Thoughts on Maximus z390 1401 Bios

[LordSabathan]

Since i cant find the thread for bios update on z390(where ppl sharing thoughts on the bioses) and i see there is a new bios for Code ... i appriciate if someone share thoughts on this bios , since the last 2 or 3 versions where not very good.

to the CPU PLL OC Voltage:

i looked in a oc thread of 9900KS cpu's and the voltage was only 1,216v with the old bios... there was screens from 5,1-5,2Ghz cpu's.

Whats the name for VCCST in HWiNFO? Thx!

I just got my board second hand with an old bios and updated to 1401. Last few days was feeling a bit upset trying to get my Gskill Trident Z Royal F4-4266C19D-16GTRG to run at xmp.......best I could get it to was 4000mhz so pretty unhappy. Even then pc took a bit long to boot and couldn't get into bios without going into windows then doing a reset first....

After finding this thread I went back to 1302 and instantly xmp is fine and stable. I even tightened up the timings a bit an no issues.

Currently @4.266mhz 18-18-18-38 stable 🙂

THANK YOU SO MUCH EVERYONE!

Thank you Jekel for sharing your TridentZ 32gb settings,
I too have had much m u c h trouble with these,
so bad I reverted back through the old bios releases and for my set the 1005 bios works the best by a wide margin. (Much better than 1302)
I would like to update to a newer bios and hoped that they had fixed this issue with the new 1401, and you clarified that for me my friend, so thank you!

Asus, please make a bios that works with Trident Z 32gb kit (My plan was to double the kit with another 2x16gb but when I cannot get the first to work properly...)
Long time ASUS supporter here, altough a bit dissapointed with you now ASUS... 😕

Anyways, to all you mates, may the force be with you!

The best Bios for 4x8gb B-DIE for P0 Stepping i think is 0602.
A other good for R0 Stepping is 1302.
Bios 0602 is the most stable by GSAT, best Training was 1302.
Max. GSAT stable by my System is 4x8GB @4400CL17-17



1401 is Crap for B-DIE.


Best reached Frequency was 0602 with 4x8GB@4600 CL17-19

G.Skill Trident Z RGB DIMM Kit 32GB, DDR4-4133, CL17-17-17-37 (F4-4133C17Q-32GTZR) / Asus Maximus xI Extreme / 9900KS

1401 make problems to get the ram HCI MemTest stable..

[Laelys]

same problems like Mappi75 My ram don't work with bios 1401 and work fine with 1302 ... So returning to 1302.

@Laelys

I got two kits which wont "work" with bios 1401:
G.Skill Trident Z RGB DIMM Kit 32GB, DDR4-4133, CL17-17-17-37 (F4-4133C17Q-32GTZR)
G.Skill Trident Z RGB DIMM Kit 32GB, DDR4-4266, CL17-18-18-38 (F4-4266C17Q-32GTZR)

Which kit did you own?

With Bios 1302 both kits work out of the box via loading xmp I profile and set VCSSA & VCCIO voltages manually.

This is my 3rd 9900KS which has a good memory controller - which did not need very high voltages:

4.133
DRAM: 1,40v
VCCIO & VCSSA: 1,14375v

4.266
DRAM: 1,45v
VCCIO & VCSSA: 1,2250v (which i have to test a litte more if its 1000% stable with hci & karhu memtest).

i install the bios 2 days ago. I do not see any difference on my 9900k at 5.0 at 1.35 I drop to 1.30 with. and bot scenarios are ok. no issues. BUT! i do detect a 2C to 4C increase of VRM temps. Since windows is using axv the numbers of the LLC are correct with what i put on the bios. and maintain that value. I have to check on the memory side. I do not use OC aside of the XMP 1/2 and I do manual VCCIO/VCCIA adjustment. 1.15 on both using my 3600mhz (32ram quad configuration since i purchase as a quad kit.) I will check later pm games how it does. aside that is the same as the 1302!

G.Skill Trident Z RGB DIMM Kit 32GB, DDR4-4266, CL17-18-18-38 (F4-4266C17Q-32GTZR) don't work with bios 1401
But my Corsair 4000Mhz works fine with 1401

DRAM 1.45 VCCIO 1.424 VCCSA 1.408 With Gskill and Bios 1302 (XMP II)
