I'am new to zcash mining.

I've got 325 Mh/s / Sol/s with one R9 290 and less power consumption compared to ETH Mining. Good?

You can do much better. Hawaii seems to respond extremely well to tighter timings. Here are two threads to get you up to speed:

http://www.overclock.net/t/1561372/hawaii-bios-editing-290-290x-295x2-390-390x

http://www.overclock.net/t/1564219/modded-r9-390x-bios-for-r9-290-290x-updated-02-16-2016

You should be able to get 350-380 with a reasonable core clock / undervolt, more if you then decide to push the core.

Wow, I've flashed the ROM. Now I've got 362 H/s with less power consumption and (only) 947Mhz core clock.
The RAM got tighter timing, but changing the Memory Clock (for example from 1250 to 1100Mhz) doesn't change my hash rate.
Only clock rate influence it. Why?

What do you mean?

[Sir_IVo]

90sec Fee with SSL/TLS enabled ?! WHY ? in the readme.txt it sayes that the fee must be 2% - 75sec when SSL/TLS are enabled??? why the Claymore thakes 2.5% fee... ?

Any1 running rig with multiple GPUs on old lga775 boards?

Every time I plug riser into pcie x16 slot, the system won't start.
What could be the reason for that?
when pluged only pcie x1 works normal.
I tried changing video setting in bios (onboard, pcie...)

Has some x16 slot that works only with rise x16 to x16

or you need to short the pins with a wire

Why using x16 riser?

Why using x16 riser?

OLD 16X-16X RISERS ARE NOT SO GOOD--

But, apparently some old motherboards with old BIOS chips require them, or the use of a "presence short" that allows the detection of the GPU with a PCIe 1X-16X riser.  16X-16X risers can overheat, melt, and catch fire.  They are also stiff and inflexible.  The GPU will need to be directly above the slot and close to it.  I have at least one 16X-16X riser and could never use it because the GPU would not line up with the PCIe slot in the rig frame that I had.

They are obsolete.  Old instructions on rig building may use them, but a recent motherboard will be fine with good quality USB risers that do not require a presence short.       --scryptr

Is 12.5 the last planned version?

Probably not... I believe Claymore has said that he was going to get Vega GPU's running on this, but mostly that he was going to focus on this at the end of this month/into next month, probably when RX Vega gets released en masse.

Very disappointed with claymore’s miners. For both the Ethereum miner and zcash miner, it only detects my 6GB HD7970 as a 3GB card, automatically reducing the intensity for the zcash miner.

No other miner or piece of softwarehas this issue. Is there any way to override the miner automatically reducing the intensity?

Hello guys
I want to know what is the best version of claymore's Zcash miner for 7990 graphics card?
Im using 7990 card and It keeps crashing no matter how many gpus I use.
I tried different catalyst version and It didnt help whatsoever.
I would be thankful if you help me

This site has some testing regarding this model take a look

Was looking at the statistics on flypool where it shows the Avg. Network Hashrate is 223M while Avg. Pool Hashrate is 116M which makes up more than 51%.

So your disappointed with software that you didn't have to develop or pay for? Just checking. Not to be a dick, but if you wanted to you could go ahead and learn how to code and build your own miner. I get the frustration and the fact that your really just asking a question, but maybe read what you type first before you post. And I get that this guy is making a mint off of his devfee, I wish i could program better than him, but again just think before posting. I also get that this post isn't helping, but after reading sooooooo many similar posts, I barely have a tongue left to bite.

actually you are incorrect in the matters of that we don't pay for it, which we do pay for in the form of a dev fee. that said not much advancement can be made with amd and equihash, my question is why has he not reduced the dev fee considering amd gpus for the moment have hit there max, better yet why hasn't he removed the dev fee atleast with the zcash miner since he cannot make anymore optimizations in the code.  which quite franky makes sense to do

Yes, I am disapponted. You talk like if I’m saying I’m entitled to something, which I’m not doing. I like this miner, and I use it successfully with other cards.

With this card the miner doesn’t work so well due to a stupid restriction that assumes every 7970/280x has 3GB of ram, hence me being disappointed as I expected it to perform better.

Furthermore in a miner where you’re paying a non insignificant def fee, you have every right to expect that something basic like gpu recognition works on a basic level, or that at least there’s a way to bypass it, since it’s clearly made to help noobs, not that there’s something wrong with that, but you should be able to bypass it, since it obviously has flaws as seen here

Hey guys,
I have a problem which I'm troubleshooting for days, and still not solved.
I got R9 280X MSI 3GB, 12GB of RAM, i3 4160, ASUS H81M-E, PSU ThermalTake 400W

On this setup my last gpu 7870 2GB worked perfectly on NiceHash mining ZCash on Claymore's miner, when I set up 280X, there are problems income..
First problem was GPU #0 returned incorrect data! on Windows 10 WITHOUT OC, everything stock. I also tryed many drivers, 15.12, then lastest, everything the same..
Now I got another HDD and installed Windows 7 64bit(Basic theme, not aero), got NiceHash setted up, Claymore's ZCash miner, 15.12 driver for win7, and still the same. Then with lastest driver, same situation. Here I saw another problem, monitor goes off for 1 second and it says "Display driver stopped responding and has recovered".
Can anyone help me, what to do ? I tryed to underclock core and memory, It worked for about 6 hours without error and then it came again, I can't let it run for 24/7 without assistance. Also lower clocks get me about -20.000 sols than stock.
Can anyone at least give me recommendation for batch file for my GPU in this case ?

try v12.2b. If your card works with that version, might can be some r9 x80X related problem, because I have also "Display driver stopped responding and has recovered" popups with newer versions.

Thank you but I think I found a solution. I was googling a lot since that problem started and I found this https://steemit.com/mining/@felixxx/gpu-mining-equihash-undervolt-is-where-it-s-at
If you have same problem and same GPU, try this. My GPU is mining 1 hour without error or rejection on that settings, seems very stable.
I'll leave it mining for more to see if it's stable. All I need is stable rig because I won't be home to assist, restart or something.
Edit : Worked very stable for 2 hours and after that a crash.

My 6GB hd 7970/280x, even with claymore only detecting and using 3GB is getting 321H/s. It’s undervolted to 1.12v as it is a very high end Sapphire Toxic card which originally was at 1.26v and underclocked to 1140mhz from its original 1200mhz, memory overclocked to 2010mhz.

I had the same problem as you and tried to mess with the clocks and voltage but that wasn’t the issue. For me it was the temperatures. The card is fine as long as it doesn’t get pas 72C. As it starts getting close to 75C the display driver starts to crash and eventually the PC reboots.

I increased the fan to always be at 60% and that way the temperatures never go over 66 or so. It solved the issue for me, mining for 50 hours without issue

PS: And yes, AMD Wattman is a pain, it always tries to restore your old settings, everytime I change something I have to uninstall drivers with DDU and reinstall them
