So what you are saying is:
You would like to see a simpler, more intuitive BIOS interface.

While I agree, there is a broad spectrum of users from completely ignorant all the
way to extreme enthusiasts that actually want more options opened up, you need
to bare in mind that the vast majority of the confusing elements are RAM related.
In many cases users simply can't get their rated performance out of the system
without these advanced options. The KISS solution would be to enable XMP and go.
If it doesn't work, return the RAM and buy a different kit/model. Repeat till it
works. The simple truth is that the system is only required to operate at the
frequency supported by the CPU's IMC. Anything beyond that is technically an
overclock.

RAM manufacturers have confused the issue with XMP. Most people today assume that
XMP = default speed for that RAM. It does not, it is an extreme profile the RAM
manufacturer expects will work on most systems but they do not
guarantee it.

All that said, I fully agree that the BIOS can be a daunting thing to work with,
particularly when settings are poorly explained and duplicated all over the place.
ASRock used to have a simple UEFI screen that you would see by default
but many users hated it and it got scrapped. Personally, I like ASRock's BIOS
implementation, I appreciate how much they leave exposed for the curious and
the experienced to play with. If it wasn't for RAM issues on AMD, I doubt many
people would complain. Being forced to search for a dozen or more settings just
to get your RAM to work at or near it's XMP rating is a pain, no one will deny
this.

I can understand that. Nevertheless:
It must be clearly stated that a manufacturer who creates complex high-tech products for the consumer can not assume that one is an offspring of Einstein and can answer questions about the product himself. If the producer or support takes the liberty or is ordered not to answer specific questions normal mortals, then I don't need the product. Then they can keep the high-tech product among themselves.
What I'm saying is: as long as not dealing with quantum physics, I have to assume that the producer should then be smart and capable enough to strictly follow the principle of Keep it Simple, so as not to have to evade unpleasant questions from the consumer about compatibility when the product is released.
To keep a long story short: The design of the X570Aqua is simply awesome. So far so good. The BIOS is IMHO a disaster. And since I don't stare at the mobo all the time and struggle more with the BIOS, the overall concept is inadequate.
What I want to say: In my opinion, a producer of a 1000$ high-tech product should be able to create a BIOS interface that can satisfy the 1mV enthusiast up to 7000 Mhz on the one hand and also the butcher with 4 clicks up to the operating limits. Everything else simply has no future.


Please, correct me if I am wrong.

That's pretty much the whole problem, AMD needs to be more transparent with all
this. Board partners have to skate a fine line between upsetting their vendors (AMD/intel)
and upsetting their consumers. There is no perfect balance, someone will always
be angry. Many times when an obvious solution is not mentioned or explained by
a manufacturer's support staff it is simply because they are not allowed to.
AMD and Intel have stipulations and conditions for licensing their products.
If a piece of advice or explanation is in violation of those conditions, the
poor tech support person is not allowed to say it. This applies to all board partners.


To be fair to ASRock, they often get in trouble for putting their consumers first.

The memory controller is on/in your 3950x .. Ryzen 3000 series generally don't go to far beyond 3600.. 3733 is what AMD considers optimal .. but, baby steps .. does your memory run at 3200 with fclk @ 1600£ ..if yeah .. try faster until you max out what the memory controller on your chip can do .. ideally you'd want to run your fclk (infinity fabric) at a 1:1 ratio .. with the RAM you are running, you can go for real tight timings at slower than XMP rated speeds for about the same performance.

Hello all. Hope you are all weel

For almost a year now the hardware combination of
Asrock X570 Aqua,
Ryzen 3950x (BIOS 3.40) and
Corsair Vengeance 32GB (4 x 8GB), DDR4-4600 Samsung (CL19-26-26-46)
(Powercolor 6900 xt liquid devil)
gives me severe headaches and i am having a really hard time to figure out whats the problem is.

Whatever BIOS settings i use i neither get the CPU clock beyond 4700Mhz nor the 32 GB memory anywhere near to 4600Mhz.
And certainly not both at the same time. And what is really annoying is that once the XMP2 Profile (1) selected leads to permanent reboots. For any reason the memory is locked at 2133Mhz.

Memory QVL (Vermeer) Compatibility list from Asrock.
DDR4 Corsair 5000 5000 8GB CMK16GX4M2Z5000C18 Ver:3.31 SPECTEK     
DDR4 Corsair 4866 8GB CMK16GX4M2Z4866C18 Ver:3.31 SPECTEK      
DDR4 Corsair 4400 4400 8GB CMK16GX4M2F4400C19 SS 2
DDR4 Corsair 4200 4000 8GB CMK64GX4M8X4200C19 ver4.31     
DDR4 Corsair 4133 4000 8GB CMK32GX4M4E4133C19R     
DDR4 Corsair 4133 8GB CMK64GX4M8X4133C19
DDR4 Corsair 4000 4000 8GB CMK16GX4M2Z4000C18 ver 3.31 Micron     
DDR4 Corsair 4000 8GB CMR16GX4M2F4000C19 ver4.31     
DDR4 Corsair 4000 3866 8GB CMK64GX4M8X4000C19
DDR4 Corsair 4000 4000 8GB CMK16GX4M2K4000C19 Samsung B-die      
DDR4 Corsair 4000 4000 8GB CMK32GX4M4K4000C19 SPETEC      
DDR4 Corsair 3800 3800 8GB CMK64GX4M8X3800C19 ver4.31      

The Corsair Support tested the functionality with only two bars and a very early BIOS version. The request to test again with 4 bars and a current BIOS version could not be granted because 2 more bars were not available. By the way: The 4 memory bars of 8GB (32GB) cost me 1000$.

Can someone here please thankfully tell me what the hell I am doing wrong. I have a wickedly expensive system here and I'm driving with the handbrake on.

And before I forget: Dear Asrock Team, I've been gaming for 40 years, and have built 20 rigs myself so far, and the Dsign of the Asrock X570 Aqua is absolutely fantastic. No question about it. But please don't ask me what I think of your BIOS. I can't remember ever seeing anything worse for $1000. And to use Doubler Chip to gernerate 14 power phases out of 7 is.......

Please don't ask me, because I could answer pretty badly for $1000.

Board model: X570M Pro4
BIOS version: 3.40
CPU: 3900X
RAM: HyperX Fury 2x16GB DDR4 PC4-25600 HX432C16FB3K2/32

Notes: XMP profiles (3200/3000) doesn't work properly. Spontaneous restarts. Overclock it manually so hard and I can't get a stable system (Spontaneous reboots).
But it works on default frequency (2400).
And it worked correctly at a frequency of 3200 on old firmwares (2.x series).

Have the same problems with the same motherboard (X570 Steel Legend), also with BIOS version 3.60.

The most irritating is the freeze when entering the Super IO settings in BIOS. Have to reboot after that.

Also, the XMP setting at 1.4V and 4000 MHz does not work.

Board model: B550 Phantom Gaming 4
BIOS version: 1.8
CPU: Ryzen 5 3600
RAM: Crucial Ballistix Gaming 16GB (2 x 8GB) DDR4-3200 PC4-25600 CL16 BL2K8G32C16U4B

Notes: Board delivered w/ 1.4 BIOS, stable w/ Ryzen 5 3600 at default BIOS settings. Updated to 1.7, enabled XMP, system was flaky (flickering screen, black screen). Disabled XMP and manually set memory speed to 3200. Updated BIOS to 1.8, at the recommendation of Crucial tech support. Enabled XMP and system is stable, with voltage set by XMP to 1.35. I don't know if XMP under 1.7 BIOS set memory voltage up from default 1.2v (still feeling my way around UEFI and Ryzen/RAM specifics).

Conclusion: for this Crucial Ballistix RAM, BIOS version 1.8 and XMP appears stable.

Board: B550 Steel Legend
BIOS version: 1.90
CPU: 5900x
RAM: 2x16GB G.Skill B-Die@3733

All benchmarks dropped and no way i can get any core to boost above 4975MHz while 5025-5050 was easy on several cores with UEFI 1.80.
Using the same PBO settings and Curve that just run as expected in 1.80 but not 1.90.
It behaves as if the Curve Optimizer using negative values does nothing for the maximum boost clocks while it obviously does with 1.80.
Ryzen Master still shows the wrong value for VDDCR if set in UEFI -> OC Tweaker\External Voltage Settings
