M.2 Adapter for PCIe x4 into Asus Maximus VIII Hero
M.2 Adapter for PCIe x4 into Asus Maximus VIII Hero
I have a brief inquiry. I'm attempting to fit an M.2 adapter into my Asus Maximus VIII Hero motherboard, but after installation the PC keeps restarting without a postcode. Once removed, everything works again. I thought PCIe compatibility should handle different slot types like X4 or X8, so placement shouldn't be an issue. Do I need to adjust BIOS settings or treat it as a storage device? Appreciate any guidance, even if it seems simple. I've also installed a GeForce GTX1080 in my x16 slot. Thanks!
You’ve hit the limit on PCIe lanes. With a M.2 drive already installed, you’re essentially maxed out. Why go for more M.2 storage? Do you really want those extra speeds? If it’s just for gaming and everyday tasks, you won’t feel any difference compared to a standard SSD or M.2 drive.
Thanks for your quick response. I intended to use it for transcoding and storing encoding data for my videos since I’m running low on space on my internal M.2 slot. So, with the current setup, can I get this up and running as planned? Also, the metadata for my Plex server is already stored on the same internal drive.
I don't agree with jaslion. Having just one M.2 NVMe drive and a single GPU installed won't make all your PCIe slots unusable. The biggest issue could be that your GPU is downgraded from a higher speed to PCIe 3.0 x8 instead of x16. Have you confirmed the M.2 drive you're using is an NVMe device, not a SATA one via the M.2 slot?
That's what I believed as well. Just adjusting to two times x8. Absolutely correct. This is the NVMe storage: https://www.gigabyte.com/Solid-State-Dri...D-512GB#kf And the adapter card: https://www.lindy-international.com/PCIe...2&pi=51132
The manual indicates that placing a card in the bottom slot should turn off the x1 slots automatically, but you might need to adjust settings in the BIOS, such as disabling a setting that forces the x1s to stay enabled. If the issue persists and the BIOS isn't updated, it could be a bug.
I discovered a BIOS setting labeled: PCIEX4_3 Slot (black). You can configure it to "Auto," "X2 Mode," or "X4 Mode." Currently, it's set to "Auto." The notes explain: [Auto]: Insert an X4 card on PCIeX4_3 and switch to X4 mode; otherwise, use X2 mode. [X2 Mode]: Applies to PCIeX4_3, X1 to PCIeX1_2 and PCIeX1_3 [X4 Mode]: X4 for PCIeX4_3. Does this indicate the "third" PCIe slot?
