So finally my Build is complete and I would like to show it to you guys.

Tuned my GPU over the Weekend and I would say Results are fine. No hard OC just easy Tune .

Raised Powerlimit to 133% and Core Voltage to Max just to make it safe . Heat is no Issue for this Card .
Hotspot while Gaming is around 60-65°C while GPU is at 50°C .

My 270k Plus runs 5.7 Pcores and 4.9-5.0Ecores .
Ring 4.0Ghz . Because I run my 8400Cl38 I don‘t want to Stress the last bit out of NGU and D2D.

For RAM I just used a Gigabyte Hynix 8400 Profile with loose timings and tightened them a bit . Also Trefi is set to 263k.
Tested with Karhu, Anta777 and more over multiple Nights(30ish Hours) and it works for the last 2 Months.
