Fractal Ridge Case PCIe Riser Has Trouble Running in PCIe Gen 4 Mode, Company Outs Workaround
The Fractal Design Ridge SFF tower-type case won critical praise including from us, for its unique design, well-planned interiors, and room for even triple-slot graphics cards with a little adjustments. The case relies on a PCIe riser cable to maintain its SFF form, since the graphics card has to be oriented vertically. The riser included with the case meets PCI-Express 4.0 standards, but end-users started experiencing problems running their latest-generation PCIe Gen 4 graphics cards with this case, with the problem being localized to the riser cable. Fractal investigated this issue, and confirmed the issue.
Apparently, the PCIe riser included with the Fractal Ridge, while rated for PCIe Gen 4, has a design flaw that affects signal integrity. The riser is found to be only stable with PCIe Gen 3 or lower. The company is recommending a workaround for end-users while it works on a solution: to confine PCIe to Gen 3 mode using the motherboard's UEFI setup program (BIOS setup program), in which you can restrict the x16 PEG slot to Gen 3 mode. "We are developing a solution to enable full PCIe 4.0 compatibility, but until that is ready, we will update our listings to reflect that only PCIe 3.0 compatibility is guaranteed," the company said in a statement.
