Problem with GPU

[g3rr01]

I'm only mining at 15mh on eth on my gpu that normally mines at 30. I put it in another pc and this has happened. I believe all that is wrong with it is that I can't go into compute mode on it. I click on compute, hit apply, the app restarts and nothing has changed. What do i do?
is half performance normal on compute mode also?

you can try to enable compute mode in registry

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000


add dword32 -> "KMD_EnableInternalLargePage"=00000002

does this work for all gpu's?

If you are using Claymore miner, you can switch to compute mode with miner.
In readme file it says:
-y   enables Compute Mode and disables CrossFire for AMD cards. "-y 1" works as pressing "y" key when miner starts. This option works in Windows only.

You can find out easily. If it doesn't then do it for each GPU which can't go into Compute mode by removing all other GPU-s. Another simple way is to use the Blockchain driver as long as you don't have more than 8 GPU-s. I don't see any big improvement from the Adrenaline edition.

The Blockchain driver has the compute mode already activated. You just set the memory clock to 2000/2100 through MSI Afterburner and you are good to go.

The easiest way is by applying this tool:

More informations my friend. What card are you using? what miner? BIOS was modded or not?

You need to tell us what was happend between this happend 30>15 mh/s it was suddenly?
What is the Graphic Card
Some drops in mh/s happend if you change something in graphic card bios or you change something in overclocking maybe not good amount of energy
