Thnx for the replies.
It would seem that for the ram to work it must be
512mb x 64 x 8 is the max module size of 8 gig.
ECC must be Unbuffered Not registered
I found a guy here who installed one of the original 48 gigs on a pt6 board
the reading I did there last nite is where I came up with the above,many have come & asked direct questions regarding
Memory as well as other questions on the X58 platform.
I did locate a local source for 4 gig sticks however 2-4 weeks delivery $ up frt.
these are Gskill low density looking over the reviews F3-1600C11S-4GNT
seems the quality was in question back in 2013-15 however recent reviews appear everybody happy.
As for the server I listed I wont be buying it on a chance it has what I need it likely has ddr3 8500 in it @ best pc3 1333,it was just proof they are still out there for cheap.
I'm looking for some pc3 1600 to get me past my 165 BLK, my kingston 1333 value ram may if I loosened the timings & raised the Vdimm but unlikely to be stable.
Valid available part numbers as of today
there is also a place called data micro systems which have a huge selection of all types of modules
mostly server but some non ecc I forgot to ask if the enquiry I made if the ECC was unbufferd
"We do not differentiate between 1Rx8 or 2Rx8 on our DM50 668. It can be either but my current stock is all 2Rx8"
$19.95 per 4gig stick DM50 668
$24 per 1866 ECC unregistered DM61 788-1 he's checking on if it is 1r or 2R
located in New Hampshire
10600 & 12800 non ecc only 1,2,4,8, gig models very cheap
seems the 8 gig are 1024 x 64 so NOGO there but ok up to 4g.
which suits for me.
