2 pads of CPU are damaged. CPU boots system, but sometimes system crashes. When I try with the same CPU type, from another store, system is stable.
Delivered in 2 weeks. The package includes a packet of good thermal compound (I got the compound of gray color). The CPU had some old thermal compound (bright white color) on the back side but I have cleaned it and had no problem after that. Works great on Gigabyte GA-H61M-S1 (rev 2.0) motherboard and requires at least the "F5" version of BIOS. I recommend this seller!
