Video card ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING) on AMD Radeon R7 370: review and testing 

Along with the flagship video cards AMD Radeon R9 Fury X and AMD Radeon R9 Fury, as well as high-level models of the series AMD Radeon R9 300, AMD has updated the budget segment of own product, which along with last year's series of AMD Radeon R7 200 received a new name - AMD Radeon R7 300. One of the innovations is the graphics card AMD Radeon R7 370, which will be offered for a suggested price of $ 149 for the modifications to the reference design.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

It received a renamed and graphics core slightly modified from last year's adapter AMD Radeon R7 265, which now has the name of AMD Trinidad PRO instead of AMD Curacao PRO. In turn, this has already been renamed GPU AMD Pitcairn PRO with old one AMD Radeon HD 7850.

At the same time it doesn’t have any significant structural changes: the chip also includes 1024 stream processors, 64 texture units and 32 units of rasterization. As for the video memory subsystem, two versions of the video card were announced: 2 or 4 GB and effective frequency 5600 MHz.

Like all video cards in series ASUS STRIX, the novelty has received quite a large list of changes compared to the reference specifications. So, in addition to the original PCB, proprietary cooling system and improved element base, there is a factory overclocking. The graphics core is clocked at 1050 MHz (increase of 7% compared to the recommended 975 MHz). Video memory operating at the reference effective frequency of 5600 MHz.

Package and content 

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

Graphics card ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING) comes in a fairly large cardboard box and decorated with original and stylish line of the graphic printing with logo ASUS STRIX. In addition to the names of the manufacturer and model of the device here you can find information about the use of its proprietary cooling system DirectCU II with technology 0dB FAN, which provides 30% lower temperature compared to the reference cooler and in passive mode at low loads.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

The reverse side of the box is traditionally reserved for the slightly more detailed description of the advantages of new item. Also, there is a schematic diagram of the interface panel, and the mention of the features of proprietary utility GPU Tweak II with the functions of the online Online Streaming.

As for the benefits, they include:

  • DirectCU II - proprietary cooling system which compares favorably with the direct contact of heat pipes with a graphics core, 220% greater area of heat dissipation and 40% higher thermal conductivity that allows a 30% reduction in the temperature and decreases three times the noise level compared to reference cooler. 
  • ASUS Auto Extreme with Super Alloy Power II - model ASUS STRIX-R9390-DC3OC-8GD5-GAMING is one of the world's first graphics card built in a fully automated line, which guarantees consistently high quality and ensures the rejection of aggressive chemicals in the production process. In addition, it is based on using high-quality electronic components (Super Alloy Power II), allowing further improves the reliability of the new item.
  • 0db FAN provides silent operation of video at low loads.

Design and circuitry 

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

Model ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING) is realized on a compact black PCB. Used electronic components correspond to the branded concept Super Alloy Power II and include only high-quality components: solid and tantalum-polymer capacitors, advanced MOSFETs and ferrite core chokes. This increases the stability and reliability of the graphics in general, and prolongs its lifetime.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

Power of new product is made according to 4+1-phase scheme where four phases are responsible for the power of the graphics core, and one is designed for video memory subsystem.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

Chip uP1608TK is applied as a digital PWM controller of power subsystem.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

In order to power the graphics card there is a PCI Express x16 slot and one 6-pin PCIe, located on the side of the board. Note that the cooler doesn’t complicate the disconnection or connection of the cable PCIe.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

To implement the technology AMD CrossFireX on ASUS STRIX R7 370 a single connector for the corresponding bridge is used. It allows you to combine two video accelerators for the joint calculation of graphical effects.

The reverse side of the printed circuit board contains mounting screws of cooling system and some electrical components.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

The base of ASUS STRIX-R7370-DC2OC-4GD5-GAMING is a graphics chip AMD Trinidad PRO, which is determined by the utility GPU-Z 0.8.5 as the AMD Pitcairn. It is produced by the norms of 28-nm manufacturing process and consists of the 1024 unified shader pipelines, 32 ROP units and 64 texture units. The GPU operating frequency was increased to 1050 MHz with respect to the recommended 975 MHz.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

Memory of model ASUS STRIX R7 370 (total 4 GB) is realized due to the use of 8 chips SK hynix H5GC4H24AJR-T2C with capacity 4 GB each, which run on the recommended effective frequency of 5600 MHz. Communication between the graphics processor and memory is realized through 256-bit bus, which is capable of carrying 179.2 GB of information per second.

Cooling system 

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

The video card including installed cooling system ASUS DirectCU II takes up two expansion slots and has a total length of 214 mm according to the official website (226 mm as measured in our lab).

The cooler consists of a compact radiator with 38 longitudinally spaced aluminum plates, and two 75 mm axial flow fans mounted on the plastic case.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

The fans are produced by company EVERFLOW and are labeled as «T128010SH». Rated voltage of operation is 12 V, and the current is 0.25 A, which gives the final output of 3 W.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

The uniform distribution of heat over the whole area of the radiator is provided by two copper heat pipes with diameter of 8 mm. Fins and heat pipes are covered with a layer of nickel, which is designed to reduce the drop in the efficiency of cooling system during the operation, due to the oxidation of metals. ASUS DirectCU cooler use scheme of direct contact of heat pipes to the surface of the GPU through a small layer of thermal paste to accelerate removal of excess heat.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

To cool the power elements of the power subsystem there is a separate low-profile heatsink with thermal interface. But memory chips don’t have any additional cooling.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

In case of the automatic speed control of the fan blades and under maximum load, the graphics core is heated to 75°C, and cooler works while 43% of its maximum capacity. Noise subjectively was quiet and comfortable for everyday use.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

Under the maximum speed of fan blades rotation the GPU temperature dropped to 59°C. This noise exceeded the average level, but in a closed PC case it did not stand out too much compared to other components.

ASUS STRIX R7 370 (STRIX-R7370-DC2OC-4GD5-GAMING)

In case of load absence the operating frequencies of the graphics core and memory were automatically reduced, allowing them to reduce power consumption and heat. In this mode, the GPU temperature did not exceed 39°C because the fans stopped to rotate and cooling system operates in a completely passive mode. Here the above-mentioned technology 0dB FAN is activated, providing silent operation of video at low loads.
