AMD Catalyst 12.4 Released today. Thoughts?

[wazoo42]

Thanks for the link deepceleron. For my 5830s and 5770s all I had to do was switch VECTORS to VECTORS4 to get the max hash rate. The other params are BFI_INT, FASTLOOP, and WORKSIZE=128.

wazoo42 whats your memory/clock speed at?

After months of seeing threads like this where a new driver version comes out and people report horrible performance decreases, I have to say that I have never experienced the same.  For one, in the cgminer documentation it tells you to delete the *.bin file after every driver update or cgminer update.  I'm suspecting most people don't do that and report bad numbers, even the people who say "YEAH I DELETED THE KERNEL BIN FILES!".  Reminds me of people who call me at the help desk and go "YEAH, I RESTARTED 62 TIMES, STILL DOESN'T WORK!" and then you reboot their computer once and *magically* everything is working again.

The other thing I have to note is that I have found that driver versions don't mean shit when it comes to performance mining.  What really matters is the OpenCL DLL versions.  I don't care if you have Catalyst 1.1 or Catalyst 200,000,000.11923456.  What is your OpenCL DLL version?

I can tell you that I am running the OpenCL version that people are reporting in this thread on 2 5830's and a 7970 and my performance is exactly the same as 10 driver versions and 3 OpenCL versions before that.  If you were to believe everyone who says that each new driver release decreases performance, we would all be mining at 1MH/s by now.

12.4 drivers FUCKED ME OFFLINE for two days... Nothing good comes from them, Just wait for 12.5

You shouldn't have a problem pushing 5830's a little harder if you wanted to.  I am running 5 Saphire Extreme's of them 4 are stable at 1000core 300mem, -I 8 -w 256 cgminer (default version in BAMT) and those are steady at 322Mhs, however 1 of them will only do 920 core. Others go beyond 1000 core but mine crash when going above, from what I have seen and read 1000 should be reliable for most cards. No reason to have mem run that high, every watt counts.

Wow, why are you using such high memory clocks? That is sucking a huge amount of electricity and causing you to have higher temperatures and losing money. Underclock your memory and stop using shitty 2.6 SDK. Use 2.1. I get 294 mhash @ 900/355 using 2.1 SDK.

I've seen you QQ and bash 12.4 in about 10 different threads.  I'm mining on 12.4 (read: OpenCL 923.1), with a 7970 (and some 5830's), on Windows 8 -- which is supposed to not work at all.  Guess what?  It's been rock stable and faster than ever.  Also, 12.5 is already out, leaked beta downloads everywhere.

"i've seen you Quit Crying and bash 12.4 in about 10-" No, I referanced my own thread in the CG miner thread, In One other thread than that one, I bash 12.4, So This one makes three. Also, Im glad that your 7970 is working great with your windows 8 alongside the 12.4, Not all of us are running Such new components

I concur with 12.4, used cleaner to wipe old and install.  It would appear all is well until you happen to need OpenCL, installer says nothing about it like previous ones did, it should be installed behind the scenes but no cards are recognized for me, 12.3 was fine.

Time to roll back.

[scifimike12]

All I can say is that this driver was horrible with my 7xxx cards.  Cut the hash rate by half and I'd get an occasional BSOD (ATI related).  Used ATIMan Uninstaller and installed 12.3, was able to mine without any issues.  But I still cannot control the memory clocks on any of my cards with CGMiner or MSI Afterburner.

Hey I just noticed that the new drivers were released today.  I'm going to give them a shot right now and I'll let you know if there are any improvements.

My only thought: Don't go into the light!

i re-acquired some sapphire 5830's and I've been running them at 850/195 @ 1.063v, 128 worksize, ~285mhash each.  ambient temp is probably around 100oF.  the voltage drop dumped them from around 67-68oC to about 63oC

Hmm thats a full 8 mhash more than what I would project for 1120 SP's at 850MHz.. Whats your OS/driver/SDK/miner/kernel/settings?
