Q: 2. will this work on HP Desktop ENVY 700-074 ?

A: The OWC 32GB DDR3 1600 MHz SO-DIMM Memory Upgrade Kit (4 x 8GB) will not work in an HP Desktop.

Also, they are not the correct form factor.

Q: 3. Can the 2 16GB modules be installed on an early 2009 24 inch iMac ?

Q: 4. I have 8 gigs RAM stock (4 *2). Can I add one 8 gig to make 16 or do I need to replace the 4s with 2 8s to make,16?

A: Either go with two more 4's to make 16 or 2 8's (leave the 2 4's you have in) for a total of 24. This ram needs to be installed in pairs.

Q: 5. Can I install this in my MacBook Pro Mid 2010?Processor: 2.4 GHz Intel Core 2 DuoMemory: 4 GB 1067 MHz DDR3Graphics: NVIDIA GeForce 320M 256 MB

A: This kit is for an iMac with 4 memory slots. I would need to know the computer's serial number to point you to the correct memory modules.

Q: 6. Why is this product/package prized so high or so differently? Say, with other OCW 32GB package? I'm talking about the OWC / Other World Computing 32GB DDR3 1867 MHz SO-DIMM Memory Kit (2 x 16GB, Late 2015 iMac Retina 5K) which is prized at $508, while the other package is just around $200.

A: What is the item code for the other 32GB kit that you are comparing this one to?

Q: 7. Can this be used to upgrade the memory on an 5k imac late 2015?

A: I couldn't get the OWC 16GB DIMMs to work reliably in a 64GB (4x16G) nor in a 32GB (2x16G) configuration in my late 2015 5k 27 iMac 17,1, so I had to return them -- system would panic and reboot in less than a minute while running BMD Disk Speed test. After reverting back to Apple-supplied 2x4GB configuration, everything was stable again. Next I'm trying a 4x8GB config using Crucial (Micron) DIMMs, which are also much less expensive.

Q: 8. dose it work with the Intel DP67BA?
