E7200 What overclock can I expect?

[Kingbee13]

Newegg just shipped my e7200, was wondering how much overclock I can expect on a new Gigabte EP45 UD3R

cooling will be done with a Tuniq Tower.

I would be happy with 3.6-3.8 of course the goal would be to break 4ghz

Welcome to the forums.

I'd say 3.5 - 4 GHz, depending on some luck & vcore.

I would bet you're not going to be able to break 4ghz stable. Depending on your vid, I'd think 3.6 would be do-able depending on the voltage. With the tuniq I wouldn't be afraid of bumping the voltage up in the bios at all.

 

[error8]

I have the impression that any E7200 out there can touch 4 ghz. The problem is that some get there on low vcore and some with high vcore ( like mine for example). In any case, your E7200 should touch 3,7-3,8 ghz with that Tuniq on safe voltage ( bellow 1,4 V ).

 

[geokilla]

Some people have managed to get 4Ghz stable, but you need a low VID. My E7200 has a VID of 1.2V and topped out at the speed seen in my sig. It can probably go a bit higher, possibly topping out at 4Ghz if I gave it even more volts and spent more time OCing.

 

[nyker96]

3.5-3.8 is more common. 4 if you lucky.

I can do 4.037ghz stable under 1.4 vcore and under 1.4 vtt, but temps are so-so: ~60C during load... I'm going to have to lap, or reposition hsf + get different paste, or just reseat hsf--> you might have to do the same. Now, I'm running contently @ 3826MHz, 1.35 vcore, 1.2 HT/vtt, 1.2 NB, 1.5 SB. my temps are 43 idle on both cores (lower with case unopen, and 54C @ load
For me, it took 1.24V HT/Vtt, and 1.36V NB to get my fsb to 1600, but having @ 1700MHz is a really stable point- I got a 100mhz increase with drastic voltage differences- all but cpu are the lowest my board can go... play around, but stay within safe thermal/vcore/vtt ranges!

I was trying to give the average. Yeah, I'm sure just about all have a shot at 4, but with the vids these things are coming with lately, its unlikely without a huge bump in voltage. A lot of people aren't comfortable with the voltage you're pumping into yours, be it safe or not. Curious, I know I read your posts on your 7200, but @ 1.46 in the bios, what is it idle and under load in windows? What's your temps as well? As cheap as these chips are, I might be inclined to see if mine can do that w/ a 1.2 vid.

I have 1,424 V under load and 1,432 V idle, because EIST is enabled in bios and I'm on "balanced" power setting in Windows ( the cpu runs at idle at 2525 mhz, with a multiplier of 6 ) .

I have a good VID on mine ( 1.125 V ) , but for 4 ghz stable, 1,46 V is necessary. Idle temps are 34 C ( although that doesn't mean anything at these chips) and 67 C full load OCCT cpu stress test. It got up to 74 C in Linpack, but only there, never in games or anywhere else.

I never said that is safe to pump 1,46 V in your E7XXX chip, nor encouraged anyone to do so. This is just what I'm using on mine and I feel comfortable with it. My advice is, for those that oc this chip, to stay bellow 1,4 V, since that is the "safe" voltage, that people are using, without having problems, until now at least.

 

[Kingbee13]

Thanks for all the great responses!

My chip should arrive tomorrow, and I'll let everyone know how it goes, depending on the VID of my chip I may go for 4ghz, but I'm not sure if I want to tax the entire system that much with fsb above 400 (thre dreaded VTT), so maybe 3.8 will be an easier goal, I'm not too concnerned with high(ish) core voltages and temperatures, as long as its completely stable and doesnt burn down the house next week

I usually upgrade on a yearly basis (or less) so deminished CPU life is not a concern for me at all, and I've never had a CPU die from longterm overclocks. (and I do have some old venice core athlons64s still in use that have been overclcoked for years) but I suppose the newer manufacturing processes are more sensitive to a slight voltage increase

The last question I have is subjective, but from anyone's experience, how much of a difference will I notice in performance coming from an E2200 OC to 3.0ghz, on a nividia 7100 chipset?

I am guessing that the 7100 is holding back performance (especcialy memory bandwidth performance as there is no memory voltage adjustment in the bios) but I am using an ATI 4850, not the onboard video so I'm hoping the P45 board and cpu with more speed and larger cache will feel "snappier".

 

[formulav8]

I had a e7200 from newegg.com and the best I could get completely stable was 3.6. Some others on other furums are having a hard time getting 4ghz as well from the latest stepping. Unless your ok with higher voltage increases I wouldn't expect 4ghz or higher. Of course though each cpu can be different.

This is just my experience and therefore it doesn't relate to all cpus. Still 3.6ghz is fast. I have a e5200 right now and it is a ocing dog. 3.3 is about all I can get without major increases in voltage. But others has had a better experience with them. So your cpu could or could not have alot of headroom.

Just my experience and opinion.

Mines @ 3.8 w/ 1.45volts under load hits around 68-70*C. I've only had it a week and hope to get a new cooler pretty soon. Currently I am using an ancient XP-90 cooler with the $7 socket 775 bracket adapter. I'm not sure what a "safe" voltage is but high 60's up until 70 seems ok to me for a high OC. I suppose if I fry the chip I'll be out $100 but that's a risk I'm willing to take.

 

[Kingbee13]

Well my CPU arrived yesterday, so I set out to see what I can get after running into problem just installing windows (IDE DVD ROM) which I still haven't quite figgured out, (the windows install takes forever) it may be the j micron ide controller I guess its time to get an sata optical drive...

At first I was ableto hit 3.8 but the temperatures I wa seeing were quite high 70-80c under load, I knew this wasn't right and had to remount the heat sink, the tuniq tower is not fun to work with if you have large hands.

After reseating the heat sink and turrning it arround to promote better air flow my results have been much more encouraging as it stands right now I'm getting 3.8 at 1.344 idle and 1.312 load and seeing temepratures of about 59-64.

I'm still not sure if 4ghz is going to be possible without insanely high temperatures/voltage, but I'm about to try!

 

[error8]

Quite high temps you got there at 1.31 V. What are you using to measure your temps and what is your room temp?

 

[Jyve]

if those are load temps then, yeah, its a bit hight but nothing to be too worried about. If those are idle temps then you've got an issue.

 

[Tempered81]

you have a ton of room for temps with an e7200:

45nm Desktop CPUs
Model Tj Max (Stepping unspecified)
E8000 and E7000 series 100°C
Q9000 and Q8000 series 100°C
QX9650 95°C
QX977x 85°C

compare it to the original core2s:

65nm Desktop CPUs
Model Tj Max (B2/B3/L2) Tj Max (G0/M0)
E6000
and E4000 series 70°C 80°C
X6800 75°C 85°C
Q6000 series 80°C 90°C

 

[Kingbee13]

I'm using Everest to measure the temps, room temp is about 70 f

Edit:

The E7200 is revision M0

Whats software/settings should I use to monitor the core temps?

 

[Tempered81]

newest coretemp or newest realtemp as long as tjmax is 100C or core temperature + distance to TJ max = 100C (not 95c or 105c)

 

[Kingbee13]

OK, real Temp 2.7 shows readings about 5 degrees cooler than everest and core temp 0.99 agrees with everest temps


Real temp distanceto tjmax and temps total to 95C

Edit:

After adjusting REal Temp tjmax to 100c all three programs (Everest, REal Temp, and core temp) all agree on temps

 

[Tempered81]

so what is your load temp now that all three agree?

 

[Tempered81]

if it's 64C, then you have about 36C before your cpu goes boom (jk - shuts down or throttles) . IMO you have about 11-12C til you reach about ~75-76C which is 24C distance to TJmax and are relatively safe. Virtual Larry would say you have about 25C left til you reach about ~89-90C - hes ran his e2180's at 90C. Others will have different opinions on what is safe.

I had prime95/orthos get my C0 E8400 to about 78C @ 4500mhz before. Linpack would have been much worse ill bet.

 

[Kingbee13]

Load temps are 74C seems pretty high to me, I may reseat the heatsink

I think I'm having problems with case air flow as well, due to the motherboard layout I had to position the Tuniq tower so that it the "Solid" side is facing my rear 120 exaust fan, which is certianly not ideal

So your Tuniq sucks air out from the exhaust case fan??? That is horrible indeed.

Anyway, when you will reaseat it, clean it and reapply thermal paste. And find a way so it wont have to "fight" the case fan to get some air in it.

Actually it was worse than that the case exaust fan was almost up against a complete solid wall on tuniq tower, I ended up having to remove the upper most heatsink of the motherboard apply the tuniq tower (then I was able to reapply the mobo heatsink) in the proper orientation where I'm getting airflow from the front case intake fan through the cooler and then through the exaust fan of the case

now I'm seeing load temps of 58C

Well, that's much better. Now you can do some serious overclocking. :laugh:
