**Official e8400/e8500 Retail OC Thread

[RedBull78]

hah. Naw, I'm more than satisfied with it, I love these e8000 series, just want to hunt for a different one. This one will find a good home.

4.5ghz for 200 bucks isnt good enough? lol

Anyway, goodluck with the 8500

[trans am]

who will ship e8500 to NY, USA? I need one for Ln2. please pm a link.

[Viss]

anybody using setfsb/clockgen if so which version and what pll thanks

Just recieved my E8400 from the Egg.

FPO/Batch = Q746A489
Pack Date = 1/09/08

Will post results as soon as i get my loop back up and running

[RedBull78]

Were you there?

No. But i'm entitled to give my personal assumption on the subject.

I still believe the cpu is not the culprit to this clock degration but some other factors.

I had this problem with DC opteron where it ran stable for days at 2.9ghz until i decided to push it further but came to dead end so when I set everything back the way it was it became unstable even at stock speeds. I did everything by the book-clearing the cmos, taking out the battery but nothing. At first I thought it was the cpu so I ran it on my older epox939 board and the cpu ran just fine. I poped it back in my dfi and decided to reflash the same bios and boom the opty ran at 2.9ghz stable again.

Sorry but I just don't buy the fact 1.4v would degrade this cpu in just a few days (unless you try it without the hsf). 1-2 years maybe but not 3-4 days..It's impossible. Did someone mention their cpu's blew up or something? Well there you go. Faulty PSU is the biggest killer to all components.

I got the exact same batch as you loc.o

BUT in running it in Maximus Extreme, and i must admit, this board really sucks.. I got a feeling the cpu can do alot more, it craps out on about 500 in this board, but it boots without a glitch at 550, god damnit..

what do you think, i got same batch as you, and my VID are as low as 1.0500
and 510 is a no go into windows, nomather what voltage on the important things... how was your experience with maximus?

regards.

[Zucker2k]

it will be a new one... Is that bad? (i cannot follow )??

This board was released more than 6 months ago, it will need a bios update to work with 45nm. You'll need a 65nm or older cpu to flash to latest bios before you can use it.

You may be lucky however, and the board might just come with support for 45nm. You should probably ask in the IP35 thread and see what folks say. Goodluck.

Havent really tried much but sounds familiair. With maximus bios 0401 and E6600 550FSB air and 590FSB with dice was fine. Now using bios 0907 and an E8400 (can do 590 air on Commando). Simular settings for Maximus as with E6600 tests but not much over 500fsb now either. Rather sure were both missing a setting here and there because board shouldnt have a problem with it i guess..

nice FSB

[JoeBar]

I'm retiring my Q748A too. It's a lazy dog compared to the rest.

Yay for 8500 though!

I may have the worst Q748 there is...

It needs 1.35v for 3.8ghz (which is the max stable oc). 4.00ghz is just out of the question regardless vcore...


Return it tomorrow ASAP!


Tested on P5E. That's for ppl thinking that P35 is the problem. No Q748 is the problem...

Is it Q748A102 by chance?

loc.o, nice cpu mate, i ordered an E8500 myself, could no longer stand this E8400.

Im really sick of it , what can that setting be? its not an unknown fact that x38 cant do very well, the only board ive seen getting good FSB are the P5E3 WS Pro..

maybe i should try a P35 board? and noo, no commando, im using ddr3 now..

think im gonna sell this one, cant take this anymore making me nuts..

regards.

No it's a Q748A242. I'll try another 8400 (a Q746, if i can find one) cause it's for my 2nd rig.

I'm reserving 8500 for my main rig. Still debating if i should ditch quad for a 8500 though...

I got 545fsb on my max formula; I'm pretty happy with that. I believe I can go higher with relaxed performance levels but max fsb is not what I'm after.

The best way to judge the strength of what I consider to be "shoddy" overclocks is to ran some 3D benches with them for the following reasons:

1. the guy who did 600fsb with the p5b-deluxe had pci-e at 1x (a common problem with that board)
2. the performance levels get very relaxed past 400 progressively towards 500 and beyond. My P5B-D (C2) had performance levels around 11 with only 450 fsb.

I am running 9x500 with performance level at 7; something's gotta give - loosen permance levels = gain max fsb. Also, bioses still need to mature for x38, and remember, the strength of x38 is not necessarily just high fsb, but a combination of high fsb + performance (relatively lower performance levels).

Even though x38 is more or less a tweaked-for-performance derivative of P35 chipset, wasn't it meant to be the replacement for 975x? Or is it P45?

What I'd like to see, because I've done it on my x38 board, is a P35 chipset doing 9x545fsb with performance level 7; and pci-e @ x16

ok Tbh, i have forgotten the Booster ehhh... ive allways had it on strong, and booster lvl 3 ... couse when i did have my conroe in , it didnt mather what i did it sucked nomather what, but ok, ill try to lower it a bit and check. ..bbl
thanks..

EDIT: didnt change anything at all. still as crappy

This 1s all the way 4m Bombay, India

Got my E8400 with the Batch #Q746A447 Dated 7th Jan '08, last nite.

I'm on AIR (TRU120E) & ve a ASUS Blitz Formula board with 4x1GB PC2 6400 Crucials & a 8800GT. Trying 2 get is 24/7 stable at 4.32 (1.4Vcore).

Managed 2 boot @ 530x9 but I'm sure I can do better.

Here's a simple SS on XP with Spi1M, under 10s score (my 1st under 10s score) @ 4698MHz which I feel is not bad at all on AIR !!!

[The Viper]

E8400 Q744A (ON AIR)

4.7Ghz 1.64V



Can Boot at 5.0Ghz but cant get into windowa, mobo is the limiting factor, I think. I need 1.44V for 4.3. Seems like a good chip, but def not as good as weeks 45 and 46.

Sigh only good for 16hrs 15min on prime 95 and it crashed again core 0 runs at 1.304v just fine but core 1 always crashes even at my current 1.32V I guess its time to bump the voltage another notch or 2 for my 24/7 clocks, I can see its in reach now though. Can load windows and run 3dmark 06windows at 1.42V @ 4.6 but gets too hot w/ my Tuniq at only 1350rpm. will need to replace the rear fan in my P180 if I want to push it more /sigh

why does coretemp and orthos show 3780MHz and cpu-z shows 4247MHz?

[X.T.R.E.M.E_ICE]

why does coretemp and orthos show 3780MHz and cpu-z shows 4247MHz?

because some people up their CPU speed in windows instead of bios. CPU-Z shows speed in real time

[majestik]

Yeah boot at 420 then go up.

[humeyboy]

Not true m8.

Windows and most apps inc Orthos will always read your DEFAULT MULTI.

Thats why when you lower Multi and Raise FSB you get a mad high reading.

CPU-Z however will read Multi/FSB and CPU Speed correctly.
