My Posts Are Simple

Posted by driveout on February 6, 2011

To everyone who thinks i have not covered the topics enough dont worry as i add links to my posts incase you would like to learn more about it. The reason I do that is I try to keep my posts simple with out overflowing to much information at one time. I mean who likes to read pages and pages about stuff. I just try to get straight to the point, if anyone has any questions just comment and ill get back to you. Like mentioned in posts if somethings not clear please check out the links I provided.

Coming Soon full guide with pictures on how to overclock !!

In Depth Overclocking Continued

Posted by driveout on February 6, 2011

FSB stands for Front Side Bus, this is what connects your cpu and ram together allowing for information to flow between them. Actually the fsb goes from the cpu to the northbride chipset but thats where ram and video card meet up. The difference between using FSB and Multipliers is FSB also effects your ram speed while the multipliers only change your cpu speed. How this works is FSB x Multipliers = Cpu speed in GHz. This means while overclocking with FSB not only does it change your CPU speed but also your ram, because of this you have to take a few extra steps in order to overclock successfully.

In this case using the FSB is similar to using the multipliers you still raise it by little increments. First of a little trick you have to do is lower the memory speed. Say stock is at 1066mhz at 2.1v lower the speed to 800mhz leaving the voltage stock at 2.1v. What this does is it gives you overhead room to work with because remember the fsb raises both the cpu and ram speed. If you think about it once you start overclocking the cpu speed your ram will go up as well and will reach the 1066mhz you started with.

So now its time to overclock what you do is go into the bios (basic input and output system). The way to get into it is press delete on boot up. Once your in it find the fsb speed and start to raise the mhz say its at 200mhz, raise it to 203mhz. Leave the cpu voltage at stock now save and reboot, once booted up run prime 95 and hwmonitor. Prime95 to test for stability and hwmonitor for temps oh and also its a good idea to get cpuz to check all the specs before and after overclocking. Once prime had ran for around 1 to 3 hours stop it, go back into the bios and increase the mhz some more say to 208mhz, keeping the voltage the same save and test again. Do this until you reach the maximum until you cant go any higher with out upping the voltage. Remember to monitor temperature at all times. When the maximum has reached and your at 218mhz and cant go any higher now its time to up the voltage by a little bit. After each raise and voltage change make sure to test. You shouldnt really have to touch the ram voltage as once it goes past its stock speed which is 1066mhz then you might have to but thats overclocking the ram so we will get into it on a separate post.

Like mentioned before the ram will go up as well if it goes up to high make sure you lower it. Theres a separate feature for overclocking the ram. Either way theres a few options you can do a FSB ratio which means whatever the CPU is clocked to the ram is less i think its 80 percent of the cpu overclock. Another thing that can be done is overclock the ram as well while overclocking the cpu using the fsb. What I recommend is lowering the mhz on ram and safely overclock the cpu. Using the same example as above say you went from 218mhz to 250mhz and your ram is at 850mhz but it suppose to be at 1066mhz what you can do then is clock the ram speed separately and raise it to 1066mhz. A good tip is to overclock one part at a time as then if a problem occurs you know where it lies. I know that this might be confusing to some of you especially people who have not done it at all so I found another guide that might help. http://www.geekstogo.com/forum/topic/11177-how-to-overclock/

Finally the final result, how you calculate it is 250mhz x 15x multiplier = 3.7ghz cpu

There you go guys make sure to check out how to overclock with multipliers as theres some useful info in there. Hope everyone has fun overclocking and be careful not to burn anything up. GOOD COOLING IS NEEDED !!

In Depth Overclocking

Posted by driveout on February 5, 2011

This will be a more in depth overclocking guide/tutorial. I will try to do the best in explaining everything but you must understand i might forget something. Anyway lets continue on ..

First of overclocking can and will shorten your CPUs lifetime. Either way if you have good cooling or not the CPUs lifetime will be shorter, that does not mean it will go out on you. Usually most people dont even get to see the end of their processors as every 3 to 5 years you upgrade to new components. Although good cooling will keep your CPU from burning up and help it maintain good temperature allowing you to overclock. This is a must if your going to overclock a aftermarket heat sink/fan is needed for the cpu. The stock heat sinks will not keep up with the temperature and you will burn up your cpu. If you wonder what are some good aftermarket heat sinks visit http://www.frostytech.com

When overclocking you need to download a program to benchmark your overclock in order to see if it runs stable. The program thats needed is called Prime 95. What this program does is it puts stress on all cores of the cpu testing if its stable. What you do is let this run for about 8 hours or overnight and if the computer does not crash then it means its stable. On the other hand if the pc crashes in one hour or so then its unstable.  Now there are 3 options to choose from in the software, I would say run all of them for at least a few hours to make sure everything is stable. With this i would also recommend getting hwmonitor program which reads your temps. This is important so you know how hot the cpu gets.

Lets see theres two ways to overclock, one way is to use the multiplier and the other way is to use the fsb. The easier way is to use the multiplier. In order to do this the cpu must have unlocked multipliers with out this its not possible. The black edition cpus come with unlocked multipliers while the normal ones do not. In this case if your cpu does not have the multipliers unlocked you will have to overclock using the FSB.

I will cover the easier way first which is using the multipliers. If you have a AMD CPU I recommend getting the AMD overdrive software which allows for overclocking inside windows. This means you do not have to go into bios at least till later on. First of open up HWMONITOR to watch the temps, next either go into the amd overdrive software or the bios and find Multipliers it will have an X next to it, such as 15x. Now check at what the cpu voltage is at now and check what the multipliers are at. That way you will be able to tell how much you have went over. Okay leaving the CPU voltage at stock raise the Multiplier by .5 or even 1. Heres an example say its 15x raise it to 15.5 or 16x.  If you doing it in AMD Overdrive program you can monitor the temps at all times, if in bios you have to save and let the PC reboot. Either way once you have saved the settings open up prime95 and run a torture test and pick In place large fft option. Let that run for about and hour or three. Make sure that your are monitoring the temps while prime95 is running. You do not want to burn up the cpu if it gets to hot click on stop and end prime95. If all goes well and the pc does not reboot, stop prime95 and go back into the bios or Amd overdrive and increase the multipliers once again. This time you can increase it again by .5 or 1x or even 1.5x , as the tests pass you can increase by more to speed things up. Once you reach a spot say your cpu stock is 3.1ghz at 15x multipliers you are now at 16.5x and at around 3.5ghz and the test fails and fails. What you need to do now is go into again the bios or amd overdrive how ever you decide to do it and up the cpu voltage by the least amount there is which I believe its 0.25v. Save it and test again if it fails go back into the bios/AMD software and up the voltage some more. Once your satisfied with the overclock say from 3.1ghz you have overclocked it to 3.8ghz and you happy with that run prime95 for 24hours to make sure everything is stable. If its not either lower the multipliers or up the voltage. To finish the example say stock voltage was 1.31v by the time the overclocking was done at 3.8ghz the voltage is at 1.42v.

This will show you the prime95 and how to use it http://www.playtool.com/pages/prime95/prime95.html

What the AMD overdrive program does is you can play around with the multipliers and voltages with out going into bios and rebooting everytime. When using this just change stuff in the program and save it and test, once you have reached a successful overclock you then go into bios and set it up the same way you had it in the program. That way you know it will run fine once changed in bios.

Now if you go straight to bios and start overclocking there you might run into a problem where your pc wont boot up again. Thats because you have overclocked it to much and it doesnt have enough voltage so it wont start. In that case you have to look on your mobo and find cmos pins. They should be somewhere close to the battery. Once you find them take a jumper and set it on the pins this will clear your current bios settings, changing it back to normal.

I am not sure if Intel has a program like AMD Overdrive so i cant say anything about that; just use the bios, and a few tips each CPU has a listed max voltage try not to go over it. Go on your CPUs website find your model and see what the voltage is for it. Try to stay between the stock and the max voltage. Of course you can go above the max but I dont recommend that, But if your into overclocking and like to play around with stuff go head and try it out just make sure you have a sufficient amount of cooling.

I dont want to smash everything together as I want the posts to be easy to read, therefore the next post will be about overclocking using the FSB. Enjoy and have fun overclocking !!

In case my guide is hard to understand heres a very good site that explains it well http://www.wikihow.com/Overclock-a-PC
