Constant 11.++MH/s

Was hoping to get 15MHs unfortunately averaging about 11

Running on an
CPU : i5 2300
RAM : 8GB DDR3
HDD : 120GB SSD

Temperature : 75

Will be returning this cards and get RX 480 instead.

I am currently running dual RX 460 on a rig and to my surprise I have been getting a constant 23.xxxmh compare to my single Rx480 where it spike from 15.xxmhs to 40.xxmhs.

seems the RX 460 gives a more stable output.

I'm glad I didn't purchase a RX 460 then, 11MH/s is not very impressive considering the RX 470 is not much more expensive.

I havent tried 470. Likely i will return the 460 for the 470. My 480 is giving me around 23 to 26. If 470 can give me 21 then i will switch all to 470 i guess....

Your 460 had 2GB or 4GB RAM? I'm guessing 2..

I was anticipating this one to hash at 13MH/s out of the box with half the memory bit lane while slightly higher on memory clock speeds vs. the 470. And 15 MH/s OC


You mean to say a single RX480 gives you a few fluke hashes at 40?

2GB or 4GB RAM?

It's 4gb... At this point I don't think it makes much difference between the 2 or 4

I would say my fluke is about 15 to 20% of the time. But I have low at 15 at times. 460 deliver constant 12.xx and which makes me feel that this card is greatly hold back and that's why it can drive a constant MH where as 480 is push to certain aspect.

In consistency I mean 98% of the time

If you are getting 11-12MH/s that is to be expected with the memory on the RX 460 you would have to get over 2000Mhz to get to 14-15 MH/s with an RX 460 and who knows if you will ever be able to oc your memory that much.  Also since their isn't a reference RX 470 at the moment for $150 your choices are really the RX 460 or the RX 480 4GB version for mining.  AMD is messing with the driver at the moment to by limiting the overclocks on memory, which is a change in the 16.8.1 driver release but only for the 480's, imo to protect the RX 480 from the RX 470 which holds basically the same performance as the RX 480.  The RX 470 was a terrible release with no reference release cards at all so you'll pay the more or really the same as an RX 480.

I paid 180 for my 4GB Red Devil RX 470.
I think prices will come down in a few weeks once everybody stocks up and the release craze is over.

 HD 7870 manages about 11 MH/s - and costs a LOT less usually than an RX 460 - but DOES eat more power.

 Looks like the RX470 or 480 (depending on what price you can get each at) is the new "sweet spot".

That one is the only one I say that wasn't really overpriced and that is only because of the cooler that PowerColor decided to put on it but I think the ref. blower is fine for the RX 470.

Did you OC the memory on the HD 7870 cause my HD 7850 does 13 MH/s and 12.5 with claymores dual miner with eth+sc

I'm pretty sure I have memory and core overclocked, but don't remember what settings I was using.
 I did NOT have the ability to undervolt that card, as I never found any LINUX-based voltage control software for HD7xxx series stuff.

 Academic right now, as the card got replaced by one of my R9 280x and is sitting in the box as a "spare" after the motherboard in one of my older machines DIED on me during the move.


 Other difference is I was using qtminer, I was never able to even DOWNLOAD claymore as the site they host on was INACCESSABLE where I lived before - I should probably try to do that sometime soon, though I'm FAR more inclined to go with Genoil as I HATE the whole "I'm going to use YOUR machine to pay for MY software" concept when there is a good TRUE FREEWARE option with competative performance.

I don't think he supports Linux anyway but I do agree with you in general about paying for the software especially since my hashrate is  so low that he can't possibly ever get a share for eth mining in the 72 seconds that he uses my machine in an hour.  I haven't been able to get genoil to work with my AMD 2GB cards, so that has also forced me to use claymores software.  I do like that I can mine two coins at once with little to no impact on my mining though.

I'm  getting a HD 7870 XT today so I will see how that does I'm hopping to get around 18-19MH/s  I saw a club3D card that was only getting 14.5 but don't really understand that as the memory was way underclocked they took it from 1500Mhz to 1050Mhz for Ethereum which is stupid.

I have the 7870 card. The most you will get is MAX 12.50MH/s. I currently get 12MH/s at stock clock/voltage. You can get like 20MH/s if you mine Expanse.

Its also horrible at most other algorithms and you can't dual mine really because it slows down the ETH speed.

But its uses very little power. Maybe 100watts or less.

The RX 470 is better if you can up the memory frequency to that of the RX 470 as not all cores are necessary.

What I'd like to get is the hashrate on other algorithms than Hashimoto. I near don't care of this one.

On the 128 bit bussed 950 and 960 nvidia cards I use -farm-recheck 150. with oc I can push them to 13mhash ech.

Might worth a try on the 460

I can confirm that assessment of the GTX 950 but its only possible in Linux now cause of the messed up drivers in windows  :(

The 7870 is a Tahiti LE core not a Pitcairn XT core  and the 7850 will give similar results with ETH as the 7870 does as it's tied mostly to memory speed
Model:  PowerColor PCS+ HD 7870 MYST. Edition

 1500 is NOT stock clock on any HD 7870 - they predate memory that COULD run that fast "stock" by 2-3 years.
 1050 though is an oddly excessive underclock, perhaps that was misreported and was the CORE clock.
 1500 didn't become stock clock on any AMD card I am aware of prior to the R9 3xx series.

 18-19Mhs out of a 7870 is NOT a reasonable expectation, don't think they mined THAT fast even the first couple weeks Ethereum existed and had much smaller DAG file sizing.


 11 Mh/s is what I'm getting out of my currently-running 7870 (I forgot I had *2* of those cards), running 950/1350 (ANY other mem clock speed gives slower hashrate on this particular card, higher core clocks give NO hashrate improvement and make the card run hotter).
 That's on a Sapphire "reference" design card that has a MAXIMUM memory OVERCLOCK of 1450, and stock 1250.
 That IS running qtminer - genoil or claymore would probably add a couple percent from what I've seen on comparable testing, if I could ever get one of those two downloaded AT ALL.

the sapphire rx 470 is 199.99 at newegg there is a coupon for 15 so it is a 185 usd card  and does 21.5 to 22.5

15 dollar coupon is you spend 200

card below  is like a reference it is 199.99

buy two and take off the 15$ coupon   you get 43mh and spend   385

    you simply can't get a   rx 480  which will do 24-26 mh  for 192.50


the 460's suck  11-12 mh  a pair at 23 mh   cost was 300 for 2

I think you are confused with the 7970 vs the 7870


All 7800 are Pitcairn.

I just got in two of the MSI 4 GB RX 470's to test with, and I can confirm that out of the box you get 20.5 MHs at default settings.

The memory clock on this particular model is 1650, but I have already successfully increased it to 1850 and am getting another 1 MHs (21.5 MHs) stable.

I also tried clocking the memory to 2000 (which does bring it to 22 MHz), but it crashes after a little while. I need to play around with the other settings and voltages a bit more to make it stable at that speed, but I have hope.

Also the power draw is about 110-120 watts per card. For now I am happy with the power draw and might even give it a bit more voltage to stabilize at 2000 memory for the 22 MHs.

yeah my 470 sapphires are close to you.  so far thumbs up for the 470 and thumbs down for the 460

Yeah, I am happy so far. I would like to get a bit more out of them (steady 22 MH/s), but for the price and power draw it is pretty decent. Also once the demand cools off a bit, these should drop another $20 to $179 or so.

how you measure the power draw? at the whole PSU?

Sorry for your confusion but here is a link to the card.  I'm kind of a hardware nut and usually look for things like this.

 Not if you run Win7 - all of my 950 and 960 cards work fine in Windows under 7.

 They're NOT trying to run the "latest" drivers though, since those drivers are all about being able to use GTX 1xxx series cards.


 I had a 7850 mining ETH for a while, but it was partly damaged and I was never able to run it even at STOCK clocks, so it's MH was kinda low.

problem here..
I have rig with 2x RX 470 and I got one RX 460.. problem is that I only get about 2000 mh/s with RX 460, while RX 470 (moded BIOS, OC) giving me normal hashrate (28 mh/s)...

where did I go wrong?
RX 470 are connected with risers, RX 460 is plugged directly to MOBO...

Connect monitor to GPU with low hashrate.

 There were *2* versions of the 7870 - the original that was Pitcairn, and the "7870 XT" that was Tahiti (seems to have been a cut-down Tahiti chip with 1 or 2 CUs disabled).
 Arguably the "7870 XT" should have been named the "7930" or some such to avoid confusion.


 Turns out my 7850 wasn't broken - it was the PS I was trying to run it on was broken.

A 1050 TI can do 12-14 MHs. They are reasonable if you catch them on a sale.

it did not help
anyone else?

What is the hashrate of unlocked 460, with modded straps?

how many watts you spend for each?

thank you

RX 460 for 89 is a BUY   ZEC ONLY ON THIS BUT STIILL

Is it late to buy a rx 460 2gb? Whats about the hashrate?

You can't mine Ethereum with any 2GB card.

But you can mine other algorithms.

Thank you! One more question, are the benchmarks at monerobenchmarks.info authentic?

The Sapphire Radeon RX 460 provides hashrate of 11.5 MHash/s for Ethereum at Coreclock 1216 MHz while consuming 40 Watts watts.


 Gpu Specs

I used a special video card processor patch just the same for RX series graphics cards. Got a significant increase in speed. If you're interested, I can share this with you.

The mod to unlock shaders? (896 to 1024)
