Topic: DiabloMiner GPU Miner - page 33. (Read 866596 times)
Update: Added two models to bfi_int whitelist, fixed up loop code, added optimizations, fixed a few bugs
My statement is true for current SDK and driver versions and that's what I meant. Sorry if I was a bit unclear 
.
The whitelist is "nice to have", but it can be hard to maintain such a thing and keep it up to date ... I saw that "Loveland" for example is missing. That's the GPU part of the AMD C-50 and I'm 99% sure it works with BFI_INT patching.

The CPU core half of that Fusion may identify itself as Loveland, but the GPU half, the Radeon 6250, identifies itself as a Wrestler.
Edit: I don't see any of the APUs named Loveland either, there is only Desna, Ontario, Zacate, Llano. Trinity, Weatherford, and Richland aren't out yet, and will use Northern Islands-based shaders (77/78/79xx) instead of Evergreen (5xxx). There is also three that were canceled, Krishna, Wichita, and Hondo.
Although, it seems I need to add two more names, Palm and Sumo.
Diablominer doesn't work here on a freshly installed 7970. I have the newest driver that supports 7970: http://support.amd.com/us/kbarticles/Pages/RC11Driver.aspx
I installed the AMD APP SDK that came with that.
So the miner starts normally, albeit with some Java error (installed newest Java just in case), then waits for a while, and after that just shows 0 MHash with the card not doing anything. I think my install should be fine, as cgminer "worked", although it gave me like 130MH/s

Your command line is screwed up. Although, it shouldn't exception like that either. If you're using -o, you want -o api.bitcoin.cz
get rid of the "http://" at the beginning of your URL. You aren't connected to a pool.

By the way, AMD makes the use of amd_bitalign() obsolete for rotations, so it's safe to use rotate.
That is not an accurate statement. We have not had to use that since SDK 2.2, this was for 2.1 only. 2.2 or later on any hardware optimizes rotate correctly.

And it seems BFI_INT patching is not needed anymore for 7970 cards, did you observe that, too?

Yes, which is why I added that driver name whitelist. cgminer has also copied that whitelist as well.
For the first time in history, no arguments are the best. I have no clue how the hell that happened.
Ha!
With I get ~539 MHash/s ... this should be the preferred command line, right?
I'm currently testing other kernels for GCN performance

-D 1 -v 1 -w 256 -aa

-D is useless unless you're turning off other cards. -w 256 is default. -v 1 is default -aa does _absolutely nothing_ and I've already renamed it to something else in a local branch.

Well it seems the GCN architecture is pretty straightforward in terms of optimisations. You don't have to fiddle around that much with the ordering of commands and that stuff.

7970 tweaks? Kthx. 
Apparently it was a false reading. Not sure why this would cause a false mhash result, but apparently my CPU was previously set to be overclocked, not even sure how- I think it was some auto setting on a new BIOS I installed on the motherboard. Anyway, I reduced it to stock speeds with AMD Overdrive and apparently it screwed up something major with timings which led to the false mhash value and incidently broke a few other pieces of software (games). After rebooting and setting the CPU back to completely stock speeds in the BIOS this corrected the mhash value.
You should be able to get more, assuming you have the GPU at 950.
I'm now getting 396-399 mhash with Diablominer, which is still a nice 16-19 mhash improvement over what I was seeing in guiminer, but not crazy high anymore.
This is win7 64, 11.12 drivers, radeon 6970 (some manuf. reference design), 950mhz GPU, 1375mhz GPU RAM, 0% power increase, 65% fan to keep around 70-75C.

That is awesome, I'm glad I switched. I couldn't get more than 380 with guiminer, even at 950 core.
Could you share your setup, please? I'm unable to reproduce this miracle of yours
Only getting around 380 with Diablominer.try with no flags.... I have a couple of 6970's and will be trying this pronto!!
I tried this... can't replicate the results.... no flags latest diablominer... and I'm seeing 360m/hash - 370m/hash

Yeah, see, thats where I'm questioning this. I mean, -v 2? sure, -v 2 is fucking magic. -v 1? hell no, even 2.6's screwed up existence, where it sits at the back of my fridge begging for me to kill it, cannot do that.
CATS, DOGS, LIVING TOGETHER! OH THE HUGE MANATEE!

Only getting around 380 with Diablominer. Sorry, I'm blind. Yeah, we've been having a kernel arms war lately. What you're getting sounds in the right ballpark.

Note that it's not stock, I have the GPU clocked to 950 through CCC, but looking at the hwardware comparison page it looks like it should be around 430 mhash tops, so I don't think that fully explains it unless the hardware comparison page is just out of date.
