1) Message boards : Number crunching : exit code -1073741502 (0xc0000142) (Message 10068) Posted 27 Feb 2005 by old_user52381 Post: I get that error message now. My Boinc is claiming no schedulers are responding. I get the error message when I reach the end of phase two, with network connection disabled (in Boinc). I'm going to try it now with the connection enabled to see if it helps.

Also, that could be a good idea when using it on your lap, so as to avoid <a href="http://channels.lockergnome.com/hardware/archives/20050208_overheated_chips_get_doused_by_readers_suggestions_for_cooling_systems.phtml">lap-burn</a>. :-)
4) Questions and Answers : Windows : Pointless continuing from backup? (Message 9687) Posted 21 Feb 2005 by old_user52381 Post: > ... the server is accepting the trickles, and should accept the results in due course. So they get the benefits of your work and you get the credit. Is there a project admin who can confirm this? I know I get the credit, I just want to know I'm not wasting time on results which automatically will be discarded because of the -5 status.
5) Questions and Answers : Windows : Pointless continuing from backup? (Message 9682) Posted 21 Feb 2005 by old_user52381 Post: During phase one I got a -5 error. I had created a backup though, so I just continued from the backup. However, now (halfway through phase two) I've noticed that the results I'm working on http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=533734 is still claiming a -5 error. Is it pointless to go back to a backup after a -5 error, and if so, what's tha point of backing up?

I believe you can, at least for CP.net. Am I wrong? Also, for those using MSI CoreCenter to check their CPU temperature I would like to recommend upgrading to the latest version from MSI's website. The new version (1.7.3) reports temperatures about 5 C lower than my previous version (1.6.8 I think). So, I presume, the old version was reporting too high figures.

In fastest run currently at 4.14 > sec/TS - is the "cool & quiet"-feature a 'slow downer'? CPU-Frequency is > only at 1000 MHz and CPU Voltage at 1.0750 V. Yes, that's a known problem with Cool n Quiet which I've read about somewhere. (The fact that it stays at 1000 MHz even when under full load.) Your processor should probably be doing 2,2 GHz or something like that if it were running at full steam.

(Message 9110) Posted 11 Feb 2005 by old_user52381 Post: Well, apparently, the Newcastle AMDs and the MSI K8T Neo are notorious for giving strange temperature readings. I've now managed to activate Cool n Quiet anyway, using the AMD driver on <a href="http://www.aceshardware.com/read.jsp?id=60000301">this</a> page. I didn't realize before, but it doesn't have any effect when running at full speed. :-)

11) Message boards : Number crunching : Bad for CPU to run 100%, 24/7 @ 62 degrees? (Message 9033) Posted 9 Feb 2005 by old_user52381 Post: Well, I don't think 62 degrees is the end of the world. I found <a href="http://www.amd.com/us-en/assets/content_type/DownloadableAssets/FAQ_Rev05_ENG.pdf">this PDF</a> at AMD.com which says that a normal reading from the CPU should be 60-65 degrees C or lower. EDIT: Also, there is <a href="http://www.amd.com/us-en/assets/content_type/DownloadableAssets/K8_Electrical_Spec_Rev_ENG.pdf">this</a> document listing the range of case temperatures in which the CPUs can work. (I believe.)

(Message 9025) Posted 9 Feb 2005 by old_user52381 Post: @grahamd: Sorry, I should have said, I meant degrees C. @geophi: I've got a 3200+ which, when running at the default speed of 2200 MHz with the casing closed, reaches 62 deg C. Thanks for the tip about motherboards, I'll see if I can dig anything out there. I was contemplating on getting a twelve centimeter fan to use as an exhaust, as suggested on the page you gave me.
13) Message boards : Number crunching : Bad for CPU to run 100%, 24/7 @ 62 degrees? (Message 9006) Posted 9 Feb 2005 by old_user52381 Post: Well, my subject line pretty much sums up my question. I spoke to a friend a few minutes ago and told him about Climate<i>Prediction</i>.net. He (who is far from computer-illiterate - OTC) told me to stop doing this, because running constantly at 60 degrees would make my CPU (an AMD64) short-lived. If that is the case (which I doubt) then it is a very well kept secret here at CP.net. My forum searches for CPU damage (and other things) didn't give me anything on this subject. Anyone know if his claim is true or not?
14) Message boards : Number crunching : What's your lowest s/TS? (Message 9001) Posted 9 Feb 2005 by old_user52381 Post: So, to sum up, the lowest value so far in this thread is an equivalent of 1.20 s/TS when running two models simultaneously on a 3.4 GHz HT Intel. I just realized there isn't such a thing as a 4.0 Intel (apart from OC'd ones of course). Anyone have any exact numbers for the 3.6 and the 3.8?

I sortof guessed something like that might be the case.
19) Message boards : Number crunching : What's your lowest s/TS? (Message 8917) Posted 8 Feb 2005 by old_user52381 Post: Done a memory benchmark using Everest now: 3193 MB/s, 1080 MB/s and 62.0 ns. I've found that using the 'Dynamic Overclocking' function of my motherboard (MSI K8T Neo-FSR), having it set to 5 % (which at full usage makes 2200 MHz -> 2310 MHz) i can reduce my s/TS somewhat, from about 2.27 to 2.20 :-) The memory data above were with the 5 % dynamic overclocking switched on. One thing I'm seriously wondering about: How can some people using computers substantially slower than mine get higher RAC than me - I've had mine running basically 100 % for 36 h now (since I joined).
