Question CPU performance dropped significantly After RAM upgrade ?

[hejawi]

My build is

Mobo: Asrock B450m HDV R4.0, test was done using BIOS version 7.4 and the latest one, same issue

CPU: Ryzen 5 3600 (PBO always disabled)

Old RAM: Viper Steel 8x2 3000 Mhz CL16 16 16 38

New RAM: Viper Steel 16x2 3200 Mhz CL16 20 20 40

PSU: Seasonic SII12 550 watt

GPU: RTX 4060 Ti 8GB

Windows 11 latest version and update

Chipset Driver Latest version

After installing the new rams, a drop in cpu performance not less than 5% while the ram always working on 3150 Mhz if I push it to 3400 mhz, it will work on 3350 Mhz

Using 3dmark
CPU Score was 7 287 and now 7 007
Also using CPUz
Single core was 506 now 485
Mutlicore was 4120 now 3990


Also, the Bios menu settings seems laggy a little bit

What I did:

• Change timing to 16 16 16 38
• Change speed to 3400 mhz
• Use a fix FCLK equal to half of the speed 1600 and 1700 in case of 3400 mhz
• Tried to use PBO, and overclocking CPU same results always drop in performance
• The only extra thing I did is cleaning CPU cooler and repasting again before the issue started

Hey there,

Have you installed both the old and new sets of ram together? If, so, that's probably the issue. Test each set individually.

Run memtest86+ on your ram. If it throws up errors your ram is faulty.

On a sidenote, your PSU, although decent 10 years ago, is not suitable for your build. Consider something stronger and more modern.
