My e6420 arrived today
L704 A885
pack date: 4/11/07
hope it's a good over clocker =D
too bad my system won't be up for another 2 week hehe
Damn it. Dnottis you have your 709 up to 3.6 with relatively low voltage, yet my 709 A5xx needs a whole lot. That sucks.
Will do the vdroop mod to see if it helps, but I doubt it.
Cheers,
Mike
Got my e6420
L702 stepping and package date of 04/13/07
So far so good, 3.2ghz stock volts :)
is that Orthos stable at stock volts? I can boot into Windows at 3.2ghz on stock volts and run Super Pi. Orthos stops after about 20 seconds.
Had a chance to do some more testing today:
http://img2.freeimagehosting.net/upl...434d78456d.jpg
Yea I got really lucky with this one. On the DS3 it only needs 1.40v actual and on the vdroop modded p5b-d I need 1.47v. I'm trying to break 3.7 orthos stable now for the OC database on Hardforum. I get about 2hr 30min in and it reboots on me. Jumping up the volts to about 1.55v actual its looking good so far, but I need at least 4 hours to prove it's stable.
24/7 will be 3.6 @ 1.44v tho. I just reworked my loop and put a D-Tek Fuzion in to replace the original Apogee I had.
http://www.3dxtreme.net/other/E6420%...0/IMG_4231.jpg
Same thing happened to me.
I also had my voltage where you're at right now and Orthos would die at the 2.5 hour mark.
Bumped the cpu voltage up to +.87 and did a 10 hour Orthos no problem.
I can run Super Pi at 1.42v @ 425x8 -- but Orthos craps out in about 10 seconds. My guess is I would need about 1.5v to be stable at that speed.
dnottis: Nice rig.
Sure enough Orthos stopped after about 2 hours. Gonna give it a touch more and try again tonight.
Here is what i am confused on. I thought the L6 meant it was manufactured in 2006. I have a packing date of 5/11/2007.
Ov3rclock3r you have a L7 with a packing date of 4/13/2007.
Just curios as to how this could be. I'm thinking the L7 or L6 doesn't necessarily refer to the year it was manufactured.
@Grips, what's your complete FPO/Batch number? And if it's a SL4AT or not. Thanks...
L650C690
Pack Date: 5/11/07
too early to tell. I'm still in my first week with it. Considering it's likely to be stable at 3.2ghz (from 2.13ghz) with a little over 1.4v i would hardly say i could tell someone to 'stay away' from it. For what this chip cost me i say i got a hell of a deal. :)
Gonna let orthos run overnight tonight. I'll post the result before heading out to work in the morning. It looks like voltage is at 1.42v now. Been running orthos for about 15 minutes and max cpu temp is 50C(using a scythe infinity/cpu not lapped).
You and I are in the same boat GripS. Looks like you gave it a little bit more juice--and I'm guessing you'll be stable now.
Your temps are a little higher--I'm running a Thermalright Ultra-120--and the weather hasn't been very warm (for summer) in the last couple of weeks where I live. My temps max at about 46C.
My stepping is L651B--it doesn't look like there's a lot of difference in our chips.
To jcniest5:
I wouldn't say they are bad overclockers at all. I would actually say they are average to above average. I'm pretty sure I could get 425x8 (super pi was fine at this speed) Orthos stable out of this chip if I want to give it the juice--but I'm happy where I'm at right now. I've seen posts with 6420's that couldn't get 375x8 24/7 stable no matter what voltage they threw at it.
Sure you'll always see posts from users who get crazy clocks--but that sometimes takes a ton of patiences and many RMA's to find that one golden sample.
If you're in the market for a sub $200 chip--the 63-6420's are still an unbelievable value.
So far so good at 3.2ghz/1.42v.:D I think i'll let it continue to run overnight before going for more.

Any E6420 L710 that OC's well?
Didn't tested yet , but i'm not expecting much:shrug: :down:
I have one, a L710 from SLA4T.
At first wouldn't go over 2.8, but now I'm at 3.2 (1.4-ish v), gunning for 3.4.
It loads into windows at 3.4, but not orthos stable yet...
Upping mem voltage got me further, and allowed me to drop Vcore (from 1.45 to 1.4) but this coincided with a new PSU, so maybe that's also part of the reason, although I wouldn't understand how it works exactly...
Take your time with it... and configure your mem by hand.
Changing from LTD 5 to 4 also helped me some (but mainly on the 2 => 4 gig prob).
Oh yeah, and up the NB, but make sure to have adequate cooling on it... I'm at 1.5, with a TR HR-05 on the NB, and a TR HR-05 SLI on the SB in a P180. Doens't do much on the SB, but to hell with it... ;-)
Other questions, just shoot!
GL with it, and let us know :D
My E6420 finally made 3.7Ghz Orthos stable. Changing out the block from Apogee to FuZion helps temps as did changing for Thermal Take fans that max at 95 CFM, on a fan controller about 75%.

:clap:
Gr8 work dnottis.
hope to post some 3.4 on air soon myself...
Passed orthos for over 9 hours at 3.2ghz on 1.42v. Gonna try for 3.4 tonight.
dnottis: NICE!
Very nice Dnottis :)
Here's mine:
http://img367.imageshack.us/img367/6...3904ol5.th.jpg
Using P5B 1.04G with 1202 BIOS, using all auto voltages except 2.1V Vdram, I pused the FSB up to around 375 (my Corsair 6400 still well below its rated speed) before it started giving me problems. So, I upped the Vcore, the Vnb, Vfsb, all the settings up to 2nd highest. Got to 380, but thats about it. Wont go any higher.
I heard about some overclocking "hole" between 360 and 400, and that 1333 bootstrap takes effect >400, so took the big leap of fait and tried 401 and 410 to no avail.
Perhaps reached the limit of this little CPU? Tried all over with 6x multiplier, and got to about the same place, 380 fsb, no more.
Tried desperately randomly toggling settings like static read control, and TM... nothing.
Anything obvious you guys can think of that could be causing this?
well, been working a lot on this one, and it won't be my 24/7...
vcore and nb needed a HUGE bump for 3.4.
had to up vcore from 1.37 for 3.2 to 1.525 and NB 1.45 => 1.55...
here's the pic and the system :D
greetz... r0n1n
It might be cause you've got 4gb there. 2gb should be stable with lower volts but dont quote me on that :)
well, it's worth a shot, just for the heck of it :D
will try it out someday, thx for the tip ;)
Does anyone know anything about the L642G043 6420?
http://img527.imageshack.us/img527/7411/32ghzfu0.th.jpg
Volts : 1.3v (lower than stock)
3.2ghz fully stable with ram 1:1 400mhz 4-4-4 2.0v :D
You can see the orthos loaded temps in that pic^^.
Here's TAT temps:

Very good cpu imo :D
dude that's freakin awesome! You got a sweet chip there.
What kind of cooling are you using? (i'm assuming water by your avatar)
What is the max you have gotten your chip to do on stock volts?
I wish it was a rule to have a sig in this forum. What are your system specs?
I am using the infinity as well. I can't believe you are getting such low load temps. Must be real cool in the room or you have an air conditioner in your case:) . What about the mobo and RAM? What are you using?
Hey guys, how hot is your NB on your P965 when running stock 266fsb, and when overclocking (ie 400+)?
Even at stock mine is certainly 60C+ (scorching to the touch)...
i have also an e6420, it's L652Bxxx, and it does 3200 @ 1.39v on bios, 1.36~1.37
idle on windows, and 1.35 load with orthos small ftt, reported by uguru.
i have an abit ab9 quadgt with some cheap 2gb ddr 800 modules left on auto,
vmem 2.125v and vmch 1.3v, all rest @ stock.
happy with it .
Got my E6420 today from EGG HEAD, bought this bad boy just so I could get sideways with it and rape the livin be jesus out of it and make it scream for mercy! Just a fill in in until price chops so I'm gonna get mid evil on this biatch!!!:slapass: :oscar:

- temperature reach 70c rendering Playstation2 games... need better cooling than stock....
Fedex guy just dropped mine off, seems to be from a good batch, will post some results later with stock cooler, than Ninja.
Just got myself a E6420 batch code L649Hxx..pack date 05/09/07
Orthos blend test@410X8 = 3.28ghz , 7hours+ fully stable..
Vcore at 1.29v at bios...Bios set@ 1.325v..others at stock voltage..vdimm@2.0v
How did your chip do man? I just got this in for a clients pc, the mobo i'm sticking it in dosn't have crap for OC options so I won't really be able to tell what it'll do.... L704A882 .... Hahaha very close to yours.
If yours clocked well, i'll order my customer a diff one and keep this one :D
evoic..wats ur actual voltage?
I've had 3 DS3's a P5B-E and P5B-deluxe and the best thing you can do - remove the NB sink, clean it apply AS5 or ceramique - reinstall and add a 50mm fan to the top. After that they just barely get warm and you wont need to pump the NB volts up either :)
One of my DS3s needed mad NB volts and was hot as hell, like 50 @ idle. I did the above and it was 35 idle and 40 load afterwards and went to 507 @ stock volts :) Now I dont even bother running stock, I immediately pull it, clean it and fan it.
Btw my L709 can run to about 3.4 @ 1.35 volts orthos stable :D, 3.712 is my max orthos right now, 3616 is my 24/7.
On the run in the screenshot, the actual voltage is 1.525v.
I have the worst vDroop in the history of computing.
Well......not quite......but pretty bad.
The upside: I can never feed too much voltage to the CPU. The BIOS tops at 1.6v and the most I can get from that is about 1.55v actual, which drops another 0.005v or 0.01v under load.
The downside: I may actually never know how high this E6420 will go.
The downside Part Deux: The NB max volts in the BIOS are limited to 1.4v, which also denies Max OC attempts.
The highest I've gotten into Windows on with this Mobo is 3580Mhz.
here is my result
E6420 _ week L709A515 @3783Mhz 1.65v
http://i163.photobucket.com/albums/t...untitled-4.jpg
@3200Mhz 1.38v _ 26hr+ orthos stable
http://i163.photobucket.com/albums/t...p/64203200.jpg
Nice clock. I doubt that CPU will last long with that much voltage going through it though. You must be using some serious cooling on that for a load temp of 37C.
Got the L651B
3.2ghz @ 1.350v Orthos temps are not higher then 50c :)
3.4ghz @ 1.450v Orthos
3.5ghz @ 1.525v Orthos But gets to hot with scythe infinity.
3.6ghz @ 1.600v Bootable and SuperPI (diddent try Orthos on that voltage :p:)
for benching i use 3.4ghz (3dmark)
I am running 3.2ghz with the ballistix on 500 4-4-4-12 2.15v 24/7. Works fine for me :) i am happy with this chip for now. Next cpu will be a Q6600 G0 :cool:
Thanks for sharing the clocks. because of this topic i get a 51B myself :D
Sorry for bad english.
Would it be fair to say that diminishing returns really kicks in at around 1.45V?
I've read that particular old batch numbers are good OC. But, Goofisch and many others have various otehr batch numbers which are doing really well... has me wondering if its just random luck of draw.
Wow.
Are you sure you've exhausted all options?
The 680i should get you 450+ FSB and the cooling equipment you have should make it safe to pump enough volts into that core to definitely get a higher stable clock.
Unless, of course, you have a dud.
If that's the case - I'd sell it before the price drops and get a replacement ASAP !
Just started playing with a 6320 L709A. Running orthos for 20 min 3300mhz 1.32v watercooled so far :) will upload screenie when i finnish testing:)
L651B
24/7 (might be able to back off the cpu volts a bit--still need to test). CPU temps are that high because we didn't turn on our air conditioning and it was 80F in the room at the time.
http://img402.imageshack.us/img402/8...7ram21vei6.jpg
Suicide run--not Orthos stable at all.
http://img505.imageshack.us/img505/6...iderun1bf8.jpg
Yes this is the same system. The wallpapers and SG are different because the suicide run was taken about a week ago. The 24/7 ran last night.
Yes. It does appear that it's safe to say there are no more REAL good overclockers out there by a particular batch. It does seem to be a real crapshoot with the latest run of processors. I'm pretty happy with the 3.2ghz i have stable on 1.42v. Not quite the 3.6ghz that i was hoping for though.
Nice results guys. Pitty i have THE worst 6420 to ever be produced. I cant get anything over 2800 Orthos "Stable". 400 X 8 @ 1.51 REAL vcore is unstable :mad:. My board (p5b dlx) has massive vdroop so ill whip out a pencil soon. But i can break 11100 in 3dmark 06 with my gts so its not so bad.
I assume that you've already tried upping other voltages too? maybe a bit more NB juice, or mem volts could help out. I know it did help me, but I'm on a P5N32-E sli plus, which is a board that needs a LOT of tweaking (just like a lady...)
I'm now also stable at 3.2 for 24/7 @ 1.375, and was able to load windows up to 3.6 @ 1.525. Not orthos stable though. But I read some v's of over 1.6... maybe should try that one day :D
cheers, and happy oc'ing ;p
hey guys..
my E6420 @ 4 Ghz aircooled (1.6v)
http://valid.x86-secret.com/show_oc?id=206625
Hey guys!
Just reached 4000mhz with my e6420 on 1.55 vcore unstable though.
Is it safe to run 1.55-1.6 if i dont use it 24/7? I use watercooling.

I would say that you're looking at the life expectancy of your CPU dropping from 12-15 years......down to maybe 7-9 years.
These are numbers that I'm completely pulling out of my ass, mind you.
But don't be surprised if they're close, and even if they're not, you get the basic idea.
Will your CPU explode after 6 months of running like that, no.
Will it possibly / probably diminish the life expctancy, yes.
More than voltage, the primary thing you, me, or any user should be concerned with is heat.
If your system & CPU stays cool at 1.6v (35c or under idle / 55c or lower under load) then I wouldn't worry about it at all.
By the time that chip finally kicks the bucket, you will have purchased his great-great-great-great-great-great-great grandson chip.
The Intel Ocho-Quad Duo at 10000Mhz.
8x4 cores x's 2 Chips mated together in Intel propietary packaging with each core operating at 10Ghz.
How much voltage do you think your CPU will take then? :D
@evoic
good point lol :rofl:
i finally made past 500fsb guys(aircooled), dont lose hope on your e6320 & e6420.
what kinda volts ya have to put through it?
@grips,
1.5vcore
2.4vdimm
orthos stable?
ran superpi, succeeded. no orthos yet, will post when im done.
@Deimos,
DFI P965s dark.
Mine is scheduled to arrive on Thursday.
I can't WAIT.
This eVGA 680i LT is hitting the brakes on me around 440Mhz.
I'm nearly positive that eVGA designs the BIOS to not allow extreme FSB speeds because they want to keep their non-LT version at a premium.
As a case in point, my original (P02) BIOS allowed 1.5v on the MCP.
When I updated the BIOS and flashed to P04, the option was removed and 1.4v was the new max. :mad:
New E6420s and conclusions.
Mobo fsb limit does certainly exist.
CPU fsb limit also undeniably exists.
CPUs from same production week can have vastly different OC.
How do I know this? New made in Costa Rica E6420 fails to POST at 440fsb.. but sure enough powers through at 430fsb (all lowest voltages!!). Another E6420 with identical setup started getting unstable >370fsb. And with lots of voltage for everything could only get it to run up to 390fsb. Another 0709 Malaysia has no problem with fsb, but fails to reach 3.1Ghz like its brother.. in fact only 2.9Ghz...
so far Costa Rica for teh wIn :{/
E6420@3945 Mhz with Andy Samurai :yepp: , 2x1024 Umax 800, DFI Infinity P965-S, air.
dsaraolu.......3945Mhz on air is SICK.
I'm fairly sure there's no way you're Orthos stable at that speed, but I would love to know if you're able to beat the 3720Mhz that dnottis just put up below your post.
.
.
could be either the CPU or the mobo limiting you to 445FSB.
3.9Ghz on air? Dont feel upset. I gurantee you that 95% of chips out there wont even come close. There are certainly more chips out there which wont see the light of 3.0Ghz on air than the 3.9 variety.
I've already tried several E6420.. but in the end my "treasure hunt" for the golden "cherry pick" CPU cost a lot and didn't get me far. I'm sure it would be much easier if I worked on Dell assembly line and got to try out 1000 chipss ;)
My QuadGT can only do 444 mhz. Anything beyond that is just unstable. Pretty sure my E6320 can go a little further, but I think my board is holding me back.
I'm at 3.4ghz right now with stock 1.325v loaded. Orthose stable, I'll post some more pics when i'm at 3.5ghz stock volts or 3.6 :)
@dnottis, dsaraolu,
nice clocks....keep em going guys...
I just recieved this batch 3717A922 from newegg. I can't find any information at all, I can't even find another stepping with a number as the first digit. I am using a 650i MB with this chip and so far its at 3GHz, but I havent loaded windows yet so I can't tell anything yet. Anyway this is the rig.
6420 3717A922
MSI P6N-SLI
Balistics 6400
BFG 8600GT
Seasonic S12-600
I will post more when I get some testing done.
Just a follow-up, I don't believe my chip is the problem, but I can't start testing that theory until later this evening.
Mine is a L651 B325 Batch. (Mfg'd Late December of 06')
These have been known to be good clockers, but the board needs to be able to scale on the FSB because the chip is limited to 8x multi.
I'm praying my P965-S Dark let's me find out once and for all.
Also, just to answer the post from Deimos, my E6420 will do Orthos stable 3200Mhz at stock voltage.
I can run it up to around 3.4Ghz (not Orthos stable, but Windows boots) before I have to start bumping the volts.
Dang all you guys are getting great overclocks on your e6420's.
I'm stuck at 3.4GHz with 1.44vcore with vdroop mod on my p5n-e sli board (fsb 425MHz).
I'm doing this with 4GB of ram (OCZ Titanium PC6400 @ 5-5-5-15, 2T, 2.1v) @ 1020MHz.
Having a hell of a time trying to get my Ultra-120 properly seated on my cpu.
I can get it on just fine and it makes good contact, but it's just getting the dang thing on without moving it around too much so the thermal paste stays nicely spread out.
When I remove it to check for contact I see a lot of the thermal paste is not evenly spread out and has bald spots where it's just bare heatsink and cpu contacting without thermal paste.
Tried spreading out the thermal paste today and making contact the old way instead of using the Thermalright way of putting a thin line down the middle of the cpu.
I will report back with temps.
I'm hitting 58 celsius at peak load with orthos priority 9 and small ftts to stress the cpu.
Ambient is pretty warm I might add, but I wish I had four hands so I could hold the heatsink steady with two and screw in two bolts at once to balance things out without disturbing the thermal paste upon installation.
*sigh*
Anyways, I will report back after some more temperature and stress testing.
Going to try for 3.6GHz.
Cheers,
Mike
just got an E6320 L709A344
probably run it on my P5K deluxe and under the Vapochill.
Just got a E6420 L707A751, have it running 1333 FSB now with stock cooler/volts. Orthos been running around 30 minutes, staying around 70~72C. Still waiting on the MM case before i put it under water.
I'm running at 8x333 :/ I'm pretty sure my cheapo memories won't allow me to go much farther.. but I'm happy (this is my _first_ ever oc experience:) )

Edit: I'm running 1500 FSB now (3.0 Ghz), 24 hour Orthos stable 1.32v in BIOS. The above post is wrong, I had volts set to auto, that's why my temps were hitting the 70's. With volts set at 1.32 i'm topping out at 58C. This is looking like it'll be a nice chip. Will post more after I top it out.
SO.....
I found out that it's not my Mobo.
I get the same limit when using my 680i and also when I recently tested a DFI P965-S Dark.
It appears that my E6420 has a wall right around 445Mhz.
I wish there was some way to overcome this, but as it stands......I don't believe it's possible for me to go higher.
:(

My E6320 do 7*435= 3,045Ghz stock volt And only 23c with a 9700 zalman
But the party end at fsb 440*7 = 3,08Ghz.
Tryèd a freinds E6600 6*550 = 3300 no problems.
