I just set up my rig as a proof of concept before I dig i further. I started with 2 Zotac AMP! Extreme Edition 1080ti cards. I’m running them on an ASUS Prime 270a, with 8gb ram and core i3. I’m using the newest version of EBWF and mining on Suprnova. My drivers for the cards and the Bios on the Mobo are both up to date, and I configured the Mobo with the settings suggested in the video everybody likes to bandy around (Gen2 etc for all the relevant PCi settings, and 4g Encoding is Enabled etc). I’m running Windows 10 as well.
When I start up the rig and start the miner, I get around 765 sol/s for both cards, but it quickly throttles GPU0 down to 265 sol/s where it remains indefinitely. What’s going on here? GPU0 is not overheating, MSI afterburner is telling me it’s sitting at 44C, so it’s not throttling due to overheating…
GPU1 which is getting 765 sol/s is running nicely at 65C.
What am I missing here and what settings should I change to get full performance?
Additionally, my PSU is an evga 1600w, so there’s no way power supply is a concern either, I’m sure it’s some mundane detail of a setting or something that I’m missing.
Also, I’ve got the cards set to factory clock settings in Afterburner.
