Hi, i received one RX 480 nitro plus 8GB and installed new drivers (crimson 16.9.1).

did you tried to used that card with another miner ? or a different version of claymores miner ? (6.0 ? 6.3? ? 6.4? 7.0? )
I have 2 of those card in one of my setup , and for some reason i always got in some trouble with that rig. sometimes one of that card hashing with 4mh/s , but working fine with another miner ... sometimes i got a gpu4 error ...

did you checked the card with gpuZ ? if yes , gpuz see the correct memory size ?
If noting see that 8gb ,  probably you need to RMA the card

i tryed to reinstall windows 7 64bits, flashed original bios in gpu and claymore works good.

But in the moment i put moded rom with polaris editor (only changed mem frequency, core clock and mv) and another time the same problem, all with 16.9.1 latest driver. the claymore detect with 3GB and don't work another time.

In polaris i dont changed nothing important i backup original bios, opened and changed setting with conservative setting for test first if works and modify bios more times for see what is the max settings with stability.

do you have at least 4gb or more of system memory installed on the motherboard ?
The low memory can create a problem like that , its going to happen with 2gb for sure , if you have 4gb it may will be ok may not , get  8GB  ,that should be enough .
8GB system memory should fix your problem !

I go to try to put more ram to pc i have 2GB, i tell something when test it.

Edit:

Yes! it's for ram i need more ram i put 2GB and worked, with win 10 or 7 64b need 4GB for this RX 480 nitro 8gb.

With 7970, 290x, 5850, 6950... i don't need 4GB but with this new cards yes.

Tnx a lot for your help, this make me crazy and now fixed the problem!!!
