Am i missing something about the rated FSB? How come you have it running on 2750Mhz?? (CpuZ) Isn't the FSB for the e8**00 1333Mhz?
I was scared of the high rating, mine is at +-1750Mhz and cant oc more because of mem not going higher then 860Mhz...
Hey guys. First post here :D
Just wanted to ask where do you get your E8500 E0s from?? I want want and all my local stores don't have it. I saw some forum sites that sell E8500 E0, where I can order online.
Anybody else knows a store where I can order E8500 E0 guaranteed, to Canada?
Thanks
Edit: I've been siting here with all my other parts (Biostar Tpower I45, 2GB OCZ Reaper HXC, Corsair HX520 watts, and antec 900 and Ati Radeon 4870)
tankguys :D
They had the E8500 E0 before? Only E8400 and Q9550 are there.Quote:

for a vista rating of 5.9 for cpu if you have a dual core the frequency must be over 4.1 ghz I didnt get a 5.9 rating until 4.159 or something like that
no way man on C2D E8xxx @ 3600 hits 5.9 on Vista
gosh I want the 8500 E0 soo bad, been waiting a month now will ALL my other parts collecting dust here. Its so tempting not to open boxes :(:(
fry's this weekend has E8400 & ecs G31-tm mobo for 149.00 usd :D
gonna pick up 3 more this weekend :up: this batch outta be eo's
Guys, amazing results so far, really interesting watching this thread! I've got a EP45-UD3P coming in the mail as well as 4GB of G.Skill DDR2 800 CAS4 which I'm planning to run at around 500Mhz...
Anyway, not sure if I should go for a E8400 or E8500 E0 cpu. Everything that I've seen shows the E8500 clocking higher than the E8400 even using the 9x multi instead of 9.5. I'm pretty confident that my mobo will easily run 500MHz FSB so is it going to come down to the chip? My goal is around 4.4GHz...which CPU would you go with?:shrug:
I got this one,

@true what kind of volts did you use for that awesome OC.
1.38v under load, though the BIOS was set to 1.4 I believe. I was able to attain 4.5 as well last night messing with it. I need water for the heat though.
sorry guys for little off topic.my E8400 cannot work with 6.5 multi is it ok or is a problem with cpu?
Got my Q827A E8400 cooled on Xigmatek S1384/ Maximus Formula stable on 4Ghz @ 1.240V around 42 Degrees stressed :D (auto voltage)
Cant go higher because mem wont go over 920, will get new ram soon to hit 4.5+Ghz:rolleyes:
(i dont like overvolting ram at all)
I want to thank everyone on this threat, its realy high quality information and helped me alot :up:
p.s Just cant compare my E8400 to my AMD X2 5000+@3.2, AMD is really far behind on performance and temps as it could not handle most games maxed with my 3870X2, but the E8400 can for example :yepp:
@OCX600RR;
I think that can be a problem with ddr2 800 because the speeds u c here (+-500mhz) are half the effective speed, with wich the speed is usually indicated.
PC6400 will run on 800Mhz effective and oc to +-900Mhz, but CPU-Z will say it is running at 400Mhz (800) or in my case 440Mhz wich is 880Mhz effective.
And because the RAM cannot run slower than the FSB is running you will have this:
CPU: 488*9=4.4Ghz
RAM: 488*2=977Mhz effective and i think that will be a very high oc for PC6400 800Mhz RAM but maybe possible.
For 45 euro you have 2GB 1066Mhz RAM wich will get you there i guess:)
I learned this trying the exact same thing with DDR2 800...:p:

Where are you located?Quote:

I am aiming to get 4.4-4.5 Ghz. I will be running it with Thermalright Ultra 120 Extreme + 2 12cm fans. So should I get the E8400 or wait for 1/2 more multiplier and get E8500?
what I would do is leave cpu at stock and overclock your ram with 20 mhz increments until you find the stability wall, basically I had thought at one time my 800mhz ram was holding me back however I put cpu to stock and got my 800mhz to 1200 with slight voltage increase backed it down to 1120 or 1150 for overclocking manage to get my E8500 to 4.7 4.8 once I get my new stuff ill be able to puch it a little furtherQuote:

@true. thats awesome!! good to see you having such great success after all the trouble you had with your q9450.
Thank you, :cool:
Ok so guys. Should I order E8400 E0 from tank guys, or wait for a E8500 E0:(:(?
Just buy the e8400... I bought one with 1 idea: 4ghz gaming, it does 4ghz @ 1.20v hours prime/orthos stable, good stuff for a cheap cpu :)
@ 19*12 gamer
I looked at the Extreme Bandwidth section and G.Skill's got a review of the 4GB G.Skill DDR2 800 Black PI series RAM which I'm going to be using and they've got it at 1000Mhz 5-5-4-12 at 2.1v, so I'm hoping my sticks can do the same.
my 24/7 rig. I like it!! comming soon Thermalright IFX-14, I think, temps comming better.

what about 4.3-4.4 Ghz on <1.4 volts? will that work with the E8400 E0?

That what I have actually less voltage then that. I think 1.38 is good for mine to have that stable. I pushed it to 4.7GHZ~ that required 1.55v
@OCX600RR;
You're right! :doh:
I just didn't want to overvolt my ram but with 2.1v its 1Ghz stable.
Stressing the ram right now typing this and so far (15min) no errors :)
Im gonna try to get e8400 to 4.5Ghz right away.
Awesome man, good luck with it. I seriously cannot wait to get mine and start clocking that puppy haha.
Along with cool temps in the house comes cool temps on the CPU... running 29C right now at idle. Lowest I've ever seen!!! :up:
Alright, looks like i'm going to be buying the E8400 E0 from tankguys.
Does anyone know how long it takes to get shipment?
Would it be cool to run my e8400 at a corev of 1.47 and a vtt of alittle over 1.4 24/7 if I keep my core temps under 60c? Would I really have to worry? I have a Biostar tpower i45 and the voltage increments in bios are huge and its really limiting my overclocks.
Got another couple questions for you guys:
1) What's the best thermal paste? I've been using Arctic Silver 5 and so far it's worked best for me but I see alot of you guys are recommending MX-2. Which is better?
2) I've taken a look at the overclocking list in Excel and some of the E8400 E0's are at 4GHz with like 1.3v or something close to that. Are the numbers recorded in the list the MAX overclock for each batch chip or just what the user is running the chip at?

When i leave the RAM Voltage on auto i can oc my CPU to 4Ghz resulting in my RAM running 890Mhz and that is stable and cool 14hrs stressed.
My E8400 needs 1.24/1.28V for this oc but i dont know how to manage the voltages for the cpu,ram,nb etcet.
At 4.2Ghz/910Mhz is a wall i cant pass, the system becomes unstable.
Can anybody point me in the right direction?
I would love to c reference settings for 500*9 for a e8400.
And why do i have "A" stepping in cpuZ? (Vista32bit)
(Q827A345 pack date 14 aug 08 SLB9J)
@xpower;
I can run my E8400 with multi on 6.5 just fine, too bad does not change anything about my fsb wall.
I can run my RAM even on 1066Mhz 2.1V stable but i just cant oc my E8400 fsb above +-445 cpu-voltage on auto. (i cant boot setting cpu-voltage manual)

However I can back down to 4.4 and run 1100 on the ram. Seems that as the CPU gets clocked higher the memory affects stability of the overclock. Havent found a solution but for me it's either 4400/1105 or 4520/9x0.
thats a relief! thanks for letting me know. :up:
That is exactly my problem.
I was hoping my 4ghz@1.240V would go 4.5+, now i know why i cant reach that no matter what voltages.
Ill get new RAM soon, any suggestions for pc8500 2x2GB sticks?
Right now i am thinking of Dominator or Black Dragon.
^^ G Skills for the WIN!
19*12 gamer:
CPUID: E8400 (C0) = 10676
CPUID: E8400 (E0) = 1067A
When CPU-z shows a stepping of A, that's a good thing!
For some unknown reason, the Intel Spec Finder for the new E0 processors has the wrong CPUID information listed:

dang i wish some of you guys had a gigabyte board..lol all you lucjy dogs with the ASUS boards.. i along with you all i cant get any higher than 4.0ghz on my E8400 co cause of my mem also. plus with my gigabyte board i have to really crank up the vcore to get it stable at 4.0ghz.
1.475v in bios and once said and done only 1.34v??? to get me up to 1.365v i have to hit like 1.600?? or something to run at 1.365v
i know the ASUS board mainly the P5Q models tend to like most mem. does anyone recomend any mem that will work fine with the gigabyte GA-EP45-DS3R? you all kill me with these low vcores and high OC's im jelious of you all...lol its all about the board...
.. been messing with it for two weeks, just found its "good spot", not really sweet tho, many of you need less than 1.3v for 4g:p:,.. happy with it now
vcore bios 1.31875v, 1.36v cpuz idle, 1.36v load

wow eye feel lucky now .. 4.5 & 4.7 is eazy with my Firestix's pc6400

Anyone got a E8400 E0 working on a Abit IP35 Pro?
I sold benklottie an E0 E8500 on ocuk and he got it to 4.5 with 1.4v bios i think...the IP35 is a pretty good board for wolfies.
so, does it make any sense that i buy the DFI DK P45 T2RS + with my E0 E8500 ? I have felling that it might bend more than my asus P5K with crappy 500 FSB max.
someone have this e8400 fpo\batch? Q818A233? is a E0?
thanks
Yes it does make a lot of sense :)Quote:

Hi!
My ex E8400's fpo was Q807A464
it was p95 stable at 1.328v 9x445 in p5e(default bios)
and 4.2ghz @ 1.408v proof
it wasn't a unique cpu :(
Hello,
I just picked up an E8500 E0 Stepping and I am priming right now at 4.3 with Vcore set in bios at 1.275 prime95 for about an hour:up::up:

I need high volts for nice clocks, E0 owners needs lower volts, but they top out usually becouse of too high temps :up:
so you are saying that E0s heat up more than C0 with less volts?
Well to be honest, i dont know does the E0 - C0 Any difference, VID is the thing that makes difference!Quote:

True, the difference is sometimes about 5C or even more (@ same volts), but as it was already mentioned it's quite logical. The newer stepping probably wastes less energy by consuming and outputting as heat same energy (thus same clocks & same temperatures) at lower volts. But that's just my humble theory.Quote:

Howcome it's showing 1.472v on the core in CPU-Z as well?
Yeah its true! :shrug:Quote:

Any more input is appreciated. =)
Got an E8500 E0 some time ago. Batch Q820A925, one of the earliest. VID 1.25V. :rolleyes: Both sensors get stuck @ 36C (still way better than previous E8400 C0 with temps like 32/19 and 10C difference under load :p: ).
Currently running 506 x 8,5 = 4302, vcore under load 1.344V. Very hot compared to C0 8400.
Finally some time for LinX to do its job. :) Temps are insane though (~75C), and no Thermalright to be found anywhere around. :(

Just a quick testing so far.
It's a DFI board with 965 chipset. And CPU-Z isn't perfect. Looking at what Speedfan shows on most of voltages one can assume CPU-Z is wrong too.Quote:

Too many variables b/n you and him, and he wasn't comparing his cpu to other E0s but to C0 e8400 he had previously, so you data is really doesn't tell him or anyone else much. If you were to test a C0 cpu, then we'd be talking about something ;)Quote:
