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?

Bitcoin / Mining software (miners) / Re: DiaKGCN kernel for CGMINER + Phoenix 2 (79XX / 78XX / 77XX / GCN) - 2012-02-20

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

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

Bitcoin / Pools / Re: [1437 GH/s] Slush's Pool (mining.bitcoin.cz); supporting p2sh!

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.

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

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 ... used GPU, which kernel. I never got that working with Phoenix. And what means "amazing" ? 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

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?
