Fatal1ty x399 won't post with 128GB RAM

from a quick read around on a google search

it would seem at present its not going to be cured by even using another brand of board

both gigabyte and asus seem to be having the same problem with x399
its just not liking 128gb/8 sticks

most users posts/feedback is cant get a boot with the 8 sticks, one or two guys have managed after many many hours of manual tweaking, to then be presented with windows not seeing all of the 128gb
phrases like '96gb system reserved'

i have literally found just one person stating they have had success
that was a gigabyte board and corsiar dominator platinum ram at 2400mhz

iif it was me guys

i would use the stable 4 sticks in quad (64gb) and stay with what you have for the later bios updates

(of course support tickets sent in with EXACT details of the ram kits and your board will help the bios/tech team to get the kits working)

Sorry but i don't want a workaround to have a stable configuration, i need a fix. I build my workstation/configuration for a virtualization lab and not for gaming pourpose, 128Gb is a must for my pourpose...i don't expect an enterprise support from Asrock...but if I haven't a resonable respone from the support whithin tuesday, I'll change the motherboard for another brand. @128noGB and @MisterJ if you consider to change MB pay attention to Gigabyte X399 Gaming 7, it have the same issue  http://forum.gigabyte.us/thread/1854/x399-gaming-128gb-ram-issue Waiting an ASrock response! PS. Yestrday i'm able to install VMware ESXi 6.5U1 on our buggy MB, OS see only 16Gb ( with 7 sticks installed, BIOS see correctly 7*16Gb)..10Gbit nic are not discovered (but 2 nic are enough to my lab)

Ahh, I must keep SVM enabled then as it is required for what I'm using this for as it is virtualization as well.

4x RAM sticks work just fine also.  No hardware reserved.  This only occurs with 7x RAM sticks.

I'm doing 4 sticks stable (no hardware reserved in windows).

Does it change if you do a BIOS upgrade with 4 stable sticks VS 7 sticks plugged in)?   Note:  You can't do a BIOS upgrade with 8 sticks since the system won't POST.

Also, the error code is always:  C0      with 8 sticks. 

This may not be your issue but where I have seen this behavior it was the command rate. Where 1 T works fine with the 4 sticks and even the 7 before attempting 2 quad channels. When 2 quad channels are used it probably needs the 2T timings.

They pulled 1.60 due to a couple of repeatable issues.

It was explained to me that 1.50 is stable.

My recent posts are directed at 128noGB as we are also conversing via PM and I do not want him getting out in front of me in my diagnosing HIS 128GB(16GGx8) Kit issue.

Note: I am not a fan of upflashing a BIOS on a perfectly working system in the hopes of only flashing in the hopes a User will gain 100fps. If it's working, IMO, leave it alone.

If that 128GB Kit only works with 7 sticks installed and a recent BIOS addresses their/this 128GB issue, then by all means use Instant Flash to upflash.

MisterJ, clearer now how my recent posts relate?

Sorry for the confusion everyone.
