The ASUS GTX780 Direct CU II OC arrives in the striking ‘monster claw' box. An image of the Direct CU II cooler is showcased on the left of the box.
The GPU ships underneath a peripherals box, protected between foam. ASUS include an extra length SLI cable, a software disc, power converter cable and a manual. We do advise people to get the latest driver from the Nvidia website.
The ASUS GTX780 Direct CU II cooler is made from metal, and the back of the PCB is covered with a back plate to offer protection and to aid with cooling efficiency. It is a dual slot cooler.
If you are paying attention you will notice that the fans are both different. The blades on the left fan are designed at a different angle to help pull the air across the heatsink from the other fan and out the rear of the case, improving cooling efficiency and reducing noise.
The ASUS GTX780 Direct CU II OC has two DVI ports, (DVI-I and DVI-D) and an HDMI and DisplayPort connector.
The GTX780 is SLi capable in a 2 or 3 way configuration. This particular model from ASUS takes power from a single 8 pin and 6 pin connector.
ASUS have included a backplate on the PCB and there is also a cooling heatsink dedicated to the VRM's. They have incorporated high grade SAMSUNG GDDR5 on this card. The main cooler itself is unusual in that it is a direct contact design and has a huge heatpipe on one side and four thick heatpipes on the other side transferring the heat to different parts of the heatsink.
It is a very heavy heatsink and extremely well constructed.
The ASUS GTX780 Direct CU II OC has received a core clock boost from 863mhz to 889mhz. The Boost speed is set at 941mhz and the memory speed 1,502mhz (6Gbps effective). The GK110 core is built on the 28 nm process and this card has 48 ROPS, 192 TMU's and 2304 CUDA cores. The 3GB of GDDR5 memory is connected via a fat 384 bit memory interface.
Love this card, but its still a bit rich for my blood. are they doing this with the GTX 770?
thats a crazy OC for such a high end board.
I love the nvidia boards in this generation, but they are all so expensive. im still looking at getting a 760 as I only game at 1080p. think its enough. waiting on the ti version if there is one coming out soon
Great review, but for under half the price I would recommend getting a GTX 760. I got one last week and it’s a great card for around the £210 mark.
Great review.
I wish you guys would actually find a truly STABLE overclock. Just like everyone else you get a clock speed that’s stable for a 10-minute benchmark, but not for real-world games. It’s misleading and people who buy and overclock the card are disappointed to find that truly stable clocks are much lower than those in reviews. I haven’t seen anyone across all GTX 780 threads get a truly stable core clock above 1040MHz, even for the water cooled custom ones. You should really run intensive games for 3-5 hours to get your overclocking results, and you’ll see they are nowhere near as good as you thought.
I played a few games on it for hours and it was stable at 1040mhz (no artifacting on memory or core and no hard locks etc). Its only misleading if people think that every graphics card in that particular range will hit those speeds, but they don’t as we mention in many reviews and I hope our audience know from 3 years of reviews here that every card can deliver VERY different results. Same as when you are overclocking processors.
We attempt to make everything as transparent as possible.
I bought one of these and the card is stable at 1204mhz with a 200mhz boost on the memory (couldnt get the memory overclock they achieved to become stable) but this clock speed was playable through the first half of crysis 3 (got tired of the game after a few hours) Then played borderlands 2 for a few more hourse. I finished off my testing with some fur-mark burn in tests to insure stability (2 hour burn in test). My room did get quite a bit warmer during this gaming period, but my window was open and outside was cold. The temps held steady at 73-76 Celsius for most of the duration of testing with the max temp being 77 degrees Celsius.
