No. If you do that you probably won't have anyway to screw the damn thing together again. Yours are way smaller then mine. Mine come out of the motherboard about 3-4mm's. Your's are like only 0.5mm or flush with the mobo.Quote:

looks like its settled on 37 core 1 and 45 core 0 idle temps.. not bad from where it was and i still have a nb fan to add a second heatsink fan and another 3 case fans on my 690!! that should help out some
still think ill order me a true again or maybe that new ocz one everyone is ravning about or the newest version of the xig.. hmmm if i can shave off another couple deg ill be super happy with a 4.2 24/7 oc..
OMG! I dropped 11C!!! I love this Xigmatek. :shocked::shocked::up::up:
http://ocidb.com/albums/userpics/101...od_12cdrop.JPG
Edit: Re-ran prime95, same room temp, and now it's showing 67-68C per core for some reason. It still dropped by 5-6C but oh well... Hell if i know WTF is happening here but that's the last time i'm taking it apart this month. :)
well your temps are still better than mine im at 4.2 at 67c or so.. your at 4.3 same temps. what did you do to get the lower temps..maybe i can try again doing something else now.. but right now im not going over 67-68 max temps..i would still like it to be lower. im thinking the xigmatek just starts off really well but gets saturated and then cant keep the lower temps we both started with the first time we ran prime. im stinking a different cooler and a lapping job are in order for the cpu
I just shaved off those things from the backplate and remounted.
Dunno why it stayed at 60C the first time and now it jumped again at 67. I think the Heatsink is saturated too and can't really keep up with these low VID cpu's and "highish" voltage. It's just too much for AIR IMO or maybe it's just because it has only 6 heatpipes
I don't think a lapped TRUE would offer any improvements to be honest but if you get one post back though. If it offers improvements over this i'm gonna get one also.
im thinking about that new ocz one that tested better than the xig and the true in the tests here by spawne (i think that who tested them)
even still at 4.2 still running stable still running orthos 67-68 on air imo is not bad. my x9000 in my laptop gets mid 70's not overclocked and its a 45nm and thats stock
I can't get the OCZ in this country otherwise i would've gone for it also. It has 1 heatpipe more then the Xig and in reviews i saw just a 1-2C advantage. Not really worth it but hey... it's fun :)Quote:

I'm not sure how to go about fixing that. I get the feeling if I can do something about it, I will be able to do a stable 4200 Mhz OC with this chip. Here are the settings I used.
Vcore - 1.36 (real) (Set to 1.32 in BIOS)
NB - 1.504
SB - 1.65
CPU VTT - 1.26
Ram 5-5-5-18, 2.1 Volts
PCIE Clock - 105 Mhz
CPU VID Drop - disabled.
All CPU Special functions except multi processing - off
Strap - 400/800 strap (But tried and failed on 333/667 too)
Any suggestions on solving this particular problem? or is it just a lost cause?
ya use it 24/7 and ya shiped from canadaQuote:

only have to worry about the blue waterblocks no the unit itself
it's gotten my cpu up to 4.5 so far ( not stable yet ) with same temps as 4.0 :D
since both e8500 and e8400 are so cheap now, which can achieve an overall higher clock? are the current new e8500 bad batches? they are sub $200. i ask this because on average, an e2160 can OC higher than e2180 even though it starts off with a lower clock.
heres a shot at 526 fsb on 8 multi with a load and with the house ac turned OFF for you CoolIt fans

yes my board has .04 v droop
I make my own custom backplates that put those stock ones to shame, I'll have to post some pics when I finish my new ones.
turn down the vcore back to around 1.20-1.21 then turn the special add to disabled and add 106.xx to 107.xx till you find the 1.3x spot (if you set it to 1.20 vcore then set it to mid to high 106.xx for the voltage you need but ill bet doing it this way you'll need a bit less than you are using now i know i did) you need this for me was MUCH MORE STABLE than trying to shove 1.35 up the cpu's throat lolQuote:

imo that is a lot of volts on the nb im running 4.2 for my oc right now with only 1.37 on the nb and it passes orthos for 6 hours now...
imo leave the sb alone 1.51 i believe
i have the the cpu vid drop set to enabled and for now try the strap at auto till you get stable.. i fought a huge battle with this mobo and cpu and so far im winning the fight im at 4.2 with 1.328 voltage and 6 hours stable on air with temps maxing at about 67-68c during orthos and prime..
oh and imo i leave the c1e turned on so that when im not using the 100% it will back down for me and not run so hige working GREAT so far for me
philbrown....please do the 1 thing a CoolIt unit needs is a good backplat imo
btw over 6hours stable at 4.2 orthos with 1.328 volts on air temps 67-68c ... im letting it run a while longer..
zfactor that is exellent for that voltage !
temps are on the edge tho imo 70*c for penryns is scary :eek:
man the old daze 70*c was the norm :rofl:
yeah but remember this is with both cores at 100% how often will they run that way in real world use. ill bet the temps will prob stay at or around 60 or less everyday max.. know what i mean?? so far i have yet to see them go over 70 yet running orthos.... yeah i feel pretty good about it i just wish the temps were like my last e8500 they were almost 10c lower at idle and 5-7 less at max...
also i do see the vcore drop to 1.316 during orthos so ill bet i could squeeze even a bit more but i think ill be content unless imm doing a all out bench run.. so if i added another small bit ill bet i could get to 4.3...
ya eye never see that kinda load everyday :up:
i have to say once i have learned patience with this mobo it really is a nice board...
what do most people see with their e8500 at idle on both cores?? im seeing 37 core 1 and 42-45 core 0 (has to be something wrong with it im gonna lap it tomm to see if that will help but it refuses to drop below 42 no matter what i have done)
and everyone had me worried about the q817 chips lol... ^^^^^^^^ but next step is to get temps down a bit then start to up the fsb and drop the multi to see if i can get to near 500 with the same overall clocks..
Dropped the NB voltage to 1.28v. Still no problems. Good temps at 1.32v this time around :)
http://ocidb.com/albums/userpics/101...1_29v_4300.JPG
still dont see how its stable like that.. wow.. with those temps on air.. thats insane
Passed to E8500, batch Q816A678. First found FSB @ 450 MHz. CPU FSB @ 1.2V, and nForce SPP @ 1.4V. Did a pencil mod. So far at 1.232V load stable at 3,6 GHz (8x450). My BIOS voltage is 1.23750V, Windows idle 1.224V. Passed 12 hours of Prime.
My max temperatures were 52-53 C.
I think you'd better put the windows closer together in a square and crop that part out of your screenshot.Quote:

Nice CPU btw! :up:
So guys i can't understand is it normal to have different temperatures of the cores ? Or difference coming from somewere such as cooler or something ? My E8400 has 5 - 10C difference @ idle :confused: Same situation @ 100% load, most of the time difference is around 5 - 6C... I also saw some other people with same differencies and also saw that on E8500 has no difference... I think about to buy E8500, but to keep this E8400 and i am curious did i had something to do about the temps...
mine is that way at idle but at full load the temps are basically the same sounds like it could be the heatsink or maybe the heat spreader on the cpu may be uneven?? or check that the sink is sitting flat and flush. i use a razor blade to check for flatness
^very impressive. Will there be E0 revisions on the other E8xxx chips?
think we iwlll have an interesting summer after all :) will add the E8600 to the list then too :)
Csktl1 : plz full batch nr
Time to give some more money to Intel pretty soon - getting at least 1 e8600.
they are appearing in the shops lists and are retailing around 210-220 euro's so pretty good deal...
It's because of the image resizing. You can enlarge and get full resolution.Quote:

does that make a difference. any better any worse?
If you are not planning on ocing then I don't think it's worth it, no....but if you are OCing then it looks like the E0 revision is very good. Just look at his clock, 4.25ghz with 1.256v? Not seen that on a C0 revision.
Well we have seen from the rare E8600's that they clock nicely over 4ghz, most wolfies till now needed a big jump in Vcore over 4ghz... the E8600's seem to go nicely up to 4.5Ghz now... think the OC'ing potential for high speeds is better... though who will notice a jump from 4ghz to 4.5Ghz in games ?

with Nehalem right around the corner im sure the E8600 will also drop in price drasticly like the E84/8500's have now.
kinda off topic here. but seeing i dont game do i really need one of the top end HD type gpu's? other than to say i have one???lol
has anyone seen any of the E8600 in the US yet?

I got a E8500 Q814A156 and it just completed 32m at 1.22v. Awesome batch. cant wait for LN2
I have E8500 Q816A678, VID 1.2250. At 1.376V it's running at 4,037 GHz, (1.38750V in BIOS). My maximum temperatures are 63-62 C, usually around 59-60 C while priming. Is it safe to keep it under this voltage for 24/7?
Indeed, a friend and I just got e8500s from 2 different suppliers, both Q814As with 1.225vid. We were lookin at your crazy VID and being very jealous.Quote:

Does anybody knows something more about OC-ing E8400 from Q817? Some people said, that can't reach 4 GHz on acceptable Vcore, but no one shows screens. I can' believe that this week is so terrible.
Guys, I said at the page before that E8600's coming in August (10th) and the price will be 200$. E0 stepping is on every pre-relase Intel CPU and it's always better then retail one's.
in germany is the retail E8600 available and its a great clocker :D
this is with watercooling (water @ ~34°C+)
http://www.abload.de/img/4.5ghz-0174r.png
wow i may be buying another chip after all...
Here's a review of the E8600 and they get some nice clocks out of it.
http://www.xbitlabs.com/articles/cpu...duo-e8600.html
They also mention the E8400 - E0 coming out so once the present inventory is gone we'll probably start seeing them at an even better price point than the E8600.
so then the E0 is the better of the 2 then??? im gonna have to really consider the E8600... 4.2ghz 24/7 everday im likeing... still at low volts.

If the E0 E8400 clocks anything like the early results I'm seeing from the E8600, then getting a nice 4.2 GHz on low volts shouldn't be a problem.
I'll probably give them a pass, since I've got 4.2GHz on 1.36v and I'm pretty happy with my chip.
Still... the E8600 at 10X is pretty sweet. :D
to get 4.0ghz for me i need 1.3625v max to get it stable. i don t wanna run it that high justfor 4.0ghz. i think i might be able to use 1.350v but not sure if it would be stable. but i think my mobo and mem might have something to do with it.
ok i see i can get the E8600 here in the US now. but its nothing like what everyone is saying. its only 2.5ghz and L2 cache is only 3mb... here is a link to it???wth is this??

same here had 2 of em and both needed more than 1.3650 to do 3.8
hmm mine is a e8500 q817 im at 4.2 with only 1.328volts i know its not a e8400 but i heard the same about the e8500 as the e8400 you have so im not sure but mine im sure could go higher yet
what other settings do you have??Quote:

not much more to set with this mobo
ahh yeah sorry i didnt look at your sig. ill bet with more setting you prob could tweak it more. isnt there some secret pages in that bios or am i thinking of a different mobo??
E8400 Q815A077 on stock vcore (CPU-Z says it bounces between 1.184 and 1.200, can't make change stick due to F4 BIOS glitch on EP35-DS3L) at 9x370 (3.33GHz) seems good so far on small FFT p95
DDR2-800 running at 740 to stay 1:1, PCI-e locked to 100MHz, C1E and EIST disabled, stock cooler with fan on max and 60*C Prime95 according to RealTemp 2.60
I'll try 375 later, the first time I tried it I had my RAM at 900MHz at the same time and one core failed prime95 (large FFT, max heat test with some RAM) in about 5 minutes, but it could've been the RAM that was unstable.
Ambient is around 30*C
Thanks. That version of coretemp shows my VID as 1.1125V. So which is correct? :confused:Quote:

I'm very busy trying to overclock my new system. And I have to admit I had a pretty hard time on getting some decent overclock. I just read this page and saw some complains about the Q817 batch. Well, I guess I'm unlucky then cause my CPU has batch number Q817A240 (pack date 4-6-2008) with a VID of 1.25V (in Everest).
I have the following results at this moment which seem te be stable. However I have to admit that I'm still trying to find some better settings and need to finetune. I would like you to shed some light on my current settings and maybe give some advise which would be much appreciated.
CPU: 4Ghz (9x445 @ 1.43725V) (RealTemp, Idle: 40 & 36; Load: 54 & 50)
RAM: 1780 @ 1.94V (8-8-8-26-2T; specs are 7-6-6-24-1T)
NB: 1.54V
VTT: 1.3V
DRAM static read control: disabled
DRAM dynamic write control: disabled
CPU spread spectrum: disabled
PCIE spread spectrum: disabled
Load line calibration: performance (this setting seems to prevent much of Vdroop according to CPU-z)
All other settings are on auto
In my opinion the Vcore and NB are bit high. Moreover I'm not sure what the highest acceptable values are for these settings. Anybody has some guidelines? But when I compare my settings with other E8400 owners I get owned big time although my settings need some finetuning. Is this only due to a bad CPU batch? Any help would be nice.
Intels rated max for the E8400 is 1.3625v so anything over that they say may degrade the lifespan of the cpu. With all the reports of degradation around, I'd stay under that.
Lower the vNB and keep retesting to see what happens, all boards are different.
Thanks for your fast reply. I don't know how serious these degradation reports are but if the temps are alright I don't really mind setting a higher voltage. Considering the life span of a CPU would be 10 years or so and with higher voltage it at least still have a life span of 3 years. Of course I would like it to be as low as possible, so I will fine tune and try your advise but 1.36 is a no-go I'm affraid when aiming at 4Ghz with mine CPU. And after reading the E8600 article I'm thinking of buying one by the end of this year.Quote:

you have basicly the same mobo as me. except i have a few more goodies onboard. you should be able to get 3.6ghz with ease.Quote:

if your mem was at 900mhz you had to have your freq at 450mhz 450x2=900
and 450freq on the cpu will give you a nice 4.05ghz oc... thats why it failed on you... try it at 400 with those setting i suggested and you will like what you get.... very easy 3.6ghz...i will tell ya now with these type gigabyte boards you/i have it runs warmer than others with different/better boards
EDIT:
doing a little more OC. i got it up to 4.1ghz i think its stable so far. im running orthos now and all is well.
here is my question.
i set my vcore up to 1.3975v(higher than the max 1.3625v) but with the vdrop im only getting 1.33v is this normal/OK... which shouldi be trying to get to run stable? what im getting with the vdrop or what the actual setting is i have set at now?i think with the vdrop i would have to take the actual setting up to 1.4250v or some where in that range to get it running at the 1.3625v.. ill do a screen shot of orthos and everything else once orthos has bee nrunning for 20 mins or so.
oh yea my temps right now with orthos runnin is 74-76c. 30deg away from the TJ max of 105c or 95c which ever you tend to go buy.
I don't understand anymore. What's the maximum allowed voltage? Some say under 1.4V, some under 1.3625V (at least say's so on Intel site). Come on guys, will you finally agree all together on maximum allowed voltage? I mean, we all know maximum allowed temprature is 72 C, but every few pages I can see different opinions about maximum allowed volotage...Quote:

Thanks for the reply. So with 1.376V and maximum temperatures under prime of 63 C I have no problems...Quote:

this is what i have as of now with the vcore set to 1.4000v in the bios.:shrug:
http://i72.photobucket.com/albums/i1...crob/41ghz.png
i only get these 70's temps when running these stress test. under normal load of dvd-rebuilder and such i only hit like 66-68c is this ok too?
Yeah... Gigabyte's vdrop like hell... specially their cheaper models.Quote:

just watch your temps though to much higher with vcore and your may get to hot.. i would not push to much farther myself. maybe just a small bit..also maybe you should try a different cooler. that one is ok but for the oc you are wanting imo you need a better cooler
You're thinking of the right motherboard, but the settings aren't really useful for overclocking CPUs, as far as I can remember. I have the same motherboard, but I'm stuck at 3.85 Ghz with 1.41 V due to an amazingly crappy CPU.Quote:

As you can see on the previous page I have set my Vcore to 1.4325V in bios right now. With Vdroop taking into account CPU-z gives me 1.41V and that with Load Line Calibration on performance in P5E3-Premium bios. I have to admit that this LLC feature helped me getting the Vcore a bit more stable and gave me less Vdroop.
In the end I think temps are the most important reference for the danger of frying your CPU. Moreover if your on water you can accept a bit higher voltages IMO. Unless you want to be absolutely save and tend to use your current CPU for the upcoming 10 years or so, then I would obey Intel specs. However, I don't think anyone on this forum is planning to use his/her CPU for 10 years that's why I mainly focus on temps. According to RealTemp my temps under Orthos load are 54 and 49 with Vcore on 1.4325V in bios.
no my bios dont have anything for the vdrop. not htat i know of. i will try bumping it up one setting at a time now.. orthos failed again at about the same time. 17mins 45sec.
im gonna bump it up to 1.4120v and try and get it closer to 1.3625v. i have C1E disabled. that makes since to have it enabled. like you said theres no need to have it running that high just to surf the net and send emails.
ive just been reading the article from here about the better coolers. im thinking of getting the OCZ Vendetta 2. that looks like a very sweet cooler.
as for your DFI mobo... all them different settings in bios has kept me from trying one... seems like alot to go through in them bios.... i need to learn a bit more before i tackle something like that...lol
ok going to change vcore again.
InCore
do you see anythign different when you hit ctrl & f1? i dont see anything different that allows me to do anything?
i found this thread here(named wrong) it deals with some OC'ing stuff with the E8600
http://www.xtremesystems.org/forums/...ighlight=E8600
nah its not as hard as you think. took me maybe a week of reading and testing but im got it pretty good now.. i just need a bit of help fine tuning now im hoping praz or someone like rgone or anyone here will help me with. the dfi is soooo nice as far as bios goes. there is so many options to help you around every corner. for instance i could not boot at all at any vcore over 1.23??? yeah odd i know but using the special add vid feature i could at anything i want now. then with even using add vid anything over 4.1 (and i mean anything at all even 10mhz) it refused even to post. i got a quick on then off.. so i used the boot up speed feature and set that for -200 so it will boot for me now at 4.0 then go up to 4.2 when its okay to do so... things like that are pretty sweet imo
and yeah GET a better cooler at 76c i would not go nuts if you see your temps go up more
So my E8400 is 8+ hours Prime95 small FFT stable at 3.33GHz (9x370) around 58-60C on stock cooler.
CPU-Z seems to suggest my core voltage is fluctuating between 1.168 and 1.184, I'm using a GA-EP35-DS3L with F4 bios, which is known to have issues with voltage settings. In the bios it says the default CPU voltage is 1.225 (and I haven't touched the setting) so I'm confused about the CPU-Z report, which I guess indicates vdrop from reading the last few posts. I hope when I eventually flash it to F5 and voltage settings stick, I can bump it up to 1.200
sorry yeah i mistyped.. i didnt mean to mislead anyone i was talking about vdroop
Ok, then my vdrop is 0.025v (idle 1.200v vs bios 1.225v) and my vdroop is 0.016v (1.184v load)
Is this bad? What voltage should my E8400 have on load with stock cooler by default?
well it dont look like it is ment for me to run this E8400 at 4.1ghz or higher. stays stable about 40 mins at max. im not gonna take the volts up any higher than i have. ive backed it back down to 3.6ghz. until i get a better board i doubt i try 4.0ghz again on this one.
i am gonna get a better cooler. the TRUE120 looks like a good/awsome cooler but from what ive seen you need to lap it to get it good and flat. along with buying another 120mm fan it would be well over $100. to much for me for a cooler. i like the OCZ Vendetta 2. i might get one of them this weekend.
i can say this is def nice to run 24/7 at 4.2... things are just ridiculously fast now lol...
At 9x370 (RAM 1:1 at 740mhz) I am stable for 10 hours prime95. At 9x375 (RAM auto at 900mhz) I am unstable. Do you think it was because of the RAM not being 1:1 and going too high, and I should try again to go above 370 fsb?
Is 3.33GHz a pretty bad oc?
i may have missed it but what is your vid cincyrob
what are the rest of your settings? are you running your timing set to auto?? i can not run my sticks on auto the board if have doesnt like it. i set them manually and it opened up a whole new amount of fsb for me ...i wish i knew more about the giga's you guys are running but they seems to pretty basic in the settings the offer you..Quote:

running orthos right now on the 3.6ghz i set it back to. temps are only 66c under load right now. thats on both cores.
also my mem is in manual set at 4-4-4-12 and the voltage control is all set to auto. and my vcore now is 1.180v
hamtard
something dont add up if you have your freq @ 9x375 that wont put your ram at 900mhz only at 750mhz.
I am running my RAM timings on auto, I don't know what keys to press to unlock manual (ctrl+something I think) is that a problem? What should I run my RAM at?Quote:

I've made it longer than my last 375fsb attempt in prime95 so far, so I'm hoping my problem was the "auto" RAM speed setting way overclocking my RAM, since that is fixed now.Quote:

when in your bios. just under where you set your freq it will say something like memory control???? it will have boc that you can highlite it will say auto. arrow to it then hit enter it will let you in the setting and change it to manual.Quote:

DDR2 800, my sig has most of my info, what timings should I run, the ones listed on the package, or change them?Quote:
