Hi, I usually play with my beautiful SR-2, Yesterday I rendered my last work. Today I turn it on, everything switch on but the friendly-three-beeps didn't play. I reset and it won't boot anymore, with the blue led (led 2), the led 12 and all the power led on video cards (2 X GTX980TI) start flashing. Tried everything: cmos, cmos's battery, cables... No way, just silence. So I tried to turn it on with just one cpu (the socket 0 one) and it runs! But no way to enter the bios. Just show '02' 'EA' '87' and '01' theese 4 messages in loop. After some tests, it stopped to show any message!!!! I really, really scared. PSU 1500W RAM 12 GB (6X2) 2 X Xeon 5670 ssd 850 pro Windows 10 I bought it in March (2016) from Poland, used, I live in Italy, and the guy told me it has a 10 year warranty, so anyone could tell me the correct steps to find a solution? Thanks!!!  Stefano

It is possible that it is the motherboard or the PSU, do you have another Power supply that you can test with? For the second owner of the product the 10 year warranty does not stand: "The transferred warranty will not exceed 3 years from the products shipping date from EVGA"

Thank you for the support.
Tomorrow morning I will try with a different PSU, but I'm pretty sure it is the MB, The PSU is very young, bought in February...
Really bad news for the transferred warranty, I hope tu be within it, the guy told me he bought it in 2013.. Have to check it.

Thank you,
I'll check the warranty and I'll do. Hope It will be not necessary...

After many tests, I found that the issue came from cpu's.
For some reasons they stopped working:
If I test both installed into sockets, no one working.
If I test each of them in the first socket (0), it runs but can't start (bios).
I tested another x5650 cpu in first socket and everything starts.
I'm searching for a cheap x56.. to test both installed. If it starts, something must be happened and I think it should not a MB fault. But it's strange becouse cpu's was not stressed. Maybe a 'over voltage' or something like that from thundestorm or a line error?
I will report just to help someone in future.

Bad fast news, try to start the SR-2 with 1 cpu in socket 2 (1) alone... cpu fried. And the memory in first red slot become hot hot hot. No more cpus, no more hopes. Ram could be dead? If is it gone, I can try to mount it in another MB or I risk something bad (I mean, a fried ram could corrupt any hardware or just don't run?)

It sounds like a failed voltage regulator on the motherboard (which could have been caused by a faulty PSU that was overvolting something important), which proceeded to take down the CPUs and probably the memory with it. :-(

Yes, I thought and now I'm scared about the PSU, but it pretty new (some months) and supplyed well the test with socket 0 alone and it completely modular...

It really doesn't matter much how new the PSU is. In my experience. Some PSUs are just crap.

It's the Seasonic X1250W, I read some very good reviews around the net, obviously I'll try to check it.

Finally I tested psu and it seems working perfect, so I'm convinced it was only an issue of the SR-2. I'll see.
Now I'm mounting other 2 SR-2 workstations and I just have to ask a question that I didn't find in past 3ad: The manual suggest to supply the second 6-pin pci connectors of the cpus just if a hard OC needed. I connected that cables since first run, but which is the limit of the 'hard oc'? I just want to run my x5660s and x5690s at around 3,8 Ghz.
Do I need the second supply connector?
And if current is not enough for the OC, pc does not start or simply goes slowly? Could be dangerous?
I'm mounting a custom case for workstation and I would like to make it clean as much as possible, so less cables means less entropy. I just don't want to take risks.
Thanks!

The moment you are doing any OC-ing you are disabling the CPU voltage scaling, so even if you are running at stock clocks, the power consumption and thus heat will be impacted. Pretty much the moment you OC you should be adding the extra auxiliary power inputs.

Sorry for delay, Mauler... No, the broken SR-2 is gone, it burned me 3 cpu, while I tryed to test it... Every cpu in slot 2 burned immediatly when turned on the current... ... And thanks for info, Gordan! Now I'm testing the other 2 SR-2 with the new power supply and they frustrates me: they simply don't start. I mean, they start, but when they shut down or restart after bios settings, simply do not re-start. I need to push the start button since the 2 yellow led turned off, wait 5-10 seconds and then little-push the start button again and they start... Never happened withe the old broken SR-2. Sr-2s start well without isse only if Irestart them from windows in 'restart mode' but if I shut down and the current stop to supply components, I need to do the above procedure... This thing drive me crazy. After tons of hours totally fear since I discovered the procedure, I found some other 3ads about this issue of SR-2. Now I know it is another genetic issue of SR-2, and the power supply works perfectly, could be an issue of SR-2 with some kind of power supply??? Becouse the 2 SR-2 do the exatly same things. Is it very strange, no??? And now my new fear: could this issue (start, don't start, restart ecc... since the end of the life in the earth) damage the motherboards? I can suggest the EA for a new ps4 game title: 'find the flow with the SR-2' The story is just a guy who try to start and watch the window screensaver for a couple of hours without any issue. If you do it, EA give you a present: one of mine SR-2.

I'm really sorry, I know how much this thing frustrating... BUT pay attention about that is the real problem. I mean:
now I'm running 2 SR-2,
sometimes sr-2 for unknowed reason won't start, last time (1 week ago), worked well, turned off, next day turned on, nothing. Then started but with multiple screamy beeps, I thought it was died, quite sure about its dead... Just switched power off, bios battery, checked every cables ecc... Started again, no way, tryed with the 'knowed procedure' (generally don't start and 2 yellow leds shines, so you have to keep pushing the power button until the 2 yellow leds turn off, then just one little push the power button again and hope...) after some procedures it starts but can't start the second time (you know, when you clean bios it use to start and restart...) Finally it started and now is working well, but sometimes won't start and I just have to do the procedure 1 or 2 times.
About the first damaged MB, I discovered about the '1' socket died after burned 3 (3!!!!!!!!! 2 fantastic 5670 and one lovely 5650) Xeons... So you just feel lucky compare to me!!! :)
