s about M.2 storage and graphics cards
Hey there! Let's break this down in simple terms. You're using an Asus B450 TUF GAMMER motherboard and a GTX 1660 Ti with a Ryzen 5 2600 processor. You want to add an M.2 SSD, but you're worried it might affect your PCIe slot or GPU performance.
Here’s what you need to know:
- **PCIe lanes**: This refers to how many data paths your motherboard has for connecting devices. The GPU usually uses its own lanes, so adding an M.2 SSD won’t block the GPU if it has enough space and the right slots.
- **GPU performance**: If you use PCIe 3.0 x8 or x16, it means the slot supports faster speeds. Most modern GPUs work well with these settings.
- **M.2 vs SATA**: M.2 is faster than SATA, but if you switch to M.2, make sure your GPU and other components are compatible. Some GPUs need specific slots or configurations.
- **GPU slot placement**: Putting the GPU in the main slot or a second slot doesn’t usually matter much, as long as it’s in the right PCIe lane. Just check your motherboard manual for details.
In short:
- Use an M.2 SSD if you want faster storage.
- Make sure your GPU is in the correct PCIe lane.
- Don’t worry too much about the slot number—just follow the instructions.
If you’re still unsure, just ask again and I’ll explain it simpler! You’re not alone here. 😊
The B450 chipset features a PCIe 16x slot with direct connections to the CPU, bypassing the chipset itself. This means additional peripherals won't affect its performance. AM4 Ryzen processors offer 24 PCIe lanes, divided into specific categories: 16 for the GPU (with options for SLI configurations), 4 for an M.2 SSD slot, and 4 for the main chipset. Any other devices like network cards or storage controllers will share those remaining four lanes.
Thanks! Yes, it seems the same applies—each GPU slot accommodates 8 lanes regardless of placement.
I'm sorry you didn't cover that earlier. On your board, keep the GPU in the top slot—it's the only one with direct CPU access. The second slot is connected through the chipset and only uses shared lanes. I noticed my mention of SLI boards was meant for A470, not B450.
The motherboard terminology refers to the shared four lanes. Understanding this clarifies that the primary 16x slot must host a GPU. The remaining 16x can accommodate devices like storage controllers or network cards, which may use a 16x interface but operate at reduced bandwidth. AMD Ryzen™ and Radeon™ models are compatible with these configurations. It's important to note that only PCIe 2.0 slots are supported, which limits the GPU performance to half-speed. This creates a significant bottleneck.
It's understandable to be frustrated. Your new GPU is taking up too much space, pressing against the CPU cooler. I know you wanted to put it in the secondary slot, but it’s overheating—reaching 83°C during heavy gaming sessions. I’m planning to order a better case within two days for improved cooling.
GPU temperatures around 83 are normal. You might be missing out on slight improvements, but they’re minor. If you’re getting a new case, ensure it has strong front and rear fans for optimal airflow across the GPU. Placing the card next to the CPU cooler isn’t great, though pressure isn’t a big issue. Unless you’re pushing extreme overclocks, a dedicated cooler for your 2600 isn’t necessary—you probably won’t need to replace it. If you must, you can likely find affordable Wraith Prisms on eBay (the larger stock cooler that comes with premium AMD chips).
The CPU runs at 25°C and the GPU at 30°C. No overclocking is being applied. Under heavy use for extended periods the CPU stays below 52°C but the GPU heats up significantly reaching 83°C. It’s not a cause for concern, especially with the mentioned micro ATX case. I believe the new model could help. I’ll check performance with this case; if no major change appears, I’ll consider a smaller cooler.
