Not a bad chip you got there. Dont forget to post your full batch number if you want to be added to the database. :up:Quote:

Use the "CPU VID Special Add" to increase Vcore.Quote:

EDIT: oops!!! C-N beat me to it.
Is it OK to run E8500 @ 4,037 GHz @ 1.376V (Load), 1.38975V (BIOS) for 24/7. I heard everything under 1.4V is OK. My computer literally works 24/7...
well mine is on its way back to intel.. hopefully ill get something better in return ... report back soon
VERY nice heikis :up: thats gotta be 1 of the best :D
well it failed at 4050mhz. i raised the voltage one step and then it was 9h stable until error :D i will leave it on orthos overnight with some extra voltage. updates tomorrow if lucky :DQuote:

1.45v, 1.45v VTT (you don't want to go over 1.4v on this though), ~100C.
According to Unclewebb's tests, thermal throttling was kicking in around 93-94C
i43 has been doing some research into thermal throttling on his 45nm Quad. Very similar results to my Q6600 and E8400. Thermal throttling usually begins at about 93C but each core is unique.
http://img522.imageshack.us/img522/8...testingsq4.png
In this pic, core0 has just started to thermal throttle while the rest of the cores are all still OK. Prime continued to run fine.
If you're overclocking the smart thing to do is to run these as cool as possible. When overclocking, Prime stability increases the cooler you can run them. I find a maximum of 60C is much better than 90C when over 4000 MHz on my E8400. You'll lose stability long before you'll hurt one though so as long as you're stable there isn't any need to worry about temps.
There have been a lot of features added to RealTemp in the last month so it would be a good idea for anyone using 2.60 or previous versions to upgrade to the latest beta version.

Download, unzip and copy the new RealTemp.exe into your present RealTemp folder.

According to a IR thermometer I "borrowed" from work, my temps are actually closer to 58 under load. With that in mind and the VID special add trick from earlier in this thread, I think i'm good to go for a higher OC than 4000 MHz. Will keep posted
My E8500 Q814A081 on a 680i-A2 @ 4ghz 1.30v.....temps are 10c lower with realtemp.
Attachment 82262
how are yall getting your systems bootable with 1.3v core and lower? .... i cant even get it to boot anything at 4GHz with anything less than like 1.36 ... and yet i see like 1.2 and all sorts of crazy low v cores ....
@C-N
when it says "Thermal Specification: 72.4°C" is that the max temp you can run at and be safe? or what ...

The annoying thing is we are really all just guessing at the temps our CPU's are running at as just about every monitoring app tells it different.

@ AriciU
Thanks for the info. But what does VTT actually mean? Is that de voltage for thermal throttling or what?
@ C-N
Thanks man, that was the page I was looking for on the intel site but couldn't find it anymore. Even after typing some search string on their website. Thanks anyway.

here is mine ...P95 stable for 8 something hours ... just the max temp it got up to 67C is kinda high i think ... but it idles at 44C
@ReverendMaynard
dang 1.5V ... you going to run it 24/7 with that much juice?
I'm curious. Have you tried running it stable with lower Vcore yet? 1.36 just seems a bit high for 4000 Mhz on these chips. I'd be really interested to see how low you can take your Vcore and keep it stable at that speed.Quote:

im running e8400 batch Q815A181 what kinda volts do you think i should be able to boot up with?
@zlo
TRUE120 extreme
Hmm...those temps seem pretty high for such a good cooler. Is the cooler flat? I know that I had to lap mine (it's now in a secondary rig, keeping an E4500 super-cool).
not sure as to how flat it is .... i guess im going to have to look ...
what should i be getting on a stock 3GHz temps then? any ideas ...
Depends a lot on what your ambient temps are I guess, but in a 80 F room (not sure what that is in C) mine is running about 36-40 idle and 58-60 under load. But that's at 4000 MhzQuote:

so far its lookin like 1.31V BIOS and 1.29 CPU-z is non stable and about 1.33V BIOS and 1.31V CPU-z is about the lowest i think i can get ... ill keep running some tests and see ...
So far, anybody tested E0 stepping for E8400 or E8500?
could you please post you bios settings and revision as i am unable to get my 8500 stable above 475fsb on my maximus extremeQuote:

What i have to do to go over 3600MHz with E8400 stable ? I try everything but without success :confused: Max voltage i tried is about 1,39v. My CPU need 1,3 volt to run at 3,6GHz stable... I cant even think about the volts needed by this CPU to run at 4 GHz :eek: Maybe i had most sh1t E8400 in the world with wall at 3,6...
@ Zeus
I will, thanks for the link.
what volts are you running your ram at... and what is your ram rated for?Quote:

have you tried bumping up your NB volts just a smidge ... like .1 or so ... and see if that gets your anywhere?
I thing NB volts is not a problem i run it @ 1,28v... As i say there is no position in the BIOS that i do not try to tweak but with no luck... I can run this board at 539 FSB but everytime i need to calculate to be sure i not go over 3600 - 3650 MHz :( I saw most of the people can run 4GHz or more witch i want too but im still unhappy...Quote:

It's benchable of course, but I testing yet
Ok. So my E8400 is stable at 4000 Mhz on 1.26 Vcore. I'm having trouble going over 4000 though. The problem is that I can't seem to stabilize a 4200 Mhz overclock on any voltage up to and including 1.31 Vcore. The other issue I'm having is that no matter what setting I change in the bios, whether it be the VID or the VID special add, the voltage won't go above 1.31 until I hit a spot at around 1.34 Vcore. WHen I got it to finally boot at 1.34 and tried to run stress tests, I got BSOD within a few minutes. Any suggestions? Also posted this on the DFI x48 page as well.
Here are the settings I was usiing for 4200 Mhz
Vcore - 1.34 - (CPU VID @ 1.2375 + VID Special add @ about 108.2%)
CPU VTT 1.2
NB volts - 1.405
SB Volts - 1.65
VDIMM 2.1
Ram timings - 5-5-5-18
A lot of e8400's can't hit 4.2ghz at all unless you go to extreme cooling and vcore. I have 2 great e8400's and 4.1ghz requires 1.32, 4.2ghz requires 1.37ghz to be orthos stable. My 3rd e8400 can't get above 4.05ghz stable not matter what volts on air, and my e8400es hits a ceiling at 3.9ghz orthos stable again no matter what volts.Quote:

Such a shame, I thought my chip had real potential to get to at least 4200 on air.
I have a q807 and q813 e8500 that max out on air 100% stable at 4200mhz. Like lagunax said, 4200 for an e8400 on air isn't real common. 4000mhz is real common. I've owned exactly 2 e8500's and they both do 4200 without extreme cooling. I've also had 3 e8400's and they topped out for me and air at 4000. It seems about 200mhz is the average difference between the e8400's and e8500's. For me the extra 200mhz is worth the extra money.
e8400 q813 4.2ghz @ 1.36v air 8hrs prime stable here.

Well, its official. 445 mhz on the FSB is as high as my E8400 seems to want to go. Even at 446 it loses stability and crashes/randomly shuts down. Guess I'll have to be satisfied with a 4 Ghz overclock until I decide to buy a better chip.

AMD must be giving them some real competition heh?:rolleyes:
It would be nice to get an unlocked quad for under $1000.
They are just selling old stock, to get the new CPU's in... Clock for clock your comment might be true in some cases as AMD needs to play it this way with low prices... But once you start to OC, no need to tell the story there I think... Sadly for you Extreme CPU's hardly drop in price,...Quote:

Have you tried any higher?
How much are these babies going to go for?
woot new dual cores!! :D is 50% OC on an E8600 easy to do with air or water?
Let's see what the new ones can do. That looks like a good start by cstkl1, but I'd like to see if it holds up for 5 hours, not 5 minutes.
Still, the 10x multi with the E0 stepping looks like it could be fun.
Hoping they are less sensitive to high Vcore :DQuote:

havent benched anything yet..
one note.. the EO temps are kindda stuck on core 1 with min 32.. but core 2 moves freely...
second.. the vtt/gtl setting of previous e8500/e8400.. now is redundant..
My wife hates computers and overclocking :)

Looks like Intel still hasn't figured out how to make a sensor that is accurate at reporting low idle temps but at 5000 MHz, who the hell cares! :DQuote:

I know people will start with, Orthos for 5 hours but this is enough for me with those temps. Will never keep it loaded like that in real life anyway.

That's a nice OC :up: especially for air! But surely 87c is faaaar too hot! I thought 65c was the max temp for tese chips!Quote:

Yeah, i'm not worried about the temps at all. It will never get that hot in real l ife + it's a lot less then the max ~100C limit shown my Real temp. I put Coretemp in there just to show the VID :)
I just got an E7200 in today and it's VID is 1.1500v and it's batch # is:Q815A358it will run stock steeings on 1v so 2.53ghz in 1.00v heres the SS of the VID

I'm quite happy with the results.:up:
Could be worse.
just got my intel replacement in and its batch q817a623... anyone played with those yet?? i will not have time till this weekend most likely
The worst one reported is a Q817. I had a q817a6XX and it sucked, 'nuff said. I had troubles reaching 3600MHz even with 1.3Vcore. Compared to the one I have now, wich is a Q815 that easily does 3.8GHz on 1.14Vcore.Quote:

Here's a post on another Q817: http://www.xtremesystems.org/forums/...postcount=3243
I have only seen one report of a Q817, so I bought one hoping for it to be better. No luck though, had to buy a Q815 to replace it.
arghhhhhhh i have no luck, well the box is still sealed so it may be going to ebay since its brand spanking new.. then to try to find a good chip,..i dont know yet ive been without this system for way to long now though for different issues.. getting ridiculous
doubt you have the worst luck. i have had 3 1.225vid E8500's in a row now.
this latest one can do 4.25ghz @ 1.35v though so im not too disappointed.
dont know man it sounds like we may be in the running together.. this is my third e8500 the last was actually no good i had to send it back.. i hope to hear more feedback on the 817 and hope its better than that one was
My E8400 Q816A does about the same with 1.35.Quote:

ive noticed. everyone with a nice high OC on the E8400/8500. none of you have them on a gigabyte board. or at least i havent seen one..
i have the GA-P35-DS3R. im stable at 4.0ghz with just little voltage increase heck i havent even increased my mem volts any. but i cant get any higher stable...might it be my mem holding me back.crucial ballistix ddr2 800(pc6400)
another question. i see some 5.0ghz OC's very nice. are these OC's running at that everyday? is 4.0ghz good for a everyday 24/7 useage? i have posted some here and am alittle still in the noob section for OC'ing so if i sound dumb asking these questions bare in mind im still learning as i go.....thanks for any info
ooo yaaaaaaaaaaa the E8600 & BlackOps is my next goal
whaaa im on a 815 and it took me 1.28V to get to 3.8Quote:

i dont remember if the 1.3625v would let me be stable at 3.8ghz or not.
so then 1.3625v isnt bad at all for running 4.0ghz.
I said that the retail E8600's comes in August ;)Quote:
