I can get 3.5ghz out of my E6420 if I jack up the juice beyond 1.4V :D
I'm at 3.6ghz now at 1.425v loaded, Orthos stable. Not bad :)
Nope. Not bad at all. Freakin awesome actually. If we could only see that screenshot you keep promising. :rolleyes:
Seems there are a LOT of claims here without any proof. :)
@ Nanok: Please tell me you are not complaining about 1.2ghz above stock on stock volts.
E6320 @ 3.2ghz 460x7, 1.47V. I'd link a screenshot, but my DFI P965-s literally caught on fire, or at least a few resistors did due to water splashes that I failed to see. Just ordered a P35 DS3R.
Seems like overall the E6420's are hitting very good clocks. The E6320's are pretty hurtin' though.
Can't wait to get my mobo replacement and see what my 6420 and do. Had a faulty mobo that kept trying to boot from my floppy drive no matter what boot order or BIOS configuration I used. Couldn't install windows from my CD drive because of it lol.
Anyways my stepping is L709A510 and judging by the steppings here I should have around a 3.4-3.7 chip. WAHOO!
Anyone see the table with confirmed chip speeds over at HardForum? http://hardforum.com/showthread.php?t=1138241 Looks like the L709's lead the pack of the E6420's.
I went from a cpu that wouldnt hold 3.2 stable at any voltage to this! All thanks to my new lovly HZ's! :up:.
I got my P5N-E today and started to test my 6420. I got a dud 3.2@1.53V, I didn't test it for stability. I just reduced the vcore to 1.42 and ran it at 2.8. Its been 5 hrs stable so far.
My E6420 is @ 3.2 with 1.37v. Haven't really needed to go any higher as all my games are screamin' fast.
Yeah i've been meaning to update that. P5B Dlx (With THE WORST vdroop you've ever seen. Im talking like .08). E6420, 2gig of Gskill HZ 6400's, Asus GTS (320mb) at 675/985. Tuniq 120+ in a Armor with a OCZ 850w. Temps are sub 50c in a descent ambient of 25+.
But yeah as i said before i couldnt get anything over 2.8ghz stable before..... Might be a fsb hole in my board / chip or something but this baby just loves to clock. :shrug:
Just installed my E6420 OEM yesterday.
MB is P5N-E SLI with two Ballistix DDR(2)-800.
Have done minimal testing/OC and settled for 400x8 @ 1.3750 (1.34 loaded).
Seems that the chip has "a wall" here as 412.5x8 will not boot at 1.425.
As of writing this I have set a "standard" for my systems to OC up to a FSB where miminal VCore is necessary.
Many chips / many systems has shown (for me) it's not worth the effort when VCore has to be increased just to get a few hundred more Mhz for "suicidal screenies" and single core benching. :)

Just did a build last Thursday/Friday using an Abit IP35 Pro and an e6420 (I'll have to get the stepping once I get my case fans in to add WC). On air, stock voltage of 1.32 volts I am easily hitting 3.2. I figure 4g is a possibility given that my WCing setup takes another 10 - 12C off the temps which on stock air cooler are 31C idle and 53C under max load (Orthos, Prime, SuperPi, and 3dMark06 running concurrently for 2 hours). I bought a DD Torture Rack and have 2 fans on it now. Once I have all 8 fans running, 3.6 should be easy to get, just have to see what the "wall" is.
Specs:
Abit IP35 Pro
e6420 @ 1.32 v
Corsair Dominator 8500 2GB @ 400 x 8 and 1.9 v
eVga 8800 GTS Superclocked
Antec HE550 PSU
DD Torture Rack
Waiting on the tarmac:
Swiftech Apogee GTX
Swiftech MCW60
Laing 12v DD5 pump
BI Extreme 2x120 rad
8 case fans (which are quieter than my previous GPU fan on the 7900gt)
Well my last post may have been nullified. I seem to have another bad board......GRRRRRR. I keep getting BSOD's after a few hours and I changed my ram to the secondary slots on my P5N-E and i have not gotten any BSOD's since. I already recieved my RMA number from Newegg and I will probabally replace this board with a P35. I will report more later.
Mine E6420 does 3240Mhz at 1.32850V set on BIOS and it's stable(Orthos 2h, while running 3DMARK06 a lot of times,going trough the web,MSN all at the same time) but with this same voltage it doens't do 3400Mhz:( and also my Ninja is giving me worse temps then my 9500Led:()
consider yourself lucky PJD. None of the several E6420's I've tried could do that. Mine usually require about 1.45V BIOS (1.43V real).
BTW: When you mean stock voltage is 1.32V do you mean that the setting in the BIOS is 1.32V
or
that its 1.35V set in BIOS and that mulimeter or hardware monitor shows 1.32V?
Becareful, when you're not looking, I'm gonna come and gety'a E6420.. he he. At stock (all 1.35V) E6420 I've tried did, 2.64, 2.88 and 2.92Ghz
Mine won't do more then 3.2Ghz whithout giving him more then 1.35V:(I think I gave I'm 1,35xxV(I think) and even that way it wouldn't run 3DMARK06:(
mine does 2.8Ghz at 1,29375V on BIOS
The problem are the temps with the Zalman 53ºC running Orthos for 2h while doing a lot of loops in 3DMARK06
you still have headroom. 53C under load is no where near the danger zone.
And another thing that«s being worrie me:S: how canmy Ninja have worse performance then my 9500??
Edit:My E6420 doesn't run 3320Mhz with 1,375V:(
Not sure. It's my understanding the Ninja even outperforms the HSF i'm using (Infinity). Have you tried re-installing the heatsink? Maybe you used too much paste? Maybe the CPU needs to be lapped? I have lapped my CPU and load temps dropped approx 5C. Under full load(2 instances of prime) i hit 55C (room temp approx 80F). I'm sure once it cools down a bit here it will be considerably lower.
Some of the results you have seen here are truly 'cherry' cores. I consider 1ghz over stock a damn good overclock. Saying you can't hit 3375 with 1.375 is not a big deal. Like i said. I didn't get stable @ 3.2ghz until putting CPU voltage up to 1.42v. Time to give it more juice!
Some test over a 6420 in a unit made for a quadcore:
http://img375.imageshack.us/img375/9...6customhr4.jpg
http://img458.imageshack.us/img458/5...2customna3.jpg
I was limited by the gigabyte p35 ds3r Vcore and fsb, times are really bad because we don't fine tune the memory.
Nice clock there!
What is the vcore? or is 1.57 the vcore :O
I was actually testing the ram but it should still do for showing what my E6420 can do.
http://img375.imageshack.us/img375/9...tytest1aw2.png
I had a 24 1/2hr. shot but I lost it during a recent reinstall.:shakes:
What's the vcore??
@GripS:I installed my Zalman and now I need 1,335V to do 3.2Ghz but the temps are much lower then with the Ninja;) and the Ninja was good installed in fact it almost didn't fit and I cutted my finger on the damn Ninja trying to get it off:@
@DMH
Nice! What's your comparison for load temps between heatsinks?
@Mysterfix
That is damn impressive. Which batch did that gem come from?
edit: 8 hours prime is enough proof for me. Holy CRAP! (A shot showing vcore would be nice tho)
wow, that's amazing for a E6320/6420.
I have the vcore in my sig as 1.5v but it's actually 1.53v now. The chip it's self is stable at 1.5v butin order for the ram to be stable @ 1100+ I had to give the cpu a bump in juice. Very strange to me but it workes.
Minus 10ºC in iddle and in 9/10ºC in load:D I think Ninja stragulated(:shrug:) the air going through the NB and mosfet's also now I have 2 120mm going into the GPU,NB,SB and lower part of the dimms and one 92(or is it 80mm??I don't now:p) giving air into the mosfets on the top part of the motherboard and with the 92mm from the 9500 sending air to the rear mosfet's and 1 120mm extracting air,another 120mm from the PSU and one 92mm from TT at the top of the case:up:
And, what kind of typical ambient temps are we talking about with these crazy high overclocks on air?
For example my room is 30-35C. Idle temps always 40C+.
But, I dont think cooling has such a large impact on overclock. Its certainly a factor, and better than stock Intel heatsink will give you 100-200Mhz more... but, overall, you're limited by quality of chip.
First try E6420 and this CPU is good :)
I'm set vcore in bios 1.55V so probalby 1.52V in load ...
Mobo 965P-DS4 rev 1.0 and PI 16M stable at 3800MHz, boot @ 400 and clockgen to 475 x 8. Not bad for 1/2 hour testing :D
FPO of CPU : L709B010 - Malaysia

I got mine yesterday, primed 16 hours+ blend, 8x425=3.4ghz with vcore 1.4625 set @ bios. with intel stock cooler it gets most of the time 54-55 c degreece with short peaks to 57c @ coretemp, for 3.2 it needed 1,375 @ bios set, but for the 200mhz it needed a big jump:X 1.45 would crash after 1.5 hour, could it be NBv or FSBv, I had it on NB1.4v FSBv1.3v @ my p5k dlx, but 1.4625 did the job tho
#PFO:L651Bxxx
my 6420 sucks soooo bad.. 3Ghz @ 1.5v in bios.. 8x400 = no go - no matter what I do.. My E4300 does it alot better 3.4Ghz with 1.5v. Tuniq 120...
My god I miss my E6700ES, ran 3.8Ghz stable at 1.5v in bios..
Yup.... Looks like i'm in the same boat. I primed for 2.5 hours last night @ 3.4ghz with 1.45v. Unfortunately it was only for 2.5 hours. I'm gonna give it more juice tonight to see if i can get 8 hours prime stable.
Mine is a L650C by the way with a pack date of 5/11/07.

I get myself a better cooler soon Stock sucks hard!
66 DEGREES ALL THE WAY NOT EVEN 1 SEC 67. Piece a cake
IM Currently running 3,15 GHZ @ ortho stable for 2 hours tested not more yet. Great CPU! im very happy with it.. it was priced insanely cheap. Like memory was a 2 mohts ago..
YES! 3.4ghz stable with 1.5v. I would have like to have reached this point on lower voltages. But then again.... We are talking about 1.3ghz over stock here.:D
http://img2.freeimagehosting.net/upl...0fc8ecdcc8.jpg
got it with 1.5v. Under load it was reading 1.47-1.48. :)
ehhe n1 clock, yea it undervolts underload, here it showed 1.434
Just give it some juice.... if it ain't got HOT give it some more..). To much volts never would crash it.
I tried for 3.5 last night but could not reach it. I can boot into windows and run Super Pi with no problem. Prime fails almost instantly. The ambient temps are pretty high right now so i may need to hold off until it cools off a bit. I like to keep it under 60C under load which i am gettting very close to with 3.4ghz @ 1.5v. Looks like i didn't get a 'gem' but it seems to be better then average.:)
In that case.. 60 degrees,,,man that's L0W! ;). Seems nice :D.
Well mine got 66-68 (68 in hot room).
I think a CPU will crash (I mean by this wasted itselfs ;)) When running all the way at 90-95. That's what I think :). However even when I think I'm wrong, I never would keep it going "above 70´s.
I got this Result right now on the Stock Cooler .

Maximum core temperature is 68C with 82F room.
Wow, everyone's E6320 OC god-like, except mine! ;(
Did you get your higher than 3.0Ghz? Some reviewers on websites, and some users (like my unlucky E5420 #2) can't even reach 3.0Ghz.
I think anybody who can get 3.2Ghz with 1.45V should be satisfied. Its higher than fastest chip Intel ships, and a small fraction of the price. 10% more is ~3.55Ghz. But, its only 10% more. And we all know that even at 2.4 Ghz Core2Duo is already much faster than recommended for many games and programs.
i'm having same issue with the E6420 chip.
3.2ghz seems my limit. L702C560 stepping, on FuZion and g/byte's N680SLI-DQ6 board, F5b bios.
can boot and superpi at 500x6 (3ghz), but get it over 3.2ghz (500x7 or 415x8) and it dies. i guess 3.2 aint toooo bad tho.
I have a thread about this issue here:

The U120X is lapped, but IHS is not, so if I get the motivation to dismantle things again, I could probably gain a few c's and possibly some more FSB.

False... Any 'game' system with 8800 / 2900 series. Need maxed out CPU's talking about 3.5/4 or even more to feed...
The differences between 3 GHZ and 3.5 Ghz is freakin' Hugh! when talking about fast GPU's :slash:
In my case It's 1.86 Ghz to 3.15 with 1950 pro There is absolutely no difference in gaming @ 1.8 ghz or 3.2. The games run good or bad anyway MHZ would'nt change it to make it feel comfortable.
Games like Vegas wouldn't even do 20 fps @ 3.28 Ghz XD. (all high speed parts even 2GB)
8800/2900 dont need 3.5-4Ghz. Its usually limitation of game design. If CPU is busy doing software audio, software physics, and some stupid game AI that eats up millions of cycles but not all too bright, well that certainly interrupts with ability to properly feed GPU next batches.
Bottom line, you end up with FPS games like Far Cry, Doom3 etc, that scale OK, and get 100fps and taper of down as you approach gamer resolution like 1920x1200 4xAA where its just a question of enough GPU horsepower. In this case, any 2Ghz CPU + high end ASIC like X1900XTX is ok. On othe other hand RTS, with hundreds of units, or flight simulator, you never get 100fps, and its not that crucial to get very high frame rate, and game is very CPU demanding. Yeah, 4GHz C2D would be nice here, but thats only ~30% faster than 3Ghz. 10fps vs 13fps. Get my point?
Unlike GPU world where todays ASIC compared to 3 years ago is like 20x faster.

What kinda volts and cooling you need to reach that?
Curios where Lias found a quad 6600 for 230?
I've got my E6320 running 100% stable at 3.5GHz now (501 FSB), don't have much results or anything, but a couple of tests on 3.4GHz - didn't run any tests on my current clock yet:
http://www.xtremesystems.org/forums/...d.php?t=151380
I'm pretty happy with this clock. Take a budget chip and turn it into a killer chip ;)
Oh, well in the Netherlands here Processor prices are much lower than USA. And more sorts of products because of the strong euro. 236 Euro''s right now. For me it's cheap we get Euro;s as easy like Americans get the SAME amount in Dollars.. even less.
I bought E6320 Early for 140 euros. No money, absolutely cheap. But whatever I only buy from the best of the best Internet Stores.
About my Overclock results E6320 @ 3.2 Ghz on AIR. The mainboard quites the game :P. 460 FSB on 100 Euro worth mainboard P5N-E-SLI. I wouldn't spend 100 more for just 400 Mhz.
The chip is from malaysia and the chip code/date is the one which does 3.5 Ghz easily, from comparable. Thats's why i feel a bit pitty about it XD.
Nice overclocks :)!

waiting for my ZALMAN 9700 to arrive so i can try for 3.6+
I just got a 6320 and trying to push as high as possible. I think my RAM could do more than 500mhz because I've pass memtest at those speed.
The problem is, I can run Prime for few hours but will fail OCCT within minutes. Sometimes my pc will auto restart when running OCCT? Does motherboard limitation causes Prime to fail?
Is this Coretemp and TAT error? Isn't this supposed to be tjunction 100c? 1.2vcore (I got the worst batch L644G :( ) Ambient temps are +25-27c
http://i2.photobucket.com/albums/y45.../6420temps.jpg
Hi guys, i'm new to the forum, and my first post. so be gentle. :D
i thought i would share with you guys my 6320.
i am currently running Asus P5K-E/wifi, enermax 500w liberty, Zalman 9700LED, and G.Skill 2x 1gb ram.
at the moment the highest stable i can go 471mhz@1.56v in bios. limiting factor here is the v's i think. i can go higher mhz but it'll only be stable in occt for about 10-20 mins. how ever the funky thing is if i give it more juice, e.g. at 1.575v in bios, the motherboard :banana::banana::banana::banana:s it self, cmos bad checksum, and i can't boot at factory auto everything. only fix is to flash the bios again. :down: but then maybe it can be that the fsb is too high for this p5k-e. shrug.
but anyways here's my screen shots. idles around 30C, and full load goes to about 53C.
With stock cooling and stock volts my E6320 only does 3.0GHz. With 1.53v on a QuadGT using air cooling I've had it up to 3465MHz.
http://img155.imageshack.us/img155/2...0maxdd9fo8.jpg
That was a while ago though.
Dice ppl. 1Day achived this
No, I dont think so. I'm pretty sure all B2 stepping Conroe's have Tj 85C.
You seem to be idling in that pic, and assuming your room is pretty cool and you have good airflow, ~25C is normal. [EDIT: Just noticed that you said 27C ambient.. yeah thats strange}} If you're trying to see how high load temps go, click those two "start" buttons in Intel Thermal Analysis Tool, and just wait a few minutes. So far, it brings up higher temps than any other program that I've seen.
>1.5V. BIOS corruption at very high fsb. Motherboard shutting down at higher CPU voltage. Could be limitation of motherboard or CPU. ASUS P5E3 is putting up amazing overclocking numbers, hence the high price.
Any changes for the NB and SB voltages ?
Damn I hate how much voltage it takes to go up from 3.4Ghz
3.2 - default vcore (1.32v load)
3.4 - 1.4v (1.37v load)
3.6 - 1.52v (1.48v load)
3.8 - 1.6v (1.55v load)
my board maxes out at 1.6v at bios, and the vdrop + vdroop takes it down to 1.55v during load.
i have the right setup to reach 4Ghz: memo reaches 1000mhz+, chip fsb wall = ~530mhz, T.R.U.E 120 (3.6Ghz w/ 1.55v, max temps are 58º load) but the damn mobo has a HORRIBLE vdroop, and pencil mod didn't work.
