Upgrade the memory in your 2013 Mac Pro (MacPro6,1) using the 64GB DDR3 1866 MHz RDIMM Memory Kit from OWC / Other World Computing. This memory kit features a total capacity of 64GB, which is made up of four 16GB modules. It also has a clock speed of 1866 MHz, a bus speed of PC3-14900, and a 240-pin RDIMM form factor. It operates using 1.5V, has a CAS Latency of CL=13, a module bandwidth of 14.9 GB/s, a component configuration of 2048M x 72, is registered, and is equipped with ECC technology. Registered memory places less electrical loads on the memory controller and allows single systems to remain stable with more memory modules than they would have otherwise. By offering ECC (Error Checking and Correcting) technology, this RAM will help your workstation encounter fewer errors that can corrupt data sets and introduce system issues. Additionally, this memory module is compatible with Apple Specified Thermal Sensor, which ensures that the RAM maintains a safe thermal operating range.

Related Questions and Answers

Q: 1. Do these have heat spreaders attached?

A: The RAM chips in this kit have heat sinks attached to them.

Q: 2. Will this 64Gb RAM upgrade speed up a 2013 Mac Pro (currently with 32Gb RAM) running heavy video / 4K content and applications?

A: That depends. Are you running out of memory? If you still have 50% of memory available while you are running the app then you probably won't notice a difference. It might be possible you need a processor upgrade instead. Find out why it is running slow first, then upgrade the correct part. But, yes this will give you 32GB more RAM if you install the upgrade, and theoretically improve performance.

Q: 3. I have a RAM with error among 4x32GB. Can I replace just one?

A: They should be replaced in pairs.

Q: 4. Will this RAM work on my Mac Pro (early 2009) 2x2.6GHz Quad-Core Intel Xenon?

A: Yes it certainly will. I have a new Mac Pro but the old version (early 2009) is still working with this memory upgrade.

Q: 5. Is this compatible with Mac Pro mid 2012 with 3 1066 2GB installed and one empty slot. I want to raise the RAM to 32GB. If this does not work what RAM do you reccomend?

A: This memory will not work in a Mac Pro. This is memory for an iMac or Macbook Pro. You need the OWC1333D3X9M032. However, this memory will require you to remove the existing Apple memory.

Q: 6. Will these Mac kits work in a PC desktop with the same number of pins?

A: As these chips contain specific features for Apple compatibility, such as Apple Specified Thermal Sensor. This may or may not prevent the chip from working in a PC.

Q: 7. Will this work on a late 2007 macbook pro?

A: I don't think so. What you need is: DDR2-667 SODIMM https://a href= http://www.bhphotovideo.com/c/product/1213048-REG/owc_other_world_computing_owc5300ddr2s4gp_4gb_memory_upgrade_kit.html target= _blank www.bhphotovideo.com/c/product/1213048-REG/owc_other_world_computing_owc5300ddr2s4gp_4gb_memory_upgrade_kit.html/a

Q: 8. Will this work in a Asus M5A78L-M/USB3 Motherboard?

A: From the limited specifications I can find on that motherboard, I believe the memory will work, but I cannot make any guarantee, as we have not tested this RAM with that motherboard.

Q: 9. What's difference between the Patriot Viper 3 16GB (2 x 8GB) 240-Pin PC RAM DDR3 1866 (PC3 15000) Desktop Memory Model PV316G186C0K and this one?

A: The Patriot Viper 3 Black Mamba 16GB DDR3 1866 MHz CL10 UDIMM Memory Kit (2 x 8GB) is the same as B&H# PAVDD316186B MFR #PV316G186C0K.

Q: 10. Can this memory work in an acer aspire7741 ? (windows)

A: It appears that your Aspire requires 1600MHz memory, this would not be appropriate.You would need OWC1600DDR3S08S.
