Question 1

Is this mb compatible to Intel Core i7-4790K Processor?
Jae

Accepted Answer

I haven't tried, but I'm absolutely sure it would be, it's the right socket, and the chipset is powerful enough to avoid bottlenecking with cpu's even more powerful than that one.

Question 2

Does this motherboard support ECC memory?

Accepted Answer

I am not sure myself but the manual states:

Supports DDR3 2933+(OC)/2800(OC)/2400(OC)/2133(OC)/1
866(OC)/1600/1333/1066 non-ECC, un-buffered memory

So from the manual it looks like no.

Question 3

How much power does this consume? (If it motherboards don't use power, only the components, I apologize- I don't know much about computers.)

Accepted Answer

if you have all the sata occupied and two gpu all I can say is a lot.

just to give you an idea I have 10 ssd and 4 2tb hdd on the lsi controller and 3 ssd and 3 4tb hdd on the intel along with 2 r9 290x cards in xfire. and had to get rid of my 1000 watt psu and with a 1600 watt have my 4770k over clocked at 4.2ghz and ram running at 2666 MHz have had this board for almost a year now and love it!!can't wait to see what asrock will do with the x99 chipset. hope they load it with sata.

Question 4

If I were to build this as a server cpu do I need to have a server ram or it will take any ddr3 1600 ram dual channel?

Accepted Answer

There is no "server ram" per se, it is all just specs of ram. The issue with this is, in terms of using as a server, that you only get 1 16lane slot, and once you put in another card it is chopped up and gone. That is more important than the ram at this point. When I get a server, lets say a supermicro, I have a lot of 16 lane slots to use for 10gb inet, fibre channel, etc. all running at full speed.... GPUs ... whatever.

Ram spec is in the product sheet. Any of those will work well.

Good luck!

Question 5

can sas be used for hooking up sata III ssd or hdd?

Accepted Answer

Yes.  The SAS ports are used for either SATA drives or SAS Drives.  The SAS ports can also host multiple raid setups

Question 6

Would you use the SAS connecting points for your SSD's & HDD's?
Will they run fast on these hook ups than on SATA 3? And do they require special SAS cables?

Accepted Answer

You can run SATA drives on the SAS ports, all you need is a SATA cable, but they only go to 6 Gb/s not 12 as SAS would. Works great runing SATA, it's what I use them for.

Question 7

Does this board support quad-SLI? And it says 2500+, that means that my lovely 64GB arsenal of 2933s will work, right?

Accepted Answer

Yes it supports 4 way SLI and Crossfire just fine. Memory should work also.

Question 8

What is the size of this? Need the measurements.

Accepted Answer

It's 10.5" wide and 12" tall. So not quite standard EATX but it did have one more hole to mount it.
