Riding the Crypto wave

[TheoneandonlyMrK]

Plus they do tend to be cooled better than a lot of normal system built cards ,my two main pc gpus are not hitting more than 47° and they have been running days at an overclocked level.
Even my r9 390 is downclocked slightly to keep it at 70°.
Spent ages last night fitting an evga 460x 2win in my main rig ,turned to shit though, the second gpu on it has a faulty cooler attached (i tried reseat and retim a few times) and hits 100 in a minute even downclocked to 500mhz the first was fine so i disabled no2 and cracked on , except it sounded like a large plane landing and I couldn't sleep with that much racket , ive decided i too need a room for this stuff but i gots no room.tut.
It was also a bit shit at hashing but its old , soo a 5850 , what would that do dya reckons.

So equihash seems the most profitable on my 7950. I get 13mh/s in Ethereum, gets 290 sols/s with equihash which is 3.70-3.80 a day. It roughly equals my 1060's in equihash lol

Interesting my 7950 does only 250 sols/s. At what clocks is your card running? Did you try mining expanse? I get about 19.5 MH/s on it. With this Zcash and Expanse net the same gross

My mod BIOS is 1150/1350 1.3v, I have downclocked it due to the case running a bit too hot like that (850/1250 now which is 220sols/s) and when I get them moved to a rack I will bump them back up. I actually had to drop the clocks on the 1060 as well, might have to add another pull through fan on this one. I have not tried expanse yet.

I dont use myetherwallet anymore since I lost 4 coins in there. I send my coins directly to Coinbase wallet.

Is that mean i will newer get out 0.01770 ETH Is there any point to use dwarfpool, nanopool, miningpoolhub or suprnova, coinmine.pl How they work?
Claymore gived me two freazing sreans. i get 11 Mhs
I need to calculate all the expenses then problably mining is not worth it.

Damn! There are going to be some good deals to be had on GPUs when the markets crash!

Yep, I love it when the coins rally and when they crash. On one hand I make money (did it in the last rally with a 7970) and on the other hand I get cheap cards to expand my army of F@H/BOINC cards. This time, looks to be both AMD and Nvidia cards. Hehe, can't wait for some cheap RX580s to show up later. Want one to fiddle with.

Cards can take some serious abuse. That 7970 is still alive from doing over six month to one year of mining, then 24/7 folding, then boincing. And, that stinker was on air. Tanky little card for sure. Can't complain about trading it off for a motherboard last year.

 

[silkstone]

Define a "good deal". Is it really a 6-month-old GPU with a "mileage" of a 4-year-old card used for frequent gaming?

There aren't any mechanical, moving parts and are quite robust. I've had gaming cards die after a year not mining and, like other people say, some cards that have been mining for years are still in good working order. Personally, I'm keeping my 1080 underclocked and at 85% TDP. The temps never go above 65 C. I don't think people running them in farms would want them overclocked too far either as it just makes more work for themselves when the cards go down.

Yes. I could kick myself (gain). I've known about ETH for well over 2 years, but I never bothered even looking into it. I was kind of pissed off at missing the bitcoin surge and decided to totally ignore crypto until now. Big mistake. Just a year ago, when I was running a 7970 xfire system, I could have been making 2 ETH a day! I keep missing the real rallies.

I wish I still had my 8 7950s I sold back in 2013.

Too bad.

I'm starting to regret selling my 1060 that I let go to an ex-student for very cheap yesterday.

Claymore sometimes goes up to 89 C, recomended for card is 80. Need to increase fan speed.

Yes. I Wouldn't be comfortable keeping any card that hot 24/7. Even my old, HOT HOT HOT 9870XT is kept around 75 C for 24/7 use. I'm in no rush to burn out my hardware when I don't really have the means to replace it right now.

Are you sure?
If I were you, I'd wish I sold my 8x 7950s and bought BTC.

There aren't any mechanical, moving parts and are quite robust.

1) Obviously, cooling is mechanical (usually).
Check the MTTF rating for your model (if you can find it), but take it with a grain of salt. Some manufacturers will show over a 1M hours here, which is just pure rubbish.
MSI rates their Core Frozr (CPU cooler, possibly similar to Twin Frozr in MSI Gaming GPUs) at 150 000 hours... at 25*C. This will drop severely when working at constant ~70*C.
2) Electric parts wear out as well and once again: costant ~70*C will not help.

Yes, the fans will die sooner, but I don't have much luck with fans anyway. My 9870 fan died in less than 2 years and I have a cupboard full of old broken case/cpu fans.

It is a bit of a gamble. I am hoping the either mining will stay profitable for long enough, or prices will rise high enough, for me to at least make the money back on the GPU. I'm not worried about resale value too much as I'll likely just cycle it through computers. I wouldn't really worry about buying a ex-mining gpu either, assuming it was still in warranty and the price was right.

 

[FireFox]

How much would that card make per day

Joke

 

[silkstone]

@cdawall Do you encounter any more problems in you AMD/Nvidia mixed rigs? I am thinking about putting my 7870 in with my 1080, but I will be away from home for a month and so crashes will be quite hard to deal with.

I do have a VPN set up to my network for remote admin and I have my bios set to turn the computer on at a certain time (in case of power cuts). But any fatal errors would mean a month with no mining.

@cdawall said in post #156

Mixed is fine. One of my best miners is a 980ti, 1060 and 1070 in one box. Uo until last night it had a 290 as well.

 

[silkstone]

@cdawall said in post #156

Thanks. Yeah, I know that they will work together fine. I'm just double checking that there are no issues with disconnects, etc.

I think I will just move my 7870 over tonight and check for the next 3 days.

In my country i think i can get only back 20-40 euro what is spent afterwards for electricity whit one rx460 11,8 Mh.s if i mine ETH all month in a day.

What country do you live in and what is the power cost there. And those rx460 and rx560 are really bad cards to mine with.

107.37 KWh is 21.89 EUR one mor 145.00 kWh 25.29 EUR Latvija
They also no good for gaming not much games to play especialy whit old cpu.

 

[hat]

Looks like I can get a whopping 50 cents per day with my 660 Ti...

I guess RX580 would be nice to have?

60MH/s in ethereum with a 1080...wonder what they did to "tune" it. I am hoping it is a driver thing that I can push into my cards.

 

[Ithanul]

Holy...darn that is nuts.

Though, I wonder. Can those cards fold or boinc?

I really cannot imagine that they would perform worse in those apps.

Hmmmm, I going to keep an eye on these. Hehe, I can see some very cheap cards later on. With no video output, I can see these going for super cheap later when peeps try selling them off.
