MSI A88XM-E45 BIOS or bad RAM? Help me

Thank you Calvin!
This RAM is ok for my APU and Motherboard?

G-SKILL Memory PC ARES 2 x 4 GB DDR3-2133 - PC3-17000 - CL9 (F3-2133C9D-8GAB)

On memory support list of motherboard there isn't this RAM http://www.msi.com/support/mb/A88XM-E45.html#support-ocmem

I have to overclock something?

Thank you

Hi, I update the thread, so:

- AMD A10-7700K Radeon R7, 10 Compute Cores 4C+6G APU - 3.40ghz (34x100.00 mhz)

- A88XM-E45 version V25.6 (E7721AMS), the latest BIOS version on msi website

- I bought new RAM -> G-SKILL Memory PC ARES 2 x 4 GB DDR3-2133 - PC3-17000 - CL9 (F3-2133C9D-8GAB). It's a kit for dual channel.

- Current DRAM frequency 1600 mhz

- Installed in black slots (2/4)


With these RAM I have less problems but always something doesn't work..

Just installed (RAM arrived Friday) my PC detected always and only 4GB in BIOS instead of 8GB. In windows 7 64bit there were 8gb total but only 3.46gb usable. In CPU-Z memory was in single.


Then I removed battery for 4-5 minutes and BIOS reset (I have changed date and hour).

In this way finally in BIOS I had 8 gb! Windows 7 tells 8gb in total and 6.96gb usable, in CPU-Z dual channel.


I thought had finally solved the question..and instead after 1-2 hours BSOD..

Error BSOD often change, sometimes is about "win32k.sys PAGE_FAULT_IN_NONPAGED_AREA", or the last error was:

This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.


and another before:

Other times instead I haven't BSOD but PC freezes, I have colourful lines and I have to reboot PC because all is stuck..

I thought to a problem of Windows 7 and drivers (with BIOS Update I have reinstalled the latest drivers from MSI website but maybe I have done some mess, so I'm trying to install Ubuntu). And also audio in frontal panel doesn't work more, I have to put headphones behind the computer.


But the thing very odd is that sometimes in BIOS I see again only 4GB!! Almost always after BSOD: BSOD, reboot, 4GB in BIOS. I turn off the computer for 3-4 minutes and again I can see 8GB..

And if I play to games (for example The Sims 4), temp of CPU arrives to 74°C! (from AIDA64).

I don't know more what's the problem...I try to clean fan of CPU now..
