I've been looking to build a server and I have an S3420GPV which I want to use, however the RAM requirements are extremely confusing for me. On the technical document, it says no support for x4 or x16 RDIMMS, and no support for Low Voltage DIMMS. It also says that for 16GB RAM you want quad rank 4GB DIMMS but it gives support for 6x4GB Dual Rank DIMMS if you want 24GB RAM (Obviously not possible in the V as it has 2 slots per channel) however that leads me to believe that it should work with 4x 4GB dual rank DIMMS.
This is conflicted when I go to the supported hardware though. Most of the 4GB DIMMS listed there are 2Rx4 DIMMS, and some are even 1.35V (low voltage). So now I have absolutely no idea what to believe.
For example - KVR1333D3D4R9S/4GI
It's in the supported hardware list for my motherboard, however kingston say it uses 512MB blocks. The TPS for the motherboard says it does not support 256/512MB technology.
I know this product's support ended years ago but I'd have thought is someone might be able to explain things, I might find them here. I've even found documentation that states registered memory isn't supported in the V variant but I do not believe this is true.
