Well I didn't get the Phoenix miner to go any faster than 120 M/hs.

Post your command line.

Here's mine (on Windows. In linux I had to set DEVICE to 1), for a 5850:

phoenix -u blahblahblah DEVICE=0 VECTORS AGGRESSION=11 WORKSIZE=128 BFI_INT

./phoenix.py -u http://username:[email protected]:8332 -k poclbm VECTORS FASTLOOP BFI_INT PLATFORM=0 DEVICE=1 AGRESSION=8 WORKSIZE=128

Note that these are the last settings I tried. I have adjusted AGRESSION (8 to 13) while having WORKSIZE=64 and WORKSIZE=128 with little effect on the hash rate (and removed the FASTLOOP parameter for AGRESSIONS above 8 after trying them all with the FASTLOOP parameter)

I don't know if this is odd or not but if I put an invalid device id it then shows:

AMD Athlont(tm) II x2 245 Processor

Sapphire - 1GB, GDDR5. My PCI-e slot is 16x1 2.0, not 2.1 (if it makes any diff)

My cards are Asus and Visiontek so I can't say for sure if it's different.

The board they are on is 5 years old so I'm sure it's not 2.1, and there's only 1 x16 slot, the other 2 are x8 and x4 and work without a problem.

fglrx 8.801 (fglrx, fglrx-amdcccle, fglrx-modaliases), 2.1 SDK

Thanks for the help here. I do have AMDOverDriveCtl version 1.1.4 but I haven't applied any profile or started using that as of yet.

That's crazy. I can't believe that there is that much difference in performance between manufacturers. What's the brand of your card?

I am sure I wasn't running another miner and that I had the proper device id. I'm on ubuntu 10.10 x64. I seem to have something not quite figured out since the new poclbm instantly gave me 30M/hs more performance but I never found decent settings for phoenix to hardly match half that performance. I also haven't been able to keep from freezing up with memclock under 1000. Obviously I have issue's and am losing out on at least 20 M/hs.

What fglrx packages and SDK are you using?

I found that WORKSIZE slowed my card down with phoenix. It seems to do just fine leaving that option off.

My card didn't like the mem clock below 1000 either. I had to leave it at 1000 until I got AMDOverDriveCtl working.

Well I didn't get the Phoenix miner to go any faster than 120 M/hs. Strange. The good news is that I did download the new poclbm miner and am clocking my 5850 at 850,1000 now to get 325 M/Hs and it not only isn't freezing anymore but is running about 79.5 - 80 degrees now, down from around 82-84.

120? Are you sure you weren't running another miner at the same time? Are you on Windows.

I downloaded the new poclbm also and it runs at 350Mh/s. I'm going to race it side by side with most current snapshot of phoenix and see if there is any diffence in performance.

I was able to run the card at 850MHz all through last night. So it's just 900 MHz specifically that's giving me unhappy times. Maybe I should try 899 ...

50 MHz is a *huge* difference for stability. For instance, the last GPU I optimised will run just fine at 850 MHz, crash after a while at 860, and crash immediately at 870.

I'm at 850,1200 right now get 300 M/hs and it seems to be "holding".

300 seems low. Are you using phoenix with BFI_INT?

I'm getting 320 MH/s on Windows at 850, SDK 2.3, phoenix 1.3. Linux was getting slightly better figures (when it wasn't crashing ...).

I haven't tried SDK 2.1 on Windows yet. That might bring me closer to grndzero's glorious 360 MH/s. Grin

i'm pretty sure it is the Xorg process

Maybe. I tried ctrl+alt+backspace to no avail. Had to REISUB every time it locked up. The miner also stopped. I did not try SSH though. I might take another stab at getting Linux stable later.

Wow, then it's a trade off because before overclocking and lowering the mem clock I had to go to 875/1000 to get 300 Mh/s and at 900/1000 I was getting 317Mh/s with poclbm. phoenix and BFI_INT brought that up to 343.5Mh/s then once I added lowering the mem clock to 300 I got to 361Mh/s.

I don't know if you can do increments other than 25, but you can try it.

Also, in Windows it resets the driver when things go awry, instead of locking up like Ubuntu does. From there, it's back to normal (at 900MHz), except the miner (phoenix) has stopped because of the driver reset.

I came at it from the BIOS perspective since I set out to run it on Linux and hadn't seen anything about power management (and didn't really expect anything).

They have had a lot more time to perfect the ungodly things they can do to the cards in Windows, especially since Vista/7 managed to separate the kernel and video drivers a bit so it's more stable (relatively) and can reload the drivers without rebooting.

I have a XFX 5850 running at 900Mhz core and 1000Mhz Memory using unlocked MSI Afterburner. Works fine with no problems and I've run it a full day with out any issues.

My card has a BIOS limit of 775Mhz on the core. With MSI Afterburner I'm able to go beyond that. I'm not sure why this is or how MSI Afterburner does it without having to flash the BIOS to a 5870. Of course this only works in Windows and I am unaware of any program that will do this in Linux.

Eadem mutata resurgo

X server is not so happy to share GPU resources as windows with OClocking tools enabled... i'm pretty sure it is the Xorg process that is hanging but if you could ssh or otherwise remotely login you may find the OS is still up ... at least I did ... othertimes it really is the OS (kernel) that has crashed.

It is a real mess in linux because the x server is taking care of hardware control of the GPU's that are acting as compute nodes in this application but it is a different philosophy than what the x server was built todo (graphics display management) ...

I have purchased this same card a couple of days ago and am experiencing the same issue with Ubuntu 10.10 64bit. I tried simply flashing my board with it's most recent bios but that didn't help. I'm at 850,1200 right now get 300 M/hs and it seems to be "holding".

I ran in for the first day just fine at 875,1000 but then realized today that it locked up at midnight Sad

...lost about 10 hours of mining before I noticed the problem.

Hopefully these settings keep me stable. I think I'll skip the 11.04 upgrade and any others that come along. It seems any update just causes me pain and sorrow!

I'll report back if this continues to be stable with these settings and good luck!
