ASUS motherboard underclocking Kingston memory

Hello everyone!

My ASUS mobo underclocks RAM CL7 1600 to CL9 1333. After I had contacted Kingston for help, they told me that the RAMs aren´t licensed for ASUS and nothing else, which is weird, because my mobo supports speeds up to 2133 MHz, but Kingston does not list any other HyperX RAMs than Blu 1600 CL9. The other problem is when I force them to 7-8-7-20 and 1600 MHz, I sometimes get BSODs and Windows 7 blames it on RAM.
So any suggestions?

Cheers W.ut

There was no problem with booting the PC on 1333 Mhz 9-9-9-24, however there would be no point running mid-range RAMs on low timings. I have been looking through reviews, and this site http://www.thinkcomputers.org/kingston-hyperx-limited-edition-ddr3-1600-4gb-dual-channel-memory-kit-review/2/ had CPU-Z stats. I will post mine compared to theirs.

MB: Asus M5A97
CPU: 3,9GHz (stock 3,3Ghz) AMD FX-6100
RAM: 8GB Kingston 1600MHz CL7 Lim. Ed.
GPU: 1GB GDDR5 ATI/AMD RADEON HD 7770 OC Ed.
PSU: 600W LC POWER 2.3 Ed.

It does, but I think I got OCMP disabled, which btw configures the profiles. If everything is left on AUTO, default settings are 9-9-9-24 1333MHz.

I will try enabling OCMP and see what it does, but I do not think it will recognize the XMP profile correctly since the RAMs are not certified for M5A97 mobo.

I took a look in your manual, set the AI Overclock Tuner to D.O.C.P. and then you should get a DRAM O.C. Profile option which should include a DDR3-1600Mhz setting, which should set it properly for your RAM. I don't think RAM needs to be "certified" for a MOBO for XMP/D.O.C.P. to work.

BTW I did not know what the AMD equivalent for XMP was, looks like it is this D.O.C.P., or DRAM O.C. Profile.

Yeah DOCP was DRAM profiling. So the profile is set, nevertheless I still think my MB gets the timings wrong. For example command rate is 2T(N) but the guys from the review had it 1T(N). Screened the whole messing around with UEFI, I will upload them here.

Well, I am not too familiar with RAM timings and such, or the command rate, but the few seconds of research I did led me to believe that the command rate can be toggled by the user, it's just not all RAM will operate correctly at 1T. I would guess the DOCP automatically sets it to 2T, it sounds like the difference is relatively minor, but as I said, I am not too familiar with the topic.

It happened from time to time in different games, so I could not track the certain conditions for them. They may reappear after some time.

I was only BSODing after long gaming sessions or movie rendering, that was real pain in the ass, crashing in the middle of 30 min render. It never really happened, while browsing the net or other minor actions. And happy holiday to you too!

After gazillion years of troubleshooting, it seems like two RAM sticks were faulty. I will probably get them RMAed.
