I increased the GPU to 5300 but it only reached 1780 stable. If I reduce the CPU, can I improve the GPU performance?
I increased the GPU to 5300 but it only reached 1780 stable. If I reduce the CPU, can I improve the GPU performance?
If i reduce my overclocked cpu, can i still achieve higher gpu performance? The gpu would reach 1830 on the clock when the m cpu was at 5000gz, but after some upgrades the pc improved to 5300 oc close to 5400. Once the gpu increased, it only managed to overclock to 1780. If i lower my cpu again, how much would the gpu's oc increase? Here’s the pc list:
I7 7700k
Asus Strix 1080ti OC
Asus Z270 A
Vengeance 8gb x4 2133-2400 OC
850 evga ps
Ssd samsung 240gb
2 1tb hd black
2 thermatake water cooling kits with 300l Resv
2 radiators
13 fans
All components are water-blocked and have their own water loops. The tower used is 900 by Thermaltake. Temperatures stay around 29°C to 39°C max, but the gpu now only goes up to 1780.
I haven't encountered an i7-7700k reaching 5.3GHz with stability, as achieving those speeds usually exceeds any safe or recommended Intel limits. The vcore is likely too high compared to the safe settings, and the CPU may be constrained by software optimization, which can shift BCLK instead of the multiplier. This situation can lead to significant performance drops, especially noticeable in the L1 and L2 caches, ultimately impacting GPU performance. Even with Skylake+, separating PCI and PCH clocks helps limit direct influence on GPU clocks, but other components still face challenges that may affect overall stability. If you're using the 'GO' option to force software overclocking via BCLK boost, simply disabling it might be necessary to regain control.
The CPU seems to be behaving erratically, possibly influencing the GPU clock speed.
An inconsistent CPU clock might make it look like the GPU is unstable. I used my words incorrectly. The GPU overclock isn't that high, so it's unlikely to be the cause. Probably the CPU clock is the issue—or maybe he just got a really bad Pascal card.
I haven't encountered an i7-7700k reaching 5.3GHz stably, as hitting those speeds usually requires vcore beyond any safe or recommended Intel limits. The processor appears software-limited, which shifts BCLK control rather than the multiplier, potentially causing major issues. This can significantly impact performance, especially with the L1 and L2 caches missing on the CPU, leading to a noticeable drop in FPS compared to stock settings. Although Skylake+ separated PCI and PCH clocks, reducing direct BCLK influence on GPUs, it still influences other components that ultimately affect GPU performance. If you're using the 'GO' option to force software overclock via BCLK boost, simply disabling it might help achieve more stable operation with consistent voltages and current, enabling the GPU to perform better.
