Hey guys,
your Youtube video brought me here. I recently purchased the MSI B350 Tomahawk along with a Ryzen 1700 and 4x8GB Corsair LPX rated "3200Mhz 16-18-18-36" (<- what's on the box). PSU is a Corsair AX760 Platinum, GPU is a Zotac 1080 AMP! BIOS is up-to-date.
I really got some trouble and stability issues with that combo, hope this is the right place to ask. Neither Reddit nor the official MSI support was able to help me.
I overclocked the Ryzen to 3.8Ghz at 1.275V and the memory to 2667Mhz at 1.340V, 14-16-16-34, CPU NB Voltage 1.085V.
The machine runs totally awesome, it's been prime-stable for 8h, Blender CPU rendering stable for 6h, rest of the time 4k gaming, zero issues.
Here's the problem:
On each reboot the machine turns off, then on for 0.5s, then off again, on again -> then boots without issues*.
Sometimes, pretty randomly, it's worse: Turn on -> off -> on -> off -> on and BIOS shows auto-reset message, I need to enter the BIOS again and load my OC settings. After that on-off thingy the machine runs fine as described before.
*(To clarify, it doesn't reset any of my OC settings after that on-off procedure, like it would if you entered arbitrary values that just don't work.)
After a few days of trial & error I kinda "solved" the issue by relaxing the timing to 22-22-22-38 and increasing all voltages. This is kinda sad cause all components run at much better values except for the on-off issue.
Second problem:
Sometimes I boot into Windows 10 and HWMonitor shows only 2-4 (it's pretty random) cores overclocked to 3.8Ghz while the rest of the cores is at 3.2Ghz. (?)
I already re-seated all components, unplugged external hardware, changed the BIOS battery, tried running with only 2 of my 4 memory sticks etc.
Anybody has a clue what's going on?
Thanks,
Manuel.
EDIT: MSI's answer to all these problems was basically "Erm yeah... we're still working on it.."
