Pc3 12800e memory install#
So if you install two modules, PC3-12800 and PC3-10600, the memory bank will only run at 10600 MHz. It's middling OK if you realize that the bank that the modules are installed in will default to the module with the lower clock frequency. HP has deep pockets, their reputation and Engineering technicians and Engineers performing those QA tests. HP tests the combination of very specific RAM modules in a laboratory and does QA stress tests to ensure they will work. It increases the risk of a no-boot scenario. Mixing of memory frequencies and memory modules densities , has been found to not be a good practice to follow.
Pc3 12800e memory manual#
Hi again,I have browsed HP service manual for this model and it appear that mixing memory is possible provided the total memory installed in channel A is equal to the total memory installed in Channel B and that the PC will work in high performing dual channel mode, if this is the case then my mixing of memory should be no problem,but no information about the support to use ram of PC3-12800, I am not sure if this memory when installed it will work at different clock of lower speed,though it works but may not be the correct speed,please let me know. That way you are not risking having no-boot scenarios and possibly corrupting data on your hard wrote:
Let the memory manufacturers test configurations in their labs. Mix and matching module bandwiths, capacities and brands is not a good practice.
Pc3 12800e memory upgrade#
The best way to upgrade and have it work as expected the very first power on is to always use absolutely identical and guaranteed compatible memory modules. The link you send me to crucial ram shows that PC3-12800 can be used for this model? They test the configuration and stake their company reputation on their guaranteed compatible memory modules. They have tested their memory with the laptop.Ĭan I mix 4GB PC3-12800 and 4Gb PC3-10600 in this model? No. Thank you for the help,Kudos left to thank you.Ĭan I use PC3-1288 RAM in this model or had to be PC3-10600 as stated in the manual? If Crucial says DDR3 PC3-12800 then you can believe it. The upgrade to 16 GB is pretty inexpensive considering what it brings to the table. See the Crucial compatible modules at the following web document. It is akin to rolling the dice.įour identical guaranteed compatible memory modules is the best way to go. 4 GB and 2GB modules) on a motherboard is a poor practice and may disappoint you by corrupting the data on your hard disk someday.
