This motherboard has 8 DIMM slots.: A1 A2 B1 B2 C1 C2 D1 D2
The problem is that the board doesnt seem to post when i use D1. it will hang with a screen supermicro screen that has B7 in lower right corner.
The Manual says to first populate (x)1 slots first which are blue. If i have 1-3 sticks going from A1 to C1 they all work fine. I have verified that all 4 modules post individually if in slot A1. it all seems to work well accept when i try to use D1, then the board fails to post. Originally I bought 4 16GB sticks, and seemed to isolate 1 that was not working. I did memtest on the other 3 individually and they all seemed fine, so I just assumed i had one bad stick.
Today I just received a new 16GB stick. doing tests with the config today it seems that the board will post when i use A1, A2, B1, C1 (using A2 instead of D1) The bios shows 64GB at 1600 MHZ.
manual says :
When installing memory modules, the DIMM slots should be populated in the following order: DIMMA1, DIMMB1, DIMMC1, DIMMD1 then DIMMA2, DIMMB2, DIMMC2, DIMMD2.
The motherboard will support odd-numbered modules installed (1 ,3 ,5 ,or 7 modules). However, for best memory performance, install DIMM modules in pairs.
and :
Populating these DIMM modules with a pair of memory modules of the same type and same size will result in interleaved memory, which will improve memory performance. Please refer to the table below:
So..... should i do some more tests with the current config that posts (A1, A2, B1, C1 ) or get in contact with the seller and try and get a exchange/return/repalcment Board ?
The BIOS defualt setting for Channel inetleaving and Rank Interleaving is Auto, in the bios It does allow me to change settings:
DDR Speed
Use this option to force the system memory to run at a different frequency than the default frequency. The available options are Auto, Force DDR-800, Force DDR-1066, Force DDR-1333, Force DDR3-1600 and Force SPD.
Channel Interleaving
This feature selects from the different channel memory interleaving methods. The options are Auto, 1 Way, 2 Way, 3 Way and 4 Way.
Rank Interleaving
This feature selects from the different rank memory interleaving methods. The options are Auto, 1 Way, 2 Way, 3 Way, 4 Way and 8 Way.
Should i set CI to 4 way and RI to 8 way , and run some tests ? leave it in Auto and run some tests ? just go for a motherboard return ?
Thoughts ?
