On windows, you can also specify "export GPU_USE_SYNC_OBJECTS = 1"
Only way is different, "Computer> System Properties> Advanced system settings> system environment> create a new variable" GPU_USE_SYNC_OBJECTS ", the value of the variable is -" 1 "

Thanks!
This fixed my high cpu usage on Catalyst 12.2.

Just tried this....  does not work on my win7 64 rig with 5x7970.  tried in the bat file and in the environment vars...

It just has no effect at all on Windows systems (confirmed by AMD). You could as well set MITT_ROMNEY_IS_A_DICKHEAD = 1 ... would have the same effect

You jerk.  I set the MITT_ROMNEY_IS_A_DICKHEAD = 1 flag and within minutes I had some Jehovah's witnesses at my door trying to convert me.  I am never going to do that again.

you sure they weren't Mormons?

ahahahaha, I could understand that happening if you set the flag to 0, but when set to 1 you get prohibitionist Mormons armed with choir recordings.

Just installed 11.6 on 64-bit windows 7, and cgminer 2.2.3 was only showing 1 GPU. I updated to cgminer 2.2.6, and now I get this:

Code:

Too many values passed to set temp cutoff

Do I need dummy plugs for the cards, or is there some other issue? Should I just suck it up and install the latest drivers?

Further to this, when I do "cgminer.exe -n", I get:

Code:

No monitors or dummy plugs are connected. I also tried the SDK 2.4 standalone installer, and get the same results.

11.6 needs dummy plugs on windows. You need a later driver but beware of SDK fuckage.

Damn, I thought that was the version that removed that necessity. I'll try something newer I guess.

[DeathAndTaxes]

Any particular reason you want an ancient driver?

You can install driver & SDK independently.

So you can install driver 11.12 to get the no CPU bug and then SDK 2.1 to maximize performance of 5000 series cards.  Be sure to delete any existing bins and run cgminer to compile bins with SDK 2.1.

Well I wondered that, but I thought that newer drivers refused to support older SDKs. I guess I'll try it again soon.

I don't think so but with so many combinations of hardware, OS, drivers, and SDK YMMV.

Know how to do this on Linux ?

Or shall I just stick with 11.6 and 2.1 ?

Have you tested the difference between 2.4 and 2.1 on your 5970s ? Is it really that much better compared with 2.4/2.5 ?

I have 5870s only.

Thanks !

On Linux: when you install 2.6 you should do it manually.
It copies 2 libraries over the OS installed ones if you do it with the ATI install script.

Everything else is the similar to the cgminer README
(so is easy as long as you understand how to extract tgz files ...)

The 2 OS libraries are: libaticalcl.so  libaticalrt.so
So you need to save the old links (e.g. rename them: mv libaticalcl.so libaticalcl.so.old )
If you don't want to try mess with removing and reinstalling the fglrx packages later to go back to an earlier 2.x

Hmm maybe I'll write up the steps to go forward AND back later ...

Thanks for the heads up, that isn't the only danger with relying on the crappy installation script.
ATI always sucked where any coding was involved and AMD just kept ATI staff...

Well, I got it working, but my 5870s at 950/160 are producing 370mhash now.
That is suspiciously similar to stock, wonder if OC settings aren't being applied by cgminer? brb checking

EDIT: When I hit G then C then 0 and enter then E and typed 950 and hit enter and then Y, cgminer told me that the driver accepted the voltages, but that I should "check the values below". It didn't seem to actually OC the cards.

Right, that's why cgminer reports back the *actual* values because the driver can happily accept some changes and the card can happily ignore them.

But it was working perfectly on a previous version of cgminer... or maybe it was the driver changes to 11.12 and sdk 2.1 that caused this..? brb, downloading old cgminer version to find out.

EDIT: Damn, 2.2.3 (which was working fine before) is doing the same thing. wtf

Update on 7970 performance.

I did a little calculation to see how my 7970 is performing with the latest cgminer.

Clock per clock it is precisely 1/3 faster than the 6970 running at the equivalent clock speed.
What's hilarious about this is that the number of stream processors is precisely 1/3 more than the 6970 (2048 vs 1536). This is despite the 6970 running on phatk on sdk 2.5 and 7970 running on my customised poclbm on sdk 2.6. As I said before, at least on the 6970 which I don't grossly underclock the memory (only -125) I'm getting slightly better performance on poclbm with 2.6 now than phatk with 2.5.

So in terms of raw performance, I think the current cgminer release and kernel is doing pretty good.  

Alas none of the magic GCN changes that aren't just more processors appear to have been exploited, and every thread I've read on suggestions to exploit them on these forums has only led to worse performance, often disastrously worse.

Never blame the new version of cgminer. ALWAYS blame something else first.

I know right? But how would the change to 11.12/2.1 cause this odd issue, which I have never had before? Any ideas on debugging this? It is acting like no changes are being made at all - voltage, core clock, memory clock, etc.
