What happen to my GTX 1080ti I'm getting around 3.53 fixed mining almost 8 hours but I got huge hashrate drop almost 50%?
What happen? The gtx 1080ti is in GPU 0?
this happened to one of my 3 card (1080ti) rig, using gminer 1.23, other 3 card rigs works fine..
i put the card in 2 card rig, the card now mines at ~6.9, maybe due to cooler area i placed it in...i noticed that although the gpu core is lower in temps compared to the other 2 1080 ti it simply throttles down from ~6.9 to 3.6 after a few hours...leaving it for now since it is doing ~6.9 in the 2 card rig, will investigate in the future..
i'm suspecting it maybe is throttling down due to heating of the VRMs...happend to one of my 390s back then, don't know if 1080 ti do this too...notice the power is ~240+ watts, that's heavy on the VRMs
edit: it still go down to ~3.7 in the 2 card rig..i think it is a card issue
Celeron? You may be CPU bound. Otherwise lower your power level to 70% or so.
socket 775 xeon x3220 rig where i found it, i have same rig with no issues and i have even a lesser q8400 without issue...currently it is in a phenom x6 1055t where the issue reoccurred (but not persistent as in the previous rig), lesser athon x3 don't have issues too..it is not a cpu triggered issue based from comparisons.
it works at ~6.9 now, after i restarted it and it is running for hours now, something triggered it to run at ~3.6..thinking of heat still(since it is in a cooler location now), will clean it and investigate thermal paste and pads in the future..
here is another weird shit hehe(different rig), a 1080ti card don't want to mine with other 2 1080ti i thought it is defective (replaced it with another card rig works), and then i let it mine as a single gpu on a separate rig and it worked and i added another one (the ~3.6 one when issue appears)after i find it stable..so far they are stable mining as a 2 card rig..from what i observed in msi afterburner, although all cards are set at default and at 80 PL, that particular card clocks a little bit higher..
note: all cards are of the same brand and model.
