Like all my other post about Crimson drivers 17.5.1 aren't any different. I can't use Wattman on my second card.
Describe your system:
- 2 x MSI 390X running in crossfire (Well when it and if it works)
- Mobo MSI Gaming 7
- 8x2 16Gb G.Skills Ripjaws
- Windows 10 64bit up to date - Clean install within the last two weeks.
- Current driver 17.5.1 and had issues with Crimson 16.1.1 through 17.5.1 - How hard is it to support your products.
- Antec 900W PSU
- Two ASUS MX279 Monitors running 1920x1080
-You can reproduce it just by installing the drivers and trying to use wattman, cant' enable, or disable except in Battlefield 4 & GtAV. Doesn't matter what Crimson version..
-One card always reaches 94° when I actually get CF working. It doesn't matter if I switch cards PCIe slots. I understand that one card will run hotter in CF, but one card runs at 72° and the other at 94° and starts to throttle back because of it. I expect a 10 - 12 degree difference, but not over 20.
-Relive Icon flashes and affects the playback, it's choppy and skips frames like it's turning on and off this issue with the latest two driver release 17.4.4 and 17.5.1.
-Escape from Tarkov doesn't use GPU fully or Crossfire. During game play my GPU only hits 582 Mhz..
-Roll back to 17.4.3, 17.4.2, and 17.4.1 still does the above. No improvement. 17.3.3 work better, but have CF profiles even though CF is enable the game isn't in CF.
I purchased a new case thinking it might be my case. I went from a AzzA Solano 1000 to a Rosewill Thor V2. I even removed the HSF on both cards and applied Thermal Grizzly Kryonaut.
Both cards are fine tried individually.
Please don't suggest I only need to run a single card when Sr.VP of AMD spouts off about running dual 480's keeping up with a 1080..
Never had issues running in CF on my 4870HD, 5870, 6970, or 280x. The issue all started when they released the Crimson drivers.
