Known problems with CGMiner and Intel Z77 chipsets?

[timk225]

I had a problem.  I was using BitMinter to mine on a Gigabyte GA-Z77X-D3H motherboard, with an 850 watt single rail Thermaltake PSU and 2 6950's and a 6870, and it was solid.  But no way no how would this 'MA work on CGMiner!  CGMiner would almost start, then I'd get a message that Windows shut it down and Windows would notify me of a solution, which of course it never did.

I was happy to use BitMinter to mine BitCoins, but I moved to LiteCoin and DigitalCoin which are both scrypt coins.  This motherboard would NOT allow CGMiner to work, or GUIminer.  I had 2 other people in to help me with it, and they tried many different Radeon driver and SDK versions.  One suggested it could be a hardware problem, so I swapped in an Asus P8P67 revision B3 motherboard, with the same ram, same cpu, same hard drive, same power supply, and Windows 7 installation, same video cards, etc, and it worked fine, CGMiner started right up and worked.

I currently have it humming away on LiteCoin with 3 6950's, and I haven't had to touch or restart it in a week.

I did have to reinstall the Windows 7 and drivers for this motherboard, of course, but nothing different than what the other motherboard had.

So I wonder if it is a chipset problem (BIOS was F16 version on the Gigabyte board) or just this particular motherboard?

This motherboard was an RMA from one I bought on eBay that had its own problems.

You're using the wrong drivers.  I find 12.8 are the best/most likely to work.

I am using 12.8 drivers, and several other versions from 12.1 to 13.4 and the 13.6 beta were also tried.  Nothing worked.

You need to completely remove any and all AMD drivers, then reinstall the 12.8 drivers.  If you need to reinstall Windows, then do it.  Or run one of the many driver cleaner programs.

This problem is ALWAYS the wrong driver version - cgminer craps out because the SDK is wrong, so it can't build the kernel.

I run a Gigabyte GA-Z77X-UD5H mobo with cgminer and a 6870 with no problems. been running 24/7 since last december. its my daily driver PC.

I do have the latest drivers/BIOS from gigabyte on it.

This.

AMD has it's own driver cleanup tool too, wich works like a charm.
When there's junk left from older drivers, they interfere with the newer ones and will cause BSOD's.

After uninstall, reboot and install new drivers.
