C1E & EIST disabled
Stable:
1) 3.2GHz (8x400MHz) undervolted from 1.325v to 1.28125
Mainboard voltages are stock. Not set to auto, because the BIOS is automatically increasing them, but set to manual.

2) 3.6GHz (8x450) @1.425v

e6320 L707A573 7x458 3.2Ghz 1.38v 35'C idle 47'C gaming with arctic freezer 7 pro.

How about the (Northbridge) chipset? Seems like the chipset temps could be an issue even more than the CPU, I've just got a stock cooler so I'm only running mine at 333Mhz FSB for now (same CPU & MB as you). I was looking at either the CPU cooler you got, or the Coolermaster Hyper TX 775. Did you try OC'ing with the stock cooler before u put the Freezer on it?

I guess you need fast memory with the e6320, the multi is so low I didn't think it through enough or I might have rather gone with the 4300...

My new E6420 L702C554 aircooled by Sharkoon Copper Twister (3500rpm on max.)

It can boot to windows @ 3600mhz with 1.44Vcore on bios ( DFI P965-S unmodded)

I tried to overclock it more and here is print screen @ 3837mhz with 1.56Vcore



and I tried more

3920mhz with 1.60 Vcore



forgot to validate it

Bought this from Newegg and recieved it this last week. Been messing with it for a bit to see what I could get out of it. Doesn't help that the current ambient is around 100F as I haven't put in the AC yet. Does 3.1 on default volts. This required 1.45v. Why CPUZ reads it incorrectly I dont know.

C2D 6420 - L648G416 Pack Date 3/28/07

Running on a P5N32-E SLI Plus Mobo
Foxconn 8800 GTS 640MB
1GB DDR2 800 Kingston HyperX (Soon to be 2GB)
EDIT: On air with a Tuniq Tower 120

I could run memtest86 up to 3.9Ghz with no errors, although nothing over 3.6 was stable in XP. I would get random reboots. Makes me almost think my PSU is not up to the task. It's an older Antec 550W that needed the 20 to 24 pin converter and the 4 to 8. That'll be the next thing replaced to see if it allows anything higher then 3.6
stable in windows.

some update on my E6420@3.64ghz

Failed to run Pi 8 million due to the heat

[alpha0ne]

Thats a great core you have there memory


I think I may buy one of these 6420's as Penryn wont arrive till next year IMHO

[jinsean]

I was freaking out a little bit at some of the earlier posts, but glad to see the e6420s pushing past 3.5ghz...

Mine is arriving on Friday, but won't really have my new system set up for another 2 weeks or so. I'm doing a massive water cooling project for my e6420

I just got a L707 6420 from newegg, just waiting on ram. this should be fun

[Shampoo]

Hey guys, I picked up an E6420 L707 A5xx something, and I'm only able to hit 3.4 with 1.51v on my P5N-E SLI.
Here are some screen shots. Kinda sucks considering you guys are hitting 3.6 and more.
I'm still happy though.

I'm coming from an E6400 that did 3.4 with 1.46v on the cores, so I'm satisfied.

Still playing with this thing so we'll see what happens.

I'm running all this with a Thermalright ultra-120 Extreme with a Vantec Stealth on it in an Antec P182 case OCZ GameXStream 700w, eVGA 8800GTS 640MB, OCZ Titanium EPP 2GB, X-Fi XtremeMusic.

I had really hoped for 3.6GHz, but one can only dream sometimes I guess.

Cheers,
Mike

Hi, here is my overclock for my vcore hungry cpu.

[Reverendrun]

I think this is going to be my 24/7 clock. I still haven't tried to find the max on this e6420 yet (L651B from tankguyz)--but it seems kind of voltage hungry. I was hoping to hit 400x8 on stock voltages--but that did not happen. Everything I read said L651B was a good stepping--but the one I received seems to need a lot of vcore compared to many other e6420's I see in this thread.



375x8 only needed stock volts and my RAM only needed 2.0v.

400x8 required:
vcore bump of +.100v
nb +.200v
vtt +.100v
RAM 2.2v

I've had the board up to a 475mhz FSB at stock volts--so I know it's not the board holding me back. I think I'll be able to do 425x8--but I'm sure it will require another +.100 bump on the cpu, and in the summer months I think my temps will get a little out of control with 1.5v on the cpu and 2.2v on the RAM.

[trajik78]

yup. im at 400FSB 3.2gHz 1.425vCORE on my E6420. happy there. dont feel like roasting my cpu.

[GripS]

got my 6420 yesterday. I think it was an L650C (will verify when i get home) with a pack date of 5/11/07. Just put the setup together last night and will post results when i have time to play with it this evening.

[critofur]

i have a E6320 setting on the desk! lol (got it for free, lololol!)
still looking for a MoBo for it.. but can't decide which!

Gigabyte 965P-DS3

How do you get a relatively new model CPU for free?

[OV3RCLOCK3R]

My 6420's arriving tomorrow. Will post results

[flutie98]

hmm this chip aint bad, L707A252

425x8 @ 1.42v

havnt really pushed it yet, just trying to find a nice 24/7 clock first

[flutie98]

hmm guess this chip is turning out quite nicely, and this ram is really nice specially for $64

8x450 @ 1.5v

[xenoasd]

nice oc.. mines did 1.55 @ 3.6 before.. wasnt orthos stable.. had to drop it too 3.4 ghz >.> gonna get a quad soon

[GripS]

Not much yet. It is a L650C E6420 currently running 2.9ghz on stock voltage. Gonna run orthos overnight at 3.0. So far i'm very pleased with the boost in speed over my opteron 170.

[All_Star]

I can get a L709 A177.

Should I go for it?

[steelballzz]

hey guys

i got myself a 6320

borrowed a p5b deluxe and start pushing it.....









only had time to run these bnchmarks.......i had to return the board.....


right now i have it mounted on my Abit Quad GT

487 fsb..(max stable for this board)..3400 for 24-7 use...folding and playing C&C3 with 1,41 vcore


i am trying (hard)to find a board that gives me at least 530 fsb so i can push it a litle further

later i will post a pic of the cpu showing the batch code

regards

I am just shy of 3.7 with mine but am changing to the Fuzion, might be able to break 3.7 with it. Until then here is 3680. I can run 3.6 @ 1.44v tho. Primes all night long
