Does anyone use the Orthos_Stress_Cpu w/ Gromacs Core feature to determine overclock stability? I can use considerably less voltage to be 3d stable and Gromacs core stable.
I only Game,Surf and do large rar file unpacking. I would like to see how many of you use different methods to determine stability.. i think prime and orthos small fft stressing is excessive.
Your opinions?

Setting CPU Margin Enhancement to Performance on Ket's 1406 BIOS for the P5Q-Deluxe seems to have fixed some instability issues for me. May try for higher later, or a lower vCore. Yeah, higher sounds good.

I got an E8400 EO, but I think it was a lemon. It would continually crash my system when benching and was not stable at 4.25 GHz with 1.37v load (1.4v set in bios). I have had 5 different E8400/E3110 and used the similar setup procedures and that one was a dud.
But subsequently I bought a used computer (AOpen) that had a Xeon E3110 in it (with a P5K-VM, 2G Ballistix 8500 & OCZ 500w for $250). Turns out this Xeon is a Golden Chip compared to the other Wolfdale's I had. It has a 1.225v max. VID.
I put the Xeon in my main P5K-Deluxe rig, and have it running at 4.25 GHz at 1.34v, which is way better than my other chips at similar voltages. I got up to 545FSB @ 8.5 multi (while running 4 x 1G sticks of Ballistix 8500). None of the other processors including the EO, could not go higher than 513 FSB, even with higher voltages.
The downside of this Xeon C0 is it runs very hot, reaching 72C while benching. On the other hand my dud E0 got only to 58C full load...until it crashed.
My bios settings are: cpu 1.375v; ram 2.0v; VTT 1.2v; PLL 1.5v; NB 1.25v; SB 1.05v. Transaction Boost Level "2", everything else pretty much Auto.
I only had time for minimal testing so far, but will see what it can really do this weekend.
:up:nice job lucky you some have better voltage with E0 but 1.480 for 4.65ghz really good mine need in range of 1.58 to boot at 4770mhz far from be a good chip lol but its la vie les amies
anyone have an E8400 batch Q830A179? how well they clock? I can buy one and at a good price too ... waiting 4 u'r opinions
just got one E8400 Q832A913, orthos stable 4,2Ghz 1,36v :hammer:

Hi there guys, i'm running a Asus P5Q Deluxe with an E8500 E0 and struggling to get it past 4ghz, can anyone help me out with what to set in the bios( maybe someone has the same mobo and chip)
Thanks
Try posting that in the Intel section, not in this thread to keep it on topic :)
People need more info like what you are using, RAM and speed, volts, vtt etc. also what cooling. but id suggest making a thread in the intel section if u want the answers :)

I've been confused so far - I've had the pleasure of owning 2 E8500 (one C0 and 1 E0) and 1 C0 E8400 - plus my current e8600
And not one of those chips would even think about being stable at 4.5ghz - I tried up to 1.45v and to no avail - its not an issue of FSB by any means
All kinds of people are hitting 4.5ghz on much lower voltages and I'm not even stable at higher .... ??? :shrug:
am I just unlucky ?
Believe me it is'nt that bad bein on air as long as the Temp in the house stays cool..In the summer..i keep my house central air at 69c all summer long but my rig is sitting under a air vent so my two 120mm's blue Led's are sucking in the central air :yepp: the volts on your cpu is kinda high..I guess it will be on a gigabyth board but there boards have VDrops..I got mine at 1.350 in the bios but it dropped to 1.312 sometimes 1.280:yepp: oc'd 3.3ghz that's all...Is that a CO or a EO stepping you got? try not shot and hold to much volts to your cpu 24/7.i would'en like to see you run back to the store buy another:shakes:..I know the E8400 is rated at 1.362v max

@nefariouscaine
What cooling are you using though? Nb and cpu? water makes it a hell of a alot easier to get stable than air ;) volts also?
Ok went for my 24/7 power/performance/temp setup and am tweaked down for benching now with this chip
I only got it 4 days ago, and have a family and limited time to tinker lol :( though over 25+ yrs Ive had plenty.
Final settings in sig. I like that it does not get more than 10C hotter under full stress configd like this
Now onto the hardmod on the 4850 ! All cooling fans , heatsinks, and ect.. in place already , just have to find
a variable resistor to put in.
on the nb i have a small 40mm fan on the heatsink - running 100% - i have a temp sensor on that and even during 560fsb stress testing with the nb volts cranked up my sensor probe never hit over 50c which isn't bad as i had it cranked to 1.7v for those hours
on the cpu its in my sig - the Sun Beam Core Contact Freezer - but temps aren't my issue - its not like my cores are shooting up crazy high - i can boot at 4480mhz just fine - even run 1m pi some times - its just not stable and usually crashes - I could see how water might help if it was hitting 70c or so but its not even stable enough to hit those temps
now ln2/dice or chilled water - that might be another story with sub ambient temps
not sure if the board is the issue - I'm running 24/7 atm at 560fsb on 7.5x multi ofr 4200mhz - at 1.55v on the nb - about 1.392 vcore - 2.15v on the memory at 1:1 4-5-4-15 t2 - i think i have both gtl settings at .61x - transaction booster enabled at lvl2 - fsb ratio at 333
Need some help...
Currently attempting 562 x 8 = 4496Mhz @ 1.4v

hi guys,
i find a 8500 with batch Q819A103...
is that piece good for o/c?
looks like and old batch....
at the moment which are the best batch to o/c ( for 8500 and 8400)?
should i buy an 8400 or 8500? the mobo i have is "DFI LP DK P45-T2RS Plus"
thanks bro...
i will buy tomorrow an E0 stepping 8500
yes, my C0 3970 stabe. at 1.4 v
The E0 is much better
i buy an 8500 finally with batch Q746A580.
i will post some screen shoots later
Anyone seen Q836A368 yet? (e8400)
Got one here to test this week :)
C0's are not that bad they hit 4 ghz under 1.4
Wow I just played Day of Defeat: Source for about 2 hours straight, with 1.36v and 4.5ghz on my E8400 but OMG it's one hothead... 50 idle, never goes below it, and after a minute of Orthos I get both cores @ 67c... me thinks the temp sensors are broken ;)
Contact is perfect, my other E8400 never goes above 49 on both cores... so probably borked sensors
oh dont get me wrong i have a CO stepping E8400 i can run stable at 4.0ghz just fine.. it just takes a good effort to get it there and with 1.49v in bios giving me 1.37v actual. the EO stepping is just a better chip.
garrett. ive had 3 different CO E8400's the first 2 were like that very high temps. this one here at 4.0ghz will run around 38c at idle.. so there is something to the way they are makeing these chips/batches??????

E8400 E0 Batch#q829a103....24/7 SETTINGS
My E8500 Q827A366 VID1.25v pack date 8/07/08 needs 1.49v @ 4.48GHz; 1.506v @ 4.51GHz. It is an E0. Bought off Newegg. Complete piece of crap. Got an E8600 off eBay Q822A430, VID1.215v, needs 1.344v @ 4.52GHz, but runs EXTREMELY HOT! That E8500 @ 1.505v Orthos Small FFTs only gets up to 65'c highest, while the E8600 shot up to 79'c!!! Reseated over 10 times. It's the chip. Damn I never had any luck with good chips.
@Luckysevn
my last E8400 had taht problem with the high temps no matter what cooler i had on it... i got with intel and they RMA'd me a new chip. i have one of the latest/newest CO E8400 chips. and it is cool at all times now.it will barely hit 60c under intel burn test. at idle in the mid 30's.... it might be worth you time to talk with intel and tell them your have nproblems with the temps being so high,,,
Just got my new E0 E8400 in and it looks like i finally found the golden chip i think:

Comming from a old C0 which could not do more than 4 ghz i am amazed by which chip and how little voltage it needs. I know that so short prime shows nothing, but atm it is still priming: 15 min now.
Will post later if it is totally stable and also use intelburntest.
Batch: Q830A178
oh im sorry i didnt know what you were saying...i wish i could give air temps but the chip came out of the box and went straight to water...i guess its spoiled...:rofl: the thing never seen air cooling good thing because i only have the stock heat sink...but if you look above i posted some screen shots for proof
room temp at the moment is around 78F and is always degree or two with in that temp....ok well my water cooling set up consists of the following.....swiftech apogee GTZ water block...danger den blck ice extreme 2x120mm radiator...2 120mm 110 cfm fans...swiftech MCP655 water pump...XSpc clear in bay reservoir...hard core home depot 1/2 inch clear tubing...automotive grade hose clamps...distilled water and petra tech nuke water additive to kill any thing that might grow in my water
A lot of people get a 22c idle when they use real temp....but i didnt really check my thermometer when i told you 78c i guessed and right now my feet are a little chilly so it could be more 76F room temp my windows are open here in florida....but really who gives a crap about 3 degrees if your already running low temps...and the killer radiator comment was a joke any way...i dont know why your trying so hard to debunk my temps....if you dont like my screen shots i posted above...then take it up with the software writers who made Real Temp
If that a golden chip then I must have a golden chip also. My C0 does 4.0Ghz at 1.28V actual. I havent tried lower vcore yet. So I'm not sure of what it is capable of.
http://img212.imageshack.us/img212/6...zat128vip2.jpg
And Im using an old GA-965P-DS3 board with BIOS that only UNOFFICIALLY even support worldale. With a GOOD board with good bios tweeking options I bet I could go a good bit higher. ohh yea i have this thing running on a passive ninja!!! Only uses case flow for cooling. No fan on the cooler at all.
It primed alnight stable at 1.320 v-core at 4.360 mhz and also passed intelburntest (i run iwthout loadline calibration, so that is way idle voltage is higher)

So happy atm with this chip. Burn damn intelburn really push your chip. the temp gets maks 55 degress at priming. Intelburn test gets it to 67 degress.
sorry if this info is posted already, but how can I tell from the box what stepping a chip is. I'm picking one up from microcenter and I want to call in and have a sales rep tell me the serial off the box. What serials am I looking for?
I am not sure what you want me to beat.. I can use windows and run a easy benchmark like everest cache/mem test at 4500 mhz with that v-core, but for me that means nothing.
A overclock for me have to be intelburntest stable or else i won't use it 24/7
Try post a screen with that speed and a 5*intelburn test session, then we can compare. I did first get the chip yesterday, so just started testing.
Atm i will let run at around 4400 mhz with low voltage, because the only thing i use my computer to is gaming WOW and a litlle fallout 3, and both games run so smooth i can't feel any difference.
It's not logic, you have to admit that, you are able to cool a CPU below ambient temps with non chilled water...also your load temps are amasingly low... your sensors are for sure borked at idle, probably too under load... Tjcasemax selected is 95, I would set it at 100 or 105 for more realistic values...
These readouts got nothing to do with realtemp, pure CPU mate... but it's a nice CPU doing those speeds, cherish it :up:
every thing you said was debunked from the start...because True Temp reads 27c idle on the same board and cpu and dosnt go over 49c on 100% 30 min prime 95...so like i said its Real Temp that,s reading the wrong temps...i said true temp reads 22c idle and i got a reaction....people wanted screen shots so i gave them...i never said i believe them
just a little friendly competition..:D..you said you had a golden chip..:shrug:..are you gona cry or live up to your claim....so far my chip does 2 hour,s of prime blend while watching you tube and posting at xtreme systems while at 4.45ghz 1.322v if you want me to run intel burn test i will but i can tell you my board and proc are rock stable....its all in fun...im just trying to get you to push your chip further
nothing stresses my chip like youtube and xtremesystems. A true stress test. Intel should learn from the best
:shrug: your new values are more believable and even 32°C idle is still perfect... be realistic if you tell us you got 77° ambient, it's hard to idle at a lower value not ?
Just a tip :don't be agressive in your posts as you will not make many friends with this attitude...
Look for anything after Q821XXX and you will be fine... E8600 is for sure EO ; most E8500's too , but with 8400 you need to be carefull
thats while running prime blend at the same time for 2 hous...:up:...more than a few times its been 2 weeks at 4.45ghz and it still hasnt crashed...i deem it stable...:D...i would hate to think im the only one who uses prime 95 to check stability.........any way im going to dump this UD3R for the new lanparty ut p45 thats when were see some real gigahertz.......
below is something i got done working on 3.0ghz with less than a volt that last pick it jumped to 1.008 after i stopped the test the board keeps bouncing between v-core even when its not on load..
looks like I will be in this thread a lot now. I just picked up a CO stepping e8400 for $120 at microcenter. I got tired of the insane volts my current chip takes. I can't wait!!!
This chip just gets better and better. Intelburn test stable at 4.420 mhz with 1.328 volt (using loadline calibration now). It can prime at lower volt, but again i want it to be burntest stable before it is good for me
http://img221.imageshack.us/img221/9...0mhzng1.th.jpghttp://img221.imageshack.us/images/thpix.gif
could be because of how low i set my v-core in the test keeping the heat down its also water cooled thats the only thing i can think of....when its at 4.45.ghz 1.344v..it jumps up to 49c on prime 95....but for the screen shots above i wanted to see low i could set the v-core at its rated speed of 3ghz which was 0.992v and it passed an hour and a 1/2 of prime
Where are you guys finding the EO revision these days?
got a c0. running this OC now. Stable using OCCT, PRime95, but not the Intel Linpack Test.. anything I should do??
http://img237.imageshack.us/img237/5...prime95gj1.jpg
List your system, CPU/Mobo/RAM etc. in your sig. It'll help everyone to know what you're running on.
I'd start by setting your RAM to cas 5 and seeing how well your board responds to NB voltage increases. It does look like you'll be in the 4Ghz 1.3vcore (+/-) crowd, though. It's good company for C0's.
Finally, i find pretty good E8400 after several bad tries. It's Q830B153 Batch with VID 1.1875V. It's working Ortos stable with 450x9 (4050mHz) only on 1.15V, 4.2gHz with Auto 1.18V. Tried also 4.5gHz, but it's need some more voltage. Pushed to 1.34V and stop the Ortos after 2 hours successfully running. Needed also increase CPU VTT to 1.26V and PLL to 1.64V. All that with air cooling Zerotherm Zen120. With good liquid cooling the CPU can be pushed to 5gHz, i hope..
I've got a bad E8400 E0 Q832A378. One of the cores always craps out while the other stays stable. I need 1.34v just to keep both cores running @ 4.05GHz. One core will keep running in P95 @ 4.27GHz with 1.29v while the other errors out. I need 1.43v to keep them both stable. That's terrible compared to other E0 chips.
Ummm, didn't anyone else catch this? I really don't think that is the case.......can anyone say "new world record" LOLQuote:
Edit: also what is the limit for my memory anyway? Its OCZ Reaper HPC 2x1GB DDR2 8500 .. Right now its running at 2.1V, 1770Mhz, fully stable and passes memtest. How much can I go with this memory?
If your picking up E8400 you need to talk the saleman to look for
(S-SPEC:SLB9J) That's the EO Stepping number..If I was you..I
would go in myself and stand at the processor case and look for
the number.I gave above..The pack date on my is 08/07/08
and the Batch#Q820A832 atlease look for batch in the 820's
Best of Luck:up:
Finished the system in sig a week ago, still tweaking it. So far, I'm noticing this CPU seems to want higher voltages than most EO's. Batch is Q832A161. Got it from neweggs NJ warehouse btw. Can get a 4.5G overclock, but it takes 1.4 vcore and running the FSB up around 500 makes my RAM wonky. Cranked the FSB down a bit to try some tighter timings on the RAM, but noticing the vcore needs to stay a bit high. Right now I'm running 450MHz Bus, x9 multy @ 4.05GHz...which wants a vcore of 1.36. I can pass an hour of OCCT at these settings.
has anyone experienced a need to boost Vcore after a while?
strange, but a couple of days ago my computer became completely unstable after 2 months of running super stable....random restarts often, and a couple of restarts that would end up in non-reboots; had to turn PSU off, and start over.
I bumped Vcore from 1.28750 to 1.29325 and a little better but still rebooted. Then up to 1.3000v, and almost good but had two more reboots. Up to 1.3250 and now it is stable again! I didn't want to run that high of a Vcore, so I went back to FSB = 430 (3.89ghz), and put the Vcore down to 1.2835 and now it is running perfectly fine.
my board is a Asus P5Q-E, see my sig for more details
Yeah same here, though I have a feeling I never had enough NB voltage to begin with (only 1.34v in Windows since February 2008). I also, however, never played a 3D game long enough to really stress test. I played TF2 max maybe 1-2 hours at a time. L4D has me playing 4hrs+ per session, and pulled some Windows file BSODs (which I consider not as serious as the typical IRQ_LESS_THAN_EQUAL ones). A few bumps in my NB voltage, and no more BSODs. But I can't help but wonder if my 2hour OCCT checks are simply not enough (compared to 3D stable).
Hell I could probably drop my vcore back to 1.296vcore, but I'll probably play it safe like an old man and leave it be. Load temps are what, 1C higher b/c of a 2-step bump in BIOS. No biggie.
*actually you know what? Maybe we did experience degradation, and we :banana::banana::banana::banana:ing babied our procs with only 1.3vcore. :|
