Hi Guys,
First AMD build here, going with a Ryzen 5 3400G on a Gigabyte B450I AEORUS.
Looking at what RAM to add, the motherboard is supposed to run up to 3600MHz memory modules in overclocked mode.
So I was about to buy some 2x 16GB Patriot Viper4 3200MHZ / CL16 modules (~$110) when I saw the following offer:
2x 32GB CORSAIR Vengeance RGB PRO Black 3600MHz / CL18 for less than $170
Not that I need that much memory, but I pulled the trigger on the Corsair because of the low price. (Will have to deal with the RGB but that's another story)
I was a little worried with compatibility as there is no 32GB module present on the Gigabyte QVL https://download.gigabyte.com/FileList/Memory/mb_manual_b450-i-aorus-pro-wifi_picasso.pdf sheet, and I don't even find that specific RAM on the Corsair website...
I am anyhow able to boot with both RAM sticks plugged in which is already a nice thing!
But looking at the memory settings in the UEFI BIOS, here is what I get:
- Memory multiplier = 21.33 (auto)
- Frequency = 2133MHz
- Voltage 1.20V
- CAS latency = 15 (auto)
- tRCDRD = 15 (auto)
- tRCDWR = 15 (auto)
- tRP = 15 (auto)
- tRAS = 36 (auto)
So I then tried to switch to the XMP profile, which changes the settings as of:
- Memory multiplier = 36 (auto)
- Frequency = 3600MHz
- Voltage 1.35V
- CAS latency = 18 (auto)
- tRCDRD = 22 (auto)
- tRCDWR = 22 (auto)
- tRP = 22 (auto)
- tRAS = 42 (auto)
But unfortunately the motherboard does not boot properly after that change, monitor screen stays black. Finally after several auto 'reboot', I am getting back to the BIOS but the memory settings have been reverted to 2133Mhz as above.
I am not going to play that much with that build and I am primarily looking for stability, but I also would like to get a little more out of that RAM as 2133MHz is much lower than the 3600MHz they are supposed to reach.
So I guess I will now have to crank up the memory speed manually, along with playing with latency and voltage right?
UEFI BIOS is also showing lots of other advanced memory timings, should I take care of these too?
All in all, is there a good guide out there that I can follow to see what stable memory frequency my system can achieve?
