I added "-allpools 1" to the mix and did a test using the following configuration and it looks like it worked. I let it run for as long as it took to verify that it connected to the pool and started to submit shares so it may need some more tweaking to get it to work efficiently.
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_SINGLE_ALLOC_PERCENT 100
setx GPU_MAX_ALLOC_PERCENT 100

why are you using PTR 0 setting?
first post says to use PTR 1.
I thought PTR 0 is only for ethereum, NOT cryptonote.
Ooops ! My bad. I just copied the setx part from my ethash version of Claymore and pasted it in, but it still worked. I really don't really know what the setx bits do, so if it works and hashes OK then I just let it be.
EDIT: Just had a look here
https://cryptoyeti.com/how-to-make-and-work-with-a-windows-batch-file/2/ and it looks like either 0 or 1 will do.

GPU_FORCE_64BIT_PTR [0 | 1] When set to 0 allows access to 32-bit address space of memory ~3.8 GB. When set to 1 allows access to 64-bit address space. While it may sound like a good idea to set it at 1, it may actually hurt performance since then pointer access would require twice the number clock cycles to complete than it would if left in 32bit mode
