Overclocking my E7200--> Current settings in OP.

[MentalIlness]

First off, I have read the sticky on this subject, and to be honest...while a lot of it makes sense to me, a lot of it don't.

I know these E7200 CPU's overclock really well, and I have been running at 2.53 ever since it was purchased.

My hardware:

What do you want to run it at?

I recommend something like 3200 or so. To do that set your CPU Host Frequency to 400MHz and CPU Clock Ratio to 8. CPU vCore can be set to Auto but that will likely give it more voltage than it needs (something like 1.3XX I think). You can set that to 1.10 or 1.15

I know some of them hit 4GHZ....but I would be completely happy with at least 3.6GHZ. Which these seem to do well on air cooling.

 

[edplayer]

set the CPU Clock Ratio to 9 (cpu host freq still at 400MHz). You will need more cpu voltage. 1.3 should work and if it does, I would start try lower amounts (maybe dropping by .025V every time). Or you could just try it at 1.25V (might even work with it lower)

Also you will have to change your System Memory Multiplier to get your ram to work at 400MHz (its rated frequency). That BIOS is a little confusing but you want a 1:1 ratio. Don't remember which choice it was (A, B, C, or D)

 

[MentalIlness]

Ok, I fell asleep last night, and never got to do this.

So going to start now, oh, and should I change my memory voltage ? If it is even needed.

No run the memory voltage at its stock rating. Your not overclocking your ram yet.

 

[MentalIlness]

Thanks happy, was wondering about that.

Anyone here with a E7200......"if you overclocked it" please post your hardware and settings.

I'm trying to get the most out of this CPU for the next few months. Then I will finally upgrade.

Ok, I am heading to the BIOS now.

 

[MentalIlness]

Ok, I'm in the BIOS, and the M.I.T settings are "grayed out" and is non-selectable.

Why ?

I have never been in this BIOS until now.

So how do I ENABLE the M.I.T settings ?

Since your cooling seems good enough, I'd give it max volts (1.36250) and max NB (1.3) and try 4.0GHz. Then work your way back from there until you get stable at the highest possible frequency and then work on getting the volts down.

How is this for cooling ?

Oh, and the option to "ENABLE" host control.....is grayed out. Non-selectable. Why is that ?

 

[TridenT]

Your vcore is really low for some reason...

Anyway, 1.325-1.35v @ 9.5x375mhz works for me. It gets you at 3.56Ghz and is stable for me. Temps are reasonable for my setup. I don't try to push the 400mhz because it requires a lot more vcore just for an extra 200mhz.

Yes, I noticed that too. Ive had this CPU for about a year now. And it has been that low on voltage ever since day one of installing it.

Never "EVER" had a problem with it either.

Oh, and the screeny says case opened.....But it is "not" opened. The side panel is on. P182 case.

 

[MentalIlness]

Anyone know why my settings in the BIOS are "grayed out" ?

 

[VirtualLarry]

Did you hit CTRL-F1 at the main menu list screen?

 

[MentalIlness]

Did you hit CTRL-F1 at the main menu list screen?

Yes sir. And it does absolutely nothing

 

[VirtualLarry]

Yes sir. And it does absolutely nothing

It enables hidden options on Gigabyte BIOSes. You have to hit it at the main menu screen (listing each of the sections of the BIOS), and then navigate to where the advanced CPU settings are, and more things should open up to you.

 

[edplayer]

from that picture I see "Advanced Clock Control" greyed out and that is correct. It is a title and the options are underneath so it there is nothing to select (on that line).

under "Standard Clock Control" you want to select CPU Host Clock Control and set that to enabled. That will allow you to change the front side bus (FSB). There are lots of different ways you can set it up but I would start by setting to to the 400x9 like posted above (to get 3600MHz). The 9 you select in CPU Clock Ratio (already set) and set Fine CPU Clock ratio to 0.


as for your voltage, it looks fine. I have a Q9550 and its VID is 1.25. It is not one of the better ones. I have seen some Q9550 at 1.10 VID. Those (quad cores) are usually higher than dual cores like your cpu so your 1.076 is good. If you want to do 3600MHz, that 1.3V range is probably more than you will need. With a good cpu it should be able to do that in the 1.2~1.25V range. Try 1.25V I recommended use a 9 and 0 multiplier (versus 9 and 5 like you have stock and Trident posted) because you can get a higher FSB getting you more performance. You can go even higher on the FSB (maybe 500MHz or even more) but that would require more tweaking and 400 should be easy without any changes.

Yes, you are correct. However......I "cannot" select CPU Host Clock Control to "enable" it. The only thing on that screen that I can select, is what is highlighted in red.

I cannot select anything above Advanced Clock Control.

 

[MentalIlness]

Well, I fixed it. Removed the battery for a few minutes, then put it back. Booted into Windows with one stick in slot 1....then booted into Windows with the other stick in slot 1.

Everything in the BIOS is now able to be changed. No idea how it came to be like...."read only"
