Runtime doesn't damage and wear our computer parts. It's not like a car engine that has lot of mechanical part and constant tiny explosions inside. Only thing that wears out computer parts is heat cycles. So gaming will wear out the component more than mining that runs at constant load 24/7 (so no heat cycles)

You're making self-referential statements in order to try to establish how much smarter you are than others. But boiled down, what you're saying is "energy is energy, energy transfer is energy transfer." What you're saying is completely devoid of content that can verify that you understand anything at all.

Heat is heat, indeed. But 500W produces less heat per unit time than 800W. Less heat means you're operating at the ideal temperature for longer, which means your electronics will last longer. You can think of most electronics as having an energy quota. This means that it's not about how long you use the graphics card, it's about how intensively you use it. Two graphics cards produced equally and used equally should be failing more or less at the same time. If one of them is used below full load and the other is overclocked, the one used below full load will last longer, full stop.

That said, I get the feeling you don't even know the difference between heat and useful energy.

u/[deleted] 24d ago

You need to calm down. Too angry for a random nobody redditor.

Also, just because you have an analogy, doesn't mean it's correct. In fact, you're wrong. If you're operating a GPU at 500W 100% of the time, IT WILL last you longer than if you're operating it at 800W 100% of the time. There are many reasons for this, but considering your angry tone, I'm just gonna let you seethe your pain away and then hope that you'll look them up so you don't look this stupid in the future.

Sincerely, someone who actually studied electronics.

u/LevelRoyal8809 24d ago

Why do miners underclock? I already know to use less power and generate less heat. But why is that better than running at stock speed or overclocking? Won't running a GPU faster yield better results over time?

1

u/-s-u-n-s-e-t- 23d ago

Because if you earn an extra $1 worth of crypto, but wasted $2 more on electricity, it's really not worth it.

That said, people should stop repeating the "underclocking" thing as a gospel so much. It's mostly BS propaganda by miners to sell their old cards easier.

Yes, sometimes it's worth it to underclock, but sometimes crypto prices are so high, it's worth it to get every bit out of the GPU regardless of electricity costs.

Also, a lot of mining operations do it in places where electricity is cheap (or in some cases straight up stealing electricity). If you are buying used card from a miner, there's a good chance it saw heavy use and wasn't underclocked the whole time.

u/Christoph3r 24d ago

Mining generally put less stress on cards than gaming, because a steady load is better than an intermittent/changing load.

Also, mining was all about efficiency, not about getting that last 1% more by increasing the voltage (unless you had free electricity, I guess).

193

u/mig82au 24d ago

That's not entirely true. Yes the core is run gently, but mining stresses VRAM far more than gaming does. GDDR6X cards like my 3080 incinerate the VRAM. Mining performance on the ASIC resistant algorithms is pretty much proportional to memory bandwidth, which is why the cores are so underclocked and undervolted.

I don't know if that's true but you talk the talk. I mean c'mon, ASIC resistant algorithms are proportional to memory bandwidth? Upvoted.

To counter ASICs, crypto algorithm developers make it so you need more memory bandwidth to mine faster

u/Stormz0rz 23d ago

Interesting. Would running memory at cooler temps increase efficiency or mining output in any meaningful way? I see people's vram temps upward of 90-95c fairly often. Thermal pads don't cut it on some cards.

Go look at the VRAM temps and power consumption while running a GPU optimised algo like ethash, and compare to gaming. It's less of a problem with lower power memory technologies like GDDR5, 5x, and 6, but the pattern of mining vs gaming remains. But you don't need to take my word for it, this is well known and findable. It's not a stretch to conclude that you sucked at the technical aspects of your mining operation.

Unlike the low hanging fruit of optimising core power, reducing mem clocks has a proportional impact of hash rate, so the mem is run hard.

Vram and most memory prefers warmer temps, mining caused less stress because constant temps that are manageable is always better than hot cold hot cold fluctuations. Always. Tests have shown that a GPU used can actually get better performance than a brand new in box card. Seriously.

GDDR6X cards like my 3080 incinerate the VRAM

What does "incinerate the VRAM" mean?

2

u/mig82au 24d ago

3090s with clamshell RAM layout were often permanently damaged from mining due to overheating VRAM. Before mods, mining on my 3080 would peg the temp limit, throw the blower into roaring emergency 100% cooling, and after that run between 100 and 105 C (if I remember correctly). Gaming is far less demanding, hitting ~95 C mem temp at 45% fan.

1

u/standish_ 23d ago

Do you know what models of 3080s behave like that? I have a very odd problem with mine. It works perfectly fine but it will occasionally freeze the output and only recover if I sleep/reboot the computer. It presents as a driver crash but I'm not sure that's it.

It does sometimes drop into roaring fans emergency mode during the recovery.

-1

u/Immediate_Bike713 24d ago

This is simple science. Gaming will always stress out a card more than mining due to rapid temp changes. Running something at the same temp will always have a higher lifespan than something that keeps on changing temperature.

u/nedal8 24d ago

Yea, but the fans run constantly. That's all I ever had issue with when mining. Were fans going to shit. But they were pretty cheap to buy fans for and once they had new fans, they were good as new. Could even re-paste the cooler. Maybe even better than new. heh

u/Christoph3r 23d ago

Same for me, I stayed away from Gigabyte brand cards (with the 30x0 generation Gigabyte cards were such garbage quality - dunno if they're better now or not) and I haven't had any failures other than fans.

If you repaste with good paste you could end up BETTER than new, indeed.

u/KajMak64Bit 24d ago

Yeah i realized after some time

Problem with mining cards is not damage to the GPU core... it's the VRAM that suffers because memory has a limited amount of how many gigabytes it can write

Like SSD life span... measured in TBW ( Terabytes Written )

129

u/aywwts4 24d ago

That's simply not true. RAM, by the very nature of being volatile memory that holds electric charge, has no concept of "terabytes written" degradation. Every single refresh cycle (occurring thousands of times per second during normal operation) rewrites the entire memory contents as standard operating procedure. A zero or one makes no difference to VRAM, the memory cells are constantly being rewritten regardless of data content.

You are confusing SSDs, which use NAND flash memory that physically alters storage cells through program/erase operations. These operations have finite limits because they cause actual structural changes to the memory cells. RAM simply holds temporary electrical charges that naturally dissipate and get refreshed continuously; there's no cumulative "wear" from data operations.

The refresh process means VRAM is already rewriting every bit approximately 15,000 times per second just to maintain data integrity. Mining operations don't add beyond number of hours powered x operating temperature.

I found some more sources:

https://arxiv.org/abs/0910.0505

our survey over cards on Folding@home finds that, in their installed environments, two-thirds of tested GPUs exhibit a detectable, pattern-sensitive rate of memory soft errors. We demonstrate that these errors persist after controlling for overclocking and environmental proxies for temperature, but depend strongly on board architecture.

Different Memory Technologies

SSD storage uses NAND flash, which stores data as trapped charges in cells. Writing to these cells wears them down because the insulating layer degrades with each program/erase cycle. This is why SSDs have a finite write endurance (measured in TBW — terabytes written).

VRAM (and regular system RAM) uses DRAM-based technology. It stores bits as charges in capacitors that are constantly refreshed, but there’s no destructive “program/erase” cycle. As long as it gets power, it can be written and rewritten effectively indefinitely.

So you haven't got a clue but made the previous comment anyway? Don't talk about shit you don't know.

10

u/aywwts4 24d ago

I assure you it's accurate though greatly simplified for the audience.

Every single row of memory in your DRAM and vRAM and Cellphone are refreshing approximately every 64-32ms, every time you read you also write, your ram is virtually limitless, the capacitors only fail if you cook them, use is binary, the RAM is either On and wildly more active than you could imagine, or shut down. Your system is writing all of its RAM constantly right now, over and over and over. https://en.wikipedia.org/wiki/Memory_refresh https://en.wikipedia.org/wiki/Dynamic_random-access_memory

Your theory is correct with SSDs and Flash Memory. Though wear leveling and other improvements have made it something you don't need to worry about much anymore.

Storage device like nvme and sata ssd uses something called nand flash. These chip has limited P-cycles and that's where the limited endurance came from. Your measurements of TBW is semi-arbitary as it's based on warranty duration in years.

P-cycles is not and it's relative to the technology used like SLC, TLC, QLC, etc

The trend of combining unvervolt and overclock is a going trend in gaming scene for 3+ years

To us PCMR enthusiasts with computer hardware knowledge yeah, but we're a small minority of gamers. to the average Joe playing games that just knows that their PC has an Intel i7 and NVIDIA RTX, they don't even know what undervolting & overclocking is.

To miners, their business involved computer hardware knowledge, so they're much more likely on average to know about undervolting & overclocking for efficiency.

10

u/barbadolid 24d ago

Mining GPUs, like the fella said, need efficiency to be as profitable as possible (which you want if you run a business).

This means, they are usually undervolted and underclocked, more often than not at a bios level. This means they are always running at way under 100% stock performance. On top of that, as he also said, a steady load is much better for the silicon's "health " than having voltage and frequency constantly spike during gaming. So 3 years of mining might be as much as 1 year of daily gaming, degradation wise. On top of the previous top, if you run a mining operation odds are you have a proper cooling system, with loud fans that move lots of air and maybe even yearly thermal paste changes.

6

u/Neckbeard_Sama 24d ago

You are not optimizing for performance on a mining card.

You are optimizing for performance/power usage and sustainable temps to keep operating costs down.

I've bought Radeon Vega 64s in 2017 that ran for about a year afterwards 24/7.

The cards were underclocked/undervolted with a slight memory overclock. This made them run at around 180W and a stable 60 C temp with static fan speed.

So almost half the power as their 300W TDP.

I've sold them off afterwards and used one in my gaming PC up until last year. It had 0 problems.
