Topic: Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux) - page 1114. (Read 6590565 times)

Didn't check log file but pretty sure that it was the intel igpu that was causing your program to not read the temps from my amd card because after disabling the onboard video and plugging the display directly into the amd card it started reading the amd cards temps after a reboot.  Is there anyway  to force the AMD api to read temps when it is using the Intel opencl platform?

Bios throws error telling you to plug in the 4-pin molex power on the motherboard.

ZCash will use Equihash as an hashing algorithm, which is an asymmetric memory-hard PoW algorithm based on the generalized birthday problem. It relies on high RAM requirements to bottleneck the generation of proofs and making ASIC development unfeasible, much like Ethereum.

I have two rigs running 6 Sapphire 480 Nitro each with that mobo.

Using powered usb risers, no need to used the mobo molex connectors

Win10 x64 + AMD drivers 16.9.1

Very stable, no problems whatsoever 

Zcash will be scrypt-n from what i read.

I will check this coin when it is released, right now I'm busy with other things.

Hey Claymore, will you support Zcash mining with your software? lots of miners are expecting that coin release.

Solo mode is supported. Read OP or Readme for sample command line.

Thank you, i build my own getwork pool but.. i am trying to mine with claymore on it is posible?

"-etha 2" will help you. Within 24 hours I will release an update, this option will be set automatically on Linux+gpupro.

on ubuntu i get this syslog 50GB

Powered risers would help but definately connect mobo molex connector to the psu to give juice to the pcie slots.  If using windows all should be good.  I had problems with Linux on that mobo.

What I have tried so far is:

- lowering pci to GEN1 in BIOS
- remove any possible interfering software
- visrtual mem. to 16 gb

So far we have been able to make 5 GPUs run at the same time, now we are trying to understand if the last one has a riser problem, or something else.

Which mobo do you suggest for an eventual next rig?

Also which field of the BIOS should I edit with "8/4/4 for the x16 slot"?

Thanks

Plug your Display into a other GPU
If i start my Miner i had a black screen on the last GPU, so i move my Display to a other Card an tut works

Best Regards

Hi there claymore suports getwork?

Quite some people are talking about lowering pci-e gen in BIOS from 3 to 2 or even 1 in order to get more than 3/4 GPUs running. Maybe that's the issue? (Note: I don't use the BTC Pro boards and I don't have that kind of issue with any of my (countless) rigs, so it could be something completely different...)

Good luck!

Edit: ...and 8/4/4 for the x16 slot if this is possible in this board's BIOS...

You mean to try the slots one by one? So it could be a mobo problem?

I have a few of these boards setup and they can be quite fussy, try adding the 4th GPU into each spare slot in turn.

For example, 1 of the H81s will not work at all, if the x16 slot is used so that rig only gets 5 cards :/

I don't know why lots of people think you need to power the molex on mobo.  If using the 1x-16x powered USB risers, they are completely unnecessary.  The risers are all powered, there is 0.00000w going through the slots on the motherboard.  The molex on mobo are for if you are using non powered risers.  I have that board, and it will run fine with 6 cards, nothing plugged into mobo.

Thank you, I will try it now and see how it goes!
