Yesterday I assembled my new PC and I was disappointed by non-ability to use XMP with G.SKILL Trident X on this motherboard. Any memory settings except standard 1333Mhz produced triple beeps, pause and reboot. BIOS update to latest 0039 did not help. I thought something wrong with memory, but today morning I put it in my friend's ASRock Z77 and PC was booted with 2400MHz easily.
Has anybody got a successful experience with G.SKILL Trident X & DZ77GA-70K?
I use the same memory but only 2 x 4 GB and it works fine @2400MHz together with my i7-3770K-CPU@4,5GHz and a Zotac Geforce GTX 680. If I´ve tried to update the BIOS from 039 to 045 I´ve removed the GTX 680 and the RAM works only at a maximum of 1866 MHz with the integrated IGP@1600MHz. This means the MHz of the RAM is not independent from the used display adapter. After re-integration of the GTX 680 my RAM works @2400MHz again and there is no problem to use both GPUs with Lucid Virtu Universal. The GTX 680 is not overclocked and the IGP works @1600MHz.
I'm having the same Issue ... I'm very frustrated...
Headline of my config :
If I put the frequency to 2133, the windows itself is not at all stable.
(I see the famous blue screen of windows)
Did you find a solution ??
