Hi:
 
Before posting this, I have checked most 96GB posts on this forum. I have not seen anything that could help me, if not to get rid of all this memory and get some new one from Kingston or Crucial. I just cannot afford this right now, after spending $350.00  on this kit I am talking about here:
 
I have just purchased a 48GB kit (6 x 8GB sticks) used. It is Hynix HMT31GR7BFR4C-H9 memory ECC.
 
I already had 48GB (6 x 8GB sticks) of Samsung M393B1K70BH1-CH9 ECC which work fine and are recognized at full value (48GB).
 
The Hynix kit I just bought, on its own, is also recognized at full value (48GB), meaning if I only use the Hynix kit.
 
If I mix 3 x 8GB on each CPU of the two brands, I still get 48GB recognized at full value.
 
The minute I add 1, 2 or 3 sticks more per cpu (in the order suggested in the manual), either the same brand per cpu or mixed,  the machine no longer posts at all. It goes into a booting loop, never posts, but you can see the codes changing on the Post LED display in the same order over and over again. They stop at b9 or b8 which codes by the way are not listed.
 
I probably cannot return my purchase, so this is a big let down.
 
Any suggestions. I know absolutely nothing about overclocking or changing timings, etc. But if I have to go this route, how do I change the BIOS values when the machine does not post at all.
 
I run a pair of E5606 cpus.
 
Thanks in advance for any response.

Mixing different brand memory modules is a bad idea, try to set manually the memory timings to the slowest brand.

Hi
I too, have two sets of 48GB, they are suppose to be all Kingston, same model number on the package, but the original kit was Kingston and the later was Kingston/Hynix.
So I guess you can say they are all Kingstons, but they are somehow different... or they just don't have the same tolerance when you use 12 sticks vs 6x I am not sure.
I do know that I am not able to do the overclocks I used to do when I only had the first 48GB.
So for me its, probably to sell them and get 96GB of Crucials 1600 ECC
All the best and sorry for your trouble...
