Summary: Bought these to upgrade some office computers HP. Bad buy.. and I bought 2... found out that HP limited the CPU identifiers in the BIOS on most of their computer to the one that comes from factory. In that way you can not upgrade HP computers with a new CPU.. Bad practice HP.. Will buy other computer brands in the next cycle, small business owner.. No wonder HP is a dying company.
Summary: Seller said this would work like brand new. Had this one and was buying it for a previous build I had and then it sent my computer into a boot loop and died all together. Seller refuses refund.
