Test Setup

Test System
CPU:	Intel E6300 Conroe 1.8 GHz, 2 MB Cache
Motherboard:	ASUS P5B Deluxe BIOS 1004
Video Card:	ATI Radeon X850 Pro PCI-E
Harddisk:	Maxtor DiamondMax 160GB
Power Supply:	OCZ GameXStream 700W
Software:	Windows XP SP2, Catalyst 6.9

Since we are testing this memory on the ASUS P5B we will use a Write to Precharge Delay setting of 13 as suggested by A-DATA.

Performance

As always, the first test is how the memory performs at the standard frequency of 400 MHz, with standard voltage of 1.8V. The second and third tests are at 400 MHz too, but with different timings of CL5 and CL3. Here you can easily see how much difference changing the timings makes.

Next we tried how fast we could get this memory to run at CL5 with voltages of 1.8V, 2.05V, 2.25V and 2.35V. 1136 MHz at 2.35V is quite impressive.

The next four tests show how well the memory performs at standard CL4 timings over the same wide range of voltages. Even at the standard voltage of 1.80V this memory can run 800 MHz DDR2 which is important if you plan on running on a cheaper motherboard that supports no memory voltage control.

What if you don't need extremely high MHz, but want good timings? We tested to see how far the timings could be tightened. The fastest setting we could reach was 3-2-2-4 which is the fastest setting that is available by the chipset. However, to get acceptable clocks out of the memory at CL3 you need to increase the voltage quite a bit.
