Cannot upgrade to 3200 after upgrading to 4 modules
Cannot upgrade to 3200 after upgrading to 4 modules
Hello there
I recently chose to upgrade from a 2x8 G.Skill Trident F4-3200C16-8GTZR setup to four units, making it 4x8. Previously, I ran the two modules using the AXMP profile at 3200MHz without any problems.
Here are some details:
CPU: AMD Ryzen 7 2700X
Memory: MSI 450 Tomahawk max
Storage: 4xDIMMS: G.Skill Trident F4-3200C16-8GTZR
The issue appears to be that when I try to run the same AXMP profile with four modules installed, it fails. The profile activates correctly in BIOS but reverts back to 1866MHz after reboot, which I suspect is due to a safe setting in case of an OC failure.
At first, I assumed the problem might be with the new modules, so I tested them individually on the correct positions (2 and 4), which both worked fine at 3200MHz when only two were used. When manually configuring via BIOS, I reached up to 2800MHz without using the AXMP profile, after which it reset to 1866MHz—likely because of the safe setting.
I’m not very experienced with OC settings, so I’d prefer not to adjust them myself. Could you explain why the same AXMP profile at 16CL and 3200MHz doesn’t work with four modules but only two? Thank you very much for your help.
You adjusted all parameters individually (voltages, timing details, etc.)?
If not, you should apply the default configurations without XMP or must use XMP.
The settings for subtimings, voltages, etc., are stored in the SPD and applied when XMP is enabled. However, you don’t have to rely on XMP if every setting is manually configured.
I think your DRAM voltage should be around 1.35 volts? Setting the SOC voltage to 1.1 could also be beneficial.
But for a configuration like 2700x3200 Mhz it’s already quite optimal. It might be necessary to keep the frequency below 3000 Mhz, especially with four RAM sticks.
Starting with Zen2 (3xxx CPUs), the ram-controller has been enhanced to achieve up to 3600 Mhz on some processors even reaching 3800 Mhz, but...

If applicable, the settings are based on default values without XMP.
The specifications for timings, voltages, etc., are embedded in the SPD and applied when XMP is enabled.
However, if you don’t use XMP, you should rely solely on manual adjustments.
I assume your DRAM should operate at 1.35 volts? A SOC voltage of 1.1 could also be beneficial.
Yet for a configuration like 2700x3200 Mhz it’s already excellent. It might be necessary to keep the frequency under 3000 Mhz, especially with four RAM sticks.
From Zen2 (3xxx CPUs), the RAM controller has been enhanced to support up to 3600 Mhz on some processors, but not when using four sticks.
Thus, I wouldn’t choose four sticks; instead, I’d opt for two new ones (for example, replacing 4x8 GB with 2x16 GB).
