It seems that I will not be able to fix the cooling for my GTX580 this year, so I unreserve the current range for N=37. I had finished 61P to 72057594037927935:

[CODE]no factor for k*2^37+1 in k range: 61P to 70P (93-bit factors) [mmff 0.26 mfaktc_barrett96_F32_63gs]
no factor for k*2^37+1 in k range: 70000000000000000 to 72057594037927935 (93-bit factors) [mmff 0.26 mfaktc_barrett96_F32_63gs][/CODE]

The range from 72057594037927935 to 80P is approximately half-way. [URL="https://www.dropbox.com/s/i5gznxko314fm64/F37move.zip"]Here[/URL] are the worktodo, checkpoint and ini-files if someone wants to finish that small range (should take about 15 days on GTX580, if I remember correctly).

The range from 80P to 100P could just be released. Sorry for the extra trouble Luigi, and I hope I can continue with the GPU asap - at least when it is still winter here (although the current +2C does not really count as winter in my books..).

No problems. I am having thermal issues on my GTX580 as well, and my range at n=39 is progressing very slowly.

Is there anyone around willing to complete the range? Cyrix has already taken n=37 and k from 100P to 110P, and I don't like "holes" in the ranges... but as I said before, I just can't take it myself now.

Luigi,
I'll finish the range. My 2^34 reserved range has less than a week to go. I thought I had finished it, but found a hole when assembling the results.
One of my other ranges has about 10 days -> 2 weeks to go.

When dealing with overheating GPUs, a few things to try from my experience) is:
#1, take the shroud off the card and blow out the dust with "canned air" or a hair dryer. Sometimes the heat sink and fan get dust clogged reducing cooling efficiency. You must remove the card from the machine to do this which is sometimes difficult.
#2 run your machine with the cover off ( if possible ) to see if that helps. Maybe the exhaust fans are not discharging the heat from inside your case.
Be careful if your set-up depends on a cover being in place to assist the cooling, though.
#3 install a utility to increase the fan speed manually.
#4 Have you tried rebooting your machine? I have noticed after long runs that the fan speeds sometimes "creep" up or down for no reason.
Just my 2 cents, YMMV.

Thank you tServo for taking the range.

I have also noticed that dust in the heat sinks can have a huge impact on the temperatures. However, this time my overheating problems were caused by an apparently broken water bump (in my Arctic Cooling Accelero Hybrid). I wanted an easy quiet solution for transferring heat from the GTX580 and bought the Accelero Hybrid. It was relatively nice in many regards: quiet when using quiet 120mm fans attached on both sides, it was easy to mount to a place where air would come essentially directly from outside the casis to the radiator and then blow out from the casis, and it was relatively easy to keep clean of dust. I was expecting the water bump to last much longer, so I am not that happy with the Accelero Hybrid anymore...

Thanks Marvin :smile:

My case always runs without cover. I guess the problem is in the 2 GPUs mounted side by side that stop air circulation, anyway I will blow the dust out soon.

Since there are 2 boards side by side and you run with the case open, another thing to try, if possible, that would be easy is to direct a small fan, one that's about 10 inches or 25 cm diameter, directly at the point where the fan intake is. Some cases actually have fans like this built into them. I have several fans like this pointed at some machines that I also run with the cases open. The ones I use run on A/C and are sold as "table" fans or "personal" desktop fans. It could be difficult to find fans in winter, tho.

It is a good idea. I planned to buy a new case with multiple air flow management, but then my home heating system broke and I devolved (ten times) the amount of money needed for the case to it. :sad:

Rajula, I finally got around to starting to finish this range but when I unzipped the 3 files, It seems like they are not readable by my windows machine.
The worktodo file has 3 entries but were smushed all on 1 line.
I separated them and them started mmff, but it didn't recognize the .ckp
file that was there. It said 12 days to finish ( i have a gtx 580 classified ultra ).
I wonder if this is a unix/windows file compatibility issue? Is it worth my getting the .ckp file alone or should I just do the range from the beginning ( it isn't that big of a deal ) ?
BTW, Happy New Year, everyone!
