Could run down to -150c with pcie gen 2, memory seemed to scale negatively with temp. 1250 Memory timing strap. Could run 1800 mem at ambient. Vcore was around 1.55 but tons of black screening, didn't have time to do pex mod. memory stock 1.6v my other cards with elpida didn't seem to care for voltage at ambient. Had horrible negative eff as I kept rasing core clock, Asyq ran into the same issues with the same drivers. Something is def wrong.
