Google translate for me too. Thanks for the information Raistmer.

I was reading about it in today's newspaper and thought of sharing the link about FAST.

Is there any specific brand of pci-e riser that is good to use, or can any unbranded model ok for use? On several forums I have read how the bad soldering on these risers have blown the motherboards or the GPUs. Even the Thermaltake ones have received bad reviews on Amazon.

Also, is there any limitation on how long these can be? I came across this site indicating various lengths.

Many sites gave good review for 3M Riser cables from Digikey, but the costs are exorbitant compared to the others for both 25cm and 50 cm length.

I have been in search of good and bright spotlight since the last one I had went kaput. My searches led me to a page on Vector Sportspot VEC 192. This design is perfect for me to use on the farm at night, and the additional LED on the handle would be really useful. The bad part is, that nowhere can I find one to purchase. The closest I could find was the Cyclops C18MIL Thor X Colossus, which is a humongous piece of hardware.

I have tested a few others that boast 25 and 40 million candle power but are much dimmer than the one I had which was only rated 15 million. Would anyone have information on where I can get the VEC192? Another spotlight mentioned on the same page Vector SLH100P also seems not available.

Any help would be appreciated.

This is good information, thanks to everyone. I am planning to get a couple of GTX 970s for my new rig. Would there be any difference in using the mini ITX version compared to the regular ones?

7) Message boards : Number crunching : AVG creating havoc with seti rig (Message 1748672)

My main PC runs Bitdefender Internet Security, which I have been using since 2009 without any issues. However, since my seti rigs are 24/7 crunchers and not used for anything else, I didn't see the need for such a high end (?) antivirus for it.

I am yet to test Nanopro. In the meanwhile, I have been checking the rig with the issue and have come to the conclusion that AVG web tuneup is the culprit behind all my troubles. It creates a shadow copy of all the other files on the PC thereby sucking up the available disk space. Quick google search has corroborated this. I remember not selecting this feature of AVG during install, but I guess a latest update might have installed it. The solution is to uninstall the AVG web tuneup. Then manually delete everything under AppData\Local\Packages\windows_ie_ac_001.

I gained 33GB on my second rig by doing this and things are now back to normal. AVG seems to be running ok too. I wonder why AVG isn't doing anything about this, given the number of complaints about it on their forum.

From both your replies, I will now have to exclude Avast and Comodo. I have looked up PCMatic and the lifetime license for $150 looks tempting, but they do have a free version which I will test on one of my rigs. I have also checked ClamAV, but since it doesnt have a real time scanner, I will exclude it as well. I also came across NanoPro, might give it a try in a spare PC.

Edit: I did a quick search about PCMatic and came up with loads of negative reviews about it. This Amazon review page has given a pretty clear picture of what this software is. So this too is off my list.

Recently I have noticed my crunching rigs running out of space and giving me the 'not enough memory' messages. Upon inspection, I found that AVG antivirus has been filling up my hard drives. The empty space that I gained by deleting temp files would again be filled up by AVG. In the end I decided to uninstall it on one rig, which unfortunately, caused the entire WU cache to error out and the project had to be reinitialized.

Now it is back to crunching again, however, 503 WUs were trashed. This rig doesn't have any antivirus on it now, and I am not very keen to use AVG again, even though my AVG license is still valid for another year.. My question is, should I really install another antivirus or just let it be? If yes, are they any good business edition ones? Free ones would be better as I would like to try them out first. Is Avast recommended?

I have been following this thread since long. Never built a super cruncher, however, here are my rigs.







I am still in the process of building my 3rd rig. So far, it is just a CPU cruncher. Got the motherboard cheap on ebay so I could reuse my old CPU. GPUs will need to wait till I have the budget. Currently uses an old Radeon X1300 since there is no onboard video.



The second card on my main rig GTX 285 gave out a couple of months back. These were the very first GPU that I purchased way back in 2009. Rigs 1, 2 & 3 are controlled through this via VNC.

Hey Vipin, quick off topic question, what prompted you to switch from Zorin OS to Mint? You mentioned that you thought it was easy to handle, are there big differences between them? I tried Redhat in the late 90's and again in the mid 2000's, but it never really clicked with me. I saw Zorin (I think it was version 6 a few years back and donated so I could get the full version. The big thing for me was that it has the traditional Win XP Classic (95?) interface available, which I know and to this day am still most comfortable using, and installed it on a backup machine to play with. Life got busy, and I never really used it much, tried running BOINC on it, seemed to work fine, but then it fell off the plate. Anything you can say about it, and Mint now as well? Thanks!


Even though I have been using Linux for quite some time now, I still consider myself a rookie. After having tried both Zorin and Mint, I feel that the interface of the latter, especially the Mate version is more user friendly. The menu is almost identical to what you would find on a windows machine and so are most of the applications and settings, or the control panel like setup so to speak. Although identical in their core operations, I felt that Zorin required more user input compared to Mint and thats what made me settle for the Mint Mate. I am yet to try the Cinnamon flavor but from the screen shots and reviews, it is kinda similar.

Previously I have tried Redhat and Fedora, but both of these I feel are for Linux Gurus. Also, installation process for Redhat is way to complex for me.

I have been trying out various versions of Linux recently and found Linux Mint to be quite easy to handle. I have a laptop which is running BOINC on Zorin OS. I now want to transfer this to a Linux Mint installation and not sure how to proceed. With windows its just a matter of copying the two BOINC folders in program files and program data, is there any such process available in Linux? I tried searching the forum but it came up blank.

Post:
Thanks for the links Troy. I had been pondering over the idea of installing the AC fans and got my hands on two spare fans that were purchased for chiller DDC panels, however, lack of time and in view of most of the comments here, I decided against it. Instead I found Sunon PMD1212PTB1-A.(2).F.GN on ebay for around $12 and ordered 4 of them. Test result was satisfactory and its a bit louder than I want. The next step was to purchase the NZXT Sentry Mesh to regulate the speed. At around 60% setting the fans are inaudible, and I can ramp them up as needed. Bgear 120mm fan filters were added as a dust control measure.

For my GPU fans, I found replacement parts on aliexpress and ordered them for both the GTX 660 and GTX 650ti. The one for 650ti arrived last week and it was a quick replacement. The other should be in my hands next week.

Apologies for kinda hijacking this thread, but are there any new optimized apps in the pipeline? An installer with newer AP7 codes would be helpful too.

For low end cards, 1x, 4x or 8x might be ok

I've used a 1x before with a gtx 750, but when I tried with higher end card it wouldn't work.

I tired a 16x as well with high end card, but it too wouldn't work as well.

Don't know if it has something to do with requirements of the higher end cards.

You might get a different result. I ended up opting for a new MoBo

I just went for the higher end boards, I've got 4 so far, 3 have cases, the 4th doesn't yet, but it will, an X9 for 4 and 5, 1 each of course.


Again, thanks for the tips.

Only my main rig is in a case, the rest are all open bare bone system, subjected to direct flow from the AC outlet. Helps keep them cool in this desert environment.

Thanks for the info. I was worried that these flimsy looking ones might cause trouble with the mobo/GPU.

I won't go with any PCIe 1x riser with high end cards


I have read on many sites that 1x, 4x or 8x work as good as 16x slots when it comes to computing, so I am a bit confused here.

What sort of GPU will you be using with the riser? Some cards will not work with certain risers, other will. So knowing what the GPU cards is first helps


I wasn't aware of that. I am planning to get a couple of R9 290/X. I found 3M 8KC3-0726-0500 cables but they are extremely pricey compared to what Amazon has.

Can anyone recommend a good quality pci-e riser card. I have checked on Amazon and most of them have negative comments. So not sure which ones to buy without the fear of wrecking the mobo and GPU.

Vipin,

Did you check eBay?

http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2053587.m570.l1313.TR0.TRC0.H0.Xfans+for+Asus+GTX+660.TRS0&_nkw=fans+for+Asus+GTX+660&_sacat=0


Thats neat, thanks a lot. I never used ebay before but must give it a try now.
