Asus Strix R7 370 DirectCU II OC 4GB - User Review Introduction I’m baaaaack! Today I will be showing you the Asus Strix R7 370. The card is based on the now aging AMD Pitcarn architecture, originally featured in the Radeon HD 7870 and 7850 graphics cards. The tuned architecture has been able to hold itself well over the years, and AMD has worked hard to continue to develop and improve over the years, through refinements in its inner workings, but also through increased clock speeds thanks to the reduction of the node process to 28nm. Features are well in line with the current range of video cards on the market. The card itself features support for DirectX12, Mantle, OpenGL 4.5, OpenCL 2.0 and AMD’s GCN 1.0 Stream processors. Asus has created its own custom designed PCB layout and power delivery system featuring their 5-phase Alloy Super Power II VRM. Also a standout is the Strix DirectCU II cooling, with two (2) 8mm heat pipes transferring the heat away, and its 0dB fan system for silent operation when the GPU temperature is below 65°C. Specifications Features / Software AUTO-EXTREME TECHNOLOGY I mentioned this back in my GTX 960 Strix Review (found here : http://forums.overclockers.com.au/showthread.php?t=1188878 ), so those who read through, you can probably skip over this sections. Asus have taken things a little further with a complete ground-up design based around Auto-Extreme Technology. This is a first for the industry. The one thing I find that stands out with Asus products is the persistence in being market leaders in not only design and performance, but also its manufacturing process. Basically, Asus has developed an automated system for the production of its products and have removed the ‘human error’ factor and increased quality control of the products. In the process they have saved the workers from all those harsh gases released with the use of flux. Don’t look at this the wrong way, it’s a win-win for all. We, the end users can purchase a product of a very high quality standard, and for the workers in the factory, they no longer will have their lives shortened from breathing the deadly fumes every day. The final product is a nice neat looking card with fantastic quality control and a more reliable unit. All pluses in my books. Here is a video to explain the process better. https://www.youtube.com/watch?v=4gRpuurPsuc GPU Tweak II Software Included with all Asus Graphics cards is their own GPU Tweak software. I mentioned it in my previous review of the Asus GTX 960 Strix 2GB (Link - http://forums.overclockers.com.au/showthread.php?t=1188878) Initial setup was quick and simple. The layout is very easy to navigate and customise to suit what you want to see/use. The setup menu allows for keyboard shortcuts, and also to decide on start-up options. Another option is to unlock further settings past the limited clock, power, and memory settings for the more advanced users looking to push things further than most. Factory profiles are included for: Silent operation (a slightly under-clocked setting) Gaming (which is the default clock speeds) OC (a minor overclocked setting) Or User Profile, which can be setup and saved to suit yourself, or you can add extras to suit your own personal needs. Photos / Comments The product comes well packaged in a cardboard box, with sufficient packing around to ensure there is little chance for it to be damaged. Inside the box we have the graphics card itself, a Crossfire bridge, driver CD, manual and a nifty little Strix sticker. Moving onto the cooler, we can see from the top that Asus has a nice Owl theme going, with the menacing eyes looking back at you. The cooler is setup to only turn on when the card reaches the pre-set temperature. The fans measure 75mm. 2 x 8mm copper heat pipes transfer the heat from the core to the aluminium fin array. There is also what appears to be a solid finned heat sink to cover and spread the heat of the VRM componentry. The power delivery for the card is supplied through a single 6-pin connector, located on the rear edge. Asus have used their Super Alloy Power II component for the power delivery, featuring a 5-phase setup for cleaner power supply and longevity. Above the 6-pin power connector, there are red indicator LED’s which change to green when the power is connected correctly. Nice little touch there. It can also aid when troubleshooting, should there be a problem. The connector is also rotated 180° from the usual, with a little notch in the PCB. This makes removal of the power a lot easier than other cards. Asus recommends a minimum of 500W power supply with a minimum of 24 Amps on the 12V rail. On the backside of the card, we can see how physically short the PCB actually is. The heatsink radiator and fans from the DirectCU II cooler actually protrude past the end of the card. My guess is to aid with the airflow through the cooler, which is quite effective. Overall, the card measures 21.5cm in length and 12.5cm in width. The card can support up to six (6) monitors through the rear connections using AMD Eyefinity. It includes four (4) different connectors: 1 x HDMI, 2x DVI and 1 x Display Port.
