Overclocking CPU

[gonchi1207]

Gonchi,

There are always risks for over clocking but mild and conservative overclocking leaves very little risk to your components. Overclocking should be done conservatively if you are new at it and in graduated steps with the tests above at every overclock increase. Generally if your overclock is bad, it will fail Memtest86 without entering your operating system so you reboot and make your corrections. Most good boards won't let you boot into a dangerous area, it will just stop.

For instance, my overclock in my signature is very mild compared to the experts here. I am on stock cooling and voltage and that's enough for me.

As an added precaution, get Core Temp and run it minimized with the temps showing in your task bar and monitor it closely. I try to avoid temps running Orthos that go over 70C. That's my self-imposed conservative limit for my E8500 chip.

I am not familiar with your motherboard so you may want to ask redduc for a more conservative beginners overclock to start with and try it.

ok, so the overclock redduc posted is conservative ? what i am most worried about is the 4890 since it is the most expensive part... but the risks are all 4 the cpu and mobo arent they ?

How about we drop back 10 and punt here?

You (admittedly) have no idea what you are doing, and are concerned about burning up your hard earned dollars.

No disreapect to the people advising you (they're all telling you good stuff, just maybe not all the good stuff you need to know), but you're trying to learn how to ride two wheeled bicycle for the first time, and you're doing it by reading a book ...that won't work.

Why don't you take a month off and spend the time reading and studying about overclocking, how it works, what you change, why you change it, and what to expect when you do change it.

There are many excellent overclocking forums out there and they all have great stickies and FAQs about overclocking.

Spend the time to learn, and you'll be a better (and safer) overclockeer.

Any errors in Memtest means you'll need to make adjustments to the vMCH, timings, or Vcore...

So if i get any error i post back, but should I post the information memtest gives about the error ?

geez, when i overclocked my core2D i didn't had all these problems Oo

i am so happy my i7 is easier to OC =)

I never admitted that i didnt know what i am doing, as a matter of fact i know WHAT i am doing, or trying to do. I am overclocking as the word itself says, increasing clocks, in order to increase speed, in order to increase performance. As you increase clocks beyond what are deafultely supposed to be, you need to increase the power that u give to the cpu mobo etc., thats why u have to adjust voltages, if u adjust voltages below whats necessary ur computer will lack of power, but if u adjust beyond whats necessary u risk hardware damage.

What i do not know, is HOW, to do it ( by this i mean, adjusting values to what value, etc. ) . and thats why i asked for help here. The point in my post is not to become a pro overclocker, is to get the most out of my PC, since my cpu is bottle necking my gpu, so i need to increase the performance of the cpu. Theres no point in reading overclocking guides, as you suggested, since no matter how much i read, it is only theorical, to learn properly u also need to practice what u read, and i do not want to practice with my PC, since like you correctly said, i do not want to burn my hard earned dollars, and there is much more probability that i burn it trying to overclock using my criteria, than doing what u guys say.



Redduc, by applying the settings you posted above, can my gpu get damaged ?

please can u post an configuration for an intermediate overclocking like 3.0 or 3.2 ,


why not changin the multiplier to 10x ?


thanks in advantage

these settings worked great ! ive been using them for a time and are great...

now i am looking forward to have the fsb set in 333, so i have a 1:1 divider between the fsb and the memorys....


some simple questions:

if i increase the fsb beyond the mems frequency theres no point in doing that because it will show no better performance?

it is bad for a computer that is stable overclocked to be on like 24/7 ,,

thanks

Why would you want to run the RAM underclocked w/ a FSB : DRAM ratio of 1:1 at a FSB of 333MHz (667MHz effective DRAM frequency) when you're running DDR2-800? At a FSB of 333MHz the FSB : DRAM ratio should be set to 5:6 for an effective 800MHz DRAM frequency. Change the (G)MCH Frequency Latch from 266 to 333, and the System Memory Multiplier from 2.50A to 2.40B = Memory Frequency of 800MHz.

 

[gonchi1207]

i do not want to run it underclocked but i thought that my rams where in the end 667 !!!!!!!!!!!!!

so i have 800 mhz ram,,,,

using my current fsb 320 mhz my temps wont go above 49ºc at full load in prime95 ,, so i have some space for further overclocking

however , my goal is 333 mhz since my computer is ON 24/7 so i want it to be stable,,, unless someone think i can push it a little further without compromising stability.


so for 333 mhz besides the mems adjustments you mentioned above,, should i adjust some other things? remember im running everything ( except for the ram that it was originally at 1.8 and now 2.0) at stock voltages.

thanks in advantage

 

[gonchi1207]

i checked my benchamrks i did some time ago, and realized that when running my q6700 at stock speed, my benchmark on 3dmarkvantage were 2000 points lower than now ( overclocked @ 3.2 ghz , 320 mhz fsb ) However, and here's the odd thing, in the windows 7 score i score 6.9 in cpu now with the cpu overclocked @ 3.2ghz ,,, and when i had it all stock, (2.4 ghz , 266 fsb ) i scored 7.1 ...

How is this possible and which benchmark should i take into account? ( most probably vatange is more reliable than the windows 7 benchark )

From Post #29...

Why would you want to run the RAM underclocked w/ a FSB : DRAM ratio of 1:1 at a FSB of 333MHz (667MHz effective DRAM frequency) when you're running DDR2-800?

Change the (G)MCH Frequency Latch from 266 to 333, and the System Memory Multiplier from 2.50A to 2.40B = Memory Frequency of 800MHz.

So in answering your PM, I already told you what settings you need to change in order to run at a FSB of 333MHz. But to reiterate... at a FSB of 333MHz = 3.33GHz clock, change (G)MCH Frequency Latch to 333, and System Memory Multiplier to 2.40B = Memory Frequency of 800MHz. Leave all the other settings the same as they were at 3.2GHz.

 

[gonchi1207]

i did the changes but my system wont boot. What should i do

also opened cpu - z and saw this :

this means the mems are 667 despite the fact that i payed for 800.

So is it worth to get 800 mhz or 1066 mhz for a gaming computer like this one ?

Question:
All of the computer detailed display shown in the previous screens are part of the Bios screen you guys are using or part of a program that reads all that info from your computer,
Last time I overclocked a computer was when I was younger about 20 years ago.
