    Default Another overclocking breakthrogh - ECS A75F-A Motherbaord

    In early July, AMD launched the latest architecture Llano APU.
    Since the launch, it has already been two and a half months. Initially, the only CPUs that can work with it were the relatively high-end A8-3850 and the A6-3650.
    The market prices of course were a bit higher.
    For chipsets, there are two options, the A75 and the A55, adopting the latest FM1pinout design. For now, it appears the price difference between the two is not very wide.
    The main advantage of the A75 is its support for the new SATA3 and USB 3.0 specifications. If you have sufficient budget, this is the better choice.



    The Llano APU was relaunched in early September together with three new CPUs, and compared with the previous two, the prices are lower
    With built-in GPUs, the A4-3400/A6-3500 are quite expensive compared with the A6-631, which has no GPU
    Currently, a total of five CPUs support the Llano APU architecture to offer more choices for the AMD FM1 platform
    To begin, windwithme has shared tests of the previous two Llano APUs, and we know that the biggest advantage of this platform lies in its significant 3D performance.

    Now the star of the show is the latest product from ECS, the ECS A75 motherboard
    The product is positioned as part of the Black Series, and the complete serial number is A75F-A, including the AMD A75 chipset
    The PCB is black, and the extension card slots are a complimentary gray or white


    Based on the ATX form factor, the size is 305mm x 220mm, a little smaller than standard ATX measurements
    The A75F-A is positioned as a high level A75 product, but the price is actually lower than many other brands

    The heat sink models used with the A75F-A are of a typical style with a design that increases the cooling area
    If you touch the heat sink, youíll find the actual surface temperature is quite low, but if you use a more attractive heat sink, itís certain to have a stronger selling point


    Test Platform
    CPU: AMD A8-3850
    MB: ECS A75F-A
    DRAM: CORSAIR CMZ8GX3M2A1866C9R
    VGA: AMD Radeon HD6550D
    HD: CORSAIR FORCEGT 120GB
    POWER: Thermaltake TR2 450W
    Cooler: Thermaltake BigTyp 14Pro
    OS: Windows7 Ultimate 64bit SP1


    CPU Default Performance Test
    CPU 100.0 X 29 => 2900.4MHz
    DDR3 1866.8 CL8 9-7-27 1T

    Hyper PI 32M X 4 => 23m 00.134s
    CPUMARK 99 => 418


    Nuclearus Multi Core => 12315
    Fritz Chess Benchmark => 14.86/7131


    CrystalMark 2004R3 => 200725


    CINEBENCH R11.5
    CPU => 3.46 pts
    CPU(Single Core) => 0.88 pts


    PCMark Vantage => 12700


    Windows Experience Index - CPU 7.3


    The A8-3850ís performance is little changed from the previous generation Phenom II, even when the CPU cache sizes of both L2 and L3 are slightly different.
    For those who need quad-core CPU performance, AMD offers better cost to performance,
    but regarding the single-thread performance of AMD CPUs, I still feel that in the future, AMD still has a lot of room to improve

    DRAM Bandwidth
    DDR3 1866.8 CL8 9-7-27 1T
    ADIA64 Memory Read - 9360 MB/s
    Sandra Memory Bandwidth - 15775 MB/s
    MaXXMEM Memory-Copy - 10680 MB/s


    This is where the Llano APU platform has made progress. The CPU default is adjustable up to DDR3 1866, which is a bit higher than the previous 1600 platform.
    While the bandwidth and their platform have made a bit more progress, compared with rivals such as the Sandy Bridge platform, the bandwidth seems to be lagging further behind ...
    DDR3 bandwidth is where AMD needs to improve in the future, and we hope that performance will improve with the launch of the Bulldozer

    Temperature Performance (room temperature about 26 degrees)
    Standby - 18


    CPU at Full Speed - 39
    LinX 0.6.4


    In a test of the AMD C&Q power-saving technology, in standby the CPU clock / voltage drops significantly, and for this reason the temperature falls quite a bit
    At this point, the obtained data was quite good, and even at full speed it was only 39 degrees.
    However, because the chips tested for temperature on each motherboard were different, actual temperatures may have been higher for some.
    But what is certain is that AMD used 32nm for the A8-3850, so there has been some progress with the temperature performance of the AMD platform

    Power Consumption
    Standby - 27W


    CPU Full Speed - 125W
    LinX 0.6.4


    Both the CPU and the GPU simultaneously at full speed - 153W
    With OCCT running, a test of the power supply


    In standby mode, because of the AMD C&Q power-saving technology, power consumption is reduced to only 27W
    With the Llano APU platform, the main power consumer is the CPU. At full speed, there is an increase of about 98W in CPU power consumption
    In addition, following our comparisons, we believe that the ECS had more outstanding power performance,
    and the A75F-A was about 10-20W lower than the previously used A75 platform

    3D Test
    Internal AMD Radeon HD6550D display driver
    3DMark Vantage => P4423


    StreetFighter IV Benchmark
    1920 X 1080 => 57.58 FPS


    FINAL FANTASY XIV
    1920 X 1080 => 947



    Built-in 3D performance is the biggest advantage of this platform, and the largest factor boosting the performance level is the DDR3 clock
    When combined with top of the line DDR3, taking the setting to 1866 will result in a significant 3D performance boost
    The above test data showed the internal 3D almost on a par with the nVIDIA GT430, and slightly better than the AMD Radeon HD5570
    Consumers who want to buy entry-level VGA should save their budget with this expenditure

    ECS brought the BIOS interface to the UEFI, and this new specification is what most of the motherboard brands have pursued in 2011

    Quite good support is provided with options for multiple languages


    M.I.B III Overclocking Page
    At the top are mainly the CPU multiplier, DDR3 clock and parameter settings
    In the middle are current parameters for the DRAM
    Below are the CPU FSB overclocking settings. This has a very significant impact on the Llano APU


    Voltage Range
    CPU Voltage +10 - +500 mV


    VDIMM Voltage -300~+600 mV
    NB Voltage +10~+360 mV


    DDR3 Frequency Options


    Built-in GPU that can share main memory capacity of 64M - 2GB


    Hardware Status
    Added Smart Fan speed control function


    Details about overclocking have been mentioned previously.
    When the Llano APU pulls the CPU to a higher clock, the SATA FSB will be pulled up at the same time
    For an extended time under 100MHz non-overclocked conditions, the stability of the SATA device may be uncertain
    This occurs with the entire A75/A55 series under overclocking conditions, and this is an inherent physical limitation in AMDís design
    For a wide range of users who want to overclock the CPU, we recommend that you wait for the launch of CPUs that are not locked.
    Increasing the multiplier is a better solution for overclocking

    With the AMD Llano APU, overclocking settings are a bit simpler
    Just pull up the CPU FSB and combine that with the appropriate voltage to achieve overclocking results
    Of course, youíll need to choose the right DRAM to effectively and simultaneously boost DDR3 and GPU performance
    Above are the overclocking settings from windwithme for the A75F-A for use as reference

    Overclocking Performance Test (SATA to IDE mode)
    CPU 122.0 X 29 => 3539.4MHz
    DDR3 2278.4 CL10 11-10-27 1T

    Hyper PI 32M X 4 => 19m 01.017s
    CPUMARK 99 => 510


    Nuclearus Multi Core => 15036

    Windows Experience Index - CPU 7.4


    When the A8-3850 overclocked from 2900MHz to 3540MHz, the CPU performance increase was about 20%
    Compared with the 32nm process CPU, overclocking added about 1.45V to the required voltage.
    This relationship between the clock and voltage did not result in significant progress.
    Although the performance of the A8-3850 CPU has been sufficient for most environments, consumers would like to see more progress with the new architecture

    DRAM Bandwidth
    DDR3 2278.4 CL10 11-10-27 1T
    ADIA64 Memory Read - 10826 MB/s
    Sandra Memory Bandwidth - 18915 MB/s
    MaXXMEM Memory-Copy - 13200 MB/s


    The Llano APU platform has made obvious progress with the DDR3 clock. In the past, the AM3 could only reach the upper limit of about 1800 to 2000 only
    This is the first time Iíve seen the AMD DDR3 overclocked to a clock of DDR3 2278, and better compatibility with the physical properties of DDR3 is very important
    Bandwidth has increased by about 16 percent, and after the DDR3 clock is pulled up sharply, one of the key areas that AMD needs to improve in the future is bandwidth efficiency

    Temperature Performance (room temperature about 26 degrees)
    Standby - 5


    CPU at Full Speed - 50
    LinX 0.6.4


    We have tried three A75 motherboard brands, and data showed standby temperatures of 5-18 degrees. This should be a result of C&Q power-saving technology, low voltage and low clock speed.
    The temperature of the ECS board at full speed was more than 10 degrees lower than that of the previous A75.
    The difference in temperature may be a result of Autumn coming on or the A75F-A temperature monitoring chip
    However, the above temperature data shows the 32nm process has reached a necessary level, and temperature performance is fairly good

    Power Consumption Test
    Standby - 30W


    CPU at Full Speed - 167W

    Full speed simultaneously for the CPU and GPU - 210W
    Test of the power supply with OCCT


    With C & Q power-saving technology enabled and the desktop in standby and when the CPU is operating at full speed, CPU power consumption increases by 137W or so, which is very high data
    The GPU increases by about 43W, and at such a high performance level for the GPU, power consumption is still within an acceptable range
    Although Llano APU is now fabricated with a 32nm process, the power performance still leaves room for improvement

    3D Test
    Internal AMD Radeon HD6550D display driver
    3DMark Vantage => P5451


    StreetFighter IV Benchmark
    1920 X 1080 => 70.21 FPS


    FINAL FANTASY XIV
    1920 X 1080 => 1171



    The Llano APUís internal performance mainly depends on level of the DDR3 clock When overclocking reaches DDR3 2278, there is an approximate 23 - 30% increase in 3D performance.
    In high-resolution environments, as long as the 3D game is not too demanding and not too many 3D effects are enabled, the system should be able to operate smoothly
    In the past, the gap in performance with entry-level VGA display was often as much as 5 to 10 times.
    In this yearís battle, the Llano APUís 3D performance has attained almost the same level as entry-level VGA.


    ECS A75F-A
    Advantages
    1. ECS has moved the BIOS to the UEFI interface, and many optional languages are available
    2. CPU and DDR3 overclocking ability is good, helping improve system performance
    3. PCI-E/PCI provides a sufficient and convenient number of expansions, and the A75 includes native SATA3 and USB 3.0 technology
    4. Three display output interfaces are provided that together with the A8/A6 CPU provide very dazzling 3D performance
    5. Heat dissipation is well implemented, and while the power is on heat sink and chipset temperature is not high

    Shortcomings
    1. The visibility of sales channels and service providers can be further enhanced
    2. When the CPU is overclocked to 107MHz or more only the IDE mode can be used. We hope that the BIOS can be revised

    When playing a Blu-ray movie, using the previously mentioned 1080P video playback, CPU usage rose as much as 10%
    The Intel internal HD2000/3000 GPU is of a comparable standard, and the new generations of the two brands can easily cope with 1080P

    The A75ís six internal SATA3 mechanisms are a significant difference compared with the native USB 3.0 technology of the A55
    Although the A75 is a bit more expensive than the A55, it still falls within mid-range market price points
    If you want a cheaper combination, of course the A55 will save some money, but if you want outstanding specifications, we suggest you consider budgeting a little more for the A75



    ECS has currently introduced three A75 motherboards, and this review is only for the A75F-A Black Series product with the ATX specification
    The A75F-A has a price of about NT$2900 or less, (equivalent to a retail price of about US$84.99) which is cheaper than some other A75 ATX brands
    Combining the UEFI interface, plenty of IO and ample PCI-E/PCI expansion slots as well as excellent overclocking features and more.
    The A75F-Aís cost to performance value is quite good, and we hope more value-added products will be introduced for consumers to choose from
    This article is windwithmeís third overclocking test of the A75, and each one provides detailed insight on performance, teaching methodology and the overclocking experience
    This is provided as detailed reference for consumers who are interested in buying new platforms using the AMD Llano APU. Thanks

    Does it support ECC RAM, does it have a non-flakey BIOS?

    Doubtful.
