I have no problems with the .exe. Not sure what crosswire downloaded
Currently looking into it so far:
- It only triggers on windows 7, not on 8 or 10
- it reports changed LNK files on the quicklaunch of the logged in user
- it reports VulkanRK in the programs x86 folder
- it reports VulkanRK in the registry
after that its silent again. There are reports of that old version giving false positives on the last two items, but the first two are still weird.
MD5 matches on my side from what the developer e-mailed me:
MD5 4e84cd13c3f081b715cb66bba0981c9a
for me -u and -p are perfeectly working
Hi all,
I have honestly no idea what is going on on crosswireās systems. I compiled the miner on my private laptop and tested it on 2 different systems, but both are running Windows 8.1 and Avira as a virus scanner, no weird behaivior so farā¦
Still, until this issue is cleared up, I recommend not to download the windows version of the miner. I took the link offline for now.
Would be really weird if itās a virus to only effect W7 and not 8 or 10ā¦
Also running out of memory with a 32GB pagefile and 6x 1070s on W8. -t 16. Increasing my pagefile or decreasing threads helps, but this miner uses a LOT of virtual system memory (not sure why). It also pegs my CPUs with five GPUs running, sixth obviously reduces the overall miner speed.
Pagefile with default threads and 6x 1070s is at 40GB(!).
Can you do a build with VS2015 and Windows 10? Iām running it on Windows 10 AU x64.
Cuda 8 Framework install drivers 373.06ā¦
Sofar i get 350H out of 3xGTX1080 and 2xGTX1070. OC donāt seem to have any effect ā¦stay always at 350 around.
Could you also please format the output a bit with colors and proper spacing 
that would be awesome
Like claymore did you see when mining dev fee and normal mining. Accept and rejected sharesā¦
P.S Still issue with extranounce at some pools.
Maybe because this miner is actually doing CPU mining behind and not only GPU mining. It can be easily masked (with some sleeps) so that taskmgr shows near 0 or even 0%.
Not sure what youāre saying. You can shut off the CPU mining in NHEQminer. The CPU workload seems to increase linearly with the number of GPUs selected, so Iām pretty sure itās not CPU mining.
If you notice CPU workload increasing, then there is really something odd going on. Or perhaps this miner is doing job half CPU, half GPU.
Well the hash is going very high not possible with cpu only ā¦but it stresses CPU 50% with 5cards.
Since you didnāt released yours Iām not sure what choice we have to keep up with AMD Miner from Claymore.

It wouldnāt increase with the amount of GPUs selected linearly. That and memory usage. Iām guessing after it creates the files in system memory and transfers them to GPU memory, it never frees up system memory. Loading each GPU and then freeing system memory would elevate this. Iāve seen behavior like this with other GPU miners in the past.
The CPU utilization could be caused due to the shear amount of system memory itās accessing and never frees. Considering other miners use almost no CPU cycles this is weird and probably a bug or unoptimized code, much like with the memory allocation.
We could see if RAMMAP will fix thisā¦so we can clear of that part manually. I will give it a try.
checking it in another more then 100 VMās trying to reproduce the VirusScannerās report i so far was not able to reproduce
external firewall showing no strange activity and the files that are changed dont seem to have code thats should be reason for concern ā¦ sofar it all points to a false positive
Hi crosswire,
Thanks for the analysis. Iām glad there were no further issues. Still, the behaviour on Win7 seems a little weirdā¦
@Bensam123
The pagefile issue seems to be some CUDA thingā¦ it didnāt happen on the 2 systems I tested the miner on.
My code used cudaMalloc() to allocate memory, which should in theory allocate only on the GPU.
I think this has something to do with NVIDIAās Unified Memory and causes CUDA on some systems to allocate the used GPU memory on the host too.
@djeZo @Bensam123
The high CPU load comes from CUDA waiting for the kernels to finish.
CUDAās sync mode can be switched to a blocking sync, resulting in almost no CPU usageā¦ but this method was slower when mining on one card.
However, when using more cards, it might actually be better. I can post a another version with blocking sync and low cpu usage.
@ioglnx
I can do colors later once the main issues are resolved 
Looking forward to this 2nd version with blocking sync
With Nicehash buying up the new, faster, miner you might want to consider selling your changes and optimizations to Nicehash. This miner is only going to last up until they release theirs (if that with Claymore 100sol v4 bombing the network) which will probably be in 1-2 days if I had to guess randomly.

Windows binaries wouldāve been a lot nicer if you posted them back when you did the initial release. 
until thats actually here ā¦ i am not assuming its coming
Since itās been officially confirmed that itās on its way, then itās on its way.
Hello,
on my system the miner just allocates 15mb virtual memory. Nicehash is using far more when mining with cuda.
@zcminer-dev: Maybe build in a switch that let us decide the CUDA schedule mode like ethminer ā¦sync,blocked autoā¦
The colors are nice but also the latest builds have it disabled from nicehash because trupvot has disabled them
Hi,
here are the links again. Low CPU version might be better when using multiple GPUs.
Default version:
Low CPU version, might be better for multiple GPUs in one system:
@Bensam123
Yes windows binaries would have been a lot more useful a week ago. But it took me a while to get it working under windows. Compiling under Linux is much more straightforward imo. Still, I have some room for optimization so I could probably get to 80-90 Sol/s if I do some profiling.
@ioglnx
Nice idea with the switch. Next version will allow to choose sync mode

Tested and CPU usuage is low on my E5 1650v3 just 7-12% and hash is as high as with high usage.
Good work. Looks pretty much what doc ordered.
The nsight gpu monitoring also shows a bit better latency overall for all gpusā¦great.
Side effect the the Windows desktop is much smoother and other app you need to use.
Little update from 10min usingā¦peaking about 450H/s ā¦lovely.
