Title: GPU Crashing when miner starts Post by: jswift1234 on December 04, 2013, 03:45:12 AM My GPU crashes in spectacular fashion as soon as my coin miner starts. By 'crashes' I mean the desktop PC loses power completely. Not a blue screen, just powers down. Pretty sure it's the GPU because I can get the miner to run with the CPU. Any ideas on what's going on?
Here's my configuration: VIDEO: AMD Radeon HD 6950 2GB GDDR5 16X PCIe CPU: AMD Phenom™II X6 1090T Six-Core MEMORY: 8GB (2GBx4) DDR3/1600MHz MOTHERBOARD: GigaByte GA-870A-UD3 AMD 870 OS: Windows 7 Home Premium (64bit) POWERSUPPLY: 800W XtremeGear I get the same error with GUIMiner, Multiminer, bfgminer and the BitMinter java client. Advice greatly appreciated. Title: Re: GPU Crashing when miner starts Post by: iiWii on December 04, 2013, 05:37:58 PM Try turning on vsync, was it working before? Or is this your first time mining

If it runs through, then try to clean up and reinstall your GPU drivers and OpenCL stuff. If it doesn't... well if you have no spare parts then I guess I'd try putting the card in another PCIe slot. Other than that I'd be pretty lost as it could be the PSU, GPU or motherboard.

It works till you try to hit the TDP of the card, voltage sags and it goes unstable and crashes.

Furmark may not be a good test if your computer crashes when scrypt mining as furmark doesn't actually stress the memory that much. If you're SHA mining then furmark would probably work.

I mean to say that a 800W "XtremeGear" power supply is nowhere near 800W, or probably even half that. If you knew how to read you would have picked that out of my earlier post. Don't have to believe me though, just google "XtremeGear."

Don't have to believe me though, just google "XtremeGear." No I agree with that. I was just getting clarification. Sounds like a shit no name brand. EDIT: And that is why I said "If you mean to say". Speculatively asking. Not asserting that is what you meant. No need to be rude. |
