I currently have the following setup, and I've run multiple Prime95 tests (blend, large FFTs, small FFTs) over several hours without any errors, so I'm pretty confident that the system is rock solid stable as it is currently configured.

AMD Phenom II X6 1100T @ 4 GHz
ASUS M5A99X EVO w/ NB and HT @ 2800 MHz
Sapphire Radeon HD 7870 XT 2GB w/ Boost
G.SKILL Ripjaws X Series 8GB (2 x 4GB) DDR3 1866MHz (9-10-9-28-1T)
Creative Sound Blaster X-Fi XtremeGamer Fatal1ty Pro Series
Corsair TX750 750 Watt PSU
Samsung 840 EVO 500 GB SSD (OS and Applications)
WD VelociRaptor 600 GB 10,000 RPM HDD
WD Black 1 TB 7,200 RPM HDD
Cooler Master HAF 932 Advanced
Cooler Master Seidon 240M

I'm contemplating adding another set of G.SKILL Ripjaws 8GB (2 x 4GB) memory, but if I do that, I will be using all four memory slots on the motherboard. My main question is, will this motherboard (and CPU, if that's applicable) be able to support a 16 GB (4 x 4GB) setup? I've seen some other posts where people were unable to POST when using all four slots unless they let the memory default to 1600 MHz (which I believe is the 1100T memory controller's max speed without overclocking). Before I plunk down another $80, I want to make sure that this configuration will work. I would appreciate a bit of guidance here. Thanks!

I know that technically the motherboard supports it, but what I specifically want to know is whether I will be able to run all four sticks at 1866MHz (or faster), and also maintain my current timings. My apologies, I should have been more specific in my original post.

Okay, so I take it I shouldn't have any issues, regardless of the speed I'm running the sticks at, as long as they are listed as supported by ASUS. For some reason I thought this might be more complicated, but apparently not :)
