SFF Unraid - Separating XBMC from server

yes, Prime95 is KING


and here's the Qualify Vendor List (QVL) for your motherboard

http://downloads.zotac.com/mediadrivers/mb/cpu/a127.txt

they tested these two.
Kingston KVR667D2N5/2G
Kingston KVR800D2N6/2G http://goo.gl/Xz19x

but that doesnt mean other models wont work,
they cant test all makes and stuff,,,,
and users who bought those i linked to havent reported issues...

How ever, as everything can break,
i say why not just RMA them,
and get the Kingston KVR800D2N6/2G http://goo.gl/Xz19x
then we'd know 4sure

Here's some captures of the RAM info, if someone would like to take a stab...
Sorry I couldn't screenshot. Was running MiniXP from a flash drive.

timing is ok

I don't think that the preclear is cpu intensive at all. If anything it is going to stress your SATA controller/chipset the most. And if you recall the unraid hardware compatability wiki said to stay away from the nvidia chipset you have. One of the best stress tests you can do for an unraid machine is to preclear multiple drives at the same time - the more the better. You already tried this and I'd say that it did it's job in pointing out that you have an issue.

FWIW, I had an issue similar to yours the last time I built a server. The drives would preclear just fine but I would get random lockups of the server. I ran memtest for three days and got no errors but I swapped the RAM to another machine (my HTPC) and I got a blue screen on it within a day. So bad RAM may not always show errors in memtest. At this point I think your best bet is to swap out the RAM for another set regardless of whether or not it passes memtest. If you can swap it with another set that is already working in a machine you already have then that is ideal. If the RAM does not correct it then try the PSU (again swapping it with a known good one from another machine if possible), then the MB and the last thing I'd change is the CPU.

i agree,i say why not just RMA them,

Update.

Got a brand new board from Newegg. I set it up as minimally as possible. Started pre-clearing a drive. Within 1 minute, complete lockup. See photos below.

Now leaning toward RAM. Eskro, I will pick up a stick of the KVR800D2N6/2G. I will also will order a 45w AMD Sempron 130 because I think lower power will be better for me anyway (OR just to have around ).

Thanks for all your help guys.

RAM it is. keep us up 2 date

FYI, some system BIOS's AHCI/sata mode stuff is in the raid submenu.

The system board I have will not enable AHCI/SATA on the e-sata ports until you till on raid support, but you never define any drives in the bios.

Wierd, I know..

That's my case ! i got it several months ago, similar configuration, using it as a Server NAS - Seedbox - XBMC.

This is my configuration for the work:
- LianLi Q25
- Asus at3iont-i Deluxe
- 4Gb Corsair ddr3
- Dell (LSI) Perc5/i + 512mb ECC ddr2
- 4x 2TB Samsung HD204UI (raid5)
- 1x SSD Kingston s100 8gb (boot)
- PS3 Bluetooth Remote
- Hauppauge WINTV-USB
- Ubuntu Server 11.10 + XBMC
- Additional software: tvheadend - pyload - deluge - webmin

my is a fanless solution on the motherboard, an Atom 1.6ghz dualcore overlcocked @2.1ghz, system is on a SSD drive by Kingston, 8gb is enough for Server s.o. and it's directly connected to the sata2 port on the mobo.. the 2tb x4 Samsung hdd are connected to a real raid card that supports raid5 configuration and has a real intel dedicated processor and 512mb of ECC ram + a backup battery for powerloss errors on the array.. so all the XOR operation on the hard drives have not workload on the Atom even in high traffic data movement; the partition is a XFS filesystem on a GPT partition table.

i have no internal PSU (all the system runs on 1 90w notebook power brick!) so i got a nice ventilation using 3 Noiseblocker PRO fans, 140mm front in + 2 120mm bottom and top.. on heavy load temp are between 37-39° C

the LianLi has 5 hotswap bay and my raid card support hotswap and hotspare on the array, so if any of the hard drives fails it can be replaced on the fly without rebuilding the array (if a hotspare is present) or rebuilding in hotswap without let the machine going down/off.

Interesting setup. So much more room without the PSU in the way! Nice job on the cable management. I hope to get there some day. Hopefully this week
