Claymore's Dualminer: OpenCL error - 4 - cannot create DAG on GPU

Hello,

This regards the following error:

"OpenCL error - 4 - cannot create DAG on GPU"

https://drive.google.com/open?id=0B6HNx74FwQi2VXJDZjBQbjQ0QWs

4 cards mine and one doesn't. If I change the cards or PCI slots, the problem will move from GPU to another. Where before it was GPU1, then it became GPU 4. I am running windows 8.1 from a 64usb drive. When formatting the USB drive I formatted it the maximum amount of virtual memory, which was 59gb or so.

I can't imagine what is giving this issue. After 10 minutes or less this dual miner requested to shut down because it was out of memory also.
Any ideas for solutions please? I've noticed I'm not the only one who has had this issue but I could not find a resolution for them.

This is the .bat file I am running:
setx GPU_SINGLE_ALLOC_PERCENT 100
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_HEAP_SIZE 100
setx GPU_FORCE_64BIT_PTR 0
EthDcrMiner64.exe -epool us2.ethermine.org:4444 -ewal address -epsw x -eworker Worker01 -ethi 8 -mode 1

I tested if it is this is hardware related also. Disconnected a random card.
Then 4 cards mined without errors. Reconnected that card, and now disconnected another card.
This second lot of 4 cards also mined without any errors, hence eliminating the idea that this may be a hardware issue.


Cheers
