Quality control

1. IC chipset test
IC chipsets we utilizes are only top grade from original brands, like HY, Samsung, Elpida, etc. When new IC chipsets are received, we randomly chose samples for test, approximately 10% to 20% ratio, on profestional test software---RST. Only if the samples are all withouth problem, this batch of ICs can be sent to the next test;
2. SPD infomration test of the Module
To check whether the SPD information is correct, we use two professional softwares, CPU-Z and Sisoft Sandra 2007, to separately test the module. During this procedure, we subject to internationl stardard AQL to pick samples.
3. Compatibility test of the Module
Samples which are picked according to AQL standard will be installed on more than 200  mainstream brands of motherboards, like Asus, Intel, etc.
4. Stability test
Pick samples according to AQL standard. Only after continous work WITHOUT CRASH for 48hours individually  at 70 degrees centigrade and -10 degrees centigrade under big software like 3DMARKS, big games, etc, the Module can be sent out of the factory.
