Sry for noob question but can someone tell me how to backup eth wallet
yes i wonder about this too, all i do was copying the wallet.key to flash disk and print it on paper. i wonder if there is easier and safer way Where can I find wallet.key? There is no "wallet.key" file. Sry for been so unfamiliar with eth wallet

There is no "wallet.key" file. Sry for been so unfamiliar with eth wallet in linux, its in ".ethereum/keystore/" folder, i guess in windows you can search for the folder name which is keystore, then copy the whole folder.

Hey guys. About 2 hours ago now I started getting this error: Allocating/mapping single buffer failed with: clCreateBuffer(-61). GPU can't allocate the DAG in a single chunk. Bailing. clEnqueueWriteBuffer(-38) I am mining on an r9 270 2GB using cpp-ethereum v1.2.2 for Windows on Windows 7 64-bit. I did some digging and apparently it has something to do with the DAG being one single chunk that is too large for the GPUs memory. I also have an r9 290 with 4GB memory in my system and mining still works fine on that. When i type "ethminer --list-devices" I get the following output: Listing OpenCL devices. FORMAT: [deviceID] deviceName [0] Hawaii CL_DEVICE_TYPE: GPU CL_DEVICE_GLOBAL_MEM_SIZE: 4294967296 CL_DEVICE_MAX_MEM_ALLOC_SIZE: 3019087173 CL_DEVICE_MAX_WORK_GROUP_SIZE: 256 [1] Pitcairn CL_DEVICE_TYPE: GPU CL_DEVICE_GLOBAL_MEM_SIZE: 2147483648 CL_DEVICE_MAX_MEM_ALLOC_SIZE: 1408867653 CL_DEVICE_MAX_WORK_GROUP_SIZE: 256 I can see that the DAG file is now 1417674752 bytes so it would seem the DAG has just grown beyond the allocated memory. I have tried deleting and building a new DAG, uninstalling my drivers with display driver uninstaller and re-installing the crimson 15.12 drivers. Also I have tried setting all the following evironment variables, and rebooting, and setting them again: GPU_FORCE_64BIT_PTR 0 GPU_MAX_HEAP_SIZE 100 GPU_USE_SYNC_OBJECTS 1 GPU_MAX_ALLOC_PERCENT 100 GPU_SINGLE_ALLOC_PERCENT 100 as was suggested in this thread on github but it had no effect. I suppose I can try the 16.x drivers (in fact I will do that next) but I used those before and they dropped my hash rate by 25 or 30%. Is anyone else having this issue on 2GB AMD cards all of a sudden. Any foolproof way of allocating more mem? Any help would be appreciated. Thanks.

Okay not sure exactly what I did but I was playing around with the "setx" command and rebooted and now I have the following reg keys in HKEY_USERS\S-1-5-21-xxxx...\Environment: CL_DEVICE_MAX_MEM_ALLOC_SIZE 1800000000 GPU_MAX_MEM_ALLOC_SIZE 1800000000 Along with the other setx parameters I listed earlier.

Maybe someone has more insight on a more elegant solution?

Rootstock enters the autumn of 2016 also ethereum touches are painfully.In contrast, RSK Labs plans a launch of Rootstock in a private test network in late April and a public beta release in September. The ultimate goal is a 1.0 version of the block chain end of the year. The previously mentioned Funding will be used to realize these timelines.

I have 2 ring with some error:

It has been asked probably numerous times, but what's the easiest way to check my computer's time and where to check it. Also how do I sync the time in the easiest way? My client has been stuck and it's not updating.

If you are using Windows, select the clock, change time date and settings, Internet time, Change settings, (select server) update now.
