E4300 @ 3.33Ghz

Speedfan 34-35 idle
Orthos 67 load
AC7 Pro
FPO/Batch # L649H046 (Pack Date 05/01/07)

Don't know if you need any more information then that, but if so just let me know.

Quick question, I'm trying to make it to 3.4Ghz but I'm having no luck at all. I've tried upping the voltage to around 1.48125 and even 1.493 or something around there at 9x378 with no luck. I tried even at 8x425 and my computer then won't boot at all. But using 9x378 I fail orthos around 11 minutes. Do you all think I've just hit the highest I can get with this chip? Would adding more volts to my northbridge or FSB do much? I'm already at high temps with only an arctic cooler pro 7 but I don't plan on keeping this chip for more then a year or two. Thanks.

Drop back to 1:1 memory divider with 2.0Vdimm and 5-5-5-15-2T timing.

I've already tried running at 1:1 with 5-5-5-15, it helped but didn't quite make it. With a tjunction of 100C how high can you run these chips?

hey just wanna add my actual setup for those who are still "afraid" of oc.
My e4300 is running @ 2.7 ghz (9x300mhz), voltage is stock with the stock intel heatsink. 30C idle and 47C load.
Im using intel's EIST so most of the time in windows the cpu is running at 6x300mhz.

I wouldn't push it past 75C under Orthos. The chip can get flakey north of 70C. Again, actual performance may vary from chip to chip.

Try 333MHz and see if PC will POST. That should be within the comfort zone of the stock CPU cooler. You many want to bump Vcore up to 1.35.

added johnny for e4500

@newschool I will put in your oc if you can provide the info listed on the OP, thanks

@johnny, nice chip you got there as you can see mine takes 1.5V to reach 3.4ghz and I ran into temp problems in my centurion case at 3.5ghz(had to bump vcore to 1.55V). My next goal is to see how low of volts it can run at stock so I can do some research for a htpc upgrade(our current is a 2.4ghz p4).

zach,

Thanks for keeping this up-to-date. A suggestion: Consider grouping similiar Processors with a Bold Heading, if you a some extra time.

Thanks again,
Hermit

3.6GHz with a sizzling 1.505Vcore and 600MHz RAM speed. 14min 1 sec 32M Super Pi. Still need 66F room to pass S&M 100% heat mode. I'll try to shoot for 3.69GHz/1.545Vcore around Dec with sub 55F ambient.

[zach0624]

updated for serpent. Rearranged the oc's into e2xxx and e4xxx following hermit's advice(it was way too jumbled)

 

[newschool]

I have a e4300 so 6 to 9 multiplier. Is there a big difference between 7x400 & 9x311 knowing both are at 2.8ghz?
I know there is a performance improvment with a faster FSB but is it worth it ? I heard that the NB and other mb components runs hotter with higher fsb.

Plus my ram is at 800mhz so having the FSB at 400mhz would make it synchronus = an other small performance boost.

Basically im wondering about the stability of a system with higher fsb and lower multiplier.

 

[hokiealumnus]

You'll see a boost in synthetic benchmarks, but it won't be even close to noticeable in the real world. There are several draw-backs to dropping your multi:

1. E4xxx chips just plain don't seem to like it or get any improvement from it.
2. You cannot run C1E & EIST on anything other than the default multi. They help keep your processor cool by dropping the multi & voltage while idle.
3. Your NB will require extra voltage and run hotter, again for little improvement in the real world.
4. Your RAM will probably require more voltage to run even at its specified timings to compensate for the higher FSB.

Just some stuff to think about.

 

[hokiealumnus]

@ OP: Please update...It's not much, but I'll take what I can get. This is the highest I could squeeze out of 1.525Vcore (1.50 after under-volt & 1.49Vdroop)

Hokiealumnus
E4400 @ 3.42ghz (L2)
1.525V
Abit IP35-E
OCZ Plat. Rev.2 1Gx2 @ DDR2-820 (342FSB @ 1:1.2 ratio), 4-4-4-15-2T @ 2.05Vdimm
Thermaltake Big Typhoon

Screenshot

I'm reaching the limit. I got 3.45 seemingly stable @ 1.545 but temps got to 77c pretty quickly so I couldn't torture it any more. If I can get some extra cash to get a higher CFM fan for my BT, we'll see if I can push it a bit more. I have no doubt I could get 3.5 with water...but there isn't any $ for that!

Like the other folks have said...thanks for the thread; it made overclocking this thing quite a challenge...and made me push it further than I would have for the competition of it.

 

[SerpentRoyal]

A faster fan will drop your Core temp by 2 to 3C max. I also enjoy toying around with my E4300. Still blazing hot today (+90F) but I'm hoping to see sub 55F in December. I feel the need to break 3.7GHz with 1.545Vcore.

I agree with hokie on this one, my e4500 won't run above 2ghz with a 10x multi and disabling speedstep is really a bummer. What you pretty much have to remember with c2ds is that clockspeed is king and stuff like cache and fsb are secondary(why the e2xxx and e4xxx are such great deals) and also a higher fsb has little effect on real world performance period (if you read the UT3 cpu preview you will notice almost no diff in fps with a bump in fsb from 800-1333, something like 1%?, and it is a pretty cpu intensive game).

 

[zach0624]

updated for hokie.

Thanks everyone for your input and for suppling complete information and properly formatted(people are almost getting too good...)

 

[24601]

damnit, I R BEATEN!~

Gonna try some more hokier methods of getting higher clock (air conditioning)

 

[zach0624]

communism, what are your temps? I remember you had a pretty good oc but weird temps(97C+, which is past what coretemp says mine is at at 3.5ghz (84C) before I shutdown), what's your current oc and have you gotten temps down?

Rbk123
E2140 @3.2Ghz

Math just doesn't add up on this one...

 

[harpoon84]

Just an update on my earlier entry... (I think it was 3.15GHz stock volts or something)

I've since tested my L2 stepping E4400 @ 3.3GHz (330 x 10) @ 1.4V, stable on the stock HSF.

Don't think I can push it much further without getting a new HSF.

 

[hokiealumnus]

@ OP - Stick a fork in me...I'm done. Please update for (probably) the last time. This is the highest Vcore I can bring myself to run without having income to throw away on a new CPU. Without further adieu:

Hokiealumnus
E4400 @ 3.45ghz (L2)
1.565V
Abit IP35-E
OCZ Plat. Rev.2 1Gx2 @ DDR2-828 (345FSB @ 1:1.2 ratio), 4-4-4-15-2T @ 2.05Vdimm
Thermaltake Big Typhoon

(Screenshot)

Just couldn't eek 3.5GHz (or 3.47 for that matter) out of it at that voltage . Prime crashed it. Oh well, you win some, you lose some.

 

[24601]

1.605v
3.6ghz
coretemp 83c @ 73f ambient temp (too lazy to convert )
i gave up on the small torture test and did the large torture test instead, the small one went up to 9xc and crashed often

btw i'm totally going to go higher than 3.6ghz soon!



UPDATE:
ok, i found out my tjunction is 100c from coretemp, also, new top results!
1.645v
3.7ghz
coretemp 89c @ 73f ambient temp

http://valid.x86-secret.com/show_oc.php?id=261238

I'M STILL AIMING HIGHER , my MB still lets me put the voltage higher so i will try in 30f- temps soon!
Winter in South Dakota ftw

yeah that is weird, will have to find that post and find out what the real numbers are.

I'm not sure if you really care or not judging from your posts, but you take the rather serious risk of totally frying your CPU. Temperatures are one thing that can do it (and 89c is very close to if not already frying your chip). Voltage is another. Even people with phase change cooling that keep their temps well under 30c under full load fry chips with too much voltage. You probably already know this and what not...just wanted to say it in case you didn't.

But if you did and want to keep going...by all means, show us what you've got! Please post a SS that includes SuperPi. Definitely curious to see your times!

Super Pi will not be very impressive due to the low FSB and RAM speed. In general, if the rig can pass 32M Super Pi, then it's within 30MHz of Orthos Large stability. My OS will lockup/reboot/BSOD if my core temp is north of 80C.

My rig will reboot if the temp is over 80C also, my guess is that he probably is using a different version of coretemp or some other temp utility because 84C is the highest I have ever seen before a reboot. On the super pi times what have people been getting with these chips, mine gets into the low 17s or upper 16s at 3.3ghz.
