Unable to configure PCI-E to Gen 4.
Unable to configure PCI-E to Gen 4.
Hello everyone! I noticed my GPU (ASUS RX6600) is PCI-E 8x Gen 4 according to GPU-Z. Yet it displays an 8x Gen 3 speed. I attempted to adjust the PCI-E setting in the BIOS of Gigabyte Z590M, but only Gen 1/2/3 options are available (refer to attachments). It seems I might be checking the wrong section. I couldn't find any guidance online. Thanks for your help with my PC specs: Gigabyte Z590M, i5-10400F, Asus RX6600, Kingston Fury 3200MHz, 4x8GB RAM, FSP atx-500, PSU 500W Pro.
Confirmed, 4.0 compatibility is limited to the latest generation processors and they perform poorly, so avoid purchasing just for 4.0 support. Non-K CPUs have fixed CPU multiplier, XMP remains functional. However, XMP settings might not align perfectly; I recommend checking the DIMM labels for speed, voltage, and main timings and letting the motherboard handle the rest. Often the issue lies in subtimings that a specific board doesn't support, requiring all settings to be set automatically.
Slow and hungry, they're not much quicker than the 10th-gen models but deliver an incredible amount of performance (and generate a lot of heat) for the average output. They're so powerful that the i9 tier was reduced from a 10-core chip down to just 8 cores in the 11th generation. @flibberdipper is likely running an 11th-gen i3 or i5; it's quite disappointing, especially when compared to the 12th/13th gen options that offer better PCIe 4.0/5.0 support and faster speeds. The 12th and 13th generations are often criticized for high power consumption but actually perform better than the 11th in many aspects.
The 11th gen i5 (11400 specifically) really underperforms compared to the 12th gen. In the Cinebench shot, my 12600KF was likely running at 5.0PC/4.0EC, drawing around 160-165 watts, while the 11400 hit 3.6GHz and managed about 75-90 watts. The 1315U was handling 4.2PC/3.1EC and hovering near 45 watts. Also worth noting is that the 1315U has two performance cores with HT and four efficiency cores, plus only 8GB of soldered RAM (4800MHz DDR5), whereas its rivals offer 32GB of dual-channel 3200MHz DDR4. Overall, the 11th gen is pretty disappointing.
