4.0 with 1.26 volts ! exellent E8200cpu thier Tuvok-LuR-
I think I'm on to something, It may be the reason why we think our CPU's are
degrading. I created a new thread check it out here: http://www.xtremesystems.org/forums/...d.php?t=179965
Especially you Mrcape because I really think this is what you are experiencing.
just playing today to see...
Asus doent put lower than 1.1 volts...
http://i96.photobucket.com/albums/l1...untitled-9.jpg
you're lucky on my abit ip35-e lowest is 1.225v bios.
so here is my initial 4GHz OC on an E3110:

http://img339.imageshack.us/img339/5...4ghzti7.th.png
I am mentally preparing :rolleyes: for my FIRST OC as I am still waiting on my E8500 and mobo (either 790i or Asus P5E3 Premium).
Can the E8500 maintain a 1600 FSB with 1.3625v?
Will I need to increase the voltage of the anything else?
my e8400 needs 1.19-1.20v for 400mhz-1600fsb
i doubt you'll need 1.3625 :D
NB will need a bump tho
btw here's an OC screen of my e8400
it's weird no matter if i set 1.325 or 1.33 in the bios it gives 1.312 in windows. But it only did 2h on core 2 @ 1.325
http://img385.imageshack.us/img385/9...0355gj1.th.jpg
Thanks!
You should be able to set FSB to 1600mhz (set the memory to sync of course with stock timings) and not even touch the voltages on anything. I have mine set to 1800mhz and just barley bumped the NB/SB. You can even set the volts below auto or stock and run at 1600mhz. I cant remember what stock is but I set mine to like 1.26 @ 1600mhz FSB and it was very stable.
I could only OC my E8200 @ 8 x 502 Orthos Blend stable and nothing more. I'm not sure if it is due to the Foxconn Mars or my Ballistix doing the max. Anyone has an idea what is the max for Ballistix PC6400's? I believe it does 550Mhz 1:1 @ 15-5-5-5? What is the normal voltage required for that to run or it's not possible?
I've done 620 on those sticks 1:1 a the same timings, I am getting a pair of 1066's tomorrow, see how those scale with my E8400, ive already gotten my chip to 4ghz at 1.2v, and 4.4ghz at 1.4v. Trying to get ahold of DICE for some higher FSB, my board i have done 560FSB so yea ampt to see what my E8400 can scale up to.
I bumped my voltage every so slightly from 1.225 to 1.25 and I am running 1600FSB no problem.
Thanks guys but I'm referring to Orthos Blend and the concern is about Vdimm voltage and timings. I can pass Small FFT but just not Blend :(
can anyone tell me which batch or 8400/8500 are gd for oc and has low temp under load? thanks...am thinking abt buying one to upgrade my 6300
Oh yeah.... DDR3... Yes you would still link it for max stability. Maybe a 1:1 divider since it's 1600mhz memory. Anything beyond 1600mhz would need a different divider though. I might be confused and could use some input here from others on this thread but doesn't Sync give you 2:1?
i think your drawing these words too far away from their intended use in our situation.
linked mode refers to the memory speed varying according to the FSB clock speed. in my experiences, sync mode uses the default system clock (333Mhz for a 1333MHz FSB'ed processor) to calculate the memory speed, while link mode uses dividers.
every board manufacturer is going to be different, so its hard to use the terms interchangeably between manufacturers
Finally got stability at 4.050 9x450 today. :)
I had to bump vcore to 1.4v
My ram is at 1080 with 5-7-7-22 timings
I've only tested for about 20min in Orthos, but considering that I couldn't get more than 10secs with my old settings, I'm pretty happy. I will try to run a longer stress test to verify stability but it looks great so far.
On a side note, I can still boot and run superPI at 4.203 but fail Orthos almost right away and I don't wanna go over 1.425vcore.
So i bought an e8400 yesterday at a premium price, had i waited a few more hours i would have saved a $40. Okay fine, i was an idiot and i rushed, so i can deal with that. So i get it home and put it under water, and run a few test and i'm absolutely horrified to find i have a chip from the worst wolfdale batches yet... a q748
so now i tried to see what i could do with it and this is at follows:
stock voltage : 3.2ghz
1.31v : 3.7ghz
1.408v : 4ghz
not too mention the temps seem crazy: 70degrees under water (and not low end water either) (i even did three mounts to be sure), perhaps in addition to a crap batch, i might have gotten one with a concave base (will check when i get home)... Would that just be swell. All i can do is hope the chip fries and wait three weeks before exchanging it when new batches are coming in. Maybe i can try sell it and just get me a e8200.
So i got it stable now at 4ghz at an insane voltage
vcore 1.424 (vdroop 0.16), all other voltages at default!
One good thing is that during all my testing, i didnt get a single blue screen or failure to post with the mobo, I had it up to 520 no problem. The machine boots into windows everytime no matter the voltage but it just isnt prime stable. Below is my pathetic OC attempt. Sorry my post is a bit annoyed but you can imagine how i feel.
this is on a p35 dk t2rs with 1066 tracers
That's really not that bad. I can only get 4ghz stable with 1.4v But at 3.6 I only need a very small bump to 1.250. I could brobably run it on stock voltage, but i'd rather have a tad more power.
Finally got new memory in last night, G.Skill PC8000 4GB kit. Man is this stuff fast. With some additional cooling on the northbridge and RAM I'm testing the limits of stability @ 525 FSB and 4.2GHz. I can load Windows and use it normally, but have not yet stabilized serious benchmarking/stress-testing. Was able to get a quick Super Pi 1M run in though - 11.125 seconds. Everest mem speeds were 8.66GB/s copy, 8.5GB/s read, 11.1GB/s write, and 54.5ns latency. I feel like a little more tuning (and an O.S. reload - thanks to earlier corruption) could get things running perfectly at these speeds.
Unfortunately, I've got to pump some serious volts through the various components even for the relative stability I have now. 1.425 Vcore (1.4 in Windows under load), 2.1 Vdimm, 1.57 Vmch, Vich 1.55, Vtt 1.2375, GTLREF @ stock 63%. Also had to raise tRFC to 55 (all other timings auto). I don't think it's a smart idea to raise any of these voltages further on air cooling, except Vtt. I think I can probably tighten some of the sub-timings on the RAM, since I'm only o/c'ing the DIMMs by 5%.
Anyone else have such luck with this board (or any P35 board for that matter)? 525 FSB has surpassed my expectations. If I can get this to be stable I'll be happy, at least until Nehalem :p
No screenies ATM, I'm at work. Will post tonight.
Sucks that you guys got some :banana::banana::banana::banana:ty chips. It does make that one guy who was crowing about "water cooling = better OC (and 0.9 less vcore required)" look like a total fool I think that was back one or two pages now.
Still amazes me how much variability we have between batches, just 2 weeks after mine.
techguy - yeah I would definitely do an OS reload. When I was OCing with my :banana::banana::banana::banana:ty Q743 chip, I was BSODing and hard-locking all over the place. Pretty sure XP did not like that one bit.
Two q748 samples doing 5ghz+:
http://www.xtremesystems.org/forums/...6&postcount=11
Sadly my q748 isnt a performer either. Needs over 1.4v just to get into windows at 4ghz. Will not waste time testing stability at this voltage, but am content with 3.6ghz at 1.23v.
Heh, well I knew it was bad when I was at 1.36vcore (WIN) and I was still struggling to make 3.96Ghz stable. I mean, even MORE vcore and still not 4Ghz? It truly made me sad panda. Even my current chip is fairly average, but there's just too much uncertainty with these chips to just get another and hope for the best.
That sucks, but you just never know. From your sig, it looks like you have a real nice chip. Nice low volts for 4G.
Yeah, I can get it upto that on my setup no worries, however, I keep it at the settings in my sig because it gives me better memory bandwidth. Try lowering your performance level, at 500fsb it gives me 10.1GB read, 10.6GB write and 9.3GB copy bandwidth and a latency of 48.2ns with my Ballistix 6400 ram.
It seems I've finally found the magic numbers. Though I think I can tighten the ram timings a little. This was at 1.4vcore. I think I might be able to back down to maybe 1.375, but I will play with it and see. I just wanted to hit 4Ghz stable. :)

all chips do 4ghz ?? I need to do 500x8 on my Abit P35 with DDR 8000 OCZ and follow one chip to do 4ghz for a party of my city and ned to know if all E8400 does 4ghz with wc.
or wich step I have looking for.
thanks
i think most of em do it, the best needs less volts to get there
my 745 needs only 1.312 for 4ghz, and some will do it with even less
if you add WC to the equation i doubt you won't reach 4ghz even with a not so much good clocker

E8400 Q748A219
Still pushing higher, orthos'ing 4.2Ghz currently. But here's what she did so far. Lapped and water cooled.
http://3dxtreme.net/other/E8400%20Q7...4050-1.40v.jpg
http://3dxtreme.net/other/E8400%20Q7...104-1.432v.jpg
My E8400 can do 4.05 stable @ 1.26v. I got this from tankguys before they ran out and specifically asked for this batch.
Here's my benchmark.... compare link.
http://service.futuremark.com/compare?3dm06=5704056
500x8 is as high as it goes with 100% stability for me. Finally that G.Skill memory I got paid off and allowed me to hit 4GHz. I'm going to see if I can tighten the timings at all since I'm only running the RAM @ stock 500MHz & SPD timings.
http://img.photobucket.com/albums/v2...an/spi4ghz.jpg
Sorry no CPU-z or memset, this was all I had time for before I left for work this morning.
Still tweaking but looks promising so far...
http://img.photobucket.com/albums/v7...r/d3f304b8.jpg
And so close...
http://img.photobucket.com/albums/v7...r/260040b1.jpg
Only voltage adjustments so far are setting the RAM to 2v and upping the vCore to 1.3 (in BIOS).
Currently testing same settings with a vCore of 1.28...trying to see how low it'll run before upping the FSB again.
More photos sigged. Good job, everyone else!
Batch: Q745A731
http://i228.photobucket.com/albums/e.../Capture-4.jpg
I have a Q743 and it is awesome. It is on air in my HTPC as I type this running 4Ghz (8x500) at 1.25v and in my WCed DFI rig I had it running 4.3Ghz at 1.43v. Could have easily done more with more GTL tuning but I wanted it for low volt 4Ghz 24/7 use in my HTPC and did not want to bork it.
Just throwing this up because it surprised me so.
Flashed to the new Gigabyte F12 BIOS- only apparent change is the ".5 multiplier" option- and was considering where to go next with my chip when I recalled some talk about a "hole" in the FSB that seems to sit around 450 or so.
I wondered how deep that hole might be and decided to try 8 x 500, just kind of randomly picked it out but the resulting numbers had a pleasing symmetry to them...nice round 4000MHz clock speed, RAM exactly at it's 1000MHZ advertised speed and a rated FSB of 2000 even.
Figured it might boot to desktop but not much more.
Well, it did boot and seemed OK so I set up an Orthos run and left to run some errands.
This is what I came home to...
http://img.photobucket.com/albums/v7...r/1cdc6e16.jpg
Note the vCore.
It's set to 1.275v in BIOS so there's some droop under load (Orthos reports an idle voltage of 1.280, so there's a bit of inaccuracy everywhere it seems) but this particular chip seems to thrive at lower voltages.
Very odd.
Also, my temp sensors seem to be "loosening up" or something.
When I first got the chip a few weeks ago, it would NOT read below 35°c, regardless of the ambient.
I froze my tail off with a window open only to see the temp remain stubbornly fixed.
Now, under more normal conditions- i.e., window closed, me comfy- idle runs a more realistic 26-28°c...much closer to what I would have expected with effective watercooling.
Next I think I'm going to try lowering the vCore again- maybe 1.25v- and see what happens.
Meanwhile I'll enjoy the warm and fuzzy feeling that a 500FSB gives me...
EXELLENT CHIP THIER ! whats the batch ??
Stepping: 6CO
Week: Q746
Code: A518
I kinda feel the need to duck when i say this but, I have 2 E8400's:rofl:
Hey I ordered my first one from the egg on Jan 23rd or 4th and I installed it on my P5KE- wifi. Running it with a pair of G.Skill 6400HZ proved to be a match made in heaven.:clap: I tested it with me Evga ultra on the 3D's
I found on the 3D mark's and Aquamark I did better using the 8.5 multiplier
I found on pi that going one to one yielded my best time at a leeser fsb but higher clock speed. My prcessors were bought 2 weeks apart but they were both Q746's and both packed on 1/16/08. Here are a couple results with the P5KE board, This is Air cooled with a Scythe cpu cooler but, I also have a 4 inch squirrel cage fan blowing air through the cooler and over the mem and NB as well. The system stays very cool as my fan is outside till it warms up then it will be in front of the AC outlet.
Here are my pi and AQMK3 results with the P5KE
http://img.photobucket.com/albums/v2...illa/piguy.jpg
And here are my AQMK3 results again on the 8.5 multi. Which yielded a higher cpu score. Oh and the G.Skill just took what ever I gave it!!!
http://img.photobucket.com/albums/v2...lla/aqmk3e.jpg
Then a couple weekds later I ordered again and got another E8400 with the same pack date of 1/16/08 again a Q746
This time however I pulled my Q6600 from WZ-3 and put the processor in this machine. It runs a P5E and is liquid cooled
I also run G.Skill 6400HZ on this platform also. Again simply because it will run anywhere tight and fast!!!
Now this board does not like to run the multipliers nearly as my as the P5KE but, running on the straight 9 multi it will run right over my P5KE
Remember this machine is liquid cooled although with my cooling set up on the other they run nearly identical temps.
here are my pi and AQMK3 scores to compare I used the same 8800 ultra card in this machine to compare the 3D's
first the pi.
http://img.photobucket.com/albums/v2...piagainand.jpg
As you can see it is only about .07 seconds faster but, when you get up to this speed that .07 is huge!!
Check out the Aquamark cpu scores. The P5E just hammers what I could do on my P5KE.:shocked:
http://img.photobucket.com/albums/v2...Zilla/aqff.jpg
For me both systems have been near perfection right out of the box.:up: On the P5E I put in the processor, installed 2 x 250 gig Seagate hdd's set the fsb to 500
fired it for the very first time at 4500mhz right out of the box and installed windows XP-Pro on a fresh Raid0 array and it has run flawless for me.
Both systems are good to go and both run at break neck speeds daily as you can see by my sig where I run them 24/7.
I run a 800GTX with the P5KE-wifi system and the ultra stays home with the P5E. Everyone is happy
Another thing, I have just hammered them with voltage:D with absolutely no degradation at all!! not one bit. If it begins to happen I will let you know.
At my daily clock they are getting hit with about 1.544V. I think I should tell you that I have had my 2.4C SL6Z3 running on 1.662v. for over 3 years and it is still kicking.
I am not afraid of a little voltage........:rolleyes:
WZ
Just got done building it lastnight. My first build. Can't believe how fast it is.
http://img169.imageshack.us/img169/5...lockgj4.th.jpg
I have stuff up my sleeve, so I guess I will let you in on it :D
I am working on a WCing solution for my HTPC that involves me running the Pump and rad in the Crawlspace of my Condo for silence reasons as well as low ambeints even in the winter. Bad thing is I think I need to beef up my RAD from a MCR220 to a 320 or perhaps even a TC PA 120.3 and I ned to get a EK 8800GTS block and I am semi-broke right now.
I will have the solution finnished by the summer heat and I will crank it up for sure. ATM with little in the way of accurate temp reading and my Zipang not getting enough fresh air in my Silverstone Crown, I keep the clocks modest.
I also thing you had a better chip than I did sofarfrome, yours is (was?) a gem ;)
Hey Weldzilla - what is the highest clock you can run on the 2 chips which is at leasst 8h+ Prime stable, and at what voltage?
thks clokker ! eye hopeing to hold out for next stepping but it's getten harder & harder to wait hahahaha those 743's & 746's are what eye have to choose from at my wholesaler TPI Inc. here in phx.
I was able to SPi @ 4.25GHz 1M - 10.656s 32M - 12:31 and some change
However, I got greedy with memset and tried to drop timings too far (or simply did something I shouldn't have) and have either
a) already borked my RAM
b) pushed the chip too far
c) need to reload Windows @ stock settings
I'm thinking I'll try c first before I go out and buy new RAM or a proc. :D
:D

Q745A567
http://i151.photobucket.com/albums/s...m1/4hours2.jpg
what priority should be set to orthos for priming ?
saw people priming at priority 1 when some set it at level 7
Setting a higher priority will supposedly keep a more consistent load. It sets the priority of orthos vs. other applications running in windows. I've never noticed a difference in results. Meaning in my case if it fails at 9 it fails at 1.
Hi all, very impressive overclocks... I just installed my E3110 today. I seen a few posts that do not make any sense to me.... I only ever adjust the cpu fsb... so 8 x 500 would be 4000mhz.... but I seen someone in this thread, running that but getting 4500mhz....
is there some other setting I can alter, to maybe get a better overclock....
my 9 x 480 failed and rebooted my computer, but 9x478 is still running right now.... but I am using high voltage (1.6)....
once I know if it is stable... I will play around, but if I am missing out on something, plz let me knowwwwwwwwwwww
thx
ahhh, thx!
I got mine stable at 445x9.0 (1780QDR -- 4.01GHz) at 1.425v Vcore (1.39idle in windows and 1.36v under load) Runs great, I got a below average batch (Q76A366).. needs a crap load of VCORE to go up from 3.83, which i had running at 1.3 underload..
hallo can somebody tel me where can i find this?..

Thanks. Finally got a winner of sorts!
More results from the same chip:

@ 1.275V I think. I accidentally minimized the notepad and didn't realize :doh:
http://individual.utoronto.ca/bzhou/...303-1.336V.JPG
Finally bothered to write down all of the settings on this one.
Got my e8400 the other day. Its great :D
I have read alot of different things about degrading of the chip. Some pepole say: dont go over 1.4 vcore, some says 1.45 and some says that 1.5 wouldnt hurt the chip.
I would very much like to have the opinion from someone who Knows what he/she is talking about.
What vcore is safe with a good aircooler?
I get my chip totaly stable with 1.375 (bios) at 4005 mhz and around 1.45 for 4200.
Not the best chip, but Im satisfied with that. Of course I´d like to go higher:yepp: , but not of the cost of my new chip..:(
Well nobody knows, nobody knows. If I were you I would stay at 1.375 and 4ghz since you don't really need any more power anyway.
I was testing alittle and noticed that my chip requires only 1.16v running a 3600! And I have it now stable at 3840mhz @ 1.23v. So you can get pretty high with low voltages, 4ghz seems to take more.
Funny, because right at this moment Im experimenting with 3600 myself. Its a good number since 1200 mhz ram speed suits me too. It seems that I need 1.225 vcore (1.192 windows) to get Orthos stable maybe a little more.
You must have a good batch. Is 1.16v your bios or "real" vcore at 3600?
hallo,does anybody have same as my?.. ...Q205A226
pack date is 3.3.2008
you wrote it wrong dude...q205a doesnt exist...read again....
sorry should be q806a226..so?.. :o)
listen i ve got Q806A226 on the box...f...but now i m not sure...i m at work i ll check tonight and let you know...:o)..
i hope that core will be good fot OC... :o)...
nope
q7xx or something, look at box.
Here in Hong Kong, we have Q807A191. ;)
it depends what kind of apps youre running. With 1200 Mhz ram you get really good mem performance, like read, wright, copy and delay.
But in more cpu demanding apps like gaming I´d say that cpu power is more important than +200 Mhz memory speed. Of course you can also tighten the timiming at 1000 mhz if you got good mems, like 4-4-4-8. Mine must be ran at 5-5-5-15 if you go higher than 1069
I can do a 3dmark06 with the two different settings if you like (kind of curiose myself;) )
I´ll be back in about 1 hour....:up:
IVO, this is what a 8400 can do, further test later!
http://i95.photobucket.com/albums/l1...E8400small.jpg
I ll show my but you have to wait 2 week cause my case is on the way...:o)
i hope my processor is near like yours hehe
seems new batch then....
Maybe not the most scentific test, but here are my results in 3dmark06
9858 3DMarks 3600 Mhz And 1200 Mhz Mem 5-5-5-15
10056 3DMarks 4005 Mhz And 1067 Mhz Mem 4-4-4-8
10066 3DMarks 4005 Mhz And 1187 Mhz Mem 5-5-5-15
The answer to your question is: No. If you want to get scores in 3dmark, anyway.
Batch is pretty good but not near the best that have been reported here.
4ghz needs around 1.32v to be stable. And yes it is the real vcore idleing around 1.18 and vdrooping to 1.16 in load, I was quite surprised myself to see it run at so low voltages.
Edit: The batch is Q746A349
