990FX UD5 memory overclocking
« on: September 11, 2012, 11:46:57 am »
Good morning guys, today I got my new AMD platform: Gigabyte 990FXA UD5 + AMD FX 4100.

After assembling It I've tried to overclock memories (Patriot Viper Xtreme 2133 C11).... without results ! The motherboard fails overclocking even at 2133 Mhz  (Default speed and timings, 10.66x multiplier).

Instead If I Increase memory frequency by fsb (1866 @ 2133) there are no problem. I've flashed the latest BIOS F9 and F10beta... it's the samething.

I've also changed subtimings to increase stability (trrd 7), nothing to do.

In your opinion what could be the problem ? Could It be BIOS related ?

try Setting the Row refresh cycle time to 300ns or more in BIOS.
