IPASON A9-9820 motherboard for AMD_BL2 platform version 2.3
I purchased this board out of interest and for some testing with Jaguar CPU cores. However, I'm encountering significant limitations in PCIe bandwidth on the NVMe port—maximum around 795MB/s, even with a Samsung 980 Pro. The previous post mentioned higher speeds. Could you tell me how the board is set up? Are there any BIOS settings or jumper configurations that affect performance? If you own this board and your read speed aligns with the numbers below, I'd appreciate hearing about your setup!
I used Samsung Rapid option in Samsung Magician but I removed it because there's no difference and there's a chance it will corrupt your data because it's using RAM to boost the speed, more important is 4k speed that is lacking on this board at least in my tests.
I noticed you're checking the hardware setup and BIOS settings. It seems the SSD is present, but performance is limited to half the expected speed. You mentioned thinking you're achieving double the PCIe x1 bandwidth, yet you're still hitting the 800MB/s limit.
