LTC mining problem: 7950 GPU OFF

[Africa2003]

Guys
I have Vapor-X HD7950 in PC with 1Gb of RAM (ordered new M/B with 16 Gb but its on the way)
Trying to run cgminer with different settings (taken from the similar 7950 setups on Win7 64 bit) but no luck.
It gives an error -4: Enqueueing kernel onto command queue
Is that because of the PC memory lack? What is the minimum requirement for such setup?

Thanks!

I would have to say it's lack of RAM, but out of curiosity, have you ran

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

from the command prompt?


EDIT: Also, what version of cgminer are you using?

Thanks for response!
I tried both 3.1.1 and 3.0.1
And yes, I've done these setx commands..
Hope my order with new RAM will arrive soon
