 it wont post no matter the multiplier. At 1900 I can run orthos, but seems to be freezing after 2-8 minutes. I am going to do more tests, but this is as far as I got with day 1. Anyone else have any luck with the 680i.
For those concerned with high voltages and degredation here is a link to the E8000 series data sheet. Section 2 covers electrical specifications. ftp://download.intel.com/design/proc...s/31873201.pdf
There's also a supplementary document / spec update with a list of errata.
Many of the errors mention workarounds that can be addressed in updates to bioses. Others will be addressed in a new stepping.
Pain in the butt for board and bios engineers, but would be very grateful if they did the fixes that they can.
Well the microcode update would have to be added into the bios and new bios prepared and released no? I do remember there being a bunch of issues with 65nm C2D and I think there was a microcode update for those.
If you look at the list of errata there are a lot of "bios workaround" mentions. For example the most recent addition - AW51 from 02/01/2008.

Yes. But this is relative a little work. Besides, writing BIOSes is the main job of the BIOS engineers, no? :)
Of cause. But all those erratas are not relevant to 24/7 use. It may be interesting to OS writers or those, who is programming some specific applications. It is applied to Penryn erratas as well. Really critical errata (such Yorkfield instability on older boards) may delay CPU intro.Quote:
I do remember there being a bunch of issues with 65nm C2D and I think there was a microcode update for those.
Yes but there are no explanation how exactly it is implemented. I suppose the most BIOS fixes are implemented through microcode update. And, possible, it was already done.Quote:

I guess we'll just have to wait and see if there are updates that fix some things or not. Aside from errata I think there may be need for lower voltage settings in some bioses to meet the specs..
Here is my Aquamark3 result at 4850mhz with single 8800 Ultra.:D
Just built my new machine this weekend: E8400, Tuniq Tower 120, Gigabyte P35-DS3L, 4GB DDR2-800 SuperTalent, EVGA 8800GT, 150GB RaptorX - All these bought new. I'm using my old Antec Sonata (the original) case, and OCZ 520W PSU (still under warranty).
The new machine was built so I can play DX10 games, as well as be able to run it 24x7 as a web/app server, so it has to be quiet. My previous rig had 6 fans and was very noisy (X-Alien case, opteron 165 @2.7GHz, Asus A8N-SLI, 2GB DDR-400, XFX 7800GTX OC, 150GB Raptor, same OCZ-520W PSU.
Anyway, without wasting too much time, I overclocked it to 400MHz FSB, CPU @9x400=3600 MHz, 1.325 V. Temps are 32C idle, 59 load - with the Tuniq Tower 120 CPU fan at the lowest setting (1000 RPM). If I disconnect the case fan (a single 120mm rear exhaust), the temps increase by 8-10 C.
I'm currently shopping for quieter case fans, and possibly a VGA cooler.
I haven't overclocked the video card yet, so 3DMark06 score is around 11.5K.
I'm very impressed with the Tuniq cooler. I even left it overnight with CPU and case fans both disconnected, and it still managed to keep the CPU below 60C (idle, closed case).
rofl -ive had to have an arguement with scan.co.uk to get my cpu rma'd after my psu blew up as apparently (quote the chap) "ive never had to rma a cpu and these have been out for 2 weeks so i doubt they will die"
Bit confused with temps.
http://img401.imageshack.us/img401/1...dfanmo9.th.jpg
This is at 4.23Ghz - 1.416v REAL * 1.372v LOAD
What im confused about is, WHY am I getting a bunch of different readings on different apps, example, core temp reads the 2 cores @ 65/65C LOAD, speedfan is reading CORE @ 55C and CPU @ 45C
What the fook is WHAT ??
I am not worried about my temps, I have nothing crazy on vcore and a good cooler - the TU120 EX, I just wanna know what the hell is what!
:(
have you tried everest or uguru?
I have an early version of everest but it does not recognise my CPU and the latest version just says I need a key - but the early version says the same CPU temp as speedfan.
http://img264.imageshack.us/img264/5...restwe0.th.jpg
EDIT: OH WAIT< it seems speedfan is STUCK on 54 CORE temp.
I find this part very interesting: Our temps problems?:
AW30. Programming the Digital Thermal Sensor (DTS) Threshold May Cause
Unexpected Thermal Interrupts
Problem: Software can enable DTS thermal interrupts by programming the thermal
threshold and setting the respective thermal interrupt enable bit. When
programming DTS value, the previous DTS threshold may be crossed. This
will generate an unexpected thermal interrupt.
Implication: Software may observe an unexpected thermal interrupt occur after
reprogramming the thermal threshold.
Workaround: In the ACPI/OS implement a workaround by temporarily disabling the DTS
threshold interrupt before updating the DTS threshold value.
Status: For the steppings affected, see the Summary Tables of Changes.
& this the part i found interesting - Plan: No Fix :rofl:

Is it true that the max FSBv u may apply for these chips is 1.15v? cause I have my FSBv @ 1.40 now, so it worries me abit oO
That is the official Intel spec but nobody around here ever listens to stuff like that. :D
http://download.intel.com/design/pro...s/31873201.pdf
2.6 Voltage and Current Specification pg.17
The Absolute Maximum for FSBv is 1.45 volts but anything beyond 1.155 volts is beyond spec.
Gaah! Can't Understand why both the U.S. versions of this cooler (Xigmatek and Kingwin) come with the push-pin mounts! They don't provide enough pressure!
http://c1.neweggimages.com/NeweggIma...233-003-11.jpg
Yes, I'm gonna try 4GHz and even more, after I get my new case fans. My current case fan is too loud, so I turned it off, and the CPU temps at 3.6GHz are already above 60C (load), so I don't want to go higher until I have a good case fan in there. Not to mention that 8800GT is idling at 75C (not overclocked), which seems way too high. Damn Nvidia and their sub-par stock cooling.
Alright, so with the new E8400 and the 16B09 bios here's what I'm getting.
This is exactly what I was hoping would happen with a cpu exchange, lower volts and 4ghz stable while closed up in my desk on air cooling.
I know I'm not in the same ballpark as some of the other extreme numbers, but I have slow RAM that doesn't like much more then 480FSB and really, 4ghz is good enough for me. I included my settings from uGuru if anyone was curious.

I got an E8200, FPO Q746A513, pack date 01/17/08
It does 8*500MHz @ 1.336V :) On air of course, max temp is 63 celsius under prime95 small fft's test!
Ive got a Q750A032 E8400 which seems very poor so far.
Failed prime after 20mins @ 4Ghz with 1.45v :(
Will start again with lower volts and play about with the GTL volts a bit.
How high is it advisable/safe to go to with NB volts to test max fsb?
Good news for Abit IP35-PRO owners.The 16B09 bios reduces the .1+ voltage drop from bios setting to windows on the E8400.Now it takes less volts in bios to achive same clocks for me.
Currently testing my e8400 on board in sig (650i). Ran ORTHOS at stock voltage and core 1 failed within a minute. Bumped up a bit (1.14) and left to run overnight and failed after 2 hours or so. Core Temp shows my VID as 1.0375. I'm trying to get stock speed stable before I oc, so far at 1.16v and my NB at 1.45 to be safe. Temps are great so far, 48/53 cores and 34 cpu in SPeedfan 4.34 beta 38. This is on water in sig.
Did you already encounter problems of FSB Wall to 440MHz (FSB) with E8500?
I do not manage to exceed the 440 stable :/
I am astonished.
According to you that could be because of the bios or the motherboard?
it is not very commen that those chips are fsb walled @ 440, I think there is a setting u overlooked....
GTLREF? You guys are speaking another language to me with your Intel chipsets.
The only other setting I have is FSB/VTT voltage, and I havent even played with that yet.
The temp info issue with these new Wolfdales is certainly a concern though Im running a modded single water loop just for my chip which keeps things rather chilly in my test rack but everyone building a new rig should keep a close eye on things and hopefully we can find a resolution to this matter. These Wolfdales really crank for the money despite there lack of accurate temp measurement and for the money are still the best bang for the buck price/performance wise.:D
Here are my results at 9x450 after 17 hours small FFTs
http://img341.imageshack.us/img341/4...nch1je8.th.jpg
Nice keep pushing it;)
I got the board aswell:), I find 333strap works way better, i got probs with 400 strap beyond 450fsb to post, could be a curten divider causing it as with 333strap 1:1 @ high fsb the board got a hard time to post, but using other divider it will post without a prob with acceptable "low volts", right now I am priming 468fsb with 1.20FSBv and 1.49NBv , clock twister strong, both dram static read control/ transaction booster disabled, cpu PLL: 1.50v/ Sbv/ SB1.5: 1.05/1.50, CPU/NB GTL: 0.63x/0.67x, u might use these settings and adjust it accordingly.
as for your RAM, disable transaction booster, often the culprit when going high FSB, u might even need to relax to 1.
Working on 400x9 right now, is 1.33 normal for this speed? Seems kinda high. Also had to raise NB to 1.5v or I cant even get into bios. remains to be seen how 650i will do with this chip.
3.6ghz @ 1.33v, seems abit to much for a wolfy at that speed, with those u can most likely get yourself up to 4.0ghz or more( ofc some cant), think it is your board being the culprit:X or a setting you might have overlooked
No vmods yet. I do run bios Vc regulation disabled which actually helps stability beyond a certain point on my Wolf as compared to my Quad which seemed to require it. I can run a 333 strap right up to about 535 or so then the bus gets moody and 400 is needed. Decent board
I raised the FSB/VTT voltage to 6% and bumped the vcore to 1.41, only droops to 1.39. Dont know which one was the fix, but I'm gonna dial in 445x9 and see how little I can run on. In XP now at 3825. I forgot that 680i has a FSB hole at 400, so maybe 650i has the same problem. Even at this vcore I havent cracked 60 on the cores and much more than 40c load cpu. Weird, at 3600 it was priming fine until I opened a browser, then would lock up.
I haven't had time to test out yet; even though, it's been rock solid playing GRAW2. I finally came around to testing this in a warm environment (32c) just to be sure I'm ready for summer.
Here's a screenie of it priming while I type this reply. Will post settings as soon as I establish it's stable. :up:
I decided on them after I had stayed under the 1.30v range, When I was at 1.29 and would run orthos it would fail right away. I checked my GTLREF and found it to be at 69/67 so I started working my way down. Once I found that orthos could run for at least 10 minutes, I moved them each down 3% more and that's where I ended up at.
It's been stable since I started that run but I've been trying out some different OSes so I haven't been letting it run for more then 5 hours at a run yet..
@Zucker2k
Your screeny is showing 4300 in CPUID and CPU-z and 4554 in Orthos?
http://www.xtremesystems.org/forums/...1&d=1202179606
I'm very confused again :)
Hey Sound, it's because Orthos sees the multiplier as 9x instead of 8.5x.
D-Oh!
Goes to prove I confuse easily :)
Thanks mrcape!
@soundx98: what's your VTT on that run?
On Maximus Formula still testing...
9x500 with strap 333 PL=8 is very easy PL=7 needs more juice (Disabled 0)
cpu is on air and i have not raised any of CPU PLL = 1.5, FSB Termination Voltage = 1.2 although monitoring reads PLL = 1.6 (overvoltage) FSBT 1.12 (undervoltage because of 8400, with E6750 1.2 in bios resulted 1.21 on monitoring)
Still air .
Ok, this oc seems stable enough at 32c ambient on water...will test for 4.4Ghz soon.

Team Xtreem PC2 6400 @ 4-4-4-12-3-30, 2.3v
Will post settings later, gotta take a peek in the bios setup first :D
Went on to test some more with my E8500 and had a nice find. :)
I was determined to find the cpu's max at reasonable voltage (max 1.6V) so i started off with 1.55V and 9.5x 475= 4500MHz.
From there on i would work my way up with SetFSB but i could not even reach 4.6GHz. :shrug:
I gave it some more Vcore but again, over 4580 i was greeted by the dreaded BSOD.
I tried more Vdimm and some more voltage options in bios without succes.
Because this was so frustrating i wanted to know how much stability i really had at 4.5GHz.
Suprise...
http://img.photobucket.com/albums/v6...rthos45GHz.jpg
I stopped it after 6 minutes because the temps scared the h3ll out of me but if it can run Orthos small ftt's i should easily get 1M done at at least 4.6GHz, no?
So, in a desperate attempt i just booted into windows at 485x 9.5= 4.6GHz and it just booted into windows without trouble.
I could run 1M without a hassle and got somewhere real close to the 10 sec. barrier.
Again i tried to work my way up with SetFSB but after +2MHz FSB it bluescreened again. :confused:
Conclusion: SetFSB does not work well with this board/bios/cpu or maybe i should have raised CPUPLL voltage?
To cut a long story short, i booted straight into windows at 4.7GHz and 1.6V.
I even managed to pull off a nice 1M run:
http://img.photobucket.com/albums/v6...ots/1M9812.jpg
I think it should be able to run some 3D mark at 4.6GHz, but that's something for another day. :)
Didn't want voltage to be an issue (because of heat) so I upped core voltage a wee bit. After the 13-hour run I went into bios and cut down on a juice and so far looking good. I should be comfortable with those voltages under water, especially since these wolfies seem to handle voltages better than peeps previously thought; or would have you believe. :stick:

Just started clocking mine, been waiting 1½ weeks for this due to mobo problems. Using ABIT IP35 Pro now and I'm very pleased with it so far. Temps on E8400 is off though like seems to be normal with these, doesn't really change almost anything during idle and load and like 10C temp difference between the cores etc. But heh the air that is pushed from Tuniq Tower 120 is like cold to the touch during Orthos too.

Now it is not.
I advise all of you not to push them beyond 1.3.

Wow great chip u got there, I needed 1.31v (load) to be orthos stable at 4GHz.
Yeah, and its living up to the hype. I want to get this Wolfdale in a game rig, but I still have to play with it a bit more. :D
Looks like 4.2ghz is going to about the limit on air. Big bump on the voltage to get another 100mhz out of it for 4.2ghz.
I'm using OCCT like you because its really hammers the CPU harder in a shorter amount of time than Prime.

http://img240.imageshack.us/img240/6...2025sp1.th.jpg
I might break out my water gear, but while that might help my temps, its not going to stop the CPU voltage from staggering around like a drunk. :(
My other e8400 chip needs approx 1.36 to be 4ghz stable.
I'm trying to learn more about what is hurting these new E8x00 processors. Can you still run Prime at 4050 MHz and how much voltage do you need now?
What was the highest voltage you ever saw in CPU-Z when testing? Did you ever go over 1.45 volts even briefly?
Part of the problem might be the FSB Termination voltage. The Intel spec for these new CPUs is only 1.1 volts +/- 5% so the max is 1.155v. Some of the older boards can't get down this low even at the lowest bios setting. What is your setting for this?
I mentioned this in another thread but it needs to be said again. Here's what the Intel datasheet says about core voltage:
2.6.1 Absolute Maximum and Minimum Ratings
Table 3 specifies absolute maximum and minimum ratings only and lie outside the functional limits of the processor. Within functional operation limits, functionality and long-term reliability can be expected. At conditions outside functional operation condition limits, but within absolute maximum and minimum ratings,
Intel defines Absolute Maximum core voltage for these new 45nm chips as 1.45 volts. That number is not necessarily a safe 24/7 voltage. At 1.45 volts you are "outside the functional limits of the processor" and "neither functionality nor long-term reliability can be expected."
Wondering if I need to up my PCIe frequency since I have been prime stable for about 2 weeks at 4280 on my e8400, maximus formula. I have seen others set this to 110 or so. I have it at 100. Is there any difference or reason to have it set to 110??
1.34 vcore
I think I've found my 24/7 config now. :) Might up it 1 or 2 FSB still if I can do so without upping voltages but should be around this. Wasn't expecting the board to handle 8x multi at such settings but seems like I underestimated it. Need to find my max clocks on 8800GT too, but I'm easily at 14k+ 3DMark06 24/7 config, maybe even 14.5k.
http://img233.imageshack.us/img233/8...00finalja0.jpg
RPGWiZaRD, that is pretty much my 24/7 too - 4.1ghz at around the same vcore (1.39v)
Any higher seems to require more vcore, and I'm not prepared to go above 1.4v.
:)
