LGA775 Core2Duo, Core2Quad OVERCLOCKING guide

[harrynowl]

So dropping my RAM down to 667 would increase stability in overclocking? Is that it? Sorry guys if I ask to many questions it's just my first time doing overclock. In your opinion what would be the perfect FSB for my Core 2 Duo E6750? Because the default is 333.

Thanks man! I would definitely gonna try that. But one question, I only have a stock cooler here and a generic power supply plus my RAM has no heatspreader, is it fine?

the perfect fsb is the highest it goes stable

 

and yes that would help stability

[Hephep]

And how should I know the highest stable? HAHAHAHA Man! I really suck at this. Any recommended application that monitors the temperature of my system? I have here from Gigabyte the Easytune 6 though I'm not really sure how accurate and reliable is that.

I like RealTemp and HWMonitor

Is that the HWMonitor Pro from CPUID you're talking about?

It is indeed

It is indeed

Okay thanks! I might do some overclock when I get a decent power supply and an aftermarket cooler since I only have here a stock cooler and a generic power supply

[Hephep]

Oh it will be capable, you might have some issues with stability, which can easily be fixed by decreasing the overclock. If you've had no problems so far however, just keep the overclock. And you should notice a difference in overall system performance with even a 540MHz overclock, though if you really wanted to, you could run a benchmark at stock settings, and one afterwards with the overclock to see the difference it makes, and if it will be worth it.

It is indeed

Okay guys after running cinebench, I managed to get this data with overclocking my Core 2 Duo 6750 also I finally set my RAM to only 800MHz during the overclock.

 

So here it is:

At stocked speed 2.66GHz

CPU = 125 cb

OpenGL = 41.06 fps

Temperature © = 44C idle, 65 max at full load

 

Overclocked @ 3.2GHz

CPU = 150 cb

OpenGL = 44.32 fps

Temperature © = 50C idle, 74 max at full load

 

So what do you think guys? Is it worth it to overclock it or should I just stay as it is? Also if you would recommend me to overclock, I might get some aftermarket cooler maybe the deep cool ice blade since that's the cheapest cooler I found. And assuming I would overclock it and I buy deep cool ice blade, can I run it around 3.5GHz? Thank you so much guys.

Worth it

 

What voltage are you currently at?

[Hephep]

Worth it

 

What voltage are you currently at?

Around 1.4v. I did not really set the voltage, it just automatically adjusted itself since it's around 1.1 to 1.2 when in stocked speed. And also how about my temperature? Isn't 74C at full load bad?

[terrytek]

So, I am considering to replace my Q6600 with an x5450 instead now since i don't think my CPU can handle  it anymore.Then I might put my Q6600 in my dad's system to replace the E4500 in it.

Your 680i board probably can't run an X5450 @ stock 1333 FSB if it's anything like mine was

Go to 1.3V for that kind of FSB and try temps again, 74c isn't too bad but 1.4V is quite high for your clock... I'm pushing 4.2GHz on my E8400 at that kind of voltage.

I looked it up and it said it can run 1333MHz FSB CPUs.

Okay, will do. Thanks for the help man, I really appreciate it.

Best of luck

 

My X5450 had to run at 2.4GHz to even get to Windows

 

It doesn't officially support 45nm CPUs either

Where's the best place to get one of these overclocking lga 775 motherboards?

Thanks man! I managed to set it to 1.264v and temperature goes down to 67C at full load during cinebench. Although although my score also dropped from 150cb to 147cb. Anyway I guess it's good since the temperature is now lower.

hmmm, might have to try this with my nforce 680i lt sli and my e2200 pentium d. my cpu is bottle necking my gpu currently as games i play are only using 60 to 75 % of my gpu and 100% of my cpu. problem is that with this board whenever i change anything in the bios it won't post until i reset the bios back to stock... stinking xfx products... lol before i do though i think i'll tear it down and replace all the thermal paste as this thing gets high temps sometimes.... it did sit in a garage for a few years before it was given to me. might play with my old pentium 4 too. it's running about 3.6 ghz, might be able to get more out of it. idk.

E2200 is core/Conroe, not Pentium D

[OpposingForces]

in both bios and cpuz it reports as pentium d ....... so idk. pretty weird then.

Pentium Dual Core and Pentium D were different brands

[OpposingForces]

ah gotcha. 

[Stukas]

This is my first rig and it was fun overclocking it

I have 
MotherBoard : GA-N650SLI-DS4L

CPU : CoreQuad Q6600(With BeQuiet Dark Pro Slim 2)

RAM : AENEON 333 Mhz

 

I it was an easy 3,245 Ghz ,with 1,3V on CPU and i set RAM at 411 Mhz , i just put a very little amount of Voltage to the other components like southbrige northbrige just to keep them pumped enough for the oc

also i check on FSB:DRAM with CPU-Z and it says 7:8,i dont know if thats ok,what do you think?

 

 

Any help is welcome cause i am new in overclocking

I did Prime95 for 12 hours and everything seems stable

[Dabombinable]

Running tests now, but I might have found the reason for my limited overclocks, and the solution. Will post SS and photos when I get the FSB above 465MHz stable. Note that the new NB cooling solution is working a lot better.
