How do you tell pioneers?

By the arrows in their backs. :frowning:

There is a Windows 11 bug involving VAES. What is VAES? More to the point what is data damage? This article:… translates it to encrypted data corruption. I guess Microsoft felt that data corruption would cause too much panic. I see it differently. If you don’t use unusual encryption modes, there is no problem, but data damage implies that the bug could cause damage to data you are not encrypting. Certainly scared me. Only people with Zen 3 CPUs and Windows 11 or Windows 2022 have a potential problem, as Zen 3 is the only current CPU family to enable VAES opcode support. Alder Lake does have VAES support, but it has to be enabled in the BIOS. (It is disabled by default.) I don’t use BitLocker and the most recent Windows patch is supposed to fix the problem.

The next flight of arrows will be for Zen 4 early users. The first issue is that the sweet spot for DDR5 memory in Zen 5 systems is DDR5 6000. Frequencies above that will result in a 2:1 Infinity Fabric clock. Since Raphael will consider anything above DDR5 5600 as overclocking, this shouldn’t be a big problem–unless you have already paid top dollar for DDR 6400 DIMMs. (DDR5 6400 prices are already dropping.)

My advice if you want to be a Zen 4 pioneer is to wait until B650 motherboards are available. That is assuming that there are B650 motherboards that provide enough I/O for your needs. The X670E and X670 will have two chipset/southbridge chips while B650 will have just one. Is this an advantage? Depends. If you need enough I/O to require the X670 or X670E, you either get half the bandwidth of the B650 or higher latency for one chip. The B650 with one chipset chip won’t have those design issues.
