1  Bitcoin / Mining software (miners) / Re: 12.3 WHQL release ... ) on: March 31, 2012, 07:03:06 AM
Im using the 12.3 WHQL driver, still able to underclock memory to 200 Mhz (optimal speed), Core Clock is now at 1020 Mhz

hashing away at 457 Mhash/s on my single 6970 using vectors (77 degrees Celsius for temperature)

Also I'm using full release OpenCL 1.2 driver, but the only difference I noticed is more stability. Used to have my core clock at 1015 Mhz

What hashrates is everyone else getting that are so bad with new drivers?

Would you be interested in integrating my vectors3 method into phoenix 2?

I've been testing it with phoenix 2 lately and I'm getting some good results

I prefer to use result.s0 and such anyways, but I don't use the offset feature as it only lowers 1 APU but raises GPR making the card run hotter. Anyways, I found time to fix it and get it working, all three outputs are good. I was mistaken with the output buffer since there is no (hi - 3) with vectors 3 as there is no result.w

So, now it correctly reports (lo - 1), (hi -1), or (lo - 3). Does anyone want to try it out?

I am was just putting that there for reference not sure if it's in older versions? I got it working fine but there is something messed up with the output buffer it always says it's "lo - 3". Maybe I should stick with outputting as ulong? Why is it like that exactly, I tried doing a global output of uint3 which still works, but result.z will sometimes say difficulty is less then 1 (it's just barely outside the range too). I have no problem with result.x or result.y tho

What about using atomic counters for the statistics part?

uint3 is in there, but this is how it's listed

/* cl_uint3 is identical in size, alignment and behavior to cl_uint4. See section 6.1.5. */
typedef  cl_uint4  cl_uint3;

Anyways I'm still getting more init errors that have nothing to do with ratedivisor, gonna try a different version of phoenix

You'd think it would be better to use vectors4, but the ALUs shoot up to over 3000

That is absolutely not true. Both Diablo and I have spent an awful lot of time optimising for this SDK and still are doing so.

I did not mean to offend you or diablo, as you say you guys are actually still optimizing with new SDK which is awesome. I just see a lot of people sticking with older SDK because they assume it's slower

Why can't you just init as a uint3 in the first place?  Did you not change the python init file to handle the uint3 as of yet?

I did change the python init file, but just realized I accidentally set rateDivisor = 3 out of habit, and it's supposed to be 4 since you're supposed to treat uint3 as a uint4. It should work like that, but I'll finish testing tomorrow

You can't init as a uint3 in the first place because there is no definition for a true "uint3" in that sense, it's just a stripped down uint4 (last value is thrown out or used as a placeholder). I'm gonna work on it more tomorrow, but once I get it working this should give a 10% increase over uint2. It only uses ~920 ALUs so far
9  Bitcoin / Pools / Re: [1437 GH/s] Slush's Pool (mining.bitcoin.cz); supporting p2sh! on: February 27, 2012, 09:55:18 AM
I Found my first block too on slush during a 5 hour marathon, or right after. How do I check in block explorer my hash that found the block? Or how do I recognize it's from me?

If you don't log submitted shares, there's no way to check in blockexplorer which block you mined. If you're loggin submitted shares, then sha256(sha256(submitted_data)) == block hash on blockexplorer.

oh nice, why does it need to call sha256 function twice though?

Would I have to be logging in verbose mode?

lmao the readings are correct, I can show you a picture. how else would I be getting 455 Mhash/s if it was stock and how would my temperature still be 75 celcius? I have checked gpu-z before as well, but mainly to look at the other readings.

It's all thanks to msi afterburner, I can disable powerplay and clock ram as low as I want, as long as its 2.2.0 beta 10 or below. They messed something up with newer versions.

The Mhash/s isn't even that important I watch it for 5 minutes every now and then to make sure it's putting out at least 7 shares/min. It ranges from 5-14 depending on how the pool's LP is performing.

There are so many optimizations possible with the new sdk it sucks everyone is staying away from it, I'm testing a really nice one I found that might be able to give a 10% boost overall, but I haven't had anyone else test it yet so I don't know.

Okay so explain how my 6970 cayman card is running at 1015mhz core and 200 mhz memory with sdk 2.6? phatk v2 w128 gives me ~455 Mhash/s
12  Bitcoin / Mining software (miners) / Re: Best amd driver and sdk + miner combo for windows 7 with 5970's? on: February 27, 2012, 12:35:38 AM
No your just missing the point I was being sarcastic 5 posts ago. It's called a rhetorical question. The point being there is nothing wrong with sdk 2.6
13  Bitcoin / Mining software (miners) / Re: Best amd driver and sdk + miner combo for windows 7 with 5970's? on: February 27, 2012, 12:28:36 AM
Okay so as you said before "driver doesn't matter" because it's "not the same" even if there are newer runtimes bundled they don't matter. It's apparently unthinkable someone can install whatever part is bundled with it. That was very helpful advice.

You do realize the 2.6 sdk doesn't have latest runtime right? Nevermind drivers don't matter
14  Bitcoin / Mining software (miners) / Re: Best amd driver and sdk + miner combo for windows 7 with 5970's? on: February 26, 2012, 11:59:30 PM
I was being rhetorical... thanks. Runtime can expose new features of sdk so it can affect efficiency

Which once again ISN'T THE DRIVER.  Driver =/= runtime.  So yes runtime/SDK can affect performance.  Nobody has said otherwise.  The driver though isn't the runtime.

Runtime is included with driver... why are you trying to argue they're not the same when I never said that. All I was pointing out is the runtime can affect efficiency. Is it not already obvious it's not the same lol
15  Bitcoin / Mining software (miners) / Re: Best amd driver and sdk + miner combo for windows 7 with 5970's? on: February 26, 2012, 11:23:48 PM
Also, how do the driver not matter? It includes an updated runtime

You just answered your own question.

Just because AMD bundled the runtime & driver together doesn't make them the same thing.

I run 11.12 w/ SDK 2.1. 

Driver =/= runtime.
Driver doesn't affect OpenCL efficiency.

I was being rhetorical... thanks. Runtime can expose new features of sdk so it can affect efficiency

I got vectors3 working in case you're curious, speed is amazing : O

More details please Wink ... used GPU, which kernel. I never got that working with Phoenix.
And what means "amazing" Cheesy?

Dia

Was using your latest kernel with phoenix 2  rc1 on a cayman 6970 cat 12.3

New opencl version has built in support for uint3 so it might even work with your older version. It's basically just doing a typedef uint4 uint3, and it just assigns a 0 for last value of uint3 to ignore 'w'. The problem with your old kernel is you need to initialize uint3 as a uint4 first

Speed is good because you basically get to run vectors4 (vectors3) with less alu's. Even tho 'w' is not used finding x, y, and z nonces occurs much more frequently anyways
17  Bitcoin / Mining software (miners) / Re: Phoenix 2 beta discussion on: February 26, 2012, 09:36:11 AM
oh sorry.. so i was going through some of the newer python methods

platform="None" is depracated now, maybe should just get rid of checking for platform and just check for device. I think platform has a function that looks it up anyways.

Also the "is_blocking" is defaulted to true, so wouldn't it be better to set it to false on the enqueue_write_buffer as well?
18  Bitcoin / Mining software (miners) / Re: Best amd driver and sdk + miner combo for windows 7 with 5970's? on: February 25, 2012, 09:10:32 PM
That's really not true. I have memclock @ 200 and hashes are faster if you make proper changes to the miner. However, if you're using an outdated miner then sure it will act like that

Also, how do the driver not matter? It includes an updated runtime
19  Bitcoin / Mining software (miners) / Re: Phoenix 2 beta discussion on: February 25, 2012, 09:02:34 PM
Hmm, RC1 works flawlessly. I tried RC2 but it's bugged bad? I thought it might have been incompatible with sdk 2.1 (wont hash at all), so I tried 2.6. It has a different error, but it hashes slow compared to 2.6, and I refuse to use 2.6 and be forced to use high memory clocks and waste power.

back to using rc1 until bug is fixed.

A fix for this bug has been pushed to the Git repo.

https://raw.github.com/phoenix2/phoenix/9083008563fc6cffae99627e32ef8c39abf34859/phoenix2/plugins/opencl/__init__.py

why was self.f[8] taken out? It's working better for me with the old one
