he is not getting performance he is simply killing his gpu.

at op

lower the memory clock

lower the power setting

get the 108c to drop under 99c  

work at that and get back to us.

Set the power to 225 or 230 not 250

set the ram to 1000 not 1300

see what happens

"The video card must be Rev 1.0 released before week 22 of 2021, the week and year of release can be found by the serial number.
Where the first two digits are the year of release, the second two are the week number. Videocards issued before this date are not LHR.
The serial number is on the box with the video card."

It depends on whether they are REV 1.0 or REV 2.0

Apparently REV 1.0 are not while REV 2.0 are LHR
But good luck getting the REV 1.0. REV 2.0 seems to be the type that if readily available

If you need to quickly connect 2 video cards and you need 5 connectors 4 x6 + 2pin PCI-E.
The power supply has 8 connectors for connection, but the specifications indicate 4 x6 + 2pin PCI-E and 2 x (4 + 4) 8pin CPU.
If I understand correctly, then 2 connectors are still free. You need another 6 + 2pin PCI-E cable.
Perhaps it is universal, and it can be used from other broken power supplies. Such cables cost 7-10 dollars.

2 3080s with a 1000W PSU is close to the limit. If you can't get good quality cables it makes a big difference.
That includes the cables that connect directly to the PSU.

Don't consider splitting unless you have an 8 wire cable with 8 pins connected to the PSU. Many PSUs come with
a mix of cables with either 1x8 or 2x8 GPU connectors. You can convert a 1x8 to 2x8 with a good splitter.

Also depending on cable quality you can convert a Molex cable to 8 pin PCIe, preferably use a 2xMolex to 8 pin converter
and 2 seperate Molex cables to better distribute the load.

Whatever you do watch for signs of overheating of the cables or connectors.

Your question is about an altcoin gpu miner and this is btc mining hardware area. I asked mods to move it.

But what comes to your question,
a good sturdy psu would be:

1x HP DPS 1200 FB A  (max. 1200 W at 230V, or 900 W at 110V) server psu
1x HP common slot psu breakout board for 12x 6-pin
12x good quality (6+2) -pin pcie power cables
1x pico psu for motherboard powers

This setup was roughly what I used for my previous gpu miner I had back in the days.

we are far from being in a bear phase i would say indeed that the bull phase continues in a great way the value of bitcoin continues to grow slowly, your cost of electricity is average so in my opinion you can safely continue to mine with nicehash you will surely be in profit

Yes, here's my comment.

Why do you want to mine in the bear market and not right now? What's the difference? If the price rises, so does the difficulty. If the bears come, the difficulty drops. You're incentivized to mine based on the profit you can have, but long-term, it's the same translated into a fiat currency, whether you're in a bull or bear market.

Short-term, you should prefer mining in a bull market.

Yes, its fine unless its a high power draw GPU ( in your case, the 3060ti's are safer to use with Molex powered risers than the 3070's, so use the 1 remaining pcie slot with a splitter to connect the two 3070 risers to them)


When using molex and sata, use only one strand per riser ( even if the strand has 3-4 connectors )


Your math isnt entirely accurate, risers dont always consume 75w thats generally the rated maximum. Figure out a way to measure accurate total power consumption at the wall where you plug the psu in (buy a power meter or use an household appliance stabaliser etc) for accurate measurement, and decide on PSU wattage accordingly. For your 5 GPU's, the risers should be consuming no more than 35-40W each, so the total should be 280W max for the risers, and 675W for the GPUs, making the total 955W which is dangerously close to the PSU's limit, and will likely cause failure in a few days of running. Also remember PSU is rated at 1000W on 240v, on 120v it can only manage about 750W.


No, every manufacturers cables may be different and its high risk. Stick to known brand PSU's like Corsair, EVGA, Antec, Coolermaster etc and make sure you get Gold rated or above. Thier product pages list all the cables they come with.

You would need to use 7 of the pcie ports just on the GPU's, so how are you powering the risers???
Splitters are fine to split ONE pcie port to two for connecting two risers to each, but anything more than that is begging for trouble.

Ideally you need to have enough pcie ports on the psu to power all GPUs and risers. In a pinch you can use molex powered risers, but do not use any molex-pcie adapters that come with risers, those are a fire hazard.
As a general rule of thumb, do not exceed 80% of the rated load on the PSU for long term operation, 75% if you dont have adequate cooling.

Buy 3 6600 xt at 500 each or less if you can.

I think that if you put the fan settings at 80-83% you should be Ok with this card as the cooling system of graphic cards has always improved and Rtx 3080 makes no difference.However check constantly the memory temperature which should not be higher than 100-104 degree celsius,not the actual GPU temperature as that should be always under 70 degree or max 70 degree if you are in a hot environment.I think you should be good to go with just setting the fan speed at the levels I said because I have seen a few friends who have 3 x of this GPU and they are running fine at 62-67 degree celsius with the fan set at 80% speed.

The type of memory these cards use tend to overheat easily if not taken care properly and the thermal pads are the same.The Rev 2.0 means it is a low hash rate card which means it can max do through NBminer which has unlocked these LHR cards to 68% which means the hash rate will be max 68 Mhsh compared to 100 Mhsh of the Rev 1.0 card which is non lite hash rate.Anyway still a great buy as you can mine ERGO and RVN with this card as the hash rate limiter is only for Ethash algorithm in Rev 2.0 while in Rev 3.0 everything is limited,every mining algorithm.It can work great as a gaming PC the combo that you have bought.
