[oobooee]

Hi, i'm not able to mine with the new version 2.14.0/1 on win10 64bit.
No prob with the previous versions.
I'm not so skilled, so, what i've to do to try solving my problem ?
Tks.
That's the output i get from:
xmrig-amd.exe -o stratum+tcp://pool.supportxmr.com:5555 -u XXXXXX

Older than the islands chips (GCN1 or worse) requires similarly ancient driver like 15.x Omega
There is a version for Win7 that still installs on Win10

It is the only driver that compute properly with the "Evergreen" series (Cypress, Redwood, etc) - every other driver newer than that has broken OpenCL on old cards (older than Tahiti/Tonga/Hawaii chips or so), it doesn't do memory allocations correctly, and was never and will never be fixed. That has such small memory that it should run one thread, but your max alloc is 0.31GB (320MB) which is the sign of the bug, and with the old working driver that would show 1GB/1GB/1GB thus allowing a single thread. It split into two threads due to this memory allocation bug in drivers newer than Omega. Even when it does allocate, it doesn't work (as you've seen). It should show hashrate if you act like it has 320MB total VRAM (like single thread, at silly low intensity+worksize, will get a silly low hashrate like 10, but it does hash). Nothing but the ancient driver does the old-card memory correctly, thus won't hash at correct rates.

Also those Evergreen series cards can never do CN-R as they are missing a required float-rounding mode that newer GCN's have (based on a Redwood HD5770 I used to run).

Same applies to Linux drivers, although 15.x doesn't work you need exactly fglrx 13.152 which means old kernel (3.2.0) which means old Ubuntu 14.04 (not even LTS or the kernel goes too new) and not the fglrx 15 that comes with Ubuntu either (find 13.152 debs somewhere and dpkg them)

Just mentioning that in case you thought it was only windows bug. It's global AMD bug.
