I recently built system with Ryzen 3950x and MSI MEG x570 Ace. The issue I am having is the stability. If I increase the limits with only 10% - I cannot pass full cycle of prime95 blend test. It freezes or reboots somewhere between 2nd - 8th hour.
Here are the system specs:
MSI x570 Ace, bios v17 (latest)
EK performance 360 water cool kit
2x16GB gskill F4-3200C14D-32GVK (and also tested with other 2x8GB kit)
PSU be quiet dark pro 11 1000w
pbo - advanced, limits - manual - PPT 156W, TDC 105A, EDC 154A.
Other bios settings are on their default/auto values.
This is not supposed to happen I believe or it would make pbo completely useless.. damn only 10% makes it unstable. It does not overheats, I have hwinfo logs during the prime tests and can share the data.
Could I have bad cpu or motherboard? (I exclude the memory because I confirmed the same behaviour with another memory)
Could I do something in order to get stability with at least 10%-20% increased limits?
P.S attached is some hwinfo data from first 2 hours of prime95 with no increase of limits (green) vs 10% increased limits (red).
