Claymore's ZCash/BTG AMD GPU Miner v12.6 (Windows/Linux)

[Golku]

Need some advice

I need a couple of new cards i can get these 2

280x for 115 usd
470 for  220 usd

The 470 sounds like more future proof but getting like 180 sol
280x looks much better it can get like 210 sol

Ok, so it looks like everyone else is getting approximately the same hashrate difference for R9 390 vs. RX 480. I get 260 H/s and 190 H/s respectively with mine (both 8 GB). So my question is, is it expected that the 480 hashrate is only 73% of the 390? Is it because of the lower power consumption on the 480? With every other miner/currency so far, my 480s hash at about the same rate as my 390s. Is this something new with v8.0?

No it is not. It is because 290/ 390(x) are high end cards vs 470 low-mid/ 480 mid level, amd has not released that high performance gpu yet.

470/ 480 owners were lucky to enjoy hig end hashing rates at one algo with some bios modding. Today ancient 290 hashes more than 470/ 480 with the same or better hash/ watt ratio, better get used to it.

ps. what where those every other currencies where 480 matched 390?

ETH and SC

Try 700/750/800/850/900/950/1000 // 1000/1125/1250/1375/1500.

-100mV is a good starting point, this is not some king of voodoo magic, this info has been floating around the net for years.

Guys show some effort, from your posts it looks like 480 can do what 150s/ 110watts?

Certainly better to take new cards from three-year warranty, I think card Rx series is the best choice now!

It must be, just do not whine on claymore's thread.

I have few rx470 from xfx, the single fan ones, and with 1500 straps bios mod and clocks: 1200/1000mv 1750/1000mv they are doing 173h/s at 127W from the wall measured with smart plug. This is with V8 and -i 4 setting. This xfx model is the cheapest but it's very silent, running at 70C with 35% fan speed, the room temp is 25C. The nice thing about them is dual bios

R9 vs. Rx has it's pros and cons,

RX
-lower power consumption
-One 6 or 8pin connector
-higher resale value
(CONS)
-slightly scaled back hashrates, especially at stock bios (modding the bios voids warranty)
-expensive

R9/HD 7000
-higher hashrate
-high bus width (384 and 512 depending model)
-generally less expensive
-fantastic if you have free electricity.
(CONS)
-harder to source
-likely less support and optimization moving forward
-probably used (and abused) for up to 4-5 years.
-takes up as much power as a stovetop
-hot as a stovetop
-as heavy as a stovetop
-not a stovetop.

So much wrong in this post.



R9/HD 7000
- Better price per hash
- Much better build quality compared to most RX series GPUs
- Never have to worry about melting SATA cables since they use max 20 Watts from PCIe slot compared to 100 Watts like the RX 480.
- Already ROI'd for most
- Use a little more power but it shouldn't make a difference since your profit is much much greater than your electricity cost anyways. If the 280x is too costly for you to run, so will be the 470 and you shouldn't be mining anyways due to your electricity costs. The difference is maybe 5cents daily on 10c/kwh power.
- End of depreciation curve. Pretty much won't depreciate 50% like the RX series. Buy today, mine, and sell in 1 year for almost same price.
- Much more stable AMD drivers. When a GPU hangs, it doesn't freeze your entire system or BSOD.
- Doesn't require HDMI Dummy plugs.
- Easier to use in Linux due to temp management
- No stupid RGB LEDs which are crazy annoying at night and pose a security risk.
- Southern Islands Architecture is more geared towards GPU Compute rather than Polaris which is more geared towards gaming and VR.

Only con I can think of is due to the Tahiti's bad speed in ETH. Hawaii is still fine.

Now this is some valuable information, thanks for posting this!

What is this smart plug?

[Alehandros]

did someone have more than 189 h\s on ref rx 480 8Gb?

yep getting 200 from all of mine (see earlier post)

Hi All,

I've just created a page where one can share your experiance with your graphical card in order to have a benchmark.

Of corse I'm using Claymore since beginning and v8 works perfectly ! Thanks claymore for your job and effort ... waiting for version 9 ... 10 ...

waiting for rev, after I sent the info... really?

I'm beginning to believe my motherboard is not capable of handling more than 2 cards ugh! Msi z170a gaming pro carbon either on boot (windows 8 or 10) doesn't recognize cards, afterburner doesn't show temps and card crashes or opencl hangs on miner

I heard that chipset Z170 causes problems with more graphics cards for mining (in concretely following motherboard: https://www.asus.com/Motherboards/Z170-PRO/). However, I can not guarantee that this is true. Maybe someone colleague miner has experience with chipset Z170.

It's rock solid for 2 cards just no more :/

Edit: finally got both my 380s and a 280x running both 380s are mounted on motherboard with a riser plugged into the other x16 slot ...trying to use any of the X1 slots causes instability and can't use more than 3 cards (I'm hoping for stability with these 3)

where is the bios switch on those all my xfx dual dipass i cant find a bios switch same with gigabyte g1

You should also include a power usage field - - for instance - "Watts at the wall". This is 50% or more the decision factor for buying GPU's when miners have to pay for the electricity to power their rigs. Not just Hashing power.

Other considerations - Overclocking fields and memory timing straps field - etc

Just my 2 cents

[dextronomous]

Hi there, Mr. Claymore,

could you maybe or not,

the fans are checked when they got the fan speed reported right, can this be disabled,

one gpu with rpm different then the other same card with different rpm on the fans will not get to mine,
or crash, it mines all other coins,

i found out it has to be the fans, fanmin 100 fanmax 100 just wont fix it for me, they are in overdrive at 100% or automatic, but one of those fans is connected with 2pins, and gpu caps viewer shows 100rpm on that gpu, thats why i have to be able to skip this fan check somehow, could this be done with V9?

all versions on this card could not mine, at all. the other same cards will did do work fine as should.. thanks a lot again.

I got a Z170 board not knowing issues.  It will see and mine with 4 GPUs no problem (470/480), though if you try 5, it will lock up at bios, even though board has 7 slots. I have http://www.newegg.com/Product/Product.aspx?Item=N82E16813128838 Then I just decided to get H81 BTC pro boards (harder to find).

This MSI Z97 works just as good as an H81 BTC - cheaper in most cases - plus it has 7 pcie slots - I have 2 rigs with this board and 7 RX480's each. Works great.

Claymore,

Are you ever planning on releasing a version of this software for Linux?
