i currently am using a fx8370 overclocked to 4.8ghz and 2x crossfired 290x's. my ave. work done is about 20k ..assuming that means 20k credit per day? if i look at some other peoples computers i see they are running a 8350s or 8370s with 1 or 2 video cards (usually less then a 290x) and their average credit is 50-60k(3 times higher).. someone please explain? i have 6 cores running 100% on seti plus both 290x's ..with my setup is 20k normal or is there something im doing wrong

There are optimized applications, that run faster than stock apps.
Also, you can setup to run multiple work units on a single Graphics Card, which produces more credits per hour than just running one.

Use 0.43b.

Please be aware, that you need to let your existing task run dry, as installing 0.43b will kill your already downloaded tasks.

Rasputin has part of it right. Optimized applications will help speed up the work on the graphic cards. But there is still a limiting factor that he didn't address.

I used to run AMD 8350. And what you need to remember is even thou it's a 8 core, it only has 4 floating points. What??

The 8 cores are trying to access only 4 areas. So 2 cores are both "Sharing" 1 floating point. Think of it like 2 people trying to pass thru a 1 person door. They both can't do it, so they have to take turns going thru it.

That's the problem with those chips. You would be better served to stop crunching on the CPU and instead run multiple work units on the GPUs. That way the CPU could support and feed the GPUs with work.

I'm not sure how many you could do on those cards since the GPU typically crunch faster than an CPU, it would more than make up for any lost work on the CPU.

Lunatics Installer v0.43b (64-bit) im assuming,,ill give it a try tomorrow after current tasks finish..changed setting to run on 4cores only for now. 70700gflops in 5mins on gpu ,70700gflops on cpu =1hour15mins.. normal?

Yes to Lunatics Installer v0.43b

I'm assuming you are running windows 64 bit? If so, then yes.

changed setting to run on 4cores only for now.

I'm not sure why you reduced CPU usage to 4. I would just stop CPU crunching and leave all the cores for the GPUs

How long to crunch? Yes, GPU are much faster than CPU. I would think your times are correct.

Once you get the Lunatics installed and running correctly, we can talk about doing more than 1 work unit per graphic card.

Congratulations on getting your 8370 to 4.8 Ghz. I ran out of cooling capacity on my 8370 and had to stop at 4.6 Ghz. What Zalster said is very true. I had been running 6 cores on my 8350 for a couple of years now and only produced a max of about 36K RAC crunching full time. After setting my CPU usage to only 50% or 4 cores, I have been able to get my RAC up to just under 30K RAC only for about 8 hours a day during daylight. I have seen a major benefit for keeping maximum CPU usage down to about 50%. Both CPU and GPU task completion times have reduced significantly. Only use 4 cores for CPU tasks and let the rest feed the GPUs. The GPUs will do the heavy lifting for bumping your RAC higher. I would try 2-3 tasks per GPU crunched at a time to see which is most efficient. I can get away with 3 tasks per card for MB tasks but only 2 tasks per card for AP tasks. Once winter gets here and I can run 24/7, I expect to get to about 45K RAC for each machine.

I think you are going to find there are Problems running more than One instance of Setiathome Multibeam on a Hawaii card in Windows 10. It's discussed in a couple of threads here and over on the Raccoon Lovers board. On RL one member went back to Windows 8.1 and the other put the card in a Linux machine. There are a few people having that problem.

We can't all run 4 GPUs per cruncher, Zalster. In your specific case, crunching on the CPU would add negligible RAC since your GPUs do the majority. In my case, the CPU can and does add to a good portion of the total RAC. I just figure if the CPU had to be on to feed my dual GPUs, might as well crunch on it. I don't see any significant improvement in completion times when using all my cores to feed the GPUs and not crunch on the CPU. I would suggest the OP try both conditions, no CPU crunching and 3 cores of CPU crunching to see what is best for him. I don't know anything about AMD GPUs and what they are capable of.

I forgot about the issues with the 290 cards. I had heard of problems with them running more than one task over at Einstein. Didn't know there were similar problems here at SETI. If you can only run one task per AMD GPU, then my advice to also run the CPU is even more valid since the total output would be greater. I'm just happy to not have tried AMD cards so far and have had no issues running Nvidia hardware.

ok thanks

i can get it to 5.1 stable but temps get to much for my h100i to manage ...5.0 keeps me on or 1 or 2 over the max temps...4.8 keeps me 10c under max on full load.. so i usually keep it at a nice safe 4.7 or 4.8

ok thanks

You might want to ask a couple of your new teammates about their experiences with Windows 10 and their Hawaii cards, http://setiathome.berkeley.edu/forum_forum.php?id=1315, woohoo and Zombu2, they've had a few.
Oh, Welcome aboard.

i also just ordered a Asus Crosshairs formula board(got a good deal) to upgrade from my m5a99x ...crossfire on dual x8 probably isnt helping anything and will run cooler so i can push the CPU futher. im going to slowly upgrade every component over a few weeks and eventually just build a new PC ( Wife wont realize what im doing until its finished lol)

team mates? oh you mean that raccoon thing haha ..they had lots of pictures of cute little raccoons so i just hit join team today..i really dont understand the point of teams for this

Regarding Bulldozer, Piledriver, Steamroller, and Excavator designs.. yes, one floating-point compute unit per 2-core module does make some cache-thrashing and resource contention.

On my FX-6100, I noticed that when using all six cores on various benchmarking scenarios, running all six cores only ends up with an overall boost of ~4x over a single thread.

Since then, I've been running my 6100 on 50% of the cores and that has kept the run-times of tasks as low as they would be if there was just one of them running, but it also keeps the run-times stable. I found when running all the cores, the run times not only increased by upwards of 30%, but there ended up being a large amount of variation in the average run-times as well.

It's all up to you, of course, but for these shared-FPU CPUs.. I prefer and recommend only crunching on half the cores. Less heat and less power consumption, and more stable and consistent run times, even if the overall productivity is slightly lower in the long-run.

Use 0.43b.

Please be aware, that you need to let your existing task run dry, as installing 0.43b will kill your already downloaded tasks.

Why do you say that? The installer is carefully designed to preserve existing work in the vast majority of cases, and certainly to preserve stock work (both running and ready to start) on first installation.

If you think you've found a bug, please report it - here will do.

To speed up the GPU`s add the following to the mb_cmdline_win_x86_SSE_OpenCL_ATi_HD5.txt file.
