WilleHelm Posted March 2, 2024 Posted March 2, 2024 Hi! I had to replace my defective B550 mainboard with my old X470. It lacks PCIe 4.0 of course. Then I was wondering why AIDA64 still shows not only PCIe 4.0 speed, but x16 as well; because of occupied PCIe slots the first slot just has x8 speed. I use v7.00.6700, tried the latest beta, as well as an entirely new config. One more thing, which may not be related to this problem, or maybe this has changed over the years, but the bus speed does not fluctuate anymore like I remember back in the day when I had an RX 590 on the AM3+ platform. Regards, Wilhelm PS: Sorry, maybe this should rather be in the 'Bug reports' forum... Quote
WilleHelm Posted March 4, 2024 Author Posted March 4, 2024 This must be it where it get's the wrong information for "External Applications": On the other hand the correct lane count is identified here: PCI-E 2.0 is a known (cosmetical) discrepancy. Quote
WilleHelm Posted March 12, 2024 Author Posted March 12, 2024 Excellent! The latest release v7.20.6800 finally shows the correct PCIe revision! 😎 Although GPU Bus Type is still "@ 4.0 x16", I hope this is going to be fixed as the correct value is well-known of late. Quote
WilleHelm Posted March 18 Author Posted March 18 Hello! Are there any news on that matter? Since last year I have switched mainboard and I'm using the latest AMD drivers and AIDA 7.60.7300. As before, any tool like AMD's Adrenalin Software, GPU-Z, etc. detect the actual lanes available/used, even AIDA in the Chipset tab. But not in the GPU tab and subsequently the exteral app. sensor value shows x16 instead of x8 in use. Regards Quote
