1) Message boards : Number crunching : Windows 10 (Message 1591709)
Posted 1 day ago by Profile Bill GProject donor
Well I recently installed Windows 10 as an upgrade from Win 7. All went well with the exception that it installed Windows graphic drivers and SETI stopped working on the GPU. I just changed the drivers and the GPU is working again.

By the way, this is much better than Win 8.1 for my desktop (which I really did not like at all-I went back to Win 7 on all of them). It shows as Win 8.1 in my account for now.

This is a tech preview and not fully functional but what I see I am really liking.

By the way, all I did before doing the upgrade was to exit BOINC, it started up again on its own after to upgrade finished.

You should be moving hot air out of the case via the radiators not blowing it back in - the idea is to get the whole system as cool as possible.


I know this seems like what you want to do but it is better the other way, bringing the coolest air in through the radiator into the case. This is because you have the coolest air possible cooling the coils that go to cool your electronics. If you have a complete water cooled system this is especially important. Taking the hot air from inside the computer to cool the radiator really makes no sense.

I only cool my cpu with the radiator and then I rely on the other fans to exhaust the heat from inside my case. This gives me the coolest cpu temperature possible. The gpu's cool from their fans and the fans that both bring in air and exhaust the air through the case. Keeping the air moving through the case really helps.

I know my AMDs run hot. My computer room is getting very hot in what is only supposed to be Spring temps here. I try to use efficient cooling on the CPUs. Now here comes the "monkey wrench", as we say, I am running two different temperature monitoring programs they differ by 20C as to what the temperature is. I try to keep the temps below 80C as the computer self protects above that and shuts down.


Just for your information Bill.
A FX CPU for example shuts down at 71°C.

I did not know that as I have seen CPU temps over 90C on two of my computers when the computer room is way overheated. I take immediate action when I see that.

Confirmed, it is per GPU regardless of vendor.

Still 100 per CPU - no change. For single CPU hosts, at least.

That is what I am getting and my GPUs are the same on each of my computers.
So 300 tasks per computer for me.

Before: Zotac 9800GT, TDP 125 watts, purchase price (Jan 2009) GBP 77.47 before sales tax.
After: Gainward 'golden sample' GTX 750Ti, TDP 60 watts, purchase price GBP 99.75

Richard, what GFLOP rating does BOINC give for your 750Ti? I replaced a GT 440 with an EVGA "Super-clocked" 750Ti today (because my proprietary [(hp)] rig doesn't have any PCI-e power connectors). BOINC reported 311 GFLOP for the 440, which agrees with the figure on the Wiki NVIDIA GPU page, but that gives 1306 for the 750Ti while BOINC reports 2406.

Boinc reports 2082 GFLOP on my 750TI and that is not overclocked.

Just coming on here but having read all you have done so far I just wanted to be sure of what you have done, or are doing.
Disconnect the old HD and install the new one.
Then try a startup boot with the DVD in your drive.....you do not need any drivers for this to happen......there is no reason to try to install the new DVD drive to the XP HD.
Make it as simple as you can to start, old computer, new HD and DVD with the 8.1 disk installed in the DVD when you turn it on.

I am not certain about any problems you were having, but you are running an older version of BOINC. Just wondering if a later one would work better for you.

I can see on my systems that even though the GPU is not working 100% I can never seem to get that no matter how many WUs I run on them. I have dedicated cores on the CPU when running APs but when the APs are running, that is when my GPU shows a very wavy usage graph (and it is a very uniform up and down.)
10) Message boards : Number crunching : Overheating on laptops (Message 1503718)
Posted 13 Apr 2014 by Profile Bill GProject donor
I have given up crunching on my Dell laptop as even when I removed all the screws it was impossible to open the case to clean out dust. It gradually ran hotter and hotter and I gave up when it routinely reached 100 oC. The suggesting to stand the laptop on cofffee mugs is a good one, though I used two books to achieve the same effect with more stability.


I do not completely dismantle the laptop, I just remove the memory access and the HD access ports on the bottom of the laptop and blow it out from there with air from my compressor. This is where the dirt builds up as it is in the "flow path". You can (and should) of course also blow air in the intake vent on the bottom. Works wonders with the air flow.

And I do have the laptop mounted on a pad with a fan in it. It does overheat otherwise. (only crunch CPU as there is no GPU in the laptop.

I do not think you have enough memory in this computer. You should have at least 2G IMHO.

Posted 25 Mar 2014 by Profile Bill GProject donor
As long as the account is the same it should easily merge. Just remember that you will not be able to merge right away.....at least that is what I found. It takes a day or two before you will see the other units.

Posted 25 Mar 2014 by Profile Bill GProject donor
From my experience, you should be able to merge the two computers without problem. I did like 4 builds to test both MBs and OSs and just kept merging them into the now running computer. (my names did not always match by the way)

I know others will tell you differently but I have had great success with just keeping everything going. You will probably loose those WUs in progress as you will have to change some MB drivers I am sure. But the WUs that have not started will do just fine. IMHO......

Posted 22 Mar 2014 by Profile Bill GProject donor
I know you have said that both cards are running cool. But, it is possible that it is a position thing with air flow or cooling. I sometimes wonder if the sensors really are accurate in all cases. You might want to try an extra fan or open case with fan blowing right on the cards and see if that makes any difference. I know in one of my computers one GPU shows 60C and the other GPU shows 80C and that is with the fans running 90% which is the highest I can manually crank them up. (and there are extra case fans as well)

It is in Program/data/boinc and it s xml.

Sorry to jump in here but, if this is where he is looking it is the wrong place Richard.

Sorry but I do not feel comfortable deleting anything as I am not sure what I am doing. I could post the entire file but that seems like a lot of bandwidth.

I will try an email, I hope that is OK?

Posted 10 Mar 2014 by Profile Bill GProject donor
Remote Desktop will stop GPU processing. MS Remote Desktop video drivers are not compatible. You do have to go to a 3rd party remote access. (I have switched to TeamViewer as well and it does all, and then some, that I need)

The computer will work fine, doing CPU and GPU processing as long as you do not access it using Remote Desktop (personal experience).

Just a bit of history to start: this is the basic computer that we could not get to stop throwing GPU errors when I was running on Win 8.1. Well I put a new HD in and installed WIN 7 and basically had the same problems leaving me with no solution except it is probably some driver and the AMD CPU (remember I tried two different AMD CPUs and two different MBs).

Well I have found that with the current setup if I run a MB on the GPU it will error out with a -9 overflow. So I stopped accepting MBs and only accepted APs.

Now I can see that running APs on the CPU is just not efficient at all, they take close to 15 hours to complete while on the GPU they take 1-2 hours.

What I want to do is run the APs only on the GPU and MBs on the CPU. There must be some easy way to do that?

Current settings are no MBs but I will accept if nothing else is available which gives me a few every now and then.

This is the current computer in BOINC: http://setiathome.berkeley.edu/results.php?hostid=7226971
