Well what you posted and what your picture shows is very different. You stated you had a pair of 970's. Then said one was slower than the other. That made no sense because both are 970's.

But your picture shows 3 cards of indeterminate type. If the third card is different, slower or faster than the 970 pair, you will have to use the use_all_gpus parameter in cc_config.

You should never share PCIe cables between cards. A card needs either 1 or 2 cables directly from the power supply to satisfy the power requirements of the card.

You say one card is not showing any load probably is because it is power limiting itself because of insufficient input PCIe power.

First thing you should always check is "do all cards get detected by BOINC at startup in the Log"? If not, investigate why. Drivers not loaded usually is the issue.

Running 2 at a time on both cards with 290.53, I averaged around 790 seconds or so.

That is 1 GTX460/768 and 1 GTX560/1024.

Well Ok I see someone else has gone all Beta or maybe that should be Alpha, I'm getting 97-98% cpu use(295) and about 78%(285) while doing a gpu app.

It's yet another Nvidia driver problem introduced in 270.something

I've updated all of the separation applications to 1.00. For changes people might care about,

- The old CAL version is gone; it's replaced with the OpenCL application. On AMD/ATI GPUs (older than 79xx) it is using some hackery to use the same IL kernel as before so it should be as fast. However this also means the Radeon 38xx cards aren't supported with new stuff.

- Radeon 79xx stuff should work

- The occasional validate errors from empty / truncated stderr should stop

- AVX will be used if available on Linux and Windows (64 bit only for Windows)

- I've increased the default GPU target frequency so GPU stuff should make things less laggy on average. You can now also configure this with the web preferences now so you don't need to use app_info stuff if you want to play with that.

- Partial workaround with high CPU usage with recent Nvidia drivers.*

As usual post problems you run into here.



* It should cut down on the CPU usage a bit while not sacrificing too much. I would recommend not using it unless you are very unhappy with the CPU usage on Nvidia. There are options to change the polling mode if you want to lower the CPU usage further while not slowing it down. (--gpu-wait-factor (default = 0.75) and --gpu-polling-mode (default = - 2) work similarly to how they did with the old CAL one, but slightly different). With the default of -2 it will use mode -1 unless it is an Nvidia driver newer than the one that introduced the high CPU issue, where it will use mode 0. Mode -1 uses the correct waiting method, mode 0 use the correct waiting method with an initial sleep based on time estimates, and modes > 0 are a polling period in milliseconds. The wait factor is a sort of correction of the time estimate used for the initial wait. The default is 0.75, to wait for 75% of the estimated time before trying to poll.

I'm getting "feeder not running" error?

Im not sure if GPUGRID supports Fermi, but I know Folding@home does(beta atleast)although its not a BOINC based project http://folding.typepad.com/news/2010/05/open-beta-release-of-the-gpu3-clientcore.html

Yep, since Newegg is based in California, you have to pay tax.

I don't since I am across the border in Arizona.

And of course Amazon is not based in California.

Correct, I'm using a 5830, also the 4770 can do MW, too. I have a couple of those also doing MW.

I am using a 5830 as well, I have also seen someone using a 4730 on Milkyway as well.

Right now the card that I bought for $250 is selling for $240+free shipping+$15 rebate at Sapphire 5830 @ newegg.

ATI's HD 3850, 3870, 4850, 4870, 4890, 5850, 5870.

HD5770 says it does not do dp.
But like allways i dis agree with my hardware.
I pay for it so it does what i tell it to do.
I know the Terrascale2 GPU knows DP.
Will find out working on bios.
ah well now i am here might as well get my RAC up a lil....
