***The Official E4300 Overclocking Thread***

[markoboyo11]

I'm having similar problems - can't push my E4300 much over 2.3GHz. I'm sure I'm missing something obvious - and I'm not looking for an uber-overclock! - but I'm sure I should be able to get a little bit more than this...

I'm sure it's blindingly obvious, so go easy on me, but if anyone can think of something obvious, I'd be delighted. I was hoping to get the CPU running at somewhere between 2.5 and 2.8GHz - or was I being unrealistic?

Many thanks.

mate i am having the exact same problem will run fine up too 2.4ghz but wont go any further at all. tryed fiddeling bout with all voltages and ram settings but wont even boot windows above 2.4ghz.
Really stuck for ideas. got a artic cooling freezer pro and crosair 520w, along with p5n-e sli and crosair 6400 4-4-4-12 ram. any help would be much apreciated. cheers

Thanks. I changed to a 3:2 FSB : memory ratio, fiddled with a couple more voltage settings, and dialled in 1200 - and it booted, and is running fine (2.7GHz CPU, memory at 400 MHz, 5 - 5 - 5 -15 - 22 1T). (FWIW, this pushes both my CPU and memory scores in Vista to 5.9.)

I've tried 1230 - boots but crashes in Vista - and 1240 - which boots, but does not get as far as Vista. 1250 and the thing won't even switch on! So I've either reached the outer limits of this particular chip, or am stuck in another 'hole'. But, for the moment, I'm quite happy with a £80 chip that now runs at the sort of speed a £200 E6700 achieves at stock...

Thanks for your help!

Might be the memory - Try setting 2T command rate instead - mine doesn't like 1T at all.

Are you using one of the recipes from the P5N-E SLi thread in motherboards? Everyone else seems to be able to get 3.1-3.4GHz from an E4300, so there's really no good reason for you to be stuck at 2.4GHz as far as I can see

have you tried setting the pci-e to 105mhz? i had the same problem on my DS3.

worth a go.

Ive set my cpu to 1333 FSB and 1.375V but failed Orth test after 1h 37min any ideas plz

Increase the vcore? 1.375V seems too low @ 3Ghz for E4300.

 

[Nymins]

I thought 1.37v should do it for 3GHz. Im at 2.7GHz and im on stock voltage.

 

[MeatLoaf]

Well i should be getting an E4300 next week with my new rig so i will let you know how i get on. It will be used in a P5N-E SLI mobo

 

[steve258]

OK I can't get mine completely stable above 3.1Ghz so think I'm just gonna leave it at that

I've tried putting vcore of upto 1.62V and increasing NB voltage to max with a 80mm fan blowing the stock NB heatsink, also tried oc with only 2 sticks of RAM and running them sync with FSB but it just won't stop restarting itself The best I can manage is 3.2Ghz benchmark stable.

Only things I've yet to try is the vdroop mod and the 1066FSB mod as discussed over at extremesystem:

http://www.xtremesystems.org/forums/showthread.php?t=134550

Which apparently gives you more FSB headroom. Don't suppose anyone has tried this mod? If yes what did you use to paint the bridge that is readily available in the UK? The conductive pen cost £20+ from Ma***n and I'm not willing to spend that much just for 1 application.

Current settings:
Vcore - 1.4375 + 100mv
NB voltage - 1.53V
DRAM voltage - 2.35V
FSB: 1380Mhz
RAM: unlinked 1000Mhz 4-4-4-12-22 - I know it's better to run it sync but I've upped the voltage and it seems ok atm.
PCI-E: 105Mhz

Is there a need to temper with the advance mem timings? Every attempt to put manual figures in advance mem settings resulted in no post for me... I have only managed to manually set the tRC to 22.

 

[steve258]

I thought 1.37v should do it for 3GHz. Im at 2.7GHz and im on stock voltage.

maybe it's just my chip then, needing a lot more voltage to get 3Ghz upwards. Haven't actually tried orthos at 3Ghz though so don't know what vcore is needed.

 

[WJA96]

I thought 1.37v should do it for 3GHz. Im at 2.7GHz and im on stock voltage.

Are you on stock (1.325V) or [AUTO]?

[AUTO] could be 1.5V, as it just adjusts up and down as required.

 

[Nymins]

maybe it's just my chip then, needing a lot more voltage to get 3Ghz upwards. Haven't actually tried orthos at 3Ghz though so don't know what vcore is needed.

I would try and set the timings to 5-5-5-15 to see if you can get any higher. Those current timings seem very very tight for 1000mhz. And i would put the tRC timing to automatic for the mean time. Also the voltage seems kinda high on your ram. I would try 2.1v-2.2v and see if that works. Too high a voltage could cause it not to boot properly.

@WJA96 = My vcore is set to 1.325v, not at automatic since i thought it could affect overclocking.

ok am at 3Ghz and 1.375V, is that ok?

Also when I run Orth test it restarts after a while, why is that.

I ran it at 13.25 pm and when I cam back the PC looked rebooted. I checked Orth log and this was the last few lines:

Means it unstable, it will run forever if stable. If you're getting reboots its because your system is crashing.

anyone know how I can fix this then

Hi

Just got this lot last week

Asus P5B i965
Intel E4300 Core2Duo CPU - Stock cooler
Corsair TwinX 1GB DDR2 6400 (800mhz) CAS 5-5-5-15
500G WD SATA2 Hard drive

Anyway I was wondering what cpu temps u are getting with 2.7ghz at stock voltage with stock cooler?

Im getting 40ish at idle and 65ish at full load, is this too much?

 

[NightSt@lk3r]

anyone else round here get a dud chip?, mine will boot at 300x9 at 1.325v but any higher requires stupid voltage and anything over 335FSB wont boot.

Looks like it has only been running for no more than 10 mins. It most likely BSODed and restarted, it happened to mine at 3.15 (lasted for 3 hours) & 3.2Ghz (40 mins top).

Increase the vcore & NB voltage if necessary, and make sure your RAM is relaxed. If it still does it afterwards it's most probably at its limit.

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

With stock cooler and stock voltage im getting around 30-33 idle and up to about 60 when full load at 2.7Ghz. I could go a lot further but the temps would go too high.

65 is sort of pushing it with C2D, anything above 60 is a bit dangerous. But remember that a program like Orthos forces the cpu to 100% load, its very rare that an actual game will make your cpu do 100% load.
