Micron garbage memory and the temp is fine, never gets above 55C. I tried lowering OC settings and it still errors out of EWBF. Its basically a worse 1070. My 3x 1070s are pushing +200/+600 no issues @ 70 TDP (and they have Micron mem as well). This 1070 Ti cant hold +50/+200 at 80 TDP for more than a hour maybe two. Hashrate is equal to or a little less than the 1070s. Disappointing.
Even tried putting all my 1070s on the risers and the 1070 Ti directly on the MB but still same issue.
Did you try overclocking them separately? It's always +xx/+xx @ xx TDP in your posts, so it's hard to be sure what's what. Set the powerlimit to 100, don't touch the core clock and simply increase the memclock to check the actual memory OC limit. Cause +200 max doesn't sound plausible, it should be able to OC more.
