Ket, you can tell if your modded f9d or f22b is Windows 7 compatible?
Since i’m using B350 Gaming 3, the official sh*t UEFIs is not compatible since F5~F6. They updated and removed the Windows 10 Features options, making impossible to change for “Other OS” wich i think is the option to make Windows 7 run without pci.sys d1 error BSOD.
there’s a little problem with your F23 bios.
i can’t boot from cd if i want.
- if i’ve got a cd in my driver, and if i push F12 when i must, i’ve got three bip from my rig.
- if i let a cd in my driver without pushing F12, same…3 bips.
to boot from a cd, i must not put the cd in the driver, enter in the bios, put the cd in the driver, close it, then go to choose to boot from the cd in the bios…
very strange
Probably related to boot devices. Under Fast Boot > SATA Devices, change the option to "all sata devices".
I always expose the Win 10 Features options in the modded firmwares so F23 should work fine once the setting is changed to "Other OS".
You will do a modded F23 for B350 Gaming 3? If so, i’ll love you forever. xD
will test this.
thanks 
Hi, Is it possible to change how the SOC Voltage automatically changes itself when using a higher specified memory frequency as supported.
Ex, If I run my RAM at 3000MHz, the SOC Voltage is at 1.1V – If I change my RAM speed back to 2400MHz, the SOC Voltage will run at 0.9V – There’s no option for me to manually decrease the SOC Voltage, but only to increase it, set it to Auto or leave it as (Normal)
I’ve seen other boards run higher frequency RAM’s at 0.9V SOC Voltage just fine.

@atomfix41 :
You should be able to manually change SoC voltage, keep cycling through the options with the “+” and “-” keys on the keypad. As for can I change how the algorithm works that would be a negatory that algorithm is deeply buried and I have no idea where.
EDIT by Fernando: Fully quoted post replaced by directly addressing (to save space and for a better readability)
I tried. It will only give me the Auto, Normal and + it never goes into the -
The higher i increase the memory frequency above 2400MHZ it automatically applies a higher SOC voltage with no option to decrease it, only to increase it 
Hey @atomfix41
Could you please provide a screenshot of the Voltages screen from your UEFI Interface… Thanks in advance!!!
P.S. What helped me out was seeing it to "NORMAL" after & if I enable XMP Profile… SoC Voltage sticks ~1.114V 
Hi. Can’t really tell you if something missing since I’m not using any fastboot settings since first zen + compatible bios because it won’t allow me to get into bios if I use fast or ultra fast boot. I can test it later and let you know. Once again thank you for the spent work on this
Here’s a pic with Auto. If I leave it on auto, it will give my SOC some bizarre voltage of 1.35V when im running the RAM at 3000MHz
Here’s a picture with “Normal” this will leave my SOC Voltage at 0.9V if I’m running my RAM at 2400MHz. Now if I start to increase my RAM speed in increments ex, 2566, 2600 etc etc, it will bump the voltage up automatically in Normal mode to 0.95V - 1.0 - 1.1V etc
Here is the next option after Normal, We’ve now in the + range. If I leave it on +0.00 it’s basically the same as leaving it in Normal mode, only increasing in increments after it’s automatically pre-determined voltage that it gives you, with no way of returning to 0.9V at 3000MHz
Getting the SOC to undervolt would be great. My CPU idle temperature is now 27C instead of 34C <that’s with SOC at 1.1V If I can get it to 0.9V with the RAM at 3000MHz, I can hopefully have more overclocking headroom on the stock cooler, as it’s topping out at 80-85C at 3.6GHz @ 1.18V
Gaming k5 fast and utra fast boot working. First time Im able to use this since getting this board. Either u are a miracle worker or gigashit fixed the bios. thank you anyway
@atomfix41 That looks like GB have completely pulled out the ability to manually enter a SoC and CPU voltage, very, very strange decision from GB.
From what I’ve heard on the GB forums, on the K5 there never was a way to manually enter SoC and CPU voltage. GB say it’s a hardware limitation of the K5.
P.S.: Has anyone here experienced the sleep bug? The one where on waking form sleep on F23 the memory voltage drops from 1.35v to 1.2v if it was set to Auto…
@orondf343 I’ve not seen that bug before but I always set voltages manually anyway particularly with GB boards can’t trust them as far as you can throw them. I’d also be very surprised if GBs excuse of “hardware limitation” is true. The K5, K7 and plain 5 as far as I recall are all built on the same PCB just with a couple bits missing / added depending on model. Not being able to manually adjust voltages would also just be a very bizarre move so… I’m just not buying it. Not saying 100% GB haven’t done that, it would just be one of the most backward decisions I’ve ever seen.
Force those settings to User w/ AMIBCP doesn’t help you set negative value or manually go to 0.9v?
Now, as for your SoC Voltage… AMD RYZEN MASTER DOES Allow you to undervolt SoC Voltage between 0.9V-1.4V… As well as VCORE & DRAM Voltage… The downside beIN they don’t stick after rebooting… Try this combination… Enable your RAM XMP Profile AND SET SOC VOLTAGE TO NORMAL when you boot into Windows verify your Voltages with AIDA64 and/or HWinfo…
I’ll esit this post once I get home in a few hours with some of my screenshots ok…
@Lost_N_BIOS I’ve looked at the K5 firmware for those options just now GB have outright pulled them out of the firmware… might be able to reverse engineer something thought, not sure.
That’s crap! Sorry for opening my big… I didn’t look, just assumed they were there but hidden from other similar BIOS I’ve enabled them in before.
Reverse engineer… Maybe pull modules from previous, was it there previously? I’m sure your already considering that, thinking out loud to help
The chip on the K5 board that controls the voltages and clocks has LLC capability too. GB Has also removed that option.
Is it possible to edit the voltage table so that when the memory is running at 3000MHz that the SOC is automatically stuck to 0.9V? I can confrim that using Ryzen Master to set the SOC Votlage to 0.9V with the memory at 3000MHz works, but resets back to it’s original 1.1V at every reboot. I can also confirm that the SOC at 0.9V is also bench stable with the RAM at 3000MHz, CPU is running a lot cooler too which enables me to run a higher CPU clock with the stock cooler.
