Informative video, But 1. Shouldnt we start with FurMark first as it is an holistic test? and then go to the nuanced test as mentioned by you? 2. Also if a card is mined(without us being aware) but its under official warranty and we have the bill, Can we get a replacement(Within the 2-3yr warranty period it has remaining)?

[@TechLens]

Honestly, you can run them in whatever order you like 😊 that doesn't matter too much. Good question, I've heard stories of companies refusing the warranty for mining. But realistically, there's not going to be a whole lot they can do if you just say "it has never been mined on", even if you don't know. Best thing to get is a cash receipt from the buyer if possible. If they paid by cash, you have the original receipt and there's nothing linking someone else to the purchase. You're golden. Got an amazing deal on some memory a while back. 1 stick was completely defective, but they had the receipt. So I bought it and did the RMA myself and was super happy.

[@jakthebomb]

I bought 2x 3090 Founders Editions that were mined on. I changed out the thermal pads and paste the day I got them. Dropped the VRAM from its normal 100C down to 80C. The Card was clean with no dust. With no adjustments, the clocks stay stable at 1950 Core. I have put at least 100 hours on one of them, and 500 hours on the other. Zero issues.

[@LanaaAmor]

did the miner overclock it or did you underclock it? Also isn't screwing with the settings risky? pls give more tips

[@jakthebomb]

@@LanaaAmor I didn't touch any settings, replacing the Thermal Pads on the VRAM chips is what allowed the massive drop in temps. Both of my 3090s are still running solidly.

[@LanaaAmor]

@@jakthebomb how do u replace it? does it help in performance or make the card last longer?

[@jakthebomb]

@@LanaaAmor There are plenty of guides available online. Recommend Gelid Extreme 1.5mm Thermal Pads, the Ultimate stuff was too hard. The idea is that stock pads have the VRAM running close to the limits of GDDR6X's thermal limits. The new pads bring that down comfortably within spec. This in turn would prolong the lifespan of the card. The 3090 has had a few cases of VRAM chips fail prematurely.

[@LanaaAmor]

@@jakthebomb but isn't it the actual graphics chip that fails usually? Also is it beneficial on used mining cards like 1050ti ?

If it'll take that much money then you shouldn't be buying those cards in the first place tho. How crazy are your prices ☠️

[@rowd8343]

A while ago (when the mining was still peaking) i heard about a tool named MATS MODS. I remember that the tool checked the memory corruption in the graphics card. So in that way you can test which memory module is good or broken. (Which is a main component that is used while mining). And then, you could replace the memory (via microsoldering) and that’s it (i think).

[@MaxC_1]

MODS = Nvidia Modular diagnostic software is actually the main diagnosis program while MATS = Memory Automated Test System is the standalone version which only checks for memory errors and such

How did you get through your GPUmemtest, it doesnt show openCL for my rx 6800

[@chincemagnet]

Personally, I don’t recommend running Furmark, except for short term testing. If you don’t know what you’re doing, don’t touch it at all. It’s more likely to explode your caps and cook the VRM, or pop a fuse on that card. It’s more of a power virus than a gaming workload. I’d recommend, and this isn’t free so I guess thats why he doesn’t recommend it, is 3D Mark stress tests. Just leave one of the Fire Strikes, or Time Spy running on a loop. Each test has different properties that push the VRAM, and pushes higher or lower frame rates. I’ve had very good results that are reliable with that.

the best video about checking both used GPU i've seen. GJ - subscribed to you because of it. Both month ago a used 6700XT, will test it like you just did.

[@solaraspect5255]

Great guide, apart from one thing. DO NOT just use FurMark willy-nilly as a normal lay-user. The application is meant for experienced overclockers who know to manage performance and temperatures. If you use it without the proper cooling, it is simply a frying simulator, where you need to turn it off before your GPU reaches 100 degrees C. I did a test where my GPU reached 110 C and then shut down. Thankfully no major damage, but I can't recommend this unnecessary step to anyone else. Can you run the newest games for hours on end whilst also having photoshop or blender open in the background? And all of this under 80 degrees C? Congratulations, you passed. Furmark is essentially a boasting benchmarking tool for measuring you know what replacements. The practical use for the average user is limited, when compared to other more reasonable ways of benchmarking. I can run Skyrim with 1500+ mods ENB 2K textures and everything else cranked to max with 115 variable FPS (I lock to 61 for stability though). Baldurs Gate 3 is a stable 144, and Elden ring max settings I get 95 FPS. I also use VRAM heavy tools in the background at times. For me there is no need for any further "stress testing" - these scenarios simply don't exist. Games that use 120 % of your clock speed should be illegal, and I haven't tried any either. No game engine starts out with a mission to destroy GPUs, in fact the opposite is the goal.

[@JustMyFish]

A card that has been mind on for two years, is under a constant load at a steady rate so there is no thermal throttle they are generally undervalued and kept in dust free environments. So in most cases. In better condition than a card that has been played on heavy and overcooked for two years. It’s been proven many times that mining is less stress on the card by around 10% so it’s better to buy an ex mining card than an ex gaming card.

[@thebritishviking]

Exactly; Under constant load. The fans will go first. The memory can only handle so many reads and writes before those modules die.

[@rezkinapitupulu6606]

it's gonna be lit when I'm opening a spreadsheet in front of the previous owner like a mad scientist

[@dancotton13]

Usually a slight memory overclock and test will reveal if the card was mined. The miners do that memory overclock in order to gain more same time underclocking and undervolting the GPU in order to get more efficiency for the power consumption. So the first clue is an instable memory or memory crash when you overclock it. The memory chips do get damaged and "older" with frequency increase and high temperature.

[@fr0stief0n]

I purchased 3 rtx 3070's for 300 each. I'm happy with my savings and performance. My home is now equipped with 3 great gaming pc's for about 800 each, or the price of one new high end pc. If the card have made it through 18mo of full use. They'll be okay for gaming, apply new paste and ride.

To bad GPUs dont have a SMART. chip or something in the hardware like a Hard Drive has so you could see how many hours were on the card.

I purchased (by accident due to the ad changing daily) a 3080ti off Amazon. So far so good. Cards been preforming well and benchmarks above average but I'm constantly worried about it breaking.

[@chincemagnet]

Always test any component prior to maintenance or modification. New cards these days, decent ones, not Dell or OEM reference garbage cards. Newer cards come with good paste and pads from the factory. You’re more likely to make things worse, you’re better off leaving it alone unless there’s an issue. Almost killed a brand new 3090 applying Kryonaut, only to discover there’s a good chance it came with Kryonaut from the factory. So I messed something up that was shorting the cooler off of the PCB, by over tightening, and got extraordinarily lucky it didn’t kill it. It just wouldn’t even recognize the card and the bios is like beeeeep x5 times, which often times indicate a bad connection or electrical issue. Had it happen again recently when a fan wasn’t plugged in completely. I did get a 1080 with the cooler not installed correctly from the factory. So that was a necessity

Mining requires underclock not overclock, specially the gpu. As for the memory depends on what coin you are mining, some need a bit overclock and some don't, and others need to lower memory so gpu can work better. I have been mining since long time and my cards are all the AMD from Sapphire and temps are below 50celsius. So why you trying to make some people get frightened? For example Raven coin you need to underclock the GPU by 20 to 25% less. It gives same hashrate as normal clock but consumes less power and gets cooler.

[@bonhomie6275]

I use my card for both mining and gaming, mining at lease giving you back some money and won't be a problem if you manage the temp well. most of the time my card sit at 65 C when mining. Not noticeable. No performance drop either as when you mine crypto, you underclock and undervolt the card for better heat management, not overclocking when when they work 24/7. CPU mining is also a thing, nothing smell so good than OC the cpu and it still run at 50 C while mining with 15% improve in hashrate.

Here in the US, those stickers are worthless. You buy it, its yours, and you have all the rights to take it apart for any reason. Manufacturers cannot deny service for breaking a sticker. The owner has to drive a screwdriver through the pcb or something for warranty to be voided. Also about fans, don't freak out if you buy a used card and the fans don't work. Clean/oil them because the owner could have been a smoker, and that gpu sitting around unused can allow the tar to congeal effectively acting like a glue.

I definitely, well, I suspect I got a couple of mining cards. I assumed when I bought them they were mined on. It’s pretty obvious when a seller has multiple of one type of card. The Zotac 2080 was a blower style, a bit of dust in it, nothing crazy. It turned out even though the power limit was gimped from the factory, that card ran like a beast. My Dell 3080 on the other hand, it was near spotless. Obviously disassembled and modded for improved vram temps. And that card runs like crap! There’s nothing wrong with it, it’s just so pathetically underpowered, it can’t even maintain 1 volt under load. It works great, it’s just a very bad reference model. Wishing I had spent an extra bit of money and got that used FE. The point I wanted to mention was one of the fans bearings was on its way out. It would make this crazy rattling sound at around 60% fan speed. I liquid cooled it which helped immensely, but the VRAM still cooks for some reason. Crappy water block, Alphacool Eisblock, I took one look at it and was like, I haven’t seen a water block this poorly designed in almost 10 years. It was cheap, got the card and built the loop for under $600. I think it needs a better pump, I got a 360mm rad for $45, and a Chinesium pump and reservoir for $25. Works better than I thought, not as good as I’d hoped. Core temps around 50C, VRAM still in the 80’s though, which is HOT for liquid cooling.
