EVGA SR3 Super Record 3 Motherboard Pictured

Just as its detractors thought they were done with it, and just as people started to think that attrition among some of its "popular" designers cost EVGA dearly, the company hit back with teaser pictures of the Super Record 3 or SR3, it promised back in June, it would deliver to the enthusiast community. And yes, it matches its description! The SR3 is a dual socket LGA2011 2P enthusiast desktop/workstation motherboard in the E-ATX form factor. Socket 0 is wired to eight DDR3 DIMM slots (two DIMMs/channel), while socket 1 to four slots (1 DIMM/channel).

In LGA2011 2P systems, the processor sitting on socket 0 is wired to the PCH (SR3 looks to have Patsburg-T), while the processor on socket 1 is wired to the one on socket 0 using two QPI links, closing the daisy-chain. Socket 0, apart from its 4 GB/s DMI link, has a PCI-Express 2.0 x4 (another 4 GB/s) link to supplement the DMI link, so the storage controllers don't get bottlenecked with just DMI. Both processors contribute to the PCI-Express lane budget of the motherboard. There are seven PCI-Express x16 slots, among which four are PCI-Express 3.0 x16 capable, every slot is PCI-Express 3.0 x8 capable. NVIDIA 4-way SLI is supported. This board will support Sandy Bridge-EP Xeon processors, though we don't know at this juncture if Core i7 Sandy Bridge-E is 2P capable.
The CPU sockets are each powered by a 6+1 phase digital PWM circuit driven by CPL+Volterra components, the memory is powered by 8-phase (1 phase per channel) digital PWM. Apart from the 24-pin ATX connector, power is drawn in by two 8-pin EPS connectors (one per socket), and three 6-pin PCIe connectors (one per socket, and one for PCIe slot electrical stability). Each PCIe slot can be individually toggled (disabled/enabled), by gating its power lane using DIP switches on the board. There are consolidated voltage measurement points, and one can expect the UEFI firmware to pack every option an overclocker could possibly tinker with.

In terms of storage connectivity, there are as many as 14 SATA ports (data rates aren't known yet), and a couple of eSATA ports. General connectivity includes 8+2 channel HD audio, two gigabit Ethernet connections, USB 3.0, Bluetooth, and EVBot support (the gadget could even come bundled). There's no word on the availability, but one thing for sure is that EVGA is ready to dominate LGA2011 enthusiast board market.

For some odd reason - I want that. I know I can't afford it most likely, but still..

The setup of the PCI express slots presents interesting performance questions. Since each slot has x16 bandwidth and no NF200 chips seem to be on the board, it must be that two x16 slots are connected to each processor. This would mean that setups with 3 or 4 GPUs with involve processor-to-processor communication via the QPI. I wonder what kind of latency this will add and how much performance will decrease.

It's also interesting to note that NVidia is allowing 4-way SLI without the use of two nForce 200 PCIe bridges. They were required in all previous implementations even if enough links were available to support 4-way SLI without them.

Steven Bthey do understand two LGA2011 CPUs, cannot OC in an arrangement like this, right?
What arrangement?
The board is designed for OC-ing 2 CPU's most likely Xeon as was the case with the SR2.

building our own destruction

Insanely unecessaily powerful cpus + overkill boards..... one day thanks to companies like intel and evga. Some overcloker is going to look up in horror as the worda I AM AWARE flash across his 30 inch led monitors

But beside that its The stuff techno dreams are made of......

twicksistedMadness... I like! Though if you have the cash and inclination to build a rig using two CPU's and all those PCI-E slots this board offers, youll probably want the PCI-E slots spaced further apart so that you can put decent gfx cards in all of them.

thats a bit strange...
Depends on what you're filling the slots with—not everyone will plan on using it just for bulky video cards. For my next workstation I plan on using this with PCIe risers to mount some cards away from the board.
20mmrainCome on EVGA lets design something a little different here. It makes someone think you like using parts from the last year and are having financial problems. Don't get me wrong.... it probably does some really cool stuff.... but Gees EVGA mix it up a little.
It's a dual socket R motherboard with seven PCIe slots and more eight-channel DDR3 RAM capacity than you can shake a stick at, aimed at enthusiasts. How much more uniqueness do you want?

Odd only 4 dimm slots on the second socket, I wonder if this means there is a bandwidth issue ?

Jacob said that having 12 DIMM slots on this board was on purpose, so it could match the number of DIMM slots on the SR2, and people (current SR2 users) with their fine-tuned 12 DDR3 modules could just carry them over.

Having an asymmetrical amount of memory per socket in multi-socket systems doesn't lead to instability.

Good to know, but for the people this board is aimed at, I can't imagine 4 more dimms is really an issue.

But it is nice to see EVGA thinking ahead for it's customers.

Droooollllll, 2x xeons yes please. Now this is what I call a desktop gaming pc.
Just need a many AMD7890's as would fit in there. :toast:
Great 8x slot spacing.

This is a nice alternative to Opteron's and some optimizations issues they have for heavy work loads.

So nice to see 1 competent motherboard manufacturer that still can they way Apple used to back in PowerPC days.

I wonder if this nand + dram hybrid memory would be ready for this SR3.

btarunrThe SR3 is a dual socket LGA2011 2P enthusiast desktop/workstation motherboard in the E-ATX form factor.
Isn't this HPTX like the SR-2? Planning to get one of these, so was hoping to be sure it was compatible with the case it's going in.

repman244You totally missed the point of this board...but good luck with overclocking your workstation :laugh:
They missed out the name. That is not that super. There are better workstations.
What would be the other workstations name? Super duper? :laugh:

as far as i know you cannot OC LGA2011 xeons, as far as i know they have locked BLCK and Multi. but maybe its designed for one xeon and one normal CPU, but there are two LGA2011 sockets. I remember the ASUS danshui bay concept, shamino one of ASUS's engineers explained why dual LGA2011 OC would not work, he made a diagram, i saved it if you want to see it.

Perhaps EVGA found a workaround.

Aleksander DishnicaThere are better workstations.
For example?

And this isn't really intended 100% as a workstation either. The board is intended for dual CPU overclocking the same way SR-2 was...

Agreed, if you can't OC both CPU's no point, much better to buy a server board.

Steven Bthere is no work around for a locked CPU, but here is what shamino posted up at XS:

SHAMINO made this, not me.
imageshack.us/f/200/danshuibay.jpg/
Perhaps when he made that he was basing it on the assumption that the SandyBridge-E processors would be like the Sandybridge processors, and they would have one BCLK that couldn't really be raised. However, we now know that Sandybridge-E processor have a BCLK that can be adjusted without affecting the rest of the system, using a kind of BCLK gearing setup that uses another multiplier to adjust the BCLK that affects just the CPU cores and not the rest of the system. Of course the Xeons might not allow this to be adjusted...

that is true, but those dividers might not be available for use on a Xeon, only time will tell, but then ASUS woudl have known and made a dual board like this one for display. no one really buys these boards they are just to show off their engineering prowless, much more of marketing thing than anything else, Danshui Bay will never see the light of day, but i am sure this will, as it is practical and the SR-2 didn't do that bad.

Yeah... every 2P (and occasionally 4P) system I've ever owned just sat on my desk running the pipes screensaver :rolleyes: ;)

Correct, that is what I said. I'm not sure that ASUS would know at the time of his posting that these processors would have that multiplier, and the early engineering samples might have them locked but the retail/later engineering samples might no. As you said, only time will tell. I couldn't find the thread you were talking about on xtremesystem, so I don't know when it was made, if it was before or after the news that locked SB-E processors could still be overclocked.
