MSI Tomahawk B350 RAM cold boot issue
« on: 16-July-17, 02:45:53 »

Hello together.

I have a issue with my msi tomahawk b350.

I use 2x G.Skill F4-3200OC16-8GVKB in my pc and a ryzen 1700x + msi gtx 980 ti. Iam on the newst bios (1.60).

I want to let the ram run with 3200 or at least 3000 mhz. In the bios i easly can switch to 3200 or 3000. By using the profiles or manuel setting the frequenz to it.

I can reboot my pc, no problems. I have no crashes, i can shut down and start my pc without any problems.

BUT

As soon as i remove the power from my pc for around 10 mins or my pc is off with power pluggin in for a much longer time and then try to start my pc i get this strange issue.

My pc tries to start for 3~5 seconds (fans and light on), but goes off asap and tries to come up again and again for around 3~5 rounds. Then he starts but reset my ram to 2100mhz.

Is there anythink i can do to fix that? I want to remove the power over night to save energy.

Thanks for your help guys!

Hi

It sounds like RAM OC is simply unstable. Set your RAM to 3000MHz and run Memtest, see if it finds any errors with this OC.

Hey
I have this issue too
My config: 1) B350 Tomahawk 2) Ryzen R5 1600 3) HX426C15FB x 2
On cold start sometimes the MB resets my ram to 2666 and processor to 3.2 GHz (but in bios shows 3825 MHz, in windows 3,2 GHz)
But in OC they both work fine with 3066 MHz and 3825 MHz fully stable (2 hours memtest and 1 hour linpack AVX). 
On the bios 1.71 this happens less often than on 1.6x, but it happens

The double cold boot is an old issue and has been seen on all platforms. Usually it is caused by ram oc or a certain combination of ram, cpu, bios version and mainboard.

It is no real problem but just annoying. Always check for the latest bios version. You can also try removing the ram oc.

Totally agree, it's just annoying, but it would be very cool if this bug was fixed in the future

It might be not as it is very hard to be duplicated for the reasons already listed.

MemTest done, no errors found. Iam already on 1.6 (which is the newest bios for this mainboard). With 1.4 at least 3000 mhz worked, but it seems i have to go down to 2667mhz :-(

Seems like iam not the only one with this issue :-(

Sorry I see a very similar error. I cant get 3200 like the other user but the computer reaction is the same.

I learned that i will never buy AMD.... They always have problem. The temps on A10. Here Ram. Next time better buy intel.

Trust me my friend, intel has problems currently too. Skylake x lineup is a fiasko. Currently ryzen is on the better side.

But still, i really hope msi start to address this issue. I never had such a buggy mainboard from you guys, you can do it better, i still have faith in you.

There's one, little problem: it is AMD that dictates the rules. Some RAM works fine, others doesn't.
Nonetheless, I'd suggest you ask MSI directly: >>How to contact MSI.<<

Hi, and greetings from Germany and, sorry for my bad english.

I can actually tell you what exactly is the problem.
To resolve the problem you need the feature for pre boot voltage Regulation at your MSI Mainboard, and of course right now they dont have it.
The feature is called VDDR_Boot and you neeed if for OC Memory.
Why ? Well, the Memory needs at the cold start of the machine an extra kick of Voltage (1,45V) to work,
after the voltage kick, its getting back to your normal reference point.
How do you can test it by yourself ?
Easy.
1. Get first to the point where you get the cold boot bug.
2. Your System will shutdown and start again, after the restart immediately push the restart buttoon 1 or 2 times.
3. If the shutdown happens again, try it again, but on normal Conditions it should boot to Windows and runf with your +3000Mhz Ram Range.

You have to do this all the time, the only real solution is through a BIOS Update with the Feature VDDR_Boot, if ist even possible.

Ok strange things happening now...

Support suggested me to try memtryit and set up all the settings for the ram manual. Memtryit did not worked. But setting the ram on manuel helped at least for 2 days...

Now i have these stranges reboots again, after this the bios is telling me that iam on 2133mhz. But in Windows (CPU-Z and the AMD Master Tool) he is saying that iam still on 3200mhz!? So who is now lying to me? Am i on 2133 or 3200? And what strange issue is that?

I think this is incorrect voltage/ProcODT settings
I had similar problems, but after adjusting these settings (for me ProcODT = 68.6 Ohm, CLDO_VDDP = 0.965 V, DRAM and SoC voltages should be tuned too) cold boot and reboot work fine (bios 1.60)

WOW! Now i am at 2933mhz!! i cant get 3066 or 3200mhz. But now i am happy with 2933

Are you on 3200mhz or 2999mhz?

2999mhz worked fine with ProcODT = 68.6 Ohm, CLDO_VDDP = 0.965 V and DRAM/SOC Voltage on Auto. But as soon as i try to enable 3200 i get reboots.
If you are on 3200, what is your current
DRAM/SOC Voltage?

If you are on 3200, what is your current
DRAM/SOC Voltage?
I'm on 3066 MHz, SoC Voltage = 1.15 V, DRAM Voltage = 1.38 V
I think that my ram will not work on 3200 MHz, because the memory chips are produced by micron. But I try it with every new version of bios =)
I'm happy with 3066 CL 14-16-15-33 1T (HX426C15FB/8 x 2), even if sometimes my PC has issue with cold boot...

All other MB manufacturers have the cold boot issue too (including X370), may be new AGESA microcode will solve this issue in future... At the moment, you can only reduce the frequency of the problem

So:

SoC Voltage = 1.15 V
DRAM Voltage = 1.38 V
CLDO_VDDP = 0.965 V

for 2999mhz or 3066mhz

If i would like to go 3200mhz in the future with fixed AGESA microcode, can i use the same settings or would you suggest to i increase or decrese some of these values?

With future updates you probably will need to adjust and find the working spot once again.

Even with 7A34v18 (AGESA Code 1.0.0.6b) i still dont get my F4-3200C16D-16GVKB to work with 3200. Iam still between stable 2800mhz and 70% (70% means sometimes he need 2 boots to come up, but after that the system runs) stable 2999mhz~3066mhz.

So two new Bios updates in the past:
7A34v19 and 7A34v1C both with: " Improved memory compatibility." and new AGESA Code but still no luck getting my rams faster then 2933mhz :-/
