I want to OC my Intel E5200 from 2.5Ghz to 3Ghz with a FSB of 240 and 12.5 multiplier on Abit IP35P motherboard.
Which voltage do you recommend me ?
Is it enough to keep the standard 1.125V or is necessary to increase it?
I use the BOX cooler.In full load without OC the temperature of Core #0 rises up to 60 degrees Celsius.Core #1 is runs 3-4 degrees cooler.

If it gets up to 60c on stock settings, I'd leave it alone until you get an aftermarket cooler. Every system is different, so the only way to see what voltage you need is to test it out yourself.

CPUID shows CPUTIN lower than Cores temperature.
CPUTIN shown by CPUID is identical with the temperature shown by Abit EQ.

Mine e5200 only needed voltage increase when I reached fsb 266, before that was stable without inceasing vcore. Anyway, do your oc and run some demanding app to check stability, i personally use 3dmark06 - if it crashes then i slightly increase voltage and try again. As for temp: mine after oc hardly ever reaches 60 celsius on box cooler

3dmark06 might not be the ideal benchmark, considering it can be more gpu intensive at certain points

With stock cooling, I would not exceed 1.25v nor 4GHz cpu clocks(highly unlikley on an e5200) Id say 3GHz is doable. First find out your max OC without raising the volts.

Do you mean there's no need to increase the CPU voltage for 3ghz(240*12.5) ?

You may or may not need to raise the voltage. I'm saying that, since it's already running at 60c, you shouldn't raise the temps any more by overclocking it. Wait until you get a better cooler.

You shouldn't have to raise the voltage for 3.0ghz. I'm almost fully sure of that. I had the same as mad for changing voltage. Needed a change at around 3.33ghz 266fsbx12.5 settings.

I reccomend reseating the hsf or checking to see if you got it snapped in correctly. I know I had a hard time doing this with the damn hsf. I'd reccomend taking out the mobo to make sure it's snapped in on the bottom if your not totally sure. Those temps are not normal for stock speeds, even at full load.

Also, if you have at least half decent air flow in your case, you don't need an aftermarket cooler if that's as far your going to push it. If you going to up the voltage or go past 3.33ghz, whichever comes first, your definitely going to need an aftermarket cooler. Well, highly reccomended that is.

wow surprisingly enough i'm actually getting an e5200 soon... let me know how it turns out anyway

btw, the required voltage differs on every chip, they are all different.

That's true, but from what I've been reading from other reviews, that's what the cutoff seems to be. Plus mines was similar to mad's. That's why I put I was almost fully sure. 3ghz is way below that.

I have been able to get my chip to 3.92ghz with 1.4 voltage, but it wasn't stable due to the board and mem divider being all weird. BSEL mod because of no voltage control. I know, after doing it, I don't reccomend this... LOL. I'm going to buy another board and better cooling to see what this thing can really do.

atm : 300fsbx10 @ 3ghz, idle temp : 28 degrees celcius stock hsf and voltage

i would just say 10% higher than VID MAX to be on the safe side

Well, 1.4v seems to be the highest and stablest voltage for the e5200. That's what everyone else seems to say anyhow. I really didn't see any huge improvement from there on. I was even able to do 1.38v I believe also. But BSEL mods are a hassle to do.

hmm well when i get mine i will just stick it at the highest VID that intel ships them with. if i get a low VID chip, and put it at higher vid voltages... happy ocing!

Yeah, you could do that. Well, just make sure you get a decent board to oc it with.

This voltage is an automatic setting, my MB set this value.

Don't know if this is of any help, but I have used fsb of 333 and reduced multiplier to 11.5 to run my E5200 at 3831Mhz and voltage is about 1.38v. Totally stable at this. I had tried previously to just increase fsb with 12.5 multiplier but could not get past 267 fsb without the system failing to boot.

MSI P45 Neo-F
E5200 (Wolfdale)
4GB Corsair XMS2 (Twin2x4096-8500C5 G)
Vendetta 2 with proper retention bracket (not tacky plastic press clips)

The Corsair memory was bought as 1066 as motherboard supported it. It's just standard 800 memory that takes well to overclocking not true 1066 memory.

download prime95 stress program and run it for 6 h if you get no erors probebly your system is stable
if you get error try as little as you can higher vcore (volts to cpu)
finaly ran again prime95

Visit here and see my overclock upto 3.05 ghz on stock cooler. Now the max temp. are 61-63C.

I am running my pc at: 10X 305 mhz with ram at 813 mhz.

FSB vol. is .1v and others are normal.
