Bumped my hash rate from about 428 to 431 (3 MHash/s or 0.0696%), although previously I was using a customized kernel that has some of the same changes you've made so this increase is not representative.

Edit: XFX 5870 @ 950/315

Radix-The Decentralized Finance Protocol

The newest kernel gives an error on only 1 of my 4 cards. Phoenix says something about a kernel or OpenCL error and suggest that the card might be malfunctioning (and then keeps mining), and poclbm just crashes. The card is a ASUS 5870, but I have an identical model that works fine. The error might not happen for like 20 minutes. And the card apparently works perfectly since various pools accept the results from that card with no special extra-stales.

Also, I find it weird that the newest kernel seems to add some Watts of power consumption (I need to measure this propperly though).. Since its doing less operations and that way achieving a higher rate, shouldnt it consume the same?

i tried it on one of my 3 x 6990 mining rig - normally using poclbm with the phatk per GPU 408 MH/s - with your kernel per GPU 407 MH/s

This isn't exactly a fair comparison since phatk was specifically targeted at VLIW5 GPUs on SDK 2.4. A better comparison would be against phatk without this modification.

Too bad, but thanks for trying

. Perhaps a new version will be ready by the end of this week. But guys don´t expect a huge improvement. On my setup I get 0,5 - 1,5 MHash/s more than with 2011-07-03 kernel version (guess the puzzle reaches it's end ^^). I can´t work like I would like to because the AMD APP KernelAnalyzer doesn't work ... hoping for a new version!

Can somebody upload a version of the kernel we can extract natively in windows without downloading yet another compression/decompression app?

TIA

edit: Online decompression: wobzip.org

Seriously just get 7-zip and remove the rest, its free, open source and its default format .7z is probably the most effective lossless compression format commonly used.

winrar can unzip like everything.

And is Shareware ... but let's not start a packer discussion here an return on topic!

The kernel is that small I guess it wouldn't even need to be zipped. Download volume should not be that big.
But I really like 7-Zip, it's free and open source ... you should consider to install it as your default packer

Hi,

I offer my rapidshare account for the links. I would mark the files as trafficshare, meaning no popups, no wait time, nothing. Just like a normal download from, lets say any software website, click and go. You wouldn't even have to go to the rapidshare page.

And since we're talking about 4KB, I couldn't care less Wink

Try it:

I was already running the "#define Ma" optimized kernel, and this is good for another .5% on top of that.

Trying your kernel with poclbm miner now. Actually getting 62 on here vs 61 from Phoenix.

Update again: No issues on poclbm using your kernel so I guess it's Phoenix.

Dunno what the difference is between the 2 OpenCL wise. Setup, command queues, perhaps kernel result download or processing.
If you see a problem you should contact jedi95, perhaps he can clear this up?

Dia

I will look into it. GUIMiner has their own Phoenix and that may be related.

Hi! Just tested this, it did boost my 5850 @ 960/300/1.174v from 390 > 395. However, it seems to drop off to 380 all of a sudden like 3-4 seconds then back up to 395. Still, an increase, thanks for the work!

It's actually 05:22 now so duration is same but number of results is significantly less though total accepted is same. Hashrate is 57 vs 61 with your kernel.

Update: Some more results...seems like it may just be a phoenix thing with bitclockers. I will get some data from DM for reference but I may have to go ask in Phoenix/GUIMiner thread.

I have a really high reject rate with this kernel on my 4850. I've tried alternatively running this kernel and DiabloMiner. I'm getting about 30%-50% reject on your kernel vs 10% on DiabloMiner. Could just be bad luck. Right now it's 4 accepted and 5 rejected after 10 minutes.

I found when pool mining that most of my rejects came shortly after new work was pushed. As a result I had to try much longer test runs (3 hours or so) before coming to a conclusion about the miner's efficiency.

I'm aware of that, but I've had more rejects in the 10 minutes I'm running it than I've had all day. 411 shares, 22 stale. 13 of those are from testing with this kernel in the last 45 minutes or so.

I'm trying another pool and it's a bit better at 6 Accepted 2 Rejected. On bitclockers I was running at 300+ shares and 11 rejects with DM but getting the numbers above with the modded phatk kernel using phoenix. Trying it again.

Yes, after 45 minutes things look highly suspect to me. A good 3 hour test is useful for comparing different very-good setups but this tweak seems to have really hurt your accept/reject ratio. Let us know your best when you're done testing.
