IC chipset test ICchipsets we utilizes are only top grade from original brands, like HY,Samsung, Elpida, etc. When new IC chipsets are received, we randomlychose samples for test, approximately 10% to 20% ratio, on profestionaltest software---RST. Only if the samples are all withouth problem, thisbatch of ICs can be sent to the next test; 2. SPD infomration test of the Module Tocheck whether the SPD information is correct, we use two professionalsoftwares, CPU-Z and Sisoft Sandra 2007, to separately test the module.During this procedure, we subject to internationl stardard AQL to picksamples. 3. Compatibility test of the Module Samples which arepicked according to AQL standard will be installed on more than 200 mainstream brands of motherboards, like Asus, Intel, etc. 4. Stability test Picksamples according to AQL standard. Only after continous work WITHOUTCRASH for 48hours individually at 70 degrees centigrade and -10degrees centigrade under big software like 3DMARKS, big games, etc, theModule can be sent out of the factory.
