ECS A890GXM-A2 Review

Bus frequency overclocking
For
the following tests we started with the memory set to 1066 MHz with 8-8-8-24
timings at 1.65 Volt. To determine wether the system was stable or not we were
using the CPU test of Futuremarks 3DMark 06. To enter the different setting we
use both the BIOS as well as eOC from ECS (more info on the review's Thread in
the forum).

Even with higher northbridge, Southbridge and memory voltages and further decreasing the NB and memory ratio, the board didn't pass the 310MHz. But never the less 310 MHz is an excellent result.
CPU Overclocking
For this test we kept
the previous settings:
- NBFreq : 7 x 200 MHz
- HTFreq : 2 x 200 Mhz
- MemoryFreq : 2.66 x 200 Mhz @ 8-8-8-24, 1.68 V
- CPUFreq : 16 x 200 Mhz
In this test we also used eOC as well as the BIOS to do the overclocking.
| CPU OverClocking | CPU Freq | Percent |
| DFI LanParty DK 790FXB-M3H5 | 4'350 | 107.41 % |
| ECS A890GXM-A2 | 4'275 | 105.55 % |
| ASUS M4A78-HTPC (DDR2) | 4'050 | 100.00 % |
| Higher is better | ||
The highest frequency which we reached stably was 4'275 MHz. Therefore we needed to provide the CPU with 1.5 Volt. To obtain overclocking results which are as comparable as possible we set northbridge and the HT multiplyer to 10. The memory frequency we tried to keep as close to 800 MHz as possible.
