Not happy buying memory from him. I am expecting that i will get a memory with mtec chips but he said that mtec is the brand of the memory not the chips (is there such a brand anyway? I can't see the name mtec brand in the memory module). It won't run cas 2 and had to live with slower memory for my pc. I know a lot of people knows what mtec chip is when one tpc member is looking for one. I really feel very bad. He looks like a nice guy base on so many positive feedback but i think i will let him decide if he wants to redeem himself.
