Hamster this is fully dependant on AMD supporting these features for these cards. Right now overclocking doesn't work for many users.
Thanks for the answer Mat.
I am afraid it is never going to happen when it didn't happen since loosing those features over a year ago (loss of bezel compensation) since the Crimson driver take over. :-(
For anyone who is using this
18.2.2 on a nMP with 2x D500 AMD GPUs with crossfire and eyefinity:
- install the latest MSI After Burner
- check every single [√] option in the general menu (most importantly shutting off ULPS mode) and reboot
- then gradually overclock
I am running a rock stable overclock for years @ 975/1350 with crossfire for years in games (stock is something like 725/1025 or thereabouts).
The performance difference between stock clock speeds and this overclock in games is immense (stock being completely useless in any modern games).
My nMP showed instability when going further above that overclock by simply freezing and rebooting. There were no other signs of instability like artifacts or visual anomalies - it would just freeze and Windows reboot.
If that happens, dial down your overclock (I saw a bigger impact on stability on dialing down the memory clock while this also had the least penalty on performance, hence I came up with the above clock speeds for the D500 GPUs)
With any driver revision update the key is to follow:
- wipe clean all driver remnants in Windows OS safe mode
- install new driver (I always skip the AMD Relive install option as it has given me lots of headache in the past)
- install MSI AB as described above
- experiment which MSI AB settings lead to stable, proper use of BOTH GPUs in crossfire mode (this is the major issue with AMD driver revisions as with the newer drivers the GPUs will momentarily switch between power modes erratically leading to heavy flickering and screen tearing and stuttering often combined with erratic crossfire GPU utilization)
- only when the above runs stable, overclock and if successful, STICK WITH THAT DRIVER for as long as you can
A word to other overclocking / tweak tools:
In the past I had good luck with using ClockBlocker for disabling ULPS mode.
I also had some good experience, tweaking certain driver settings with a tool called RadeonMod (find it on the Guru3D site), including disabling ULPS mode.
Since the Adrenaline driver releases I found both these tools were providing no good solution regarding the ULPS mode power state switching and resulting screen flicker / tearing.
I recommend EXCLUSIVELY using MSI After Burner.
You loose the individual driver setting tweaks (which cannot be accessed through the AMD driver software) but it is the very only way I got the ULPS mode issue fixed and gotten a stable overclock in crossfire on triple screens.
Hang in there with your nMP trash bins guys ;-)
