Benchmarks

The ASRock M3A785GMH/128M supports the ACC feature. Instead of explicitly naming the hidden feature as a patch, it just labels it as the normal ACC feature just like in the any AM3 boards. When the ACC is enabled, you can select per core or all cores for voltage boost. Once that is done, the hidden core on the Phenom II X3 710 appears.

In our test, we used the driver provided in the package. This driver seems to be more mature than the previous one used on the ASUS and Gigabyte we reviewed earlier. The version number is newer too. The driver version information is shown below.

The first is the default timing with GPU running at 500MHz and side port memory at 667 MHz (DDR3-1333). The second test is with GPU overclocked to 900MHz with voltage bumped slightly to the North bridge.The third test is with the the 4th core enabled and in the fourth test, we increase the sideport memory to  790MHz or DDR3-1580.

We have seen the Gigabyte's microATX DDR2 version of the board. So, we are able to compare it with the performance of a DDR3 board.

On the board, we ran two piece of three of the Kingston HyperX memory at C7-7-7-20-1T. This is in contrast to DDR2-1066 running at CAS 5-7-7-24-2T. From the chart, we can easily see that with DDR3, the memory bandwidth is slightly better at 11.8-12GB/s. On a DDR2 board, it only scores around 11.6GB/s

Arithmetic Processor test

With 4 core enabled, the increase in performance is noticeable. In Whetstone, the difference is 33% while Dhrystone gives a difference of 36%. As this is more of a test of the processor, the differences between a DDR3 vs a DDR2 board is very minute. The scores are almost identical.

Multimedia Processor test

The improvement in Multimedia test is quite noticeable too. In Int X4 test, the difference is 33% while in Float x8, the difference is 34%. When compared to a DDR3 AMD 785G board, the results didn't differ too much too.
