Need refund
Delivery was on time. Parcel was not damaged. Memory for PC isn't working properly. Check with program MemTest86 errors wasn't found bad blocks. Operating system working not properly spontaneously reboots and freeze. i have two modules of memory 2Gb and insert the third module 3Gb and i see following symptoms which i have described above. If compare with memory which I bought for laptop this memory works not very well. I will try to check on another computer I think the result will be the same. i am upset quality is not very good for memory modules.
