Nice what is the VID/ and batch?

btw I ques u made a typo @ the Title

[danmoody]

the batch number is #q740a523
version#: e27439-001
pack date 12/27/07
s-spec: SLAPL

which one is vid?

[Infa]

If you open Coretemp, and then Look in the middle, it says VID: blabla

there are your VID, and VID are the cpu's default voltage.

regards.

thank you the VID: 1.1125v

[Truckchase!]

Here's my start:

vCore in BIOS: 1.375 (minimize vDroop enabled)
FSB Term: 1.2
NB: 1.4
PLL: 1.6
vMEM: 2.15
Cooling: Water, DD TDX block (yeah I need a new one)

FPO/BATCH# Q745A372
Pack Date 12/20/07

Don't have coretemp running right now (vista x64) to get vid

Haven't taken it past 1.375 yet, but it seems to scale 50 Mhz for every .250v since 1.3v, so I'm kinda getting diminishing returns. I'm sure I could comfortably surpass 4.2Ghz with halfway decent voltage, but I'm not sure what I want to run 24/7 vCore as of yet...

[disruptfam]

the vid is also on the box the of the proc yeah?

[deadlock7]

No that's the max volts..

[dinos22]

hi guys nice CPUs for both of you

i did some testing with E8500 CPUs recently

yeah ill do some testing it doesn't seem to like more than 480 thou

I better be posting in this thread soon.

Reserved for my hopes to have one at the start of febuary.

[turtletrax]

Looks like mine is a dog. I tried 4.05 ghz upto 1.35v and would not boot, Winblows would get half loaded and give IRQ_Less_than_Equal. Could be my DFI and me missing a setting but I DK.

Drat.

I've I can do 4GHz stable like above, I will be satisfied :toast:

[-n7-]

These are impressive.

Seems like over 4 GHz you gotta pour in the vcore...

But ~ 4 GHz with decent vcore for 24/7 is sweet :D

I can't see myself going back to duals though...like the quad too much.

[RPGWiZaRD]

I want at least a 4.2GHz 24/7 clock out of the E8400 I'll pick up or I'm disappointed. :D 4GHz is too easy and normal for Wolfdale. :p:

How long is minimum orthos run (with smsll ffts) to be considered stable?

2 hours !

Actually orthos is considered kinda buggy. Better run original prime v255 or later:

Custom test 1024-4096 would be good for 6+ hours

I'll start down that path D, honestly I've never qualified my board for it's maxFSB so I've got some work to do to get a qualified answer....

[Zucker2k]

Here's mine, Q745A356

http://valid.x86-secret.com/show_oc.php?id=301016 Using watercooling in my sig. With wofdales, cpu temps are not as much of a difference maker as they used to be. I don't even keep an eye on mine when overclocking anymore.

[turtletrax]

What Vcore is that at Zucker?

I have mine at 4.5Ghz 1.4Vcore right now, but with the DFI it seems I have to spend more time on the GTL's to get that balanced first.

[ghost_recon88]

Hey everyone, I'm originally from ocforums.com so don't hate too much :shrug:

Anyways, I'm having a problem getting my retail E8400 prime stable @ 4.5GHz. Heres my original thread on ocforums, http://www.ocforums.com/showthread.php?t=544212

My current setup consists of a lapped E8400 (batch Q746A381), a lapped Thermalright Ultra 120 Extreme, 4GB of G-Skill DDR2-8000, Abit IP35-E (BIOS 14) and a Corsair HX620 PSU.

Basically is that the best BIOS for overclocking Wolfdales with? I have my NB @ 1.41 volts, SB @ 1.6, CPU VTT @ 1.23, and vcore @ 1.58actual after vdroop (according to CPU-Z). That voltage seems kinda high for only 4.5GHz, so I'm wondering if theres some other voltage I'm not increasing enough. I haven't seen many (or any at all) Wolfdale results on the IP35-E, so I don't exactly know what I'm shooting for. I know my RAM is capable of running 530MHz FSB, and I took my board that high on my old E6300.

[Motley]

Whoa there nelly, what are you complaining about? Not getting over 4.5GHz on an E8400...

You should be happy with that, thats a very nice OC.:welcome:

icy, that is awesome! :shocked:
I may have to start hunting for an e8400!

[ghost_recon88]

Whoa there nelly, what are you complaining about? Not getting over 4.5GHz on an E8400...

Thanks for the welcome :clap:

Aww man, I was hoping for at least 4600MHz. Think those voltages I have are kinda high?

[Motley]

Thanks for the welcome :clap:

Aww man, I was hoping for at least 4600MHz. Think those voltages I have are kinda high?

You're at 1.58v? For testing is OK. But 24/7 I would not go over 1.45v.

[ghost_recon88]

You're at 1.58v? For testing is OK. But 24/7 I would not go over 1.45v.

Ok, I'll keep that in mind for doing my 24/7 overclock. A lot of people here seem to have a ton of $ to throw away on LN2 cooling and other kind of exotic coolers eh'?

Well it is XtremeSystems so I wouldn't say it's really out of place! Hmm, no one has an E8500 so far? Was really hopping to see how that compares to E8400 overclocking!

[Retrolock]

wow! these 8400's will finally realize my dreams of reaching 4ghz! (and then some) keep on posting guys!

eva2000 got the E8500 @ 4896Mhz with 1.6v. Not sure what cooling, but I think thats on Air.

I just ordered the E8500, should have it here by the weekend. I hope to get 4.6-4.8GHz on 1.45-1.5v. As soon as EVGA comes out with the 680i BIOS update this week!

Nice, but that is your ss shot. I bet my chip could do more than that on an ss.

[ghost_recon88]

Is Core Temp 0.96.1 reading the Wolfdales temps correctly? or is it still off? Appears its 5c off on the T.j. Max temp.

[aznsniper911]

^That was a nice thread but too bad he stopped after a while! It seems they want to push this thread for the E8400/E8500 overclocks, only time will tell!

[Counter CS]

Ppl i can´t find anywhere a store with those E8400 in stock.

Here in Portugal they said that those CPU was added to next month...
WTF :confused: Is this true ? :shrug:

[sambir]

Could a e8400 max air stable overclock beat a q6600 @ 3.6Ghz in games? In 3dmark06 it cant but that doesn't mean that it's not faster then a q6600 if im right. Here in The Netherlands the cpu is for sale on only one shop. e8400 is 270 euro haha scammers...Other shops are all out of stock.

Yep, most games don't take a full advantage of 4 cores yet

[doakh]

Well I really notice any significant performance improvement while running applications if I upgrade from an e6600 to e8400? The price seems very reasonable and I am very tempted.

Has anyone been able to get the e8400 going with an ASUS p5n32-e SLI plus? If so please let me know what you did or what BIOS version you're using.

Hey everyone, I'm originally from ocforums.com so don't hate too much :shrug:

Anyways, I'm having a problem getting my retail E8400 prime stable @ 4.5GHz. Heres my original thread on ocforums, http://www.ocforums.com/showthread.php?t=544212

My current setup consists of a lapped E8400 (batch Q746A381), a lapped Thermalright Ultra 120 Extreme, 4GB of G-Skill DDR2-8000, Abit IP35-E (BIOS 14) and a Corsair HX620 PSU.

Basically is that the best BIOS for overclocking Wolfdales with? I have my NB @ 1.41 volts, SB @ 1.6, CPU VTT @ 1.23, and vcore @ 1.58actual after vdroop (according to CPU-Z). That voltage seems kinda high for only 4.5GHz, so I'm wondering if theres some other voltage I'm not increasing enough. I haven't seen many (or any at all) Wolfdale results on the IP35-E, so I don't exactly know what I'm shooting for. I know my RAM is capable of running 530MHz FSB, and I took my board that high on my old E6300.

play about with the CPU PLL volts a bit, more NB might help also.

Nice clock otherwise :up:

[Shampoo]

Baaaaah, I think I have a dud.

I have a separate thread going here and in a P5N-E SLI thread at anandtech forums.

Batch: Q740A523
Packdate: 12/20/07.

I'm priming right now 450x9 @ 1.360-1.376vcore, according to cpu-z.

Failed orthos after 20mins when I had it a couple ticks down from the current vcore setting in the bios.

I'm hitting temps of Core0:57, Core1:58 with a Thermalright Ultra 120 Extreme with a Vantec Stealth 120mm fan in a P182 case, but currently being run on its side and open front and side panels.

Kinda toasty. I wish I could've gotten a good chip for once!! Like (sorry forgot name) watery?

I thought I'd get lucky and get one that could stay under 50 degrees at over 4GHz, but nooooooooo, I'm struggling to get it stable at 4GHz with high voltage. Bah!!!!!

I've got another one of these of the same batch sitting at the office for a client's system, which will never see overclocking. I wonder if I should test that sucker out first.

I don't think it will do much better since it's from the same batch.

I should be happy nonetheless since it wasn't officially confirmed my 650i sli chipset could handle these processors, or my motherboard for that matter, Asus P5N-E SLI. (bios 0803)

[Truckchase!]

I didnt know there was more to it then just making the thread sorry for being a noob

Dan do you want to do it? We could see if we could get some admin help and such.....

On an on-topic note, mine did a full 24 hr prime @ 4130 @ 1.375v (BIOS set). Stepping info and such is above.

Did anyone notice that vDroop on the wolfdale chips seems to be significantly more prevalent on the same boards? I had .2v difference between my set bios vCore and my reported vCore on my Conroe, where as the diff with the Wolfdale is like .4v.

[Shampoo]

Okay I'm up to 1.408v on the cpu.

Orthos failed at a previous attempt after 48mins.

I'm losing hope.

Could be the board of course, since P5N-E SLI boards don't have official bios for these cpus yet.

I couldn't get my E6400 or E6420 stable at 450 FSB, so maybe it IS the board.

Thinking about picking up a P5K-E anyways.

Okay I've given up and am going to either try another cpu or motherboard.

P5N-E SLI won't run stable @ 450*9 with ample amounts of voltage to the northbridge and cpu.

Could just be mine or could be because no official bios yet. ?

Edit:: Should've done this before...going to check stability at default settings of 3GHz, with default voltage and 1333MHz FSB. See if it's the board and bios.

I guess I have to wait for a bios release or just go out and pick up a P5K-E, because I just ran stock settings and it failed orthos and froze my system within a few seconds (30seconds to 1min).

Try 445 x 9, Shampoo. My old E8400 wouldn't boot into Windows at 450FSB with 1.55v, but at 445 it was happy as a clam at lower voltage. I have the exaxt same batch Q740 12/20/07 packdate as you. I took my old one back today as I had bad core readings and this new one is about bang on. I have just booted into Windows at 450 x 9, but it is not stable. Not sure any other week would be any better without superior cooling.

i have the same exact batch code and pack date. mine does 450 x 9 @ 1.275v. low volts for 4ghz, but once you cross that threshold, the voltage requirements jump dramatically. for 475 x 9 i need 1.375v. 500 x 9 needs more than 1.45v as i cant boot into windows with those settings.

[Kryckter]

I have one from NewEgg.

Batch # Q745A356

I can get 450 x 9 with 1.35 vCore. (1.375 in Bios)

Anymore than that and it crashes, no matter the vCore, But I am pretty sure that is my memory holding it back. I have 4 gig (2 x 2gig) G.Skill 1006. It is at 900 mhz. Anymore than 950 mhz on the memory and the system crashes constantly. This is on a P5K Deluxe Board.

[dengyong]

I talked to a online rep and got $25 off, so I payed $199.99 shipped :p:

How's that work ?

[Shampoo]

Well I've decided to give back the cpu to my boss and use it in a client's system.

I'm gonna wait on this. My system just isn't stable at default settings either, so bios update is awaiting.

As for this batch? I don't know, but it looks like a lot of people are having to pump a lot of voltage into their E8400s to get above 4GHz or even 4GHz stable.

I will wait on this.

is there really that much performance variance from different batches at this point? where do you buy these that they let you inspect the box prior? seems like ordering online is just not worth it if there's that much oc success relying on the batch :(

your just expecting too much.

4.5 ghz on air, isnt gonna be stable, or easy. even with these.

sure, it can be done. mine can do almost 4.8 on air so far.
but not much is stable past 4.2-4.3ish.
atleast, not to the point where I am willing to push more Vcore into these.

I am still learning the ins and outs of my CPU here.
it OC's insanely, but getting stable is the hard part so far.
these are very jittery little processors.
alittle voltage off, and you will be unstable. yet they boot at almost any speed you set them at.

my P5W mobo feels so dated now. i actually traded a P5B-D for this because i was more interested in CrossFire performance than a high FSB.

http://img.photobucket.com/albums/v620/Z3us/SuperPifactory/1M9953.jpg

Unfortunately it took a lot of voltage, above 1.6V didn't help much though.

My cpu is on watercooling but gets even warmer than my E6600 B2.

[SIOUX]

I just want people to know that i have been running an E8400ES chip for 4 months now. And prime would fail this chip at 4ghz 1.45v after 11 minutes. no matter what voltage was set, it was just not stable at 4ghz Prime. BUT...i can play all newer game for a hole day without a crash at 4ghz 1.38v, wich would fail prime instantly. Actely i never had a crash at 4 ghz 1.38v no matter what i did. :)

So i think we must look into this. i think i remember that this happend with some AMD chips in the past??anybody remember that? it would also fail prime, but be rock stable for 24/7 use?? :)

Also i see these new E8400 retails doing 4700mhz on air, and 5ghz on Vapo LS. now my ES would only go to 4200mhz stable, but it did the same as newer chips on VAPO (about 5ghz) :)

[Praz]

Unfortunately I don't believe there is no one benchmark that will show stability 100%. I saw the same thing on the ICFX3200. Could run any stress test program there was with 3dMark looping at the same time for hours on end. But Prime would fail in under 3 hours.

I think the days of Prime stability ended quite a while ago. Not only is it no longer the definitive test of stability any longer but its extremely hard on the board and components to constantly be hammered like that.

That's exactly what happened to me and my E6750. I could do anything at 3760Mhz at 1.57v. It would pass 1 hour of OCCT, run any game for hours without any glitches, compiled hundreds of programs, including the kernel (on my linux OS) and my max uptime was about 3 weeks or so. Prime/Orthos would fail after 40 minutes though. The hell with Prime/orthos as far as i'm concerned :up:

[bonzo_catalin]

If you mean Prime95 , Orthos or OCCT , i do not know , i never kept my cpu other than default with C1E enable for 24/7, and i have a few ( E6600ES , E6600 , E2160 , E2140 , E6850 ) . I go higher as i can for SPI 1MB and 3DMarks .

...And prime would fail this chip at 4ghz 1.45v after 11 minutes. no matter what voltage was set, it was just not stable at 4ghz Prime. BUT...i can play all newer game for a hole day without a crash at 4ghz 1.38v, wich would fail prime instantly. Actely i never had a crash at 4 ghz 1.38v no matter what i did. :)

So i think we must look into this. i think i remember that this happend with some AMD chips in the past??anybody remember that? it would also fail prime, but be rock stable for 24/7 use?? :)

Also i see these new E8400 retails doing 4700mhz on air, and 5ghz on Vapo LS. now my ES would only go to 4200mhz stable, but it did the same as newer chips on VAPO (about 5ghz) :)


Sioux... I can affirm that multi instances of prime95 would bork my e6400 in a heart beat, but Prime 95_25.3 (worker threads imbedded) and occt would run all day.

I'm being an optimist here... Maybe the programs are the problem? Doesnt seem to make sense... as it stands though, usability trumps priming

Dave could you please give some more info about your 748A cpu regarding clocks-volts required (4ghz and up)? I need to choose between 2 of them...
thanks

Hi mate,

Going by memory, the Q744A needed less voltage than Q748A. But Q748A hit higher FSB and was easier to overclock on P5B-D motherboard.

Had very limited time with them, so I cannot give you anymore useful information than that.

I hope you get a good one.

Appears the X38 boards are handling these chips a lot better than the P35 boards are, at least the voltage necessary to hit certain clocks vs. the voltage necessary on the P35. Looks like I may need ton invest in a new board.

Well I dont think so... It is the Cpu, every cpu is unique, so it differs from voltage requirement, untill some1 test a curten cpu head on head on a P35 and X38 and see, but I doubt it.

What is C-N's formula? :shrug:

Hey, it's just a way to calculate your gtl vs vtt. In a nutshell it's keeping vtt voltage low (1.2v in my case) and setting gtl to around 55 & 58% of vtt. I shouldn't have called it "his formula", but it's something he pointed out in the DFI P35 thread and I kept going back to it when trying to get the right settings.

I think it's too early to count on this thread as evidence of good and bad chips. There are too many variables - mb & bios, stress method, ram, cooling, sensor accuracy, software accuracy, defined stability. I mean, I can boot into windows over 4ghz at crazy low volts but is it stable? Even if you can do SuperPi 32m I'm not so sure.

I think we have similar batch numbers so i'd like to see what you get for results. I also have an X38 P5E that I want to test withn the week to get performance on X38 vs P35 with the same exact chip. Noone seems to have that data that I can find.

Hey, it's just a way to calculate your gtl vs vtt. In a nutshell it's keeping vtt voltage low (1.2v in my case) and setting gtl to around 55 & 58% of vtt.
On the DFI boards the GTL values in and of themselves have no numerical value in reference to the percentage of VTT that is being set. For instance, if a value of 60 is selected for GTL that does not imply that is the percentage of VTT being set nor does that represent a discrete voltage value. The voltage value that will correspond to 60 will change as VTT is changed. At the same time whatever percentage of VTT the value of 60 represents will also change as VTT is changed.

As no accurate measurements have been done when using these processors on DFI boards to assign any type of preferred percentage based on the value selected for GTL is a bit premature.

Interesting. Any insight on why setting VTT low and GTL manually at about 50 - 60% of the VTT set in bios seems to help? It works for me.

[mrcape]

Okay but what is it good for? Stability? I' ve kept those at auto, does changing these values do anything for running lower Vcore?

It seems to have done a lot for stability in my case on the DFI board. Leaving VTT high (like on 65nm) and the GTL at auto I would rarely be able to get in at certain speeds above 4ghz, regardless of vcore. With VTT low, and GTL set manually, I could get in and run stress tests. And as I notched the gtls down from there, the stability got better.

Mine seems kinda hot as well, in core temp 96.1 but moreso at idle end at around 42c. In the bios it reads really cool. I can't imagine it's this hot at idle with low volts like 1.29vcore. Then at blend load it never gets over 59c even up in the 4-4.3ghz range.

I think you missed the point I was trying to make. Run GTL values at whatever works. But at this point in time nobidy knows that the values being set on the DFI boards equate to 50 - 60%. By themselves the numbers have no significant value.

Any1 bought an E8400 from Newegg?

What batch did you get, and results?

[Xvys]

It seems many E8400's have core temp sensors which report incorrect low temperature readings. These false readings are being reported in all software monitoring programs.

I had a E8400 which reported idle temps of 17C in one core and 34C in the other. Under load, the 34C core readings were frozen until it exceeded 34C.
I exchanged that processor a new one, albeit from the exact same batch, but the new cpu more correctly has core temps of 38C/36C (4.0Ghz with 1.34v).

Programs like CoreTemp read the diode right in the cpu, so software updates or bios upgrades will have no effect on these false readings.

Some E8400 purchasers are being told to just ignore these false core readings and instead rely on the "cpu temp" reading, rather than core temps.

Haha you mean stick it in.

I'm wondering - how hard is it to move your mobo, from one case to another, if I'm using a TR.120E? I can probably install tomorrow if I keep my old case, but if I order a new case, I'd have to wait - unless i'm willing to temp it in my old case.

[Xvys]

Those temps seem similar to mine, yenclas. At 4.0GHz (445 x 9) my core temps read 38/36C, with the cpu at 28C. Under Orthos the core temps are 52/56C with the cpu temp at 46C.

I have the Extreme heatsink which may account for 2C extra cooling compared to yours. You also have to take into account your room temperature. In Canada my ambient temp is 22C, while in Spain your ambient temp might be 25C...so you are starting 3C higher and cpu temps will always be 3C higher.

I've got the same symptom - Core temp 42c on both cores at idle on - 500x8 4000Mhz and 1,3vcore. This is the same system that would be reporting about 20c per core at idle with the same volts on an e6600. I re-seated, and have two fat San Ace fans running through it with ambient temps around 12c (window open in MA).

Xvys' explanation helps. I'm wondering if I can trust the load temps and ignore the idle. Didn't somebody say they raised the max temp warning on these to 70c?

As someone posted in another thread, Intel designed these core sensors to read extremley high core temps to throttle down the cpu when overheated. They apparantly were not designed to be used as thermometers or necessarily be accurate at lower temperatures. While some enterprising software designers have brought out programs to read these core sensors, Intel is probably not obligated to ensure their accuracy at low temps. Intel's own Thermal Analysis Tool does not work with the Wolfdale cpus.

This is somewhat of an adventure. I had the latest BIOS from DFI but it would not allow me to disable EIST and the other CPU protection options. I would set vcore, multi, and FSB in bios but only the FSB would hold. When I launched CPUz it would tell me 6x multi and 456FSB. So I flashed to a beta bios found on T-Mod's DFI CD (give that guy a cigar). Now I can run the E8400 without any issues other than the temp discrepency.

My WC system needs a kick in the ass and my memory timings need some work but I will address those next.

Anyhow, here are 2 quick SS. This SMOKES the E6750 it replaced.

0.85V – 1.3625V, so 0.85v is the lowest.

[Mithan]

I figured I would ask you fine people if anybody knows what the average Intel specifications for the E8400 Thermals are under idle and load and the core temp (if its different)?


I've been looking around but all I can find is people talking about their temps, not the actual recommended guidelines.

Hmm board to choose for this cpu seems hard, blook iron looks decent on it, only one p5k ive seen though.

I was wondering why my latencies are so crummy compared to some others here? My system is stable at 4275 MHz, so far.

What do you think is the best, cheapest P35 board for these?

I want to order a E8400 off the egg tomarrow, but i don't want to spend the $200 on a X38 that i had planned.. :(

Would rather have a stacker + P35 :up:

Go for the P35 + stacker because X38 is not much improvement from P35.

[ThatGuy16]

know of a good one $130 or less, 45nm ready out of the box and ready for some overclocking? :toast:

Why does it matter? VID number

[Bail_w]

Why does it matter? VID number

Some people think the lower vid number will overclock better, but actually it does not guarantee anything in overclocking.

[ThatGuy16]

Thanks bail, has or does anyone know for sure if the DS3L or DS3R are 45nm ready out of the box? thats the only thing im worried about because i won't have another 775 cpu to flash bios if it happend to need it :(

These should OC well with 4 sticks of ram and good FSB?

I hate to ask all the questions, but i might be ordering in the morning :up:

Look at the description, it said 45nm ready, but sometimes you do need to flash the bios.

I am not sure if they will overclock well with 4 sticks of ram but with 2 sticks there are plenty of great results.

[Shampoo]

Oh man all these great results and I'm stuck with my Q740A523 taht I can't for the life of me get stable on my P5N-E SLI board.

I know there isn't an official bios yet, but there are some guys on here that have gotten it stable, so I'm willing to give it another go.

One note. I noticed when my system crashes from not being stable with the E8400 instead of your typical black screen of nothing, or just frozen screen, or bluescreen of death, mine is black with yellow text.

The yellow text being to blurred out to read. So it's like a BSOD, but black with yellow text that can't be read.

Anyone else?

I will give this another try tomorrow or something.

Wish a bios would come out for my P5N-E SLI

1.45v is about the max voltage for 24/7 use right?
I have a 746A328 here, going to try it this weekend :up:

thinking of ordering an e8400 and DFI LP LT P35-T2R. good combo? with some tracers? lovin' the results thx:D

[turtletrax]

eaper;2724429']thinking of ordering an e8400 and DFI LP LT P35-T2R. good combo? with some tracers? lovin' the results thx:D

It is a sick board, but like so many DFI products it is allot of work at the begining. I Personally love the board as much, if not more than my Ultra-D, but am having issues with GTL Ref adjustment past 4.3Ghz. I am sure I will get it ironed out.

I would reccomned the T2R to anybody that likes a good challange, if not I would try another board.

[The[R]eaper]

cool:up: . ive read quite a bit on the dfi p35 thread and it seems like a very solid board. im hoping for a 3.6 to 4.0ghz 24/7 with this chip. im kinda new to overclocking but would like to get more into it. thx again.

[elgoog]

anything conclusive on what sort of voltage these chips can handle for 24/7 (similar to ~1.6v being about the maximum acceptable voltage for 65nm chips)

[cadaveca]

I'm saying 1.40v AIR -1.5v WATER.


Anyone popped an IHS on these yet?

You will also be quite pleased with performance per clock compared to your 680i. I had my Quad @ 4Ghz on my 680i and I went to the DFI and beat my 3DMark06 Score by 700 points at 3.85Ghz :rolleyes:

So far 4.0ghz orthos/occt stable @ 1.33v on a P5K... have no idea what all the BIOS voltage options do but I'm learning lol... 4.1ghz will boot but won't pass orthos for longer than 40 seconds :D
Next week the DFI DK P35 should be here... very curious if it makes a difference... at least the layout is better than this P5K...

edit VID is 1.1125v...

Nice:up: ive had bad luck with my 680i's (3 rma'd) thx again will prolly be ordering in the next week or so.:D

[AriciU]

I think 1.43-1.45 is about the max for these chips under the currently available air cooling. I'm keeping it at 1.48v @ 4.3ghz at the moment and one core goes to around 64C in Orthos while the other jumps between 58-61C. I've heard that the max recommended temps. for these was around 65C.

I throwed some Orthos at it @ 1.55v @ ~4500Mhz. Cores jumped straight to 75C and they we're surely gonna get hotter then that, maybe 80C :D

now the final result..

nice with so few Volts for an E8200 :)

I just started to play with this Q748A142 E8400, i think my temp are high, i did try remount but still i idle @ 42c same temp when i tryed to oc some coretemp is wrong i think maybe because om 780 chipset or something... well first try

So you actually have two premium boards to play with? Damn. I'm wondering if should sell my unused IP35-E for the DFI board. I just haven't seen too many IP35-E results, especially with low vcore. But maybe that's cpu-based, not mobo-based.


I would reccomned the T2R to anybody that likes a good challange, if not I would try another board.

I loved tweaking with the Ultra-D, even though my Opteron was kind of a dud lol. I wonder how much I have to gain if I had went for the DFI instead. Hrmm...
