***The Official E4300 Overclocking Thread***

c2d2.gif


10Hrs Fine...

1334QFSB (334x9) = 3.0GHz -, 67C max load (3-3-3-10 667DDR)
vCore 1.325v, nB 1.5v, vDimm 2.2v, +100mv used
Test bench: E4300, Stock Cooler, P5N-E, OCZ 2GB R2 XTC

What to test now?
 
So after spending half an hour reading through this thread iv still got no idea of an average overclock on the E4300 chips :D, im thinking of getting one to tide me over until quad core drops in price. So far it seem people are hittin around either 3ghz or 3.6ghz, whats goin on here?

Whats the rough average O/C reached with these chips ?

A database is needed... You can do it! :D
 
It's also worth noting not all E6600 will hit 3.6GHz!

I'm almost stable with 3.2GHz using this E4300 and it benches past an E6700 stock with ease. :)
 
It seems as with all C2D chips the E4300 tends to clock to between 3.0-3.6GHz. You'll be unlucky not to get over 3.0GHz and after that a few hundred MHz isn't going to make that much difference.
 
Just a quick heads up in case you didn't know, if you are getting lower temps in Speedfan than Coretemp, you need to download the BETA version.

http://www.almico.com/sfbetaprogram.php

You need to register first as the version isn't available as a mirror anywhere despite some sites stating their version is the BETA.

Speedfan will now show two temps, CORE0 & CORE1. :)

Intel Core 2 DUO Extreme Edition X6800 "LGA775 Conroe" 2.93GHz (1066FSB)

Dual Core Technology, 2.93GHz clock speed, 4MB L2 Cache.
Intel (£669.74) :eek:

A few hundred MHz may not make a big difference in performance but sure makes a difference to your pocket :)

Though it has a bigger cache, this equates to about a 10% performance increase so acheiving a clock speed close to 3.3GHz will give you X6800 performance..... Very Nice :)

Yes but all the overclocking in the world aint gunna get you the extra 2Mb of L2 is it?

Firstly the extra cache can be compensated for by extra MHz, not to the exact degree, but compensation is still achievable.

Secondly, I don't do any video editing (Premier, Avid, Photoshop, etc) and i'm not a programming developer (MySQL, Visaul C++, Delphi, etc), so unless you can see any major performance benefits in relation to the overhead i'd be paying for the extra cache, it's pretty obvious the extra 2MB would be useless to me.
 
Whats safe load temps on these?

Currently running mine at 2.5ghz. Max temp is 63c and that was what I thought to be high enough. This is orthos stable and undervolted at 1.225....

EDIT: on stock cooler using DS3 here :P

Anything over 70C is considered too high.

I've only had my setup for a couple of days, but i've been running Orthos on stock cooler with 1.4vcore (+100mv) in BIOS and ran 71C max load. As to why i'm back down to 1.325vcore (+100mv).

Max load 67C, which is on the brink of too high.

Just get a 6300.

The 4300 is only the choice for mobo's with limited FSB options

Have u tried adjusting the north bridge voltage & putting a fan over it?
Yup, one of the first things I did, however on startup, I can't see heat being an issue on the N/B. I simply can't get it to bootup.

Tried a suicide run of 1.5vcore and 1.8v on the N/B and it still wouldn't post with 400x6, mem on auto.

Then with a 6x multi, I tried 1520QFSB (380), posted, 1540QFSB (385) posted, 1560QFSB (390), posted but stalled on BIOS screen.

I'm definitely capped in some sort of FSB hole, as it seems most people are on other forums.

I was looking forward to running my CPU/RAM in sync at 400FSB/400DDR too. :(

If anyone needs a guideline, i've created a template from users on different forums and found the averages. I can vouch for the 3.0 and 3.1 vcore, but would need better cooling to try 3.2GHz atm.

3.0ghz - 1.3500 vcore
3.1ghz - 1.3625 vcore
3.2ghz - 1.4375 vcore
3.3ghz - 1.5000 vcore

I heard some talk of running non-round numbers (maybe try it linked/unlinked). Only other thing I can think of is that fsb mod posted in another thread.

Thanks, I tried 1601, 1604, 1680 QFSB's, but still no post. I then flashed back to 0202 BIOS and tried various settings, but again same deal. I still can't quite figure out whether it's the CPU or Mobo that's crappin out.

I'd love to see settings/environement/steppings, etc with of anyone who can get 400+ FSB with a E4300 on a P5N-E at the moment.

I'm not alone it seems...

"Just one thought. I own an E4300 with a Gigabyte 965P-DQ6 MB and DDR2 800 Memory and I was unable to get it to 3.6Ghz (9 X 400). The highest stable FSB speed I was able to reach was 360Mhz, and it wouldn't boot past 370Mhz. (Yes I know about FSB dead spots and tried increasing the FSB past it Very Happy )"

"If I lower the multiplier to 8 I'm able to boot up at FSB500 but the system only recognizes FSB390. It all seems to depend on which version of the E4300 you get because people with earlier versions of the E4300 don't seem to have the same problem. I suspect this FSB wall may be due to immature MB support for the E4300. I'm running the latest BIOS and still nothing. I hope you have better luck than I did but be aware that it may not be as easy as cranking the FSB up to 400."

I may just stick this E4300 on the 'bay and get a E6300 and see if I can reach a higher FSB. I'm guessing I will, so it must be the CPU crappin' out.

In retrospect it's clear now why the E4300 is cheaper than the E6300 albeit marginally.

Can you touch the Northbridge heatsink? I bet you can't - even just after startup.

Maybe your expectations are too high? After all, you have 3.3GHz from a CPU that's supposed to do 1.86GHz which is as near as darn it an 80% overclock. You appear to be complaining because you expected to be able to get a 100% overclock based on the 9x multiplier. As most E6600's won't do 3.6GHz, I think maybe you're not being realistic in your expectations?

I can touch the N/B at anytime for as long as i want (due to active cooling) other than when Orthos has been running for a good few minutes mate.

As for my expectations, I never expected 3.6GHz; the brunt of my posts have been regarding not being able to hit 400FSB with lower multipliers.

edit: I haven't got 3.3GHz quite yet either, i'm still only 100% sure 3GHz is stable. I'm testing 3.15GHz now.
