Re: POWERING RISERS USING 8PIN TO DUAL 6+2 PIN REMAINING STRANG FROM GPU
Thanks guys for the responses, despite the fact that most are in response to the other person. 
I've seen the shared chart with maximum wattages a few times and I know I'm not exceeding them. But here's the question:
Is the load evenly distributed across each cable, or is possible that the GPU may overdraw from one cable and not the other?
So if my 3080s are each hooked up with two 6+2s, and one part of that cable powers the riser, is it possible that the card will draw most of what it needs from just one cable, thus potentially overdrawing the cable?

POWERING RISERS USING 8PIN TO DUAL 6+2 PIN REMAINING STRANG FROM GPU
Hi everyone,
I've followed all the advice on how to safely set up PSUs and power your GPUs to ensure there's no fire hazard. However, I can't find definitive answers on a pretty simple question in ANY of the articles or videos.
I am running RTX 3080s, and they require THREE 8pin connectors from the PSU. The PSU supplied cables have 8-pin to dual 6+2 pin Y cable. As a result, two cables are needed to power a single GPU, and we have FOUR 6+2 pin cables from them. However, we only need 3 to power the GPU, so can the remaining 6+2 cable that dangles off to the side be used via a 6-pin female to 6+2 male extension to power a riser?
Thank you so much for clearing this up.

Received an Aorus Extreme 3080 - it throttles if it goes above 53-55C, dropping as low as 65mhs, but generally floating around 70mhs. Setting fans at 100% and opening the window helps to bring it back up to 87-95mhs. Generally avoid this card, despite it being the top tier card from Gigabyte. They're all terrible for mining it seems. Mind you, I run on VERY conservative +800mem OC.
The 4 MSI Suprim Xs I have are OK. 8 GameRocks are most consistent, albeit they run hotter than most.

I suppose you're speaking to those with 1-3 cards, how are we supposed to watercool entire rigs?
Updating the thread:
MSI Suprim X: Have 2. One will cause a crash at more than +1000 memory, hashes around 92 only. The other one is perfect at 99-100mhs, 35-40C on 1200 memory -500 clock, 60% PW 60% Fan
Palit Gamerock: 6 of them in total, all run 98-101 at 200W, by far the best card for mining. +1200 mem, -500 clock, 60%, 60%

Are both suprim x on the same bios ? I’m planning on making a 6 gpu rig with all suprim x . Don’t tell me they don’t all hit 99-100
I did not play around with the BIOS, I assumed I just didn't get lucky with the 2nd one. They can push to 99, but I'd rather prefer stability over the extra 2-2.5H. Running them at 96 and 94 respectively.
Updating everyone on the results after updating to HWinfo 6.42:
GPU temp followed by Memory Junction Temp:
GameRock: 66C, 96C
GameRock: 63, 98
GameRock: 55, 92
GameRock: 66, 106!?
GameRock: 52, 88
MSI Suprim X: 40, 90
GameRock: 43, 76
GameRock: 62, 94
Is this expected? Someone mentioned that the temps aren't for actual VRAM here, but reflect something else entirely? Im worried this isn't normal?
As for my room temps, it's around 20-25 I imagine. I dont have a thermometer here unfortunately.

I would like to add the following information to help with the thread:
MSI Suprim X does not throttle. Varying 97-104mh/s with +1200 memory -400 clock, 70% power, 70% fans.
EVGA XC3 Ultra Gaming - Does not throttle. Same settings as MSI above.
Will be testing the following over the coming days:
MSI Gaming Trio
Palit GameRock, 3 units (on this thread it was mentioned it doesn't throttle, so fingers crossed)
MSI Suprim X (the 2nd one so will be able to validate with confidence)

MSI AfterBurner 4.6.2 is too old, get the latest Beta for the RTX 30x0 cards.

These cards need to be kept cool to get the most out of them.

The gaming X doesnt seem to be suffering from thermal throttling cause it won’t even get enough power to get there . Also theres a butt load of thermal pads between the board and backplate .
I got the msi afternurner and even with maxing out the core voltage the card refuses to go above 88mhs . Soon as the memory goes over +400 the base clock drops to 940 and so does the hashing .
Right now when mining card is never above 45C
It's not the GPU core, it's the memory that's the issue, it's getting too hot.
Need to feed the card cold air to cool those memory chips down, not the GPU core.
The temp your seeing is for the GPU core at 45C, the memory will be in the 75C + range which is too hot, the card will throttle down based on this.
This image was taken from EVGA's overclock util, the card used here (RTX 3080 from EVGA) for this has the 9 extra sensors for the memory and VRM's.
See how hot the memory chips are above the GPU core and the lower right memory chip. This is the cause of the cards throttling down.

Could you please tell me which model EVGA you have? I've tried the X1 software from EVGA and mine isn't showing VRAM temps.
Hi everyone! Thank you for taking the time to provide insight into this.
I'm fairly new to the mining world and just started out with a small 5 GPU mining rig consisting of 3080s. I mine using NiceHash that mostly chooses the Hashimotto algorithm as most profitable. Currently, each card makes about $8 or £5 a day in profit. It's all very promising and great, but then I became aware of the ETH shift to PoS from PoW, thus making mining on Hashimotto obsolete/less profitable?
I am struggling to consolidate what the market or experts say will happen to ethash based algorithms and the profitability of mining on them. The timeline seems to be everything from a few months to at least a year, perhaps a couple until a full switch to ETH 2.0 is completed. Some suggest that ETH 1.0 will live alongside even after the 2.0 launch and the mining will remain viable on 1.0
I am not very knowledgeable in this, so I would be very thankful if someone can provide their insight who has their ear close to the group. Things I am trying to determine are:
1. The longevity of mining on Hashimotto algorithms or any algorithms on the ETH 1.0 network
2. The estimated timeline for a full switch, should PoW become obsolete after the switch
3. The viable alternatives mining outside of the ETH
Thank you so much for reading, and thank you for your help!
