when i first bought my xfx 390 DD i had some issues with my cpu heatsink and as my games started to crash i tho its was due to overheating, so i cranck the fan speed to 100% to keep it cool, after i bough a new cpu AIO cooling, i put back the fan speed on auto, and the crashing started again,even tho the temperatures were normal, so i started looking online for answers, i didnt know the 390 had issues with drivers/crashing, when i found this thread, i started some testings. first thing i did was putting back the fan speed to 100% and there we go, no crashes again everything working fine, i play GTA 5 and Final Fantasy Heavensward, so i did some testing
with fan on auto:
GTAV = crashed
FFXIV = Crashed
with msi afterburn keeping fan speed on par with temperatures
again crash on all games
so i put msi to put the fans @ 100% as soon as it hits 50*c temps and there we go again no crashes so far yet. so if anyone else willing to try see if this temporary fix helps them too
my comp spec are
amd FX 8320 @ 4.0ghz
MSI m5a97 r2.0 mobo
HysperX Fury 8gb(2x4gb) 1600mhz
XFX 390 DD with 15.8 Catalyst beta drivers
both games running @ 1080p full max settings
I will try this out tomorrow (with the fans running at 100%) although I cannot imagine why DX11 in Win10 would suddenly work just because the card is running a little cooler.
Mine on auto never gets over 73 C which on a high end GPU running flat out is very good and safe. I have a slightly tweaked fan profile that keeps it just under 70 C and also nicely cools the VRAM by over 5 C. At these temps my fans are around 53% of full rpm.
Just a thought for those having issues with GTA V, try running it with the command switch -DX10 or -DX10_1 and see if it becomes more stable, doing so forces DirectX 10/10.1 mode.
Note that DX10 visuals are inferior to DX11 so expect that, report back what the FPS is like. I do not have the game yet so cannot try it myself.
See this page from Rockstar for more command line switches, there are a lot of them.
