im looking in to buying this MOBO

http://www.newegg.com/Product/Product.aspx?Item=N82E168...


and this ram kit to go with it (possibly 2 sets for 16gb)


http://www.newegg.com/Product/Product.aspx?Item=N82E168...

from my understanding when i start up its going to run my RAM at 1866 unless i pop over in the FSB and set it to 2133
my question here is:
(1) will i have any errors running the ram until the point where i OC it?
(2) is it safe to OC it to 2133?
(3) what are your thoughts and comments?

ill be using a zalman heat sink with a 900w antec pro gamer PSU

I'm fairly certain that the default DRAM frequency on this mobo is 1066, because all other frequencies higher is considered overclocking. You should be aware of the limitations with AMD CPUs and the RAM speeds/frequencies they can support.

In a nutshell, the frequency you can actually attain depends on the amount of DIMM slots you're occupying and the rank specification of the DIMM. So before purchasing your second set of RAM, make sure you read your mobo manual to see if you'll be able to attain the frequency you desire with 4 DIMMs.

Since you didn't list what CPU you're using, I'll assume you're using the one in your sig. That said, this http://support.amd.com/us/kbarticles/Pages/ddr3memoryfr... should help explain the limitation mentioned.

It will run at the default speed for your MOBO, so yes, it will run, just at a lower speed.

Also, I am not sure how it works on AMD MOBO's, but it does list 1866 and 1600 as supported speeds without the associated (O.C) label, I know with Intel CPU's this generally means those speeds are supported by XMP which is a profile system that has pre-set settings for certain RAM speeds. I do not know if there is an AMD equivalent, it looks like it after looking at the speeds on there. What I am saying is, you would have to OC to get to 2133, but the other speeds should be supported by some sort of profile or pre-set.

After reading through your mobo manual, I retract my previous statement. This mobo uses the SPD for default, not a predetermined value. SPD is Serial Presence Detect, which is found on the RAM modules. In other words, the default value for this mobo is dependent on what RAM you install. So, for you, the default will likely be 1600.
