is ti a e8400 or 8500??

E8400, I didn't find much on my batch, in fact I didn't find any post or test on 805A246...Hope to have thursday 2 more to mess with, maybe better maybe suckier then the ones I owned before....

[zfactor]

mine is a e8500 and i cant find anything anywhere from real tests on it.. im afraid it will suck if i open it and use it.. ruined my day after awaiting a nice new 807a..sucks

what were your last 2 batches that sucked??

[shiznit93]

I just got my E8400 running, 445x9 prime95 small stable at 1.312v. I have a big problem though, idle temps in RealTemp are 51C! while load is 60C. How come my idle is so high and it only goes up by 10C at load? My Q6660 had much lower idle temps than this dual core. Last week I lapped my TRUE 120 because the surface had scratched my Q6660 a little bit and I wanted it to be smooth, did I mess it up or is it just a bad mount?

idle:


load:


What could lead to such a high idle but small delta to load?

Tomorrow i will recieve my new E8400 Q807A097 . Hope it does a great job

Q808A442

[JTeg86]

Here was my max on air with my E8400 Q745A357. I didnt want to go any higher than 1.39V with air, even though it had more left in it

My 24/7 speed is 4.1Ghz @ 1.34V

Q808A442

yeah i hear those suck pretty bad i guess im lucky i didnt get a 808. were they really that bad??.. just wish i had more info on this thing.. exact number is q805a500...im torn on if i should rip it open and check it out.. guess i could always ebay it..


so what would you guys do?? keep it or return it and hope to get a 807 or better?? seems these are getting a bit worse with the newer batches like 808 up??

also where is everyone getting these older chips the q7xx stuff?? i cant find them anywhere.. ??

[nugzo]

I have an e8500 q807a. Max stable on air is 4200 MHz 1.375v in bios 1.41v in everest and asus pc probe.

[zfactor]

on another forum a guy has a q805a e8500 at 4.1 with 1.31volts.. so it appears maybe they are about the same or close to it.. not sure..

[aoch88]

I have a question and in fact I still don't have an idea what is the solution.

My E8200 does 505x8 Prime Stable (Small FFT) but failed Blend after 30 minutes.
When I do a Blend for 505x7.5, it works perfectly fine.

Now, what's wrong? it looks like the RAM, etc can run 505FSB stable because on multiplier 7.5, every tests (Small FFT, Blend) passes but the moment I use default multiplier, it is screwed.

I've seen questions concerning same issues and have experienced it myself. I haven't heard a good answer and never figured it out. My system was completely stable other than blend. If i were you I'd run a few hours of OCCT, if it passes, then I wouldn't let that blend bother you.

[aoch88]

Thanks nugzo but I tried OCCT and it failed too. Well, these chips are weird and despite failing Blend, I could still play COD4 and other games without problems for hours. In fact, Windows never crashes. I tried upping VTT and Vmch without any luck. Perhaps these stress test softwares is not the best to use for our 45nm's?

[The[R]eaper]

so where can i find one of these glorious 807's? i was about to order from the egg but i figured i would check here first on what batches to get.
where is everyone getting theres from?

thx

Here's my chip, got it couple months ago.

BX80570E8400
Q743A689

I've gotten 4.6 at just under 1.4v on watercooling

4.6Ghz Orthos stable at 1.4V? Are you kidding me?

[little_scrapper]

Can someone make a spreadsheet with a breakdown of the max OC's,

[Kean]

4.6Ghz Orthos stable at 1.4V? Are you kidding me?

Who are saying that its orthos?

[aoch88]

Who are saying that its orthos?

I was just making sure Well, if it's a plain SuperPI screenie at 4.6Ghz then I'm sure many folks could do it - nothing special really.

[ante_ante]

Can say that E8400 @ Q807a097 isn´t so good. Need like 1.35v for 4ghz stability. Was hoping for lower vcore but that seems to be a BIG dream

EDIT: About PLL Voltage, is there any risk of frying the cpu over 1.6v or is it safe ??

I don't think it affects the overclock a lot. Well at least in my case, I had it at the lowest voltage and still manage to get things stable.

I'm still here with my Q747A373 @ 3.85 GHz with 1.4 V.

Can't decide if I should get another one or wait for other CPUs to come out. This one makes me angry

[Pt1t]

I can say that E8500 Q809A655 is very good under aircooling.

i have 4ghz 1h occt for only 1.2v vcore

i m still testing it.

[Leeghoofd]

Q816A on the way to me... will post hopefully next week some results

[DoObs]

Guys not orthos stable basically superpi run and thats about it.

Dont think it was stable.... will be benching it again to see if i can get higher, just awaiting to order DICE and get a pot from Flytek.
