Well we have a few motherboard lines in stock now.
DDR5 we had 100 units in stock for launch, all Corsair and these all sold out very fast, but they were on sale pre-launch and people bought them all up, we limited to 2 kits per customers, so DDR5 has a strong uptake.
DDR4 is still proving popular as well.
We feel the crazy fast kits on DDR5 won't offer much in terms of performance due to the divider reducing performance. Same as when AMD launched Ryzen 3 they marketed how all of a sudden 4000MHz plus DDR4 speeds were possible, with lots of 4400MHz example, but due to the infinity fabric divider changing around 3700MHz there was little to no performance gain, in some applications performance dropped. As such the sweet spot was and still is 3600MHz with the tightest possible timings, why I had the 8 Pack 3600MHz C14 kit created which has sold several thousand units to date.
I feel 12th gen will be similar with the sweet spot for RAM speed been around 5200MHz with tightest possible timings, maybe 5600MHz, but the 6000MHz plus kits and yes we will be offering those but my advise is don't waste your money, in fact my advice is forget DDR5 as DDR4 3600MHz offers pretty much same performance. Of course I understand customers who want to future proof themselves somewhat by getting DDR5, but whilst you can easily pickup a DDR4 kit for around £50 for 16G or around £100 for 32GB, DDR5 right now is expensive and it will for sure get a lot cheaper next year.
