I’m sure many of you have dealt with trying to figure out how much RAM you can shove in a box, say an R720, and still keep RAM speeds up. I actually had some docs from Dell, figures, diagrams, graphs, and a few charts. Even then, it was difficult.
Enter the “Dell 12G Memory Solution Tool”. It is a website that allows you to test RAM & CPU configurations to get optimal speeds. For instance, you can select the R720, 2 CPUs, and that you want 256GB of RAM. That’s a nicely sized box for virtualization. The tool tells me I can get 16x 16GB of 2R4 DIMMS at 1333MHz or 1600MHz. Of course, I’m going to go with the 1600MHz! What if I want to bump the RAM? I checked out 384GB & 512GB to see how they stack up; 384GB gives me the option for 24 16GB DIMMS, but drops my speed to 1066; and 512GB has two options, either 800MHz, or 1333MHz (yes please!).
It also shows you some quick price & power consumption rankings on a 1-5 scale.
Pretty awesome, imo! Here’s the link: http://poweredgecpumemory.com/
Hi,
I am planning to go with PE 720, 64GB or 128GB option and RDIMMS. Two CPUs in this PE720 (E5-2690)
What will be best performance for 64GB? Using 8x8GB or 4x16GB?
What will be best performance for 128GB? Using 8x16GB or 16x8GB?
Assume all are Dual rank dimms.
Thanks!
For absolute best performance with no regards to power in the configs you have indicated you should go with:
For 64GB: 8x8GB 1600MHz
For 128GB: 8x16GB 1600MHz
Cool, thanks.. Going with 8x16GB 1600MHz
