Internals and Documentation
Since the G-Sync module and PCB are already, well, 'exposed', here are a few shots of the externals:
This side of the PCB holds the G-Sync module itself, along with the necessary logic to interface it with the ASUS LCD panel controls (power, brightness, etc).
The other side takes care of all of the power handling circuitry. Most of the work is done by an external power adapter, so things are sparse here.
The back of the PCB is mostly empty, save some leftover power handling components.
If you guys know me, you know I *have* to take apart *something* for a review. The G-Sync module seemed a fitting victim:
On the front of the PCB we have the logic and memory required to perform the G-Sync goodness:
I was sort of expecting a spiffy G-Sync logo here, but I'll take Altera instead. The back story here is that NVIDIA chose to go with a more expensive FPGA chip for this first round of G-Sync hardware, reason being is that it is faster to get a product to market in this manner. This is typical for first run hardware, and purpose-built ASICs would logically follow in future generations of G-Sync hardware.
The rear of the PCB contains minimal power / filtering circuitry, in addition to firmware.
I must say this is the best documentation I've ever seen for anything DIY – and it is absolutely necessary as this is not the sort of mod that most folks will be familiar with. Lets dive in and install this puppy!
