**Official e8400/e8500 Retail OC Thread

[Ozzfest05]

So I just did some runs with the 8500 chip using my good ole' Infinity cooler Best PI times ive ever gotten with it so far however I think the voltage can come down abit I know I can do atleast 5-5.3 ghz however the 680i doesnt like 500+ fsb so Ill wait for the new boards I got coming in (shown below in sig) and my ln2/DICE pot.

Can anyone comment on a E8400 FPO Q817A378
I can get it brand new for a cool 145 bucks
To spend or not to spend

[cincyrob]

the Q819 batch is what i just got in my RMA. it runs cooler than my previous E8400... i can only get mine upto 4.0 stable but i think my lack of knowledge and know how with my board is holding me bac
k. plus my mem ddr2 800.. its rock stable at 4.0im sure you can get higher with it.. so with itbeing Q817 batch its not the E0 stepping so thats going against it there.... but for $145 that is sweet.

Thanks for your comments.
I'm looking for a 4.0GHz chip with resonable volts. It will be air cooled so stellar clocks are not to important. My son needs a new rig and this chip comes at the right time. As long as it will hit 4.0 I'll be happy.
Think I'll pull the trigger on this chip

[cincyrob]

yes it shouldnt have a problem hitting 4.0ghz. just be carefull and not over juice it. take it up little at a time to get the lowest volts to run at 4.0
i was running every day at 3.6ghz. but with my new board and my new RMA'd CPU i got it running real nice at 3.83ghz no problem i would have left it
@ 4.0 but like i said my volts were to high for me....


iknow guys not to xtreme....lol
got a Q9550 E0 stepping in the works that i am gonna go crazy with...

Yeah, I think 4.0GHz is reasonable to achive around 1.3-1.35V with that FPO

[OC4/3]

1.7v?? You guys do realize you are destroying a 45nm chip with that much voltage right?

radaja - 1.9 @ 1150. Even 1100 is memtest stable @ 1.8v though.

Nothing happened to my chip,same as before
Done under liquid loop(Fuzion V2,MCR220,Radbox,Generic 1/2" ID Tubing,Micro Res,Nirox P2800 modded pump,more or less 2.5m h/max)
I want to try big 5 someday
My usual performance product is 45.3k or so

[whe3ls]

well im priming @ 4095 with 1,296 vcore with my older C0 e3110. it seems my chip doesn't seem like to go above about 61-63c.

[Ezekiell]

Just to be sure I have the correct setting for my E8400. In Coretemp 0.99.3 -> settings -> Tjunction Max offset I need to put -5C right?

and in Realtemp you don't need to adjust anything right?

[whe3ls]

i believe that correct

[Peter949]

anyone get a q827a e8500 results?

99.3 Sets 100oC which is correct for the 8400 so no offset needed.

@Peter949;
Just got my e8400, will recieve mobo (maximus formula) within 2 days.

I have a Q827A345, but haven't found any oc-results, I will post them here.
It says S-SPEC:SLB9J
Pack date: 08/14/08

It says:
Version: E43455-001 1.26V max, is this normal? I can run it on 1.4 max right?

Yes, no worries!
It has been discussed over a thousand times, but then again!
You can safely give 1.400V to the CPU from the BIOS! Which actually will be lower than 1.400V because of vdrop, as you know.
Well, of course, you need a proper (air) cooling solution, which is almost everything but the stock cooler, and you'll be fine.

[cka3o4nuk]

ppl any sugestions
i have a e8500 e0 1.25 vid
stable 533*8 1.375 bios 1.31 under load. cpu fsb set to 1.28 mb- asus p5q-e
can you sugest vcore and fsb setings for 533*8.5

Nicely done... good find... List is fully updated again... bring on them results

Nice chip mate!

[anzial]

Did anyone notice that E0 cpus run a bit hotter than their C0 counterparts, especially when oc'ed?

[PytonOrm]

well can i play with you guys =)

E8400 E0 /Q827A345/ S-SPEC:SLB9J/ Pack date: 08/14/08

I put it in a Maximus Formula on AIR Xigmatek s1283 (i hate pushpins)
1.26V @ stock in bios and CPUz

I tried to set the FSB to 450 but failed to get the resulting Rated-FSB below 1700Mhz.

Dont know why, nbstrap can be set on 200,266,333,400 and the higher this is set the smaller the mem jumps will be when oc-ing, but it does not manipulate the rated FSB strangely enough, maybe i've bin on AMD to long .

Results so far: (finished last night 04:50)
after 4 Hours of Orthos "small fft" cpu stresstest cpu is 38 degrees celsius. (still running)

It is working at +-3.870Mhz, +-1780Mhz Rated FSB, stock voltage (auto)
(430*9, nbstrap 400, stable for 4+ hours)

voltage reads 1.268 in CPUZ I think this is good

Can anybody help me go higher without this ridiculus high Rated FSB?

p.s It is flying in Vista, everything is instant, only user exp.index gives 5.9 for everything but calculations, wich is 5.8 WTF. (no difference 3Ghz or 3.9Ghz)

I've read that you almost have to have a Quad to get the 5.9.

Finally got my p5k-e for my e8400, will post some results tomorrow.
