Re: [casper] DDR Memory Modules for Roach2

[Ryan Monroe]

So I have an application where I'd really love to use a 16 GB dimm.  
What do you think are the chances we can get one of those approved?  (I 
might be able to do some of the legwork myself / hack up the gateware 
controller as needed)

Are there any special addressing considerations for ROACH2?  I remember 
we had an address pin unconnected on ROACH1

Thanks

Hi Jason,

I think Mo had different Kingston DIMMs which are not 1gig, but the 
supplier claims that they are compatible. We have to be very careful 
when choosing the DIMM as we can only support a few different modules 
as the gateware controller has the SPD information hard coded.

I am unsure of the status, but Alec will be able to help out, when he 
gets into the office tomorrow morning (South African Time).

I noticed the wiki page heading read ROACH DDR3 Memory. I have changed 
it to ROACH2 DDR3 Memory. So the link is now at 
https://casper.berkeley.edu/wiki/ROACH2_DDR3_Memory_Modules

    The following web page lists two memory modules for use in the ROACH2:

    Kingston     KVR1333D3S8R9S/1G
    Samsung     M393B5773CH0-CH9

    Mo at Digicom was only aware of the Kingston Module as being
    approved for use in the ROACH2.  He also reported that the
    Kingston Module may have some problems as well.  Can anyone give
    me updated information on this topic?
