Catalyst 5.12/5.7.1
Windows 7/8/8.1/10

All of the above give 2MH until it's flashed back to the stock bios.

Hello,

I have been trying to undervolt my 3x Asus R9 7970 DC2Tops and 2x R9 280x DC2Tops for a while now but have not found a solution.

1. I Have flashed the above to 1050v, 1075v, 1100v, 1043v, 1056v, 1100v, and 1143v.
2. For all the above voltage variations, when I start mining, I get get 2MH.
3. I flash it back to stock bios and the card gets back to mining 21MH / works like new again.
4. After flashing with different voltages, kill-a-watt / GPUZ still show 1.2v or same wattage as before.

These cards seem to be locked as voltages don't change after flashing with ATIFlash outside Windows.
Any .rom file changes what so ever seem to dramatically reduces my hashrates as noted above.
I would gladly accept someone else's undervolted ROM file for these cards as I have run out of ideas.
I am very stuck. I would appreciate any ideas / input about what is happening with my cards Smiley


Many thanks

Thanks for the quick reply Claymore.

I think it may be something different.

Your readme file advises that for multi-gpu support 16gb is needed as virtual memory.
I think I saw this we the program ran also. I went to change the virtual memory in advanced settings.
However, the virtual memory never saved properly. I set the memory through command prompt also.
The memory allocation either never saved properly or windows came back with an error after rebooting.
It seems like Virtual memory cannot be set onto USB drives, which is how I have been running Windows.

I hope that this was the problem all along, which is easily fixed by going to the shop and picking up a bit of hardware.
Assuming this was the problem, then you still have awesome software, though 'probably' cannot be run on USB (power saving?).
I like this software because it just hashes better. Perhaps in future an option could be coded to create DAG files again.

Hello,

This regards the following error:

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


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 is a hardware issue.

Cheers

Claymore, do you have any advice on this please? I have 20 R9 280xs that would love to start mining with your program Smiley
