I recently purchased a computer from CyberPower and am attempting to understand how to achieve 32GB of RAM to operate at 2133 MHz.
Current configuration:
- Gigabyte GA-990FXA-UD3 R5 motherboard
- AMD FX-9590 4.7 GHz AM3+ processor
- 2 ADATA 4GB DDR3-2133 XPG V3 RAM units (total 8GB)

I planned to upgrade from 8GB to 32GB by acquiring a 32GB G.SKILL Ripjaws X Series DDR3-2133 kit (four 8GB modules). Note: CyberPower offers 32GB of G.SKILL Ripjaws X DDR3-2133 for this system. During my conversation with their support team, they confirmed that the same memory type would function correctly with my motherboard and CPU.

The issue is that my system only recognizes 32GB of identical memory, despite being told it should work. When I enabled XMP in the BIOS, using Profiles 1 or 2 resulted in a boot failure message. My choices are:
- Apply optimized defaults, then boot
- Apply optimized defaults, then reboot
- Enter BIOS settings

The RAM functions with two 8GB modules at 2133 MHz (using Profile 1 or 2), but using all 32GB is problematic. To verify compatibility, I’ve tested every possible combination of the four sticks at 2133 and confirmed they all work. The BIOS is also up to date (version F2).

Currently, the RAM operates without XMP enabled at 1600 MHz. My goal is to enable XMP at 2133 MHz.
What I’ve tried:
- Disabling XMP and increasing the multiplier beyond 8 caused a boot failure. (Multipliers: 9.33 for 1866, 10.66 for 2133)
- Keeping multiplier at 8 with XMP off, adjusting BCLK and CPU speed to maintain 4.7 GHz. (Used 235 bclk, 20 cpu cores.) Any change pushing RAM speed above 1600 led to failure.
- Raising DRAM voltage to 1.60V while keeping XMP off. The BIOS indicated it was using 1.50V, but I’m unsure what this means.
- Adjusting timings with XMP at profiles 1 or 2. Still encountered a boot failure.

I’m seeking a way to ensure all 32GB sticks cooperate at 2133 MHz.

I don't think the motherboard will support much beyond 2k and I question if it could even come close with a 9590 included.
Make sure airflow is maintained over the VRM when using the 220W CPU.
When reviewing Adata's compatibility list, only 1333 RAM is shown as compatible for that board.
I placed this in our Overclocking section in case anyone has useful tips.
Good luck.
