Title: Problems with all catalyst drivers and win 7
Post by: Ntrain2k on February 24, 2014, 10:57:55 PM
Just reaching out and hoping someone might have ran into this and solved it.

Have a windows 7 box with a 6970 in the PCI-E x16 slot. Have a 6950 flashed to a 6970 in the PCI-2 z1 slot on a powered riser.

Can clean the drivers and install any version of catalyst. On 1st reboot after driver install rig mines fine.

Any reboot after 6950 card hashes next to nothing. Have to clean drivers and reinstall for it to come back and then it is the same thing again.

Anyone have a solution?

Thanks in advance for any suggestions/recommendations!

Instead of flashing a 6950 to 6970, use the original 6950 BIOS and use RBE to unlock the shaders.

This allows you to increase hashrate but at the lower voltage that the 6950 can withstand. Otherwise funny things can happen like overheating, throttling and killing the card soon. Also, perhaps your riser isn't that good.

After flashing the unlocked 1.1V BIOS, put the 6950 on the PCI-e 16x slot and see if it hashes fine.

That is what was done. Card hashes fine, no overheats or anything. It was in the X16 slot by itself before I got the 6970 and hashed with no problems.

Pretty sure this is a driver issue.

Which version of drivers are you trying?  Would have been useful information in the first post.

I have tried almost every version there is.

Currently trying to use 13.1.

I suspect it is UPLS, (buggy) power savings mode.

Either http://forums.guru3d.com/showthread.php?t=342695

Or use the Sapphire Trixx utility to disable.

I'll give that a shot when I get home.

Thanks!

Nope, looks like that wasn't it. ULPS was already disabled.

Redid them anyway and it still does the same thing.

Anyone else?

No, it looks like that WAS it!

You can't go by just those directions though. Apparently ULPS is in several places. I did a search for ULPS and there were probably 40 of them in my registry. 2 of them were still set to 1. Wiped drivers and reinstalled and then did the registry edits before rebooting.

You are the man!
