Has anyone successfully used an 8gb or higher stick with the Classified SR-2?
 
I was looking back at the original manual for this board, and if I understand correctly the maximum memory per stick mentioned is 4gb.  I am not sure if that is because 4gb is the maximum supported per stick or because the manual was published back in 2010.  Maybe that was the maximum any manufacturers made back then but the board can support higher?

They did not have 8gb sticks back then. I used 8gb sticks on my EVGA x58 Classified3 and my FTW3 boards.
Gskill Sniper DDR3 1866 no issues at all. I ran 2 on them for total 16gb

It seems 4GB/slot and 48GB Max.
I have a English sr-2 mannual in my conputer but now I am not at home.

Is It usual? my supermicro X58 (x8dtl-6 nearly the cheapest level) can use 16gb/slot.

Yes that is definitely what my SR-2 manual says too. 
 
However I am wondering if maybe that is just because 8gb sticks were not invented when that manual was published. 
 
I would love to know if anyone has successfully used a stick larger than 4gb in the classified SR-2.

Upon further investigation, it seems like the answer is that yes, some 8gb ECC memory works with this board to bring the max capacity up to 96gb.  More details here: https://forums.evga.com/8...s-on-SR2-m1538509.aspx

I have samsung 96GB ecc ddr3 working perfect on sr-2.
So 96 GB is working.
Most 8gb modules not working on sr-2.

I currently have an 8gb stick plugged into memory slots A1 B1 and I have slots A2 and B2 empty, and the computer is working, the manufacturer says my board can handle 16gb, but it never  specifies 4gb per slot. Is this an ok config or am I going to burn up my mobo? I have 2 more sticks of 8gb ram, all 4 sticks are identical, I figured before I plug it in and see if my computer turns on, I would ask advice here. I'd rather not permanently damage anything.

Hello, I can confirm that 96gb of Samsung ecc 8gb M393B1K70DH0-CH9Q9 M work on this board.
 
I will comment my case, I purchased the SR2 in 2011, and it was working flawlessly with 48gb of 1600MHz GSkill 4x12 modules, suddenly in 2017 the board stopped from recognizing all the memory, sometimes 40gb, others 44gb. And I was not able to overclock it anymore, even 1Mhz, it was running at 200MHz FSB all the time, with no overvoltage in any component.
 
I swapped the E5645 xeons with no luck, same result, I tried all memory combinations, swapping all modules in all possible combinations, same result. All memory modules were fine, It seemed that two black memory slots of CPU0 were broken.
 
I was forced to leave only 3 memory sticks on the CPU0 socket in the red slots, and I left the black slots empty, and the CPU1 with all the 6 memory sticks running, total 36 gb, the reason for this was the triple channel, if I left the memory in an asymmetric configuration (40gb most of the time,44gb sometimes), the performance was ridiculous, at the point that winrar benchmark fell from 18.800kb/seg to 2.800kb/seg.
 
So I decided to purchase 2 xeons x5690, the top for this board, the memory issue was not resolved, the problem persisted.
 
Later I decided to purchase 96gb of this Samsung memory (thank you Robbanswe for your post), to see if I have more luck, and yes, the 96gb are working fine, so no damaged memory slots, no xeons damaged, no memory sticks damaged, so.... A COMPLETE MYSTERY.
 
I will not overclock anymore this board, now I have a decent cpu clock speed with the x5690s and 96gb of ram, 1600 Cienbench R15 points, and it seems that the passage of time has done its job doing the motherboard more sensitive.
 
I decided to share my experience in case it is useful to someone else and to thank Robbanswe for his message putting the memories that work.
