OFFTEK 4GB Replacement RAM Memory for HP-Compaq HP Pro 3000 (Small Form Factor) (DDR3-10600 - Non-ECC) Desktop Memory

Even though this memory was listed as working for a HP Pro 3000, it dosent. The system will only handle a max of 2 Gig chips in each slot. I was hoping this would work and have the OS manage the memory with the 64 bit operating system. But it dosent. The company was great and took this back no questions asked - recommend them. Just stay away from the 4 Gig chip for these HP systems.
