For Christmas I received a kit of Patriot DDR3 PC3-17000, 2133 mhz. timings @ 2133 rated at 11-11-11-27, and 1.5v

I am able to run the ram at 1600 mhz, with timings of 8-8-8-24, at 1.5v with no problem, and the system reads all of the 16GB. Anything beyond that speed, and I am unable to boot.

using the XMP got me *almost* to the windows desktop, but it bluescreened there. I'm fairly adept in the BIOS, and know my way around pretty well, but this one has me stumped.

Is it possible to run this RAM at 2133 mhz on this motherboard? As yet, I've not been able to get it to even 1866. The motherboard's spec page states: "Supports 3 channel DDR3 2000+ memory" -- my RAM's packaging says "quad channel" on it. Does that matter?

Thanks for any and all help!

> Your ex58 board has a default ram speed of only 1066, so you shouldn't be surprised
> that you can't go that high.

From the Gigabyte ex58-UD3R manual: "Supports DDR3 2000+ memory"
