The Official E5200 Club

Testing indicates that anything over 3.3ghz requires more vcore, and the vcore required ramps up quick, till 3.8 requires 1.4+ in bios.
I tried every setting available, and regardless of them i get faults (either seg or rounding) in core1(#2, in human numbering). More vcore gets it working, but i don't like how high it has to go.

So now i'm sitting at 3300 or so (300ish x11) and seeing how low the vcore will go while maintaining stability. Right now i'm at 1.18 (bios) and looking good. Temps are down 6*c from their 3.4ghz 1.3vcore(bios), which is very nice indeed.
That is hopefully low enough for me to remove the xigmatek fan and install my s00per quiet chrome blue LED turbine fan of low noise. The xigmatek isn't bad at all, but in an effort to reduce temps while attempting to get 3.8ghz stable (1.4vcore, 65*c, still not stable) i taped over some gaps and such between the heatsink and the fan. That reduced temps 4*c, but increased noise decently.
It's also worth noting that i have the side of the case off, largely because i can't find the side panel. Gotta work on that.

 

[markp1989]

I got my new MB today, and i am testing it out currently at 4ghz 1.36Vcore

edit: I had to up the Vcore to 1.401 to get stable, prime takes temps upto 70C , and FAH takes them up to 65C(thats when the fan kicks in very loudly).

is 1.4Vcore ok for 24 hour use?

 

[blade321]

I've read on a couple of different posts that a few people run them at 1.4vcore and seem to all say you get about 12+ months out of them. Suppose it also depends on your temps and vdroop, from what ive read i wouldnt recomend 1.4 or higher for 24/7 use. Try notching vcore down 2 or 3 times and se what speeds you can get stable then, this will also bring that 70c down a little which is verging on hot.

 

[markp1989]

Im gona just run at stock speeds till i get a better fan for my heat sink, idealy i want to keep bellow 60 at load , 65C maximum, but il see how it goes, considering the price of the e5200 i can easily replace it if the worst happens, but id rather not have to do that.

 

[Bobnova]

Try 300x10, 1.19vcore, that's what i'm running at, only runs a couple degrees higher then all auto stock settings.

Link?

We have a guy on here that ran his 45mn C2D at ~1.5v for several months w/o issue.

For me the sweet spot was around 1.35v anyway.

And 70*C temps aren't gonna hurt anything. It's not like I run P95 small-fft 24/7.

 

[markp1989]

i have put mine back for the time being to 1.3v 3.7ghz some time over the weekend, i will read up online to see what all the options in my bios to, so hopefully i will be able to get to 4ghz without the noise.


The fan control on the motherboard sucks, i wana turn it of and use speed fan,

I just sold my e5200 but heres my 24/7 OC I ran.

This is my benchmark clock

Nice!

Any proof that the 4GHz clock was 24/7 stable? At what vcore, on which mobo, and what kind of cooling?

 

[Bobnova]

So with 1.425 bios volts (1.4000 idle cpuz, 1.408 load), 12.5x322, i got 4025ghz!
That's right, i got 4000mhz out of it, i'm very happy.
It even made it through wprime32 (2.0) in 19.999 seconds, which is another quest i've been on (<20s, stock is 33).
Sadly, the screenshot that i saved seems to have vanished (wasn't done saving?) when it crashed shortly afterwards.

12.5x320 is somewhat more stable, and turns in 20.000 wprime32.


That's way more voltage then i want to run on a daily basis, and not even close to 24/7 stable. I also found that the defective core in my e5200 processes things more slowly as well as not liking >3.3ghz. It's a bit over half a second slower in wprime then core0, every single run.
I'm going to see if i can find that screenshot. I have a very poorly laid out 1280x1024 of 4000, i was in a hurry to save it and didn't want to spend the time to arrange things compactly. The previous 4000 (at .025 less vcore) crashed when i got close to the save button


Oh yeah, and in other news 345fsb is all that it'll do, it just flat will not go higher, or at least not without more voltage then i'm willing to give it. It'll do 345 at 1.54pll 1.2vtt, but won't go higher at 1.6/1.3, so screw that.

Unfortunately that fsb limits my ram options to 1120ish or 1380ish, 1380 being faster then my ram is willing to do at 1.8v (no surprise there) and 1120 being lower then i really want it.
Still, the higher FSB has sped superPi-linux up by a bit, so i certainly can't complain.
I'll leave my comp folding while i go eat dinner and report back as to whether FAH runs any faster with the higher FSB-slower ram combo.

 

[markp1989]

I got 4ghz out of mine too was way happy, has been folding for a few days like this, with no problems the Vcore is abit higher then i like, but i have got the temps down to 65C at load, (re done the tim, as i put abit to much on last time)

http://valid.canardpc.com/show_oc.php?id=629153 (thats the load Vcore, cant remember what the idle 1 was)

Im getting 2 new fans through soon, so i can put push|pull on my heat sink, which should lower the temps abit more

I was at 3.75 stable with 1.3V so i have had to add quite abit of vcore for the extra 250mhz

 

[trev1976]

Hi everyone , im also a E5200 owner and i was struggling to work out how to OC my PC so i got in contact with jason in this thread and he really helped me out

Im now running stable at FSB 333 - Vcore 1.312 - Multi x11 = 3.66ghz

Nice, that's a nice OC, specially at 1.3vcore. Also, welcome to the club


I'm seeing how low i can take the voltage and remain at 2.5ghzish, right now i'm at 1.06(bios, probably 1.0-0.95 cpuz, haven't checked yet) with 337x7.5(2527mhz). Full load temps are 42*c


This seems to be stable:

337x7.5, .98vcore (cpuz), 1.56PLL, 1.18VTT/FSB termination, 1.18NB, ram at 1123-5-5-5-15-1.8v.
With the CPU fan at full blast it idles at 38*c and full loads (superPI) at 41*c. With Q-fan turned to Silent, it idles ~41*c and full loads at ~46*c.
Course now as i'm posting this it's failing prime95, despite having done 20 minutes of superpi quite happily. Bah.

EDIT:
With .99v cpuz it's nice and stable.
1.03vcore in bios i believe.

 

[filip04]

i just upgraded my computer yesterday... and i only spent about 25mins overclocking it today

i'm having problems with my memory above 300fsb, so i'll mess around with changing voltages later

anyways, without further adieu, first e5200 stock voltage/cooling overclock

 

[Bobnova]

Not sure i'd call 1.39vcore stock voltage

Nice result though.

 

[filip04]

you know, to be honest i didn't even check the stock voltage of this cpu.
however, in my self defense, all my voltages are set to "auto" in my bios:
CPU Vcore: 1.28750
CPU Termination 1.2000
CPU PLL 1.550
CPU Reference 0.805

and best of all, i have yet to research what any of those are... but i wonder why its running at 1.39V

 

[Boulard83]

Cause it need it to run @ 3.75ghz .................

Maybe a lil less if you manual it.

READ the OC sticky and learn how to OC. Youll have much more fun to do it.

 

[Bobnova]

Many mobos crank the voltages up when you OC with the volts set to Auto.
Set 'em to the VID and see how things go, that'll give you a much better idea of how it overclocks.

 

[trev1976]

Ok final update , been playing around with this for weeks now but its finally finished and finally installed in my AV rack



I upgraded my CPU Cooler to a Mini Ninja , ***** to fit but worth it for the extra cooling



Im now running stable at FSB 333 - Vcore 1.376 - Multi x12 = 3.99ghz

With CPU load temps of 70-72c



Im really happy with this CPU for £50 its a bargain , i was thinking about upgrading to a E8400 but now im almost OCed to 4ghz i dont think ill bother

My Windows scores have also improved again

Update !

Was running 3.0 but i jusr raised it a bit to 3.3 ( 300x11 ) and still very good temp with my Q9550 stock cooling as HSF for my E5200. Didnt tryed 3dmark06 to see if there is a lil jump from 3.0 to 3.3. Ill try it later and post.
