Does EWBF need a large virtual memory swap like Claymore does or can I reduce the Virtual Memory size to reclaim some badly needed disk space?
My understanding is that claymore's large virtual memory requirement is associated with DAG, so no,you don't need a large swap file for EWBF as there is no DAG. I might be wrong though.
For more then 3 GPU - large virtual memory is required - 16 000 MB minimum.
I hope you know what you are talking about. Care to explain why?
I read that somewhere - If you are using multiple GPUs, recomended settings for stability is 16 000 MB or more.
Also when I try to connect to my PC more then 3 GPUs, miner was unstable all the time (OS Windows aswell).
Yes, you have to use at least 16 000 000 MB. If windows goes unstable, you might have overclock your cards too much. And yes, go and disable the windows updates.. .This thing f*cked up all my rigs yesterday...
Just because you both repeat something you've heard or read somewhere without understanding of what that means - it doesn't make it true. Without referencing the source (so that we can evaluate the info ourselves) you are just spreading rumours.
I like this explanation https://github.com/nicehash/NiceHashMinerLegacy/issues/6, that suggests that swap file for Claymore is taken by mirroring DAG from GPU to virtual memory. There is no DAG on GPU for equihash, and therefore my understanding is that virtual memory is not needed for EWBF. I'm not a big expert and may be absolutely wrong. Happy to hear from a specialist; not that this issue bothers me much, but since the question was raised - let's find the answer.
Me and my friend (from same town) just had same experience. Unstable windows during mining Zcash with EWBF. After virtual memory was rise to 16 000 MB or more - no more problems with stability. End of story for me.
