Most people love their brand new Galaxy devices from Samsung and Captivate owners are not the exception. However, being in the tradition that is XDA, everything can be better. This pushed XDA member blackjackboy as well as other devs including AJerman, to created a new kernel for these devices that would make things run better on the Captivate. A nice feature of this new kernel is that it allows overclocking of the 1 GHz Hummingbird processor to 1.2 GHz. For this, you will need to download SetCPU, which can be found on the forums as well as the market.
The dev also mentioned that this is not the full limit of the Hummingbird, as it can theoretically clock at 1.6 GHz and be stable. It may, in theory, be able to go past this number as well.
OK guys, thanks to AJerman and many others who have posted in this thread, we have had success in compiling, loading and running a bug free kernel. The wakeup lag is there, but is highly reduced. Also, if someone could figure out how to compile a boot.img so that we can simply flash the kernel through recovery (I have no idea how), we would really be grateful, for all of us with either Linux or Mac. Anyway, here is the link, flash it through Odin3 . Bug reports are welcome, as are logcats. Please download SetCPU from the market, or for free from an xda thread (I forgot where it is, I think it’s in the G1 section). Set to OnDemand to reduce wakeup, set lowest possible value for min, and highest for max (1.2 GHz). Of course, you can also use profiles if you are an advanced SetCPU user. Thanks for reading, here we go!
Overclocking a device sometimes can be dangerous as it affects the hardware directly. Proceed at your own discretion.___________________
