January 8, 201412 yr I'm trying to track down some random, re-occuring parity sync errors. A 48 hour memtest revealed no errors at all, and when I run prime95 blend it immediately stops and says "out of memory". Is there a way to run prime95 from the USB boot drive similar to how we can run memtest without booting up the entire system?
February 19, 201412 yr I'm just going through some unraid server memory testing myself (using the embedded memtest), and coming across prime95 discussions in this forum, I was just contemplating to try that as well. I wasn't planning however to load it on unraid.... I will use one of the Linux distributions loaded on a usb3 flash drive, download and install Linux version from here: http://www.mersenne.org/freesoft/ and run it. Will probably have it done before the end of the week. I don't foresee any problem with this approach. You are perhaps thinking of an embedded version in unraid package?

Please let me know how it goes with Prime95 via USB boot. I haven't been able to get p95 to work on my server at all, it always crashes immediately.
February 20, 201412 yr An update. I happened to have an old drive lying around and was already preloaded with Linux Mint 64 bit . I had spare power and sata connections on my server, and so I just plugged this drive in, used it as a boot drive, downloaded the 64 bit version of mprime, and launched it. It will be asking how you want to run it - you don't need to create the account on their web site, and just run the blended test. It might be compiled to be self sufficient, with no calls to any dynamic libraries - for me it just worked, and it is running on the same machine I'm typing this message... I wonder if you could take the 32 bit version save it on unraid thumbdrive, and run it from within unraid. It may or not work.. Otherwise you should be able to get it running fairly easy getting a decent (more complete)/recent Linux distribution on a usb flash/or spare hdd and run it. You should read the stress.txt for some expectations. Good luck.
February 20, 201412 yr Author I just logged into my unRAID box through SSH and downloaded p95. But, when I run the blend test it crashed immediately. No clue why.
February 21, 201412 yr That intrigued me... but everything is possible... Check the web site and text files joining the program, perhaps there are some clues. The stress.txt warns about the different tests & errors scenarios. I did that test finally myself - while the machine was still running mprime from the hard drive (in Linux Mint), I plugged in unraid thumb-drive and downloaded on it the 32bit version. Unpacked it and then I rebooted again, this time loading unraid minimalistic OS. Tested this on my server equipped with an old Supermicro H8SMi-2, and 8GB of ECC RAM, all correction/scrubbing options turned on, etc. Mprime run without complaints, asked the initial questions about scope of the test, and then it just ran. I didn't let it run more than 10 min... ... as I had to go back to my wrestling with a LSI SAS 9240-8i, which I cannot set it up properly, crossflash it with a lower end model, and then be able to use it w/o errors in unraid. I get all kinds of errors, and I have no spare motherboards to use to eliminate the errors I come across in the firmware upgrade process.
