G.Skill DRAM Troubleshooting Guide
1. Make sure the motherboard and CPU can support the memory kit
a. Search the G.Skill RAM Configurator to see if the memory model is listed as compatible under the
motherboard model.

Alternatively, a 'QVL' tab is located on the product page of each memory model. Here you can see
which motherboards have been fully tested for the memory model. If a combination is listed, the
motherboard has been validated to be capable of the rated specifications of the memory kit, with a
capable CPU. Not all CPUs are natively capable, so in some cases additional adjustment in BIOS may
be necessary, especially for higher end models.

b. If a combination is listed, check to see if you have the latest BIOS / UEFI for the motherboard as
upgrades may improve compatibility.
Manufacturers continuously release improvements to better results so in many cases an update can
significantly change functionality.
The motherboard manufacturer product page should have a section for downloads of all related files
including all BIOS / UEFI versions.

c. The standard DRAM Frequency can be found on the product page of each CPU model.
Anything higher can vary depending on the over clocking margin / quality of the processor in hand.
It is up to the user to test for its maximum capability. Most new processors can support up to DDR4-
3200 or DDR5-5600, so this is mainly a concern for DDR4-3600+ or DDR5-6000+
Note: Only one kit of memory is guaranteed to perform at the rated specifications. By adding a
secondary kit, the results are no longer guaranteed and it is up to the user to test and see what the two
separate kits of memory can achieve together in a system.
2. Confirm the memory kit is configured properly
a. For two modules in a four slot motherboard, typically slots two and four away from the CPU should
be populated.
If any uncertainty, or if more than four slots, check markings on the motherboard or the motherboard
user's guide.
b. For memory kits above standard, enabling XMP / DOCP Profile will be required to run at full speed,
or manual setting of DRAM Frequency, timings, Voltage, and potentially others.
If XMP / DOCP alone do not work properly, manually set to a lower DRAM Frequency to see what can
be stable.
In case a lower DRAM Frequency is stable, it is possible the CPU internal memory controller is
overloaded.
Increasing the memory controller Voltage can force stability at a higher frequency or capacity, so you
can check the Voltage at a lower, stable DRAM Frequency, then manually set it higher to see if you can
