1.248 for 4.1, ...I can just boot into windows with 1.25 at 4ghz. Does not look like they binned that E8200.
Printable View
yep, thats why I said it was not binned, VID's that low I have seen more often on E8500, less often on E8400, kind of surprised to see on E8200.
Anyone lap one of these yet? And if so, what were the results?
i did but never used it stock :D
how much is the gain lapping an E8400?
Gentleman!!! GREAT NEWS!!
Setting GTL levels DOWN just got me over the 3.96ghz spi 32m stability hump!! I'm still at 1.425v and haven't had to change that, and I gained a decent amount!!
I'm not only happy that I gained a few mhz... I'm happy that I figured out WHY this chip couldn't get to 4ghz.
Right now I just passed 4.17ghz spi 32m!!! This GTL level RLY helped!!
I saw C-N's post of setting all three GTL REF settings to 60, so I copied that and viola.
Now, I do have the other GTL buffer strength sset to strong (choice are strong and weak), which is default. Dunno if I should mess with that as I don't know what it does. Maybe if I tweak GTL ref more I'll get an even better OC, but I've no clue what it's truly doing and which plays the more important role.
Here are my settings right now:

My next concern is why is my idle temp not as low as most other people when I'm on a D-Tek Fuzion with a custom mobo back plate mount and liquid metal TIM...
Sorry I didn't get it while it was on LOAD temp... something came up and couldn't take screenshot in time:

Try 8.5 x 490 - 500 and set gtls to 59/59/59. Try this and dropping the vcore amd PLL too.
anybody here with an e8400 batch Q746A446? how's it clocking for you guys?
dropping the PLL?? i only raised it up trying to test things out. i probably didn't even need to. can it be HARMFUL to have it raised a notch over stock?
hopefully i'll have time to play more maybe this weekend. almost 4.2ghz is definitely a good start for tonight, plus i have another e8400 sitting on my desk that i wanna throw in VERY SOON, like this weekend!!
I'm going to be extremely busy with worth the next few weeks starting Monday. I work I.T. and the company I work for is sending me to a potentially HUGE client. I'm supposed to represent our company and not that I'm nervous, but I gotta get my sh$% together. The commute and hours are adding approx. 3 hrs to my day!! :( Which means... less OCing for me.
You don't need that PLL for what you're trying to do. 1.55v is fine.

I caved and started more testing :D Orthos Blend for 5 1/2 hours at 4233 with 1.31v load. Testing 4275 now,same voltage. Will post a screen shot later :)
Larry
All of you here have good chips :) What's impressive is being able to do Orthos with such low volts.
Thank You :)
I am using the D-Tek Fuzion with just a 1/8" thick Oring. I chill my water and control it digitally at 50 to 53F. It helps to keep the temps down :D
Water cooling setup is a Dehumidifier with the Rad dropped in a Rez with about 2 gallons of water in it, as well as my Ehiem 1260 pump. I have a digital controller which is set to turn the dehumid on/off at my specified temps.
The whole setup is about 15' away from my computer,(hence the 1260 pump), in another room,( water lines run behind my Bath Tub and thru the walls) :D When I built the upstairs addition, I set it up that way with an alcove for the dehumid/res so it is tucked away out of sight.
I run the lines to the Fuzion, then to my MCW60 on my vid card, then back to the Rez, works out pretty slick and I never hear the dehumid at all. Been running this cooling setup for about 4 years now. I could run the water colder very easily, but then I would need to insulate all the lines/blocks etc. Too much of a hassle for how often I change things, so I found that 50 to 53F is a good compromise to no insulation in the actual computer, and No condensation at those temps.
Sorry for the Long winded reply :)
Larry
Nice! :clap:
I'm very interested in your bios settings, especially the following:
Voltage Setting Page
CPU VID Special Add.......................+ xxxmv
DRAM Voltage Control......................2.xxV
SB 1.05V Voltage..........................1.xxxV
SB Core/CPU PLL Voltage...................1.xxV
NB Core Voltage...........................1.xxV
CPU VTT Voltage...........................1.xxV
Clockgen Voltage Control..................3.45V
CPU GTL1/3 REF Volt.......................0.xxx
CPU GTL 0/2 REF Volt......................0.xxx
North Bridge GTL REF Volt ...............0.xxx
OK, first off my vid reported by Core Temp is 0.9875v so my Vid special add is +262mv which gives it MY voltage, seems the vid+ the add will be different with different vids.
DRAM volts are set at 2.075v
The rest of the volts are Stock, no changes, tho I am testing 61/61/61 on the GTL's but for all practical purposes, I run them at 67/67/67 which is bios defaults.
Hope that is what you requested :)
Larry

Yeah...only 5 mins but to even be booting at that voltage? That's nuts. Still waiting to see the first 4.3Ghz with < 1.3v, I think that guy has a great chance then.
Thanks! @ dark22, Very nice chip there :)

Question; dark22 why does Orthos say 4499 and core temp/cpu-z says 4000? A Glitch maybe?
Larry
Yeah thats a bug in windows , and other programs, they are reading only the defualt Multiplier made by the cpu nomather what plier u use, it reads in like that.
As moving to newer weeks i thing this Wolfies become better regardless E8x00
for 4.5 Ghz it needs 1.41 and for 4.3 ghz 1.375 to be stable but i want to leave it for 2-3 days at 1.2 volt so it will learn to operate in low voltages...
@ Mykou Sorry, I have not used a Heatsink for a cpu in years :( I hope your new chip runs fantastic!
@ dark22 Your chip is very similar to mine, I have run Blend at 4275 at 1.34v, but cannot run 4275 and 10k fft's in place for long enough yet, so I havn't tried higher yet. Great chip you have there :D
Very nice indeed. :)
Wasnt sure where to post Xeon results, but here goes.

can you post a screen for 4.5 with 1.41 vcore plz maybe with cpu z and 30 min orthos...like this(4.3 ghz and 1.376 v):
http://www.pctunerup.com/up/results/...518_spi33m.jpg
for 4.5 im still testing but i am pretty sure that it need more than 1.41....
DAMN dark22 thats gotta be the best chip yet !!
Here is some new core temperature monitoring software from unclewebb called Real Temp. It reads the DTS data exactly the same as SpeedFan and CoreTemp do. Its still in beta but hopefully will be released soon. It appears that the new speedfan 4.34 beta 40 uses a Tj.Max of 95c as does Real Temp. Real Temp has other features but I will leave that for the author to explain.:D
@Ron 61: where to get RealTemp app?
Sorry, I cannot distribute as I am just testing it for unclewebb. unclewebb says it will be released soon.:up:
Edit: Here is original post http://www.xtremesystems.org/forums/...postcount=1808
i was wrong... it doesnt need 1.375... it needs 1.36 for 4320Mhz...
the problem is that on that frequency my temps are very high!!!
79C i thing is to much for that cpu...
i also tried at 4.5Ghz with 1.4 but is not stable, i thing because of temps...
i saw 90C and i dont feel comfotable with that...
until now i havent change GTL settings but i think that i will need to
and also better cooling because here in Creta the weather is hot...
http://i96.photobucket.com/albums/l1...untitled-6.jpg
All 99% of people do around here is run SuperPI and various other benchmarks, complain about temperature software, throttling processors, idle temperatures being out to lunch as well as b-i-t-c-h about the sticking DTS sensors in the new Intel 45nm chips. :D
I combined it all, somehow, along with my experiences with pointing an IR thermometer at my bare E6400 and E8400 CPUs and have created a new program called Real Temp. The swiss army knife of temp software.

I finished the data logging feature tonight and after I write a pile of documentation for it, it will be ready for download tomorrow.

dark22: may i steal your cpu?
mine don t have temps issues but isnt stable 4.5 ghz with 1.40 v anyway.... (I THINK EVER TO NORTH POLE ISNT STABLE by those vcore) it does 24 min orthos at 4.283 ghz with 1.376 v(6 min it did at 4.33 ghz LOL) i didnt change gtl setting too...i think ur is so hot because have lower VID than mine
http://www.pctunerup.com/up/results/...448_spi33m.jpg
i went out and i left it for a little longer...
i think at ~4400 Ghz it can be stable with 1.39-1.4...
about the temps probably coretemp it is not reading well...
i am waiting for real temp... to test again...
http://i96.photobucket.com/albums/l1...untitled-7.jpg
Hi everyone =D.
http://img528.imageshack.us/img528/7...rclock2we4.jpg
I went for 4, but I couldn't get it stable, so I'm going to give it another try tomorow =D
yes coretemp and all the software not reading correct...but 81 anyway i think is real hot...i think 4.5 will be stable at least at 1.44-1.45(i mean 500x9 not 490x9)...mine after 11 hr show 66 C core 0 and 62 core 1
http://www.pctunerup.com/up/results/...1_orthlong.jpg
Get everest, it reads Wolfdale chips correctly. Atleast on mine.
i agree the last everest read very well my 8400
when overclock i just look everest to see all right ( or not)
I've been doing some research on the temp confusion we all seem to be having with the wolfdales. Coretemp thinks the Tjunction max should be 105c
but from what Im finding from reading the Intel e8000 datasheet Tjmax should be 92.4c, this calculation is based on Tcase max of 72.4c + Ttrip of
20c over Tcase which = Tjmax of 92.4c
Just thought I should put this out there.
my everest 4.20 reads the same like coretemp...
Everest Ultimate Edition v4.20.1292 Beta Multilenguaje
read very fine my 8400, no troubles.
Man my first opinion 1.45@4650 is close enough.
I like that you love your cpu (φτου μην τον ματιάξω)
Are you on air? Mine does 4500@1.45 all benches but orthos tested only for 24/7 setup 4050@1.3V
which is a good cpu amongst others just think that for your cpu how excellent it is. It reminds me of
my previous E6750@1.3@3.6 on air.
My Everest Ultimate and CPUID Hardware Monitor both show my idle cpu temp at 28C @ 4.1GHz, while in the bios the cpu temp is 32C? I would probably believe the latter, and add 4C onto the Windows temps.
Some other posters have confirmed that thermal throttling starts at bout 95C, which would bring the tjMAX of 105C into question. I guess we could then add 10C to the core temp readings in Windows, also.
... When your in BIOS the CPU is under load... fail :rolleyes:
Not a very high load, but enough to bring the temps up 4-8 degrees.
everest ultimate latest version beta read the same temps of coretemp..isnt correct IMHO
thx Spyrus :)
i have some issues with my mobo P5k Green... it is degraded...
i cannot be stable at 500 fsb... crap...
I also cannot give more than 1.5 volt on the northbridge... when i put more no boot...
so i am trying at 4410 mhz with 1.37-1.38 but i cannot make it stable...
the same issues i have also at 4000 mhz... it is not stable know...
but at 445x9 it runs at the same volts... 1.2...
so until i will find a desend mobo i cannot search for higher stable frequency...
What's the best budget board for E8400 overclocking? I don't need RAID, or SLI, and will be using a Tuniq Tower heatsink.
If anyone has figured it out, I'd love to know what GTL REF voltages work best with what VTT... like maybe a list or something.
It's taking me forever to figure it out, but for me with 1.12vtt I was getting similar results with 59, 60, and 70... as long as it wasn't set to default b/c default was the worst by FAR.
How do I adjust GTL/ VTT etc on my board? There's no option (Giga P35-S3)
Can I do it via software in windows?
I'd love to get the GTLs figured out myself. I'm just having a heck of time trying to get much over 500 fsb out of my setup. It could be the board I suppose.
Anyway, decided to play with the small ffts today. Much tougher to get it to run. This is the best I could do at 1.36 vcore. Funny thing is just one more on the fsb and it wouldn't go more than 30 sec. I'll try playing with it more later.
Real Temp 1.0 has been released which properly supports these new E8000 processors. I've started a new thread over here:
http://www.xtremesystems.org/forums/...d.php?t=179044
Comments and general abuse for telling people that their cores are not running as hot as they think they are, are sort of welcome. :D
For me setting GTL to 61/61/57 allows me to run 4.2GHz Orthos 8 hours straight :up:

Thanx! I'm quite happy with it :)
hmm weird, I can do 4.1Ghz at 3.12v but 4.2 seems so hard to get stable without a large jump in vcore, which is annoying.
http://img209.imageshack.us/img209/4913/411312veb4.jpg
Hmm, I think you could try 8.5x and a smaller jump in vcore, and see what it can do at 4.2. I have better luck keeping voltage low with 8.5x495 and setting gtls to 59.59.59. It's worth a try.
It's not that much to tweak. What are the options?
If it's anything like my board, you only have 57/61/63 and 67 for the CPU GTL's. NB GTL's are only 61/67. I think his board may be the same, not sure tho. Kinda lame to only have those options, perhaps in time with newer bios's....
Larry
Yes, I meant that suggestion for him. I suppose it can vary from bios to bios. What's your multiplier and FSB termination setting Big Lar?
Reason I ask is that I was able to get stable at 4.2 - 4.25 using less voltage with 8x and 8.5x and setting gtls manually to about 59, than I could with 9x and gtls a little higher.
My current 24/7 is 8.5 x 500 with 1.3vcore. Similar to yours, but for my setup, I'd need a little more juice at 9x.
I'm at 9x470 right now. VTT is still 1.1v, and NB is 1.35v.
I'm waiting on a better bios to come out, I have run both of the newer 1's for this board, but they are both flakey with 8.5 or 8x multipliers with higher fsb. The original bios is the 1 I am running right now, it is the most stable for me, but does not have the option for 1/2 multi's like the newer 1's do. I am patient...
Larry
i have a noob question
gtls, do i set them higher or lower to clock more?
I run my CPU and NB GTL ref at .59 and.61 on my P5K prem which helps with high fsb.

VTT 1.50 Vcore and e8400 at 1.71, much i know but stable and very cold
only 49 c in core 0 and core 1.
with more time i will post more images and benchs.
