How does your Core 2 Duo E4300 Overclock?

[jazztrumpet216]

I'm interested in finding out how these chips OC ON Average so please vote only once for each C2D E4300 you have OC'd. Please vote for the max stable clock (were talking 24hr. Orthos stable).

(Poll as requested by Able72)

PC#2 in my sig. P5B-E @350FSB = 3.15GHz.

It is 100% Orthos stable at 3.2GHz, but I always prefer to back down a hair from my fastest Orthos Stable config for 24/7 operation...

My e4300 (PC#2) runs faster than my e6320 (PC#3) on the same board :eek:

:cool:

[Able72]

nice. . . hope I can look forward to similar results with my new E4300 C2D :D

Mine has been 100% stable for 2 months now, I'd like to take the chip further but it seams my motherboard is limiting my oc.... can't get past my dead spot at 363x9, I may have to take a huge leap to like 400 to pass this wall.

What are your voltages at this clock?

[GTengineer]

3.4GHz, anything higher seems nearly impossible

[Alexhk]

Had to back off to 360 x 9 = 3.24Ghz after I discovered the computer was randomly rebooting about once every ten days (running Seti) @ 362 x 9.

Yeah the strap changes at 401 (loosens northbridge timings allowing higher frequencies) on the DS3 so give it a shot but you may or may not have any luck with it. Many e4300+DS3 users can't get past the FSB wall your experiencing, including myself. Eventually I'll get around to trying the BSEL mod though...

Not 100% sure off the top of my head but it's like 1.42v (slightly untuned.. can probably go down 1 or 2 steps just havn't gotten around to doin it) I tried 365 and pumped it up to 1.52v to no avail... think this weekend I may try hitting 401 and see if it busts the wall.. my temps at 100% load is at 50* idle is like 22* which to me seems odd cause thats almost a 30* jump

[Able72]

Excellent, thats not bad at all. Early poll results seem to show most people getting between 3.0 and 3.2GHz. Not bad, considering the E4300 stock is 1.8GHz. Well, I'm due to build my new system tomorrow. After my 24 hour burn in we shall see what it will do :D

We need more people with the E4300 to vote for their OC :D Lets get a really good sample size so we can determine with some degree of reliability how well these chips OC.

[muddocktor]

How about an E4400? If you want, when I get in from the drilling rig in 1 1/2 weeks I can throw it on my DS3 machine and see what it can do. I know it's not an E4300 but it is it's bigger brother. :D And a true Allendale, like the E4300.

EDIT: I won't go for a 24 hr Orthos run though as that robs valuable crunching time. I will give it a 6 hour Orthos run though.

[Captain Hilts]

I've got my E4300 at 3GHz right now, this is at stock volts. To be honest I haven't run Orthos for 24 hours yet but I did run it for about 14 before stopping it and haven't had any stability issues in general. I also put together a similar system for a friend and he's at 3GHz as well.

I had mine at 3.3GHz with 1.4v but TAT reports temps close to 80c full load, even though it was stable, so I had to back off. Speedfan core temps are much lower so I'm not sure what to believe but I'm keeping it at 3GHz to be safe. I don't know why it would be running so hot as I have pretty good airflow and the Freezer Pro, while not the best HSF out there, is decent and the mounting seems pretty tight.

[akkuma]

use speedfan... I used to use TAT but I read a write up somewhere that said speedfan reads correctly on e4300's and TAT doesn't... I checked my idle against my bios reading... and speedfan is 1* off... TAT was 20* off.
And a quick update... I got 370x9 (3.33) to run stable (got up to 374x9 but not stable) however nothing above that could boot... I tried every step from 370 to 430 at 1.6v (I didn't go past 1.6v cause theres no way even if it did boot that I'd run it at that).
So right now I'm at 370x9 1.55v and 51* 100% load!

Do you have a link to this write-up? Speedfan is much closer to my bios idle temps too but I don't think I have core temps in my bios to check against TAT.

[akkuma]

I'll see if I can find it. (read it 4 months ago when I started OC'ing my then new rig)
On speedfan the bottom 2 numbers (can't remember what they say) are the core temps.

[akkuma]

sooo from some of my quick searching I've read that tat and coretemp are wrong because they assume a Tjunc as 100*C rather than the 85*C that it should read. Assuming that, TAT and Coretemp are off by 15*

[Captain Hilts]

That seems to be the problem, there doesn't seem to be a definitive answer about whether the E4300s have a tjunction of 85 or 100. I'm worried about guessing wrong that it's 85.

Anyway I didn't mean to hijack the thread, I suppose we should continue this discussion elsewhere if need be. :)

[redrumy3]

426x8 1.35 so far so good :) but i leave it @ 400 x 8 stock volts 24/7 i can boot 400 x 9 @ 1.5 just havent tried playing with it to get stable. plus i rather have watercooling or something for that kind of volts

[IamPWNT]

I am running cool and stable at 3.0Ghz, I did get it to boot at 3.25Ghz but backed off. I am sure with some more tweaking I can get more out of it. But I am very happy with the performance of the chip as it stands.

[akkuma]

sob red did you have to do any strap mods to get yours to boot that high? I tried everything from 375 to 430 I believe and nothing worked at all... what bios version are you using? I'm using f10 cause I got it to boot at 370~374 but thats as high as I could go... f11's highest was 364 and f9's was 362... maybe I just got a bad board :(

nope didnt do that strap mod, i use F10 Bios Rev 1.0 Ds3 :) i guess i got lucky

[xtreme_ego]

3 ghz stock voltage

yea i picked one up for the mother works nicely

[pillfred]

I got mine running 400x8 but my temps were too high i think my volts were 1.33?. When i get better cooling i'll give it a go higher again. Right now i have it at 2.7. Which is what i was hoping for but of course i want to see how far i can push it. :cool: But then again who here doesn't?

[DevilChildrens]

Man, i manage to push my E6600 from 2.4 to 3.6 with 1.5 v and i run prime 95 the whole night and its stable... i just wanted to know if i can push my voltage further, my temp are great they dont pass the 50 celsius on full load running hot potato 2 time to be at 100 % cpu usage on both core.(dont look at the cpu-z voltage, its bogus, no way i could get this to 3.6 with only 1.21 volt)

[akkuma]

be carefull... speed fan may be reading low on your board (you could actually be at 65*)... check your idle temp vs your ambient temp. What does tat or coretemp say your temps are? those programs should be correct on a b2 revision (who knows?).
regardless I wouldn't suggest going much past 1.5v .... i've pushed mine as far as 1.6v cause I was ****ed at my board for not allowing me to clock higher (damn wall). Think I'm currently at 1.55 (may be 1.45 I'll have to check again, been a while since I've been on my comp at home).
