[記憶體] Is it possible to have DDR4 ram speed 2933MHz or 3200Mhz at 1.2 V

carsonhung

I just bought the B450M Mortar Max a few days ago, new to AMD platform and no overclocking exp and knowledge.

my ram is HX432C18FB2K2/1616GB (8GB 1G x 64-Bit x 2 pcs.)DDR4 3200 CL18 288 Pi   DIMM Kit
JEDEC/XMP TIMING PARAMETERS
• JEDEC/PnP: DDR4-3200 CL18-21-21 @1.2V
•XMP Profile #1:  DDR4-3200 CL18-21-21 @1.2V
•XMP Profile #2:  DDR4-2933 CL17-19-19 @1.2V

at bios , I choose the A-XMP profile 2 , from the info of hyperX https://www.kingston.com/dataSheets/HX432C18FB2K2_16.pdf
the ram seems can be able to operate XMP Profile #2:  DDR4-2933 CL17-19-19 @1.2V ,but why my ram 's voltage is 1.384V by choose the A-XMP option at BIOS.

AMD suggest that www.amd.com/zh-hant/products/apu/amd-ryzen-5-3400g
3400G  最大記憶體速度  2933MHz
any performance improve if I choose XMP Profile #1:  DDR4-3200

Do I need other software download from AMD official page?
How to max my Vega 11 performance ?
any setting suggestion on Bios and AMD software?

Please help, thanks

呢對RAM係新CHIP, 賣點就係3200只要1.2V

加壓應該係底板自動超頻加落去,你可以自己搵返VRAM 電壓設返1.2V

   that means I should not choose the A-XMP profile by manually set it?
any B450M Mortar Max  or MSI AM4 board owner can tell me how to set it?


thanks a lot

Enable A-XMP，set DRAM voltage 1.2v

any performance improve if I choose XMP Profile #1:  DDR4-3200?
Yes, there is performance improve if using XMP Profile #1:  DDR4-3200

How to max my Vega 11 performance ?
Overclock the gpu and memory

any setting suggestion on Bios and AMD software?
enable TPM (although I have no idea any software will use it)
Enable UEFI only instead of UEFI+CSM
