Is the CPU overclocked? My athlon II x4 620 if overclocked to 3.3 (2.6 stock) will add 110-130w at full load to overall consumption. By the way, you can save a few watts if you downclock the video mem. Mine is at 150mhz (shaved off about 8w from stock) without any performance impact on the client.

If the setup is pretty basic, a 6850 can definitely pay for the crunching of a dual core cpu with a few cents left. Based on my local power rate of 18 cents per kw, that box will spend $0.9-$1 a day. Really depends on hardware.

My dream setup is 6-core cpu and 5870 crunching for boinc and a 5970 crunching for cash. If not crunching on cpu, a dual core cpu with 1 5970 assigned to boinc and 1 5970 assigned to C4C.

Try experimenting with the opencl sdk versions, 2.1, 2.2, and 2.3. My 4850 works best with the 2.1 while the 5670 is better with the 2.2. I can only assume that the 6850 is best partnered with the 2.3.

What's the wu/hr on the 6850? I'm guessing somewhere between 0.6 to 0.8. My 5670 at 5fps setting fluctuates between 0.34 and 0.37. According to my calculations based on the performance of the 5670, a 5850 can easily make 1 wu/hr.

When I started on the 4th week of february, the rate was fixed at 20 cents per wu. I only made a little cause I was skeptical that it might be some sort of scam an I might just be waisting power, so I only ran the client a few hrs each day. When I reached my first $10 and made the cashout, $9.31 appeared in my paypal account several minutes later. If I just took the plunge and run it 24/7 that week, I could have earned more.

My motherboard is a gigabyte 740g, I didnt like it much before due to the crappy IGP and no acc support. Now, i'm very pleased with it. The idle cpu power consumption of the athlon 620 is very low. Considering that the TDP of the 5670 @ stock is already 64w and is now running 990 core, total system draw is only 92w.
4) Message boards : Number crunching : help! customized app_info? [running specific GPU independently of project] (Message 11714)
Posted 2505 days ago by Haris Dublas
If its an AMD/NVIDIA mix, you can point the amd to a project and point the nvidia to another project.

Ex. AMD to MW/Collatz/DNETC
NVDIA to Primegrid/Seti

If only Collatz and MW and you are using multi-amd, you can try this:

Exclusion of GPUs: x (default none)
If a certain GPU should not be used by the app, one can exclude it. The GPU number has to be in
the range 0..31. The first GPU in the system has the number 0. This option can be used multiple
times. Per default, all supported ATI GPUs are used. Do not use it with an ATI aware BOINC client!
It should be ignored in that case. But there may be some unwanted side effects
.

Example:
<cmdline>x1 x2</cmdline>
The app will not use the second and the third GPU in the system.


Don't know if this is still possible with the current version of boinc and apps. I've made it work long ago using the 785g IGP to crunch Collatz and the 4850 to crunch only MW. I forgot what version of boinc I was using at that time, most likely pre 6.10.

On the client window, you will see the following:

Current Rate: "wu/hr" Session Duration: "time spent per session"
Completed this Session: # of wus completed Account Balance: $$$

Unfortunately the client cannot run as service yet or minimze to system tray, you can only minimize to the taskbar. There's a config file where you can set which gpu to use and how much utilization you want. You can mix different gpus per PC but cannot mix ATI/NVIDA. For 4000 series cards, its best to use opencl sdk 2.1 and 2.2 for the 5000 series. The 4850 performs almost the same as the 5670, I tried the 4650, the power consumed was more than it can earn (maybe viable if there are 3 or 4 per box). My 5670 clocked at 990/150 averages 0.335 wu/hr. If not doing anything with the CPU, my athlon 620 + 5670 only consumes 92w. So earns 4 cents and spends 1.69 cents (my local power rate is $0.18/kw) at the current rate of 0.122/wu. Last month the rate was 0.2, now the rate variable according to the work demand (dunno what). Highest so far was 0.132 5 days ago.

If I set the utilization to 98%, I can browse the internet. At 99-100, the screen lags so much, dragging or opening windows is a pain. At 96-97, I can watch movies up to 480 without hiccups. Below 95, I can play any game I want.

I agree with everything both you and Paul said!! I do not crunch solely for credits, I crunch for Science reasons, Team reasons, personal reasons etc, etc as most of us do. And yes my electric bill is WAAAAY too high too! I am actually selling some of my old pc memory so I can purchase a new everyday pc for me, I am thinking i7 but an AMD 6 core is enticing too! Right now I am using a dual core so either would be an upgrade. I do have 5 quad core machines but most are Boinc only machines that are not healthy enough to be everyday machines. They could be but currently have very small recycled hard drives in them, no cd drive etc, etc. Even their motherboards are cheapy ones just enough to run the quad core and a pci-e card, some can't even be expanded beyond 2 gig of ram!!


Or you can sign up to this site. They pay you to crunch something using their own client (not boinc). You can buy boards with multiple pcie slots and assign 1 gpu to their client. A 5970 can earn $150-$200 (the rate fluctuates) a month, this way while your cpu and other gpus crunch for boinc, 1 gpu will pay the electricity consumed by the whole PC (in short your boxes will be paying for itself). There's also a referral system, you can receive 2% of the work processed by the ones you referred. Uses opencl and the 2010 vcc++ runtimes. ATI performs better than NVIDIA there, they only started last month so I think they can still tweak their client more.

Is it okay advertising a site crunching for money like this Slicker? Just remove this post if it's not. The forum rules does say no commercial advertisements. I just thought it's a great way of making our crunching PCs earning a little to help pay the bills while still crunching boinc projects. I'm not saying to pack up and move all gpus to that site. Money was not the motivation when I started crunching after all. It's just that in some parts of the world, power cost is a bit high (about 18 cents per kw in my area, it was only 8 cents 5 years ago even though it comes from geothermal power).

I've been meaning to buy a couple of I7 or x6, the dual and quad cores credit production in WCG is just too small to be worth the electricity spent (especially the CEP units). But everytime I have something saved, some sort of emergency always crops up and poof I'm back to square one. Running boinc on several boxes around the house earns me an earfull from the wife everytime she caught a glimpse of the power bills (she just cant understand this hobby of ours, I literally have to hide the bills from her all the time).

Since my boards only support 1 pcie slot each, I decided to suspend boinc and let my gpus earn money for a while. Maybe in a few months, I can buy me a couple of high end machines that can outproduce all my other machines combined (cant sell the other machines, the wife and 2 kids use the 3). Maybe the wife will be less naggy if hers and the 2 kids machines are only powered on when they are using it. Then I can resume boinc and continue what I've been doing in the past five years.

If you want more credit/watt and not care about cpu crunching, get an I3 and MB with more PCIE slots and add another gpu. For example my athlon x4 620 OC'ed to 3.3ghz from idle to full load adds almost 110w to the total consumption. That 110w can power a 4850 or 5770 at full load, add a little more and its already enough for a 6850.

Seems primegrid apps work the cpu harder. My rig consumes 10-15w higher and higher temps compared to running WCG. Well, primegrid gives higher credit so I guess thats okay. :)

Posted 2684 days ago by Haris Dublas
Use Rivatuner or MSI Afterburner (based on rivatuner) to set your clocks, so you dont have to change your settings every reboot. Rivatuner at this time cannot recognize all 5000 series cards but can be easily fixed just by running RBE (Radeon Bios Editor). No need to edit or reprogram your card's bios, running RBE will tell you that it will change the config of Rivatuner to recognize your card.

Using Rivatuner, you can set your clocks to half or 1.5x of the default. So if your default clock is 800, you can set to 400 or 1200. If you want to set your mem clocks lower, just use GPU-Z to save your bios to a file then lower the default mem clock using RBE then flash your cards bios with the edited one using atiwinflash.

For some reason, I get invalids at MW if I set the mem of my 4850 to 400mhz. The 3850 will run the MW wus fine at 300mhz but it will add 10secs more to the runtime compared to the runtime with 1000mhz mem. Maybe because it only have gddr3 mem.

I am having most (but not all) GPU work-units fail on my machine (hostid=37541).

the failures all say no suitable GPU found. Example here:

http://boinc.thesonntags.com/collatz/result.php?resultid=48979782

Every now and again, however, a model will complete successfully. Example here:

http://boinc.thesonntags.com/collatz/result.php?resultid=48981452

Of over 360 models, only a handful have run successfully. What am I doing wrong?

Thanks.



Have you tried re-installing or upgrading your display drivers?

For fun i opted to run collatz on my cpu to see how long it will take to finish the initial numbers are scary :D
done 01:24:00 progress 14% time to finish 60 hours :D


When I tried it before, AX4 620@3GHZ takes about 12hrs +/- with the 64 bit app.

I think gigabyte has a 780g with 2 pcie slots, 780G-UD3 something.

I have no problem running IGP and discrete cards together. Tried it with ati xpress200 + 4650, 740G + 3850, 780G + 4850, 785G + 4850, nv8200 + 8500GT, and nv8200 + 5670. This way family members can browse the internet, do some light gaming, office works without affecting the crunching of the discrete cards.

Posted 2711 days ago by Haris Dublas
Download the ati 2.09 opt app and read the instructions.

In the cmdline of app_info, experiment with the "f" and "b" settings and lower the "w" setting if the gpu usage gets too low.

ex.
<cmdline>f100 w0.80 b2</cmdline>

With this setting I can play games like BF2, Warcraft 3 (DOTA), etc. without noticeable lag. Just try different settings until you find a tolerable or acceptable one.

Posted 2716 days ago by Haris Dublas
If you are also crunching on CPU (12 cores) and your cards have 2GB video mem each, its probably memory related. Try limiting the memory used by the app ("r" option in the cmdline of app_info).

BTW, set your video mem clocks to the highest setting possible. While MW doesn't need the bandwidth, Collatz needs it for for better performance.

Your 2.04 settings are very minimal that's why you have longer calculation times.

I think your 5570 can perform better. Most 5x00 series cards are good overclockers. My 5670 (400 SP, default clocks at 775/1000) now running at 1000/1150 performs the same as my 4850 (800 SP, clocks at 665/1200) here in Collatz.

I see, I thought the work was sent again and completed by somebody else before the deadline. I was alarmed when I saw all those red messages in boinc. :)

Now after checking the account and counting the total work reported today, everything's fine. Thanks for pointing it out. :)

Posted 2740 days ago by Haris Dublas
I had 40 finished tasks with no credit due to downtimes. The tasks didn't exceed the deadline but server refused to accept the finished tasks and reported that the WUs were already completed when server came back online.

There were also 20 resent lost results, I didnt reset that host. All tasks were completed with no errors. With 60 tasks, 15 hrs of work done by my 4850 was fruitless. :(

20) Message boards : Number crunching : Computation error on MacBook Pro (Message 8811)
Posted 2746 days ago by Haris Dublas
Upping the shaders produced an invalid result. The 2.03 and 2.04 cuda apps do work fine with just 64mb mem but an app_info is needed. Without the app_info, server wont send any work.

You can still get work without app_info but you have to set the mem to at least 128 before asking for work (reboot then change onboard gpu mem in the bios then ask for work then reboot then change back to 64mb). Too much bother. :)
