DiabloMiner GPU Miner

But you shouldn't be using -v 4 -w 64. That is not appropriate for the new kernel on vliw5. For me, -v 2 -w 256 is fastest, -v 2,1 -w 256 is slower, -v 2 -w 128 isn't faster (but -w is very sensitive to memory timings, so -w 128 being faster for others does not surprise me).

What kernel do you mean by "the new kernel"? I'm using the zip-package linked in the first post of this thread and this is still the "old kernel", isn't it?! I did not compile DiabloMiner from source so I guess I'm still using your "not optimized for SDK 2.6"-version. Maybe we can clear that confusion first

Okay, I figured out how to do this on Windows. In the .bat file or in cmd.exe or whatever you use, before running DiabloMiner, do SET GPU_DUMP_DEVICE_KERNEL=3. It should cause it to dump the .isa files.

The new binaries for windows he put up yesterday. 20MHash increase on the 6970's.

So yes new kernel is up give it a try, unless you have a 7970. Don't know what happened there.

Nope, its the new kernel as of the post that you quoted originally that says "Update: Committed the new kernel."

Er, 1503 on -v 2? Dude, you're not using the newest copy of DM. 1503 is what the old kernel got on -v 2 on 2.6.

And it explains your weird results with -v 2,1... the hash mater was broken at the time of that version for non-power of two -v, I told you the mhash meter was fine because I fixed it in above referenced commit.

Diablo what's up with GCN on the new miner. Do I need different flags only getting 30Mhash?

SDK bug that I've rammed into. Haven't quite figured out why its sucking, either.

[Joshwaa]

No biggie I will stay on the old version till you get round to it. Would love to see you squeeze more out of GCN though.

[DiabloD3]

Update: Remove -vs, -b, add -na for no array mode, set min fps to 0.1, and make loops work better.

[DiabloD3]

So, -na fixes it on GCN, but it incurs an estimate 13% performance loss (at least, if the ops on my 5850 are any indication).

Goddamnit AMD.

The score thus far:
vliw5: 1% slower vs old kernel on 2.1
vliw4: 3-5% faster vs old kernel on 2/42.5
gcn: 1% faster vs old on 2.6

Seriously, goddamnit AMD.

New App fixes it from 12.2 drivers. (898.1)

EDIT: Picked up 5mh/s too.

Radeon users: Catalyst 11.6 + SDK 2.1 seems to be the golden combination for 4xxx and 5xxx miners.

Is this referring to the whole Catalyst suite including the OpenCL, Display, and ATI Integrated Drivers? Or just the actual program? Apologies if it's a n00b question.

Catalyst didn't used to come with the SDK, it does now. That text is out of date due to the new kernel, its now 12.2 is recommended, use the SDK that comes with it.

Confirmed! Same here too. Diablo what is this -na flag u speak of? I do not have that option.

Don't bother with it, 12.2 fixes it. Also, if you don't have -na, you're not using the newest version of DM.

12.2 seems magical.  Updated an old p4 box from 12.1 to 12.2 and gained 18mhash, from 262 to 280.

Using -v 2 -w 256

Compared to my 5850@960, that'd be 360 and 384 mhash respectively. I'm getting 393. I have hopes for 12.2, but are you sure you're using the newest version of DiabloMiner?

I do have the latest, just updated to be sure and still at 282mhash.  This system is an old pentium 4, and just running off the cheap Dell power supply so I can't push the card much without crashing.  Anything above 900mhz core seems to result in crashes.

I have 2 systems at home with 2X 5830s each, and they do better mhash per card, even at similar clock speeds.  I think I'm hitting a limitation in this box due to the old chipset or something.

Well, on 12.1, it seems that a 5830 at 900mhz should get 287 or so. Are your systems at home doing that, or are they doing better on 12.2?

[chiropteran]

Systems at home are still on 12.1, sometime in the next 8-12 hours I'll have a chance to update them and report on the changes.

Dude, you're not using the newest copy of DM.
