hi,

summer is coming,
i have 4 reference vega 56 with stock bios.
In order to lower the heat and reduce the noise, what should i do ?
flash them with 64 bios ?
which ppt should i use ?

today, i use my vegas with stock bios and 1100MHz HBM @ 905mV power play table
and i have this perf

and 718w at wall

thanks fot help

I wouldn't flash to v64 because that increase the voltgae on the hbm and make more heat.
But you say you use stock bios at 1100hbm isn't that vega 64?

Anyway. Try and lower your core clock as low as you can tolerate the drop in hashrate. This will reduce power and heat.

i didnt flash my vega 56 but i used a ppt from http://vega.miningguides.com/#SoftTables

in gpuz, the default clock is 1408mhz and memory 1100mhz
clock 1400mhhz and memory 900mhz
