March 14, 201610 yr So a couple of days ago i received my RAM upgrade, 64GB of joy I installed it an went on doing other stuff. yesterday when i finally got the time to play with my unRAID server i saw it behaving weird, and over the last 24+ hours it has been reformatted, had new usb drive installed and so on and still - very unstable and weird behavior. Today i realized that on the "dashboard" in the GUI it says MAX 64GB Ram and it got 65,xxx installed - WT* - it got 8*8GB ram. So uncliped 2*8GB ram and ... it seems to run fine now. So what's going on? 65GB ram on 8*8GB ram sticks? And is it why unRAID is spazzing out? Server is HP xw8600 supports 8*8GB ram or 16*8GB ram with an riser.
March 14, 201610 yr Community Expert Because '65,xxx' is exactly 64K defined as a decimal number --- which is 64 x 1024 = 65536 (K is defined as 1024 --- 2^10) I think you probably need to run memtst which you can find as an option during the unRAID boot process. Since you have 64 of RAM, you should run it for 24 hours minimum. Did you get RAM recommended by the MB manufacturer? Are all of the memory chips from the same manufacturer? I have heard that as you install more and more memory strips on a MB, problems often surface with timing and other memory related issues. You may have been bitten by one of them.

They are all the same, 8GB 2Rx4 PC2-5300F-555-11-D0 ECC ram, from HP these ram are the original and recommended ram for this HP workstation. It dosen't matter witch one i pull out, just as long as the installed memory is less than the 65xxx mark, right now it's been stabel with 6*8GB + 2*2GB ( 2GB 2Rx4 PC2-5300F-555-11-D0 ) I did run the Memtest that followed with unRAID the first day, with no errors.
March 14, 201610 yr Author Units. Conversions. Learn them. wow rly? So my problem is that i did't calculate it with the kibibyte system? Well ok, i must tell my server that it's the problem, sure it will fix it right away!
March 14, 201610 yr Author SO. Back to "topic". In the Dynamix System Info it shows: 66560 MB installed, and 128GB as max (with the riser card that i don't have installed) Not Specified = 8192 MB, 667 MHz Not Specified = 8192 MB, 667 MHz Not Specified = 8192 MB, 667 MHz Not Specified = 8192 MB, 667 MHz Not Specified = 8192 MB, 667 MHz Not Specified = 8192 MB, 667 MHz Not Specified = 8192 MB, 667 MHz Not Specified = 8192 MB, 667 MHz Not Specified = 1024 kB, Unknown on the dashboard it says 65,536 MB (max. 64 GB). Any clue on why that is? Also, as i now running full 8*8GB Docker and VMs and more is not working, but replacing anyone of the 8 men sticks with a <8GB ram fixes this.

Well ok, i must tell my server that it's the problem, sure it will fix it right away! Ya,RLY! Your problem has nothing to do with the fact that 64GB = 65536 MB. Your problem is entirely something other than the basic scientific computing facts.
March 14, 201610 yr I'm not sure what the original problem is. Unless you post some diagnostics nobody can help.
March 14, 201610 yr Author I'm not sure what the original problem is. Unless you post some diagnostics nobody can help. The symptoms aren't always the same, but sure i can post it, just from the diagnostics under tools right?

Your problem is entirely something other than the basic scientific computing facts. So what about the 66560 MB installed ram then?
March 14, 201610 yr Author I agree with BRiT on that.... On the 64GB = 65536 MB. part? I agree that 65536MB is refferd to 64GB got confused with the google conversion - see attached photo. But what about the Dynamix System Info that shows 66560 MB ram is installed? And what about the Not Specified = 1024 kB, Unknown part in Memory? Pointing out the obvious dosen't help, 64GB is 64GB, but some parts of the system is showing more than 64GB, it shows 66.56GB. So, what going on? I'm new at unRAID so again - the diagnostics is the diagnostics under tools in the GUI then?
March 14, 201610 yr Community Expert What happens with these numbers is you ask for the size, and it is given in some units that may be 1024 or may be 1000, and then to make the number have fewer digits, you divide it by 1024 or 1000 and so you can wind up with a lot of different answers that all mean the same thing. Don't know what to suggest about your actual RAM hardware issue other than what Frank1940 has already said. Is your BIOS set to the default settings?

Don't know what to suggest about your actual RAM hardware issue other than what Frank1940 has already said. Is your BIOS set to the default settings? BIOS is set to default, and when i boot after plugging in the ram's it recognize all of them, tried a windows install and it also works fine there, for some reason unRAID dosen't like it though. re-inserted the 8*8GB ram system boots all is fine, boots in to unRAID - and this time everything looks good. So did the diagnostics and stopped the array to shut down aaaand it's spazzing, can't shutdown, can't SSH in to it, can't do anything, did a diagnostics and it downloaded, tried again and it just hangs in the download. Don't know if the diagnostics attached will do any help, but here they are. tower-diagnostics-20160315-0044-ARRAY-OFF.zip tower-diagnostics-20160315-0043-ARRAY-ON.zip
March 15, 201610 yr Something is up with you flash drive. Run chkdsk on it in a windows PC or try another.
March 15, 201610 yr Author Something is up with you flash drive. Run chkdsk on it in a windows PC or try another. Just did it, it came back saying: Windows has checked the file system and found no problems. It's a completely new flashdisk, but again unRAID is doing some weird stuff when i run *8*8GB - see attachment (uptime 5mins).
March 15, 201610 yr Author What did you format it as? FAT? FAT32? Try swapping FAT32. And it's working fine on less ram. Swapping?
March 15, 201610 yr Try FAT instead? Can you relax the ram timings in the BIOS? Have you run the 24hour memtest yet? When you remove some of the ram and it "works" are you always removing the same sticks?
March 15, 201610 yr Author Try FAT instead? - can try it tomorrow (it's 1.51 in the morning here ) Can you relax the ram timings in the BIOS? - i'll look in to it. Have you run the 24hour memtest yet? - did it the first day and was the first on my to do. When you remove some of the ram and it "works" are you always removing the same sticks? - nope, tried almost every one of them.
September 28, 20214 yr Bumped, as this hasn't been resolved yet, and I am currently running into this issue as well. Any further development?
