I tested the unlocked 1.2.0.7, every benchmark was slower, R23 by almost 600 points. I went back to the unlocked modded 1.2.0.3c .I have that one unlocked if you want and can post my BIOS settings for the unlocked stuff.

Actually, I don't have the unlocked Tomahawk 183. You can ask @Eder on this Discord if you want.

Hey, can you link me the unlocked one, and your bios settings ? Ty

1, you would get more memory, you might not get quite as high clocks, post on the 24/7 memory forum about that as I can't give an authoritative answer as I'm on 4 x 8 bdie, 5800x is more or less resolved with the latest bios, it might even pay to run the 1.2.0.3 bios as that's the fastest non 5800x3D bios, if you get the 5800x3D instead of the 5800x then run the latest AGESA

I'm not seeing the 1.2.0.3 bios on MSI support bios page :/ only 1.2.0.3b

I did a google search for best bios for 5800x and this is what I found in a redit thread. One guy at the end of the quotes below is saying he is on 1.2.0.3b because all the new bios's make his CPU run hotter.

x570 Meg Unify - CPU hotter with any newer bios

Hello, using a 5800x cpu here. Stock, no OC, all default bios settings, only XMP enabled.

Every bios for my motherboard since version 7C35vA8 released on January, makes my CPU run hotter about 10º. Idk what msi has been doing with the latest bios, but I find myself forced to use this bios because otherwise, during a intensive workload my cpu temp shoots up to 90-91º.

Just to make sure it wasn't something else cause the high temperatures , I tested this again. And yes with the January bios, my temperature is around 83 during intensive stuff like cinebench. With any newer bios it instantly shoots up to 91 and stays there. All with default settings.

I don't know if MSI hasn't been caring enough about the 5800x to test their settings, but I'm pretty sure they are feeding the CPU way too much voltage by default.



I found this via Google. Exact same issue, thought I had something bad, bought a new fan.. turns out rolling back to the bios to a previous version fixed this, apparently AGESA has issues with EDC or something? I'm on 7C35vAA, down from 7C35vAE.

Is their a 1.2.0.3 bios that I would want to run the 5800x on?

Or is the 1.2.0.3b I have installed the best bios for the 5800x?

The reason why 1.2.0.7 bios is slower is because MSI again broke the power telemetry reporting. With 7C35vAA I had "power reporting deviation" as reported by hwinfo64 at 102-103% but with 7C35vAE it is again at 110-111%, like some older BIOS were. The fix is easy if you want to restore performance, you should configure CPU VDD_Soc Current Optimization in advanced settings. I put "CPU VDD Full scale current" to 234A for my 5900X and it performs now the same as before.

Any one tried or is using the Fan Control software to control fans?

I have it working but one of my system fan headers on the mobo are not detecting correctly as well as two sensors on the 1080 Ti GPU sensors. Wondering if it's from the Bios I am using or software related issues etc.

Here is Jay's .02¢ talking about and showing how to use the Fan Control software I am asking about. Where I downloaded it.

 

[DarknightOCR]

I don't know if this has already been mentioned in a previous post.
but bios 1.2.0.7 still have the EDC bug?
I wanted to switch from 1.2.0.3c to 1.2.0.7 to see if a 5950x can boot to 1900mhz IF.

the 5900x did without any problem in 1.2.0.3c

 

[dk_mic]

yes, all AGESA after 1.2.0.3c have this behaviour of reduced vcore when EDC > 140

 

[Spilly44]

Thrown a wobbly here.Bios reporting temps and voltage wrong.eg cpu temp 0deg c Core voltage 2.048v,DDR voltage 0.2v but further down says 4.066v.All fans in bios stuck at 65536rpm.
Cannot alter the speeds of any fans.But once in windows Ryzen master reports correct temps and voltages.Also the debug leds have stopped working.Tried a different bios but still the same and emergency usb bios flash is not working.Bios button flashes 3 times and thats all.Will try further bioses later but not looking good.Any help Appreciated.Smiffy.

 

[Spilly44]

Well spent 2 hrs sorting it and no joy.Left it for 3 hrs while I watched a film.Cam back and its all ok now.Bloody gremlins.

 

[Spilly44]

Am on latest bios after troubles.On a 3950X.Seems the LLC setting may not be working.Tried Mode 1,2,and 3 but vcore reads 0.900v with all 16 cores at 2.5Ghz but when running occt it drops to 0.88.Have tried latest bioses AE,AC and AA and its the same.Any help ta in advance.Am going back through bioses.Always found A42 best for memory but A7 was as good but needed slightly less voltage for 15,14,14,14.

Anyone download the newest MSI Unify Bios, anything change as far as outperforming 1203c yet, or is 1203c still the KING for 3800/1900 Cl14 overclocking. Wanting hit that 4000/2000 Cl16 without any 18/19 whea errors....just doesn't seem possible for me.

 

[Spilly44]

This thing is giving me crap this week
Adata X70 blade shows up in windows 10 but not in the bios
Going through bioses to see if that helps but any inf appreciated

 

[Spilly44]

Fixed.Buggered MBR

This thread does not seem to be as active as it once was.

I was never able to find the 1203c bios just the 1203b so that’s what I’m running atm with the 5800x.

For those using the 5800x3d, is there a best bios version for using the x3d and PBO/ with XMP enabled? Any specific undervoltage offsets to use?

 

[sendap]

I am running the latest 1.2.0.7. I have not tested 1.2.0.6
Currently there is no PBO or CO option available on BIOS level (for X3D). For that use PBO2 tuner or wait for 1.2.0.8
I would not recommend undervolting due to the risk of clock stretching. There is really not much to tune on the X3D. Use PBO2 Tuner or Kombostrike 1/2/3 to reduce temps.

 

[dk_mic]

So here are BIOS versions and AGESA verions:

AB1 / AB3 are 1.2.0.3c with SMU 56.52
AB2 is 1.2.0.4
AA0 is 1.2.0.3b with SMU 56.53

I think you want 1.2.0.3c if you are running 5800X on win 10. Newer AGESA have 1.425 VCore limitation if EDC > 140.
AB1 and AB3 might be identical.. AGESA Version and SMU are, AB2 was a buggy 1.2.0.4 BIOS

For windows 11 you might want to use the latest BIOS (it runs on 1.2.0.3c, but there were some fTPM stutter issues that were fixed with BIOS updates iirc)
I am pretty sure for a 5800X3D you need 1.2.0.6c or newer and my guess is the best BIOS is the latest one.

here you can download unmodded BIOS, MSI forum mod site (?)

I recently picked up a 5800X3D and an MSI MEG Ace Max X570S and saw this thread, though not the exact model it must be similar enough

waiting for alphacool eisbaer 280 to come in then going to build it up, put som PBO2 on it and let it rip

 

[N2Gaming]

I have the x3d just sitting here unopened and waiting to be installed. Ran some benchmarks with the 5800x and saved the screen shots to compare to the x3d.

Is there a way to save the bios settings and print them out so that I can use them again later after a bios flash. My system is running pretty solid atm and don’t want to loose the settings if I don’t like the x3d.

Take a screenshot of RYZENMASTER settings -that should show you what you need, or do what I do, take a phone pic of the bios screens

 

[N2Gaming]

That is the obvious way to do it if there is no way to save every setting to a text file but the text file shows every single setting in one list.
