Increase your gaming frame rate on a less powerful computer? Let me assist you!
I built my girlfriend a PC with a Ryzen 7 5800X, paired it with my old RTX 2070 Super and 16 GB RAM. I upgraded myself to an RTX 3070 Ti with an i5-12400F and 32 GB RAM. Yet when playing games like Overwatch 2, Valorant, or CS2, she’s seeing almost double the FPS compared to what I’m getting. Even though my specs are much better, she’s at 500–600 FPS in Overwatch 2, 180 FPS in CS2, and 400 in Valorant—while I’m stuck around 250–400. I know these games are CPU-heavy, but the performance gap is huge. What could explain this difference?
The Ryzen 7 5800X performs better than the i5 12400F. The latter matches the gaming capabilities of the Ryzen 5 5600. The gap is only around 10%. It shouldn’t double your frame rate. First, check if XMP is activated on your system. If your RAM uses DDR4-2400 or DDR5-4000 with JEDEC timings rather than its rated speed, it will negatively impact CPU performance significantly. It’s also possible the RAM paired with the 5800X simply works better, though a big difference between DDR4-3600 CL16 and DDR4-3200 CL16 won’t show up clearly in tests but may be noticeable in real play. If RAM isn’t the issue, it’s likely you’re not simulating the same game conditions on screen effects like smoke.
The 16GB RAM was actually an 8x2 DDR4 at 3200 MHz, while the 32GB version uses a 16x2 DDR4 at 4400 MHz. Even with this setup, the RAM in my PC performs better. We were checking it under identical conditions in the same position and game area.
No issues detected. CPU and GPU never reached 75°C. Performance mode is enabled in power settings, and NVIDIA configuration is set correctly.
Your 12400F supports DDR4-4400 RAM. That’s impressive CPU IMC if true. Confirm XMP is active and the setup remains stable at that speed. Also check whether it’s running in Gear 1 or Gear 2—Gear 2 offers much better latency, which could negatively impact high FPS performance.
My XMP is turned on, the resize bar is active. Probably I'm exaggerating, I just restarted the PC so I can't see it, but I'll take some photos and share them later once everything's fixed.
Unstable RAM often causes blue screens, game interruptions, unexpected program stops, and frequent restarts. Booting indicates partial functionality, but not guaranteed reliability in every situation. It's worth checking if you adjusted the settings to use Gear 1 at those speeds—this is unlikely to make your 12400F perform well. By default, higher speeds run in Gear 2, which means the CPU's IMC operates at half its normal rate (a 2:1 ratio). This results in DDR4-4400 RAM clocking at 2200MHz while the CPU IMC in Gear 2 runs at 1100MHz, making it more stable for the processor. Using Gear 2 will likely reduce performance when aiming for higher frame rates. A chart from Hardware Unboxed illustrates 12th gen performance across various RAM setups. It's clear that DDR4-4000 G2 (Gear 2) lags behind even DDR4-2933 G1 (Gear 1).
Games usually favor lower latency over just faster clock speeds, so review latency stats in CPU-Z. Keep in mind to ensure your RAM operates in dual-channel mode. You might also want to check driver settings for any adjustments that could influence performance.
