saw a few people sell their cards from etherium mining. says non LHR. didnt know a thing about lhr till a few days ago. yea im not in the know of hardware. how bad can it be?

Im not a heavy gamer, but im guessing components may have been beaten. vrm, capcitors etc. but does it always mean "dont touch" ? ive held each gpu I had for at least 8 years. and they work fine. im sure mining is like 8 years in1.

guy is selling a 3080 pheonix 10gb for $285. says you can come over and stress test it no problem.

arent these higher end card good quality to handle heavy work?

just curious and keeping options open as I look for a gpu to upgrade rx590.

I bought Dell RTX 3080 10GB used for mining before. Heatsink is rusted. It lasted about a year and a half before it died, from what I checked one of the PCIE 8-pin is shorted.

shame. I take apart my gpus apart right before summertime. winter it runs without any issues in the cold. blow it out with a blower every 6 months. +/-

I regoop repad, I use caig pro gold. use a toothbrush to scrub the whole board. and obviously spray down the cooler. abou an hours work. my 9800gtx still runs. I also make sure to clean behind the fans where it spins. there it can fail with the turning area. spray the hell out if it with caig pro gold.

JUst saw some videos regarding purchasing mining cards. seems ok. ask the seller, stress test, maybe buy new fans for it. also spray down the pci slot on the mb and the power connections. obviously let it dry before assembly.

"should" be ok.

is furmark the better program to stress test a gpu? 5-10 minutes is enough?

I've purchased a lot of former mining cards on the cheap. $80 RX 580s prior to the pandemic and gave them out as gifts to people who wouldn't be able to afford a GPU of that power otherwise.

I've had one mining card fail after about 3-4 years of use (not on me, it was one I bought for someone else). In all I'd say that's a good track record given the quantity purchased. The failure rate has been lower then that of new cards I've purchased although it's not a statistically significant enough quantity for either to draw actual failure rate conclusions.

I did have one mining card that had bad memory out of the box but that was a easy return.

The primary problem I see for mining cards is fan bearings going bad. Not too hard to replace them usually though. Cards used for mining are almost always cleaner than cards used for gaming. IMO seeing a dirty mining card is a red flag that the miner didn't take care of their cards and I probably wouldn't buy mining cards from a vendor that just let their products run in nu-monitored conditions for months while dust gathered. Particularly when mining cards can be used in locations where there is less protection swings in temperature / humidity.

Caps do have a finite life and a well maintained mining card will have less remaining life as compared to a well maintained card used for gaming. Key word is well maintined.

I bought Dell RTX 3080 10GB used for mining before. Heatsink is rusted. It lasted about a year and a half before it died, from what I checked one of the PCIE 8-pin is shorted.

Rust on the heatsink likely indicates either the card was exposed to excessive humidity or salty air (was housed near a body of salt water and was exposed to the wind). I would have returned that card the instant I saw it.
