Info

Info & Hints:

Some Info: HBM2 Based GPU's do not need to be under load to apply timing changes. It is often better to apply new timings before starting a benchmark/mining tool. AMD Driver will reinit upon launching tool (especially for Vega)

Some Hints: Some timings are stability timings, lowering these will lower stability. Such as tRC. Some timings might require a higher value for performance to improve. Such as tREF. Some timings have a min/max value, going outside this range will result into it defaulting back to original value. Such as tCL Some timings are dynamic, they change based on the vbios values and active clocks. Dram timings. ...

Row Access Timings tRC, tRAS, tRCDRD, tRCDWR, tRRDL, tRRDS, tFAW, tRTP Column Access Timings tCCDL, tCCDS, tCCDR, tWTRL, tWTRS, tRTW, Refresh Timings tRFC, tRFCSB, tRREFD, tREFI

In the unlikely event of not owning either BTC or ETH and you do want to be an amazing person and tip, shapeshift, changelly, simpleswap, ... are great ways to solve that "issue" ;-)
