Stay away XI Hero 1704 bios

[Adrian1983]

Hey guys,

There seems to be new Memory settings added to the menu in the picture. Have I missed something here? Has these settings always been there?

Attachment 86880

Hmm I don't remember these either from memory so I'm not too sure to be honest.

new settings
"Lpddr Dram Odt"
"DDR4 Skip Refresh Enable"
"Late Command Training Relaxed Reset"

BIOS 1704 for MAXIMUS XI CODE faulty, bcs. same settings with BIOS 1704, XMP 1 for DRAM 3200MHz (1.350V) doesn't work, need 1-2 minutes to reboot with unstable post message (DRAM set to 2133MHz with 1.200V), 1.350V is not accepted
I test all new function with Auto, Enabled and Disabled
"Lpddr Dram Odt"
"DDR4 Skip Refresh Enable"
"Late Command Training Relaxed Reset"
and --> MEMORY TIMINGS and PRESET = MODE 2
XMP like manual settings and other settings --> nothing works
I go back to BIOS 1602 and the sytem boot/restart in 3-5 sec. and works perfect with XMP1 with 1.350V / DRAM 3200MHz --> perfect.
BIOS 1602, Improve system stability --> perfect
BIOS 1704, Improve system performance --> negative ;(

Yep I was getting instant lockups with prime95 blend with my 3000mhz ram @ 3600mhz with 1704, I've now flashed back and happy days, Thanks Asus! In future add a full description to your bios updates, You must be the worst i've seen for changelog and messing around with RAM settings making systems unstable!

funny with this bios I can boot my RAM 4100mhz with my 3200mhz kit. Before it didnt boot and everything else is also stable. Running 3900mhc CL16 OC

I have a somewhat similar experience with a Gskill 3200 C14 kit:

1602 bios: 3900 C16 stable @1.3V; 4000 C16 stable @1.5V; 4100 C17 often fails to post
1704 bios: 3900 C16 now requires 1.4V; 4000 C16 not stable anymore; BUT 4100 C17 stable @ 1.45V; I even managed to post @4200 C18 for the first time

The new bios also requires slightly higher (+0.05v) vccio/vccsa for me for similar frequencies; it's still safe though at 1.15-1.20v@4100-4200 Mhz.

I will stay at 4100 C17 with the new bios v.1704 and try to get 4200 C17 or C18 stable.

now got to work semi easy 4000MHz 16-17-35-1N with tight secondary/tertiary timings with 1.45v and SA/IO 1.13v/1.18v. My kit is TridentZ 3200CL14 2x8Gb. Best BIOS so far for me. I used BIOS Flashback feature to update my bios (cos modded bios with newest RAID OPROM). Dont know if there is any difference with issues seen here compared to EZ-Flash.
