AB350 Gaming-iTX/ac - freezing (oh no...)

First of all- Good info here.

Let me share my experiences so far. I have played around with my new computer for a week now and I must say That it has been a bit challenging but also a time for learning since I must say it is not exactly plug and play at the moment :-)

For the new ones reading I wanna confirm that the windows version on install is very important! I wasted a lot of time there :-)

 

First of all- I can confirm the cold boot bug, where it loose all the settings.

I can also confirm the bug mentioned that sometimes the CPU is not able to downclock but keep pushing on at a constantly high level after being challenged (Have especially seen that in relation to 3D-Mark.

 

I have been messing around quite abit and I am not done yet :-) but let me share a few of my experiences so far.

 

I dont OC the CPU at all anymore (above the 3600 Mhz) because this breaks the whole boost funktionality- So unless you OC to 4000 Mhz you will only get higher base power consumption and less peak Mhz! That basically sucks.

An interesting thing however that I have noted is that the standard voltage that the BIOS set for the CPU voltage seams to be quite high. many people have been scared about that and have clocked it down. I have noticed however, that Ryzen master also give it a high default value (3,5 V. if I remeber correctly). In the example with screenshot on AMD's homepage with the 2400g on ryzen master the CPU Voltage is put to 1,4 V for an 4000Mhz overclock. I suspect that this chip with the boost funktionality need a somewhat higher CPU Voltage to accomodate for the boosts than what many expect.

 

I have played alot with the ram settings and the APU because I really wanted my ram to run with the 3466 Mhz that is the maximum for my board. I have managed to make it post and I can also finish some tests, but it is not stable in games. I really want to try and OC the ram as much as possible because the performance from this is much better than increasing the clock on the APU-GFX relatively. Besides you dont create the same temperature issues with high ram speeds compared to OC the APU-GFX. I tried to increase the timings without much succes- Just some trial and error. If anyone have some experience to share please do. My ram are G. SKill Ripjaws V. 2X8 3600Mhz. 16-16-16-36 (F4-3600C16D-16GVK).

 

As a note I measure my temperature with CPUID Hardware monitor and I have 1 crazy temperature 115 C on one of the measurements (cannot remember the exact naming bu T??something) but I guess it is some bug in the software - Can anyone confirm this? The other ones are around 40 +/-.

 

I had my ram clocked to 1,4v. (Back to 1.35V. again). but more interesting I have had the VDDCR SOC clocked to 1,28.. V - I know that many will consider this crazy high- which is probably true, but since that SOC feeds both the RAM and the APU I wanted to try and see if I could get it more stable by raising it a bit. The reason for this was, that I found it very difficult to OC the APU higher than 1350 Mhz. So I wanted to see if the issue was that the RAM took all the juice. I could get some quite good numbers in benchmark, but it was not stable so now I have clocked the SOC and RAM down a bit again.

Now I am back to 1,3V. for the CPU (Not OC because I want the boost funktionality and keep the power saving when idle) I have the ram running at 3333 Mhz with 1,35V. The VDDCR SOC is 1,2 and the APU GFX is 1300 Mhz. After reading Cristys last comment I will also try and see what happens if I lower the voltage a bit for the ram- Maybe to 1.25V or 1.30V.

It is however not very stable. I can play Crysis 2007 good on medium settings 1920X1200 for about 5-10 minutes and then I get a windows popup with the program has to close down??

If I try to raise the APU GFX to 1400Mhz it will crash by some grafic mess screen or freeze- So I am thinking that I need to lover the RAM more, increase the VDDCR SOC or maybe I am getting to hot. Any ideas?

 

Can anyone recommend some software to measure temps within games and tests? When I rush out of a game or test to see the temperature measurements it has already cooled down a lot, so not easy to really see. I have tried the MSI afterburner  but I cannot make it show the right sensor- Just shows 0 degree.  

 

Sorry for the long post but I am not native english speaking so I am excused for not being able to keep it short and exact :-)

Hi,

there's some serious bs going on with this whole plattform right now ...

My "cold boot issues" are definetely caused by my RAM settings, I get it every time. However my RAM runs just fine as far as I have testet it. I played AC Origins for hours with medium and low timings (low CL 14/14/14/14). I'm actually using G.Skill 4000 C19 with Samsung B-Dies which are confirmed to run 3200 mhz / cl14 with 1.4 V.

Now there could be 2 reasons for the issue.
1. There's a bug in the timing or voltage settings that causes the failure at boot
2. There's a bug in the AM4 RAM Training fuction.

I turned this off now just to see what happes because my RAM runs absolutely stable with these settings. It also boots and reboots with this settings everytime until I unplug my PSU and reboot the next day. Weird...

EDIT:
OK, to make sure my RAM is stable I just ran a full pass MemTest86 > no errors with 3200 / CL14 @1.4 V. It's definetely NOT my RAM.

Enter UEFI, and change overclock settings from ASRock Settings to AMD CBS then go to /AMD CBS/Zen Common Options/ and switch Core Performance Boost to Disabled, this should fix 90% of stuttering and frame drops, you will still have Adaptive Frequency and Voltage but you will loose Turbo and XFR so CPU part will be limited to 3.6GHz on all cores, the GPU part remains at the same frequency as before. I dont know if it will help with the cold boots but worth checking EDIT: you will need to switch to AMD CBS Settings from ASRock for this setting to stick

OK, going to check this tomorrow, have to get some sleep now!

I'll be back with an update.

Only a short update ...

Today again cold boot issue, again the RAM settings where reset as well as GFX settings.

I went through the process of calculating the HEX/DEZ numbers for my RAM timings and enterd them in AMD CBS settings. Also turned off Core Performance Boost.

Now the stuttering is gone as you described it but turbo also is off now but ok that's at least something.

Again, my RAM was absolutely stbale with my settings, I'll try lowering the voltage next time too because I think it would run those timings on 1,35 V as well.

I hope ASRock will patch these problems soon, it seems to be a specific problem here, isn't it?
AMD is working closely with MSI, that's garbage...

Indeed you are right, I mentioned this before, on the AB350/X370 Fatality ITX there is no SOC/GFX voltage monitoring entry in the UEFI, you should not exceed 1.25V SOC/GFX, a voltage monitoring entry should be added for SOC/GFX because the CPU has sensors for this and has outputs for displaying these voltages but ASRock decided its easier not to add these entries in the UEFI....
