Upgrading the CPU caused harm to the PCIe 16x 16 port.
Hi guys, I had my i5 760 running smoothly at 3.7ghz with 580 at 900 MHz and 2100 memory. When I tried to push it to 3.8GHz, I encountered issues where the NVIDIA driver would stop responding during games or benchmarks. I did everything possible—reinstalling drivers, resetting overclocks—but nothing worked. Then I swapped the GPU to a different slot and it functioned properly again. However, the new slot is PCIe 16 x 4 (1.1 instead of 2.0). Could this affect my PCIe 16 x 16 slot? The voltages were 1050 on the GPU and 1.223 on the CPU—nothing seems too high. Any thoughts? Would running it in X4 make a big difference? Thanks in advance.
check your wood to confirm if this is still correct ??

outside of that it might be time for something more current in a modern build ??
Extremely unlikely. I've seen friends with motherboards overclocking. The power doesn't spike to your GPU. It spikes to your CPU and maybe, rarely, to RAM.
It seems the slot might have failed or something inside is causing a poor connection. Cleaning the slot and checking your GPU connections could help.
I believe you'll notice some performance drop when running at 4x speed, especially with a 1.1 slot.
don't overlook the PCIe lanes [1x16 or 2x8] that pass through the chip [cpu] on Intel; if the overclock harms the chip, it might be possible. I think this is why the disclaimer mentions overclocking is at your own risk—damage could occur.

I think this is what the disclaimer warns about—overclocking carries its own risks and damage might happen. That's a solid reminder, junkeymoney. Thanks for bringing it up. I've been using AMD builds lately.
Junkeymonkey :
It's all through the chipset, right? Why they get so hot.
Absolutely. I like the lanes on the motherboard more.
I think Intel did it to gain an edge over gamers who wanted more lanes. They knew people would pay extra for more lanes on a costly chip.
I understand it saves space on the motherboard, making smaller designs possible, but I still think marketing is involved.
Sorry if this went off topic, OP.
Hey guys, I'm going to attempt a thorough cleaning of the PCI-16 slot. So far it's been working fine in the 16x4 configuration, which means I was lucky. Thanks for all your support. Dan
It might help to try the card on a different computer and check if it reads correctly. This could indicate whether the issue is with the card itself. Did you mention any details about your system specifications or CMOS settings? Have you reset the CMOS and entered the BIOS to see if anything changes? You mentioned you thought the driver might not be responding, which usually points to the card rather than the system.
Hey there, junkymonkey, all systems are back to normal after a full reset. Since I moved slots on the motherboard, there were no issues and I even overclocked my GTX 580 to 890 at the core and 2100 on memory. The CPU ran at 3.73 GHz with dynamic voltage set to a maximum of 1.21, everything stayed stable while playing Witcher 3 at 1080p with 40 to 60 FPS on medium to high settings for over six hours straight—it performed perfectly. Another odd observation is that my CPU temperatures were noticeably lower, around 29°C, and didn’t exceed 68–72°C during playback. I’m not sure if this means I’m losing any frames with the GPU in a 16x (1.1) x4 slot, so I won’t bother changing it. It seems like the issue is mainly with my GPU—it’s not a beginner setup (though my board isn’t either). I don’t have another system to test on, but I’d be happy to try. The problem only appeared when I tried demanding tasks, like playing games or streaming. I could browse the web and watch videos without trouble, and benchmarking with PassMark worked fine, but running Heaven or other games caused errors. Strange stuff.
