Configure RAM to use the listed speed instead of XMP.
Configure RAM to use the listed speed instead of XMP.
Hi,
I have a query about ensuring my RAM operates at the advertised speed I purchased. I recently assembled a new PC and the default RAM speed is 2133MHz, which matches expectations. The RAM I acquired is labeled for 3200MHz. I learned that XMP could potentially affect CPU performance and might raise temperatures. Should I configure the RAM manually to its rated speed on the motherboard, or would I need to adjust settings on the CPU side? Or should I simply update the BIOS values and be done?
My build details:
I9 9900k
Asus Maximus XI Hero
2x16GB G Skill Ripjaw V
RAM Specifications:
PC4-25600
Voltage
1.35 Volts
CAS Latency
16
Latency
16-18-18-38
Why bother?
Ram comes with the right configurations to operate at the advertised 3200 speed, which is built into one of the xmp profiles in the RAM. Running it faster than 2400 speed could trigger overclocking with a higher-than-usual voltage. This might affect temperatures or the overclocking process itself, no matter the settings. Using an xmp profile is simply a convenient way to achieve the optimal performance that the manufacturer has identified.
Adjust the BIOS settings precisely for timing and voltage. If initial boot fails, allow the system to attempt restarts several times (the motherboard testing alternative secondary or tertiary timings to identify a suitable configuration).
