***The Official E7200 Overclocking Thread***

[saitrix]

Here is my E7200, not a big overclock at all. Just going easy with it due to the temps. What do people think to my temps?

E7200
Artic Cooling Freezer 7 Pro
Gigabyte P35-DS3L
OCZ pc2-6400 Platinum

It's perfectly within safe range although it's a tad high I think considering the speed and the low volt you put it through.

 

[Dutch Guy]

Does anyone know why the E7200 heats up so hard when load is applied, I have watercooling but no matter how high I set the fan the temp just shoots up a split second after starting something intensive and drops as soon as I stop.

Is it because the contact between the die and IHS isn't optimal due to no soldering?

 

[saitrix]

It would make sense about it being trapped with the die so it can heat itself up really quickly.

Oh one question, which voltage is the real voltage, the one I set in the bis (1.3v) or the one that appears on cpuz (1.248v)?

Edit - How high can temps go and be safe?

CPUZ will be the more accurate I'd say, as it's reading from an internal sensor AFAIK. The 1.3v in the BIOS is what your board is aiming to supply, but they always seem to be slightly short... possibly intentionally erring on the side of caution.

CPUZ is the real voltage the CPU is getting, the voltage will drop under load which is a pain as under load you actually need more volts to run stable when the opposite is happening.

I would try 8x400Mhz = 3.2Ghz at default voltage with the memory at 1:1

I'll give it a go. Thanks

Perfect, that puts my mind to rest.

What's an acceptable maximum temperature under load? Sorry if it has been mentioned This is the overclock I've managed so far:

Hi all had this pc 6 month with the E7200 in, Just changed the case to a antec 1200 and what a different to my temps

before:- old thermaltake case

idle 35 'c
load 60 'c

after :- antec 1200 case

idle 20'c
load 40 'c

hell of a different

screenshot here.

E7200 OC to 3.8Ghz watercooled

 

[wolvers]

^at those temps with that voltage, I'd definitely be pushing her a bit more ^

 

[Dutch Guy]

before:- old thermaltake case

idle 35 'c
load 60 'c

after :- antec 1200 case

idle 20'c
load 40 'c

I doubt the difference in load temperature is because of a different case or is the radiator now in a totally different position?
Maybe the waterblock is seated much better now

 

[pauljen296]

the only problem is i have very bad vdrop. In the bios i set it to 1.4v but when the cpu at 100 % the volts drop to 1.328v any buddy know how to get round this safely so i can push it more.

 

[phinix]

What is the difference between Vcore and Vid?

Set it to 1.45V

And I think Vcore = Vid

 

[pauljen296]

i was under the impression 1.4 volts was max voltage for everyday use or is it different at these temps.
Btw i moved the double rad to the front of the case with fans pushing the air instead of before where the fans where pulling the air. I have also remove a single 120mm rad which seem to make a difference.

1.4V is the max safe voltage but the worst that is going to happen is that the CPU dies so if you can afford a new one if it breaks you can go higher.

I ran my E7200 at 3.8Ghz/1.475V for months without issue, I only recently lowered it to 3.6Ghz/1.4V as it is fast enough for me and now I have the 120mm fan on my rad at the lowest setting making it much quieter.
