Got some new ram sinks on, and stuck the original cooler back on (its actually not bad with a little help from an 80mm)
Card runs with a few artifacts in drago hi @ 337.5/702 which isnt bad. vGPU is 1.9 and vMem 2.92 IIRC. Gonna whack the vGPU to to 1.95 ish and shoot for 340 stable, then work on the ram some more
