Ram for crossfire hero viii and ryzen 3950x

[Zach_01]

SoC Voltage or VSOC is the entire I/O die voltage.
cLDO VDDP is the (UMC) memory controller or UCLK.
cLDO VDDG is the InfinityFabric or the FCLK.

Infinity Fabric connects the I/O die with the Core die. Also connects the 2 CCXs inside the Core die (CCD).
UMC and IF is essential to CPU/Ram connection. So those voltages could stable or unstable the system.

Some boards have distinct voltage control for the 2 ends of IF (cLDO VDDG). The I/O-Core connection (VDDG IOD) and inside Core die (VDDG CCD) between CCXs.

To determine the actual voltages of these parts you should have the ZenTimings (v1.1.0 or v1.2.1) software.

cLDO VDDP/VDDG voltage can’t be equal or above VSOC, as those voltages are being derived from VSOC.

this is my situation what do you think ?

 

[Zach_01]

Like most boards, you may have at BIOS VSOC at 1.1V but the actual is less. Usually boards set it around 1.05~1.08V. You can increase it a couple of steps at a time to reach actual 1.1V (1100mV) and also increase cLDO VDDP around 1.0V (1000mV). And see if stability improves.
IMO past 1.15V for VSOC won’t benefit anything really.

yes by default in docp without touching anything it automatically sets to 1.1 but I had reboots with this voltage the screen you see and because I changed it to 1.09v so I guess I will have to go up above 1.1v and not go down

 

[Zach_01]

Yes, you need to set it above 1.1 to have it really at 1.1V. Maybe 1.11~1.12 or even more. You will see ZenTimings...

Sì, è necessario impostarlo sopra 1.1 per averlo davvero a 1.1V. Forse 1,11 ~ 1,12 o anche di più. Vedrai ZenTimings ...
[/CITAZIONE]
Right now as I was writing it restarted twice by itself and this did it even with voltage at 1.1v in idle without stressing anything my current bios situation is this in the picture

 

[Zach_01]

Did you increase it at 1.12V? I still see it at 1.09V...

 

[Karmal]

Did you increase it at 1.12V? I still see it at 1.09V...

no now I try...here is my current situation .. let's see if it goes out
update went off after 3 minutes two reboots in a row with these settings
I exaggerated .. I exaggerated .. automatically gives me 1.081
now i'm trying to 1.095

 

[Zach_01]

Along with VSOC increase, try also to increase CLDO VDDP to 1.0V or 1.05V

for now I have only brought to 1.11 the vsocc from bios that in zen timings gives me this this .. see if it turns off in the next few hours

 

[Karmal]

i used the pc normally for about 10 hours and it didn't shut down but it's too early to say victory what test could i use to see if everything is actually stable? even though most of the time it went out I wasn't doing anything stressful

I will do more tests but I think it is difficult to maintain 128 GB at 3600 .. at this point I would have decided to take less gigabytes of ram and faster and more stable without acting on the voltages. I don't understand why asus certifies memory at 3600 and even at 4600 mhz when it doesn't work

 

[Karmal]

nothing to do yet reboots changed soc to 1.1 and dram to 1.36

 

[Karmal]

Here's what Asus said about my sudden reboots. Thank you for contacting Asus support. The reported problem, since the memories are included in the QVL list, is caused by an error in the installed Bios version. Does the problem occur only when 4 memory modules are installed? If the problem does not arise without the activation of the DOCP profile, please try to configure the memories manually by selecting a lower frequency and check if the system is stable.

Try rollback to BIOS version 2103, last BIOS only for Zen2 with AGESA 1.0.0.2. It was rock solid BIOS almost with any Zen 2 CPU, QVL memory kits and DOCP. If you want newer BIOS, try version 2311.

This (2103) worked for me thanks.
The newer BIOS (3003) I couldn't even set DOCP. Had lots of crashes with R9 3900x on Hero VIII - Happy Holidays

I rewrote to asus about abrupt reboot issues with 128gb 3600mhz ram (4 32gb banks) which i am continuing to try at 3600mhz here is the answer:
Regarding the problem encountered with 32 GB memories, if possible, we invite you to install the bios 2702 version that you can download from the following link and inform us if the problem persists.

We take the opportunity to give you cordial greetings.

I did try this BIOS and to no avail - would still have sporadic crashes. Tried them all frankly until I read your post and went back to 2103. The only one that sort of worked was 2502. My memory is the G.SKILL Trident Z Neo 3600 MHz F4-3600C16Q-32GTZNC, which supposedly is designed for this system. I have to say that lately I have grown more disappointed with ASUS - I guess since they introduced their armoury crate approach.

yes but I have a 128 gb ram very different from your 32 gb and everything is much more difficult to make stable I will try all the bios after which I will put back my previous ran from 64 gb to 3000 mhz which was perfectly working in docp

then I can no longer return to the previous bios who helps me?

A beta version 3101 is released for asus crossfire hero viii wifi in the meantime I went back to the 2502 let's see if it works for me too


nothing the 2502 doesn't work for me i had a reboot in docp with 128 gb of ram now i upgraded to 3101

As far as I know you can return. You can try from within the BIOS and if that does not work use the BIOS renamer for the BIOS you want to go back to, and rename it to CH8.CAP on a USB drive and use the BIOS flashback function. As far as I know you can flash back to any BIOS using this method. 2-14 in the manual has more.
