but i can manage to boot with 2000 mhz
i try to put manual cl 8-9-8-24 with 1.65 and nothing i load the asus xmp and nothing. i disble de mem lock profile. the pc will boot with mem @ max 1600 mhz. i try oc i left it on defoult and still no luck.
i need some help pls.
best regards

Have you overclocked the CPU? With such high speed RAM you usually need to increase the BCLK to get it to run at rated speed.

yes i ok 4.2 with 2005 for mem . and still no boot.

what is the core speed, voltages and bclk?

have you set the memory controller voltage?
forgot the actual name of it

NAM_killer · 12 Sep 2010 at 22:22

You should set the vcore manually, the qpi/dram manually and the cpu pll voltage manually aswell.

Start with a low overclock and work it up along with the voltages to find the right combination

yeap did that and still no luck. the most in booting with 1600mhz

You may want to try each stick individually and see how it runs.

If one stick doesn't hit stock speed (2000MHz), but the others do - then it's RMA time. If they all hit 2000MHz individually then its probably to do with the Integrated Memory Controller (IMC) on the CPU - which is just bad luck and not much you can do except run the RAM sticks at 1600MHz (or send them back and get some £120 1600MHz ones).

i will try them tomorrow, one by one.

q6600 · 14 Sep 2010 at 08:42

i try last night and no luck none of the 3 stick will boot @ 2000 mhz

q6600 · 16 Sep 2010 at 14:48

well i had bad luck and i have to send the mem back to o'c. they gime me a rma wend and friday i will have my new mem. thx a lot o'c.

i got today my new mem from o'c ( great service o'c) i was realy happy, i put the mem in pc, start the pec all ok 6g in bios etc, i put the xmp on 2006 mhz save and restart, and nothing same problem, i try again oc manual or auto, still nothing. after one hour i went on asus web and i saw a new bios update 1005 i think it was since few days on the web. flash the bios and since then my mem works just fine with auto setings.
i am sorry to truble you o'c it was asus fault.
best regards
