Topic: Any ALGORITHM that Supports OLD GPUS??? (Read 310 times)

lyclminer will do lyra2rev3 on pretty much any old GCN and pre-GCN AMD card, lyra2rev2 was break even during the big boom a while back on my 6870 even, you'll lose a bit now unless you have free power.
as for nvidia.. well, I don't think you're going to have much luck with anything prior to Maxwell, nvidia stuff wasn't great for mining in general before it. Maxwell (the 750 Ti specifically and the whole 900 series) isn't that obsolete, a lot of stuff will run on it fine. With 2GB of VRAM a few ethash coins should fit and run "efficient enough" but not very fast, a little better on linux. Some of the x16r miners probably support it, not sure if it's too late to get in on progpow for BCI but I've tested the ethminer fork on maxwell cards before, I would expect phoenixminer's support of it to work too.
expanse and ubiq are 2 ethash coins I've run on AMD 2GB cards recently. I think ubiq might have some customizations to the algo, but phoenixminer supports it, haven't looked too far into that detail.

edit: for old GCN hardware, my HD 7850 was able to get 17.9MH/s on SMOS mining ubiq. Callisto is what I used to mine on it, but it seemed the 1.75GB DAG wasn't fitting into the vram anymore, even on linux. the same card maxed at 10 at stock on windows, 14 With a high OC.  17.9 on ubiq with 120-140W is below break-even for me. R9 290s get about 30 on linux, but they have 4GB of vram they can mine etc and eth at 28-29MH/s and that has higher revenue. My kill-a-watt died so I can't measure them now, but I'm assuming at -very- high power. I don't have other old hardware like HD 7950 or 280Xs to test.

The point is, he's trying to make money with what he's got. It's a fair question.
@Ddante, the short aswer is no. These old GPUs are not efficient enough, and support has mostly been dropped by all new miner devs.

Its obsolete.
1060 6Gb would be a start.

This is a useful topic for me as a beginner in mining. I have an old PC with GTX950. Is there a chance for this card or it is obsolete like the car the topic starter owns?

I had a Radeon 6990 and the coins you can mine were limited about 2 years ago... today there is probably nothing out there you can mine.

Reason being is that AMD stopped developing drivers for the Radeon 6xxx in 2015. While the Radeon 7xxx is still being developed in 2019. The last coin I could mine with the 6990 was XMR but they forked to a new algo, no idea if the current algo would work. The software is limited.

So like the above poster... you need to get some decent hardware, you can get an RX 470 for like $75 these days.

algo is the the same, just your old gpus are not efficent anymore. Waste of time and engergy...

if you want to have some experience and learning with gpu mining
then the cards you have will be a good starting point
once you understand more of the mining you can invest money for a better rig
but do not have any hope of earning money with these cards
i guess you will be losing money in electricity

Agreed. Everything is old, the HW, the miner and especially the algo,
meaning there's probably an ASIC for it by now.

Why continue mining with this hardware ? Low hashrates for high energy !

Is there still hope for old GPUs ? All my mining rigs are built with old amd GPUs and old nvidia GPUs ,i find it hard to mine monero because of the updated algorithm and new miners dump support for old GPUs ,is there still any algorithm I can mine with old GPUs like gtx570 ,hd6790 basically terascale and cuda8 ?
