View Full Version : How far can you OC a notebook?

I ask this because twice in the last week I have heard numbers I do not understand. Once on another forum and once here. On the other forum became very clear poster was mistaken and likely had from little to zero experience. Here it just happened. Talking about taking a Q9100 2.0Ghz up to 2.7Ghz "no problem"?

I am very suspicious of these numbers? I am not an expert on OC'ing and am not trying to present myself as one. I have only done it on two notebooks.

I can only squeeze a 500Mhz OC out of my current 2.53hz and I do have some stability issues. Basically my highest "stable" OC is 320Mhz so 2.53Gz becomes 2.85Ghz. Ram goes from 800Mhz to 900Mhz. You see when OC'ing the FSB the RAM OC's with the CPU. And on notebooks we can't adjust the FSB ratio. I think the RAM is what limits my OC. But that is just a guess. But it is a guess that is heavily supported by posts from the OC'ing community. 900Mhz to 950Mhz is about the max OC on PC6400. And remember we don't have the ability to increase RAM voltage to increase stability? These are not desktops?

OK so the system and CPU referred to on this site was a Asus W90 w/Q9100 going to 2.7Ghz no problem? The member who said this was Heaven. Like I said I am not an expert but I need Heaven or anyone to explain how this is done "no problem"?

OK taking a 2Ghz on a (266Mhz core) 1066Mhz FSB and since you can't change the multiplier up. Means to reach 2.7Ghz the new FSB is going to be (360Mhz core) 1440Mhz. So the RAM will go from (400Mhz) DDR 800Mhz to (550Mhz) DDR 1100Mhz.

I do not see any notebook PC6400 being stable at 1100Mhz. I find it much like when people talk of cars and give impossible 1/4 mile times.

Someone please respond. Unless someone teaches me something I will be forced to file Q9100 easily OC to 2.7Ghz as fantasy.

Furthermore the individual CPU's OC'ing ability varies from CPU to CPU so I find the comment "easily" OC'able to 2.7Ghz questionable.

I do hope I am wrong as I could get a better OC if I am. But I have doubts for the reasons I have said.

To all you buyers. The ability of the W90 and some MSI's to OC stock. While nice is not necessary. You can get free applications to do on your own.

A little math. 2.53Ghz to 2.85Ghz is a 13% OC. 2Ghz to 2.7Ghz is a 35% OC. Desktop guys are struggling with 25%? And rocket man thinks 35% is no problem?

The numbers do not add up!;)

i hate to burst an OCers bubble...but i highly doubt it was OCed that much (i wish)

*lights a torch* I call shenanigans!! *sharpens a pitchfork*

35% OC in a desktop would be impressive, let alone easily in a notebook!

especially at stock cooling

OK so the "myth" is busted?

I can see higher OC's with Santa Rosa because you can put in 800Mhz RAM will run at 667Mhz so maybe more room to OC. Still not 35%? But well? But the comment was not about Santa Rosa.

Santa rosa wouldnt get 35 percent either... a little nitpicky today powerpack? haha just kidding... :)

Santa rosa wouldnt get 35 percent either... a little nitpicky today powerpack? haha just kidding... :)No just thinking if I could under run my 800Mhz RAM at 667Mhz I could push it more? Yea yea I know not going to happen. But my 800Mhz as said 900Mhz tops suicide runs 950Mhz? Just thinking. And I am only trying to get 20% OC. I am not greedy.:p:D:)

And yea 35% is just nuts. So I agree.;)
