ASUS ROG Strix Z790-E paired with Corsair MP600 SSD in M.2_5 port
Hi everyone, I just finished my first build using recommendations from a friend. Overall it went well, though the process was tough with all the tubing involved. The final result looks great for someone new, but starting up was tricky because the second SSD isn’t being recognized. I’ve read online that combining M.2_1 and RTX4090 might cause issues with graphics performance. To fix this, I opted for a larger drive (M.2_2, 1TB) and a bigger SSD (M.2_5, 2TB) for better cooling. So far I haven’t found any advice on whether the setup is broken or if there’s a BIOS fix needed. I’ve updated my BIOS, run the MEUpdate tool, and installed all drivers, but it still feels like something’s off. If you’re using a water cooler behind this unit, swapping it might be difficult without emptying the loop. I’m hoping someone can clarify if this slot isn’t compatible or if a BIOS change would help. Thanks for your support! I can run the OS on another drive, but it would disrupt the setup. Let’s hope this works smoothly next time!
I need to know how you confirmed it isn't detected. Check if it appears in BIOS, Device Manager, or File Explorer—each method has its own way of fixing issues. If it's missing from BIOS, consider trying another BIOS version; otherwise, you might need to reset or replace the hardware. In Device Manager, a misconfigured setting could be blocking access, or it may turn off when another device is connected. File Explorer might not recognize it if the drive isn't initialized properly. Try opening Disk Management, right-click the uninitialized drive, and format it—this often resolves the problem.
Absolutely, glad you found the answer! Your queries aren’t appearing in BIOS, Device Manager, or File Manager. There are some settings for the M.2_5 slot in BIOS, I’ll check them right away—I’m not sure about the details. Changing them didn’t resolve the issue, though it’s understandable to be frustrated after a late-night struggle.
Here only the FireCuda is visible: I discovered a setting where I can modify the M.2_5 configuration to PCIE, SATA, or Auto (I assumed I should make it PCIE, but even in Auto it doesn’t matter). It displays M.2_5(SATA Mode) as empty, which seems incorrect since it isn’t SATA. The PCIe Config section states M.2_5 is not available: This page is confusing, leading me to suspect the M.2_5 slot isn’t compatible with a NVMe SSD at all. Otherwise it should appear here. I was trying to verify if M.2_5 could actually be used or if I needed to replace the drive and rearrange the PCIe riser and power cables for the RTX 4090. This would be quite challenging. I decided to double-check. By the way, I successfully removed the SSD from the slot and reconnected it with the tubes still attached—no changes were needed.
Nope that's only for devices connected directly to the CPU. Since slot 5 is wired up through the chipset, it will only be found in the PCH menu. Slot 5 should be usable, I don't see any reason why it shouldn't be. Yeah, that sounds like either the slot or the SSD is dead. Either way it sounds like you need to pull the drive back out again and try it in a different slot, either still in this system or in another, easier to maintain system. Also make sure to quote so we get a notification, I just happened to still be on this page and saw this.
Congratulations on the great setup! It’s smart to do a mockup and test everything before you start building. Nice work on the pipes—this shows you’re handling complex design with multiple bends. Make sure to check for any BIOS updates for that mainboard and apply the latest system update.
Thanks for the feedback. There were some unusual bends and a few mistakes with the tubes, but overall I only bent about 1.5 meters of them. Since I've never bent a tube before, I'm quite happy with the result. In fact, I noticed something similar in the mockup test mentioned in "the last guide you ever need," though I wasn't sure how to handle the tougher sections. I didn’t want to spend money on soft tubes and fittings just to cool the system, and without a cooling loop I worried about damaging it.
You didn't need to simulate it. Just verify the bios are present. Filling the water blocks with cooling fluid and sealing them should suffice to load the system and confirm everything is in place. The drain port looks correct—soft tubing and a compression fitting are included. Make sure all liquid above the GPU is removed to prevent spills; you may need to rotate the system for optimal drainage. If the drain container is clean, you can reuse the fluid.
Today marked a significant moment—I emptied the system and took apart those three tubes to access the M.2 drive. I noticed the 1 TB was functioning properly in another slot, which means the problematic one isn’t there. I’m planning to get a replacement and reinstall it in the same position to avoid future issues. Perhaps I’ll make one adjustment and skip the unnecessary steps before the M.2 cooler. I’m uncertain whether I should try putting the 1 TB back into the M2.2 slot, especially if the graphics card returns later. It could be risky, but thanks for your help! Cheers, Don
