P620 max memory limit

2020-12-06, 19:41 PM

Hello,

 

The P620's Specs  suggest that max memory limit is 512 GB. Is this a hard limit (say, imposed by the motherboard) or does it only represent what has been certified/validated ?

The Threadripper PRO supports 2 TB and Lenovo's P620 launch PRs advertised 1 TB support.

The P620 thinkstation-specs page show was we fully support on the platform.  When we originally put together these public specs data, the highest capacity memory DIMM that we fully supported on this P620 platform were the 64GB DIMMs.  Putting 8x 64GB RDIMMs in a P620 would give you a total of 512GB of RAM.  

Just recently, we just qualified 128GB DDR4 3DS RDIMMs on the P620.  Installing 8x 128GB RDIMMs would give you a total of 1TB of RAM.  We need to get this information updated/corrected on the thinkstation-specs site.

In order to get to 1TB of memory, you'll need to install 8x 128GB RDIMMs in the system.  Unfortunately, this is being blocked due to a defect found in development.

Thanks for the info.  I'd like ask you two further questions:

 

1. Would it be possible to install 4 of 256GB first while this issue is being resolved?  If yes, when would 256GB be available for purchase?  

 

2. If I install a 3rd party RAM, GPU or PSU, would it void warranty?

 

Thanks!

On #1, sorry I meant 4 of 128GM RDIMM. So, if possible, I'd like to start playing with 4 x 128GB

I think we are able to support 4x 128GB RDIMMs at this time.

Great! Could you let me know when 128GB RDIMM would be available for purchase? And could you also clarify on the second question (copied below)? If I install a 3rd party RAM, GPU or PSU, would it void warranty?

I'll find out what the status is of ordering 128GB RDIMMs for the P620.  

 

Normally, installing 3rd party RAM, GPU, PSU, etc will void the warranty.
