Mining with "obsolete" graphics cards (memory<2GB)

[666mrga999]

This thread is for miners with older cards that can't mine ETH or other "mainstream" coins anymore.
I was wondering if anybody has any ideas what coin to mine for miners with GPU memory 2GB or less. I would like to use my prehistoric 5850s again. Discuss

No point in mining with them unless you have free electricity. Most miners are optimized for GCN cards (7700 and above), so 5850 will not even run or have terrible performance.

The best for AMD cards HD5xxx, HD6xxx or others with 2Gb or less vmem is cryptonight alogorithm (XMR - monero) with Claymore CryptoNote miner 9.7.
Quote from readme:
"This version is for recent AMD videocards only: 7xxx and 2xx, also 6xxx and 5xxx. No nVidia support."

ZEC, XMR, ZClassic, or possibly ETC (I think the DAG file for ETC is still small enough to allow mining on a 2GB card).

 All of my 77xx/78xx series cards have been on ZEC (or working GRC via the Moo Wrapper project) for a while but I've been looking at XMR (my pair of GTX 750 Ti have been on XMR for a while because they're incredibly efficient at that compared to almost any other card on a hash/watt basis).

I'm mining lbry with good ole sg on a r7 200 (270) 2gb card havin a blast and don'the give two flying f÷%@KS what electricity costs . If I find more next to nothing cards I'll be tieing them in as well. Good mining

1 GTX 960 2GB here and several CPUs.  Electricity is included in my rent, so why not flog some older hardware.
I used Nicehash legacy and Nicehash 2.0 rediscovering mining after putting it down in 2015.
The best algorithms for the clock rate and ram available I discovered was:
1. X11 Gost alexa ccminer windows.
2. Neoscrypt via excavator windows.
3. EWBF z-cash miner to nicehash at 170-180 sols/sec (windows) It will run on a 2GB card.
4. Cryptonight via xmrig which take less than 1GB ram on the card to 1.6GB if you go large on the processing array. I am getting about 270-280 H/s at 1495 Mhz , 1024 CUDA cores.

coins 1-3 vary depending on the earnings converted to BTC. Nicehash legacy shows you the rate based on it's benchmark.
coin 4 Stays in the middle on return for time.
However, nothing stopping you from investing in mining your coins on pools to hold the exact coin, but you have to install a wallet for each type of course.
Typical earnings I found was 0.69 to $1.40 a day with nicehash. However, I am banking Cryptonight on a different pool for investment purposes. For the long haul.

For the Nvidia 9xx Maxwell cards, get the techpowerup Maxwell II BIOS tweaker to set your fans, boost, and p0 table for overclock a bit.

cheers.

Two R7 260x OC here, with further overclock by me, using MSI Afterburner. Both have 2Gb of GDRR5 Ram and as you've said yourself, you cannot use them for Ethereum Mining.
I'm currently using Nicehash Legacy, however, quite a few algorithms do not function, they crash the drivers, no matter which version I'm using.

I have managed to get reasonable earnings by mining with the Equihash algorithm, now earnings have dropped dramatically, it will only spike every once in a while and that's it.
I suppose you could try mining other Ethhash coins, like MusicCoin, (Was less profitable than Nicehash Legacy when I tried it) or mining other Equihash coins, such as ZenCash.

i have my useless cards 6xxx mining xmr at miniingpoolhub and then switch it to btc

[BHTeam]

you can mine HUSH once ETH is no longer an option for those cards.

Is it possible to run more then 8 "obsolete" AMD GPU in one rig? I am running 4x HD6990 in one rig, Windows 10 Pro, Crimson 15.12 driver, Claymore Cryptonight AMD GPU 9.7 miner. Every HD6990 GPU contains two Cayman GPU, so system is up to it's maximum Windows capacity of 8 GPU, modern drivers that remove the limit do not support HD6990. I try to find mining Linux version but so far can't find any supporting Cayman. Please advise what OS may be appropriate for the task.

There is a driver specifically designed for mining. They are not very critical to the equipment. The installation of these drivers will help you. I have the same driver works AMD 7990 and RX 580. Try to contact the support NiceHash. They spetsializiruyutsya in such situations.

There is absolutely no point in doing that - even if you score and mine a coin which will skyrocket,
that means you'll be earning $100 per year, instead of 10...

4 x HD6990 keep $10 a day. Not bad at all for obsolete hardware.

That is pretty awesome and also is nice to see the reuse of older hardware instead of just going into the EOL bins as is the case with most cards under 3gb these days.

100% agree with this no point to mine.The electricity have to be free if you need some profit with old gen cards.

No info from NiceHash support. They offered to read FAQ once more, no useful info in it.

Do you have some real experience or ever try to calculate expected profit for HD6XXX cards?
My hands-on experience prove you are wrong for HD6990. Maybe it's the only exeption, don't know for sure :-)

PS 0.05 $/kW|hour cost for local electricity

Older GPUs need to use Nicehash legacy. Latest clients do not support older GPUs

NiceHash Legacy is Windows-only up to date. Still need Windows driver. So we are again stuck with 8-GPU maximum for old ADM drivers (ex latest windows driver for HD6990 by AMD is Crimson 15.7).
