[Dowper]

after reinstalling OS win7 my miner sees only 4 of 6 gpus.
Why?
Can anybody help me?

Did you use the 6 gpu mod?

try win10

I had win10 before - hangs
now i'd like to use win 7_64 - problems - only 4 cards (i have 6). After updating drivers - no cards.
miner does not start at all:
There is no openGL...

You should change your risers first of all. I had bad luck with shitty risers months ago. Sometimes the card appear sometimes not. I thought the problems were elsewere but after changing two (!) packs of risers finally the problems dissapeared for good. The next thing is to use windows 8.1 64 bit, especialli if you have h81 mobo. They are really well optimised for this OS. Moreover, windows 10 will have bigger load on the cpu which can slow your cards when mining. In my case win 10 is above 90% whereas win 8.1 around 20%.

You should see 6 cards after the drivers install and 1 probably with an exclamation mark in the device manager. You need to run the 6 card mod to be able to mine with all 6.

You dont need to buy new risers. Look at thi solution, it works for me.

1. I see see 6 cards after the drivers install and 1 with an exclamation mark in the device manager.
2. what is "the 6 card mod"?

[carlo_0000]

just google it s a patch for allowing 6 gpu under win7

Always take a reg backup, force if needed.
You can either create modded registry and double-click on it to inject or just tick modify-registry.
Works for me with 16.10.3 drivers

does not help me - system needs driver for OpenGL 2.0....
probably I need to move to win10

[LithStud]

So i am having somewhat strange problem, after a while H/s drops from ~140 to ~60 (using R9 270x 2GB on Win10). Tried another miner and it got me expected, for that miner, ~130H/s

I am sure after i restart my pc it would go back to ~140, but thats of no use if later it again will drop.

win10 - miner works (all 6 cards)
but speed 710, before I had 770 on one card (xmr)

I've been mining for nearly a year. Of course I know about this page. Obviously you didn't have risers that work with their own will like mine did. Again: bad riser can cause the OS not to see the card in the Device manager, or you can see it randomly on restarts, or can work really poorly crashing the drivers at the end. This can't be checked with this page or any other methods except changing the risers. Believe me, I had 5-6 faulty risers (powered usb) ordered by ebay. Finally I ordered more expensive but really good risers from amazon and they do their job perfectly.

PIC cables have nothing to do wit hit

its about drivers and overclocking

Hello friends! Want to play with diff option in miner to set my own diff. What is the best values for 4 280xs ( 860 h/s) and 3 rx 470s ( 660 h/s) ?

Thanks for any advice.

HI all)
what's the most profitable Crimson for only RX4xx?

 In my testing, 16.10.1 and 16.9.2 proved to be equal.

 I suspect any version from around 16.9.1 up to the last pre-Relive version (16.11.whatever) probably gives the same hashrate results.

 16.12.1 gives 5-10% LESS hashrate in my testing, and should be avoided.

Thanks. So I will stick with 16.9.2

When I start the miner it says 14 compute units for each graphics card.
I have RX 470s so should that not be 32 compute units?
