***The Official E4300 Overclocking Thread***

[WJA96]

65 is sort of pushing it with C2D, anything above 60 is a bit dangerous.

I don't know where you got that information from, but it's not correct. There is no such thing as a dangerously high temperature with a recent Intel CPU.

You physically cannot overheat a Prescott, Smithfield or Presler P4, nor any form of Core2Duo or Core2Quad (unless you use a blowtorch or something), they just shut down if you try hard enough.

Intel have years of experience of making CPUs that run in the high 70's and early 80's celcius, and if they hit roughly 85C, they shut down. If you have TM1 and/or TM2 enabled in the BIOS they even shut down cleanly.

I know a lot of OcUK users have been indoctrinated for years by AMD that anything over 55C is dangerous, but Intel chips have proper thermal management and they really cannot be damaged by over-heating.

 

[Nymins]

Well everywhere i read that has an overclocking guide says that you shouldn't really let the temperature go over 60c.

Thanks Steve,

However yesterday I increased voltage to 1.3850V and ran orth test successfully for 8H 55Min with CPU temp of 53C and system temp of 30C.

Not sure if i should run blend test now. The only thing am disapointed is my ram running at 667Mhz rather than the 800Mhz

3Ghz orthos stable at only 1.385V is very good. Mine fails orthos in 3 secs at the same voltage at 3Ghz. 53C under load is perfectly save.

Obviously you can go a lot higher so i wouldn't worry about the RAM just yet.

Yeah I could go higher but I don't want to push my luck and stress the CPU more than am stressing it

Would like the ram to go faster though

my CPU cooler is wicked though, its keeping my CPU cool

The max I can go on my Mobo is 6.7Ghz but that will blow my CPU

These cpu's seem to vary massively with voltage requirements. Mine does 3Ghz Orthos stable at 1.375v but to go to 3.2ghz and 3.4ghz it needs 1.4v. It used to need 1.475v for 3.4ghz but i have refined it down now. I did make some other refinements as well so they may have allowed me to reduce the Vcore.

Will I be able to get it to 3.4Ghz on a CPU fan instead of water cooling?

 

[pastymuncher]

If it's one of the high end ones such as the Tuniq Tower/Noctua/Scythe offerings i don't see why not. Just keep an eye on temps. My NB is also watercooled though.

I'm putting together my first C2D system for a mate next week, with an E4300.

We'd like to give it a moderate overclock, doesn't need to break 3Ghz or whatever, just looking for some quick settings that are likely to be stable as I don't have the time needed for lengthy stress testing.

It will be with:

GeIL 1GB (2x512MB) PC6400C4 800MHz Ultra Low Latency DDR2
Gigabyte DS3
X1950 Pro

I was thinking 400x7?

RAM/chip/mobo should do that easy enough on stock volts right?

Cheers

1.4V at 3.4Ghz How did you "refine" it down from 1.475V?

Seems like I need to set 1.475V in BIOS to make it orthos stable at 3Ghz. Mind you though the P5N-E has very bad vdroop problem so it's actually <1.39V when orthosing.

What's the vdroop like on DS3/P?

your lucky i need 1.475v to get mine stable at 2.8ghz.

E4300 has 9 multi so you only need 311FSB to bring it upto 2.8Ghz. Of course you can always lower the multi but depends on what mobo you have it doesn't always work that well.

Also to reach 400Mhz FSB you may need to overvolt the northbridge slightly.

Better to run 333x9 and set the RAM divider to 4:5 as that will give you 3GHz and the RAM should run fine at 416GHz. Don't put the volts on AUTO - set it to 1.35 and leave it. And pray that RAM boots OK as you'll need cheapo RAM to set the voltages with if it doesn't.

I'm not a big fan of that RAM to be honest. With an E4300, you could run the RAM 2:1 and get away with PC5300 RAM (667MHz) - how about this stuff?

If you can stretch to it at all, 2Gb is much better than 1Gb. I would even ditch the DS3 for an S3 to get 2Gb, as they perform identically.

 

[pastymuncher]

I can't say that i have actually checked. I will fire her up later and have a look and then post back. Probably be this evening. I am on my internet pc at the mo.

As for the voltage i just reduced it a little at a time and ran Orthos in between to make sure it was still stable. Eventually got down to 1.4v. Did the same with the MCH and FSB overvoltage too which is now down to +0.15 and 0.10 respectively. Thats down from both being set at +0.20 originally. I think i have got a really good cpu as the temps are very low as well. 45 degrees last week (when it was a lot hotter) on both cores while running Orthos.

Cheers but the stuff has already been bought, and the DS3 is b-grade anyhoo, so was only £58.

2GB wasn't within budget due to psu/tft/etc requirements, but he isn't a massive gamer, so a moderate oc and this setup will do him fine.

I'd rather not have any RAM booting issues, so do you reckon 310x9 with the 4:5 divider should be ok? RAM will be 12Mhz slower than rated, and oc will still be a comfortable 2.8Ghz.

Should the voltage always be set to 1.35?

Well I got the Asus Silent Knight Cooler

The problem with the RAM booting is that it's rated at 2.1V and the motherboard boots at 1.8V. It's much better than it was, initially there were masses of issues with GeIL RAM not booting in those boards, but it is generally OK if the BIOS has been updated. As your board is a refurb/return then it probably has an updated BIOS already.

There is no such thing as a comfortable 50% overclock, is there? If you run 313x9 then the RAM will be running bang on 400MHz, but as it's sold as overclocking RAM I think it'll be OK at 333MHz with a 5:4 divider.

The rated voltage for that CPU is 1.35V maximum, so yes - set it to 1.35V and it'll run fine at 333MHz. If you set it to [AUTO] you might be surprised to see it hitting 1.6V on the odd occasion.

I take it you've already been through the overclocking directions here? You won't need to whack up the CPU voltage as high as recommended there, it's really not required for a 333MHz overclock.

Enjoy.

Cheers, that link is VERY useful!

I'll give the 50% oc a go, if not, I guess he can make do with a 25% 2.25Ghz one.

Thanks

 

[beermonster]

after a bit of tweaking i can run orthos around 30 mins before the system restarts v core is 1.375 mem 2.1 temps around 62 full load, should i go any higher on the vcore , stock cooling btw.
mem is geil pc2 6400

 

[Nymins]

Quite happy so far with the E4300. Basically 2.8GHz at stock voltage and cooling:

I know its not the longest Orthos but its extremely stable overall and hasn't crashed yet.

 

[toM123]

Nymins you should use coretemp 0.95. 0.94 reads the e4300s temp 15C too low.

Try Intel TAT as well it should match what coretemp 0.95 reports.
