SM X7SPA-HF - Dead on arrival?

After reading loads of stuff on this forum I finally decided to go for it and started building my own unraid server.

I wanted a clean start, so I ordered all new stuff, this is the setup:

 

Unfortunately I can't seem to be able get it alive. What happens is after I power on a repetitive long beep is heard.

Things I tried so far:

  • booting without the hard disks attached to mobo and psu
  • tested memory in a laptop, worked fine there
  • tested with other memory
  • tested with other psu
  • cleared cmos by removing the battery and disconnecting the mobo from the psu for a couple of minutes

 

The BIOS manual says a repetitive long beep corresponds to the following error: no memory detected (yes I've checked several times if the memory was in place, it is, believe me!).

 

I'm running out of ideas and starting to think I'm just unlucky to receive a motherboard which is just... dead on arrival :(

Thanks for the reply,

 

I managed to borrow 2GB Hynix P/N HYMP125S64CP8-S6, but still the same result.

This memory isn't on the SM memory list but this one is: HYMP125S64CP8-Y5.

 

I presume the last 2 chars differencing isn't such a big deal... or is it...

It is very much so.

S6 - 800MHz

Y5 - 667MHz

 

this motherboard only works with 677MHz memories.

Supermicro boards are notoriously picky about RAM.  I strongly suggest you try to find memory that others of us have used successfully with this board, or that you have read reviews about others having success at places like Newegg.  There are specific things to watch for, such as voltage, speed, number of chips, etc, that are very tricky to judge between manufacturers.  Supermicro's memory support matrix is very insufficient because it leaves out a lot of legitimate memory.  To date, it seems most of us have the best luck with Kingston sticks.

I ordered one of the memories which is on the SM memory support matrix. Actually, there are only 2 memories on it:

Hynix HYMP125S64CP8-Y5 Hynix HY5PS1G831C FP-Y5 2 RoHS Low Profile

Micron MT16HTF25664HY-667G1 Micron 9AG27 D9JWB 2 RoHS Low Profile

 

 

It's a shame they don't put more on their list...

And the story continues...

 

I especially ordered this module  HYMP125S64CP8-Y5 because it was on the SM list. Unfortunately they send me this module:  HYMP125S64CP8-S6.

On the label it says 667Mhz speed, but after looking it up, it appears to be 800Mhz... which DOESN'T WORK.

 

After contacting the shop, they told me the Y5 module is out of stock and out of production. But I've send you much faster memory for the same price he said (aargh).

 

The shop now agreed to take the memory back and I saw they have Kingston KVR667D2S5/2G modules in stock, so I'll replace it with that.

After looking arround on this forum, I found out KVR667D2S5/2G works... lets hope it does and that it will solve this crappy problem.

You are never going to believe what just happened... it works!!!!

 

After a final attempt of getting it to work, I removed all connectors once more, removed the CMOS battery and tried booting it once again with only the power connector attached... it suddenly came alive (woohoo)...

 

Tested the system some more... and so i found out the front usb connector of the case was causing all the trouble. When I plug it in... the system refuses to boot and starts beeping a memory not found error. There are 2 usb connectors located on the board, I was always using the same connector, I now switched it to the one next to it and it works.

 

So now I can finally start testing unraid on my brand new system 2 months after I ordered all my stuff.

 

 

Fieuw.... :)

This morning, I received 2x KVR667D2S5/2G modules... I was very hopefull, plugged them in and.... IT STILL DOESN'T WORK

 

Can anyone please help me? I'm losing it... GRRRRRRR

 

 

....this is very frustrating, I agree.

That memory has been reported to work, so lets assume its not the memory itself and not the board,

I'd try the following:

 

- run the clear CMOS procedure to make sure no traces are left of older attempts

(don't know if this is really feasible but at least I'd try to revert to manufacturing state as close as possible)

- you did buy two modules...are they paired by Kingston as a kit?

  If not, try only one at a time and make sure you fit the single module into the right slot

- make sure you fit them tight and correctly... the DIMM sockets are not made for clumbsy fingers ;-)
