Yep Q3QN

you will need to flash your bios with modded A50 bios .
Then do the jumper switch and set the volts .

Hi EVGA_JacobF,
 
I'm desperately trying to draw your attention to the problem of booting with 96GB (12x8GB) of memory. I have opened a thread on this subject (and found another one from a couple of years ago) which doesn't seem to help drawing attention from any of EVGA personnel.
 
I'm very pleased with the fact EVGA is releasing new versions of SR-2 BIOS this late in the product lifecycle. I must admit this is a very unusual (yet much welcome!) practice amongst motherboard manufacturers.
 
Let me try to explain why this is such an important issue: I realise SR motherboards have been designed with enthusiast users in mind. However, they're about the only consumer grade platform suitable to serve as virtualisation server and/or scientific calculation platform. With SR-2, I was able to build a dual Westmere 3.6GHz (and climbing!) virtualisation server for mere 2.7K: 2 x used X5650 ES off eBay for $560 (together), a new SR-2 off eBay for $450 (including shipping to Australia), ~$700 for the case and 2 x CPU Corsair closed loop watercooling systems (H80i) and less than $1000 for 12x8GB memory sticks (assuming they're working) and a platinum PSU. A comparable "proper" server would cost well above 5K mark (CPUs alone would amount for >3K) and wouldn't allow for any overclocking, not to mention differences in aesthetics and noise. However, for this machine to truly serve its purpose, it's adamant it's able to use more than 48GB of memory!
 
Is it too much to ask EVGA to figure out why the board is able to CONSISTENTLY boot with 96GB of memory after clearing CMOS, but not when ANY BIOS settings are saved (even the default ones)? I really hope you won't abandon those people who spent so much money on EVGA products, just to find out they're unable to do what they intended to do.
 
Thank you in advance!

In the absence of a publicly accessible bug tracking tool, I think we need to start keeping a track of BIOS bugs that various people are encountering. For example:
 
1) BIOS profile doesn't save the default boot GPU - I only just discovered that one this morning.
 
2) Profile 1 / Profile 2 saving issues - come on, guys, this type of issue should never have made it past the v1 BIOS release QA.
 
3) Booting issues with 96GB of RAM (the CPUs support more, and dual ranked ECC DDR3 x4 RDIMMs of 16GB are available for up to 192GB, too).
 
Plus the ones I mentioned earlier in this thread. Bugs like this might be ignorable if you are trying to compete with the bottom of the market with products targeted at people that will buy anything as long as it's cheap. It is definitely not acceptable at the top end of the market where the SR-2 appears to be targeted (by price tag if by nothing else).

Hello,

The solution for error message CMOS CHECKSUM BAD and Not enough space pci device.

In my case I disable the port pcix No. 5.

ca solved my case I think with more ports pcix use the bios does not happen again to assign error on boot up then.

@eek142: Does this happen at non-overclocked settings?

I wouldn't discount a possible marginal hardware problem, considering that nobody else seems to have reported it. Are you running ES Xeons or real ones?

96GB of RAMs are working on this board without any problem so ****? of course, 192GB would be better, i dont know why 16GB modules are detected in this board with only half capacity...maybe really bios bug, which would be nice to solve...
 
to EVGA staff: is there any possibility that this new BIOS are making boards dead ? we have three SR-2 boards, one is two years old, works ok until now with A56, flashed A58 few weeks ago, works OK now too. but also we have two new boards (bought feb 2013), worked two months with A56 OK, week ago we flashed A58 and in last three days both boards are dead. or better said, no devices are detected in pcie slots one, two, three and four. no vga, no raid card, no network card...nothing. but the slots are lighting red, so they are recieving power. slots five, six and seven works OK. all three boards are watercooled, so heat should not be an issue. slots are no more working with older A56 too. when the vga (low profile 5450 ati) is in slot 1 - 4, bios post code writes 2E error and there is one short and eight long beeps, so definitelly "not detected video card". of course we tried another PSU, many vga cards...another cpu...strange. we will have to rma these boards probably...but i just dont understand why they died after two months of hard work, both in few days.

the cases are supermicro sc219 http://www.supermicro.com/products/chassis/2U/219/SC219A-R920LP.cfm and it looks like this in the case http://www.jscomputers.cz/Detail%20sestavy?arg0=158158 (for pictures scroll down).
 
it worked two months all ok, so i am afraid it is not fault of the case itself, but of course, i tried both boards on the wooden table too, outside the case, with same result. really strange...

Can't believe I overlooked this, my BIOS was from 2011 lol, hopefully this will fix my random restarting issue -_-

Very Grateful that updated bios is here.
Can't wait to see memory fix. 
I am very hesitant to try this given report of couple boards failing.
Any other people having issues?

Awesome builds. Any update/resolve for those non-functioning boards after the A58 bios update. Let us know how it went.

I HAVE A PROBLEM.
 
i cant install a tesla m1060.
 
i put in a slot, i install drivers, but... i have an error message after rebooting:
"No enough system resources to complete the API call"

Agurn3D, sorry to hear you are having these issues, I will be following up via email to see if we can get this resolved for you.

thanks, but I think the problem is in the card, I've had in the past on this motherboard 4 Cards, making a total of 6 gpus.

Now they need to update the RST code so I can RAID five 3TB drives.  It sees them fine, but initializes in AHCI mode.  I cannot create a RAID volume in either the BIOS or in RST under Windows.  Windows see's all 5 drives as blank 3TB drives.  Now if I go ahead and plug the 640G drives in, the RAID comes right up.  I was disappointed, although BIOS 56 was from 2011.  I saw that there was a release from this year (58) and I was hoping this could have been fixed.  No love.  I emailed support.  Got nowhere.  Come on EVGA, there's a LOT of people who use these boards.  I am even looking for a cheap used one for a second test machine / workstation.  I can't be the only person who has tried to RAID5 several 3TB drives on the Intel ports of an SR-2.  Please tell me that us "storage minded" folks can look forward to an update to resolve this.  Or maybe a No-Fate type of third party fix.
