" rel="nofollow - Hi, Is anyone here who is using a X399 board with 128 GB of ECC RAM memory? I'm intending to get such a system soon, but I'm afraid to sink $5k into a build that may have issues or not work at all. Cheers Trax |

" rel="nofollow - TraxXavier, I think ECC is not a problem. We have seen other X399 user with ECC and doing fine. We have just started to see users with successful 128 GB with the latest BIOS. We do know that there are AGESA/BIOS updates needed. Please see my post here: http://forum.asrock.com/forum_posts.asp?TID=6534&KW=vendor&PID=39062&title=memory-vendor-comment-on-x399-agesa#39062 I have done very little ECC research but I seen to remember that it tends to be less fast, so you will probably be OK. Be sure you select a vendor (like G.Skill which I think may not sell ECC memory), that is good with RMAs.

I wonder why ASRock does not test some extreme setups that would be good publicity. |
