Not strictly related to this topic, but the AMD Linux driver must handle voltages differently than the Windows driver.

 

My Fury X is running a custom BIOS with voltage set at 1.3v.  When I was running it in Windows I had to bump the voltage using Trixx an additional +31mV to stay stable in [email protected]  Running in Linux I am 100% stable on the same BIOS without any additional voltage. :D

The OC on my Fury X hasn't really changed since I got it.  I did go through some odd stability and throttling issues that turned out to be borked drivers. 

 

I'm always looking to squeeze a bit more out of the card, and it looks like the move to Linux is a nice little bump in production. ;)

Just a little update.

I have now been running my FuryX in Linux for about seven weeks, and there is no doubt that the performance in Linux has now surpassed Windows.

Here is quick comparison of some of the different tasks:

p11432
Windows - 5 WU avg = 555,418 PPD
Linux - 5 WU avg = 671,890 PPD
*All tasks Run, Clone, Gen are Run=3. Run=2 seem to be even higher PPD, but I did not have any Windows tasks to compare to the Linux tasks.

p11713
Windows - 5 WU avg = 442,213 PPD
Linux - 5 WU avg = 523,918 PPD
*No discernable pattern in different runtimes/ppd based on different Run, Clone, Gen.

p9431
Windows - 5 WU avg = 374,957 PPD
Linux - 5 WU avg = 399,981 PPD
*Runtimes were a little closer on these smaller tasks, but the Linux tasks were still quicker than the Windows tasks.

p9415
Windows - 5 WU avg = 322,756 PPD
Linux - 5 WU avg = 332,297 PPD
* Similar to p9431 the difference in PPD on the smaller tasks is not as large.

With QRB the larger tasks serve as a very good example of how with QRB, the faster the tasks can be completed relative to the baseline, the higher the points awarded will be.
