BIOS Settings for Corsair Dominator Platinum RGB 3200 MHz on Gigabyte Z590 Vision G Motherboard


Recommended Posts

Hi Corsair Forums!

I am building a new PC with the following components...
 

CPU Intel Core i7 11700K 8-Core LGA 1200 3.6GHz Unlocked
Motherboard Gigabyte Z590 VISION G Intel LGA 1200 ATX
RAM Corsair Dominator Platinum RGB 64GB (4x 16GB) DDR4 3200MHz 16-20-20-38 1.35v
Graphics Card Gigabyte GeForce RTX 3080 VISION OC 10GB
CPU Air Cooler Cooler Master MasterAir MA620M ARGB
Power Supply be quiet! Dark Power 12 Series 850W 80+ Titanium Fully Modular
SSD M.2 Samsung 970 EVO Plus 2TB NVMe 1.3 M.2 (2280) 3-Bit V-NAND SSD
Operating System Microsoft Windows 10 Professional 64-bit
Case Corsair iCUE 4000X RGB Tempered Glass Mid-Tower ATX - Black


When installing the Windows 10 x64 OS the PC was constantly crashing until I removed 2 of the 4 RAM DIMM's. The OS has now been installed but the PC will 'Not' boot if I install all 4 RAM DIMMs again?

My aim is to have all 4 DIMMs running at the default speed of 3200MHz without overclocking (unless required?) however I have only been able to boot the PC with 2 DIMM's at the 'Auto' settings of 2133MHz?

I purchased 'Two Sets' of 2x 16GB (64GB Total) of Corsair Dominator Platinum RGB 3200 MHz and both sets have the SKU Code CMT32GX4M2E3200C16 and all other bar code numbers were the same.


I have updated the BIOS to the Latest 'Version F7b' https://www.gigabyte.com/Motherboard/Z590-VISION-G-rev-10/support#support-dl-bios and tested the following settings but they keep resetting to Auto...

  • Enabling XMP
  • Setting Gear Mode to Gear 1
  • Manually Setting Memory Speed to 3200MHz (Default Speed)
  • Manually Setting tCL-tRCD-tRP-tRAD to 16-20-20-38 (Default Timings)
  • Manually Setting Voltage to 1.35v (Default Voltage)


I have also tried different combinations of 2 DIMMs in different Motherboard DDR4 Slots (A1-B1 or A2-B2) to check for a faulty component and 'All' DIMM's will allow the PC to boot but only when 2 DIMM's are installed?

Any suggestions about how to install all 4 DIMM's at 3200MHz would be greatly appreciated! Thank you in advance!

It seems this specific RAM is not on the Qualified Vendors List (QVL) for the Gigabyte Z590 VISION G Motherboard... I will now try to exchange the RAM for a similar model on the list!

If your intent is to populate all four dimm slots on the motherboard for a total of 64GB it is our recommendation, and best practice to purchase a single 64GB(4x16GB) memory kit instead of attempting to mix two 32GB(2x16GB) memory kits as neither kit is validated or guaranteed to work in a 64GB configuration. As you have discovered attempting to mix memory kits can lead to system stability issues, prevent XMP from working correctly, or even prevent the system from booting. I suspect if you compared the VER number on both kits they would be different meaning the ICs are not the same further adding to the compatibility issue you are experiencing.

Also, you're not guaranteed to get two kits from the same PN and revision to work together.

It's always better to get all your memory in a single matched kit., or else you rely on luck to get it to work 🙂

Since Corsair doesn't guarantee separate kits to work together, the answer from support will always be to get a matched kit, or only use one of the two you got.

Edit : beaten by Notepad at it 😛
