I've been playing with the guest specs as well.
Please let me know if I can be of any assistance in your server memory upgrade. I hope this information was helpful to you. Here are some links to the Kingston Configurator if you need some guidance. Depending on the Xeon E5 model installed, this server supports up to DDR3-1600 (12.8GB/s per DIMM) at 1.5V (E5 v1) or 1.35V (E5 v2). The ProLiant D元60e G8 also features a triple channel memory architecture, with six sockets arranged in two banks per processor. Not everyone needs that boost, however, which is why the third bank is there to give you capacity. So it's best to avoid using the third bank if you need that extra boost of performance from the memory.
#What is the differance between pc3 12800r and pc3 12800e install#
Once you install memory into the third bank, the memory will automatically toggle down to 1066MHz (8.5GB/s per DIMM) at 1.5V. It's also not a good idea to mix different types of chips across the channels, as this can cause unforeseen stability and performance issues.ĭepending on the model Xeon you have installed, the G7 servers support up to DDR3-1333 (10.6GB/s per DIMM) in 1.5V or 1.35V in two DIMMs per memory channel (six DIMMs per processor). This can be a significant difference in available memory bandwidth for your application. When DIMMs are not matched across channels, Rod-IT is correct that they will operate in single channel operation. DIMMs should be installed in identical groups of three to optimize for the best performance. The D元80 and D元60 G7 servers feature a triple channel memory architecture, with nine sockets arranged in three banks of three per processor. When upgrading your 1P ProLiants, here are some factors to keep in mind. Am I correct? Is downsampling a bad thing? If it isn't a bad thing is it better to go that route and save the cash or should I go the Edge route and stick with all 10600 memory? I assume that if I stick PC3-12800 RDIMMs in with my 10600 they will be downsampled to 1333Mhz. If I go with something like Edge, I can get 10600 16Gb at CDW for $192 (though these are marked as "call" whereas the ones that are available in 1-3 days are $280 which is inching closer to HP branded memory) and 8Gb for $105.
Crucial doesn't appear to have PC3-10600 RDIMMs in 8 or 16. Just want all the info out there.)Ĭrucial has 8Gb PC3-12800 RDIMMs for $100 and 16Gb PC3-12800 RDIMMs for $173. (Incidentally, the systems all are using ECC at 1.35V. I believe the plan is workable so far, but if I'm incorrect, please let me know. Finally I would use the two RDIMMs I removed from the D元80 G7 and use those along with the additional memory in the D元60e G8 for a total of 42Gb.
I would take two of the RDIMMs out of the D元80 G7 to make room for the new RDIMMs. I was thinking about adding 24Gb (an 8 and a 16) to each. I've been asked to increase the memory on the servers. I've got the following three servers (all HP Proliant with single processors):ĭ元80 G7 with nine 2048mb x 1333Mhz RDIMMs (PC3-10600) for a total of 18Gbĭ元60 G7 with six 2048mb x 1333Mhz RDIMMs (PC3-10600) for a total of 12Gbĭ元60e G8 with two 8192mb x 1333Mhz RDIMMs (PC3-10600) for a total of 16Gb
