The information in the description is correct. DDR5 RAM uses the so-called Double Data Rate (DDR), which means that the effective data rate in MT/s is twice as high as the clock frequency in MHz. This means, for example, that 4000 MHz corresponds to 8000 MT/s. So when ASUS states 8000+ MT/s and the shop says 4000 MHz, they both mean the same performance - just expressed differently.
The PCIe slots on the mainboard share the bandwidth with the GPU, in particular the PCIe 4.0 x16 slot and the PCIe 5.0 x16 slot can share or vary bandwidth depending on the CPU type and configuration. The mainboard has a PCIe 5.0 x16 slot for the graphics card and another PCIe 4.0 x16 slot whose bandwidth varies depending on the CPU type, which indicates possible bandwidth sharing.
Hello,
I have the same configuration - with 3 SSDs from WD - do you have the latest version of the Dash Board? Just don't defragment any more - it's poison for SSDs.
The SSDs are recognised in my dashboard! Western Digital Dashboard 4.3.2.4
I think if the SSDs are running at full speed in CrystalDiskMark, then everything is fine! The dashboard monitoring seems to have errors!
I've owned this board since March, together with the Ryzen 9 9950X3D and an RTX 4080 super OC from ASUS. I find the placement of the heat sinks around the PCIe X16(G5) slots on this and many other ASUS boards problematic. The heat sinks completely block access to the release clip for the GPU. Despite years of experience, I have probably built the thing to be theft-proof. In order to get to the clip for removing the GPU reasonably well, it should at least be possible to remove the cooler from the M.2_1 slot. However, due to the case (Lian-Li o110 Dynamic XL), I had to install the Lian-Li GPU Holder (mounted over the mainboard using standoffs and a bracket on two screws) instead of a normal GPU holder, which now blocks the mechanism for removing the M.2 cooler. The GPU from ASUS, which is already massive in the 40 series, blocks the removal of this GPU holder, making it practically impossible to remove the GPU. The system runs great, but I have no idea how I could ever get the GPU out of there again, as the release clip is no longer even visible😅. How would you solve this problem? Unfortunately I can't upload a picture.
The mainboard has five M.2 slots. Of these, the M.2_2 and M.2_3 slots are shared with the GPU bandwidth, which means that the primary PCIe graphics card is reduced from x16 to x8 lanes when these slots are used. The M.2_1 slot, on the other hand, is connected directly to the CPU and does not share its lanes with the GPU. The M.2_4 and M.2_5 slots are connected via the chipset and run with PCIe 4.0 x4, but do not share lanes with the GPU.
To summarise: There is at least one M.2 slot (M.2_1) that does not share lanes with the GPU.
Hello everyone, I bought this mainboard and it runs very well except for one thing, I have 3 M2 WD Black SN850X on the board all in perfect slots so that the graphics card does not go down to x8 (lane-sharing) but in Windows 11, for example, in the Task Manager all 3 SSDs are displayed as HDDs, even in new games I get a warning that I should better install the game on an SSD. Everything should be correct in the Bios, the Device Manager says the drivers are up to date but when I start WD Dashboard my SSDs are not recognised. I have already defragmented all 3 but it still says hard drive instead of SSD. Does anyone know another tip? I've already spent hours on Google and ChatGPT didn't give me a solution either. Oh yes, fortunately Crystaldiskmark shows in the test that the SSDs are running at full speed.
The following RAM properties are relevant for the ASUS ROG STRIX X870E-E GAMING WIFI Board:
- RAM type: The board supports DDR5 RAM.
- RAM capacity: There are four DIMM slots that support up to 192 GB of RAM.
- RAM speed: The RAM speed can reach up to 8400 MHz (OC) with the corresponding processors, especially with the AMD Ryzen™ 9000 Series processors, where speeds of 8000+ MT/s (OC) are possible.
### Differences between high and lower RAM speeds
- High RAM speeds (8000+ MT/s): These can make a difference especially with demanding applications such as gaming, video editing and other high-performance tasks. Higher RAM speeds can lead to improved performance and lower latency, which is especially useful for overclocking and intensive workloads.
- Lower RAM speeds (6000 or 6400 MT/s): For general applications and less demanding tasks, these speeds may be sufficient and the difference might not be as noticeable. However, for more intensive tasks, the higher speed of 8000+ MT/s can bring a noticeable improvement in performance.
### Summary
If you use 64 GB of RAM at high speed (8000+ MT/s), you can expect better performance and lower latency for demanding applications. However, for less demanding tasks, 6000 or 6400 MT/s RAM might be sufficient without much difference being noticed. It ultimately depends on your specific needs and requirements.
