Facepalm: Microsoft started rolling out Home windows 11 24H2 this month. The key replace introduces a number of AI options and enhancements, together with some new bugs affecting unfortunate customers, on this particular case, PC house owners with SSDs manufactured by Western Digital.
Microsoft is busy rolling out the scheduled launch of Home windows 24H2, however some customers have already encountered main compatibility and stability points after putting in the improve. In latest days, house owners of NVMe SSDs from Western Digital have flooded the corporate’s boards with experiences of bugs and blue display screen of demise crashes.
Some customers report that rolling again to the earlier model of Home windows 11 (23H2) appears to resolve the crashes. A lot of the issues look like associated to WD Black SN770 and WD Blue SN580 SSDs, which lack DRAM-based cache.
These drives depend on the Host Reminiscence Buffer function launched in model 1.2 of the NVMe commonplace. HMB permits storage units to make use of the system’s major DRAM as cache, enhancing efficiency on cache-less drives. Western Digital drives sometimes allocate 64MB of host RAM by way of HMB, however Home windows 24H2 seems to be reserving as much as 200MB for caching I/O operations, doubtlessly inflicting the instability.
The extra 136MB of cache reminiscence allocation has brought about WD’s SSDs to behave erratically, forcing your complete working system right into a BSOD loop. Home windows 23H2 accurately allocates 64MB of RAM to DRAM-less SSDs, suggesting that the difficulty was launched with Microsoft’s newest Home windows 11 improve.
Since changing conventional inside testing procedures with the Home windows Insider program, Microsoft builders have more and more used PC customers as unpaid beta testers for Home windows. Generally, a Home windows 11 replace might considerably increase efficiency – comparable to doubling file copy speeds on particular file techniques – however at different occasions, “preview” updates can result in widespread BSODs, crashes, and different “unintended” points.
For SSD house owners encountering blue screens after upgrading to 24H2, there is no have to panic. A registry-based workaround is accessible to restrict HMB allocation to 64MB or disable it totally. Whereas this workaround would possibly negatively affect efficiency throughout heavy file transfers, it ought to return Home windows 24H2 to a semi-stable state after restarting the system.
