For reference, my AMD 290x's top out at 373 H/s per gpu. 12.3, asm 1, intensity needs to be around 6. Anything else and it diminishes significantly.

The bootstrap.dat file is only needed if you are re-syncing. It will help speed up the block import process. If your wallet is already in sync and showing the green tick then you will not need it.
Next step is check your wallet is showing the same block height as the block explorer (currently 643277)

Now restart your wallet using the -rescan switch to see if it can recover missing transactions in your wallet. e.g.

Windows:
1) Using the command window, navigate to the folder where the executable is located
2) Run the following command...

Mac:
1) Using Terminal, navigate to the folder where the boostcoin app is located
2) Now navigate to this folder inside the .app where the boostcoin-core-qt-v4.4.1.2 binary is located
3) Run the binary using this command with the -rescan switch

--cl-global-work 16384 (4096 or 8192 for CUDA mode)
--cl-local-work 64, 128 or 256 depending on card (128 for CUDA mode)
--farm-recheck 200 according to most pools.

--cl-global-work is another way of expressing intensity. lower it to 8192, 4096, 2048, 1024 and so on to lower GPU usage. hashrate will also go down at some point.

Investigating some back end issues now, will have this fixed soon.

Try these?


thank you !

Try to add this to .bat file:

setx GPU_FORCE_64BIT_PTR 0
