21) Message boards : Number crunching : Help with Case Fans and GPU Fans (Message 1692583)
Posted 17 Jun 2015 by Profile Vipin Palazhi
Quite a few 120x120x25 230vAC fans with <100m3/h
First one I came across - Sunon SP101AT-1122HSL.GN flow of ~136m3/h

As for you GPU fans - what diameter and depth can you get away with?


Thanks, however, 1122HSL.GN is rated at 78cfm. As for the GPU fans, I haven't measured the dimensions. The current thickness is two slot wide, and hence the same is required, else it will touch the PSU. Diameter wise, it should lie within the edges of the GPU itself.

Would anyone have information about 120x120x25 mm case fans running on 240V AC, with atleast 100cfm airflow? The best I found at 25mm thickness was rated at 80cfm. I found many at 38mm thickness, which due to space restriction in my case, cannot be used. I plan to replace my 12V DC fans which are only 35cfm. DC fans at higher cfm are too loud.

Also, due to my own dumbness, I managed to break the fan fins on my Asus GTX 660, and one of the fans on my Gigabyte GTX 650Ti is jammed. Any suggestions for replacement fans which will stay within two slot widths?

It will be interesting to see how low my RAC will go before we start getting new work again?

I am a hardcore seti cruncher, but I had joined Einstein to coverup outages. My RAC in Eintein used to be around 1000-2000, but now it has shot up to 90000. Hope Seti gets back online soon.

Since the upload servers are out, my rigs are all out of work. Falling back to my spare project for now. Hope all is back to normal soon.

After lots of retries, the rigs have not reported the work, however, as others are experiencing, there are no tasks available. Restarted my backup project for now.

My rigs have not been able to report the competed WUs since almost 12 hours now.

Something wrong I guess.

Unfortunately with all the power available via GPUs, cracking longer, full sentence passwords are a fairly trivial affair: http://arstechnica.com/security/2013/08/thereisnofatebutwhatwemake-turbo-charged-cracking-comes-to-long-passwords/, http://arstechnica.com/security/2013/03/how-i-became-a-password-cracker/, and http://arstechnica.com/security/2013/05/how-crackers-make-minced-meat-out-of-your-passwords/ show details on how just about anyone can do it these days.

Increasingly password vaulting software such as KeePass that will randomly generate difficult to crack passwords will also save them for you. The downside is that if you're using complete hard drive encryption and require a password at boot time (like my company does), having a software-based password vaulting software won't help much.


All I can suggest is Password Generator and Password Meter.

I have been running the NativeBOINC app on my not so powerful android phone for a few months now. The app seems to be doing a good job in crunching, so far.

Although not directly related to crunching, I am getting the "Untrusted Connection" message while trying to open seti@home account using Firefox. Says the connection is unsecure and the certificate isn't valid. All seemed ok till yesterday, however, there seems no issue with IE. Anyone else having this issue or is it just me?

Edit: Please disregard, it was some issues with the proxy settings.

33) Message boards : Number crunching : ATI Radeon R9 290X (Message 1466270)
Posted 19 Jan 2014 by Profile Vipin Palazhi
Prices of 290 and 290X are well over recommended by AMD. People mining coins buys them like hot cakes. AMD advantage is gone. I can't see price wars (that I was hoping) in near future...


I did note the higher price tag on these cards compared to what AMD used to release before. However, I have never been able to understand the bitcoin stuff. Nevertheless, I really want a couple of ATI cards to cruch seti and the 290X seems to be the best one currently available, unless someone can point out another one.

Thanks for the info Mike. I shall try to get a couple of the 290X then.

Posted 18 Jan 2014 by Profile Vipin Palazhi
Now that the new ATI Radeon R9 290X is out in the market, I am hoping there will be a good competition for nVidia's 780Ti. Here is a good review from Anandtech.

I have been using nVidia till now. Recently, one of my older GPUs, a GTX 285 went bad. I need to replace it and was thinking of getting something from ATI for a change. Does anyone out there have this card crunching Seti? Any suggestions regarding the performance and value for money?

Edit: The Windforce model from Gigabyte is listed for $700 by Newegg.

36) Message boards : Number crunching : Upgrade Windows XP (Message 1462068)
Posted 9 Jan 2014 by Profile Vipin Palazhi
Even though MS will stop the support for XP from April, you can continue to use the OS. The only thing missing will be the regular updates, and Boinc doesnt need them to function. Just install a good antivirus (even the free version of AVG is good enough) and the rig will be good for as long as you want to operate it. However, if you have planned to upgrade, Win 7 Pro is a good choice. Ubuntu is free ofcourse and does function well, however, since I am not that good with Linux, I will leave it for others to comment upon.

With windows XP, the Administrator account is created by default and is shown during startup, as you were seeing it. The moment you create a new user, the Admin account will get hidden and you will only see the user account. You can switch off the graphic logon from Control Panel > Users Accounts



Deselect both the options.



You will be presented with something like this

38) Message boards : Number crunching : Quick question about the GPU count (Message 1459979)
Posted 2 Jan 2014 by Profile Vipin Palazhi
4 x 690 cards, 8 GPUs

[Edit:] well looking closer, that particular machine has 2 x 590s and 2x690s, but the counts stand at least.


Pardon me for the ignorance but how do you "look closer" to find the different GPUs installed?
