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

[cashen]

The best drivers i used without issues is 16.9.2 , i installed it on all of my rigs months ago and updated all rigs except one still running on 16.9.2 and it's the best performing between all rigs no problems at all.

2 people recommend 16.9.2 Claymore  himself claim that 15.12

So that's why I wonder.

16.9 series do not require signature check bypass.

Often, when mining Ethereum claymore would hang after this

Catalyst 15.12 is REQUIRED for best performance and compatibility
At least 16 GB of Virtual Memory is required for multi-GPU systems
Make sure you defined GPU_MAX_ALLOC_PERCENT 100
Be careful with overclocking, use default clocks for first tests
Press "s" for current statistics, "0".."9" to turn on/off cards, "r" to reload pools
OpenCL initializing...

POOL/SOLO version

It just stuck there doing nothing. I wonder what the miner is doing at that time?

I havea rig of 7 470s which hang there for a good 60 seconds.

I have another rig of 5 480s and 1 470 which blows through that part.

Yes. But you may try to OC memory. Try memory clock 1501+MHz - will be next stripe. I'm use Asus 280X 1.1V 1100/1600 with modded bios, 17.4.1 driver Windows 10. 330 H/s on miner 12.2. 12.4 is unstable and each 1-1,5 hour hangs.
Default is 1.2V 1070/1600 without bios mod - 300 H/s.

P.S. In driver version 17.4.1 AMD adds wattman compatibility for 200-series cards. It's very useful, much better than Overdrive. But in 17.4.2. they disabled wattman and enabled overdrive again... It's strange... If wattman can work with 200-series cards as in 17.4.1., why disable him in 17.4.2...

regarding OC a 280. my 280 only responds to core clock. at default 900 mhz it hashes about 250 sols/s and at around 1100 mhz it reaches just above 300. Memory clock have little to none impact.

Maybe your memory is already very fast.

Stock 1200, but able to push to 1600! But no increase in speed

hello,

one question about mining zcash.
i alredy have 2 rigs (sapphires 470 and 480 8gb) and i am mining mostly ehereum.

i will like to build one mlre rig, more specialist for zcash. i will like to know what do i need to look on gpus? for ethereum i was looking more on memory, how is here.
do i need to buy 8gb or i can get 4 gb for the same hashing power? i know that nvidia is better, but it is also more expensive.

any advice very welcome. thanks.

If you mainly want to mine ZEC, it is better to buy the nVidia GPU now. For AMD, if you can buy old GPU, the R9 390 is good.

Depends on the price dif between RX470 4GB and RX 480 8GB. In most cases, % increase in cost is not justified by the % increase in performance. Except if you have a density problem then that offset the cost increase. All up to your numbers.

Best way is to work out for the same hash target. You will need 9 RX480 8GB rigs to match 10 RX470 4Gb rigs.

Cost of 1000W PSU
Cost of MB, CPU and RAM
Cost of 6 Risers.
Cost of the frame.
Cost of 6 GPU's

Get the totals and compare
6 x RX480 8GB 1830 sols/s
6 x RX470 4Gb 1680 sols/s

Why not 280x ? They have better hashrate/wattage ratio.

@topic
if i use "-nofee 1" will miner show real hashrate? i mean without those optimisation or it will lie?

Guys, windows detected rundas.b in this miner last friday.  Anyone else have this problem?

[br2459]

Anyone using MSI Twin Frozr 7970? I want to compare and see if I can get more out of it.

For Zcash the "best" option would be GTX 1070s.... if your budget permits buying the more expensive hardware at the start. If you check out nicehash.com profit calculator and use their hashrate for Equihash, Lbry, and LyraRev2 algorithms on the whattomine.com calculator you will see that their are several coins that do very well with NVIDIA right now. ZEC, VTC, MONA, and Lbry are coins that come to mind atm, there may be others that I can't think of off the top of my head.

VOTES for v 12.5

Yay! We need more speed! 

More speed is more difficult.

Who cares about speed at this point? Give me more solid code, and lower dev-fee
