so you can get E0 e8400 in bulgaria, but we cant get them in the usa? how do they run? i had an e8600 and wasnt impressed, and went back to an e8500 for now.Quote:

Can you tell us exactly what you did? Post all settings and testing method for stability. Thanks in advance.Quote:

What kind of cooling are you using? Please tell me is phase or ln2 or dice.
My chip might be dying now. Orthos doesn't want to run very long.
i had this chip for burning only so i didn't care about degrade so i just put some volt o see how the cpu will react
for cooling i had water on the Cpu & board
For stability Prime95 with "Round Off Checking" on
so the first week he could do
3.8Ghz with 1.35
4.3Ghz with 1.55
4.6Ghz with 1.65V
now a week after runing for 24/7 @ 4.6 with 1.65V stable
thenhe needed for
3.8Ghz 1.4Volt
4.3Ghz 1.8
and for more Mhz only with the 1.9 and more Vcore
i didn't mined to lower the speed or the Voltage as now the cpu is for Rma and i'am waiting one 8600
the degrade from what i found with this chip is getting more and more aggressive if you run at Higher Voltages and only on high Cpu loads
i was running my first E8500 for 3 months @ 4.2 with 1.4V and no degrade...
it's funny that most of those degradations happen in Greece :D
it's the hardware that came inside Greece not the users
many people Confirms that the hardware is third grade
we had two 8880Gtx one from Greece and on from Usa
gues what the one from Greece when we where benching with dice she needed just one drop of water
and she died and the other from USA was covered with water and she was benching like crazy
the insulation was the same
So far, what batch is the best for e84/e85? I'm waiting for the new e0 will be available widely in my country.
Q814 and Higher seems to Clock Better...
Whats the word on the 8400 batch q808a? Mine requires alot of core voltage for a stable overclock.
A decent chip...mine does 4ghz @ 1.23Vcore, still w8'ing for u're results :cool:Quote:

Should I be comfortable with that voltage? I run this 24/7 and its very stable. Should I worry about degredation? The temps never get that high in prime, occt, or orthos. I usually never see any higher than 53c. I lapped my processor and am using a zerotherm nirvana with mx-2.
Why did you RMA it?Quote:
i didn't mined to lower the speed or the Voltage as now the cpu is for Rma and i'am waiting one 8600
I get 3.6ghz with 1.2 volts and 3.8ghz with 1.25 volts.
Seems like too high volts/temps to me for stable oc.
i get 4GHz stable with 1.32 volts and still keep it at 44 idle and 53 load with a true 120Quote:

btw- I idle around high 20's according to real temp, and orthos usually puts me around 40 degrees.
thanks a ton for any help!
set the lower Voltages on your motherboard and set your fsb @ 400 Mhz
99% you wont need to do anything more and your cpu will work @ 3600Mhz
use prime small fft's for 5-8hours to see if you are stable
PS my rma is done but the game me on Q9450 :(
I see alot of results like that but I think its my batch. Ive seen people that need high voltage for a moderate oc like mine. Ive seen good results with this chip on my board too, although vdroop is huge. Im at 1.32v under load. If I try to get to 4ghz I would need over 1.4v. I have my vterm at 1.31 and cpugtl at 66% of my vterm and my nbgtl is at 67% of my vterm.Quote:

boot @ 400 Fsb and you are done
The E8600 I just sold off did 4.0 (8x500) with 1.208-1.216. :) It was a good chip but ran a little warm.
What was wrong with it?Quote:

EDIT: so I know what vcore is, and im guessing DDR voltage=DRAM voltage, but whats VTT? thx!
it was not clocking with normal voltages stable at all the first core was giving me a Fetal error in prime even at stock speed/voltage ;)Quote:

Looks promising. I'll be all over these bad boys if they can hit clocks/volts like that consistently. I can't bring myself to buy a quad core being that no program I use will ever use the extra cores. Where are these chips coming from, Germany?Quote:
Look what I got today- I was wery suprised I havent expected E0
I brought my E8400 down to 3.915Ghz. I will keep it at 1.55v and see if it continues to degrade. It is 15+ hours Orthos stable.
One thing that makes me wonder is that I ran Intel Burn Test the other week. My chip went up to 77 degrees. I can't rule out wether that had something to do with the degradation that I experienced.
At the moment I'm at 4350mhz at 1.344-1.35V Stable
Haha I lol at your V's. Mine gets 4ghz @ 1.19v and it's rated 1.25v when it ran stock :rofl:

very nice, where did you purchase it?
Are these E0 Stepping E8400 available in US?
Pretty confusing. My E8400 has progressively gotten worse. used to need 1.36v at 4.01Ghz and now it needs 1.38 for 3.91.
Pissed is not the word! :(
They'll start shipping today.Quote:

What's your real opinion about it?
FPO Q807A367
How do you tell E0 stepping from C0 one? I've got brand-new E8500, pack date 8/7/08, Q822 batch. And why exactly E0 batch better than C0? :D
Does the S-spec number on the side say SLAPK or SLB9K? SLB9K is the E0 stepping....
SLB9K, so I guess it is E0 stepping... Now I need to a pick a mobo to oc this baby with :) I've got some decent DDR2 memory, any suggestions on what mobo to use with this? I'm coming off 975 chipset, nice one but old :)
Asus p5q - no vdroop. That'll be my next board.Quote:

Weird thing, the E0 e8500 hangs on boot with this Fry's crappy ECS mobo but the C0 e8400 works just fine... is the cpu dead? or just not supported by the motherboard?
EDIT: NM, bios didn't support E0s out of the box. I've updated the bios, so it's all good now :D So it's warning to those who are buying new E0 stepping cpus along with new mobos - mobos may not support them out of the box ;) ECS came out with new bios only a month ago, maybe others did it much earlier than that...
hi
here is another sucker for you guys E8400 Q818A254.this one not even go to 4Ghz stayable with OCCT no matter what volts i put in.i also used auto
in bios but no go. in windows it freezes and reboots.as you guys konws 9*445 setting is very easy for MB and RAM to handle.any body else with this batch and p5k dlx MB whats your experience.i know most of these suckers make you very frustrated when you overclock them.
Hey which Fry's? Fountain Valley?Quote:

Hey, I am somewhat new to overclocking. However, I understand how it works and what settings to change and I have done a bit in the past, but nothing serious. I would still call myself a noob, do to lack of experience.
Any help would be appreciated as I am having trouble getting stable at anything other then default settings.
Computer stats:
cpu - e8500
mobo- p5e3 premium wifi@n - lots of options for overclocking
ram - ocz Reaper ddr3 12800, 1600mhz - This overclocks well i believe. 7-7-7-20
hdd - 4x250gig @ raid10
cpu cooler - ocz vindicator, works alright, could be better.
psu - corsair hx520w psu, upgrading to 620w when i go CF
Video - 4850 with accelero s1 attached will get a second one later.
All I want is a 4.1ghz oc cpu, and ram at default or higher speeds and rock solid/stable.
Whats a good starting point?
Edit: Batch # Q817A226
Hiredgoon just run the volts up to 1.40 volts and see what ya get in cpu speed
and then you can deside what you will settle for ;)
( or go to the max volts that makes ya happy)
i thought 1.4v was starting to get a bit high on just air cooling?Quote:

called INTEL again this afternoon. they still havent received my RMA yet. so thats a plus for me..
will the vid be the same with the E0 stepping? or has it increase a little..
question? with the new E0 stepping what actually makes it so much easier to OC these bad boys? im not no genious or anything like that so the answer might just blow me away...lmao
OMG, that's a nice chip, i love E0 Stepping :shocked:..u're temps are verry good, 60degres are not high...what cooler are u using?Quote:

Wow, E0 is looking NICE!
And i thought my chip was good.. :p:
just talked with INTEL. theyt got my old CPU and the new one has been mailed out . so by friday i should have it up and running. they couldnt tell me which stepping i got. all they know is its the newest one they have in stock.?????so with wishfull thinking it is the E0
Read all the pages of this post, and any other posts you like, all the info you need is here. 4000-4100MHZ is easily doable on an E8500. And hang out at XSF, you will become an addict like the rest of us:DQuote:

I would say MX-2.
I have had good luck with mx-2. Thanks for the replies guys. I reseated the heatsinks on my board and when I reseated the heatsink on my cpu I used a little too much. I lapped the processor and heatsink so I have to use a drop or two. I usually put a drop or two and spread it thinly with a credit card (seems to work well).
Don't have a p5e3 but in general:Quote:

If there is a voltage dampener option in bios, use it.
Lock pci-e to 100.
Make sure that your RAM can do do 450 stable at 1:1 first b4 overclocking the ram or trying a higher ram:cpu ratio(try 8 x 450 first)
Check with realtemp that your load temps don't exceed 60c.
Good luck.:up:
hiredgoon... if you have tried every possible combo on your board and still not stable
then like it or not you have a dud chip... dud mobo.. funky ram.... or your parts dont like to play togather it happens
small shop here and have seen the wierdest things a setup wouldnt work change out mobo and all is fine... use that same mobo in another build ( all different parts ) and again all is fine !
it happens probbly a weak trace on mobo or something silly like that
good luck

Right thread :up:
15 minutes isn't exactly rock stable for sure though - my northbridge would cause a crash at 18 minutes until i got active NB cooling.
Great work but you need probably 1 hr to make the list ;)
Here's my 8400 C0 in it's 24/7 crunching groove (Q815A182). Pretty cheap setup overall. P35-DS3L, 2x2gb patriot, asus eah3870, sunbeam core contact/panaflo 114cfm, pcp&c 610. Pretty much flies through the work units. Very stable, error free machine. I don't think I'll be buying any more of the sunbeam heatsinks. It comes with a decent fan controller but the stock fan is pretty weak and the mounting system is really a pain. If I buy any more cheap hsf it'll probably be xigmatek, either s1283 or s1284. Not a whole lot of difference between those two as far as I can tell.

Any Temp Showing software (RealTemp,CoreTemp,...) displays a 5-7°C difference between cores of my CPU.
First When I assembled on my system, there where 3-4°C difference,
Later in 2-3 Weeks I got 7-8°C difference (measured with RealTemp 2.7 and while I replaced the Default Silicon Patch with new Silver Silicon Grease)
and Now I got 4-5°C difference between the cores (using RealTemp 2.75Beta)
in Idle Mode(2267MHz);
SpeedStep and C1E and C2 State Enabled I got: Core0/Core1=40°C/45°C @950rpm CPU Fan Speed
I want to know why are these differences?
Ok thanks guys, I will try out some more stuff. Would you RMA the cpu first or the MOBO? CPU being bought locally at a store, vs MOBO being an online purchase. God I hate to RMA.
I think the best OC I had was 8x500, but that failed the stress test pretty fast. While that could boot and run for a bit, 8x450 was not stable LOL!
OH BOY, the last day to return the CPU is tomorrow, I got to think quick, shal I do it ?
Loonym
is those temps under load? if not i see why your not impressed with that cooler.
still a nice OC on that DS3L i can only get 4.1ghz stable on my P35-DS3R
my new E8400 is out for delivery. i should have it this afternoon. hopen its a E0.
i know its early for the E0 steppings but is there any known batch # that is better than another?
if the CPU is local do it first. wont take as long. look for the E0 stepping when getting the new one,take it back replace it and try your other stuff with it then. if still the same results send out the mobo.Quote:

God I hate RMA.
are you sure your mem is compatible with your board? i had some crucial ballistix 1066(singlesided) that was junk and not compatable with my GA-P35-DS3R. it wouldnt let me do anything. crucial sent me some doublesided 16chip ddr2 800 and im rockin with them..
Thank you guys.
I updated the post with the processor batch.
I know 15min prime isn't garantee that it is stable (in fact thread 1 stopped after 30 mins).
I know it isn't heat problems, the volts are sweet low and I have a lot of fans cooling the silent pipe (both the VRM and NB sides).
I'm still tuning the system, I raised the volts one tad to run 3DMark. Looks stable now :)
Next, tune the memory (these GSkill PI run up to 1200 on 2,15v).
And then prepare for ludicrous speed FSB :rofl:
cincyrob, yeah load temps but I didn't get those temps until I put the 114cfm panaflo on. That alone would be ok because I normally like to use a big fan but man, the mount is really a pain. When I first saw the sunbeam core contact freezer it really grabbed my interest as a cheap TRUE alternative partly because of the unique mounting but after trying it I really dislike the mount system. It cools great but I'm not sure it's worth the hassle. If I ever swap it to another board I'll grab a bolt-thru kit and make it work.
Loonym: I'm using a Xigmatek HDT on a DS3L and it covers up to 4.5ghz ok on an E0 e8500 (see above posts).
However, the DS3L will fail Prime or Orthos after 18min because the NB fails due to heat for anything over 4.3ghz..
I put on old DFI lanparty NB fan over the DS3L NB with doublesided tape and it's stable for me now ;).
ok guys i got my CPU. its not the E0 stepping but its a newer model. here is the batch # how did i do? what shouldi expect out of it?
Batch# Q817A151
151 huh got me some rum..lol

This is my friends E8400 E0 under SS. The only limit is fu*** FSB wall. Because it can do almost 5ghz at 1.45V:D
What's the diff between MX-2 and Artic Silver 5?
I used the 5 i had lying around. Should i get some MX2 instead?
Ive gotten better temps with mx-2 (nothing huge) but I only tried AC5 once or twice and yes I did let it break in. The big difference is that mx-2 is not electriclly conductive and there is no breakin period. That makes it great for mainboards and graphics cards.
ok guys. i got the new CPU in. my temps are great compared to the old CPU. its not the E0 stepping but im happy.
i put it in fired it up to make sure its running then took it to 3.6ghz. running OCCT now. all's well so far.
i know you want me to take it to 4+ghz..lol i will in a couple days dont wanna toast it before i get to use it any..lol
here is some shots of everest,occt,cpuz.oh yea i have all settings at auto. so i havent done anything to it to get it to run 3.6ghz...
trust me now that i dont have the temps to worry about 4+ghz is on the way. hopefully i can run every day at 4.0ghz thats truely my goal.
under load here
http://i72.photobucket.com/albums/i1...rob/occt-1.png
at idle.
http://i72.photobucket.com/albums/i1...ep35c-ds3r.png
yes core 0 has a stuck sensor when idleing.
so should i rely on core 1 when idleing? can i fix a stuck sensor? or should i RMA this one casue of that and try for a E0???lmao
Maybe its me but around 60c seems hot to me. My E4400 @ 3.4GHz 1.55v has a load temp the same as your E8400 :p I would of thought your CPU would load around 50c tops with that vcore.
