My Gigabyte 3080 drops hashing after mining for a minute or two.

Tried changing risers and power connectors to no avail.

I have Silverstone Platinum PSU 1200 W.

The hashrate drops on both everything stock and TDP at 80 or 70 or any other value as well.

I have the same issue as you, with an RTX 3080 Gigabyte Eagle OC. Starts out at 88Mh, slowly dropping to 77Mh.
I installed the GPU straight on the motherboard. I noticed that the reason for this is that the core clock is dropping automatically to around 1000Mhz for some reason.
Also, total power consumption according to Phoenix miner is around 200W. (same thing with Claymore btw)

Did you find a solution for this problem? Thanks

okay there is no solution. the caps are a poor design and they cause memory to overheat.

what can you do?

downclock

and jack the fan.

set fan to 85%
set tdp to 65
set ram freq just under stock
set core to 900

you will get about 80mh but power use should be a lot lower. 175 watts

if you can manage to blow air with a fan on the caps in question do so.

come back and let us know what these settings do.

once cards are in stock say jan or feb turn it back for a rma as the new ones should have better caps.

which caps are you talking about? Why would the caps only get hot while mining memory intensive workloads?
The card doesn't throttle on benchmarks even while hitting core temps of 70+

memory frequency the higher it is the more it stresses the cap designed to filter noise etc. noise make heat.

so yeah better thermal pads help somewhat but multiple cap designs tweaks to multiple frequency points will help. since setting ram to a lower frequency does not ruin warranty do it. and the gear will be better.

it should help you understand the safest temporary fix for a shit card like the gigabyte is clock the ram lower

and rma in jan or whenever they fix the cap patterns

Yeah I knew about these cap issue but internet mentioned they weren't as bad as originally thought they would be.
Anyways I've ordered some thermal pads will see. My plan was put some near the memory chips are between the backplate and pcb. Can check if the caps could be given some thermal padding too.
