The Official E4300 Overclocking Thread

bluetech · 13 Apr 2007 at 21:03

Jast wanted to say I have solved the above problem by opening another thread. Other people have had this issue. The easy way to fix is to up PCI-E freq to 110MHz, mine is @ 105MHz and has resolved the X1 PCI-E issue (now stable @ 16x)

Hey guys sorry to ask i just thought i should,

im running the 4300 duo (obviously)
and artic freezer 7 for cooling
giel 6400 2gig ram
Asus p5n-e sli mobo

and im running at 3008.1 Mhz
Voltage 1.296v
rated fsb of 1337 Mhz
bus speed 334.2 mhz

I was just wondering what i should be aiming for overclocking wise, also i just noticed my ram says its running at 401 mhz, is that right?

Sorry im a bit of a noob.

Without actually overclocking one myself (yet), just from reading i'd say that what you're up to now is pretty good and widely expected from the E4300. It seems many reach 3.2Ghz (and some beyond) by notching up the voltage a little, but hey i'm a little out of touch as it is... i'll be in your position this time next week you just watch

Whats the highest reasonable temp on stock cooling?

I've had 2.9 on stock with boosted voltage on a Gigabyte S3, and 2.7 on stock volts and cooling on an Asrock 4Core VSTA.

60 degrees under load for the 2.9, 50 for the 2.7.

OK have my @ 3.2Ghz but I need to put a lot of voltage through it, here are my current settings jus to make sure I am not missing anything:

Vcore: 1.475v +100mv
Chipset voltage: 1.39v
Mem voltage: 2.25v
Every CPU options disabled.
Every onboard features disabled apart from LAN, both IDE ports and SATA 1,2 which I am using.

It's not stable at 3.25Ghz and it refuse to boot at anything over 1450 (363Mhz) FSB.

Has anyone managed to reduce the multiplier on P5N-E? I set mine to 8 but it sets itself back to 9 everytime after reboot?

Also has anyone done the pencil mod on P5N-E as suggested by vr-zone? How effective is it in reducing vdroop?

Apologies if these questions have been asked earlier.

I am running mine at 3.4ghz with the following settings:-

Vcore was 1.475v but have now settled at 1.4v.
378x9=3.402ghz.
Vdimm 2.1v.
Fsb overvoltage +0.20.
MCH overvoltage +0.20.

For 3.2ghz i can use the following:-
Vcore 1.4v.
356x9=3.204ghz.
Vdimm 2.1v.
Fsb overvoltage +0.15
MCH overvoltage +0.10.

For 3ghz i can use the following:-

Vcore 1.375v.
334x9=3ghz.
Memory on a 2.5x multiplier @417mhz.
Vdimm 2.1v.
Fsb overvoltage +0.15.
MCH overvoltage +0.10.

I am on water and specs are in my siggy. Probably only any use to the guys with DS3/DS3P's but i hope it can help someone. It does boot into windows at 3.6ghz but i have'nt ran Orthos to check for stability yet. Currently happy @3.4ghz.

Abz · 1 May 2007 at 12:11

I got a IN9 32X Max 680I Mobo and am currently as 2.36Ghz,

Anyone has this board and what the max they have been to?

btw mobo is wicked for OCin.

Try upping your northbridge voltage. WJA96 recommends 1.563 for these boards.

Only if he has good cooling on the Northbridge heatsink.

You didn't mention that to me at the time........

Been running at 1.563 with stock heatsink. What should mine be set at then?

You may have hit the limit. It's a fairly hefty overclock (1.4GHz is nearing double the native CPU speed) or you may have hit an FSB hole. Try something like 1508 or 1512 which seems a big jump, but it should get you over the hole if there is one. clv101 has his E4300 running at 3.4GHz so it is feasible to run them that hard.

You're also a bit concerned about the voltage, but actually it's OK as long as you have the cooling to handle it. A lot of E4300's need 1.6V to do what yours is doing at 1.575V, so I think you have a good CPU.

If you're running unlinked, and your RAM is good for it, try running linked as that is a fraction easier on the Northbridge than running unlinked. As Zytok noted in his post, it's pretty normal to run 1.593V, but the Northbridge can get pretty toasty on that setting, so you may want to be a bit careful.

It's broken on 0505 - you either need to go backwards to 0401 or hopefully it's fixed again in 0602. Reducing the multiplier on E4300's seems pretty counter-productive on most boards anyway, so I'm not sure you're missing out on much

Lots of people have done it. Check out the Official P5N-E SLi thread in Motherboards for piccies and peoples opinions on the best pencils to use etc.

Well, you obviously have good cooling then if it's stable.

Definitely the tidiest build I've ever done. Looking in at the mobo, I can only really see one cable, the one powering my GTS. Everything else is routed round or under the mobo. I have a 12cm fan mounted behind my hard drives sucking in, a Coolermaster TX pushing air towards the back and another 12cm fan at the back blowing the air out the case. The pc is completely stable at the settings you recommended to me a few weeks ago and is frequently left on overnight. I haven't really experimented with reducing any of your suggestions as I was happy with how it was running. Might have a go at reducing them a little just to see as I've just received some Hyper 12cm fans that are supposed to push more air than my Antec Trio's despite being quieter.

for some reason when I notch it to over 2.5Ghz it seems to freeze and not boot in to windows! :confused:

Edit : am using windows Vista 64bit

You are highly likely to get "FSB Holes" where you think you've pushed it too far but pushing a bit further or adjusting your voltages will suddenly get it booting again.

What sort of temps are you getting under full load ?

CPU seems to crash after I OC over 2.4Ghz and about 1.4v.

Does that mean 2.4Ghz is its limit?

Will try jumping the fsb to 1512+ as suggested tonight (don't think my E4300 will have any of it though). I know there is a fsb hole from 1200-1300 on my board - setting the fsb straight from 1200 to 1333 and it posted just fine. It actually posted at 1466FSB since last time I posted here.

1.575V at 3.2Ghz proved to be unstable - got the "Machine Check Exception" BSOD after 20mins of Orthos. Last time I ran Orthos at 3.2Ghz was with 1.5875V and that ran fine for the brief 40 mins of Orthos session.

I backed it down to 3.1Ghz @ 1.4375+100mv now with the RAM running in SYNC mode and NB voltage at 1.57V as suggested and it was Orthos stable for 9 hours+

Finally a stable OC which I can work my way from. Tried 3.15Ghz with the same vcore and Orthos "STOPPED" just under 20mins. Increased vcore to 1.55V only made it reset after a while of orthosing - most likely heat related as I don't have active cooling over NB, or maybe due to 4 sticks of RAM.

Thanks, at the moment I don't think reducing the multi will help improving the overheating NB situation so I'll just leave it at 9. Pencil mod seems easy enough to do but I am not planning to apply the mod as I am quite happy to just increase the vcore to compensate - high idle temp doesn't really bother me tbh.

Tonight I will try orthos again at 3.15Ghz 1.55V with a 8cm fan blowing over NB and see if it stops the machine resetting. If it works then I may get an Antec Spotcool (is there a non-led version of this?).

Thanks again for your help WJA96, this thread worths nothing without your inputs, will post back when I get some results.

About 5-6 weeks ago i was getting 33 degrees on both cores while running Orthos but it has got a lot warmer up here now and Orthos bumps it up to the high 30's, low 40's. Never gone over 44 degrees though.

I have my triple rad set up in a rad box on a windowsill.

Here's a piccy from 5-6 weeks ago:- http://img86.imageshack.us/img86/1441/430034ghz7hoursorthosnz4.png[/IMG]]

Thats a good overclock! The temps are really low too!
