For Ambient behavior there is again another guide from Falkentyne in the OCN.NET forum -> LINK

---
 

-- BIOS FLASHBACK PORT

Red marked is the BIOS FLASHBACK PORT, Rename your File to MZ790A.CAP before flashing.

-- Mainboard Buttons / Measurement

-- Microcode Switch
There is a new feature for switching the Microcode on the current BIOS, current is default (no need to switch for now)image.png.70afbdc75e32c6ce0ca9d80bfe9f25fc.png

 -- Safe Boot Mode
If you change the BIOS slot and then restart the motherboard, the first boot will automatically start with the safe boot mode.
So if you forget to reset ln2 settings nothing can happen on ambient 🙂

-- MC SP Check

Tests the MC solely, without touching the DRAM (you can even remove the dram while its testing) , same mc on different boards/dimms should give similar score
Tests the FMax of an MC at a fixed low SA voltage. In the same way you test a core's fmax at a low voltage idling.
Since there is an element of luck when testing FMax like you would when running for a cpuz record, the outcome will not be 100% the same everytime and score will shift a little.
Temperature affects FMax but the effect is weighted and the maximum package temperature during the training is taken into account to generate an unbiased score.


 

-- LN2 behavior

With the new crazy clocks unfortunately comes a problem that about 2/3 of the CPUS have a hard CB. No RSVD switch or another voltage seams to help here.

Currently there are some chips that are close to -185C -> Fullpot, there may be something you can try here. Try tightening the socket screws more and before remounting the POT. Put the graphics card into the very last slot. Use the original IHS instead of the custom bracket, we have had better results with high wattage loads. For legacy stuff the bracket is still a choice, maybe the better one for single core loads. Peak load with all Ecores ~ 950W+, so you have to watch out if the paste cracks.

Memory IMC uplift is also huge, the same MDIE memory now runs between 7400-7600 memstable under air and up to 8500+ for various benchmarks. For those who have an ADIE kit there is a 7600 profile in the bios that you can use as a starter profile.


As starting point set the LN2 Jumper on Mainboard, go into BIOS, load the LN2 Profile and Cool down to -120C

Basic LN2 Settings are:

Ratio 55
Cache 40
Vcore: 1.60 - 1.70+
SA: 1.35+
CPU Input Voltage: 2.0

Core PLL Voltage 0.915 - 1.00500
Ring PLL Voltage: 1.00500
PLL Termination Voltage: 1.300
CPU Standby Voltage: 1.300
CPU Input Voltage Reset Voltage: 1.8

-- BIOS naming rules

here are some naming rule that you can identify bios in which status

Official bios, it will be 0x0x or xxxx, e.g. 0806, 2204 and can download from official website, but there will have a time delay between it build and release, sometimes you can download it from ASUS RD, but can’t find it from official website becasue bios is on internal testing and need time for approval

Test bios, it will be only 00xx, e.g. 0040, 0051, modify for improve compatibility or system stablity

Special or meida reivew bios, it will be 9xxx, only offer for specific using to solve issue or for media review before it official release

all bioses will based on official bios and modify for improvement

Test:
0075 - 0088 - 0095 - 0099 - 0031 (MC SP Visible) - 0040 - 0005 - 0078 - 0088

 I just tried the 0801 bios for the Z790 Hero seems it is messed up seriously for my memory so have to go back to the 0703 from the Asus site.

On the 0703 I can easily run the basic XMP I and II at 6400 Mhz. Even go up to 6800 with the same profile not even adding voltages. I have run a tighter profile with a bit higher voltages fully stabile at 7200 Mhz and can boot up at 7400 Mhz.

 

On the 0801 Bios i can not even boot a simple XMP profile XMP II nor the XMP asus tweaks even at 6400 with the same ram sticks.

I am using the Kingston Fury Renegades 6400 Mhz 2x 16GB.

I am playing around with some GTX580 cards on the Z790 Hero. They cards are PCIE gen2. Even if I use the switch on the Hero to ensure it goes back to Gen3 the Bus interface in both Win8.1 and Win 10 shows up as PCIE x16 1.1 @ x16 1.1  now it should be reporting PCIE X16 2.0 @ X16 2.0 as per all instances i see back in time (other platforms)

Is there a way to fix this?  It is as if the MB is holding back the scores in Heaven, 3d Mark Vantage to mention a few. This even if I run 6Ghz CPU and 7GHz on the ram with tight timings

Did you update Intel ME software and firmware to the latest?

My 790 APEX can do A-DIE 8800 boot on air by gear2 mode, but failed to same 8800 by gear4 mode. Have tried different CPUs and BIOS but nothing better, any idea? :(

Which bios? I think it only works on certain bioses from what I have seen people say and also needs lower voltages from what I remember.

 

I think one of these newer ones that it worked on 0078 or 0088. Not sure.

After playing around with G4 on the apex and hitting 9600 on ambient, (only tried bios 0806 and 0810)

You need much lower SA, around 1.25ish for it to start working and you need to play around with the strap + BCLK, too high and it wont boot, and sometimes too low and it won't boot. (I was doing 10000 strap and 89 BCLK, and then adjusting BCLK inside of the OS)

Mess around with your IVR and MC Voltages too, those might need to be a bit lower than what G2 needs for 8800. Have fun.

THX. I booted G2 8800 with normal timing, must I use raw timing for G4 at the same mem Freq?
