Updated from 2011-07-11 to 2011-07-17 kernel. Hash rate increased from 325 to 327 on 6950, and from 280 to 281 on 6870 all at stock clocks. Not a big increase but it's always nice to have a few mhashes for free. Keep up good work!

Can you make another version that includes all the recent changes and __init__.py does not need to changed?
thanks

I get lots of 'unusual opencl behavior. hardware problem?' on the latest version, using a fresh Catalyst 11.6 driver (not CPU buggy hotfix) on WinXP on two different miners, going back to stock phoenix and 07-11 kernel is fine.

Why?  Just unzip in the kernels/phatk/ directory.

Find the above useful?  Send tips to 1KjoJihf7GWHWeQFhDmaw4g7xorkmD13u

no sure your reasoning, but if you want that, just grab the 7-11 version.. the version before this latest.

You dont gain all that much from the changes in __init__.py if you really want to do with out, you wont be shooting yourself in the foot. So grab the last version.


Personally I appreciate even the smallest increase.. so thanks for the work

Why?  Just unzip in the kernels/phatk/ directory.

Main reason is some people like to use this kernel with poclbm. The 7-11 works, but the newest doesn't because it requires changes in __init__.py which is specific to phoenix. BOARBEAR is asking for a version that includes all the additional improvements since 7-11 that doesn't require any changes to __init__.py.

It is impossible to create a version of this kernel that works without modifications in the main miner software. As I wrote, there are values and variables, that the kernel uses and which are precalculated in the miner software and then passed as parameters to the kernel. A miner, which doesn't pass the required parameters will not work without beeing modified, sorry.

You guys are free to mod the kernel for yourself to revert the changes, which require a modded miner software and only take the ones, which can work without.

I have never seen that message during my tests with the release version of the kernel. What OS, which SDK are you on?

I wonder if he copied over the init.py file.

Yes I copied over the init file, because without it it won't even run.  Windows 7 64-bit, Catalyst 11.5, Stream 2.4.  Haven't had this message pop up with any other version of phatk kernel, nor any other kernel for that matter.

I had the same issue under windows which magically went away when I switched to Linux.

I had the same issue on my 5850, but when I took 5Mhz off my overclock the error went away, guessing it was picking up some errors from being pushed harder?

I'm on Linux and I'm still able to get these error messages, even with earlier versions of the phatk patch from this thread.  For me they start happening if my clocks are too high and become more frequenty as I increase the clocks.

For my 5850 at stock volts, 1015MHz doesn't generate any errors and with 1020 MHz they are very occasional but become more frequent as I ramp up to 1035MHz (my card always freezes at 1040MHz).

When I overvolted my 5850 to 1.25V and took it to 1110 MHz for 3 hours I got a few but noticed that I was generating good shares with the same OpenCL work request as was throwing errors so it seems the error doesn't invalidate the whole second and likely just a very small portion of it.  I have a screenshot here.

At lower voltages I never see these errors.  Either the card runs error free or crashes and the MHz line dividing these two states is pretty fine in my experience.

It's interesting that the kernel version might affect the frequency of such errors but they don't bother me.

Thanks for this latest kernel patch Diapolo.  My clock rates increased by 0.3 MH/s each.  2x5850: 722.2 MH/s -> 722.8 MH/s.  I'll send another small tip.

Very nice posting with relevant information to all who encounter this error. Thanks for sharing Smiley. I never had this error, because my 5830 clocks were (and are) never above 1000 MHz for the chip, so it seems logical to me.

I think I jumped the gun.  I believe I am having a real hardware problem.  It's only on one card, the hotter one of the group, and it's overclocked and over-volted to all hell.  I think what happened is that these errors were hidden from the console until this new kernel update!  If that's the case, kudos for making the errors work! haha.

Not necessarely. I had the same problem with a card in previous versions of the kernel. After 20 minutes it would produce that message in phoenix or would crash poclbm. But with exactly the same configuration and later kernels it was solved, even when it was producing higher hashing rates. I am not sure why it happens exactly.

my stales are at / shares 4234 / stale (7, 0.17%) / after the latest version using AOCLBF  on 2 5850's one running at 840/300 and 1000/300 the latter is because of getting a card with a crappy part number from sapphire

what I meant was, excluding the changes that needs the modification of __init__.py can you release a version that has all the other changes?
