Title: My rx460 Sapphire 2gb 2 fans version only has only aound 260Mh/s, what's wrong? Post by: j2ee on December 01, 2017, 05:43:48 PM I see people saying their rx460 can provide 300 or more Mh/s. I have tried both cgminer and bfminer giving me around the same 260Mh/s hash rate. So is this my card problem or something about setting? Thanks.
Update: A screenshot for you to have a look: http://oi68.tinypic.com/1z1wbvq.jpg Title: Re: My rx460 Sapphire 2gb 2 fans version only has only aound 260Mh/s, what's wrong? Post by: Vann on December 01, 2017, 05:46:46 PM 260 MH/s on what?

Post by: Vann on December 01, 2017, 06:03:36 PM Mazacoin is a SHA-256 coin. SHA-256 hasn't been profitable to mine with GPU's for years. You need an ASIC miner to mine SHA-256 coins. Even if you were able to get 1 GH/s you would lose money trying to mine it with GPU's after power costs.

I am mining Nyancoin which is Scrypt, but still around 260 hashrate only. Title: Re: My rx460 Sapphire 2gb 2 fans version only has only aound 260Mh/s, what's wrong? Post by: Vann on December 01, 2017, 06:37:30 PM Scrypt ia also an ASIC only algorithm for years. I would suggest downloading the NiceHash legacy miner and running the benchmark. That will tell you your rigs hash rate on various algorithms and then you can use whattomine.com to see which are currently the most profitable coins to mine with your cards.
https://github.com/nicehash/NiceHashMinerLegacy/releases You will likely find Ethash coins like Ethereum or Equihash coins like Zcash are your best option. Otherwise the NiceHash miner will also automatically mine the most profitable coins for your rig and pay you out in Bitcoin once you meet the payment threshold.

Thanks for your suggestion but I am wondering why my card is not at over 300 hash rate. Title: Re: My rx460 Sapphire 2gb 2 fans version only has only aound 260Mh/s, what's wrong? Post by: Vann on December 01, 2017, 06:51:33 PM You need to research and try out different core and memory clock overclock settings for your card to maximize the hash rate on the algorithm you are mining. With some memory intensive algorithms like Ethash and Monero you also need to Bios mod the memory timings on AMD cards to maximize their hash rate on those algorithms. In addition with the RX 460, you can try unlocking the shaders to see if it boosts your hash rate.

In CGminer, even I increase intensity, the hash rate is still the same... Title: Re: My rx460 Sapphire 2gb 2 fans version only has only aound 260Mh/s, what's wrong?

Post by: Vann on December 01, 2017, 08:00:30 PM Like I said, you need to research the best core and memory settings for your card. Maximizing the hash rate for your card involves lots of research and tweaking for the coin you are mining.

Post by: j2ee on December 17, 2017, 05:41:08 PM seem like almost no one mines with rx460 2gb so no one knows...
