Hi! I’m posting this since I wasn’t able to find a similar case.
I’ve built a rig of 5 RTX 3070Tis from Zotac and no matter the settings I use I keep getting lhr locks.
I’ve tried those settings, 800 cclock, 1000, 850, you name it.
On memory OC just left it at 2000.
On a side note, the best result I had so far is with 800cclock and stock mclock with 45Mhs. But I was getting better results on windows although it was a bit unstable
From what I’ve gathered I need to look for a specific version of hive and miner.
On my founder edition 70ti I have around 41-42°c on the core which means mems should be around 88-90°c
For sure non-fe cards are better but not A LOT I think, looking your 60° on the core you may have very high temps on mem.
Try one of them on windows to check it out
