about overlocking gpus in laptops

my ati catalyst control center doesnt seem to have the overclocking feature and amd does not provide drivers for laptop graphics.is there any other way to overclock my gpuabout overlocking gpus in laptops
If you're thinking about overclocking a laptop GPU, I would think twice. Laptops are already designed with limited cooling, and then that cooling is already designed to be pushed to the max. You're not going to get far before your temps get into the danger zone, and even then you won't have clocked far enough to make a difference.about overlocking gpus in laptops
Do not overclock your gpu in your laptop. Laptop cooling is already insufficient for the most part and it's really not worth the extra 4-5 fps if you end up frying your system.
[QUOTE=''onfire23'']my ati catalyst control center doesnt seem to have the overclocking feature and amd does not provide drivers for laptop graphics.is there any other way to overclock my gpu[/QUOTE]Kinda depends on how partial u are to ur Lappy. I have an old Compaq Laptop with an ATI Gpu as well. I was able to overclock it mildly and I didnt seem to have any problems. Sure it got hot - but ah well, like I said - its an older laptop. If I had anything new I wouldnt dream of attempting it. Of course, If I had a newer laptop I'd be sure to buy a decent one enough to where I didnt have to worry about OC'ng it in the first place.X~
i installed ati traytool,ati tool,riva tuner and found that non of them were able to adjust my gpu clock.maybe sony made this laptop overclock proof or is there any othere way.by the way my temps(gpu)are mostly from50-60's.my laptop actually runs pretty cool which made me to think about oc'ing.ati's website says that there is no driver support for ati mobility radeon products and they should be downloaded from the notebook manufacturer site.but is it ok if i download the latest version of theCCC only without the display driver(which i already downloaded from the sony site).and the main question is why is mY CCC not displaying options for overclocking.has sony intentionally made them unavailable and will installing the new CCC HELP.i know it is a lot of questions but someone help me

ATI only unlocks driver level overclocking for their gaming/enthusiast parts. For example Radeon HD 4800, Radeon HD 4700, and Radeon HD 4600 level cards. When you start getting into the 4500 and 4300 series of cards that feature is no longer available because these are entry-level and budget minded cards where gaming isn't a top priority, low power consumption and stability are. It's not a problem with CCC, it's by design. CCC identifies what chip you have installed and gives you access to overdrive accordingly.
hey i have an ati mobility radeon hd 4650 and the ati overdrive feature is locked.but you are saying 4600 series cards are unlocked

Well like I said that's usually how it goes. They might lock it for all Mobility Radeons for all I know. What I do know is that if they don't want to officially support overclocking your chip then the overdrive tab is absent by design.
ok, thanks for the info.i had thought that it was a problem only with my card
I've overclocked my laptop's gpus before. I really don't recommend it, you have to be pretty aware of what you're doing in a laptop. I found out through overclocking that my gpu was actually one of those defects ffrom Nvidia, I tried seeing what would happen on a normal OC, like +30mhz core... random slowdowns, gpu 120c... I was like lol, then I just took them off, still 120c. Dell did a 2 day rma, very nice. But on my other Asus laptop I actually got +60mjhz out of the core, and overclocked the cpu from 2.4 ghz to 2.6. Not too much point in overclocking laptops, maybe only if you bought a lower end cpu and want it to run at the specs of the higher clocked one.
I don't recommend you take any of these posts seriously.



Overclocking your laptop GPU is like overclocking anything else, if the temps are fine, and you get no artifacts, then there is nothing to worry about. I had a Dell inspiron for over a year and a half with an 8600M GT. The stock GPU clock was 475 mhz, but there was no issue clocking it to 650mhz. It was so stable that i flashed the gpu bios with that speed as the default speed. I know this sounds pretty far-out, but search google, its definitely doable. As for overclocking with the ATI mobility GPU's. My current laptop has a mobility 3650 (overclocks from 450mhz to 675 mhz btw). All ati drivers since 8.7 have overclocking locked for everything except for the ATI control panel, and even that locks it for mobility GPU's. The only way to get around this is to run 8.7 or older. If you decide to do so, i recommend finding the AMD GPU clock tool (ver 9.8), it will let you overclock and show you temps. Idealy i would like to be able to make that speed the default in the GPU bios so that i can run the newest drivers, but there is currently no software available that allows flashing a mobility 3650 bios.
