Facepalm: A major variety of X670E homeowners have been coping with an annoying concern the place their PCIe 5.0 drives are being severely throttled right down to prehistoric Gen 1 speeds. Worse but, the issues aren’t restricted to a specific mannequin or model; they’re affecting motherboards from a number of distributors like Asus and MSI.
Whereas Gen 5 SSDs have been initially working at their rated excessive speeds, affected customers started noticing main efficiency drop-offs over time. Along with gradual speeds, some customers have additionally reported their techniques hanging, crashing, or failing besides into Home windows when each the first Gen 5 SSD slot and the Gen 5 graphics card slot are populated.
Now, all of us anticipate to come across minor snags throughout a serious tech transition like PCIe 5.0. Nonetheless, this irritating scenario just isn’t what early adopters signed up for. In any case, Gen 5 SSD assist was a key promoting level for X670E. The problems have surfaced on a number of fashions together with Essential’s T700 and T705 fashions.
Asus is advising affected prospects to succeed in out to their SSD vendor for assist. In the meantime, Essential performed an investigation on their finish and decided that the wrongdoer lies with the X670E motherboards themselves.
Of their testing throughout varied X670E boards and in-house techniques, the corporate was in a position to reproduce the identical crippling slowdowns on Gen 5 SSDs. Their advice is to contact the motherboard maker about issuing a BIOS replace to handle the foundation trigger.
“We want to inform you that we escalated your concern to our devoted workforce for additional investigation, and so they knowledgeable us that the issue lies with the motherboard relatively than the Essential SSD. This conduct has been noticed throughout varied motherboards from totally different producers, and we have been in a position to replicate it on our in-house techniques as properly,” a assertion by Essential revealed on Asus’ boards reads.
“The difficulty appears to happen when a Gen5 SSD is related to a Gen5 slot on the motherboard, which is why you aren’t experiencing this downside along with your Gen4 drive. Should you have been to attach the Essential T705 SSD to Gen4 speeds always, this concern would possible be resolved,” it provides.
Whereas the precise supply hasn’t been pinpointed but, some theories are circulating. One in every of them suggests that the first PCIe 5.0 slot for graphics playing cards is sharing bandwidth with the primary Gen 5 SSD slot in sure configurations. This isn’t preferrred, as these lanes should not be mixed for optimum efficiency.
MSI has already rolled out a BIOS revision (1.0c launch) that is apparently fastened issues for some of us, although the problems persist for others.
On the brilliant facet, reverting to a Gen 4 SSD or working the graphics card at Gen 4 speeds does appear to sidestep the issues in the meanwhile. Nonetheless, that is clearly not a really perfect long-term answer for individuals who paid a premium particularly for the advantages of Gen 5.
