As the title states my EVGA SR2 is not booting with dual cpus or one and the only time that the post code led lights up is when the cpus are both removed. The board has power and lights up but does not have and video. Can anybody enlighten me on whats up, and if it is dead or not. Thanks in advance.

2x e5645 6 core @2.4ghz
4gb of ram (2gb per cpu for now)
thermal take tough power 1000 watt psu with 2 cpu power conectors
and the post code is blank, no beeps or anyhting
First time ive ever tried booting it
and ive tried everything on anot5her system and its all worked
might be that the board's current bios does not support those cpus. does it start with only one cpu? if so you might be able to bios flash to latest bios revision and then try it then.
I think just about every time I had a problem component on the SR-2 there was an led light telling me which point the failure was at, or a POST code to help... so that doesn't sound good.
I would check all the jumpers on the board and try in single socket mode (although sounds like you may have already tried that).
RAM can also be a source of headache for this board. Only a few of the many different RAM chips I tried in the board have ever worked.
I might also try sticking the RAM in the first slot on the second channel in the board, just to make sure there aren't any misbehaving slots. For some reason the RAM channels on mine are super picky and don't always see the installed RAM until I really have the heatsinks on just right (and the phase of the moon is aligned
).
Also I think a w3505 would never work in this board even in single socket mode due to the bus configuration difference (singe QPI, must be dual QPI), so I would eliminate that from the testing. An e5550 should be fine even on an early BIOS, however.
I just re-read your original post and i did have this same exact problem with my rampage 3 extreme. it turned out to be that it was the stepping on my 990X. it was B1 and the board didnt like that stepping at all.
Ok, I have 2 questions, what's stepping exactly and what ram should I be using that would work, I've tried Kingston 2gb sticks and some other random stuff I had laying about. I bought the board with the processors and ram and it's still giving me trouble.
stepping is the revision of the CPU itself. it might be that your cpus are an older stepping and the board does not like it. the EVGA x58 classified and x58 sr2 were known to be very picky with hardware. its very possible that it either hates your CPU's or hates your RAM. i recommend looking on the motherboard page from EVGA and seeing their supported CPU and RAM list. you may have to source another pair of xeons with newer steppings but luckily x58 xeons are very cheap now so that wont be hard to do. id also recommend using RAM that is confirmed on EVGA site for SR2.
The problem youre having is that the board is failing to POST properly. everything turns on you get all motherboard lights etc but no video. that means it cant POST properly. this is either wrong cpus or wrong ram. try changing ram to known supported from the QVL on motherboard page on evga site. if that does not work then source CPUS with known newer steppings that are NOT B1
1Have not used EVGA out of warranty service myself but they are VERY helpful i would send them an email asking them about your problem you might get a good solution. Not sure it would be cost effective to send it in for out of warranty service as the SR2 is pretty old now but maybe if the price is right.
I had called them about the problem and they didn't have a solution other than to send it in for them to look at it. They said they have a free quote and it is $65 an hour so if they can repair it in 2 hours it would still be much cheaper than buying a used one for 600 on ebay.
Is b1 stepping a known issue because the cpus are on the supported list and alot of them are b1 as far as I can see from checking what cpu would you recommend I try
Were the CPU's removed when you received the SR2? (possibility of bent pins?)
Are you 100% certain the PSU has no issues/do you have another PSU to test with? I have had headaches in the past where I had weird behavior / no post due to a failing power supply. Problems with the either of the power connectors on the board (loose/bent at an angle)?
If these CPU's were installed already, the seller notes the board previously worked, and the PSU is good, then this thing should post. Failing that, you have extremely unlucky timing for buying that board, the seller was dishonest, and/or the SR2 could have been damaged in shipping (I know from experience - I have had a lot of ebay purchases come to me badly packed and without ESD bags).
In any case, I hope you get it sorted or EVGA support can repair it! IMO SR2s are the most unique/awesome motherboards ever made.
The board came with 2x e5645 and the seller said it worked, I bought it off of someone relatively close to me so I just wentered and picked it up, they said it worked. The psu works fine and so do the cpus on another 1366 board I have.

I was just reading back through your posts, since you did the BIOS reset have you booted with a single CPU installed in the CPU0 socket, a single stick of RAM, and the jumper somewhere at the bottom set to disable CPU1. I'm sure you probably have, just trying to think anything else to try before going to EVGA.
I have an SR2 and am quite familiar with it. I had a failed boot the other day and the debug LED was blank. I wouldn't panic yet
Can you check the following things, CPU 1/0 enable pins : PCIE jumper enable/disable pins
Also you need to plug in 6 pin power to just above first PCIE slot for PCIE power or you will get nothing working in top bottom half of slots.
Also 8 pin AUX powers for each cpu core near sockets. Don't forget also memory stick placement. I would download and review manual from evga to cover all these.
Alright, so i didn't see if you mentioned this or not. Is it installed into a case or just sitting on a bench?
Can you test mainboard on bench with a cpu in socket 0 and socket 1 empty, 1stick of ram in dimm slot 1 (2nd slot from cpu 0 - first red slot near cpu0) only 1, 8 pin power for cpu 0 - No video card installed - and see if you get a beep code or debug LED light?
Bizzare, did it come with cpus installed? Have you checked pins in sockets?
You only get debug led lit when cpus are not installed?
Also have you tried switching the bios switch?
