Hi Guys!

I've been diging for info on my question, for month now. PLEASE help me out here!!!
I've built an APU system for a friend, to utilize the built in graphics - because the budget.
We encounter random freezes and BSODs, sometimes we can reproduce the error with some games, sometimes we can not.
The errors occour at any frequncy above JEDEC 1600 - but since it's an APU it really needs a higher memory speed to be set - to provide more FPS.
XMP profiles, manual settings with slightly more loose timings, a tiny bit more voltage... NB overclocking, NB overvolting, nothing helped, eventually the system freezes up, sometimes it needs hours, sometimes days.

The specs:
- AMD A10 7870k
- MSI A88XM Gaming - last 2015 BIOS update - this week I want to try out the new 2016 one (not hoping much)
- Kingston HyperX Beast 2400 Mhz, cl11, 2x4gb ( HX324C11T3K2/8)
- Thermaltake smart se 630w
- WD Black 1TB HDD.

Yes, I know (now), the RAM that I choosed to use was not listed, on the compatibility page. But I've compared everything to the listed Hyper X RAMs back than, it seemed to be just fine. Today I realized what I must have looked over. I copy a URL to one supported Beast memmory here.

If you compare it yourself you'll see no big differences. I've only found 1 today.
What I choosed has an I/O clock - fCK - Base Clock @ 800MHz
The supported one's @ 667MHz
I've looked in some other supported RAMs and I've found the same base clocks.
As I recall we only had the 800MHz version available for purchaces here.

My questions are simple, is there anything I can do to get this setup working? Or we should ditch this RAM and get one pair of this Corsair (wich is also NOT on the list but a slightly bigger version does). At least it's base clock seems right because it's scales from 1333MHz. Could this be the key to the problem? Why can't the system utilize the faster clock speed?

Thank's for reading, I realy hope you can help to end this problem once and for all.

Thank's in advance! Sorry for the baaaad english... :)
 
Solution
As I found no actual help, I'll try to share my thoughts with unfortunate people like me. So the solution was to buy another pair of RAM. Actually it's a Corsair CMY8GX3M2A2133C11R. Cause of the problem... I'm not exactly sure, but all the RAM on the MOBO's compatibility list are capable of 1333 MHz JEDEC - and what that means they have a baseclock of 667MHz instead of 800Mhz. Turns out no actual information is available on the web in this question.
Now the system runs flawlessly.

MY ADVICE TO EVERYYONE - if you buying a new mobo make sure you check all compatibility listing for it. - In my case this RAM was on the list - but I could use everything that has a baseclock 667. If you want to make sure of your mobos base clock limits check...

Hi!
Sorry for the late reply.
I've set everything you posted. Not even booted up this time. The bios went back to default, beause of 3 failed boot attends.
We need another solution. :(

If you want to make sure of your mobos base clock limits check all the corsair and kingstone RAM they tested with it - theese manufacturers provide data about the RAM's baseclock and XMP profiles. Maybe this will be no issue in the future - but maybe someone profits from my labor.

Cheers
