G72gx-rbbx09 - Overclocking and Heat

After debating between the Asus g60vx and the MSI 1651 for quite a while, I ended up going to Best Buy to check the g60vx out, and saw the g72gx. I instantly fell in love. While it's less portable (I can deal with something a little heavier if I have a good case), the specs are awesome (especially the 09 version), and I rather like the design. I now wish to buy the g72gx-rbbx09, which is only available via the Best Buy site, but it is currently backordered. Oh, well, it will just take a little longer to get here.

Anyway, I was wondering how easy it is to overclock the Q9000 (only 2.0 ghz, wondering what speed I should OC to...maybe 2.4 or 2.5?) and 260m (I plan on just getting it to the base stock configuration since the 260m apparently comes underclocked for some reason); I've never OCed anything before. Also, are there any heat issues with this model in general or when it's being OCed? Btw, what would be a good case for this laptop? It has a screen size of 17.3", so I'm not sure if typical cases able to hold 17" laptops would work out. I may be wrong, though.

 

The only way to know is to find out. Other people on the forum have managed to get almost 2.8ghz out of a Q9000 and 3ghz with the Q9200! Once you have it download HWmonitor to check temps, Prime95 to stress test the CPU, RMclock to undervolt your CPU to save power and cut down heat, setfsb to OC with and finally CPUz to make sure your OC has worked and to check fsb speeds etc. With this assortment of OCing/monitoring/stress programs you are good to go.

As for heat issues I think the g72 is fairly new so there isn't much feedback yet but considering it is 17" it should deal with the temps from the Q9000 and 260M quite well enough. The G50/51 I believe had heat problems with the 260M but that is a much smaller 15" chassis

 

keep in mind the laptops cooling will be your bottleneck.

 

Thanks for the info on all those programs. How exactly does undervolting work? Will it effect performance at all? And what did you mean by your comment SwiftSnipeR?

 

Your CPU will use a certain amount of voltage. What undervolting does is get rid of the excess unneeded extra voltage that is being used to drive the CPU at a certain clock speed where it is not needed. For example my Q9650 without undervolting will use 1.15 V at stock 3ghz however I know through undervolting that it only requires 1.0375V at that speed to run perfectly stably with 10-15C less hot under load. Undervolting does not damage your hardware in any way and will boost battery time and the life of the hardware as it will run less hot. Have a read on the forums about RMclock and become familiar with it as it is an essential great tool.

Also if the cooling in your laptop is limiting say your GPU OC a CPU undervolt will give you that valuable cooling headroom needed for a higher successful GPU OC.

 

wow 2.8GHZ outta a Q9000? dam that high, i can only manage 2.53GHz...

 

@SACH7002

What are you using to overclock your Q9000? Are you just using setfsb with the PLL (ICS9LPRS929AKLF)?

 

i am indeed using SetFSB.

on my G 51Vx-A1, i use the clock gen "ICS9LPR604AGLF"

notice the difference, after ICS9LPR, i have a different number/letter assortment.

 

3GHz? Gulp... that is insane...

 

Hehe maybe but perfectly achievable! I think the qx9300 will give 3.2-3.3ghz also Personally my nice cheap Q9650 gives 3.33ghz in my 15" laptop

 

Maybe I should just go to 2.5 ghz since I'm so new to the process.

 

if you want 2.5 ghz maybe shop around for a good deal on a qx9300. Then if you wish to get more performance from it 3ghz should be easy to reach with it

 

This should work , but i think the right one is ICS9LPR363DGLF.

 

Is that 2.5Ghz for benchmarking or do you use that constantly because I've been hesitant to go beyond 2.3Ghz.

I would think that you could OC the G72gx with less concern over the g51 because of the larger chassis. Still if I were to OC a G72gx I'd make sure to have a notebook cooler to be on the safe side.

 

benchmarking purposes only, i never use 2.53GHz cuz...i dont need to. i OC to 2.3GHz when i play games, that is sufficient enough for almost anything out there today...at least in my case.

you dont needa be hesistant tho, you can OC higher, if u BSOD, you know u are too high up (recomended to only go u by 0.05GHz increments, not like 2.0-->2.53 otherwise u will insta-BSOD). you can try and see what stable for you.

 

So, I guess I'll go to 2.3 to begin with.

 

I'm getting a little annoyed with Best Buy. The item has been backordered for a long time, and now it says out of stock. I can find no info on when they will be getting more of this item even though I ordered it weeks ago.
