Please help me get my e5200 to 4.0GHz

[ibex333]

Well I was running very stable at 3.0GHz but now it's time to go higher...

I left everything on auto in BIOS and was able to go to 3.25GHz. Anything higher and the system would not boot. I then went up higher and higher in small increments increasing the voltage with various results.
I was eventually able to achieve 3.75GHz at 1.362 vcore. My temps are around 47 and 38c in RealTemp right now(idle)... and around 52c load.
I dont want to increase the voltage since the 1.362 is max for this CPU according to specs?

Any advice on how I can go higher? My mobo model is in my sig. Thanks very much.

EDITED...

1.36 V is the maximum voltage intel is stating for this chip, so, 1.62 V = dead chip in no time.
Very few E5200 chips are hitting 4 ghz, on air and within the safe voltage area. I would guess that a 3.8 ghz is much more realistic. See what 1.36 V is giving you, that is, if the cpu is still alive.

Thats freakin crazy! 1.625v. Hey its a $70 chip. Overvolt till you see a puff of smoke then back off .009 cpu voltage.

Sorry.. I gave you the wrong values... I was at 1.362v !!!

Just tried running prime 95 with my settings above and immediately got a bsod with a restart.

Tried other speeds and settings... Apparently anything higher than 3.5GHz or so gives me a BSOD when running prime...

I went to 1.350v and 3.5GHz and now I am stable in Prime. (ran for only 3 min for now)


Should I be messing with any other settings in BIOS like SPD? (I currently have it at 2.4B)

I read the stickies here, but my BIOS is somewhat different...

more voltage is whats going to get you from 3.7-> 4.0g. Someone might have an idea or other tricks, but afaik you'll need more vcore.

My E5200 got to 3.5GHz before I didn't want to push the volts any higher. Tried for ages to get 3.6 stable but as I pushed up the volts it was just getting too hot on air, and never did find stability.

But you're right. . .3GHz just isn't trying hard enough =)

Question:

Are CPU-Z readings supposed to fluctuate? It keeps jumping between 1680 and 3500 MHz....

You need to go into bios and disable power saving features. Your cpu is powering down to lower speed to save energy. It is best to disable those features because Ive read it can cause unstable oc'ing.

ive got mine to 3.3ghz at 1150FSB on a XFX 680I LT Motherboard.
I can get it higher but this board has a bad problem with vdroop and it will run fine for a while til the voltage droops then it auto locks up and my Voltage is a 1.45V and its been like this for bout 6 months

Not exactly. As long as he didn't changed the multiplier from bios, there is no need to disable the power saving features. I have my q6700 as I speak at a chilly 2100 mhz idle and it increases to 3.5 ghz whenever there is a stressful situation. No instability to report at all.

4Ghz seems a bit unrealistic for an e5200

And you are running 4 sticks? That's really pushing the Northbridge

About 10% of the E5xxx will crack 4.0GHz. Most will top out around 3.5GHz.

The E7xxx line is good up to about 3.7GHz, with 20% of the population capable of breaking the 4.0GHz barrier.

I got my brothers E5200 to 3.7 GHz @ 1.325v bios setting (actual, idle 1.3v, running OCCT 1.28v), with ambient temp of 30C peak CPU temp is 65C running OCCT. Cooler is an AC Freezer 7 Pro. Stable for 24hrs OCCT & 48hrs+ F@H.

He seems to have a pretty good chip , it could go higher but I don't think the extra voltage, heat & power useage would be worth another 100-200 MHz it might do.

Personally I wouldn't leave any voltage on auto & I didn't on my or my brothers rig, at least on Asus P45 (& probably P43 too) mbrds they heavily over-volt on auto, don't know about Gigabyte. Still better knowing what voltages you're running.

If you're at the max vcore you want to go then that's the best CPU speed you'll get, just check that you're not overclocking your RAM too much giving you a false CPU ceiling (you haven't mentioned RAM speed or dividers). Don't relie on SPD or auto settings for RAM timings (unless confirmed right in CPU-Z) & RAM voltage, they often get it wrong.

Anyhow, as mentioned you'd be very lucky to hit 4GHz with an E5200.

Where do you find statistics like that?

I build them for fun. 23 rigs with E5200, 6 rigs with E5300, 4 rigs with E5400, and 7 rigs with E7400. Most were bought during Fry's anniversary sale week ($80 combo deals). The $80 R0 7400s @ Micro Center have consistently hit +3.8GHz with 1.36V in BIOS. The best 7400 is Orthos and Linpack stable @ 4.2GHz with 1.32V CPUz.

No I have 2 sticks 2gb each. and it's fast good ram

sorry for bumping so late but I was away at work...

I cant make sense of my ram setting in BIOS.. What is 2.4b, 2.6c and so on? I can see they run ram at 1:1, 5:6, and so on, but I cant try them all by trial and error because I don't want to kill my hardware I need to know what I am doing. I opened the manual but it doesnt touch upon this topic.
