I'm disappointed with the Asus service regarding support for 4 way crossfire using 4 separate cards, and have been waiting for months for an updated bios, after I informed tech support of the issue back in march, so without further ado, meet the supermicro X9DRG-qf:
This is the motherboard may be changing towards, as the current Asus board also has some limits relative to memory capacity ( 8 slots, 256 GB memory capacity maximum), since I plan on adding at least another 128 GB of ram, but don't want to scrap the existing memory, which with it being registered and ECC is not exactly cheap, and it needs to be a board that can support 4 GPU's at full PCI-e 3.0 X16 speeds, so without further ado:
16 memory slots with a 1 TB ( yes, 1024 GB) memory capacity, and I plan on plugging in my current cards and either a pair Intel E5 2690's (10 core / 20 thread , 3 Ghz base, 3.8 Ghz turbo mode, 25 MB L2 cache), or a pair of E5 2697's (12 core / 24 thread, 2.7 Ghz base, 3.5 Ghz turbo mode, 30 MB of L2).
Even with 4 cards plugged in ( 4 R290x 8GB cards which I already own, water cooled), still has enough lanes open for an additional LSI SAS card for storage ( I already have it ), and a Creative THX sound card ( already own that too)....
It's a much larger board than the usual ATX standard, but I have a case that can handle the beast just fine (XSPC cube case, with the motherboard laid out horizontally...)....Clocks in at 15.2" x 13.2" (38.6cm x 33.5cm) size wise. so it really is proprietary.
Main thing is the memory, with the ability to pack up to 1 TB, and handling up to 24 cores / 48 threads well it's safe to say that an upgrade after this isn't coming any time soon....LOL
Checking all the information available before pulling the trigger, but it seems like the best option out there....
