So suddenly im getting windows defender saying "ethdcrminer.exe has been blocked from accessing graphics hardware" ive added the folder and the individual .exe to the windows defender exclusion list but its still happening. Can someone help please?

If youve got new powered risers then you must power them. I tried using new risers without power and they didnt work.

You will be very lucky if you get that rock solid at that mem clock. But it has been known to happen on here.

Simply dont use any GPU to mine bitcoins. Bitcoin mining is done with ASICs and has been for a while now. The most recent and efficient at the moment is the Antminer S9 or T9. You can mine other coins with GPUs and if youtake the time to search the forum (search is at the top of the page) then you will find all the answers you need.

Thanks toptek but not sure if the first bit of info relates as its to do with the dag file which i have enough in my system to deal with.

The forum link i only see one bit simikar but dont know what the guy is on aboiut.

I keep getting " gpuminer cu_k1 failed 4" when running my two asus cards (micron) and it restarts.

So ive started to use risers in anticipation of my order of two more Asus 1060 O6G cards getting back into stock and now ive run into more problems than i previoisly had. The setup is as follow:-

Asrock Z270 Pro4 Mobo
Corsair Vegeance DDR4 Ram (2x4Gb)
Intel i3 7300T
2x ASUS GTX1060-06G
1200w HP Server PSU running a 160w pico Psu.

4G decodin enabled and pcie settings are "auto".

Each riser has a 6pin connection direct to psu breakout board (sidehack/gekkoscience).
Each GPU has a 6pin connection direct to psu breakout board.

NO adaptors or Y cables have been used.

Basically i seem to be getting more of the error in Claymore that says "gpuminer cu_kd failed 4". Got it a few times when the two GPUS were direct to the mobo but mow on risers it seems to happen more and restarts. Has anyone had any experience with this?

P.S. when its working its obviously working as it should and getting the hashrate it should aswell.

So turns out it was the PSU afterall. Managed to jerry rig my pico and server PSU together and get my mini rig up and running again.

Thanks for the replies guys. But that wiuldnt expain why connecting the psu to an ATX breakout board only would produce the same results. Switch on, click, lack of power.

That is one card, EVERY card has the chance to get any of the three memory types.

It was what i had left over from a small btc rig of gekko sticks etc. It has worked fine until i switched it off and then reassembled the rig in its new orientation and tried to boot up. Ive got a pico psu and waiting on a custom cable to power it from a 6pin connector as ive got a 1200w hp server platinum psu with gekkoscience (sidehack) breakout board which will power everything.

Just need someone to confirm that it is the psu thats dead seeing as the old psu i found in a cupboard switched the mobo on.

Nothing was connected to the mobo. Just tried the 24pin breakout board with a multimeter attached and got a brief 12v which sooned dropped to 0.

Just found a really old (10plus years) psu and connected the 24pin and the mobo fired up. Didnt get anything out the screen but it hasnt got an 8pin connector. Hopefully i havent done any damage but still it stayed on for a few seconds until i switched it off.

So looks like the XFX XTS 520w fanless psu is dead. I did have a fan ontop of it and it was only running 170w while it was mining.

Its been running for days. Just unplugged everything to move it around so i can mount the gpus on risers and now it doesnt fire up.

Got a 24pin breakout board i just tried on its own and it wont switch on with that either. Does that mean the PSU is dead now?

So ive just got some risers and installing them, move my rig about and sort out cables and now it wont fire up.

The psu clicks on and the processor fan spins a couple of times and then it stops. Only thing i have plugged in is the mobi 24pin and the CPU 8pin. Nothing else is plugged in (no hdd or gpus. Riseds are even unplugged. Literally the 24pin and 8pin power is connected from the psu. Only other cables attached is the VGA to the screen.

Anyone have any ideas?

Its a lottery as they all use all three types even in the same model cards. Download GPUz and see what memory it has.

Firstly welcome to the forum. Secondly this needs to be in the "Mining (Altcoins)" section of the forum. Thirdly are you hsing any kind of plug adaptors, like molex -> 6pin etc?

I'd like to give it a go but it doesnt pick up my two 1060's only rhe intel onboard graphics (primary as the hdmi port is being used so using the vga on the mobo).

Well that explains it. Ive set it to onboard because ive got a vga port on my monitor and the hdmi is already being used. Oh well ill stick with claymores. Thanks for the info.

Found i downloaded the weong thing. Got the right thing and it starts but inly finds the processor onboard gpu.

Same bat file info as before.

Can someone point me in the direction of the correct place to download Genoils Ethminer for Win10. Downloded something from github and created a bat file but ut flashes up and then disappears. Used the info from the homepage of ethermine.org to create the bat file.
