Check your RAM performance against its specifications to see if it meets expectations.
Hey there. I understand your situation well. Your system is running on an older setup—i5-3570K CPU, GTX 660 GPU, and ASRock Z77 Extreme3 motherboard. You're planning to upgrade for longevity but want to maximize its lifespan. From what you shared, HWiNFO64 shows a clock speed of 1333 MHz, while Intel claims up to 1600 MHz for this chipset. Your RAM modules are maxing out at 2400 MHz, which suggests they’re not fully utilizing the potential. It’s possible the mismatch between your motherboard’s capabilities and your RAM configuration is affecting performance. Double-check your RAM type and speed compatibility—using modules that don’t match your system’s specs can cause instability or reduced speeds. Consider verifying the correct RAM model and ensuring it matches the supported frequencies before proceeding.
The advertised speed of DDR RAM labeled "2400 MHz" actually operates at 1200 MHz. This term refers to double data rate technology, allowing two operations per clock cycle. The reported figure is the marketing value, not the real physical frequency.
Ivy Bridge supports memory speeds up to 2400Mhz, whereas the second-gen Sandy reaches a maximum of 2133Mhz. Open BIOS, enable XMP profile, and set the memory clock to 2400MHz. This adjustment should be straightforward since RAM specifications are generally public knowledge.
I realize now I should have made the wording clearer. You were checking if the lower frequency in the memory box should be set higher, specifically 666.7 MHz. When you double it, you get 1333 MHz, which is a supported speed on my CPU. I wanted to confirm whether achieving that higher frequency was feasible given that my RAM modules actually support even faster rates.
