Post by: Oxezz on April 04, 2013, 05:01:16 pm
uhm, Hello...
As the title says... I already have searched for similar problems on forum, i found a couple i read them but i couldn't make my ram run on 1600mhz.
I also tried to change the timing,multiplier,voltage still nothing its like resetting to default.
Here's some info...
Motherboard: 990xa-ud3 rev 3.0 (updated to lasted bios ver.)
CPU: AMD FX 6300 black edition.
RAM: Kingston hyperx blu 4gb ddr3 1600mhz (single channel - part num: KHX1600C9D3/4GX ).
OS: Windows 7 64bit.

You wrote that you tried to change the timing,multiplier,voltage still nothing its like resetting to default.

There are a few steps involved.
First, set the System Voltage Control from Auto to Manual.
Then change DRAM voltage from Auto to 1.65v for that particular memory.

Second, In the Motherboard Intelligent Tweaker, M.I.T menu you need to change the
Set Memory Clock setting from Auto to Manual. Then you can set the Memory Clock to X8.00

Third, you go to the DDR3 Timing Items, change that from Auto to Manual. Then set Command Timings to 2T. Then set the next four settings beginning with the CAS# Latency to the recommended timings (9-9-9-27).

Save and Exit BIOS.

990xa-ud3 rev 3.0 is using UEFI bios.

Here my settings:

I don't know maybe is compatibility problem.. I also tried Memtest86 i let it about one hour and some minutes, 2 tests passed with no errors...

It's okay i fix it.. I just removed the cmos battery for 5 minutes  and after that i enable the X.M.P profile now am running normally at 1600MHz. Sorry for the inconvenience  ;D
