Running too fast or too slow?
Running too fast or too slow?
Due to the current high prices, I went ahead and purchased a pre-built Lenovo Legion TR5 and swapped out its power supply. It came with one 1x8 DDR4 stick, designed for 3200 MHz. In the UEFI it shows 3200 MHz, but when I boot up and check specs, it says 1539 MHz. I’ve never seen specs give an inaccurate value before, though it’s possible. The UEFI doesn’t offer any way to enable XMP or RAM overclocking, and it seems Lenovo’s firmware makes it hard to reach the BIOS settings. Is this just a wrong reading, or is my RAM actually running at half its speed?
DDR stands for double data rate. Multiplying 1539 by two equals 3078. That's okay.
The discrepancy comes from how Speccy interprets memory speeds. On your older system with limited RAM, it might have displayed a lower frequency to match what the hardware could actually handle. Now, with better specs or different settings, it shows the correct rate, but the halved value could be a default or a simplified representation.
Verify your RAM speed using CPU-Z. For instance, DDR 4000 operates at 2000 MHz.
He displays my 1333MHz DDR3 as 667MHz. Don't stress about the slow performance since it's operating in 8-channel mode.
