Expand memory tweak to GDDR6X (RTX 3080/3090) #164

Closed fynxer closed 3 years ago

fynxer commented 4 years ago

Do memory tweak for GDDR6X (RTX 3080/3090), it seams nvidia is a bit restrictive with memory timings so it could be worth investigating if GDDR6X timings can be tweaked to increase performance. Seen on forums that Chinese miners got +100MH on 3080 by tweaking so it seams to be a possibility for at least 10-20% extra performance gain.

It is working on my rtx 3080 without any problem... not probably 100% optimazed but it is working

Mining is all about profit, more hash rate with lower power consumption equals more crypto for less money.

Optimizing by strapping GDDR6X could possibly yield another 10-20% hash rate.

You are already doing it with GDDR5X so why not try out GDDR6X optimization.

If it works well this miner software could start a new mining wave for the nvidia 3080 and be the goto miner for 3080 rigs.

It's not allowed by Nvidia's driver anymore, for newer GPUs.

There is a way to do so, even adjusting the core clock is possible.

GDDR6 optimization (without the X) would benefit series 20xx cards. Really hoped to see that happening!
