On the base where its over the PCB (Left) is where there are 2x bars to screw the heatsink against the plastic casing and another 4x screw mounts around the core area for securing the heatsink against the core. The copper direct heatpipe has a (by the feel of it) a good quality thermal paste. One the other side of the PCB is where there will be strips for providing better mounting of the card.
This heatsink made a very good impression. Easily to remove and easily to clean, re-apply TIM and re-install, for those who wish to do so.
The card has a very clean and organized PCB, as I would expect from the TOP series.
There is a total of 8x Hynix H5GQ2H24AFA chips in total- 6 from within and 2 on the top of the PCB. There are 2x secondary fuse near the 2x 6pin PCIe cable to act as a Over Protection Circuit On the top part of the PCB which has 2x VRAM chips, you will see Asus’ signature SAP CAPs which is placed directly on the other side of the GPU core which is implemented to give higher efficiency, better capacitance which at the end of the day will benefit overclockers.
Although this card’s base clock itself is factory OCed by 157MHz more in comparison to the stock card’s base clock and GPU boost core clock of +144MHz more in comparison to the stock version of the GPU.
The section where the heatsink is installed has low RDS (ON) MOSFETs and PWM phase controller. I am not really too sure which one is it since its hard to make out what written on them, but Asus is known to use Richtek on some models. As usual, all the caps are made in Taiwan and are solid caps. Next to the chokes and solid capacitors, just before the PCIe 3.0 interface, there’s a DIGI+ controller that well uses them on their cards and motherboards. This card uses a 6+1 phase design, which the phase, MOSFET and solid cap for the VRAM is towards the left of the PCB.
The card uses GK104 core which was released on August 16th of last year. Its manufactured by TSMC and its built using 28nm technology. The card comes with 7 SMX clusters and packed with 1344 CUDA cores. There are 8 geometry units, 112 texture units and 24 ROP. The card is typically made to run 2GB GDDR5 1502MHz on 6 GHz data rate on the 192-bit bus interface. The GTX 660Ti supports 1x Dual Link DVI-I, DVI-D, HDMI and DisplayPort, so it supports upto 4 cards on the single card.
On reference/stock cards, it comes with a default base clock speed of 915MHz and with a boost of atleast 980MHz. Asus’s TOP version of this card base core clock speed of 1059 MHz and boost clock speed of upto 1137MHz. In comparison to the “DC2” versions which represent the stock version, other than the core clock preset and not having the “TOP Series” being mentioned on it its practically the same. You’re getting a factory overclocked card. That’s all there’s to it!
There are also LED indicator on the PCB, near the 2x 6 pin PCIe power connector which indicates if the power is supplied through the connectors or not. The LEDs are off when the system is not on, green when its getting the power and red when its not.
