HCC GPU Launched.

[Snow Crash]

OK I just dropped in a 7850 but after installing latest driver from AMD for WinXP 32 (12.6?) GPUz says I don't have OpenCL. What do I need to do now.

[Bun-Bun]

Quick google search

try older drivers. IIRC AMD dropped WinXP support in OpenCL support with AMD APP 2.7. catalyst 11.2-11.4 should be last one which have proper opencl support at WinXP

There is a solution in this thread....I think....I'm looking for it.

A 7xxx series card will not run on XP to my knowledge. Takes vista or higher. ATI stopped APP SDK support for XP after 12.1 I believe. I know 11.8 works (I'm using it on this XP with a 5830) but only on 5xxx and 6xxx series cards.

See post #393 and #395 in this thread.

little update, ccc 12.8 has no opencl support in win xp. it seems that 12.4 includes an opencl driver so I will try that!

so ccc 12.x versions don't have opencl support for winxp. and ccc 11.x versions don't have support for 7850. looks like i'm going to have to move the card to the slower win7 machine. oh well.

Thx for the homework werdwerdus ... I have a 7850 on the way and you've just saved me boatloads of time as I've never run ATI

Here is the posts he refered to.

Thanks, I'm brain burnt today forgot those posts. Guess I'll switch my Nvidia cards to the XP machine and put the 7850 on Win7

I thought you learned from my troubles... No support for 7xxx in win xp for opencl. video only.

Do you have this in your cc_config to run on both gpus?:

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

I didn't realize this was necessary. I have "report results immediately" in mine. Sooo now cc_config should look like this?

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
<report_results_immediately>1</report_results_immediately>
</options>
</cc_config>

You can set "report_results_immediately" back to 0 for this project to help the server strain.

And yes, if you want to use all the GPU Cards installed in your system, then set "use_all_gpus" to 1.

Finally after almost a full day of trouble free crunching 4 WUs on my 7870...

10/24/2012 ---- 0:004:10:31:41 ---- 493,673 ---- 2,166

Can't wait to see what a true full day gets me.

What was your final solution?

As Homer would say: "Doh!" I hadn't thought of that. Thanks.

[bluestang]

What was your final solution?

Uninstalled all AMD drivers/software, rebooted, ran driversweeper till nothing was there, rebooted, and installed 12.11 beta.

While i was at it I increased power limit to 50%, fan to 40%, and GPU Core to 1250.

Of course you probably just jinxed me and it will stall again shortly after I write this.

Regarding the WUs that get "stuck," I think I may have fixed it on my system. I changed my 2d clocks to match my 3d clocks on my 7850 and I haven't had a stuck WU in about 36 hours. Your power consumption will go up in a 24 hour period, but it shouldn't be too much more.

[bluestang]

By modifying the profiles XML file?

[kjeldoran]

By modifying the profiles XML file?

Yeah, under C:\Users\your username\AppData\Local\ATI\ACE. Just have to kill CCC.exe and MOM.exe before modifying the profile.xml. Restart CCC and you should have your changes done.

Something of a step change that I guess a whole bunch of folks are seeing.... Mine are in millions but SAM's....... will be in 10mill steps soon

This makes sense as why adding more threads makes it not get "stuck". With 8 threads running on a 7950 it never has a chance to get down to 2D clocks as it is always processing.

Hmm, makes sense, but even when running 4 threads on my 7850 I get times where I have 0% GPU utilization. I'm still going to keep my 2d clocks the same as my 3d clocks for that one time it is at 0%.

[Bun-Bun]

My 7950 rarely goes to 0%. Jumps between 85%-99% most of the time.

[bluestang]

I see they changed results time to "CPU Time / Elapsed Time (hours)" on the WGC Results Status page.

[werdwerdus]

I just replaced an i3-3220 with an i7-3770k (6th sig rig). I also removed two GT 240 gpus that were crunching HCC GPU. Will be interesting to see how the 7 threads of WCG on the cpu compare to the points output of the 2 GT 240 cpus!
