Thanks ETA, that is great info, I didn´t know.
The memory use is set to 90% in use or idle.

I leave the Alienware at rest for a week. I will replace it original liquid cooler and the 2 AMD´s 5870 again and make the BIOS change you said.
Thanks I am really happy with this information!

Regarding your GTX550Ti: MW can take quite a beating, GPU-clock-wise. And especially on nVidias it's using only a tiny fraction of their hardware (hence it's quite slow on most nVidias), generating not much heat. I'm not surprised the card can take higher clocks at MW than at GG.

BTW: when ever a driver reset happens in newer nVidia drivers the GPU stays in fail-safe mode (the 400 MHz in your case). I have not yet found a way around this other than rebooting.

Not long ago I was down to 4 NVidias and was seriously considering dumping those. At most GPU projects the ATI/AMD cards are simply much more powerful and efficient. Then I came back to GPUGrid to give it another try. Now I'm working back up to a 50/50 ATI(AMD)/NVidia ratio again. The programming ability here is questionable (IMO) but the scientific results are compelling. I just wish they would ask for some help in getting the OpenCL app working. People can't be experts at everything. I've been seeing horror stories about the recent NV drivers and it's kind of strange: it used to be that NV drivers were solid and ATI drivers questionable. Lately I've been having luck installing the latest ATI and holding back on NV. To make a long ramble a bit shorter: I've stuck with 310.90 NV and am having no particular problems.

Instead of trying to run the 550Ti @974MHz I would set it manually to reference values of 900MHz for the GPU and 4104MHz for the GDDR5.

Boinc's values sometimes reset after a bad system crash, at which point it might be an idea to reinstall Boinc and have a serious look at temps.

Periform's Speccy allows you to see GPU, CPU and other component temperatures all from the one app.

I've had one system crash since editing the registry and no driver restarts - it works for me.

I had the opposite with Milkyway. Two AMD HD5870 running with one failure in every 30 WU, after Doc T. made a change it the app. But according to the fora it was at my end. Then I set the old but power horse GTX285 on the project, and thus not the open CL app and then 600 WU´s in a row without failures. With Einstein and Albert there are also few Open Cl that don´t validate, cuda only one failure due to my fault I did not suspend when restart.

Thanks, I will try that right away. Up to the warm attic.

If you had better success on MW with the GTX 285 than with your HD 5870, you had a major setup problem. I had virtually no failures on MW. Don't run it anymore since hitting my 500,000,000 credit target. The HD 5870 is (at least was when I was running it) is so much faster and more efficient than the GTX 285 at DP, it's not even a comparison.

Yes still is almost 10 times faster at Milkyway. Due to the short runtime a great project to experiment.
By the way not only me, I have checked and saw a lot of errors to validate even on 6xxx and 7xxx AMD cards.

Well I removed everything from EVGA and nVidia and installed the latest drivers. Now the Einstein WU is finishing with GPU clock steady at 951MHz and temp of 66°C.
Kernel times are low now as well. See tomorrow how it went.

Speccy has higher temperatures then Core Temp. But I have that said earlier, all these programs vary with their readings. But a CPU of around 50°C is not bad.

After a few days with problems, installing and de-installing I must admit that the old T7400 where we had our thoughts about, does it well with the GTX660 at 65-66°C and steady clock. The two Xeons keep quite cool with 50-65°C (passive coolers, with a fan at little distance from the two massive aluminum blocks), at 360-370Watt in total. I become attached to this system ;-)

Greetings from TJ

My three cuda capable GPU's are all crunching for GG so I am happy. However now the weather turns hot, with rising ambient temperatures :(

One question: what does is say that kernel times are high(er)? For most rigs they are low, near the bottom. At times I see them climbing to around 1/4, 1/3 in the window of CPU usage, you know what I mean.

Greetings from TJ

If a CPU cooler fits on an AMD3 will it fit on an AMD3+ as well?
Idea was a Zalman but I like the Cooler Master V8.

Yep, same mounting system.

My last idea for today. I want to contribute to GG with more then the GTX285, so bought a GTX660, but didn´t work out well. The story is known.
Now I need a new rig to fit two 660´s, but I also bought the refurbished T7400 for less.
I can buy a GTX770 for 390€ and put it in the T7400 as it has 1 8-pin and 2 6-pin power adapters.
Then the new PC can be made in winter and probably prices have dropped as well.
Good idea or not?

Sweet dreams.

Greetings from TJ

That's more of a put off than a solution. The best solution IMO is to get rid of your old power hungry hardware and replace it with a cheap system (basic CPU, motherboard with two PCIE slots) and kit it out with a good PSU and whatever GPU(s) you want. I don't think there are going to be many new NVidia cards any time soon (possibly a few revisions). While i3 4000series Intel and AMD Kaveri's are likely before the end of the year, these will be low to mid range (sitting on the fence) CPU's. You have to decide if you want to buy a fairly power hungry 8core AMD, invest heavily in an Intel CPU, or neither. If neither appeals to you, just forget about CPU crunching and concentrate on where it's at, the GPU. A basic CPU and motherboard with a good GPU will be cheap to buy, cheap to run, do lots of good work and get you lots of Boinc credits.

That makes a lot of sense. Especially since you'd "loose" 2 threads feeding the GPUs at GPU-Grid anyway, so there's less benefit of making these cores fast.

Scanning for our furry friends since Jan 2002

With temperatures rising I need to power down my rigs. But I got a GTX770 today and wanted to put in in the i7 with a (faulty XFX MOBO). After a lot of installing and booting it worked. Better than with the 660 from EVGA that didn´t work. This one is from ASUS. Not the brand as first choice of mine, but I thought that might work in the old rig. I must say I like the software with it. You can see everything, change the order of it and do i.e. setting for clock speed, fan.
This one seems to work with the XFX MOBO, system is more responsive and not yet slowing down. However windows seem to freeze at the place where they first appeared after dragging them somewhere else. Using a window as an eraser over the screen will clear things up, if you know what I mean. So not optimal. I will try in in the old T7400 later when it becomes cooler.
The 770 is now doing Milkyway as a test and goes smooth. When finished I set it to GPUGRID with all applications. See how that goes overnight. Tomorrow becomes even warmer so I must it shut down than as well.

Edit: one thing though, the i7 with the 770 has its kernel times almost the same as CPU usage, other my other rigs have low kernel times. Unfortunately none has yet explained what this means/what the issue could be.

Greetings from TJ

Its not working properly either. The 770 in the i7 (with XFX MOBO) has done 52% in 8.5 hours. That can't be right, seeing the results of other 770's. I will let it finish and then put it in the T7400 and will consider the XFX PC as scrap, I can use some parts of it later.

Greetings from TJ

Well the 8-pin power plug on a Dell T7400 is not the same as a 8-pin power plug from a EVGA PSU. It is white and is fitted on the same wires as the 6-pins power plug for GPU. The other 6-pins plug has not this extra plug.
So the GTX770 won't fit in my workhorse. Its in its box again waiting for a new rig. So RAC will gradually decline, not because I am leaving the project but because of hardware issues.

Provided the PSU can support the card, can't you use a molex-to-PCIe adaptor? There must be a spare molex or two dangling in there.

Those adapters can cause more problems in the long term than they can solve straight off.

More over there is only one free. I can replace the PSU, but I am building a new one earlier than planned so that is not an option right a way.
