It finally work on my side !
Without optimisation, I got around 265000 khash/sec. I got an i7 920 oc to 3.6ghz with a radeon 5970. I'm gonna look to do some tweak to speed up this thing a bit Wink If you have any comment or something you want me to try don't hesitate. By the way, I've been running this thing tonight, and in 8 hours, my wallet is still at 0. Is it normal ? Do I need to restart it? Or it's just like the way it should work, which mean it's still pretty long to generate? Thanks for your OpenCL gui Moo, I really appreciate it !

Malouin

P-S I think I only got 265000 khash/sec on my 5970 because i'm only using 1 heart. When I'm at the point I need to choose the device, I see 3 option, 0 = my cpu, and 1 and 2 is the same thing. is it possible ?

I'm pretty sure I can get the 500 by using my 2 heart, or maybe i'm totally wrong XD

The 4 that you see was just after I finished installing it. It was still downloading block. About the public or the test, I supose i'm on the public network. I simply did the bitcoin -server, and started the poclbm. While I was reading, I heard about a shared pool. Is it really that good ? If you have any info you can help me don't hesitate, I'm open to anything =) Btw i'm on irc ( Malouin ) presently if you wanna talk !

The miner should display 'bitcoin is downloading blocks...' until all blocks are downloaded. Please test. This was added in the SVN 163 patched client.

David, I removed usage of vectors. So the '-w 128' is not relevant anymore. Of course you can grab the vectors version from git and use it like before. It is really difficult to optimize for all possible devices. Current version is kind of best for all.

Tried the -f 35 and -w 128. I get around 270m khash/s. And yes, I can load 2 separate poclbm, using device 1 and device 2, both are doing around 268m khash/s. Total of 536m khash/s.

And yes, it display the bitcoin is downloading blocks... Thanks !

Update : I Oc'ed my 5970 GPU clock from 725 MHZ to 800 MHZ and my memory clock from 1000 to 1305MHZ.

I'm now at 295m on each heart, total of 590m. Everything seem to be fine, I will let you know about futur update and how much I can get with the 5970.

hehehe thanks guys =P

I was speaking with Art on irc today, and my next step will be to OC my 5970 from 800 to 910mhz. I should reach the 320mhash/s on each heart, which mean a big total of 640mhash/s.

I restarted my client at 15h30 EAST time, and will stop it tomorrow at the same time. It gonna give me some data to work on. After that, i'm going to OC it at 910mhz and see the result and report here with some screenshots.

bethel, what are 5870s showing at stock frequency (850 MHz)? Perhaps one of the cards throttles down?

Latest version has new parameter, -w, to set work group size. I have best results on 5770 with -w 128 -f 35.

Latest py2exe version is http://github.com/downloads/m0mchil/poclbm/poclbm.7z

Sorry for the late reply, I have been away for a while.

I found my problem and it was so simple it is silly. I had not yet enabled the -frames switch to crunch faster. I still don't know why one card was faster without the switch but they are about equal now.

As for the mhash @ 850mhz I get about 265mhps.

xxmalouinxx, what OS, SDK, and driver version are you on?

I can't seem to get my two cards to both run at the same time under Windows 7. Any hints?

Windows 7 Ultimate / ATI SDK 2.2 for Win7 64 / Catalyst 10.7

I got a radeon 5970, so I don't have 2 cards, but 2 hearts on it. Art got 4 cards on 1 motherboard doing this, I'm gonna ask him when I see him.

Davout : Yea it should work without any problem on linux. ArtForz actually use that.

Fergalish : the Nvidia GT240 got 385 Gflops, the radeon 5970 got 4640. If we base it on the fact that the 5970 got 230 000khash/s per core without being OC, it should be around 20 000 khash/s yes.
