Overclocking

Overclocking with the ECS A75F-A was fairly simple. With a limited BIOS that does not feature any secondary timings, we knew that dropping the base memory divider was needed, so we did so quickly, and then scaled up the reference CPU bus. We had to drop the multiplier a fair bit as well, as we found that although the BIOS indicates it's capable of giving +200 mV to the CPU, we only noticed a maximum of 75 mV being provided, which did affect clock scaling, leaving our final result below what the Gigabyte GA-A75-UD4H was capable of. At the same time, however, the ECS board did allow us to scale our CAS 6 memory all the way up to 1786 MHz, a very respectable showing, for sure. There's a lot of tweaking possible, but as we expect from ECS, the BIOS does limit overclocking, but at least the ECS A75F-A makes no claims as to being a top overclocker, so these results are perfectly fine in our book; good scaling, but not record-setting.

Overclocked Performance Summary

wPrime does seem to scale pretty well on the AMD A75 platform. The result here shows efficiency at stock is pretty high, something we like to see.


Limit memory timings did limit SuperPi performance scaling a bit, but we still saw significant gains over stock.


Cinebench is like the other overclocking results; good and reliable, but not jaw dropping.


F1 2010, however, did make our jaws drop. With gains of near 14 FPS over stock, we were pleasantly surprised to see one of the very best F1 2010 overclock results, ever!
