Need advice on E7200 Safe overclock with Asrock Mobo

Last response: in Overclocking
Share

Hi everyone ,

I have read some of the threads here regarding these processors and how good they are to overclock, i read the guide on how to overclock Core Duo's but even for a noob like me it starts getting complicated lol.


To simplify things a bit I plan to just use the ASROCK OC util , can anyone recommend the best way to o/c without frying RAM or increasing the CPU temps to much bearing in mind stock intel fan (see detailed info below ).

Has anyone got successful oc with the ASROCK motherboards that is stable and by simply using this utility and with stock fan ?.

The Memory im using is not the best but all i can afford at present. I am a bit reluctant to mess with voltages too much without being fully clear on what is happening , I know a few basics from the guide and that temps can be affected by increasing voltages.


The Intel E7200 Spec for Thermal variance is 0.85V – 1.3625V. is this relating the vcore values ?

Thermal design power is 74.1°C , is this the max temp that one of the cores can reach ?


Any help is appreciated ...

So seeing no replys which is my own fault for just appearing with a whole lot of questions and probably like others wanting to jump in too soon for which we all seem to do :sweat: 

I set about reading the o/c guide for dual cores again and re-reading it again here is what I managed to get without messing with voltages and using the ASROCK utility.

I ran prime95 and no errors, i could have gone further but as this appears stable i will wait until i get better cooling for the CPU and Northbridge. I left the machine on whilst doing normal things and even played some ArmA2 and thats intensive on system resources.

Currently running 24hr testing but have concerns over the core temp but overall cpu temp seemed fine

I can see why overclocking is additive now :D 


Now need to budget for a decent CPU cooler at right price and consider putting cooling on the RAM and Northbridge, then use the bios to do the overclock.

Sometimes when you are waiting for a reply, you just need to be patient.

Look for a guide for your particular motherboard. The stock fan for the 45 nm Core2's is adequate for stock speeds - or as fast as you can go without increasing your core voltage.

The Memory im using is not the best but all i can afford at present. I am a bit reluctant to mess with voltages too much without being fully clear on what is happening , I know a few basics from the guide and that temps can be affected by increasing voltages. said:

Make sure that you are not overclocking your memory by accident. You want to keep for memory frequency equal to your FSB, or your memory clock equal to twice the FSB for a CPU:RAM ratio of 1:1 as shown in the memory tab of CPUZ. You show a ratio of 4:5, meaning your RAM is running a little faster than your FSB. The only thing that is accomplishing is probably limiting your CPU overclock.

The Intel E7200 Spec for Thermal variance is 0.85V – 1.3625V. is this relating the vcore values ? said:

Somewhere in that voltage range is your chips VID. That's sort of the "stock" voltage of your particular CPU. It's what the CPU will program your power regulator on the motherboard to provide. Lower is better. While not great, your 1.213 volt VID is pretty good. 1.3625 volts is also Intel's recommended maximum voltage.[/quotemsg]

Sort of. That's the recommended max temp to avoid damage. I set my motherboard thermal alarm for 70 C. That will give you BIOS type beeps when your temps are higher.

For a serious overclock, you will need better than stock cooling. This is pretty popular (and a great deal):

Many thanks for the reply and advice :) 

I have now been running 48hrs at this o/c , I read a few guides on bios terms and meanings and have learnt alot since posting up. The manual for this Asrock is not the best but the board does allow some overclocking settings and I have now done the overclock in bios and run prime95 with no problems

I am aiming to get 1:1 fsb CPU/RAM ratio, I will take your suggestion on the cooling side and get a better CPU Cooler and some artic silver in the next few days then will see if I can get to 3.6Ghz stable after that.




Overclocking Master

Now with your FSB:RAM ratio at 1:1, you have room to push your FSB to 400 MHz while still staying within the capabilities of your RAM. You may then be able to squeeze a little more out of your RAM by increasing the RAM voltage .1 or .2 volts (up to a max of 2.2 volts.
