I have a server mothebord S3420GP with 6 memory slots.
Now, I have 2 slots filled with these: 2x KINGSTON 4GB 1333MHz DDR3 ECC CL9 DIMM with Thermal Sensor.
Is possible to use another 4 these RAMs? So I would have 24 GB RAM with 6 x 4 GB. Is this combination possible?
Or is possible to use 4 x KINGSTON 8GB DDR3 1333MHz CL9 ECC Dual Rank BOX.
So total memory size will be 32 GB RAM.
Thanks for any answers.
Memory population rules on S3420GP is kind of complicated.
If you're using a Xeon 3400 series processor, you can use either RDIMM (registered) or UDIMM (unbuffered), but you can't mix RDIMM and UDIMM. If you're using Core i3-500 series or Pentium G6950 processor, only UDIMM is supported. ECC is required for both RDIMM and UDIMM.
Now for RDIMM you can populate all six slots. For UDIMM you can use only four DIMMs, two each channel. # of DIMMs per channel will also affect the DIMM speed. Maximum memory capacity is 32GB RDIMM or 16GB UDIMM. For more details, see the S3420GP Technical product specification, section 3.2.
You can also try the Memory Configuration Tool. It will tell you what memory combination you can use.
Last but not least, always select memory from the Tested memory list.
Strange as it may sound, but memory listed as supported on Tested memory list, does not really work. I had bought 32GB (8GB x 4) of make: Hynix, Model: HMT31GR7AFR4C-H9. And it just failed to be detected by the motherboard.
I was trying to use it with 2 Intel motherboards (S3420GPLC & S3420GPLX) along with Intel Xeon 3430. I tried with both motherboards but it just wouldn't work.
I have tried this with 2 different DRAM vendors with same result and ended up doing an RMA :-(
Is there something special that you need to do when using Registered DRAM?

Hi Forum , Hello Intel !
Whats going on here with this thread?
I Own a S3420GPV Board with 16 GB and Xeon 3470. Now I would like to upgrade to 32 GB.
As I read here in this thread the ram from the testet ram list is not working. Are there any news?
I dont want to order Kingston, Samsung or Hynix modules if they are not working as described above ...
Any solutions Intel ?
Thanks a lot,
I think this question might get better addressed in the Server Tech Support Forum. For future reference the thread can be found at: http://communities.intel.com/message/124240#124240
OK I fixed this problem !
I tried modules 3 times , and now I ordered 4 8 MB modules of Kingston PC3-8500 1066 MHZ and they work like a charme ....
