First time posting here, so let me share my recent experience with the MSI 390.
I have an i7 2600K with 8 GB DDR3 Ram, an Asus P8Z68-V Pro/Gen 3, an Evo 850 SSD and 4 HDDs, and my previous card was a faulty Asus GTX 970.
Upon receiving the MSI 390, I installed it on this pc running Windows 7 64 bit after running DDU and CCleaner to get rid of previous drivers.
My problems started shortly after, with random crashes on nearly every game and performance hiccups due to unstable FPS's, going anywhere from 300 to 20 in some games.
Most crashes were solved by uninstalling the Gaming Evolved APP ( Raptor ), but recent titles such as Rainbow Six : Siege and COD: AW still crashed.
I tried several different drivers with no success, before having to upgrade to Windows 10 and doing a fresh install of it on the new 850 Evo SSD.
After updating Windows 10 and installing the latest 15.9.1 Beta driver, I noticed my FPS were much more stable, but I still got the driver crashes in the same games I previously had.
I tried changing to the Stable driver, and the problems persisted, so I contacted a friend that has far more understanding of computer hardware than I do.
He had me downloading the MSI Gaming App, which didn't work ( something about the platform not supporting this application ).
He then had me downloading MSI Afterburner, in which we ran some tests and eventually "fixed" the problem.
The default values were "Core Voltage : 0", "Power Limit : 0", "Core Clock : 1040", "Memory Clock : 1500".
At first we lowered the Core Clock to 1000 MHz, which seemed to solve the issue if I ran the games with nothing else open, but if I had, for example, OBS recording they would eventually crash.
After many tests, I ended up increasing the Core Voltage by small increments, noticing that it took longer for the driver to crash each time.
I left the Core Voltage at +25 mV, and keeping the Core Clock at 1000 MHz, which has so far proven stable and I'm yet to get a driver crash under any circumstances.
I now ask, could my card be defective?
Could this be solved in the future by a vBios update?
The computer shop I bought it from replied to my email, similar to this post, telling me to RMA the card, saying they had no previous complaints of the model, despite me seeing so many people with issues in these forums and throughout the internet.
Did this solve the problem for you?
Thanks for reading, I hope this topic helps.
