This makes me REALLY interested to see how performance will be affected once I finally get my 3090 out of my old i7e 6950X system and into my Ryzen 9 5950X system.No shunt mod? Push that sucker to 450w.
Anyways with new 3960x, found out that turning off SMT makes a huge jump in performance in TimeSpy for the EVGA 3090 XC3 Ultra with Threadripper, this is with stock GPU settings. Also system memory speeds also has a big impact on performance. Anyways this is a comparison of before and after with no OC on the 3090, all stock settings and just changing system memory speeds from 3200mhz to 3733mhz and turning off SMT. Impact is huge!
